Abstract

The invention provides an antifogging agent for automobile glass and a preparation method of the antifogging agent, and relates to the field of surfactants. The antifogging agent is prepared from, by weight, 0.5%-1.5% of a surfactant, 2%-5% of an ethylenediamine derivative, 3%-5% of alkanolamide, 1%-5% of caprolactam, 8%-12% of sodium dodecyl benzene sulfonate, 2%-10% of diphenylene glycol ether, 1%-3% of acetone, 1%-2% of glycerin, 1%-5% of glycerol, 1%-3% of ethylene glycol, 0.01%-0.2% of sodium hydroxide, 0.01%-0.2% of hydrochloric acid, 0.06%-0.1% of essence, 50%-60% of water and the balance low molecule alcohol. The antifogging agent for the automobile glass is good in antifogging effect, long in lasting period and non-corrosive to the glass.

Description

technical field [0001] The invention belongs to the field of surfactants, in particular to an antifogging agent for automobile glass and a preparation method thereof. Background technique [0002] In winter or the rainy season, when the temperature difference between the inside and outside of the car is more than 5 degrees, and there is plenty of water vapor and high humidity in the car, the window glass will fog up. Especially when the front window windshield and the rearview mirror are fogged, the fog will seriously affect the driver's line of sight and hinder driving safety. If the air conditioner is turned on for a long time to drive the fog, the effect is not obvious, and the long-term use of the air conditioner to dehumidify will increase a lot of fuel consumption; some drivers use a towel to wipe the front window glass during driving in order to clear the fog, which is a great safety hazard Driving hazard. It is best to use an anti-fog agent for anti-fog work on aut...
