Description

technical field [0001] The invention belongs to the field of plastic materials, and in particular relates to a heat-conducting and wear-resistant plastic material and a preparation method thereof. Background technique [0002] Thermally conductive materials are widely used in LED lighting industry, heat exchange engineering, heating engineering and electronic information engineering. Usually, traditional heat-conducting materials are mostly metal materials such as copper and aluminum. However, although metal materials can conduct electricity, they have disadvantages in corrosion resistance and other properties, which also limit their application in the field of heat conduction. Nowadays, plastic materials have greatly improved in terms of comprehensive performance, such as corrosion resistance, impact resistance and strength resistance. Lightweight, corrosion-resistant, wear-resistant, and easy-to-form plastic materials have gradually become the focus of attention. With th...
