Embodiment 1

[0022] A coating for electrical equipment, which is prepared from the following raw materials in parts by weight:

[0023] 30 parts of polyvinylpyrrolidone, 25 parts of vinyltrimethoxysilane, 18 parts of emulsified silicone oil, 15 parts of polyoxyethylene lauryl ether, 12 parts of phthalates, 8 parts of silicon carbide, 6 parts of lithium bentonite, nano 2 parts of silica gel and 1 part of nano titanium dioxide.

[0024] The preparation method of above-mentioned coating comprises the steps:

[0025] 1) Weigh each raw material according to parts by weight for later use

[0026] 2) Add polyvinylpyrrolidone, vinyltrimethoxysilane, emulsified silicone oil, polyoxyethylene lauryl ether and phthalate to the reactor in sequence, and stir at 500 rpm for 3 minutes to obtain the main ingredient;

[0027] 3) Send silicon carbide and lithium-based bentonite to a ball mill, and grind them to a powder with a particle size of 500 mesh, which is the auxiliary material;

[0028] 4) Put nan...

Embodiment 2

[0032] A coating for electrical equipment, which is prepared from the following raw materials in parts by weight:

[0033] 40 parts of polyvinylpyrrolidone, 28 parts of vinyltrimethoxysilane, 22 parts of emulsified silicone oil, 20 parts of polyoxyethylene lauryl ether, 14 parts of phthalates, 10 parts of silicon carbide, 8 parts of lithium bentonite, nano 3 parts of silica gel and 2 parts of nano titanium dioxide.

[0034] The preparation method of above-mentioned coating comprises the steps:

[0035] 1) Weigh each raw material according to parts by weight for later use

[0036] 2) Add polyvinylpyrrolidone, vinyltrimethoxysilane, emulsified silicone oil, polyoxyethylene lauryl ether and phthalate to the reactor in sequence, and stir at 500 rpm for 5 minutes to obtain the main ingredient;

[0037] 3) Send silicon carbide and lithium-based bentonite to a ball mill, and grind them to a powder with a particle size of 600 mesh, which is the auxiliary material;

[0038] 4) Put n...

Embodiment 3

[0043] Taking the cable material as an example, paint the coatings prepared in Example 1 and Example 2 on the outer layer of the cable, and measure the performance parameters of the cable surface, see Table 1 for details:

[0044] Table 1

[0045]

[0046] Conclusion: the coatings prepared in Example 1 and Example 2 of the present invention have better properties, can effectively prevent the corrosion of acid-base salts, and have better high temperature resistance and mechanical properties; the coatings of the present invention improve the performance of power materials. The service life reduces potential safety hazards; the preparation process of the coating of the invention is simple and convenient, and the application method is simple.

Abstract

The invention discloses paint for electrical equipment. The paint is prepared from the following raw materials in parts by weight: 30-40 parts of polyvinylpyrrolidone, 25-28 parts of vinyl trimethoxy silane, 18-22 parts of silicone oil emulsion, 15-20 parts of polyoxyethylene lauryl ether, 12-14 parts of phthalate, 8-10 parts of silicon carbide, 6-8 parts of lithium-based bentonite, 2-3 parts of nanosize silica and 1-2 parts of nano titanium dioxide. The invention further discloses a preparation process of the paint. The paint can be used for effectively preventing corrosion of acid-base slats, prolonging the service life of a cable material and reducing occurrence of potential safety hazards.

Description

[0001] technical field [0002] The invention belongs to the field of paint, and in particular relates to a paint used for electric equipment and a preparation process thereof. [0003] Background technique [0004] Power equipment (power system) 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. Power supply equipment is mainly transmission lines of various voltage levels , transformers, contactors, etc. In view of safety considerations, most electrical equipment needs to have corrosion resistance. In order to overcome the above defects, some anti-corrosion coatings have appeared in the prior art. Generally, they are painted by thermal spraying or galvanizing, and some are painted by anti-corrosion coatings. , the existing problems are: high requirements for anti-corrosion substrate treatment, too thick ...
