Abstract

The invention relates to the technical field of coating, in particular to corrosion-resistant glass and a preparation method thereof. The corrosion-resistant glass provided by the invention comprisesa glass substrate and a corrosion-resistant film layer arranged on the surface of the glass substrate, wherein the glass substrate comprises glass and a functional film layer arranged on the surface of the glass; the thickness of the corrosion-resistant film layer ranges from 10 nm to 2000 nm; and the corrosion-resistant film layer is an alloy comprising at least two elements of titanium, aluminum, chromium and nickel. Through combined use of the metal elements, the optical characteristics of the glass substrate can be maintained and the corrosion resistance of the glass substrate can be enhanced under the condition that the corrosion-resistant film layer is relatively thin and on the premise that the function of the functional film layer on the surface of the glass is not influenced.

Description

technical field [0001] The invention relates to the technical field of coating, in particular to a corrosion-resistant glass and a preparation method thereof. Background technique [0002] Thin film material is a new type of material with very promising application prospects. It is closely related to people's production activities. With the development of modern science and technology and thin film technology and the improvement of people's living standards, new requirements have been put forward for various performance indicators of thin film materials. , producers want to make it have good performance to adapt to various application conditions. [0003] In the traditional decorative glass coating process, although the coated film materials can meet specific functional requirements, such as color decoration, optical properties, etc., these functional film layers themselves are often not resistant to acid and alkali corrosion, which makes the film vulnerable to damage and af...
