Abstract

The invention discloses a commercial vehicle recycled modified fender material and a preparation method thereof. The material is prepared from, by weight, 30%-58% of polypropylene reclaimed materials, 20%-40% of reclaimed toughening agent, 20%-30% of mineral powder, 0.1%-0.5% of antioxidant, 0.1%-0.5% parts of light stabilizer and 0.1%-0.5% of ultraviolet absorbent. According to the commercial vehicle recycled modified fender material and the preparation method thereof, the polypropylene reclaimed materials and waste film materials serve as raw materials for preparation, and the current reuse problem of the waste materials is well solved; meanwhile, the production cost of the fender is saved, the reclaimed materials are subjected to purification, cleaning, drying, homogenization and regeneration, and the stable use performance is achieved. A hindered amine light stabilizer is adopted, a light and oxygen degradation reaction is inhibited through various paths of capturing free radicals, resolving hydroperoxide, delivering excited molecule energy and the like; a benzotriazole ultraviolet absorbent and the hindered amine light stabilizer are used together, the synergistic effect is achieved, and the anti-aging capacity of the material can be improved by 2-4 times.

Description

technical field [0001] The invention relates to a preparation material for auto parts and a preparation method thereof, in particular to a commercial vehicle regeneration modified fender material and a preparation method thereof. Background technique [0002] Car fenders, as the name suggests, play the role of mudguards. When cars (especially large trucks and commercial vehicles, etc.) are driving on water-logged roads, they will splash water and produce splashes, which will damage the driver and the road. Therefore, its function is to reduce the damage to the car caused by the water mist, sand and other splashes splashed by the car tires in motion, and guide the collected water mist, sand and other splashes to the ground , to prevent mud from splashing on the tie rod and the ball head and causing premature rusting. Due to the special conditions of use of the fender, its preparation materials must meet the following conditions: [0003] (1) The fender of the car is located...
