Problems solved by technology

However, the nano-silver layer in silver-based low-emissivity coated glass is easily corroded and oxidized. When used in automotive glass, it needs to be made into laminated glass, and the edge needs to be removed.
In addition, the nano-silver layer will shield electromagnetic waves and affect the signals of communication equipment such as GPS, ETC and RF in the car.

Embodiment 1

[0044] The transparent glass with a thickness of 2.0mm is cut, edged, edged, cleaned and dried in sequence to obtain the original glass of the car;

[0045] The original sheet glass of the automobile is divided into a coating area, a communication window area (a side length is a square of 140mm) and an edge sealing area (a width of 15mm);

[0046] By screen printing, high temperature silicone oil (kinematic viscosity is 320mm 2 / s; the relative density is 1.08; the flash point is 280°C) coated on the communication window area and the edge banding area to obtain a high-temperature silicone oil layer (3 μm);

[0047] By magnetron sputtering, a low-radiation film is coated on the surface of the original automobile glass coated with high-temperature silicone oil: the first dielectric layer (Si 3 N 4 Thin film, thickness is 24nm), first growth layer (Al, H co-doped AZO:H transparent conductive oxide film, Al content is 3wt%; Ar and H in the sputtering atmosphere 2 The volume flo...

Abstract

The invention relates to the technical field of automobile glass processing, in particular to a manufacturing method of the front windshield automobile coated glass. The manufacturing method providedby the invention comprises the following steps of dividing the automobile raw sheet glass into a coating area, a communication window area and an edge sealing area; coating the high-temperature silicone oil on the communication window area and the edge sealing area to obtain a high-temperature silicone oil layer; plating a low-emissivity film on the surface, coated with the high-temperature silicone oil, of the automobile raw sheet glass, and then cleaning away the low-emissivity film in the communication area and the edge sealing area to obtain the coated automobile raw sheet glass; and sequentially carrying out powder spraying, pairing, hot bending, sheet combining initial pressing and high-pressure heat treatment on the coated automobile raw sheet glass to obtain the front windshield automobile coated glass. According to the manufacturing method, the problems of corrosion and oxidation of the low-radiation film at the edge of the front windshield automobile coated glass are solved,and the smooth passing of the electromagnetic waves, such as GPS, ETC and RF, is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobile glass, in particular to a method for manufacturing a front windshield automobile coated glass. Background technique [0002] Automobile glass is the main channel for heat exchange inside and outside the car. Especially in hot summer, more than 70% of the heat entering the car through the car glass will increase the cooling energy consumption of the car air conditioner and cause poor comfort in the car. At present, because silver-based low-emissivity coated glass has high visible light transmittance and infrared reflection characteristics at the same time, it can reduce the total solar energy transmission, effectively reduce the energy consumption of automobiles and improve comfort, and is an ideal energy-saving glass product for automobiles. However, the nano-silver layer in silver-based low-emissivity coated glass is easily corroded and oxidized. When used in automotive glass, it needs to be m...
