Embodiment 1
[0024] (1) Step 1, take 100g of α, ω-dihydroxy polydimethylsiloxane in a beaker, add 10g of filler silica, stir well and add 2g of whitening agent TiO 2 , stir evenly;
[0025] (2) Step 2, add 0.25 g of dodecafluoroheptylpropyltrimethoxysilane and 1 g of methyltrimethoxysilane to the uniformly stirred system in step 1, and add the silane coupling agent γ-glycidyl ether after stirring well Oxypropyltrimethoxysilane 1g, stir well;
[0026] (3) In step 3, add 0.2 g of catalyst dibutyltin dilaurate to the uniformly stirred system in step 2, and then add 30 g of solvent xylene, and stir evenly to obtain a one-component fluorosilicone rubber anti-icing coating material.
Embodiment 2
[0028] (1) Step 1, take 100g of α, ω-dihydroxy polydimethylsiloxane in a beaker, add 40g of filler silica, stir well and add 5g of whitening agent TiO 2 , stir evenly;
[0029] (2) Step 2, add 2 g of tridecafluorooctyltrimethoxysilane and 1 g of methyltriethoxysilane to the uniformly stirred system in step 1, and add the silane coupling agent γ-aminopropyltrimethoxy after stirring well base silane 0.5g, stir evenly;
[0030] (3) In step 3, add 0.1 g of catalyst stannous octoate to the uniformly stirred system in step 2, and then add 10 g of solvent toluene, and stir evenly to obtain a one-component fluorosilicone rubber anti-icing coating material.
Embodiment 3
[0032] (1) Step 1, take 100g of α, ω-dihydroxy polydimethylsiloxane in a beaker, add 5g of filler silica, stir well and add 1g of whitening agent TiO 2 , stir evenly;
[0033] (2) Step 2, add 4-methyl-(perfluorohexylethyl)propyltrimethoxysilane 4g and methyltriacetoxysilane 1g to the uniformly stirred system in step 1, stir well and add silane Coupling agent γ-aminopropyltriethoxysilane 2g, stir well;
[0034] (3) In step 3, add 0.5 g of catalyst dibutyltin dilaurate to the uniformly stirred system in step 2, and then add 40 g of solvent ethyl acetate, and stir evenly to obtain a one-component fluorosilicone rubber anti-icing coating material.
