Problems solved by technology

Another disadvantage of membrane materials is that they have a single function and cannot be adjusted for different requirements.
For example, dark car paint is easy to absorb heat, and the temperature inside the car tends to rise when the sun is directly shining. Cooling down and dissipating heat requires a lot of energy consumption, but general protective films cannot provide heat insulation. Cars are also inevitably stained during storage and driving. It takes money and time to wash the car every time, but there is no suitable car cover for such problems on the market

Abstract

The invention discloses a method for making a transparent car cover with heat-insulating and super-hydrophobic functions. The transparent car cover with heat-insulating and super-hydrophobic functions is sprayed and dried on the car paint by component A and component B respectively. And prepared, the weight ratio of A component and B component is 4-100:1; wherein, A component is a water-based polyurethane-nano-tin-antimony composite emulsion, and B component is a fluorine-containing silane solution. When using, first spray component A evenly on the surface of the car paint and dry it, then spray component B and heat at 80-150°C for 1-10 minutes to obtain an invisible car cover with both heat insulation and super-hydrophobic effects.

Description

technical field [0001] The invention relates to the technical field of car paint protection films, in particular to a method for making a transparent car cover with heat insulation and super-hydrophobic functions. Background technique [0002] It is inevitable that vehicles will be scratched and collided during use, which will cause damage to the paint. Long-term exposure to wind and sun will also cause the paint to age and change color. In order to protect the paint and improve the appearance, various invisible car covers have also emerged as the times require. At present, the mainstream invisible car cover in the market is a TPU protective film, such as a kind of automobile protective film disclosed by the patent of CN 206030690U. The process of applying this kind of protective film is cumbersome, time-consuming and labor-intensive, because the bottom layer of the protective film attached to the car paint is generally hot-melt adhesive or pressure-sensitive adhesive, which...
