Abstract
The invention discloses energy-saving LOW-E glass, and aims to solve the problem that the LOW-E glass cannot meet the use requirements of more markets. The key points of the technical scheme are as follows: the glass sheet comprises a glass sheet, a first bottoming dielectric layer silicon nitride layer, a second titanium oxide layer, a third protective layer nickel-chromium layer, a fourth functional layer silver layer, a fifth metal protective layer nickel-chromium layer, a sixth zinc oxide layer, a seventh silicon nitride layer and an eighth graphite protective layer, wherein the first bottoming dielectric layer, the second titanium oxide layer, the third protective layer nickel-chromium layer, the fourth functional layer silver layer, the fifth metal protective layer nickel-chromium layer, the sixth zinc oxide layer, the seventh silicon nitride layer and the eighth graphite protective layer are sequentially plated on the glass sheet, and the glass sheet is prepared from the following raw materials in percentage by weight: cesium tungsten bronze (cs0.3wo3): 7.77 percent; tungstic acid (H2 WO 4): 9.85 percent; boric acid (H3 BO 3): 49.10 percent; silica (SiO 2): 20.79 percent; sodium fluoride (NaF): 11.81 percent; antimony trioxide (Sb 2O 3): 0.67 percent. According to the invention, tungsten bronze or low-valence tungsten oxide is used as a raw material, so that the cost is greatly reduced compared with the cost of the current commercial energy-saving coated glass or ITO and the like, and the low-valence tungsten bronze or ITO has a strong near-infrared shielding effect after 950nm and a good energy-saving effect.
Description
Technical Field
The invention relates to the technical field of glass, in particular to energy-saving LOW-E glass and a preparation method thereof.
Background
Most of building energy consumption is lost through doors and windows, and the novel LOW-radiation LOW-E glass has higher visible light transmittance, ensures good natural lighting, can effectively control the transmission of solar thermal radiation, can reflect near and far infrared thermal radiation back, can be used in any climatic environment, and can achieve the purposes of controlling sunlight, saving energy and controlling and adjusting heat.
As long as the low-radiation glass is installed, the air conditioner cost of little indoor flower can always maintain the situation of being warm in winter and cool in summer, namely, the heat-proof energy enters the room in summer and leaks in winter, thereby having excellent bidirectional energy-saving effect, and being capable of blocking ultraviolet irradiation and enabling the color of the furniture not to change. Because the LOW-radiation coated glass has excellent energy-saving effect, the LOW-radiation LOW-E glass can be used as one of the main building materials of large buildings instead of cement wall bricks, so that an energy-saving transparent glass coat is covered for removing thick wall bricks of the large buildings, and a new green choice is provided for architectural designers. With the accelerating urbanization in China, the large-scale emergence of residences and commercial buildings all over the country, the energy-saving glass has become a new favorite in the building market.
Through the requirements of national laws and regulations in recent years and the popularization of some manufacturers, the capacity and the actual yield of the coated glass are continuously increased and are close to 1 hundred million m 2 More and more energy-saving glass enters common civil buildings and is used as a common building of a high-grade building, the external glass of the high-grade building is changed from common Low-emissivity glass to high-performance Low-E glass with better energy conservation, the using amount of the high-performance Low-E glass is continuously increased, and more high-performance Low-E glass is applied to the buildings.
The single-silver Low-E glass commonly used in China at present cannot completely meet the market demand, high-performance double-silver Low-E glass gradually enters the market only recently, double-silver Low-E glass is used as a high-end product of energy-saving glass, the technical difficulties in the aspects of heavy angle color deviation, coating uniformity, ex-situ toughening property and the like exist due to high product production technical difficulty, the yield and the production efficiency of double-silver Low-E are Low, the production cost is high all the time, and the application of the high-performance Low-E glass is limited to a certain degree. In view of the above, an improved single-silver Low-E glass appears in the market, and the energy-saving performance of the product is higher than that of the common single-silver Low-E glass in the market and lower than that of the common double-silver Low-E glass.
The production of the glass can avoid the problems encountered by double-silver Low-E glass, the energy-saving performance is close to that of the double-silver Low-E glass, the lower production cost and the higher production efficiency become new hot spots in the energy-saving glass market, however, the common improved single-silver Low-E glass has a simple film system result, the visible light transmittance of the product is sacrificed for achieving the higher energy-saving performance, the lighting effect of the glass is reduced by the lower visible light transmittance, the glass has a small-range application market only in southern areas with sufficient sunlight, the application of the improved single-silver Low-E is limited to a certain extent, and the improved Low-E glass has the advantages of Low cost and high energy-saving performance, and the improved single-silver Low-E glass still has better development potential in the field of the improved single-silver Low-E glass products.
