Method for producing frosted glass

Abstract

The invention relates to a method for producing frosted glass, which comprises the following steps: firstly, selecting original white glass sheets, jointing the two sheets, and sealing four edges by tapes; putting the glass into a weak acid pool for soaking for 2 minutes; conveying the glass into a corrosion pool for frosting; clearing the frosting liquid after the glass is frosted, and drying the glass; removing the sealing tapes at the four edges of the glass; then, adopting a silk screen to print the preliminarily designed glass pattern on one surface, air-drying the glass for 2 hours, andthen, conveying the glass into a dryer for drying; pasting a protective film on the glass surface which is not printed with the pattern; scrubbing the surface which is printed with the glass pattern with weak acid liquid; soaking the glass into the corrosion liquid for 80-120 minutes; putting the glass into a sodium hydroxide solution for cleaning; and then, conveying the glass into a cleaning and drying machine for cleaning and drying to obtain a finished product. The patterned glass which is produced by the method of the invention has uniform and fine etched depth, strong aesthetic feeling of the pattern, better quality, simple processing method and environment protection, and can greatly reduce the production cost in the production process.

Description

technical field [0001] The invention relates to a glass deep processing technology, in particular to a method for producing patterned glass by combining frosting and etching technology. technical background [0002] Since the 1990s, chemical polishing, etching and frosting of glass have been applied in the glass processing industry, and the glass deep processing technology has gradually matured, especially the acid etching method and screen printing drawing method used in the glass deep processing technology. Products processed by this method can be found everywhere, such as "texture glass", "concave glass", "milk painting glass", "non-reflective glass", etc., but with the improvement of people's spiritual and cultural life, people's demand for home decoration art Appreciation and quality requirements are also getting higher and higher. For this reason, continuous improvement of glass deep processing technology is also required to meet the needs of the market. At present, a...

Problems solved by technology

At present, although the technical process of making process pattern glass by acid etching method combined with screen printing technology has been mature, the existing technical process generally has backward process methods, high production cost, low production efficiency, and due to the use of chemical There are many materials, which makes it difficult to clean, difficult to guarantee the quality, and has great pollution to the environment

For example, the publication number CN1179899C discloses a method for producing concave-covered glass, which clarifies that the produced glass is translucent and translucent and has a good three-dimensional effect. The problem of good effect is that in the emulsification and etching process of the part of the printed pattern used in the production process, the method is too simple, the process effect is low, and the ratio of the frosting and etching solution used is not reasonable. The effect of the glass pattern is not good, and the artistic effect of luxury, atmosphere, beauty, translucence or light transmission of the glass pattern cannot be expressed.

In addition, the production quality and productio
