Glass anti-fog and anti-frost agent and preparation method thereof

Abstract

The invention provides an anti-fog and anti-frost agent for glass and a preparation method thereof. The glass anti-fog and anti-frost agent comprises the following chemical components in percentage bymass: 1-10% of a composite surfactant, 1-10% of polyethylene glycol, 1-10% of glycerol, 0.1-1% of polyvinyl alcohol, 0.1-1% of an emulsifier and the balance of a mixed solution of ethanol and water.The glass anti-fog and anti-frost agent is colorless, transparent and not prone to turbidity, has an antifogging function and an antifrost function, is lasting in antifogging and antifrost effect, cankeep the antifogging and antifrost effect for 60 days or longer, is small in corrosivity, non-toxic, harmless, free of harm to human health, easy to clean and good in practicability.

Description

technical field [0001] The invention relates to the technical field of glass anti-fog agents, in particular to a glass anti-fog and anti-frost agent. At the same time, the invention also relates to a preparation method of the glass anti-fog and anti-frost agent. Background technique [0002] People with car driving experience know that when the weather is relatively cold, the water vapor in the car will condense on the inside of the front and rear windshields and side windows to form small water droplets, that is, form fog, which hinders the driver's line of sight and easily causes traffic accidents. Accidents, this fogging phenomenon is especially obvious in rainy days and winter. In order to prevent fogging, people have developed an anti-fogging agent for automobile glass, which can be sprayed on the inside of the automobile glass and spread evenly to prevent fogging. [0003] Although the existing anti-fogging agents for automobile glass have been marketed, the product ...

AI Technical Summary

Problems solved by technology

[0006] 1. The anti-fog and anti-frost agent for automobile glass prepared according to the existing patent, the effect duration is short, the anti-fog effect is 3-7 days, and the anti-frost effect is 1-2 days. In winter, if the user wants to obtain a continuous anti-fog and anti-frost effect , you need to spray the anti-fog and anti-frost agent once a day (up to every other day), which is time-consuming and labor-intensive

[0007] 2. Existing anti-fog and anti-frost agents are highly corrosive and toxic. One is to corrode the interior of the car, and the other is to make drivers and passengers exposed to this spraying environment for a long time, which will cause great harm to the body.

[0008] 3. Anti-fog and anti-frost agents have both anti-fog and anti-frost functions. There are many types of corresponding effective chemical components, the appearance of the product will be turbid, and it will be stratified or precipitated during storage, which will affect the quality of the product. use

[0009] 4. The anti-fogging agent products with nanotechnology sold online, although the anti-fogging effect is good, the product is nominally 1 month, but the actual measurement effect can last for about 20 days, and the existing glass anti-fogging agent has an adhesion effect on the glass Too strong, it is not easy to clean after its function fails, and it is easy to form long-term residue on the glass
