Description
Technical field
The present invention relates to a kind of automobile-used low ABS of distributing composition and method of making the same, be mainly used in automobile industry.
Background technology
ABS(acrylonitrile-butadiene-styrene) resin is the thermoplastic engineering plastic of a kind of novel universal of the exploitation forties in 20th century.ABS material is acrylonitrile-butadiene-styrene terpolymer, because ABS resin has been coordinated the high-performance of three kinds of components, so there is good resistance to impact shock, good processing characteristics and chemical stability, be easy to molded, goods are rich in gloss, and have toughness and flexibility concurrently, high comprehensive performance.ABS resin is widely used in the industries such as automotive industry, electronic apparatus industry, light industry household electrical appliances, weaving and building with its remarkable over-all properties.In recent years, automobile industry is more and more higher to the requirement of the emission characteristics of automotive interior material.Compartment is because often meeting is in closed state, and the materials such as its leather, plastics, glue can produce a lot of sporadic organic compound, as aldehydes, alkane, benzene, toluene etc.These materials can be known from experience generation detrimentally affect to people.To these a lot of automobile factorys, for reducing the content of sporadic material in material, require starting material producer to control the emission characteristics of various types of materials.
The production method of ABS resin is a lot, and applying on full scale plant in the world at present more is that emulsion connects skill fusion method and continuous bulk.The ABS emission characteristics that wherein continuous bulk is produced is relatively better.But also still can not meet the requirement of automobile main frame maker.Main chemical physics adsorption both at home and abroad at present reduces the sporadic material of material, and palladium doped molecular sieve adsorbs VOC gas, and this molecular sieve is adsorb volatile gas long-term effectively, is a kind of effective VOC remover; Small molecules when Chinese patent CN10134658A carrys out absorption reaction with a kind of activated alumina.The small molecules that patent CN101469122A and CN1730543A produce while all carrying out absorption reaction with hydrophobic molecule sieve material.Yet the method that reduces sporadic material by chemical reaction, often only for a factor, can not solve the sporadic problem that various factors produces simultaneously; Physical adsorption does not possess specific selectivity, can adsorb the small molecules of all generations.As some functional aids in formula are also likely adsorbed in the course of processing, affect the long-term ageing property of polymkeric substance.In addition, the material of molecular sieve adsorption still exists in system, under long-term thermal ageing, photoaging effect, has the risk again discharging.Another is exactly the mode of the physics oven dry of a lot of manufacturers use, and the mode of expecting by baking is gone out the bakings such as small molecules.Not only efficiency is low for this method, operability is poor, and can not thoroughly improve the VOC emission characteristics of material.
