[0020] Vinyl resin 50, polyvinylpyrrolidone 30, decabromodiphenylethane 25, emulsified silicone oil 22, phthalate 15, polysiloxane 15, 2-bromo-2-nitro-1.3-propanediol 8, Sodium carboxymethyl cellulose 6, aluminum tripolyphosphate 5, water glass 4, tungsten carbide 3, titanium carbide 3, lithium bentonite 2, sodium citrate 1, water 30.

[0021] The preparation method of the above-mentioned environmental protection transmission line anticorrosion coating comprises the following steps:

[0022] 1) taking the above-mentioned raw materials according to parts by weight for subsequent use;

[0023] 2) Send tungsten carbide, titanium carbide and lithium-based bentonite to a ball mill, grind to a powder with a particle size of 500 mesh or more, then mix the powder with sodium water glass, and stir to obtain a mixture 1;

[0024] 3) ...

Embodiment 2

[0028] An environmentally friendly anticorrosion coating for transmission lines, which is prepared from the following raw materials in parts by weight:

[0029] Vinyl resin 60, polyvinylpyrrolidone 40, decabromodiphenylethane 30, emulsified silicone oil 24, phthalate 20, polysiloxane 20, 2-bromo-2-nitro-1.3-propanediol 12, Sodium carboxymethyl cellulose 9, aluminum tripolyphosphate 8, water glass 6, tungsten carbide 5, titanium carbide 5, lithium bentonite 3, sodium citrate 2, water 40.

[0030] The preparation method of the above-mentioned environmental protection transmission line anticorrosion coating comprises the following steps:

[0031] 1) taking the above-mentioned raw materials according to parts by weight for subsequent use;

[0032] 2) Send tungsten carbide, titanium carbide and lithium-based bentonite to a ball mill, grind to a powder with a particle size of 500 mesh or more, then mix the powder with sodium water glass, and stir to obtain a mixture 1;

[0033] 3)...

Embodiment 3

[0036] The performance test of the anticorrosion paint prepared by the present invention:

[0037] Soak the ordinary BV cable in the paint for 10 minutes, then take it out and let it stand for 12 hours, and test the indicators of each item. The specific test results are shown in Table 1:

[0038] Table 1

[0039]

[0040]

[0041] At the same time, we also tested the water absorption rate and non-breakdown voltage of the cable; soaked for 48 hours, the absorption rate is less than 0.01%; the non-breakdown voltage is about 4KV / 100um.

[0042] Conclusion: the anti-corrosion coating prepared by the invention can better resist acid, alkali, salt and steam corrosion, and has better water absorption and insulation performance, which greatly improves the service life of the transmission line and reduces safety hazards at the same time.

Abstract

The invention belongs to the technical field of power transmission line protection and discloses an environmental-friendly anticorrosive paint for a power transmission line. The paint is prepared from the raw materials in parts by weight: 60 parts of vinyl chloride-vinyl acetate copolymer, 40 parts of polyvinyl pyrrolidone, 30 parts of decabromodiphenyl ethane, 24 parts of emulsified silicone oil, 20 parts of phthalate, 20 parts of polysiloxane, 12 parts of 2-bromo-2-nitro-1,3-propanediol, 9 parts of sodium carboxymethyl cellulose, 8 parts of aluminum tripolyphosphate, 6 parts of water glass, 5 parts of tungsten carbide, 5 parts of titanium carbide, 3 parts of lithium-based bentonite, 2 parts of sodium citrate and 40 parts of water. The anticorrosive paint disclosed by the invention has the advantages that the power transmission line is resistant to corrosion of acid, alkali, salt and steam, the service life of the power transmission line is prolonged greatly, and meanwhile, potential safety hazards are reduced.

Description

technical field [0001] The invention belongs to the technical field of electric power transmission line protection, and relates to an environment-friendly anticorrosion coating for power transmission lines. Background technique [0002] Power transmission is achieved by using a transformer to boost the power generated by the generator, and then connecting it to the transmission line through circuit breakers and other control equipment. According to the structural form, transmission lines are divided into overhead transmission lines and cable lines. The overhead transmission line is composed of line towers, wires, insulators, line fittings, guy wires, tower foundations, grounding devices, etc., and is erected above the ground. According to the nature of the transmission current, power transmission is divided into AC transmission and DC transmission. In the 1880s, DC transmission was first successfully realized. However, because the voltage of DC transmission was difficult ...
