[0003] The current traditional technology is mainly mature in gasoline resistance. Traditional automobile pipelines generally use EPDM (ethylene-propylene rubber, a copolymer of ethylene, propylene and a small amount of non-conjugated dienes). This material is widely used in the market and is used in gasoline-resistant It has good characteristics, but it has insufficient resistance to methanol, so it cannot be used in the oil pipeline of methanol vehicles.
At the same time, due to the small application and market scale of methanol, no relevant companies have carried out special research on methanol fuel storage and flow pipeline materials.

Abstract
The invention provides a plastic composition resistant to a methanol fuel and gasoline, and relates to the technical fields of vehicle material compositions and production. The composition includes abasic rubber variety, an additive and an anti-aging agent; and the composition concretely comprises the following materials in parts by weight: 50-80 parts of acrylonitrile-butadiene rubber, 20-40 parts of polyvinyl chloride (PVC), 3-6 parts of zincoxide, 1-3 parts of stearic acid, 0.5-2 parts of sulphur, 1-3 parts of anti-ozonewax, 0.5 part of di-sec-octyl phthalate, 30-50 parts of carbon blackN774 (N774), 20-30 parts of carbon black N330 (N330), 20 parts of bariumsulfate, 5-7 parts of liquid butyronitrile, and 3-8 parts of the anti-aging agent. The invention also provides a preparation method of the plastic composition. According to the method provided by the invention, the plastic composition is prepared by co-mixing of the acrylonitrile-butadiene rubber and the polyvinyl chloride,and has the advantages of excellent aging resistance, oil resistance, solvent resistance and chemical corrosion resistance, and additives such as the zincoxide and the anti-aging agent are added, sothat the material can have corrosion resistance to methanol and gasoline after being shaped.
Description
technical field [0001] The invention relates to the field of vehicle material composition and production technology, in particular to a plastic composition resistant to methanol fuel and gasoline and a preparation method thereof. Background technique [0002] As the degree of industrialization of human life is getting higher and higher, the reliability development of automobiles is also becoming more and more sound. At the same time, with the popularization of methanol vehicles and the development of development and verification, in order to meet the special requirements of methanol vehicles for methanol and gasoline resistance, it is more and more important to develop materials resistant to methanol and gasoline. [0003] The current traditional technology is mainly mature in gasoline resistance. Traditional automobile pipelines generally use EPDM (ethylene-propylene rubber, a copolymer of ethylene, propylene and a small amount of non-conjugated dienes). This material is wi...
