▎ 摘　　要

NOVELTY - Preparing heat-conducting engineering plastic involves carboxylation treatment, pretreatment, sintering, ionization, drying, ball milling, hydrogel preparation, aerogel preparation and finished products. USE - Method for preparing heat-conducting engineering plastic. ADVANTAGE - The method enables to reduce the amount of plastic between the thermally conductive particles and increase the bonding between the filler and the matrix, reduce the thermal resistance of the body itself, and also improve the thermal conductivity of thermally conductive engineering plastics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a heat-conducting engineering plastic, which comprises 100-130 pts. wt. plastic matrix, 15-20 pts. wt. modified graphene aerogel, 25-30 pts. wt. copper powder and magnesium oxide powder mixed material, where the plastic matrix is liquid resin.
