Description

technical field [0001] The invention belongs to the field of electrical insulating materials, in particular to a wear-resistant polycarbonate-based electrical insulating material and a preparation method thereof. Background technique [0002] Due to its good flame retardancy and dimensional stability, polycarbonate has formed a broad application field in the electronic and electrical industry. Polycarbonate resin is mainly used in the production of various food processing machinery, electric tool casings, bodies, brackets, refrigerator freezer drawers and vacuum cleaner parts. In addition, polycarbonate also has good electrical insulation over a wide temperature range and has good electrical properties. However, the polycarbonate material itself is not good in friction resistance. In some polycarbonate materials that are easy to wear, special surface treatment is required, which brings inconvenience to use, so further improvement is needed to strengthen its popularization a...
