Description

technical field [0001] The invention relates to the technical field of glass, in particular to a processing technology of thermochromic laminated glass. Background technique [0002] Ultraviolet UV-B in sunlight has serious harmful effects on human health. The potential risks include causing and exacerbating eye diseases, skin cancer and infectious diseases. Studies have shown that long-term exposure to strong ultraviolet radiation can cause DNA changes in cells, the function of the human immune system declines, the ability of the human body to resist diseases declines, and anti-ultraviolet radiation has long attracted people's attention. At the same time, the penetration rate of infrared rays in sunlight is large. It can be converted into heat energy. In hot summer, the indoor temperature is increased. In order to increase the indoor anti-ultraviolet function and anti-infrared, people began to study materials with photochromic effect, and color-changing glass came into bein...

Problems solved by technology

[0003] Electrochromism is a phenomenon in which the color-changing material undergoes a stable and reversible color change under the action of an applied current or electric field using optical properties such as light reflectance, transmittance, and absorption rate. Electrochromic glass has good chemical and The mechanical stability realizes the rapid transition between the transparent state and the opaque state, and the transition speed is within a few seconds, but the electrochromic interlayer belongs to the liquid crystal dimming film, and the liquid crystal is relatively expensive, and the production cost is high. Due to the difficulty in the production process between ordinary glass and the short service life of electrochromic glass, it is not conducive to the popularization and use of color-changing glass. The liquid crystal dimming film is firmly bonded between two pieces of ordinary float glass to form a

[0004] Thermochromic glass means that the color of the glass changes with the temperature of the surrounding environment. When the temperature is lower than the critical value, the glass is the same as ordinary glass and presents a transparent state. As the external environment increases, when the temperature is higher than the critical value, The color of the glass gradually becomes darker to block the entry of external sunlight. However, in the prior art, ordinary glass is sandwiched with a layer of thermochromic material. , the process of this adjustment method is slow, and the active adjustment function cannot be realized under low temperature conditions, and it has little effect on ultraviolet light and infrared light, and although the thermochromic laminated glass has a blocking effect on noise, the effect is poor, and people still It is deeply disturbed by noise and affects daily rest. The interlayer in thermochromic laminated glass is prone to bubbles during the production process. The interlayer film coated on the glass is not easy to disperse, resulting in uneven application, and poor high temperature and low temperature resistance. , and will produce static electricity, causing harm to the human body
