Problems solved by technology

[0003] Polystyrene film has high transparency, easy processing, low cost, and will not emit toxic hydrogen chloride and other gases when incinerated. When used on glass film, it can improve the high transparency and water resistance of glass and ensure the transmission of visible light. However, the wear resistance and corrosion resistance of polystyrene-acrylic films are poorer than those of traditional polyethylene and polypropylene, and abrasion and corrosion will occur during the preparation process. Therefore, a high-transparency low-radiation Coated glass and its preparation process are particularly important

Abstract

The invention discloses high-transmittance low-emissivity coated glass and a preparation process thereof. The low-emissivity coated glass comprises a glass substrate, a first dielectric film, a functional film and an outer dielectric film which are arranged in a stacked mode from bottom to top, the first dielectric film is composed of a tin oxide layer and a titanium dioxide layer, and the outer dielectric film is composed of a zinc oxide layer and a silicon-aluminum alloy layer; the functional film is prepared from the following raw materials by weight: polystyrene, phenol, 4-chloronitrobenzene, an anti-ultraviolet and anti-aging agent, a binding agent, a plasticizer and a dispersing agent. The polyphenyl propylene film has high transparency, is convenient to process and low in cost, doesnot emit toxic hydrogen chloride or other gases during incineration, can improve the high transparency and water resistance of the glass when being used on a glass film, ensures the visible light transmittance, is doped with polyphenol, can improve the wear resistance and corrosion resistance of the film, and the visible light transmittance of the glass is further improved.

Description

technical field [0001] The invention relates to the technical field of preparation of coated glass, in particular to a high-transmittance low-radiation coated glass and a preparation process thereof. Background technique [0002] Low-emissivity coated glass is a film product composed of multiple layers of metal or other compounds coated on the glass. The main performance of the functional film is to increase the transmittance of visible light and the high reflection performance of mid- and far-infrared rays. It has a wide range of applications in people's daily life. application. [0003] Polystyrene film has high transparency, easy processing, low cost, and will not emit toxic hydrogen chloride and other gases when incinerated. When used on glass film, it can improve the high transparency and water resistance of glass and ensure the transmission of visible light. However, the wear resistance and corrosion resistance of polystyrene-acrylic films are poorer than those of tra...
