Description

Technical Field

[0001] The present invention relates to the field of automotive dimming glass, and in particular to a light-resistant and dimmable polymer disperse dye liquid crystal skylight glass. Background Art

[0002] With the continuous development of the automobile industry, the performance of automobile skylight glass has attracted more and more attention. During the driving process of the car, the optical performance of the skylight glass has a very important impact on the heat insulation, privacy and visual experience of the driver and passengers. Therefore, the overall optical performance of automobile skylight glass has attracted more and more attention.

[0003] The optical performance indicators of the skylight glass mainly include: Visible light transmittance: refers to the light transmittance of the skylight glass for visible light, usually refers to the proportion of light within the wavelength range of 400-700nm transmitted through the skylight glass. The higher the visible light transmittance, the easier it is to transmit light, and the brighter the car is. Anti-ultraviolet performance: usually refers to the ability of the skylight glass to resist ultraviolet rays within a wavelength range of less than 400nm. Good skylight glass can effectively filter ultraviolet rays, protect passengers in the car, and prevent damage from ultraviolet rays. Heat insulation performance: refers to the heat conduction blocking ability and cooling effect of the skylight glass. The main indicator is the blocking rate of the skylight glass for infrared rays within the wavelength range of 900-2500nm. Good skylight glass can effectively maintain the temperature in the car, improve the comfort in the car, and save energy consumption of the air conditioner in the car. Reflectivity: refers to the reflective ability of the skylight glass to light. Good skylight glass can reflect part of the sunlight, resist the interference of strong light on the vehicle, and reduce sun exposure.

[0004] At present, there are mainly the following ways to implement the dimming function of car skylight glass: one is to set a reflective layer on the glass substrate, the other is to use dark glass, and in addition, in order to achieve the privacy function, polymer dispersed dye liquid crystal is used in the skylight glass to achieve the switching between the light-transmitting / non-light-transmitting states.

[0005] The main method of setting a silver layer on a glass substrate is magnetron sputtering. It is used as an infrared reflective coating to reduce the heat radiation of sunlight to the interior space of the car and thus improve thermal comfort. Since the silver layer is easy to corrode, the silver-containing layer is usually applied on the built-in side of the glass plate so that they are not in contact with the atmosphere. However, the outer glass and the inner glass are usually filled with adhesive polymers such as PVB, EVA, and SGP films. The contact between the silver layer and the adhesive layer will still lead to the rapid decomposition of the silver layer; in addition, when the silver layer is arranged on the exposed surface of the vehicle, the silver layer is sensitive to mechanical damage such as scratches. And most of the skylight glass is 3D glass, and there is a problem of high production cost when setting a reflective layer on the glass.

[0006] Using dark glass will result in a small dimming range and dark glass is more expensive to produce.

[0007] The use of PDLC in car sunroofs can achieve a privacy function. Adding dichroic dyes to liquid crystals can also adjust the color and transmittance of the sunroof, but the addition of dyes will affect the light aging resistance of the sunroof.

[0008] Therefore, it is necessary to propose an assembly solution for automobile skylight glass, so that the automobile skylight glass has the characteristics of a large dimming range and light aging resistance. Summary of the invention
