Technological method of printing pattern on glass

Abstract

The invention discloses a process method for printing patterns on glass. Firstly, a varnish layer is printed on the glass, and after the varnish layer is cured and dried, a white bottom oil layer is printed. After the white bottom oil layer is cured and dried, a thermal transfer printing The pattern is printed on the white primer layer. Use varnish as a primer to increase the adhesion between the ink layer and the glass surface, and then print a white primer layer to provide a thermal transfer adhesion layer, which can not only print refined pattern effects on the glass surface through thermal transfer, but also improve the quality of glass products. Appearance effect, and the overall process method is simple and easy, suitable for industrial use.

Description

technical field [0001] The invention relates to the field of glass processing, in particular to a process method for printing patterns on glass. Background technique [0002] In many glass decoration products, glass with various patterns is often used as surface decoration. For example, in the field of white goods, touch panels or panels of home appliances such as refrigerators, freezers, and air conditioners often use glass plates printed with patterns as raw materials. In the field of 3C products, glass with decorative patterns is often used as raw materials for components such as mobile phone covers and back covers. [0003] In the prior art, the printing pattern on the glass often adopts the method of screen printing directly on the glass surface, and the prefabricated pattern is directly printed on it. When the glass substrate has a large area, it is also processed by UV paint spraying. In the prior art, there is also a method of mounting the pattern on the glass surf...

Problems solved by technology

The above processing methods have their own advantages, but they have their own defects: direct screen printing, the printing effect is poor when printing fine patterns, and the performance requirements for printing glass inks are high; UV paint spraying technology, also known as computer printing in the industry Inkjet printing, because the inkjet printing pattern needs to be customized, and the quality of the ink used in the inkjet printing is high, and the composition is more complicated than that of the traditional screen printing glass ink, so the application cost is high, and the adhesion of the coating on the glass is not good; On the one hand, this process method is only suitable for flat glass products; on the other hand, the mounting patterns are limited by the raw materials, and all the obtained are relatively monotonous flat patterns, which cannot show the appearance of the printed glass surface.
