Description

technical field [0001] The invention relates to a plastic, in particular to a polyetheretherketone heat-conducting composite material and a preparation method thereof, belonging to the technical field of plastics. Background technique [0002] Plastic is a very important organic synthetic polymer material with a wide range of applications. Plastics are formulated from many materials, among which high molecular polymers, also known as synthetic resins, are the main components of plastics. In addition, in order to improve the performance of plastics, various auxiliary materials must be added to high molecular compounds, such as fillers, extenders, etc. Plasticizers, lubricants, stabilizers, colorants, antistatic agents, etc., can become plastics with good performance. my country is a big producer of plastic raw materials. As one of the pillar industries of the light industry, the plastic industry has always maintained a relatively fast development speed, and at the same time,...
