Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a graphene chemical-resistant weather-resistant thermally conductive plastic and a preparation method thereof. Background technique [0002] Plastic is a polymer compound (macromolecules) that is polymerized by addition or polycondensation of monomers, commonly known as plastics or resins. It can freely change its composition and shape. It is composed of synthetic resins and fillers, Plasticizer, stabilizer, lubricant, colorant and other additives. The main component of plastic is resin. The term resin was originally named after the lipids secreted by animals and plants, such as rosin, shellac, etc. Resin refers to a polymer compound that has not been mixed with various additives. Resin accounts for about 40% to 100% of the total weight of plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an import...
