Problems solved by technology

[0003] 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

[0013] An antifogging agent for automobile glass, which contains the following ingredients in weight percentage: 15-18% of polyglyceryl stearate, 16% of sorbitan monostearate (S-60), 16% of sorbitan monopalmitic acid Ester (S-40) 14%, fatty alcohol and ethylene oxide condensate 14%, simethicone 14%, hawthorn seed oil 2%, alum 2%. Mix and stir at a temperature of 40-50 degrees.

[0014] Instructions:

[0015] 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...

Embodiment 2

[0017] An antifogging agent for automobile glass, which contains the following components in weight percentage: 15-18% of polyglyceryl stearate, 20% of sorbitan monostearate (S-60), 20% of sorbitan monopalmitic acid Ester (S-40) 18%, fatty alcohol and ethylene oxide condensate 18%, simethicone 20%, hawthorn seed oil 6%, alum 8%. Mix and stir at a temperature of 40-50 degrees.

[0018] Instructions:

[0019] 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.

Embodiment 3

[0021] A kind of antifogging agent for automobile glass, containing the composition of following percentage by weight: polyglyceryl stearate 16%, sorbitan monostearate (S-60) 18%, sorbitan monopalmitate ( S-40) 15%, fatty alcohol and ethylene oxide condensate 16%, simethicone oil 18%, hawthorn seed oil 4%, alum 5%. Mix and stir at a temperature of 40-50 degrees.

[0022] Instructions:

[0023] 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.

Abstract

The invention relates to an antifoggant and particularly relates to an antifoggant for automobile glass and a preparation method thereof. The antifoggant comprises the following components in percentage by weight: 15%-18% of polyglycerol stearate, 16%-20% of sorbitan monostearate (S-60), 14%-18% of sorbitan palmitate (S-40), 14%-18% of fatty alcohol and ethylene oxide condensation compound, 14%-20% of simethicone, 2%-6% of hawthorn seed oil and 2%-8% of alums. The antifoggant provided by the invention is easily available in raw materials of components, simple in production process and convenient to modulate. The antifoggant provided by the invention not only has a 100% antifogging effect to tempered glass, optical glasses and plastic glasses, but also further can be used for preventing the mirror side from being aged and oxidized. The ice point of a liquid can be remarkably reduced so as to have the anti-freezing effect, so that rime frost can be quickly dissolved.

Description

technical field [0001] The invention relates to an antifogging agent, in particular to an antifogging agent for automobile glass and a preparation method thereof. Background technique [0002] The anti-fog agent uses dispersed anti-drip materials and nano-organic active agents. The surface of the glass treated with the anti-fog agent has a layer of super-hydrophilic nano-film, which makes the fog vapor contact with it to form a mixture with a low freezing point to prevent fogging. The maintenance time can be up to 15 days. And non-toxic, no smell, no corrosion. [0003] 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 the product is packaged in film, the contents will also be invisible due to fogging, and the generated f...
