Abstract

The invention discloses a preparation method of an environment-friendly composite engineering plastic, which uses recycled polyvinyl chloride material, dipropylene phthalate and polyvinyl ester elastomer to make a composite engineering plastic masterbatch, which has excellent impact toughness , and reduce the cost; highly dispersed nano-calcium carbonate and composite engineering plastic masterbatch have good dispersion and compatibility, improve the fluidity and processing performance of composite engineering plastic masterbatch, and endow engineering plastics with better physical and mechanical properties , to further improve the toughness; flame-retardant materials such as graphene, titanium dioxide, and halloysite nanotubes in the modified anti-aging flame-retardant system and anti-aging materials such as wollastonite needle-like fibers form a composite synergistic effect, which greatly improves the engineering quality. Flame retardant and anti-aging properties of plastics; no secondary pollution, clean and civilized production, less labor, high labor efficiency, energy saving, and environmental protection.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, in particular to a preparation method of environment-friendly composite engineering plastics. Background technique [0002] While engineering plastics satisfy people's life and social development, the social and environmental problems caused by the "white pollution" caused by the sharp increase of plastic waste are also becoming more and more serious. Recycled engineering plastics is an effective way to solve the pollution caused by engineering plastics, but recycled engineering plastics have disadvantages such as low strength, no toughness, low gloss, and poor thermal oxygen stability. In addition, due to the macromolecular chain of recycled engineering plastics There are tertiary carbon atoms. During storage, processing and daily use, they are prone to aging and degradation due to the effects of heat, light and oxygen. The weather resistance is extremely poor, which seriously affec...
