Long-acting antifogging agent for glass

Abstract

The invention provides a long-acting antifogging agent for glass, which belongs to the technical field of daily chemical products. The long-acting antifogging agent comprises, by weight, 5 to 8 parts of ethanol, 2 to 4 parts of silica sol, 1 to 2 parts of octyltrimethoxysilane, 1 to 2 parts of methyltrimethoxysilane, 1 part of essence, 2 to 4 parts of lauramidopropyl betaine, 3 to 5 parts of sec-octylphenol polyoxyethylene ether, 15 to 18 parts of isopropanol, 3 to 6 parts of methyl n-butyl titanate, 2 to 3 parts of alkyl pyrrolidone, 1 part of trisodium phosphate, 3 to 4 parts of alkanolamide, 1 part of a surfactant and 20 to 40 parts of water. The antifogging agent for glass provided by the invention can effectively prevent formation of droplets on glass and action effects of the antifogging agent lasts for a long time.

Description

technical field

[0001] The invention provides a long-acting antifogging agent for glass, which belongs to the technical field of daily chemical products. Background technique

[0002] In autumn and winter or areas with high humidity, due to the large temperature difference or high humidity, fog will be generated on the surfaces of automobile glass, glasses, glass windows, etc., which will greatly affect the line of sight or light exposure. The fog on the surface of the car glass will force the driver to wipe the glass continuously, which will easily lead to traffic accidents. The water mist or droplets on the surface of glasses and glass windows will bring inconvenience to people's life, work and production. At present, the common glass anti-fogging agents are generally composed of surfactants, alcohol solvents or ether solvents, etc. The anti-fog time is generally 1 to 2 days, the anti-fog time is short, and the anti-fog effect is poor. Contents of the invention

Examples

Embodiment Construction

[0010] Take each component by weight ratio in Table 1.

[0011] The weight proportion of table 1 embodiment 1~embodiment 3

[0012]

[0013] The above water is deionized water. Above-mentioned surfactant is sodium dodecylsulfonate. Anti-fog performance characterization method

[0014] According to the standard view test method, hang the standard view table, and name the mark lines on the view table from the lowest row to 10, 9, 8...2, 1, that is, subtract one from the lowest row. . Wipe the anti-fogging agent on the glass, dry it at room temperature, put it in the refrigerator, take it out after 5 minutes, put it in front of your eyes and stand in a suitable position, observe the lowest row of the standard view table that can be seen through the glass sample , and determine the anti-fog level of the anti-fog agent with the level of this line. The common anti-fogging agent in the market was used as a control.
