Abstract

The invention discloses a preparation method of a wear-resistant composite material for a fender. The preparation method comprises the steps that raw materials are fed in parts by weight into a high-speed stirring machine for stirring, then the stirred materials are subjected to melting extrusion in a twin-screw extruder, an extruded product is cooled and granulated by a granulator, granules are dried, screened and packaged, and a product is obtained. The wear-resistant composite material for the fender has the advantages of light mass, high strength, impact resistance, good damping effect and the like, and is greatly superior to most products in the market especially in the aspect of wear resistance; when the composite material is used for producing the fender, light weight of an automobile, energy saving and environmental protection are realized, the composite material further has the advantages of low cost and simple process, and large-scale popularization and application are facilitated.

Description

technical field [0001] The invention belongs to the field of polymer materials and relates to a preparation method of a wear-resistant composite material for fenders. technical background [0002] As the name suggests, the car fender is the function of mudguard. The fender is a plate structure installed behind the outer frame of the wheel. It is usually made of high-quality rubber material, and engineering plastics are also used. There is no doubt that the fender can effectively prevent the paint surface of the car body from being damaged by flying stones and gravel, and protect the car body surface from being scratched. In addition, the function of the car fender is to increase the overall aesthetics of the car body. This is also the reason why many car owners install car fenders. In addition, it can prevent some mud from splashing on the vehicle body or the person, causing the vehicle body or the person to be unsightly, and it can also prevent the mud from splashing on t...
