Description

Technical Field

[0001] The invention relates to the technical field of coated glass, and in particular to a high-performance ultra-low emissivity neutral color coated glass and a preparation process thereof. Background Art

[0002] Neutral-colored coated glass has a high light transmittance, which can ensure sufficient light to make the room bright and comfortable. Neutral-colored coated glass can effectively block ultraviolet rays and infrared rays to control the indoor temperature and avoid overheating or overcooling. Neutral-colored coated glass can effectively prevent heat loss and reduce the frequency of use of indoor air conditioning, thereby achieving energy-saving and environmental protection effects.

[0003] Low-E glass, also known as low-radiation glass, is a film product composed of multiple layers of metal or other compounds coated on the glass surface. Generally, a silver layer is used as its functional layer. Its coating layer has the characteristics of high transmittance of visible light and high reflection of mid- and far-infrared rays, which makes it have excellent heat insulation effect and good light transmittance compared with ordinary glass and traditional architectural coated glass. Using Low-E glass to manufacture building doors and windows can greatly reduce the transfer of indoor heat energy to the outdoors caused by radiation, achieving ideal energy-saving effects. The use of Low-E glass can greatly reduce the fuel consumed for heating due to the reduction of heat loss, thereby reducing the emission of harmful gases. Low-E glass can meet the requirements of winter and summer, and can both keep warm and insulate, achieving environmental protection and low-carbon effects. The visible light transmittance of Low-E glass ranges from 0%-95% in theory, 6m mIt is difficult to achieve with white glass, the visible light transmittance represents the indoor lighting. The transmittance of Low-E glass is much higher than that of ordinary white glass. It is more transparent visually and has higher lighting. Using Low-E glass to make building doors and windows can greatly reduce the transfer of indoor heat energy to the outdoors due to radiation, achieving ideal energy-saving effects. At the same time, it can greatly reduce the fuel consumed for heating, thereby reducing the emission of harmful gases. In winter, the indoor temperature is higher than the outdoor temperature. Low-E glass can transfer less indoor heat to the outdoors, thereby achieving a thermal insulation effect. Similarly, in summer, the indoor temperature is lower than the outdoor temperature, and the outdoor heat can be transferred to the indoor as little as possible, achieving a heat-insulating effect.

[0004] However, traditional coated glass has the following disadvantages: The surface coating of traditional coated glass is relatively fragile and easily damaged by the external environment.
