Thermoplastic special engineering plastic PPS/PI alloy material and preparation method thereof

Abstract

The present invention belongs to the technical field of synthetic materials, specifically a thermoplastic special engineering plastic PPS/PI alloy material and preparation method thereof, ingredients of the alloy material include: PPS 75-85 parts, PI 10-20 part, activated alumina 10-15 parts, polyfluortetraethylene 0.2-0.5 part; the activated alumina is prepared with aluminum oxide and epoxy-containing silane coupling agents; a preparation method of the alloy material is: mixing the PPS, the PI, the activated alumina and the polyfluortetraethylene at an atmospheric temperature high-speed mixer, extruding and pelletizing the same with a twin-screw extruder and the thermoplastic special engineering plastic PPS/PI alloy material can be obtained. The alloy material has improved wear resistance performance, good high temperature resistance properties, can be used repeatedly and is a kind of environmental-friendly material.
