Embodiment Construction

[0021] An environmentally friendly anti-fog and self-cleaning automotive glass, which includes: a glass body, an anti-fog layer, a protective film and a photocatalyst coating; the glass body is covered with an anti-fog layer, the anti-fog layer is covered with a protective film, and the protective film is covered with Apply a photocatalyst coating;

[0022] The antifogging layer is formed by spraying an antifogging agent, and the raw materials of the antifogging agent are: ethanol, camellia oil, alum, betaine, water glass, cellulose derivatives, sorbic acid alcohol, glycerin and deionized water; The weight percent of each substance is:

[0023] Ethanol 8~10%

[0024] Camellia oil 2~5%

[0025] Alum 1~3%

[0026] Betaine 3~5%

[0027] Water glass 1~2%

[0028] Cellulose derivatives 2~4%

[0029] Sorbitol 1~3%

[0030] Glycerin 2~4%

[0031] The balance is deionized water.

[0032] The weight percent of described each material is preferably: ethanol 9%, camellia oil 4%,...

Abstract

The invention relates to automobile glass, in particular relates to an environmentally-friendly antifogging and self-cleaning automobile glass and belongs to the field of glass. The glass is provided on the surface with an antifogging coating which has a good antifogging function and is prepared by utilizing ethanol and de-ionized water as solutions, alum and lycine as emulsifying agents, and soluble glass, a cellulose derivative and tea oil as dispersants, wherein alum is soluble in water for producing colloidal aluminum hydroxide and has very high adsorptive capacity, thus well enhancing the dispersibility of the automobile glass and improving the defogging effect. At the same time, any substance harmful to a human body is not added, and the automobile glass is suitable to be used for a long time. Moreover, the antifogging layer is provided on the surface with a protective film which has the function of protecting the antifogging coating, thus prolonging the service life of the antifogging glass; and the outermost layer of the glass is coated with a photocatalyst coating which is decomposed under ultraviolet irradiation and has very good hydrophilicity, thus playing the self-cleaning function.

Description

[0001] technical field [0002] The invention relates to an automobile glass, in particular to an environment-friendly anti-fog and self-cleaning automobile glass, which belongs to the field of glass. Background technique [0003] In the low temperature season, due to the temperature difference between indoor and outdoor, a large amount of fog is generated on the car glass, which seriously reduces the transparency of the glass, thus affecting the driver's sight, forcing the driver to wipe the glass continuously during driving, which is easy to cause traffic accidents. In order to eliminate the fog on the car glass, some people have invented some defoggers, but these defoggers basically contain toxic and flammable chemical components. Its operation is cumbersome and cannot keep the glass continuously having the anti-fog function. Contents of the invention [0004] In view of the problems existing in the prior art, the object of the present invention is to provide a...
