Description

Technical Field

[0001] The present invention relates to the technical field of glass, and particularly relates to a temperature-regulating glass with good visible light transmittance. Background Art

[0002] Glass is an amorphous inorganic solid material, usually made by adding a small amount of auxiliary raw materials to various inorganic minerals. It is widely used in daily life and industry and is favored for its transparency, hardness, chemical stability, and workability. With the increasing global awareness of energy conservation and environmental protection and the growing demand for a comfortable living space, industries such as architecture, transportation, and household appliances have an increasing demand for glass materials that can efficiently insulate heat and save energy. The heat insulation performance of the heat-insulating glass in the prior art is generally symmetric in two directions and cannot meet the requirements in a specific direction. For example, for a light and heat control glass, its surface has no special design for a single direction, and it usually cannot effectively achieve "one-way" infrared heat insulation. Based on this, the present invention designs a temperature-regulating glass with good visible light transmittance to solve the above problems. Summary of the Invention

[0003] Aiming at the problems existing in the prior art, the present invention provides a temperature-regulating glass with good visible light transmittance.

[0004] To achieve the above object, the technical solution adopted by the present invention is: a temperature-regulating glass with good visible light transmittance, including a glass body, and an infrared asymmetric layer connected to the glass body for conducting heat and insulating heat in different environments respectively; a rotating shaft for enabling the glass to rotate 360° is connected inside the glass body. A lubricating material is filled in the gap between the glass body and the rotating shaft.

[0005] Furthermore, the glass body is a glass substrate with high transparency and low ultraviolet transmittance, such as float glass or high-performance transparent glass.

[0006] Furthermore, the infrared asymmetric layer adopts, including but not limited to, an asymmetric diffraction grating structure, and the asymmetric diffraction grating structure is specifically characterized in that the front and back structures are inconsistent. The front of the asymmetric diffraction grating structure is a surface uniformly covered with many cylindrical (or cuboid and other regular columnar) grooves. The diameter of the cylindrical grooves is 1 - 5 μm, the height is 0.5 - 2 μm, and the center distance between adjacent cylindrical grooves is 3 - 6 μm. The back of the asymmetric diffraction grating structure is a smooth plane.

[0007] Furthermore, the asymmetric diffraction grating structure can adopt, including but not limited to, a photoresist-assisted lithography technique, and then the grating material is etched by a deep reactive ion etching method.

[0008] Furthermore, the asymmetric diffraction grating structure is a unit structure of the infrared asymmetric layer. The surface with a cylindrical (or regular column such as a cuboid) groove structure is the front of the infrared asymmetric layer, and the flat part is the back of the infrared asymmetric layer. The glass body is connected to the back of the infrared asymmetric layer.

[0009] Furthermore, the rotating shaft can be made of high-hardness materials including but not limited to carbon steel, stainless steel, high-strength plastics and composite materials, ceramic materials, etc. The gap between the rotating shaft and the glass body is filled with a lubricating material.

[0010] Furthermore, the lubricating material can be selected from including but not limited to nano lubricants, bio-based lubricating materials, etc.

[0011] Compared with the prior art, the present invention provides a temperature-regulating glass with good visible light transmittance, having the following beneficial effects:

[0012] 1. In the present invention, through the glass substrate with high transparency and low ultraviolet transmittance, while ensuring good visible light transmittance, most of the ultraviolet rays are blocked from entering. Overexposure to ultraviolet rays can cause damage to human health and material materials. The used glass substrate has a low ultraviolet transmittance, which can reduce indoor ultraviolet radiation, avoid the shortening of the service life of furniture caused by long-term exposure to strong ultraviolet radiation, and protect the human skin and eyes from ultraviolet radiation damage.

[0013] 2. In the present invention, through the infrared asymmetric layer, a good temperature-regulating effect can be achieved. Just by switching the inside and outside of the glass in different seasons, the use effect of warm in winter and cool in summer can be achieved. The transmission and reflection of infrared rays by the infrared asymmetric layer are asymmetric. The front of the infrared asymmetric layer has a high transmittance and a low reflectance for infrared rays; while the back of the infrared asymmetric layer has a low transmittance and a high reflectance for infrared rays. Since the transmittance of visible light on both the front and back is high and the reflectance is low, under the premise of not affecting normal lighting, infrared radiation can be normally conducted from the front of the structure, and will be blocked when on the back. In summer, taking the infrared asymmetric layer as the inner side of the glass can prevent outdoor heat from entering the room, and at the same time conduct the heat generated indoors to the outside, keeping the room cool. In winter, taking the infrared asymmetric layer as the outer side of the glass can prevent indoor heat from being dissipated to the outside, and conduct the outdoor heat to the inside, keeping the room warm.

[0014] 3. In the present invention, through the rotating shaft, the glass can rotate flexibly by 360°, avoiding the risk of ordinary glass falling due to loosening in the traditional installation method, improving the safety factor of the glass when used at high altitudes, and at the same time, when the glass is hit by a heavy object, it is less likely to break due to its flexibility, extending the service life of the glass.
