Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an antistatic refractory composite material, a preparation method thereof and semiconductor equipment. Background technique [0002] Polymer material refers to a high molecular weight (usually up to 10-10 6 ) compounds. Polymer materials are widely used in daily life due to their wide sources, corrosion resistance, and strong plasticity. However, polymers are flammable and produce toxic gases when burned, which is a potential fire safety hazard. At the same time, most polymers are insulators, which are prone to static electricity during friction, thus limiting their application in the anti-static industry. Therefore, it is very necessary to study a composite material with excellent fireproof performance and antistatic performance. [0003] In view of this, the present invention is proposed to solve at least one of the above technical problems. Contents of the inv...
