Glazed automobile protective film with high electric insulativity

Abstract

The invention discloses a glazed automobile protective film with high electrical insulating property and belongs to the technical field of film manufacturing and application. The protective film sequentially comprises a polyester film layer, an insulating protective film layer and an ultraviolet-proof layer, and the polyester film layer is prepared from the following components: polyamide resin, adispersing agent, a plasticizer, an antioxidant and a film-forming agent; the insulating protective film layer is prepared from the following components: polyethylene, silicon nitride and polyester fibers; the ultraviolet-proof layer is prepared from the following components: epoxy resin, oily nano titanium dioxide and one or more of zinc oxide, titanium oxide and cerium oxide; according to the invention, three layers of protective films used for protection successively include the polyester film layer, the insulating protective film layer and the ultraviolet-proof layer in sequence. The protective film disclosed by the invention has the functions of oxidation resistance and ultraviolet resistance by utilizing the combination of multi-component substances.

Description

technical field [0001] The invention belongs to the technical field of film manufacture and application, in particular to a glazing automobile protective film with strong electrical insulation. Background technique [0002] With the rapid development of the automobile industry, people's vision is always limited to the research of automobile structure, and there is less research on automobile protective film. [0003] Because the car protective film is exposed to the external environment for a long time, the film on the surface of the car will be damaged to varying degrees in the long-term external environment, especially the decolorization or oxidation of the surface layer is the most common. Not all of them are oxidized, but local oxidation and corrosion in pieces. What's more serious is that the surface layer becomes off-white powder, which directly affects the appearance of the car and the cost of maintaining the car. Although the cable insulation layer with anti-oxidati...

AI Technical Summary

Problems solved by technology

Although the cable insulation layer with anti-oxidation function has also appeared on the market, the anti-oxidation effect is still not ideal, which brings unfavorable factors to the long-term maintenance and use of automobiles.

[0004] There are still problems with ultraviolet rays in the existing technology of automobile film manufacturing. Usually, the damage of ultraviolet rays to the skin can induce canceration, aging and fading of the surface of the car, etc. How to prevent the surface of the car from being harmed by ultraviolet rays has always attracted attention.

Moreover, the environmental pollution in the atmosphere is becoming more and more serious, and the ozone layer is destroyed, so that the protective film on the surface of the car to prevent aging cannot be naturally blocked from ultraviolet rays.
