Abstract

The invention relates to multi-film coating glass and a preparation method thereof, which comprises the following steps: A. glass selecting, cutting glass into pieces according to preset sizes, washing the glass piece, drying the glass pieces; B. coating a layer of indium oxide tin alloy film with a thickness of 28 to 48 nm on the surface of the glass pieces by a magnetron sputtering coater; C. atransition film with a thickness of 5 to 15nm being coated on the surface of indium oxide tin alloy film by a vacuum coating machine; the transition film is either a zinc sulfide film or a titanium dioxide film; D. a silver film with a thickness of 10 to 22nm being coated on the surface of the transition film by the vacuum coating machine; E. a protection film with a thickness of 40 to 70nm beingcoated on the surface of the silver film by the vacuum coating machine; the protection film is either a zinc sulfide film or a titanium dioxide film. The produced glass by employing the method has high transparency, is capable of effectively reflecting infrared and blocking ultraviolet, can fast and evenly give off heat, defrost fog and melt ice and snow under the condition of low pressure.

Description

technical field [0001] The invention belongs to the technical field of glass, and in particular relates to a multi-film coated glass, which is mainly used as an automobile windshield. Background technique [0002] Most of the windshields of automobiles are made of colorless and transparent tempered glass, which has low reflectivity to sunlight and poor heat insulation effect. In order to improve this situation, some medium and high-end automobiles begin to use coated glass. At present, the latest foreign products are ITO coated glass, ITO is the abbreviation of Indium-Tin-Oxide, its Chinese name is indium tin oxide alloy, and its coating method is magnetron sputtering, that is, using a magnetron sputtering coating machine to coat indium tin oxide alloy on glass surface. [0003] The advantages of indium tin oxide alloy coating are: strong combination with glass substrate, wear resistance, acid and alkali resistance, low temperature resistance, long service life, good functi...
