Problems solved by technology

[0004] However, most of the film-forming agents of transparent heat-insulating coatings currently use organic substances, such as organic resins, which limit their service life, and the prepared transparent heat-insulating films are still lacking in stability, UV aging resistance, and abrasion resistance.

Abstract

The invention discloses an infrared barrier and heat insulation transparent inorganic coating, a preparation method thereof and an application. The preparation method of the transparent inorganic coating includes the steps: uniformly mixing inorganic transparent filming media, infrared barrier nano-powder, dispersing agents, leveling agents and thickening agents; adjusting pH (potential of hydrogen) of a system to range from 8 to 10; stirring materials for 4-10 hours and performing ball milling for 12-72 hours. The inorganic transparent filming media replace traditional organic resin, an infrared barrier and heat insulation transparent inorganic film prepared from the inorganic transparent filming media can remarkably improve stability, ultraviolet aging resistance and wear resistance of film materials.

Description

technical field [0001] The invention belongs to the technical field of material preparation, and in particular relates to an infrared-blocking and heat-insulating transparent inorganic coating and a preparation method and application thereof. Background technique [0002] Today's world economy is developing rapidly, but the environment on which human beings depend is deteriorating day by day, and the problem of energy consumption is becoming more and more prominent, especially the problem of energy consumption in buildings. Therefore, in recent years, in order to save energy, people have tried various measures to solve the heat insulation problem of glass. There are mainly three methods used in traditional insulating glass. One is to use magnetron sputtering and other processes to prepare filmed glass. The process is more complicated and the equipment is expensive. Most of the glass film is imported, resulting in a higher price of glass film. ; The second is to use heat ref...
