▎ 摘　　要

NOVELTY - High thermal conductivity reinforced polyphenylene sulfide composite material comprises 30-50% polyphenylene sulfide substrate, 5-30% surface carbonization reinforcement and 20-60% thermally conductive filler. The surface carbonization reinforcement is a reinforcement whose outer surface is coated with a carbon layer. USE - Used as high thermal conductivity reinforced polyphenylene sulfide composite material. ADVANTAGE - The material significantly improves the thermal conductivity of the polyphenylene sulfide composite material and ensures excellent processing performance and mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the material, comprising (i) blending the monomer raw materials, the reinforcement and the optional two-dimensional sheet-shaped thermally conductive filler, and obtaining the surface carbonization reinforcement after in-situ polymerization and carbonization; and (ii) using the polyphenylene sulfide substrate, the thermally conductive filler and the surface carbonized reinforcement prepared in the step (i) as raw materials and performing extrusion granulation.
