Problems solved by technology

Plastic fenders are brittle and prone to breakage during use. If the chassis of the car is low, it is easy to drop or scratch the body when scratching hard objects; while rubber fenders have good softness and impact resistance capacity, but rubber fenders are more expensive than plastic

Abstract

The invention discloses an automobile fender material. The automobile fender material is prepared from waste tires, crude chloroprene rubber, polyethylene resin, molybdenum disulfide, sericite powder, oleic acid, silicon oil, a dispersing agent, 2-(2'-hydroxy-3'5'-ditert-phenyl)-5-benzotriazole chloride, 4-benzoyloxy-2,2,6,6-tetramethylpiperidine, an anti-aging agent and a vulcanizing agent. The preparation method includes steps of pretreatment of waste tires and polyethylene resin, plastication of crude chloroprene rubber, mixing of auxiliary agents, thermal forming of rubber materials, demoulding and twice vulcanization. The automobile fender material has advantages of extensive raw material sources, cheap raw materials, reasonable ratio, low production cost, excellent flexibility, impact resistance, abrasion resistance and aging resistance and less proneness to breakage, and a preparation process is simple, low in energy consumption and high in repetition rate.

Description

technical field [0001] The invention relates to the technical field of automobile parts materials, in particular to an automobile fender material and a preparation method thereof. Background technique [0002] Automobile fenders are one of the most important parts in the composition of automobiles. When the automobile is running on a muddy road, it can prevent the mud from splashing on the body or pedestrians around it. Parts cause premature rusting of parts, which indirectly affects the service life of other parts, and the fenders used on the car can also avoid damage to the exterior paint of the car caused by small stones entrained in the tire seams. Therefore, automobile fender is an indispensable part in the process of automobile production and assembly. [0003] There are two main types of car fender materials currently available on the market: rubber and plastic. Plastic fenders are brittle and prone to breakage during use. If the chassis of the car is low, it is eas...
