A light-conducting and heat-insulating film and its preparation method

Abstract

The invention relates to a light-conducting and heat-insulating film and a preparation method thereof, comprising a nano-ATO layer, a flexible base material layer, a pressure-sensitive adhesive layer and a release layer that are sequentially bonded to each other, and the nano-ATO layer and the pressure-sensitive adhesive layer are Coating on both sides of the flexible base material layer by means of a coating device, the release layer is arranged on the other side of the pressure-sensitive adhesive layer, and a layer of ceramic guide layer is arranged between the flexible base material layer and the pressure-sensitive adhesive layer The ceramic guide layer is composed of silica gel and guide cermet sheets evenly distributed in the silica gel, and the guide cermet sheets are magnetized and added into the silica gel by a magnetization device. After the light-guiding and heat-insulating film prepared by the present invention is installed on the glass window, if it is necessary to adjust the light-guiding angle, a magnetic bar can be used to slide in the same direction along the glass surface, and the inside of the light-guiding and heat-insulating film The cermet sheet will be attracted to change the angle under the action of magnetism, so that the direction of light passing through the glass will be changed.

Description

technical field [0001] The invention relates to a heat-insulating film, in particular to a light-conducting and heat-insulating film and a preparation method thereof. Background technique [0002] With the development of science and technology, glass is more and more used in the construction field or the automobile industry. Glass has good light transmission, which not only makes the appearance of the building more beautiful, but also opens the sight inside. However, the good light transmission also makes the sunlight stronger and generates a lot of heat, which leads to excessive temperature in the building or inside the car, making normal activities impossible. [0003] The heat insulation film is to paste a thin film object on the vehicle body or building glass, and this thin film object is also called solar film. Its main function is to block ultraviolet rays, block part of the heat, and prevent injuries caused by sudden glass bursts, anti-glare and other situations. In...
