Problems solved by technology

[0004] However, there is currently no film that can achieve these two functions at the same time, and it is neither economical nor practical to coat the glass surface with films with two functions.
In short, the existing technology is difficult to meet the requirements of both heat insulation and self-cleaning

Abstract

The invention provides a self-cleaning heat-insulating transparent film and a preparation method thereof. The film comprises an infrared blocking agent, a self-cleaning agent, a leveling agent, an antifoaming agent and a film forming aid, wherein the self-cleaning agent coats the outer surface of the infrared blocking agent. According to the technical scheme provided by the invention, the transparent film capable of blocking heat and self-cleaning can be prepared, the transparent film can block heat of sunlight and infrared rays when being coated on the glass of automobiles and buildings, a self-cleaning effect can be achieved, and the effects of light transmission, cooling and self-cleaning of the automobile and the building are achieved in a greenization and protection manner.

Description

technical field [0001] The invention relates to a self-cleaning heat-insulating transparent film and a preparation method thereof, belonging to the technical field of films. Background technique [0002] The glass of cars and buildings can pass through the sun's rays to form a light-transmitting lighting effect. However, the sun's rays carry a lot of heat, which will cause high temperatures in confined spaces. At the same time, the glass needs to be cleaned in time, otherwise it will affect the line of sight , Translucent and beautiful. [0003] However, the heat in the infrared band of sunlight accounts for 43% of the total heat of sunlight. Therefore, if the infrared part of sunlight is filtered out, the heat brought by sunlight can be greatly reduced without affecting lighting. In addition, coating the superhydrophobic film on the glass surface can realize the self-cleaning effect of the glass. [0004] However, there is currently no thin film that can achieve these two...
