Process for producing vehicle glass antifogging agent

Abstract

The invention relates to a method for preparing an automobile glass antifoggant, wherein deionized water is added into a reaction kettle, and 0.1-0.6 percent of high molecular filmogen is added, heated to 40 DEG C, and agitated until dissolved, then 0.6-4.0 percent of fatty alcohol polyethenoxy ether or nonyl phenol polyethenoxy ether nonionics, 0.1-0.6 percent of coconut fatty alkyl trimethyl chloride or lauryl amphoteric propyl juanacidate cationic surfactant, and 0.2-1.0 percent mono ethanol amine or trolamine acidity modifier are added orderly; finally, 5.0-30 percent of isopropyl alcohol, ethanol, propanediol, and propanetriol are added, evenly agitated until the temperature lowers to the room temperature, and then the glass antifoggant is obtained. The invention has the advantages that the use is simple; the glass atomizing effect is good; dust can not be absorbed on the surface of the glass after the drying process, and no trace is left on the surface; the product is colorless and flavorless, safe and reliable.

Description

Technical field: [0001] The invention relates to a preparation method of an antifogging agent for automobile glass, which is composed of a polymer film-forming agent and an active agent, and belongs to the field of daily chemical industry. technical background: [0002] In addition to the electric heating anti-fog device on the front windshield of high-end cars, the side windows, rear window glass and windshields of general automobiles such as passenger cars, agricultural vehicles, and large trucks have no anti-fog devices. In winter, when there is a temperature difference between the inside and outside of the vehicle, or when the humidity is high in rainy days, the water vapor in the air will condense on the glass surface when it is cold, making the glass surface atomized. When the car windshield is atomized, it will seriously affect the driver's sight. At present, there are a small amount of glass anti-fogging agent products on the market, most of which are bottled liquid ...

[0002] In addition to the electric heating anti-fog device on the front windshield of high-end cars, the side windows, rear window glass and windshields of general automobiles such as passenger cars, agricultural vehicles, and large trucks have no anti-fog devices. In winter, when there is a temperature difference between the inside and outside of the vehicle, or when the humidity is high in rainy days, the water vapor in the air will condense on the glass surface when it is cold, making the glass surface atomized. When the car windshield is atomized, it will seriously affect the driver's sight

At present, there are a small amount of glass anti-fogging agent products on the market, most of which are bottled liquid products. When using it, you need to spray the anti-fogging agent on the glass or on a paper towel, and then apply it evenly with a clean paper or cloth towel until it is polished. , it is inconvenient to carry and use, it is easy to stain car seats, car panels and other parts when spraying, and the anti-fog time is short and the effect is not good, it is easy to leave traces and absorb dust after drying
