Abstract

The invention discloses off-line temperable non-transparent high heat-reflective light-reflective coated glass and a preparation method thereof. The off-line temperable non-transparent high heat-reflective light-reflective coated glass comprises a glass substrate and a coating film layer; cheap silicon with low diffusion coefficient is taken as a raw material of the coating film layer directly; production cost is reduced greatly without influencing heat reflection effect, destruction of the coating film layer caused by heat treatment of the coating film layer in a toughening furnace is avoided, original thermal performance is maintained, toughening treatment of original film is realized, the obtained coated film possesses excellent heat-insulating properties, off-line subsequent further processing is realized at the same time, light transmittance can be reduced to be close to zero, and glass surface reflectivity is controlled to be about 35.

Description

technical field [0001] The invention relates to the field of glass and its preparation, in particular to an off-line toughened zero-transmission high-reflection coated glass and a preparation method thereof. Background technique [0002] The existing common off-line heat-reflective coated glass uses metal materials or metal oxide materials for the film system configuration, and the cost is relatively high. Off-line steel zero-transmission high-reflective coated glass directly uses silicon Si film layer. At present, the cost of silicon Si is very low, and the chemical properties of silicon Si are not active, have good stability, and the pinhole density is very low. The silicon Si film deposited by magnetron sputtering is dense, flat and has a high hardness. It has a very strong blocking ability for mobile ions. It does not oxidize at 1200 ° C and has good corrosion resistance. Therefore, silicon Si is used The offline steelable zero-transmission and high-reflection coated gl...
