Abstract

The invention provides a method for manufacturing a smart light-controlled insulating window membrane, which aims to solve the problems of low efficiency for blocking ultraviolet and infrared rays, low speed of light-controlled color-changing and recovery, poor using comfortable feeling and the like in the prior art. According to the technical scheme, the method is characterized by comprising the following steps: manufacturing a first functional membrane; manufacturing a second functional membrane; combining the first functional membrane and the second functional membrane; coating a transparent wearing layer; and coating a pressure-sensitive adhesive layer and a composite release type PET membrane, wherein the top surface of a first optical PET membrane which is subjected to corona treatment or coated with a PU easy bonding layer is coated with a metal oxide insulating coating mixed with stannic oxide and antimony trichloride particles, and is coated with an intelligent light-controlled color-changing coating mixed with tungsten trioxide particles and benzopyran when the first functional membrane is manufactured; and when the second functional membrane is manufactured, an ultraviolet absorber is added in the process of forming a second optical PET membrane, or a nichrome metal insulating layer is plated to the bottom of the second optical PET membrane.

Description

technical field [0001] The invention relates to a functional film attached to a window glass, in particular to a method for making an intelligent light-controlled heat-insulating window film. Background technique [0002] At present, it is common to attach light-shielding and heat-insulating functional films to automobile window glass, glass curtains, and house glass windows, so that while using sunlight for lighting, it can reduce the radiation of ultraviolet rays and infrared rays from sunlight to the inside of the glass. , and adjust the brightness of sunlight on the inside of the glass. The traditional glass film used to reduce the ultraviolet and infrared radiation of sunlight and adjust the brightness of sunlight generally adopts colored or dark-colored films, but this method can only choose a film with a certain color scale in specific use. When the color scale is light When the color level is deep, the effect is not obvious, and the clarity of vision will be affecte...
