NOVELTY - High thermal conductivity press card plastic crystal composite material comprises graphene powder and plastic crystal material. USE - High thermal conductivity press card plastic crystal composite material. ADVANTAGE - The high thermal conductivity press card plastic crystal composite material improves the thermal conductivity of the press card plastic crystal. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: 1. a method for preparing a high thermal conductivity press card plastic crystal composite material, which involves: a. weighing out the corresponding mass of graphene powder and plastic crystal material; b. mixing the two materials and grinding them thoroughly, then pouring the fully mixed and uniform sample into the mold, and using a hydraulic press to form by cold pressing; and 2. a method for increasing the thermal conductivity of a press card plastic crystal material, which involves: mixing plastic crystal material and the graphene powder in a certain mass ratio and pressed into shape.
