Description
Technical field
The invention belongs to polymeric material field, relate to a kind of polypropylene material, be specifically related to one can realize lightweight,
The fretting map of environmental protection and metal effect exempts from spray coating polypropylene material and preparation method thereof.
Background technology
In recent years, along with improving constantly of living standards of the people, automobile volume of production and marketing keeps quick growth always, and along with oil is constantly consumed, energy dilemma is more and more serious, and automotive light weight technology has become the inexorable trend of development of automobile industry.Automotive light weight technology not only can reduce tare, reduces automobile making production cost, reduces terminal consumer's fuel oil consumption, can also reduce exhaust emissions, alleviate environmental pollution.In auto plastics, modified polypropylene material is the maximum class material of consumption always, and car trim is substantially to spray paint, and whole spraying process process procedure is complicated, and technology controlling and process is difficult.Simultaneously, paint is containing volatile organic solvent, and these volatile organic solvents contain certain poisonous and harmful substances, therefore, whole link of spraying paint can have a strong impact on the healthy of workman and environmental pollution, does not meet environmental protection and the Sustainable development of whole industry.
Current; the lightweight of automotive material, environmental protection more and more become one of most important problem of whole automobile industry; micro-foaming polypropylene material has fine and close top layer and foam core structure; can ensure under the prerequisite that material fundamental property is not lost; significantly alleviate the weight of product, thus effectively realize the lightweight of automobile.Have in the market about alternative spraying exempt from spray
Be coated with the report of polypropylene material, but, in the market also not about both can lightweight be realized, can environmental protection be realized again, and there is the report of exempting from spray coating polypropylene material of metal effect.Because fretting map technology is also in the technological development stage, is not also widely used in market, meanwhile, fretting map exempts from a spray coating polypropylene material technology brand-new problem especially.Therefore can realize lightweight, the fretting map of environmental protection and metal effect exempts from the inexorable trend that spray coating polypropylene material will be the industry such as future automobile, household electrical appliances plastic decorating part Materials.
