Abstract

The invention discloses a coating for electric power fittings and a preparation method thereof. The coating for the electric power fittings is composed of, by mass, 60-80 parts of a silica solution, 15-30 parts of epoxy resin, 15-25 parts of polyester resin, 10-16 parts of SHP-50 polysiloxane powder, 15-20 parts of polyimide resin, 7-12 parts of acetylene black, 6-15 parts of nanometer titania, 8-10 parts of water glass, 4-8 parts of petroleum asphalt, 8-15 parts of guar gum WP-05, 6-10 parts of SER-AD FA 179, 3-5 parts of diethylenetriamine, 2-4 parts of antioxygen 1076, 5-8 parts of phosphate aluminum-chromium and 1-3 parts of a sodium hydroxide solution. The coating is prepared through the steps of mixed smelting, crushing, mixing, stirring, aging and the like. The coating has the advantages that the coating has excellent corrosion resistance and corona resistance, gathering of electric charges can be reduced, the probability of partial discharge breakdown is lowered, the corona-resistant protective effect is achieved, and the problems of aging, corrosion and the like in the use process of the electric power fittings are effectively prevented.

Description

technical field [0001] The invention relates to the field of protective coatings for metal fittings, in particular to a coating for electric metal fittings and a preparation method thereof. Background technique [0002] Power fittings are metal accessories that connect and combine various devices in the power system to transmit mechanical loads, electrical loads and some kind of protection, and play an important role in power transmission and transformation projects. Product quality is not only related to the safe operation of the power grid, but also related to personal and property safety. Therefore, it is a very important task to ensure the product performance and service life of power fittings. Power fittings are mainly metal cast iron, which are prone to corrosion, aging and other problems during long-term use. At present, the commonly used method for protecting metal materials is to paint the protective layer on the surface. [0003] In the Chinese published patent a...
