Embodiment 1
[0036] A. Prepare materials according to the formula of transparent hydrophobic film sol:
[0037] The transparent hydrophobic film sol component and volume ratio are:
[0038] Orthosilicon tetraethyl ester: absolute ethanol: n-butanol: isopropanol: water: active substance = 8-10: 35-50: 1.5-4: 5-8: 0.01-0.35: 0.03-2;
[0039] The active substance in this example is organosilane, specifically, organosilane is methyltriethoxysilane, 3-(heptafluoroisopropoxy)propyl trichlorosilane and γ-glycidyl etheroxypropyl trimethyl Silane is prepared according to the following formula, and the components of the transparent hydrophobic film sol are measured in liters, which are respectively:
[0040] Orthosilicon tetraethyl ester: absolute ethanol: n-butanol: isopropanol: water: methyltriethoxysilane: 3-(heptafluoroisopropoxy)propyltrichlorosilane: γ-glycidyl ether oxygen Propyltrimethylsilane = 8:45:3.5:6.5:0.15:0.5:0.6:0.22.
[0041] B. After fully mixing the active substance organosila...
Embodiment 2
[0047] Different from Example 1, the described sol component and volume ratio are:
[0048] Orthosilicon tetraethyl ester: absolute ethanol: n-butanol: isopropanol: water: organosilane = 8.5~10: 35~45: 2~4: 6~8: 0.01~0.3: 0.03~1.5.
Embodiment 3
[0050] Different from embodiment 1,2, described sol component and volume ratio are:
[0051] Tetraethyl tetraethyl ester: absolute ethanol: n-butanol: isopropanol: water: methyltriethoxysilane = 8: 45: 3.5: 6.5: 0.15: 1.5.
