Problems solved by technology

[0004] However, due to safety considerations, the above-mentioned low-emissivity coated glass often needs to be tempered. If it is tempered after coating, due to the effect of high temperature (above 680°C), the coating layer is easily oxidized and burned, resulting in low-emissivity coating. The function of the glass is completely lost

Abstract

The low radiation coated glass capable of being toughened includes one glass base plate and successively arranged the first isolating metal film of NiCr alloy, an antireflecting film of Si3N4 or Si3N4 plus TiO2, an infrared blocking film of metal Ag, the second isolating metal film of NiCr alloy, and a protecting film of Si3N4, SnO2 plus Si3N4 or TiO2 plus Si3N4. The coated glass may be toughened or heat treated while maintaining its high performance, and has excellent heat isolating performance and high antioxidant performance.

Description

technical field [0001] The invention relates to a coated glass, in particular to a temperable low-radiation coated glass and a production method thereof. Background technique [0002] Low-E coated glass, also known as Low-E glass, is formed by coating several layers of low-E materials and other metal compound films on the surface of high-quality float glass. Low-emissivity coated glass has the following characteristics: extremely low surface emissivity, extremely high far-infrared (thermal radiation) reflectivity, which can prevent the glass from absorbing heat and heat up in the form of radiation from the film surface to dissipate heat, and can also directly reflect far-infrared heat radiation. The above two characteristics of the LOW-E film cooperate with the barrier effect of the insulating glass on the convective conduction of heat, forming a LOW-E insulating glass with an extremely low U value. It can block the transfer of heat from the hot end to the cold end, preven...
