Embodiment Construction

[0018] The invention discloses a method for manufacturing toughened LOW-E coated glass, wherein the substrate coating adopts an off-line vacuum sputtering method. The non-metallic combustible high-content carbon is used in the coating target, and the high-content carbon target is set as the final process in the vacuum studio.

[0019] The carbon content of the non-metallic combustible high-content carbon is ≥99% (such as: pure carbon [C], graphite, etc.), and the thickness of the non-metallic combustible high-content carbon film is 20-35um.

[0020] The concrete steps of off-line vacuum sputtering method among the present invention are: glass substrate is placed on the shelf, and send into 10 -1 In a vacuum environment of the order of Pa, an appropriate amount of process gas such as inert gas Ar or reactive gas O is introduced. 2 , N 2 , and keep the vacuum stable; the target (the target can include silver, copper or tin metal or a thin film system composed of metal compound...

Abstract

The invention relates to a manufacturing method of Low-E glass, in particular to a manufacturing method of temperable Low-E coated glass. The substrate coating adopts off-line vacuum sputtering method, which is characterized in that non-metallic combustible high-content carbon is used in the coating target material, and the high-content carbon target is set as the final process in the vacuum working room. It mainly solves the technical problem that the low-e glass products produced by the off-line vacuum sputtering method cannot be directly tempered to improve the strength and safety performance of the glass due to the poor film strength. The inventive method can directly temper LOW-E coated glass.

Description

technical field [0001] The invention relates to a manufacturing method of Low-E glass, in particular to a manufacturing method of temperable Low-E coated glass. Background technique [0002] Low-E glass, also known as low-emissivity glass, is a film system product composed of multiple layers of metal or other compounds coated on the glass surface. Its coating layer has the characteristics of high transmission of visible light and high reflection of middle and far infrared rays, which makes it have excellent heat insulation effect and good light transmission compared with ordinary glass and traditional architectural coated glass. [0003] The current coating production methods of LOW-E glass mainly include online high-temperature pyrolysis deposition method and offline vacuum sputtering method. Among them, the off-line vacuum sputtering method is most commonly used. [0004] Unlike the high temperature pyrolytic deposition method, the sputtering method is offline. And acco...
