Description

A kind of automobile-used ABS plastic alloy material and preparation method thereof
Technical field
The application belongs to plastic alloy material field, relates in particular to a kind of automobile-used ABS plastic alloy material and preparation method thereof.
Background technology
Plastic alloy is to utilize the method for physical blending or chemical graft and a class new material of the high-performance that obtains, functionalization, customizations. Plastic alloy product can be widely used in the fields such as automobile, electronics, precision instrument, office equipment, packaging material, construction material. It can improve or improve the performance of existing plastics and reduce costs, and has become one of kind the most active in plastics industry, increases very rapid. China's plastic industry will be got a clear understanding of the situation, and finds gap accurately, seizes the opportunity, and strengthens input in science and technology, accelerates development Plastics Industry, the world development level of emulating.
General-purpose plastics alloy, if pvc (polyvinyl chloride), TLCP (polyethylene), EPDM (polypropylene), alkyl first diphenyl phosphite (polystyrene) are although alloy still has use value widely, but because its production technology is generally grasped, so abroad, each major company specialize in supply be mostly the engineering plastic alloy kind that added value is higher. The blend of engineering plastic alloy general reference engineering plastics (resin), mainly comprise the co-mixing system taking engineering plastics such as SMA, SMA, PA, POM (polyformaldehyde), EPDMO, PTFE (polytetrafluoroethylene (PTFE)) as main body, and DCP resin modified material.
SMA/DCP resin, Merlon and acrylonitrile-butadiene-styrene copolymer and mixture, it is the thermoplastic plastic rubber being formed by Merlon (Polycarbonate) and polyacrylonitrile (DCP) alloy, combine the excellent specific property of bi-material, the character such as the mouldability of DCP material and the mechanicalness of SMA, impact strength and heatproof, uvioresistant (UV), can be widely used on automotive interior parts, business machine, the communication apparatus, electrical home appliances and lighting apparatus.
The maximum user of world's plastic alloy product is automobile component at present, is secondly machinery and electronic devices and components. From Japanese major project plastic alloy demand structure, can find out, automotive plastic alloy accounts for 62%, and electric and business automation equipment accounts for 20%, and general precision optical machinery accounts for 6%, and medical treatment, physical culture and other account for 12%. From area, North America is maximum plastic alloy consumption area at present, accounts for 45%; Next is Europe, accounts for 34%; The Asia-pacific region accounts for 21%. In North America, EPDMO(polyphenylene oxide) alloy accounts for the more than 25% of plastic alloy total demand, wherein especially with EPDMO/PA(SMA), the having the call of EPDMO/SMA (PETG) and EPDMO/SMA (polybutylene terephthalate (PBT)) alloy; SMA (Merlon) alloy accounts for the more than 12% of aggregate demand; DCP alloy for automobile final use accounts for 99%.
China is to the research of plastic alloy since the sixties in 20th century, and development was very fast in recent years. According to statistics, at present China's plastic alloy (containing modified resin) total quantity consumed is about 1,200,000～1,400,000 tons, and 600,000 tons of domestic supply quantity not sufficients, annual import volume is up to 900,000 tons of left and right; And China's plastic alloy (being mainly blending resin and modified resin) is mainly used in household electrical appliances, electronics, automobile and other industries, compared with developed countries, the plastic alloy application market of China also has very large expanding space.
Along with China's sustained and rapid development of economy, a few years from now on China plastic alloy market demand potential is huge, and the especially rapid growth of telecommunications, automobile, building industry will pull China's engineering plastic alloy industry fast development. Expect 2008, China's five large-engineering plastics aggregate demands will reach 1,000,000 tons, and the demand of five large synthetic resin will reach 5,200 ten thousand tons, will become one of importer of global plastic alloy maximum.
ABS has good comprehensive physical and mechanical performance, fabulous low-temperature impact resistance. Dimensional stability. Electrical property, wearability, chemical proof, dyeability, finished product processing and machining are better. ABS resin is water-fast, inorganic salts, alkali and acids, is insoluble to most of alcohols and varsol, and is easily dissolved in aldehyde, ketone, ester and some chlorohydrocarbon. ABS resin heat distortion temperature is low flammable, and weatherability is poor. Melt temperature is at 217 ~ 237 DEG C, and heat decomposition temperature is more than 250 DEG C. Modified ABS material on market of today is all much adulterated regrinding-material, reworked material. Cause client's shaped article performance to differ and unstable.
At present, China plastic alloy research and produce all states in fragmentary dispersion also of two aspects, not yet forms scale, and industry integral level is low, differs greatly with Foreign Advanced Lerel. In Plastics in China alloy production breed structure, the production of the special engineering plastics alloy of high added value, almost in blank, is the production of general-purpose plastics alloy and modified product substantially. Existing 300 Duo Jia plastic alloy manufacturing enterprises of China in 2004, estimate that plastic alloy (containing modification pellet) production capacity is 700,000～800,000 tons/year, and output is 600,000 tons/year of left and right. But wherein larger enterprise only accounts for 15%, and this enterprise production of 15% accounts for the more than 70% of national plastic alloy total output. Enterprise's major part is to produce the Processing Firm of plastic alloy by plastic milling expressing technique. China's plastic alloy research and development and processing technology level have much room for improvement. And universal along with humanity concept, and the formation of novel harmonious society, designs that a kind of intensity is high, impact-resistant automobile-used ABS plastic alloy material and preparation method thereof is very important.
