Problems solved by technology

On the one hand, the reason is that the road is snowy in winter, and on the other hand, the glass inside the car is covered by water, which affects the driver's sight and hinders driving safety.
At present, it is generally used to coat the glass with an anti-fogging agent composed of a surfactant to solve this problem, but its operation is cumbersome.

Embodiment Construction

[0020] An anti-fog self-cleaning automobile glass, which comprises: a glass body, an anti-fog layer, a protective film and a photocatalyst coating; the glass body is coated with an anti-fog layer, the anti-fog layer is coated with a protective film, and the protective film is coated with a Catalyst coating;

[0021] The anti-fog layer is formed by spraying an anti-fog agent, and the raw material of the anti-fog agent is an anti-fog automobile glass.

[0022] The anti-fog layer is formed by spraying an anti-fog agent, and the raw materials of the anti-fog agent are: citric acid, Tween-80, silicone oil, oleic acid, polyethylene glycol ester, diglycerin, carbomer and Ionized water; the weight percent of each substance is:

[0023] Citric acid 1~2%

[0024] Tween-80 2~5%

[0025] Silicone oil 2~3%

[0026] Oleic acid 2~5%

[0027] Polyethylene glycol ester 1~2%

[0028] Diglycerol 2~3%

[0029] Carbomer 1~3%

[0030] The balance is deionized water.

[0031] The protective...

Abstract

The invention relates to automotive glass, in particular to anti-fog and self-cleaning automotive glass. An anti-fog coating is arranged on the glass surface, has a good anti-fog function, adopts oleic acid god in wetting ability and strong in detergency and silicone oil as the main components and is doped with and matched with Carbomer and polyglycerol to form the anti-fog content, wherein Carbomer can level easily, and antifogging agent viscosity can be controlled through reacting of Carbomer and the macrogol ester, and accordingly after being used, the anti-fog and self-cleaning automotive glass is attached onto the glass surface and can keep the long-acting anti-fog function. A protective film is arranged on the surface of the anti-fog layer and can protect the anti-fog coating and prolong service life of the anti-fog glass. A photocatalyst coating is covered and painted on the outermost layer of the glass and can be decomposed in ultraviolet irradiation, and therefore the anti-fog and self-cleaning automotive glass has strong hydrophily and has the self-cleaning effect.

Description

[0001] technical field [0002] The invention relates to an automobile glass, in particular to an automobile glass with anti-fog and self-cleaning functions. Background technique [0003] With the continuous development of the automobile industry, the traffic flow on the road is also increasing. It not only brings great pressure to traffic, but also brings certain harm to people's life safety. Especially in winter, the incidence of traffic accidents will increase significantly. On the one hand, the reason is that the road is snowy in winter, and on the other hand, the glass inside the car is covered by water, which affects the driver's line of sight and hinders driving safety. At present, it is generally adopted to cover the glass with an anti-fogging agent composed of a surfactant to solve this problem, but the operation is cumbersome. Contents of the invention [0004] In view of the problems existing in the prior art, the object of the present invention is an automob...
