Abstract

The invention provides special regenerated modified plastic particles for an automobile and a preparation method. The regenerated modified plastic particles are prepared from the following componentsin parts by weight: 50 to 70 parts of waste ABS (Acrylonitrile Butadiene Styrene) plastic, 50 to 75 parts of waste PC (Polycarbonate) plastic, 10 to 25 parts of an auxiliary material, 10 to 26 parts of a polypropylene compound and 10 to 24 parts of an additive; the auxiliary material comprises waste tire plastic and fiber yarns; the additive is prepared from 1 to 4 parts of a flame retardant, 1 to6 parts of a compatibilizer, 0.1 to 1 part of a lubricant, 0.6 to 3 parts of a plasticizer, 0.1 to 6 parts of an antioxidant, 8 to 20 parts of the waste tire plastic and 2 to 5 parts of the fiber yarns. According to the technical scheme provided by the invention, the regenerated modified plastic particles are prepared by regenerating the waste ABS plastic, the waste PC plastic, the waste tire plastic and the fiber yarns; when the waste plastic is reutilized and plastic pollution is reduced, the newly-obtained regenerated plastic particles have better toughness and flame-retarding performance.

Description

technical field [0001] The invention relates to the field of regeneration and remodeling of waste plastics, in particular to a special recycled and modified plastic particle for automobiles and a preparation method thereof. Background technique [0002] Plastic ABS resin is currently the polymer with the largest output and the most widely used. It organically unifies the various properties of PB, PAN, and PS, and has excellent mechanical properties of toughness, hardness, and rigid phase balance. ABS is a terpolymer of acrylonitrile, butadiene and styrene, A stands for acrylonitrile, B stands for butadiene, and S stands for styrene. After actual use, it was found that: ABS plastic pipes are not resistant to sulfuric acid corrosion, and will be shattered and broken when encountering sulfuric acid. However, when it is widely used, the amount of waste ABS plastic produced every year is quite large, which is not convenient for environmental protection. [0003] Most of ABS is ...
