Problems solved by technology

[0008] The reflectance of visible light of the coated glass in the prior art is about 30%, which is nearly 20 percentage points higher than that of ordinary laminated glass of 7-9% for visible light, and it is made into automotive glass because Its high reflectance of visible light, when the sun shines on the surface of the coated glass, due to the reflection of the glass, strong reflection glare will be generated in a short distance, resulting in the so-called light pollution

Embodiment 1

[0023] A steelable low reflection coated glass, the structure of the coated glass is: glass plate / SnOx / TiOy / SixNy. It consists of SixNy film layer 1, TiOy film layer 2, SnOx film layer 3 and glass plate 4 stacked in sequence from top to bottom.

[0024] After cutting, edging, polishing, washing, and drying, the green float glass original sheet 4 with a thickness of 3.5 mm is sequentially plated with a SnOx film layer 1 with a thickness of 30 nm and a TiOy layer with a thickness of 1.5 nm by the following process method Film layer 2 and SixNy film layer 3 with a thickness of 10 nm. The specific coating preparation process is:

[0025] 1. SnOx is used as the bottom layer, and the tin oxide target of the rotating cathode is sputtered in an argon-oxygen mixture. The mixing ratio of argon and oxygen is 0-30% Ar, 100-70% O 2 ; The SnOx film layer can improve the bonding force with the glass substrate and prevent the transfer of sodium ions in the glass to the film system;

Abstract

The invention relates to temperable low-reflection coated glass and a preparation method thereof. The structure of the coated glass is glass plate / SnOx / TiOy / SixNy, namely that the surface of the glass plate is sequentially coated with a SnOx film layer, a TiOy film layer and a SixNy film layer. Compared with the prior art, the product provided by the invention has the characteristics of temperability and low reflection, and can be subjected to follow-up tempering heat treatment; the visible light reflectivity is lower than 20%, and the shading coefficient is not higher than 0.6; the reflection color of the glass surface is neutral color, and the visible light transmittance is moderate; the temperable low-reflection coated glass is acid and alkali resistant and wear-resistant, and can be applied to window glass and particularly to automobile window glass.

Description

technical field [0001] The invention relates to a coated glass, which can be used on window glass, especially automobile window glass. Background technique [0002] Auto foil is to paste a layer of film-like objects on the front and rear windshields, side windows and sunroofs of the vehicle, and this layer of film-like objects is also called solar film or heat reflective film. Its main function is to block ultraviolet rays and block some heat. At the same time, according to the one-way perspective performance of the solar film, the light-facing side of the heat-reflective film glass film has the characteristics of a mirror, and the back side can see through to achieve the purpose of protecting personal privacy. [0003] Technical conditions for motor vehicle operation safety, GB7258-2004, 11.6.4 stipulates that the driver's cab must ensure the driver's front and side vision, and the front windshield and glass other than the windshield are used for visible light transmission ...
