Abstract
The invention relates to the technical field of chemical washing agent synthesis, and particularly relates to a glass antifogging agent specially used for automobiles and a preparation method of the antifogging agent. The method includes, at room temperature and under atmospheric pressure, mixing 1-5 mg of silicon powder, 1-5 mL of lauryl dimethyl amine oxide, 1-5 mL of glycerol, 1-5 mg of sodium cumenesulfonate and 1-5 mL of glacial acetic acid and shaking to make the mixture uniform to obtain an A solution; mixing 1-5 mL of an alkylbenzenesulfonic acid, 2-5 mL of isopropanol, 55-90 mL of deionized water, 0.1-0.5 mL of glacial acetic acid and 1-5 mL of polyvinylpyrrolidone to obtain a B solution; adding slowly the B solution into the A solution under stirring to perform a hydrolysis reaction to obtain the agent, and coating the agent on a glass surface. Beneficial effects of the antifogging agent are that: the antifogging agent has an excellent antifogging effect, a brightening effect, high glass transparency, an antistatic function, a dust reducing function and an anti-reflecting function; the antifogging agent is an aqueous material and is environmental friendly, clean, nonflammable, nonexplosive, nontoxic and non-corrosive; the antifogging agent is safe to use and convenient to carry; and the antifogging agent is good in transparency, good in degree of finish, and stable in performance.
Description
technical field [0001] The invention relates to the technical field of chemical cleaning synthesis, in particular to an antifogging agent for glass for automobiles and a preparation method thereof. Background technique [0002] Cars According to foreign standards, 20 cars per 100 households has reached the minimum limit of the car society. my country has more than 90 million automobiles. Automobiles will have a greater impact on population, ecological environment, changes in cities and communities, culture and traditional customs. From the perspective of society, the study of automobiles and some of the problems it brings is mainly to solve the problem of traffic accidents. So, how do we solve traffic accidents? The main problem is the driving safety of the car in a specific environment. In winter or in heavy fog, the fog of the car glass is the biggest problem causing accidents. The solution to this problem is to condense water droplets on the surface of the car glass to...
