A special composite coating material for power equipment

Abstract

The invention discloses a composite coating material dedicated for power equipment, and belongs to the technical field of power coatings. The composite coating material is prepared from the followingingredients: 15-20 parts by weight of polyaniline, 2-5 parts by weight of polymethyl methacrylate, 6-10 parts by weight of trichloromethane, 40-52 parts by weight of N,N-dimethylformamide, 15.2-18.5 parts by weight of sodium silicate, 2.5-3.6 parts by weight of lauryl sodium sulfate, 12.3-13.8 parts by weight of antirust agent, 5.8-6.6 parts by weight of waterproof agent, 3.5-4.3 parts by weight of heat-resistance agent, 8.7-9.5 parts by weight of anti-corrosion agent, 22-28 parts by weight of acetone and 46-55 parts by weight of water. The composite coating material dedicated for the power equipment has the advantages of good mechanical performance and insulation performance, water and chemical corrosion resistance, high adhesive force, stable performance under a high and low temperatureenvironment, rust resistance and excellent overall performance and can keep stable in an acid and alkali environment for a long time.

Description

technical field [0001] The invention relates to the technical field of electrical coating materials, in particular to a composite coating material dedicated to electrical equipment. Background technique [0002] With the development of the national power industry, the coverage area and density of the power supply grid are increasing, and the safety of the line has become inseparable from our daily life and work. As an important part of the transmission line, power equipment mainly includes two categories: power generation equipment and power supply equipment. Power generation equipment is mainly power plant boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc., and power supply equipment is mainly transmission lines, transformers, contactors, etc. of various voltage levels. If one of the devices is compromised, the entire line is affected. [0003] At present, in the transmission line, most of the power equipment is exposed outside, without ...

Problems solved by technology

However, the preparation method of this invention is to simply mix the raw materials, and a large amount of impurities will be doped during the preparation process, which will affect the purity of the material. After testing, the acid and alkali corrosion resistance of this invention is poor, and the temperature application range is small.
