Abstract

The invention discloses a wear-resistant regenerated PC / POK alloy material and its preparation method and application. The material comprises, by mass, 70 to 90% of regenerated polycarbonate (PC), 5 to 20% of polyketone (POK), 2 to 5% of a compatibilizer, 2 to 5% of a flame retardant, 0.3 to 2% of an antioxidant and 0.4 to 2% of a lubricant. The material has excellent impact toughness, good flame retardant properties, good electrical insulation properties and good wear resistance and is very suitable for preparation of a scratch-resistant exterior part. The preparation method utilizes the existing equipment, has simple processes, is suitable for industrial production and has a wide application prospect and environment friendliness.

Description

technical field [0001] The invention relates to the technical field of recycled polycarbonate composite materials, in particular to a wear-resistant recycled PC / POK alloy material and its preparation method and application. Background technique [0002] PC (polycarbonate) is an almost colorless glassy amorphous polymer with good optical properties. As an engineering plastic with superior comprehensive performance, PC has excellent impact toughness, good dimensional stability and electrical insulation. With the rapid expansion of usage and application scope, discarded plastic products have also brought great negative effects on the environment. [0003] As an amorphous thermoplastic resin with excellent comprehensive properties, polycarbonate is second only to polyamide in engineering plastics, and is often used to make high-gloss components such as wall switches and switch panels. Due to the long-term use and aging of waste polycarbonate materials, their physical and mecha...
