Abstract

The invention discloses a production process of a dimming film for intelligent dimming glass, and the dimming film is formed by an upper-layer ITO (indium tin oxide) conducting film, a lower-layer ITO conducting film and middle-layer high-polymer-liquid crystal mixed liquor through ultraviolet curing, and is prepared from the following components in percent by mass 10-75% of butyl methacrylate monomer as a high-polymer intermediate, 20-85% of cholesterol nonanoate as monomer liquid crystals, and 0.5-10% of polyethylene as an accelerating agent by high-speed stirring and mixing, uniform coating and ultraviolet curing. The production process has the beneficial effects that the intelligent dimming glass formed by the dimming film through adopting the interlayer production process is a novel technical building material with intelligence, environmental protection, energy conservation and convenience, the shielding performance is changed along with external voltage regulation, ultraviolet light can be effectively blocked, the heat loss can be prevented, simultaneously remote control can be realized by a plurality of means such as light control, sound control, wireless induction and the like, convenience is achieved, and the cost can be reduced by more than 50% compared with that of a product produced by adopting imported auxiliary materials.

Description

technical field [0001] The invention relates to the field of light-adjustable films for glass, and mainly relates to a production process of light-adjustable films for intelligent light-adjustable glass. Background technique [0002] Since the 1970s, research institutions in the United States and other developed countries have begun scientific research on how the light transmittance of glass can be adjusted. Mechanistically, there are a variety of technologies that can achieve the state transition of glass between transparent and opaque. But in principle, electronically controlled smart dimming glass is the most reliable, and consumes less energy, so it is relatively mature in technology and technology. The product already has a place in the market. [0003] Smart dimming glass products belong to the field of new materials and new technologies, also known as electronically controlled color-changing glass. A new type of liquid crystal material PDLC is attached to the ITO c...
