Abstract

The invention relates to preparation of a car fender and particularly relates to a fender for a waste rubber powder car and a preparation method of the fender. The method comprises the following steps: carrying out blending extrusion, granulating and drying on undesulfured waste rubber powder, polyolefin, chlorinated polyethylene, a compatilizer, a flow modifier 1 and a flow modifier 2; melting obtained particles to embed into an enhancement layer until the molten resin is molded to obtain an intermediate layer of the car fender; and combining an outer layer and an inner layer with the intermediate layer by adopting a hot laminating mode to obtain the fender for the waste rubber powder car.

Description

technical field [0001] The invention relates to the preparation of a vehicle fender, in particular to a waste rubber powder vehicle fender and a preparation method thereof. Background technique [0002] The car fender can effectively protect the car body when the car is running, and reduce the damage to the car caused by the crushed stones on the road flying out due to the rolling of the wheels. At present, the main materials of vehicle fenders are mainly plastics such as PPT and ABS, but the hardness of plastics is relatively high, and they are prone to damage when subjected to external impact, and their service life is short in high temperature and severe cold environments. Therefore, in order to improve the cost performance of the fender, the fender made of rubber has become a development trend. The texture of the rubber is soft, the elasticity is good, and it can be bent at will without deformation. , The service life is as high as 3 to 5 years. But the cost of the veh...
