Embodiment 1

[0020] A high-temperature-resistant and anti-corrosion coating for power distribution systems, which is prepared from the following raw materials in parts by weight:

[0021] 8 parts of triethanolamine oleic acid soap, 7 parts of dimethyl phthalate, 6 parts of n-butanol, 5 parts of emulsified silicone oil, 3 parts of lithium bentonite, 2 parts of sodium citrate, 2 parts of isobornyl acetate, camphor 2 parts oil, 1 part sodium silicate, 1 part aluminum nitride, 1 part tobacco extract and 1 part fennel extract.

[0022] The particle diameters of the lithium-based bentonite, sodium citrate and aluminum nitride are all controlled at 500 mesh; the modulus n of the sodium water glass is 2.8.

[0023] It is prepared according to the following process:

[0024] 1) Preparation of tobacco extract: dry the tobacco so that the water content is lower than 10% (weight fraction), then add twice the weight of 70% (volume fraction) ethanol to reflux for extraction for 1 hour, collect the extr...

Embodiment 2

[0030] A high-temperature-resistant and anti-corrosion coating for power distribution systems, which is prepared from the following raw materials in parts by weight:

[0031] 10 parts of triethanolamine oleic acid soap, 8 parts of dimethyl phthalate, 7 parts of n-butanol, 6 parts of emulsified silicone oil, 4 parts of lithium bentonite, 3 parts of sodium citrate, 3 parts of isobornyl acetate, camphor 3 parts oil, 2 parts sodium silicate, 2 parts aluminum nitride, 2 parts tobacco extract and 2 parts fennel extract.

[0032] The particle diameters of the lithium-based bentonite, sodium citrate and aluminum nitride are all controlled at 500 mesh; the modulus n of the sodium water glass is 2.8.

[0033] It is prepared according to the following process:

[0034] 1) Preparation of tobacco extract: dry the tobacco so that the water content is lower than 10% (weight fraction), then add twice the weight of 70% (volume fraction) ethanol to reflux for extraction for 1 hour, collect the...

Embodiment 3

[0040] 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:

[0041] Table 1

[0042]

[0043] Conclusion: The coatings prepared in Example 1 and Example 2 of the present invention have better corrosion resistance and high temperature resistance.

Abstract

The invention belongs to the technical field of power distribution system protection, and discloses a high-temperature-resistant anti-corrosion coating for a power distribution system. The high-temperature-resistant anti-corrosion coating for the power distribution system is prepared from, by weight, 8-10 parts of triethanolamine oleic soap, 7-8 parts of dimethyl phthalate, 6-7 parts of n-butanol, 5-6 parts of emulsified silicone oil, 3-4 parts of lithium-base bentonite, 2-3 parts of sodium citrate, 2-3 parts of isobornyl acetate, 2-3 parts of camphor oil, 1-2 parts of sodium water glass, 1-2 parts of aluminium nitride, 1-2 parts of tobacco extract and 1-2 parts of fennel extract. The high-temperature-resistant anti-corrosion coating for the power distribution system has the multiple functions of resisting high temperature and corrosion and repelling birds.

Description

technical field [0001] The invention belongs to the technical field of power distribution system protection, and relates to a high-temperature-resistant and anti-corrosion paint used in a power distribution system and a preparation process thereof. Background technique [0002] In the power distribution system, the cable conductor is an important part, which is made of one or more mutually insulated conductors and an outer insulation protection layer, and is used to transmit power or information from one place to another. In the outdoor environment, especially in hot and humid climates or areas with severe acid-base-salt effects, aging, corrosion, and damage of power transmission and transformation cables are prone to occur, which can easily cause transmission line failures and bring great harm to people's normal production and life. It will have a greater impact and cause greater losses to the power sector. In order to overcome the above-mentioned defects, cable anti-cor...
