Abstract

The invention provides a three-silver low radiation film glass supporting subsequent processing, which is characterized in that the film layer structure of the glass comprises glass, a first base layer dielectric combination layer, a second base layer dielectric combination layer, a first blocking layer, a first Ag layer, a second blocking layer, a first interlayer dielectric combination layer, athird blocking layer, a second Ag layer, a fourth blocking layer, a second interlayer dielectric combination layer, a fifth blocking layer, a third Ag layer, a sixth blocking layer, a first upper layer dielectric combination layer, and a second upper layer dielectric combination layer. The invention also provides a process for producing the glass. The three-silver low radiation glass supporting the subsequent processing is produced by adopting a unique film layer configuration, has the performances of low radiance (less than 0.2), stable optical performance, various colors, heat resistance and weather resistance, can achieve allopatric processing and satisfy all the requirements in the subsequent processing of joint products, and can be popularized and applied to vehicle glass and civil architecture glass.

Description

【Technical field】 [0001] The invention relates to the field of special glass, in particular to a triple-silver low-emissivity film glass that can be subsequently processed. 【Background technique】 [0002] Triple-silver low-emissivity glass (also known as triple-silver LOW-E glass) is a film system product composed of multiple layers of metal or other compounds coated on the glass surface, including three layers of silver. Due to the low emissivity of the silver layer, the low emissivity glass has a high transmittance to visible light, a high reflectivity to infrared rays, and good heat insulation performance. [0003] The film structure of ordinary triple-silver low-emissivity glass produced by vacuum magnetron sputtering is generally: glass / base dielectric combination layer / first Ag layer / first barrier layer / first interlayer dielectric combination layer / second Ag layer / second barrier layer / second interlayer dielectric combination layer / third Ag layer / third barrier layer / u...

AI Technical Summary

Problems solved by technology

[0007] 1. Unable to achieve curved glass coating

[0008] Bending toughened and hot-bent glass is widely used in modern buildings and automobile windshields. Traditional off-line low-e coated glass cannot be subjected to subsequent thermal processing such as bent toughening and hot bending.

None of the existing domestic architectural coated glass production lines can coat bent tempered and hot bent glass substrates.

[0009] 2. Coating operation efficiency is low

These patches are included in the production order again to arrange production, and the patch cycle is long

[0012] 3. Glass transportation costs are high
