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 are and in particular to a kind of flame retardant plastics composite.
Background technology
In recent years, plastics industry has obtained significant progress, wherein engineering plastics particularly ABS
Obtain specification application in fields such as electrical equipment, traffic, computers.ABS is that consumption is maximum
Engineering plastics, it is acrylonitrile-butadiene-styrene copolymer, has good fluidity, mechanics
The characteristic such as performance is high, surface quality is good, but ABS be readily burned in itself, not ageing-resistant (mutability
Yellow), also limit its application the shortcomings of thermostability is low, price is high.Traditional flame-proof ABS is
Antimony containing compounds are compounded using brominated flame-retardant, however, bromide can produce during burning
Poisonous gas, and antimony oxide is also toxic, causes negative shadow to health and environment
Ring.
In order to realize the environmental protection halogen-free flameproof of ABS, many researcheres have been carried out studying,
Mainly pass through hydroxide (as aluminium hydroxide, magnesium hydroxide) or phosphonium flame retardant (as red phosphorus and
Phosphate etc.) replace bromide and antimony oxide.But the flame retardant effect of hydroxide is poor, need
Want addition big, decline therewith the process flowability bringing ABS and mechanical property deteriorates and nothing
Method uses.And nitrogenous, phosphorus flame-retardant system is as a kind of new Green Flammability system, have
Higher flame retarding efficiency, is the major trend replacing bromine-containing compound at present.In addition, PBT is (poly-
Mutual-phenenyl two acid bromide two alcohol ester) there is the characteristic that height is heat-resisting, high intensity, resistance to ag(e)ing are good, and
Price is relatively low, is also the wide engineering plastics of application, but its toughness is poor, processing fluidity
Bad, surface property is bad, due to PBT and ABS poor compatibility, physical performance is blended merely
Difference, particularly impact flexibility low it is therefore desirable to increase-volume and toughness reinforcing.
Flame-retardant PBT/ABS alloy material of the prior art, or not being halogen-free environment-friendly flame-proof,
It is that impact flexibility is relatively low, or being that mobility is bad, range of application is not extensive.
