Embodiment 1
[0022] In this embodiment, the anti-icing high-voltage wire includes a steel core inner layer composed of a steel core, and an aluminum alloy wire outer layer composed of an aluminum alloy wire covering the inner layer. The surface of the outer layer of the aluminum alloy wire is dipped, dip-coated or spin-coated with a treatment liquid, and cured at 60-80° C. for 45-50 minutes after coating to form. The thickness of the anti-icing coating film is 5-50 μm. The treatment liquid consists of 5.0-5.5 wt% ethylene glycol dimethacrylate, 3.5-5.0 wt% glycidyl methacrylate, 1.2-1.5 wt% alkylphenol ether sulfosuccinate, 2.0 ~2.2wt% acrylamide, 0.8~1.0wt% modified nano-SiO 2 It is composed of monomer, 1.0-1.2wt% of aluminum hydroxide and the balance of solvent. The solvent is at least two selected from xylene, isopropanol, n-butanol, methyl acetate, ethyl acetate, butyl acetate, ethylene glycol ether, and N-methylpyrrolidone.
Embodiment 1A
[0024] In this example, first, the nano-SiO 2 Reaction with 3-aminopropyltriethoxysilane in anhydrous toluene solution at 50°C to obtain amino-modified nano-SiO 2 , where 3-aminopropyltriethoxysilane and nano-SiO 2 The mass ratio is 1:5; then, in N,N-dimethylformamide solution, add maleic anhydride, stir and dissolve to obtain a mixed solution completely; in the amino-modified nano-SiO 2 Add N, N-dimethylformamide to the mixture and stir to obtain a dispersion; add the dispersion dropwise to the mixed solution, then stir at 70°C to complete the reaction, and the obtained reaction product can be obtained after washing, filtering and drying The modified nano-SiO 2 monomer, wherein the maleic anhydride and nano-SiO 2 The mass ratio is 1:5.
Embodiment 1B
[0026] In this embodiment, the surface of the outer layer of the aluminum alloy wire is impregnated with a treatment solution consisting of 5.0 wt% ethylene glycol dimethacrylate, 5.0 wt% glycidyl methacrylate, 1.2 wt% alkane phenol ether sulfosuccinate, 2.0wt% acrylamide, 0.8wt% modified nano-SiO 2 Monomer (Example 1A), 1.0 wt% aluminum hydroxide, 15 wt% ethyl acetate, and the balance N-methylpyrrolidone. After coating, the anti-icing coating film can be obtained by curing at 100° C. for 45 minutes, and the thickness of the anti-icing coating film is controlled to be 10 μm.
