Unsaturated resin flame retardant classification and description, who can provide?
Brominated flame retardant brominated compounds containing bromine containing flame retardants including aliphatic, alicyclic and aromatic aliphatic, aromatic, this kind of flame retardant and high efficiency, the flame retardant effect is two times of the chlorine flame retardant, relatively low dosage, has almost no effect on the mechanical properties of the composites, and can significantly reduce the the content of hydrogen halide in the gas, and this kind of flame retardant and matrix resin compatibility is good, even in harsh conditions without spewing phenomenon.
Inorganic flame retardant inorganic flame retardant is a kind of flame retardant based on its chemical structure and habits, including antimony oxide, aluminum hydroxide, magnesium hydroxide and zinc borate.
Flame retardant, organic phosphorus polymer added metaphosphate type flame retardant flame retardant the combustion generated can form a stable, covered on the surface of the composite materials from oxygen and combustible, play the effect of flame retardant, the flame retardant effect is better than that of bromide, to achieve the same effect of flame retardant, bromide dosage phosphide 4 ~ 7 times. This type of flame retardants are mainly phosphorus (phosphine) ester and Halogenated Phosphate and phosphorus halide, widely used in epoxy resin, phenolic resin, polyester, polyurethane, polycarbonate, polyvinyl chloride, polyethylene, polypropylene, ABS etc..
Because of its cheap personality, chlorine flame retardants and chlorine flame retardants are still a large number of flame retardants. Chlorinated paraffin chloride content was highest in flame retardant industry important, due to poor thermal stability, only suitable for processing the composite temperature below 200 DEG C, chlorinated alicyclic and four chloro two formic acid anhydride, high thermal stability, commonly used as a flame retardant unsaturated resin.
