Studies On Preparation And Properties Of Glass Antifoggant

In the cool winter or rainy season, the hot air vapor will condense on the cool glass. It will greatly reduce the glass light transmittance influence the line of sight, bring a lot of inconvenience in life. This paper bases on the work of some persons who have done some research. The study is from the original hydrone glass antifogging agent to the polymer glass antifogging agent and the TiO₂ film glass antifogging agent. The research order is incremental. The purpose is to improve the antifogging film's function. And then following the economy and environmental protection, it has found a best filling of prescription.In the polymer glass antifogging agent, a new-type antifogging agent for glass that is of lasting, nontoxic, economic and practical was prepared, and properties of the antifogging agent were studied. The result has been showed that the antifogging time is over 12 days. There is no frost on the glass surface coated by polymer glass antifogging agent at -20℃. The pH value of polymer glass antifogging agent is between 7～8,which is safe for glass but also user.TiO₂ film for glass antifogging was prepared by using sol-gel method and the auto-promoted film device. The TiO₂ film was disposed at 500℃, and then find transparent film. The prepared TiO₂ film has been studied in some aspects. The experiment results indicate that the sol has the best transparency and stability and in many days there are no dispositions. The found crystal form is anatase by using X-ray photoelectron spectroscopy.
