Embodiment 1
[0027] The present invention provides a transparent car cover with thermal insulation and super-hydrophobic functions. The transparent car cover is prepared by spraying component A and component B on the car paint and drying them respectively. The weight ratio is 4:1. When using, first spray the A component evenly on the car paint and dry it at 25°C. Repeat this spraying and drying for 3 times, then spray the B component. ℃ for 10 minutes to get the finished product; wherein,
[0028] Component A is water-based polyurethane-nano antimony tin oxide composite emulsion;
[0029] Component B is a fluorine-containing silane solution.
[0030] The preparation of the above-mentioned component A water-based polyurethane-nano antimony tin oxide composite emulsion goes through the following steps successively:
[0031] Add 100 parts of polycarbonate diol with a relative molecular mass of 3000 into a sealed dispersion kettle with heating, temperature control and dispersion device, add ...
Embodiment 2
[0037] The present invention provides a transparent car cover with thermal insulation and super-hydrophobic functions. The transparent car cover is prepared by spraying component A and component B on the car paint and drying them respectively. The weight ratio is 100:1. When using, first spray the A component evenly on the car paint and dry it at 70°C. Repeat this spraying and drying for 8 times, then spray the B component, after spraying the B component The finished product is obtained by heating at 150°C for 1 minute; wherein,
[0038] Component A is water-based polyurethane-nano antimony tin oxide composite emulsion;
[0039] Component B is a fluorine-containing silane solution.
[0040] The preparation of the above-mentioned component A water-based polyurethane-nano antimony tin oxide composite emulsion goes through the following steps successively:
[0041] Add 100 parts of polycarbonate diol with a relative mass fraction of 3000 into a sealed dispersion kettle with hea...
Embodiment 3
[0046] The present invention provides a transparent car cover with thermal insulation and super-hydrophobic functions. The transparent car cover is prepared by spraying component A and component B on the car paint and drying them respectively. The weight ratio is 20:1. When using, first spray the A component evenly on the car paint and dry it at 60°C. Repeat this spraying and drying for 4 times, then spray the B component, after spraying the B component The finished product is obtained by heating at 100°C for 3 minutes; wherein,
[0047] Component A is water-based polyurethane-nano antimony tin oxide composite emulsion;
[0048] Component B is a fluorine-containing silane solution.
[0049] The preparation of the above-mentioned component A water-based polyurethane-nano antimony tin oxide composite emulsion goes through the following steps successively:
