Problems solved by technology

However, the mechanical properties of polycarbonate are not high, the hardness is not ideal when used, and its heat resistance is not good. Although it has a certain flame retardancy, it often cannot meet the requirements of occasions with high flame retardancy requirements. , usually requires special treatment of polycarbonate products, which severely limits its application

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a polycarbonate composite material with high hardness and high flame retardancy. Background technique [0002] Polycarbonate is a high molecular polymer containing carbonate groups in its molecular chain. It has the advantages of high impact strength, wide temperature range, good fatigue resistance, tasteless and odorless, etc. It is currently the largest production scale and the most widely used. As one of the most widely used thermoplastic engineering plastics, it has been widely used in glass assembly industry, automobile industry, electronic and electrical industry, medical care, office equipment and other fields. However, the mechanical properties of polycarbonate are not high, the hardness is not ideal when used, and its heat resistance is not good. Although it has a certain flame retardancy, it often cannot meet the requirements of occasions with high flame ret...
