Flame retardants of ABS resin
ABS resin has good impact resistance, rigidity and other mechanical performance and excellent processing performance, easy coloring and coating, electroplating, widely used in machinery industry, automobile industry, electronics industry, instrument industry, textile industry and construction industry, the world ABS production and consumption market center to Asia, has become Chinese the most important market for ABS, development of flame retardant ABS resin also flourish.
In a variety of special resin ABS flame retardant ABS is one of the most important varieties of ABS resin used in computers, office machines, telecommunications equipment and other occasions the flammability requirements in accordance with the relevant provisions of the United States safety laboratory standard UL 94, and with the increasing awareness of environmental protection, have higher requirements for flame retardant products the safety of environmental protection, the EU ROHS directive stipulates that starting 6 kinds of harmful substances containing electrical and electronic equipment into the EU market in July 1, 2006 (lead, mercury, cadmium, six chromium, polybrominated biphenyls and polybrominated diphenyl ether two) shall not exceed the prescribed standards.
The flame retardant ABS resin is the development direction of multifunction and high performance, such as flame retardant, flame retardant weatherability, flame retardant ABS resin due to the effect of various additives, and in order to ensure the good performance of shock, the need to improve the proportion of ABS grafted rubber powder or with chloride polyethylene, SBS, resulting in heat the performance of a serious loss, heat deformation temperature decreased significantly, generally only 73~78 C (ABS thermal deformation temperature of about 85~9O DEG C), and its application in computer, telecommunication equipment, household electrical appliances such as electric cooker, microwave oven, electric fan and other fields and having good heat resistance.
The application of phosphorus and bromine flame retardants in PC and ABS alloys. PC / ABS alloy has excellent comprehensive properties. Although PC itself has a certain flame retardancy (LOI=25%), the flame retardancy decreased after blending with ABS. In order to meet the application of PC / ABS alloy in electronic, electrical switches, electrical appliances and other fields, the flame retardant must be added. The commonly used flame retardants in commercialized flame retardant PC / ABS alloys are brominated flame retardants, such as brominated epoxy resin, brominated polycarbonate, brominated polystyrene, ten bromo two phenyl ethane, phosphate ester flame retardants. For example, TPP, RDP, BAPP; phosphorus one bromine structural flame retardant, such as phosphoric acid three (2, 4 one or two bromo phenyl ester), the commodity brand is KroitePB - 460. Their flame retardant PC / ABS alloys have their own characteristics.
The flame retardants used in the flame retardant PC / ABS alloy were compared. The results show that when the PC / ABS ratio was 7:3. Brominated flame retardant flame retardant PC / ABS alloy was about l3%, the flame retardant properties of materials can reach UL-94V-0 level (1.6nun); phosphate flame retardant agent due to the retarding effect of ABS is not good, only in the material in the mass fraction of PC is greater than 70% when only the flame retardant effect.

Flame retardant TPP has many advantages, such as excellent transparency, softness, bacterial resistance, and water proof, grease-proof, good electric insulation, as well as good compatibility. Flame retardant TPP is mainly used as the flame-retardant plasticizer for cellulose resin, vinyl resin, natural rubber and synthetic rubber. And it may also be used as the flame-retardant plasticizer for glyceryl triacetate thin ester and film, rigid polyurethane foam, phenolic aldehyde resin, and PPO, etc.
Flame retardant TPP is a kind of halogen-free environment-friendly flame retardant with phosphorus element. Most of the products in the market are self-colored flaky crystal, our product is self-colored crystalline powder, and is more soluble in organic solvents. TPP is not soluble in water, but soluble in benzene, chloroform, ether and acetone, and slightly soluble in Z alcohol. Flame retardant TPP is nonflammable with slight aromatic odor and slight deliquescence. The fusion point is about 50 ℃, and fast melts to hoop-shape when heated. The lubricate effect is excellent, and it is often used as the flame retardant plasticize lubricant. What is more, it is used as the flame retardant for many plastics and resins, such as phenolic aldehyde resin, epoxy resin and so on.
A phosphate flame retardant with bromine Jing, even in the material in 50% mass fraction of PC, can reach uL-94V-O level (1.6mm), phosphorus and bromine have synergistic effect in the PC / ABS alloy, the phosphate flame retardant with bromine compound used in flame retardant agent, PC / ABS alloy. It also has a similar effect.
Expandable graphite is a new kind of meta halogen flame retardant in recent years. It is treated by the sulfuric acid of natural graphite, then washed, filtered and dried, and then in 900~1000. It is made under C. The initial temperature of expandable graphite expansion is about 220 degrees. Generally, it begins to expand slightly at 220 C, and 23O expands rapidly at 28O C, and then it reaches 100 times or even 280 times of its original volume.
Expandable graphite mainly following function; formation of carbon layer tough on polymer surface, fuel and heat separated; absorbs heat in the expansion process, reduce the temperature of the system; the release of ions in the interlayer in the expansion process, promote the dehydration carbonization, and the combination of combustion generated free radicals thereby interrupting the chain reaction. The combined use of expandable graphite with phosphorus compounds and metal oxides can produce synergistic effect, and a small amount of expandable graphite can achieve the purpose of flame retardant.
The FR-101 flame retardant is a milk white to yellowish thick liquid containing halogen, three oxidation of two antimony and double bonds. The density (20) is 1.8 ~ 2.2Mg / m3, the viscosity (-4 cup) is 80 ~ 100s, acid value is 3 to 5mgKOH / g, and the content of chlorine is 48%-52%.
FR-101 flame retardant can be used as both additive and reactive. It is mainly used as a durable and weatherproof flame retardant for various kinds of unsaturated polyester. The flame retardant effect is good, adding 20phr pair, oxygen index can reach more than 32. The viscosity of the unsaturated polyester has little change. Good compatibility and cross linking with unsaturated polyester. It does not affect the physical and mechanical yelling performance of the products.
With the requirement of flame retardance of polyurethane, polyolefin and various engineering plastics, the research of Organophosphorous flame retardants is becoming more and more active. Its developing trend is improving thermal stability and flame-retardant efficiency. A series of halogen-free organophosphorous flame retardants with good performance have appeared.
