Problems solved by technology

[0003] is mainly used in transparent plastic film, sheet or board. In a humid environment, when the humidity reaches below the dew point, a layer of fine water droplets will condense on the surface. The surface is blurred and fogged, which hinders the transmission of light waves. For example, 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

[0015] An antifogging agent for automobile glass, which contains the following ingredients in weight percentage: 15-18% polyglyceryl stearate, 16-20% sorbitan monostearate (S-60), 16-20% sorbitan monostearate Palmitate (S-40) 14-18%, fatty alcohol and ethylene oxide condensate 14-18%, simethicone 14-20%, hawthorn seed oil 2-6%, alum 2-8%. Mix and stir at a temperature of 40-50 degrees.

[0016] Instructions:

[0017] 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 an...

Abstract

The invention relates to an antifogging agent and especially relates to an automobile glass antifogging agent and a preparation method thereof. The automobile glass antifogging agent comprises, by weight, 15-18% of polyglycerol monostearate, 16-20% of sorbitan monstearate (S-60), 14-18% of sorbitan monopalmitate (S-40), 14-18% of fatty alcohol-oxirane condensate, 14-20% of dimethicone, 2-6% of haw seed oil and 2-8% of alum. The preparation method adopts easily available raw materials, has simple production processes and is convenient for adjustment. The automobile glass antifogging agent has 100% of antifogging effects on toughened glass, optical lens and plastic lens and can prevent mirror surface aging and oxidation. The automobile glass antifogging agent can substantially reduce a liquid ice point thereby producing antifreezing effects and can fast dissolve ice and frost.

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 genera...
