What is the difference between fire retardant paint and fire retardant coating Ingredient
2022 / 05 / 14
Fire retardant paint is a kind of flame retardant coating made of film-forming agent, flame retardant, foaming agent and other materials. Fire-retardant coatings, which can be called flame-retardant materials, are composed of coating components such as binders (ie, film-forming substances), pigments, common coating additives, fire-retardant additives, and dispersion media. Except for fire retardant additives, other coating components have the same functions in coatings as in ordinary coatings, but some have special requirements in terms of performance and dosage. Application scope: In addition to the flame retardant treatment of wires and cables in power plants, industrial and mining, telecommunications and civil buildings, fire retardant paints also have fire protection for wood structures, metal structures, and flammable substrates of underground works. Suitable for home use. Fire retardant coatings are mainly used on the surface of flammable substrates, which can reduce the flammability of the material surface, prevent the spread of fire, and have wear resistance, water resistance, heat resistance, etc. It is generally suitable for veneers, wood and steel structures, and Most of the fillers are environmentally friendly, such as halogen-free flame retardants,
Flame Retardants: Background and Effectiveness
2022 / 05 / 14
Fire safety can be achieved by means of active or passive fire protection. Passive fire protection involves using materials or products with superior fire performance so as to either minimize the probability of ignition or, if ignition does occur, minimize the damaging effects of the resulting fire. Flame retardants offer one way of providing passive fire protection. When a combustible material (often a polymer) is used in applications where fire safety is important, the lack of intrinsic fire safety must be addressed to provide passive fire protection. There are four possible approaches, the first two involving flame retardants. · Adding flame retardants (i.e., using additive flame retardants) · Creating new materials with better fire performance though syntheses of variations of the material (i.e., using reactive flame retardants) · Blending or otherwise compounding the material with other materials with better fire performance (i.e., creating blends or mixtures) · Encapsulating the material or separating it from potential exposure to the heat insult (e.g., using barriers). Typical applications where fire safety

Flame retardants are a tool that can have a favorable effect on every key fire property, including ignitability, flame spread, heat release, and ease of extinction; albeit they do not necessarily have all of these effects simultaneously in every case. Some examples follow associated with well-known products in actual use where the effectiveness of the appropriate flame retardant system has been well demonstrated or even incorporated into codes or regulations. It is not possible to assign a particular flame retardant to a specific application, since many different flame retardants can be used for a variety of applications and vice versa. Wood behaves very differently if it has been treated with flame retardants to obtain fire-retardant-treated wood (FRTW). Standard wood panels tend to exhibit a flame spread index (FSI) of between 75 and 200 (in the ASTM E844 test), while FRTW panels exhibit an FSI of under 25 and are accepted in many more applications than standard wood panels. Recent heat release work has shown that the peak heat release rate [in the cone calorimeter] for both low density and medium density particleboards decreases when flame is retarded.5 Similar results exist for larch and thermowood pine.6 In all the cases reported, the treated wood materials were also less easily ignitable. Cellulose loose-fill is a product used for insulating attics, although it has relatively poor fire performance. Regulations and codes require the product to meet a critical radia

PVC Lubricant is an indispensable additive in PVC processing. Adding appropriate amount of lubricant in PVC can reduce the friction between particles and macromolecules in PVC melt before PVC melting; Reduce friction between PVC melt and plastic mechanical contact surface. Appropriate amount of lubricant can improve the fluidity of PVC melt, improve production efficiency, prevent the degradation of PVC caused by friction heat, and improve the appearance quality of products. According to the function can be divided into external lubricants and internal lubricants. The external lubricant has poor compatibility with PVC and is easy to migrate from the resin melt inside to the surface, forming the lubricant interface layer, thus reducing the friction between particles and mechanical contact surface between PVC melt and plastic before PVC melting. Internal lubricant contains polar groups, and has good compatibility with PVC, can reduce PVC intermolecular force, reduce melt viscosity, improve melt fluidity. The division of internal and external lubricants is only relative, and there is no strict classification standard. In resins with different polarities, the role of internal and external lubricants may change. For example, alcohol stearate, amine stearate, butyl stearate, and monotriglyceride stearate provide internal lubrication for polar resins (such as PVC and PA), but show external lubrication for non-polar resins (such as PE and PP). On the contrary, macromolecule paraffin and other polar resin compatibility is poor, such as in polar PVC used as external lubricant, and in PE, PP and other non-polar resin is internal lubricant. At different processing temperatures, the role of internal and external lubricants will change, such as stearic acid and stearic alcohol used in PVC calendering molding early, due to low processing temperature, poor compatibility with PVC, mainly pla

PVC resin is a hard and brittle material with poor impact resistance strength, generally only 3-5kJ / m.The main reason for the need to improve the impact resistance strength is its sensitivity to the gap, but also to improve the low-temperature shock resistance performance.At present, through the PVC polymer blend resist modifier technology, can effectively harden brittle hard PVC, this kind of resist modifier is a certain compatibility with PVC polymer elastomer, it can make the mixing system can maintain UPVC high modulus, high rigidity, and can greatly improve the gap impact intensity, obviously improve the low temperature impact intensity.Currently, common PVC antioxidants are chlorinated polyethylene (CPE) ,chloride polyethylene, by part of HDPE chloride due to the existence of chlorine atoms, CPE has softness and some rubber properties, and make CPB become a polar polymer and has the same polar group with PVC, increase the compatibility with PVC, so the polymer chain can maintain enough large van der Waals force to improve the impact resistance of PVC, play a toughening role.Moreover, CPE has the function of promoting PVC melting and accelerating plasticizing, and with the increase of CPE dosage, the plastic time shortens the plastic torque, the balance torque increases, and the viscosity of the plastic melt increases. Chlorinated polyethylene (CPE) is a powder product using HDPE in the water phase. With the increase of chlorination degree, the originally crystalline HDPE gradually becomes a non-crystalline elastomer.For the CPE used as a tougher, the C1 content is generally 25-45%.CPE has a wide range of sources and low price. In addition to its toughening effect, it also has cold resistance, weat

Chemical blowing agents are divided into inorganic blowing agents and organic blowing agents.Organic foaming agents mainly include the following categories:1. Azo compound2. Sulfonyl hydrazide compounds3. Nitroso compoundsInorganic foaming agents mainly include the following categories:Carbonate: An inorganic foaming agent, mainly calcium carbonate, magnesium carbonate, and sodium bicarbonate. Among them, sodium bicarbonate is a white powder with a specific gravity of 2.16. The decomposition temperature is about 100-140℃, and part of CO2 will be released, and all CO2 will be lost when it reaches 270℃. Soluble in water but not in alcohol.Water glass: Sodium silicate, when mixed with glass powder and heated to about 850℃, it reacts with the glass and emits a large amount of gas. At the same time, it can strengthen the compressive and tensile strength of the material. It is mainly used as a foaming agent for preparing foam glass. .Silicon carbide: The main foaming agent used in the current industrial production of foam glass, which emits a large amount of gas during sintering at 800-900°C.Carbon black: It is also a very easy-to-use foaming agent. It emits CO2 when heated and has a good foaming effect, but the disadvantage is that the price is higher.Commonly used physical blowing agents are low-boiling alkanes and fluorocarbons. The physical foaming agent is a compound physical foaming agent, which not only has the advantages of high foaming ratio, good foam stability, low bleeding, etc., but also has a certain modification effect on magnesite cement and reduces product halogenation. Probability of frost. Physical foaming agents have been widely used in the production of foamed magnesite products such as fireproof boards and lightweight partition boards, and in some products (magnesite fireproof door cores, etc.), they have
PVC lubricant product categories
2022 / 05 / 07
The lubricant is to neutralize the mold release of the product during plastic processing, and prevent defects caused by adhesion in the machine or mold. Generally added to the molding compound or coated on the surface of the mold cavity. Commonly used lubricants include fatty acids and their salts, and long-chain aliphatic hydrocarbons. According to the different mechanism of lubricant action, it can be divided into external lubricant and internal lubricant.(1) External lubricant: This lubricant has poor compatibility with the resin used for molding, so it is commonly used in molding processing machinery or molds. A lubricating layer is formed between it and the resin to facilitate resin flow and product release. , Such as paraffin.(2) Internal lubricant: This type of lubricant has good compatibility with resin, and is often mixed into resin to reduce the melt viscosity of the resin and improve its fluidity. Such as butyl stearate, lead stearate and so on. Stearates are both good lubricants and effective stabilizers.
Main performance of commonly used PVC lubricants
2022 / 05 / 07
(1) Calcium stearate: White powder, melting point 148-155℃, non-toxic, excellent lubricity and processability, no vulcanization pollution, combined with basic lead salt and lead soap, can increase the gelation speed, the dosage is generally 0.1-0.4PHR. (2) Oxidized polyethylene wax White or light yellow powder or particles. Although oxidized polyethylene wax contains a small amount of polar groups, it is still incompatible with PVC, but it has high lubrication efficiency, which can improve the lubricity between polymer and metal, increase extrusion efficiency, and improve The dispersibility of the colorant gives the product good transparency and gloss. The dosage is 0.1-0.5PHR. (3) Stearic acid White or light yellow particles, melting point 70-71°C. Slowly volatilize at 90-100℃, used as external lubricant in hard PVC processing, the dosage is generally 0.2-0.5PHR, and it has the effect of preventing chromatographic scaling, but if the dosage is too large, it will bloom. (4) Glyceryl stearate Powder, melting point 85-87℃, has excellent heat resistance and fluidity, can increase the amount of filler, and can promote plasticization. Used together with waxes can improve the thermal stability of PVC-U. The general dosage is 0.2-0.6PHR. In practice, people have found that when two or more lubricants are used in combination, they have different effects than when used alone. In the formula of profiled materials, most of them adopt the compounding method (5) Paraffin It has a melting point of 57-63°C and does not contain polar groups. It is a typical external lubricant. Because of its low melting point, easy evaporation and low melt viscosity, it can only provide lubrication in a narrow range. It is suitable for single and twin screw extruders. The general dosage is 0.1-0.8PHR. This product has poor transparency and whi
Common mistakes in the use of flame retardants
2022 / 05 / 07
Misunderstanding 1: The larger the amount of flame retardant, the better the flame retardant effect. The limiting oxygen index (LOI) and UL-94 test results show that the flame retardant performance of the material is related to the flame retardant dosage. With the increase of flame retardant content, the flame retardant effect first increases and then decreases. Too much flame retardant can have a significant impact on the mechanical properties of the material. Misunderstanding 2: The higher the flame retardant rating, the better. In general, people always want their materials to have a higher flame rating. However, in fact, various flame retardant test methods have limitations, and their conclusions are relative. For example, UL94 V-0 is better than V-2, however, some electrical products require arc ignitable materials and V-2 is better than V-0. Since V-2 plastic does not form conductivity and coke under the action of electricity, the possibility of fire is greatly reduced, but V-0 plastic is the complete opposite. Novista Group supplies DBDPE, BDDP, FR245, TTBP,SR130 to global market.
Microencapsulated red phosphorus flame retardant
2022 / 05 / 07
Among halogen-free flame retardants, red phosphorus flame retardants are good flame retardants with low addition amount, high flame retardant efficiency and smoke. It has the advantages of low toxicity, low toxicity and widespread use. When red phosphorus is used in combination with inorganic flame retardants such as aluminum hydroxide and effervescent graphite, halogen-free composite flame retardants, such as phosphorus/magnesium, phosphorus/aluminum and phosphorus/graphite, can be prepared, resulting in a large amount of flame retardants. fuel. Can be reduced. Improve the processability and physical and mechanical properties of plastic products. However, ordinary red phosphorus is easily oxidized, easily absorbs moisture in the air, easily causes dust explosion, is difficult to transport, and has poor solubility in polymer materials, so its application range is limited. To remedy this shortcoming, microencapsulated red phosphorus can be prepared using a microencapsulation process. Microencapsulated red phosphorus not only overcomes the inherent shortcomings of red phosphorus, but also has the advantages of high efficiency, low smoke, and no toxic gas. Its dispersibility, physical and mechanical properties, thermal stability and flame retardancy are improved and enhanced. Novista Group supplies equivalent of FP-2100JC, FP-2200S, FP-2500S, Exolit OP1230, OP930, OP1312, OP1314 to global market.
Some common PA (nylon) flame retardants
2022 / 05 / 07
Halogen/antimony or other flame retardant synergistic systems, halogen-free flame retardant systems based on red phosphorus or melamine. From a quantitative point of view, the halogen/antimony synergistic system is still the most widely used PA flame retardant system. In some parts of Europe and Asia, efforts are underway to find alternatives to halogenated flame retardants. However, these alternative systems are generally considered to have problems such as poor thermal stability and hygroscopicity. For red phosphorus, there are storage issues due to its flammability. The following are the main flame retardants used in nylon and their advantages and disadvantages. 1. Halogen-containing flame retardant system: A brominated styrene polymer with excellent thermal stability that is important and widely used abroad is being melt-mixed with PA. The process has good fluidity. In addition, the flame retardant PA prepared with it also has excellent electrical, physical and mechanical properties. The limitations of this flame retardant are its low photostability and incomplete compatibility with PA. It is also more expensive than decabromodiphenyl ether, which is widely used in China. Another flame retardant that has been used in PA for many years is flammable. This is a chlorine-containing flame retardant with high efficiency and electrical properties, but limited thermal stability. Only suitable for low processing temperature nylon flame retardant systems. Currently, the widely used flame retardant in China is decabromodiphenyl ether. Due to its high bromine content, PA has high flame retardant efficiency and is an economical flame retardant. However, since it is a filled flame retardant, it has a large detrimental effect on the flowability of processing and the physical and mechanical properties of the product. It also has poor thermal and light stabi
