Abstract
The present invention relates to a formula for a car wheel guard of ethene-vinyl acetate copolymers (EVA), which is EVA resin, high-pressure polyethylene, low-pressure polyethylene and carbon black. The present invention has the advantages that compared with the ordinary rubber material, the adopted new modified plastic material has the characteristics of aging resistance and low temperature resistance.
Description
The invention belongs to the automobile fender, particularly a kind of is the automobile fender of material with ethylene-vinyl acetate copolymer (EVA).
At present China's automobile adopts HG4-543 II group General Purpose Rubber material to make with fender mostly, and the high aging resistance of this material fragility temperature is poor, and work-ing life is low, often sees the phenomenon that stone that the automobile fender that uses 1-2 taken up by wheel breaks.
The purpose of this invention is to provide the automobile fender of a kind of ethylene-vinyl acetate copolymer (EVA) material, overcome above-mentioned shortcoming and defect.
The object of the present invention is achieved like this:
A kind of automobile fender of ethylene-vinyl acetate copolymer material, it consists of: ethylene-vinyl acetate copolymer resin, high-pressure polyethylene, low pressure polyethylene and carbon black.
Its proportion of composing is: ethylene-vinyl acetate copolymer resin portions of resin high-pressure polyethylene: low pressure polyethylene: carbon black is 10: 4: 1: 0.02.
Its automobile fender manufacture craft flow process is as follows: batching → mixing → granulation → bundle prolongs → cuts material → moulding.
Advantage of the present invention is:
The automobile fender of ethylene-vinyl acetate copolymer (EVA) material adopts is that a kind of novel modified plastic material is compared with the General Purpose Rubber material and had anti-aging low temperature resistant characteristics, adopts HG4-543 II group General Purpose Rubber material as follows with the contrast properties of modified EVA automobile usefulness fender material:
Standard of performance HG4-543 II group

* 96 hours) be not less than 1.12
This project is mainly Tianjin Xiali, big sends out, 1041 automobiles, prosperous river automobile etc. are supporting, and this project belongs to domestic initiation, substitutes import, has filled up domestic blank, classifies the Spark Plan project in 93 years as for the Municipal Commission of Science and Technology.
The economic benefit of this generation: the end of the year output value/ten thousand yuan profits tax/ten thousand yuan save foreign exchange/ten thousand yuan 94 640 168 7,595 1,440 369 16,996 1,660 425 195
Along with the development of Domestic Automotive Industry, these project market outlook are wide, and considerable economic and social benefit are arranged.
