Plastic anti-static coating

Abstract

The invention relates to a plastic anti-static coating which comprises the following components in parts by mass: 10-50 parts of acrylic resin, 5-20 parts of a nitrocellulose liquid, 10-20 parts of graphite powder, 1-5 parts of carbon black, 5-10 parts of talcum powder, 1-5 parts of tricresyl phosphate, 1-5 parts of dibutyl phthalate and 5-10 parts of a solvent. The coating provided by the invention is coated to a non-metal surface, so that the electrical resistivity in film volume of the coating can be controlled within 10<4>-10<9> ohm, and therefore, generated electrostatic charges can disappear instantly.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to an antistatic coating suitable for plastics. Background technique [0002] It is easy to generate and accumulate static electricity when the surface between non-metals such as plastics is rubbed or impacted by airflow and liquid. When the accumulation of static electricity reaches a certain level, there will be hard static discharge, which will cause various precision instruments and precision electronic components to break down and be scrapped, and even cause flammable and explosive materials to catch fire or explode, resulting in huge vicious accidents. In addition, the static electricity accumulated on the surface of plastic products is difficult to extract due to the serious dust collection, which affects the appearance of the product in the application of ultra-clean environments (such as operating rooms, computer rooms, precision instruments, etc.).
