Description

Low-heat-absorption all-solid-state electrochromic laminated glass, hollow glass and automobile skylight

Technical Field

The utility model relates to a doubling glass technical field that discolours, concretely relates to low endothermic full solid-state electrochromic doubling glass, cavity glass and sunroof.

Background

The all-solid-state electrochromic glass is also called as all-solid-state EC glass, and the working principle of the all-solid-state electrochromic glass is that lithium ions enter a crystal lattice of tungsten oxide to form lithium tungstate, and the lithium tungstate has a very strong absorption effect on infrared light. In the colored state of the electrochromic glass, more than 99% of infrared light and more than 97% of visible light energy in the solar spectrum are blocked, wherein most of the blocked energy is absorbed and converted into self heat energy, so that the temperature of the electrochromic glass per se is seriously increased.

The electrochromic glazing was found to be over 90 ℃ in the tinted state at noon in the summer in the east and south of china. In order to avoid direct contact between a human body and a high-temperature object, the electrochromic glass generally adopts a combination mode of hollow glass, namely the electrochromic glass is placed outdoors to be measured, and the hollow cavity blocks high-temperature conduction and avoids human body contact.

However, in some application scenarios with thickness limitation, such as automotive glass, a laminated glass structure is often adopted, so that a new way is necessary to avoid the high temperature of the electrochromic glass due to heat absorption, and the energy-saving effect of the electrochromic glass cannot be influenced.

In the prior art, there are two technical solutions for this, the first solution: a low-radiation layer is arranged on one surface of the electrochromic glass, which is far away from the laminated back plate glass; the second scheme is shown in figure 2: and a low-radiation layer is arranged on one surface of the laminated back plate glass, which is far away from the electrochromic glass.

The first scheme has no mass production possibility, the electrochromic functional film and the low-radiation film are very easy to scratch in the processing and transportation processes, and when one piece of glass is respectively plated with the electrochromic functional film and the low-radiation film, one surface always needs to be in contact with machinery and an equipment platform, so that the appearance and the function are poor, such as scratching and the like; the second solution has the following problems: the low-radiation layer on the structure is exposed easily to scratch and corrode, and the low-radiation layer has short service life and is easy to lose efficacy; on the principle of energy conservation, the working principle of the low-radiation layer is to reflect infrared light, outdoor light firstly passes through the electrochromic functional film, the energy of the sunlight is already absorbed, and the infrared light which can be reflected by the low-radiation film subsequently is very little. Therefore, the solar energy is almost absorbed and not reflected, so that the temperature of the glass is sharply increased, the temperature can be up to 90 ℃ in summer, and a user is easily scalded.

Detailed Description

A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the electrochromic glass is located at the inner side, the laminated backplane glass 40 is located at the outer side, and the low-emissivity layer 30 is disposed at the inner side of the laminated backplane glass by means of coating, painting, and the like.

Wherein "inner" refers to the side away from the light source and "outer" refers to the side closer to the light source. In different application scenarios, different understandings should be made for the medial and lateral sides. For example, when the laminated glass is used as a hollow glass for a building, the inside is referred to as an indoor space and the outside is referred to as an outdoor space; for example, when the laminated glass is applied to a sunroof, the inner side refers to the inside of a vehicle and the outer side refers to the outside of the vehicle.

The electrochromic glass is formed by superposing a color-changing glass substrate 11 and an electrochromic functional layer 12, wherein the electrochromic functional layer is positioned on one side of the color-changing glass substrate, which is close to the laminated back plate glass.

The electrochromic functional layer is an inorganic all-solid-state continuous electrochromic functional film which is processed by a sputtering mode and contains tungsten trioxide.

The electrochromic functional layer and the low-e layer are connected by a bonding layer 20. The adhesive layer is made of transparent adhesive material, including but not limited to PVB, EVA, SGP or POE.

The laminated back plate glass and the electrochromic glass can be plate glass or curved glass.
