Problems solved by technology

[0006] 3. Waterproof film for car mirrors: Water droplets will form on the glass in rainy days, especially on the rear view mirror. After the water droplets form, the driver's vision will be poor and pose a threat to safe driving
[0008] It is mainly used in transparent plastic films, sheets or plates. In a humid environment, when the humidity reaches below the dew point, a layer of fine water droplets will condense on the surface, making the surface blurred and atomized, hindering the transmission of light waves. For example, using When packaging products with film, the contents will also be invisible due to fogging, and the generated mist droplets will easily cause rot and damage to the contents

Embodiment 1

[0017] A kind of antifogging agent for automobile glass, containing the composition of following percentage by weight:

[0018] Sorbitan monostearate (S-60) 16-20%, methyl trifluoropropyl silicone oil 2-5%, sorbitan monopalmitate (S-40) 14-18%, volatile Perfluorinated oil 2-5%, 1,5 pentanediol 2-5%, sodium benzoate 0.5-2.5%, deionized water 45-65%.

[0019] Instructions:

[0020] Wipe the windshield clean first, then spray the defogger on it, let it dry for 1-2 minutes, and then wipe it clean with a dry towel. In this way, a transparent protective film will be formed on the glass, which can effectively prevent water vapor from condensing on the glass to form a fog layer. Generally, spraying once can prevent fog for about a week. It will be better to use it before the fog is formed in the car. Sometimes, after the wiper is started, a proper amount of the present invention is sprayed on the windshield outside the car, the oil film and dirt on the glass will be scraped off, a...

Embodiment 2

[0022] A kind of antifogging agent for automobile glass, containing the composition of following percentage by weight:

[0023] Sorbitan monostearate (S-60) 18%, methyl trifluoropropyl silicone oil 4%, sorbitan monopalmitate (S-40) 16%, volatile perfluorinated oil 4% , 1,5 pentanediol 4%, sodium benzoate 1.5%, deionized water 52.5%.

[0024] Instructions:

[0025] Wipe the windshield clean first, then spray the defogger on it, let it dry for 1-2 minutes, and then wipe it clean with a dry towel. In this way, a transparent protective film will be formed on the glass, which can effectively prevent water vapor from condensing on the glass to form a fog layer. Generally, spraying once can prevent fog for about a week. It will be better to use it before the fog is formed in the car. Sometimes, after the wiper is started, a proper amount of the present invention is sprayed on the windshield outside the car, the oil film and dirt on the glass will be scraped off, and the line of s...

Abstract

The invention relates to an antifogging agent and in particular relates to an automotive glass antifogging agent. The automotive glass antifogging agent comprises the following components in percentage by weight: 16-20 percent of sorbitan monostearate (S-60), 2-5 percent of methyl trifluoropropyl silicone oil, 14-18 percent of sorbitan monopalmitate (S-40), 2-5 percent of volatile perfluorinated oil, 2-5 percent of 1,5-pentanediol, 0.5-2.5 percent of sodium benzoate and 45-65 percent of deionized water. The automotive glass antifogging agent disclosed by the invention has excellent hydrophobicity and antifogging function and has high-temperature resistance and enhanced stain resistance; the antifogging time can be prolonged and the antifogging effect is improved; the automotive glass antifogging agent is wide in application range and low in cost and does not have a side effect on the human body; the antifogging effect has the effects of protecting glass from rain, cleaning the glass and protecting the windscreen wiper after applied to the automobile outside glass and a rearview mirror; and the antifogging agent takes water as a solvent, eliminates inflammable and explosive hazards and is convenient to carry.

Description

technical field [0001] The invention relates to an antifogging agent, in particular to an antifogging agent for automobile glass. Background technique [0002] Anti-fogging agent for automobile glass is mainly used for anti-fogging work inside and outside the car, reducing the condensation phenomenon caused by moisture on the surface of glass and plastic, and reducing the occurrence of traffic accidents. [0003] Application of anti-fogging agent for automobile glass: [0004] 1. Anti-fog for internal use: In rainy, foggy, cold days, when condensation fog occurs on the inner surface of the windshield of the car, use a clean towel or paper towel to wipe the place where the condensation fog is generated evenly, and then it can play an anti-fog effect; [0005] 2. Effectively remove the dirt and grease on the windshield of the car, make the windshield bright as new, improve the clarity, and greatly help driving safety; [0006] 3. Waterproof film for car mirrors: Water drople...
