Abstract

The invention relates to a scratch-resistant and high-transparent polycarbonate composite material and a preparation method thereof. The scratch-resistant and high-transparent polycarbonate compositematerial comprises the following raw material components in part by weight: 80-100 parts of polycarbonate, 10-20 parts of flame retardant, 10-20 parts of scratch-resistant agent, 10-15 parts of filler, 0.5-1 part of dispersant and 0.2-1 part of anti-dripping agent. According to the scratch-resistant and high-transparent polycarbonate composite material and the preparation method thereof, by addinga nano-wire with a large length-diameter ratio as the scratch-resistant agent, the influence on the transparency of polycarbonate can be reduced; the prepared polycarbonate composite material has good scratch-resistant effect and good transparency and good material safety, meanwhile, the wear resistance and mechanical property are improved, the scratch-resistant and high-transparent polycarbonatecomposite material can be widely used in the fields of home appliances, automobiles and electronic equipment. When the scratch-resistant and high-transparent polycarbonate composite material is prepared by the invention, twin-screw extrusion equipment is adopted, the flow process is simple and continuous, and the obtained product is stable in quality.

Description

technical field [0001] The invention relates to the technical field of polycarbonate composite materials, in particular to a scratch-resistant highly transparent polycarbonate composite material and a preparation method thereof. Background technique [0002] Polycarbonate is a thermoplastic engineering plastic with superior comprehensive performance developed in the 1950s. It has high impact resistance, high toughness, high heat resistance, weather resistance and excellent electrical insulation. It is the only one of the five major engineering plastics with Transparent plastic products are known as transparent metals. Widely used in the automotive industry, instrumentation, electronic appliances and other fields. Most of the home appliances we use today, such as TVs, refrigerators, washing machines, water dispensers, etc., are also widely used in polycarbonate plastics. [0003] At present, bisphenol A polycarbonate is the most widely used commercially, but the surface scr...
