Abstract

The invention provides modified automobile engineering plastic and a preparation method thereof, and relates to the technical field of plastic materials. The modified automobile engineering plastic isprepared from the following raw materials: modified nylon, PVC resin, ceramic powder, polytetrafluoroethylene micro powder, carbon black, hexamethylphosphoramide, an antioxidant, a compatilizer, a flexibilizer, a lubricant, an aluminate coupling agent and a dispersant. The modified automobile engineering plastic has high impact property and abrasion resistance, not only has excellent mechanical properties, but also improves the weather fastness and heat resistance of the materials, and has excellent water resistance and steam resistance, a product has high tensile strength and impact strength, and further has the advantage that the product is not shrunk and not embrittled in low temperature environment.

Description

technical field [0001] The invention relates to the technical field of plastic materials, in particular to a modified automotive engineering plastic and a preparation method thereof. Background technique [0002] The automobile industry is one of the important basic industries in the national economy. The development of the automobile industry will drive the development of metallurgy, petrochemicals, light industry, textiles, electronic appliances, machinery, building materials and road construction. The development level of the automobile industry is a measure of a country's One of the important symbols of economic strength. Replacing steel with plastic, energy saving and emission reduction, green environmental protection, and automobile lightweight are the top priorities in the automotive industry. At present, a large number of plastics have been used to replace various non-ferrous metals and alloy steels. [0003] With the rise of automobile lightweight, the use of autom...
