Modified ABS (Acrylonitrile Butadiene Styrene) flame-retardant environment-friendly alloy

Abstract

The invention discloses a modified ABS (Acrylonitrile Butadiene Styrene) flame-retardant environment-friendly alloy which comprises the following components in parts by weight: 1-2 parts of PE (Polyethylene) ester, 2-8 parts of zinc borate, 1-9 parts of diacetone salt, 10-30 parts of PBT (polybutylene terephthalate), 30-40 parts of ABS, 10-15 parts of modifier, 10-19 parts of pigments, 10-25 parts of diluent, 10-25 parts of toughening agent, 10-35 parts of active calcium, 20-35 parts of stearic acid, 21-23 parts of lithopone, 1-3 parts of carbon black, 1-9 parts of nano calcium carbonate, 1-9 parts of stearic acid, 1-8 parts of talcum powder, 2-9 parts of ethylene-propylene-diene rubber and 3-6 parts of anti-impact agent. According to the modified ABS flame-retardant environment-friendly alloy, as a synergistic effect between montmorillonite and a halogen-free flame retardant is utilized, not only is a traditional flame-retardant system eliminated, but also excellent flame-retardant property and mechanical property are achieved; the modified ABS flame-retardant environment-friendly alloy has no damage to environment and personal health, thereby belonging to an environment-friendly product; and in addition, the use amount of the flame retardant is reduced due to use of montmorillonite, so that the mechanical property and the heat resistant property of the flame-retardant material are greatly improved, and more importantly, the production cost is greatly reduced.

Description

Technical field [0001] The invention relates to a modified ABS flame-retardant environmentally friendly alloy. Background technique [0002] Nearly 95% of the flame retardants used in the current flame retardant PBT / ABS are halogen-containing flame retardants, which have little impact on the performance of the material, and the price is moderate. Its efficiency / price is not comparable to other flame retardants. Therefore, my country provides 70% to 80% of exported electrical and electronic products use such flame retardants. However, in recent years, halogen flame retardants have been plagued by the problem of dioxins. At the same time, their flame-retardant polymer materials will generate a large amount of smoke and corrosive gases during thermal cracking and combustion. At present, the European Union and Japan have issued laws to prohibit their use. Such flame retardants. The EU has fully implemented the ROHS Directive on July 1, 2006. The decree requires that electrical and e...

However, in recent years, halogenated flame retardants have been troubled by the problem of dioxins. At the same time, the use of flame-retardant polymer materials will generate a large amount of smoke and corrosive gases during pyrolysis and combustion. At present, the European Union and Japan have successively issued laws and regulations to prohibit the use Such flame retardants
