Abstract

The present invention relates to surfactant, and provides one kind of glass antifogging agent and its preparation process. The glass antifogging agent consists of surfactant 0.2-1.5wt%, polyether modified organic silicon surfactant 1.5-3.0wt%, and alcohol 9-20wt% except water. The glass antifogging agent is re-compounded with several kinds of surfactant, and has long antifogging period and wide application range and may be used also as glass cleaning agent. In addition, it has water as solvent and has no danger of explosion and is easy to carry about.

Description

technical field [0001] The invention relates to a surfactant and a preparation method thereof, more specifically, the invention relates to a glass antifogging agent and a preparation method thereof. Background technique [0002] In the rainy season and winter, where there is a temperature difference or high humidity, people often encounter the problem of fogging on the glass surface in their lives, which brings many inconveniences to life. For example, the fogging of the windshield of a car will affect driving safety and even bring life. Danger. [0003] The current anti-fog products are basically liquid products made of surfactants. After spraying on the glass, paper or towel is used as a wiping tool. For such products, the anti-fog effect of a single surfactant component is limited, and the anti-fog effect of the compounded surfactant is improved, but the compatibility is often poor, resulting in spots after drying. Contents of the invention [0004] The object of the ...
