Film-plated glass

Abstract

The invention discloses film-plated glass. The film-plated glass comprises outer-layer glass, inner-layer glass and a heat insulation layer between the two layers of glass, wherein the heat insulation layer is a silicon oxide mesoporous film layer; a single-layer silicon-series nano film layer and a low-radiation film layer are sequentially arranged on the outer surface of the outer-layer glass from inside to outside; a glue sheet layer is arranged between the single-layer silicon-series nano film layer and the low-radiation film layer; and a graphite film-plated protection layer covers the outer surface of the low-radiation film layer. The film-plated glass is simple in structure, and easy to manufacture, has the characteristics of strong impact resistance, heat insulation, energy conservation, sound insulation, uneasiness of being scratched, low reflection rate, slight light pollution, long service life and the like, and can be widely applied to various fields.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a coated glass. Background technique [0002] Coated glass is a derivative of glass. It is coated with one or more layers of metal, alloy or metal compound films on the surface of the glass to change the optical properties of the glass to meet certain specific requirements. Coated glass can be divided into the following categories according to the different characteristics of the product: heat-reflective glass, low-emissivity glass (Low-E), conductive film glass, etc. Heat reflective glass is generally coated with one or more layers of metal or its compounds such as chromium, titanium or stainless steel on the surface of the glass to make the product rich in color, with appropriate transmittance for visible light and higher for infrared. Reflectivity, high absorption rate of ultraviolet rays, mainly used in buildings and glass curtain walls; low-emissivity glass is a film system c...

AI Technical Summary

Problems solved by technology

Heat-reflecting glass and low-emissivity glass are widely used. The existing heat-reflecting glass and low-emissivity glass are generally single-layer flat glass, which has the following disadvantages: poor impact resistance, easy to be polluted and scratched during handling and installation, and transparent Strong light, high reflectivity, high light pollution, low heat insulation and sound insulation performance, easy to fall off the coating layer and affect the service life, etc.

This invention is equipped with double-layer glass, which has a certain thermal insulation effect, but has the following disadvantages: First, there is no corresponding protective layer on the coating layer, and the glass is easily polluted and scratched during handling and installation, which affects its effect and purposes, and the coating layer is poor in acid and alkali resistance and wear resistance, thereby shortening the service life of the glass; secondly, it is difficult to tightly combine with the glass body because of the multi-layer coating layer, and the invention does not increase the adhesive layer or other tight settings. The coating layer is easy to fall off from the glass body, so that the glass loses the performance of the coating layer, which affects the service life; in addition, the invention is not equipped with related sound insulation devices, and the glass does not have sound insulation performance, which affects the quality of the space where the heat-insulating coated glass is installed. The scope of application of the glass subject to certain restrictions
