Problems solved by technology

However, the highest fire resistance level of this material is B1 level self-extinguishing from fire or V0 level. It can work in a small local fire scene, but its fire resistance performance will not work in a large or very large range of fire. It will also serve as a medium for fire expansion

Abstract

The invention provides a Grade-A fireproof material based on ABS (acrylonitrile-butadiene-styrene) plastic, which is prepared from the following components in parts by mass: 100 parts of ABS, 8-10 parts of char forming agent, 10-15 parts of borax, 2-8 parts of ammonium polyphosphate, 4-8 parts of antimony trioxide, 4-8 parts of N-phenyl maleimide, 15-25 parts of zinc borate, 30-40 parts of smoke inhibitor, 20-40 parts of hydroxide, 10-20 parts of flame-retardant polyether, 4-8 parts of chromium aluminum phosphate, 20-30 parts of expandable graphite, 1.6-3.8 parts of decabromodiphenylethane, 5-10 parts of bis(2,3-dibromopropyl)fumarate, 0.05-0.5 part of coupling agent and 10-18 parts of coupler-treated calcium carbonate. All the indexes of the ABS plastic product satisfy the Grade-A fireproof non-inflammable standard for national construction materials, and the strength and toughness are better than those of like products.

Description

technical field [0001] The invention belongs to the field of organic polymer materials, in particular to a composition containing acrylonitrile butadiene styrene polymer. Background technique [0002] ABS (acrylonitrile-butadiene-styrene) resin is a terpolymer developed on the basis of polystyrene resin modification, in which A represents acrylonitrile, B represents butadiene, and S represents styrene. ABS plastic is non-toxic, tasteless, and its appearance is ivory translucent, or transparent granules or powder. The density is 1.05~1.18g / ㎝ 3 ,The shrinkage rate is 0.4%~0.9%, the elastic modulus is 2GPa, the Poisson's ratio is 0.394, the hygroscopicity is <1%, the melting temperature is 217~237°C, and the thermal decomposition temperature is >250°C. It has excellent mechanical properties, its impact strength is excellent, and can be used at extremely low temperatures; ABS plastic has excellent wear resistance, good dimensional stability, and oil resistance, and can b...
