Abstract

The invention discloses a coated product, particularly automobile coated glass which can be processed by high temperature heat treatment. The coated glass is characterized in that an alloy material consisting of Ag, Y, Mg and B is used for replacing original pure Ag to be as a material of a low radiation function layer in the film structure of the coated product, after depositing the film layer, the function layer material is represented as Ag1-a-b-cYaMgbBc, wherein a+b+c is larger than 0 wt% and no larger than 9.5 wt%. Because of the use of the alloy Ag, the coated product is not easily be influenced by the environment, and in the other hand, the material cost of industrial large scale production is reduced. The use of the alloy material improves the antioxidant properties, capability of resisting tarnishing resulted from sulfuration, anti-mechanical properties, and chemical attack resistance of the function film layer in the film layers. The coated product disclosed herein is mainly used in automobile windshields.

Description

【Technical field】 [0001] The invention relates to a coated product, in particular to an automotive coated glass capable of high-temperature heat treatment. 【Background technique】 [0002] With the enhancement of people's awareness of energy saving, more and more buildings or cars will use low-emissivity coated glass or heat-reflective coated glass. increased comfort. [0003] Most of the off-line low-emissivity coated glass is produced now using pure silver as the functional film layer that reflects infrared rays. Because pure metallic silver is easy to react with sulfide gas in the air, the performance of silver is degraded, and silver is easily oxidized during high temperature heat treatment. The low-radiation function is lost. Therefore, the current production of low-radiation coated glass uses multi-layer dielectric layers to protect the silver layer. Even so, when the film layer is exposed to the atmosphere, the silver functional layer will be corroded by harmful gases...
