Problems solved by technology

However, although metal atoms have a high reflectivity, adding too much will reflect visible light, affecting the visual effect, and adding too little will make the heat insulation effect not obvious; metal oxides such as ITO and other metal oxides can absorb light energy. play a role in heat insulation

Abstract

The invention discloses a heat-insulating film and a preparation method. The invention provides an excellent heat-insulating film which can meet an optimal heat-insulating effect of heat radiation. The heat-insulating film comprises three layers from top to bottom, namely, a film protection layer, a use layer and a release layer, wherein the use layer comprises a metal hardening layer, an upper transparent film, a glue layer, a lower transparent film, a metal oxide layer and an adhesive layer from top to bottom; the film protection layer comprises a protection base film and a protection adhesive layer from top to bottom. As two layers of PET base materials are bonded together, the heat-insulating film is relatively good in elasticity vibration absorption function and good in acute impact resistance, and the result of an impact test of a 500g testing ball at the height of 100cm shows that a piece of glass needing heat insulation can be effectively prevented from collision damage.

Description

technical field [0001] The invention relates to a heat-insulating film preparation technology, in particular to a heat-insulating window film. Background technique [0002] In high temperature weather, especially in the hot summer, if you want to create a cool environment in your car or room, you can paste a layer of heat insulation film on the window that can effectively prevent sun protection. The main function of the heat insulation film is to block the heat of the sun. The spectrum of solar radiation to the earth is divided into infrared, ultraviolet, and visible light according to different wavelengths; their proportion in the solar spectrum is 53% for infrared, 3% for ultraviolet, and 3% for visible light. It accounts for 44%. Infrared rays are the main source of heat from the sun. Ultraviolet light has the shortest wavelength and the highest energy. It causes dark skin, freckles, and even skin cancer. Visible light is the only solar spectrum that can be seen by the na...
