Abstract
The invention discloses a flame retardant plastic composite material. The flame retardant plastic composite material comprises the following components in parts by weight: 40-60 parts of PBT resin, 20-40 parts of ABS resin, 1-3 parts of ethylene-butyl acrylate copolymer and 10-30 parts of flame retardant, wherein the flame retardant is formed by blending aluminum hypophosphite, 10-(2,5-dihydroxyphenyl)-10-hydro-9-oxa-10-phosphaphenanthrene-10-oxide and 2-carboxyl ethylphenyl phosphinic acid in the mass ration of 1: 1: 1. The flame retardant plastic composite material is good in flame retardant efficiency, does not contain halogen flame retardants, cannot cause secondary pollution, and can be used for forming large workpieces such as electric appliance shells and automobile components.
Description
Technical field
The present invention relates to a kind of plastics, be specifically related to a kind of flame retardant plastics matrix material.
Background technology
In recent years, plastics industry obtains significant progress, wherein engineering plastics particularly ABS obtain Regular application in fields such as electrical equipment, traffic, computers.ABS is the maximum engineering plastics of consumption, it is acrylonitrile-butadiene-styrene copolymer, there is the characteristics such as good fluidity, mechanical property is high, surface quality is good, but ABS itself be easy to burning, not ageing-resistant (easily turn yellow), thermotolerance is low, price is high etc., and shortcoming also limit its application.Traditional flame-proof ABS adopts the composite antimony containing compounds of brominated flame-retardant, but bromide can produce toxic gas between main combustion period, and antimonous oxide is also toxic, causes negative impact to HUMAN HEALTH and environment.
In order to realize the environmental protection halogen-free flameproof of ABS; many investigators are studied, mainly replace bromide and antimonous oxide by oxyhydroxide (as aluminium hydroxide, magnesium hydroxide) or phosphonium flame retardant (as red phosphorus and phosphoric acid salt etc.).But the flame retardant effect of oxyhydroxide is poor, need addition large, worsen thereupon bringing the decline of the process flowability of ABS and mechanical property and cannot use.And the flame-retardant system of nitrogenous, phosphorus is as a kind of novel Green Flammability system, having higher flame retarding efficiency, is the main trend replacing bromine-containing compound at present.In addition, PBT (polybutylene terephthalate) has the characteristic that height is heat-resisting, high strength, ageing resistance are good, and price is lower, be also apply engineering plastics more widely, but its toughness is poor, processing fluidity is bad, surface property is bad, due to PBT and ABS poor compatibility, and simple blend poor performance, particularly impelling strength is low, therefore needs increase-volume and toughness reinforcing.
Flame-retardant PBT/ABS alloy material of the prior art, or be not halogen-free environment-friendly flame-proof, or be that impelling strength is lower, or be that mobility is bad, range of application is not extensive.。
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of flame retardant plastics matrix material.
A kind of flame retardant plastics matrix material, comprises the component of following weight part: PBT resin 40-60 part, ABS resin 20-40 part, ethylene butyl acrylate copolymer 1-3 parts, fire retardant 10-30 part.
Preferably, described fire retardant is hypo-aluminum orthophosphate, 10-(2,5-dihydroxy phenyl)-10-hydrogen-9-oxa--10-phospho hetero phenanthrene-10-oxide compound, 2-carboxy ethyl phenyl Hypophosporous Acid, 50 form according to mass ratio 1:1:1 is blended.
Hypo-aluminum orthophosphate, No. CAS: 7784-22-7.10-(2,5-dihydroxy phenyl)-10-hydrogen-9-oxa--10-phospho hetero phenanthrene-10-oxide compound, No. CAS: 99208-50-1.2-carboxy ethyl phenyl Hypophosporous Acid, 50, No. CAS: 14657-64-8.
Flame retardant plastics matrix material of the present invention can adopt this area universal method to be prepared, as taken each component by proportioning, and mixing, melting mixing, extruding pelletization.
Flame retardant plastics matrix material good flame retardation effect of the present invention, and do not use halogen containing flame-retardant, can not secondary pollution be caused, may be used for shaping large-scale product, as electric appliance casing, trolley part etc.
