Description
Technical field
The invention belongs to polymeric material field, relate to a kind of preparation method of fuel tank of vehicle POM plastic particle.
Technical background
Engineering plastics can be made engineering materials and replace metal to manufacture the plastics of element part etc.The performance characteristics of engineering plastics is mainly:
(1) compared with general-purpose plastics, there is excellent heat-resisting and cold tolerance, good mechanical performance in temperature range widely, suitablely to use as structured material;
(2) erosion resistance is good, affected by environment less, has good weather resistance;
(3) compared with metallic substance, easily process, production efficiency is high, and can simplify procedures, cost saving;
(4) good dimensional stability and electrical insulating property is had;
(5) lightweight, specific tenacity is high, and has outstanding antifriction, wear resistance.
At present, engineering plastics are because of the stability of its excellence, good heat-resisting and chemical resistant properties and high strength, and Application Areas is extensive, and its demand maintains sustained and rapid growth.One of main application of engineering plastics is the application of alternative metals in various terminal industry.Particularly the environmental regulation of increasingly stringent requires automobile emissions reduction amount and improves fuel economy, and engineering plastics are just being widely used in automobile and carrier.
Along with the development of automotive industry, the application of engineering plastics also will be more and more extensive; Fuel tank of vehicle is one of function part and safety member important in trolley part, and traditional fuel tank metal makes, due to the singularity of intermetallic composite coating, shaping more difficult, and the intensity at soldered place is also low, and production qualification rate is lower.Relative to traditional metal fuel tank, Engineering Plastic Fuel Tank then has the following advantages: the molding processibility of (1) plastics is good, easy scale production; (2) plastics have fabulous chemical resistance, and plastic fuel tank has the erosion action the trouble of removing maintenance from of resisting water, dirt and other media; (3) weight of plastic fuel tank comparatively metal light, plastics relative density is only 1/8 ~ 1/7 of metal, so compared with the metal fuel tank of same volume, its weight can reduce greatly, thus is conducive to alleviating car weight, improves the speed of a motor vehicle, fuel saving; (4) plastic fuel tank freedom of design in configuration is large, and space availability ratio is high, can be processed into various complicated shape, is conducive to the space making full use of car body, thus can increase the weight-carrying capacity of fuel oil, improves the steaming range of automobile.So, use Engineering Plastic Fuel Tank to replace traditional metal fuel tank to be inevitable trend.Polyoxymethylene (POM) is that one uses engineering plastic resin widely.There is the title of " taking steel by force ", " supersteel " abroad.POM has the hardness of metalloid, intensity and rigidity, within the scope of very wide temperature and humidity, all have good self lubricity, good resistance to fatigue, and springiness, it also has good chemical-resistant in addition.The fuel tank of the automobile that can make of polyoxymethylene (POM).Therefore people add various filler or auxiliary agent carries out modification in engineering plastics, but many modified effects are unsatisfactory.For this reason, we set about from the formula of product, develop new H.D starting material, provide a kind of polyoxymethylene (POM) plastic pellet that can be used for obtained high performance plastic fuel tank.
