Abstract

The invention discloses an epoxy resin based anti-static coating and belongs to the technical field of high polymer materials. The epoxy resin based anti-static coating is prepared by the following steps: putting epoxy resin and a diluent in a mixer; stirring and mixing for 40-60min at a rotation speed of 400-600r/min; adding low-melting-point alloy, silver nanowire, a curing agent, drying oil, acoupling agent, coated sodium peroxide, calcium bicarbonate, alkaline phenolic resin and dry soybean oil into the mixer; stirring and mixing for 40-60min at a rotation speed of 400-600r/min to obtainthe epoxy resin based anti-static coating. The epoxy resin based anti-static coating provided by the invention has excellent anti-static property and mechanical property.

Description

technical field [0001] The invention discloses an epoxy resin-based antistatic coating, which belongs to the technical field of polymer materials. Background technique [0002] With the development of high technology and the wide application of polymer materials, the problem of static electricity has attracted more and more attention from all aspects. Since most polymer materials are excellent electrical insulating materials, their surface resistivity ρs and volume resistivity ρv are very large (ρs is about 10 14 ~10 17 Ω, ρv is about 10 15 ~10 18 Ω·m), it is easy to accumulate a large amount of static charge, which hinders the production process and product quality, and causes fire, explosion and other accidents. Antistatic coatings can eliminate the hazards of static electricity, and are widely used because of their simple production equipment, convenient construction, and low cost. [0003] Antistatic coating is a functional coating developed rapidly in the past 10 y...
