Overprinting glass manufacturing method and multi-color glass product

Abstract

The invention relates to an overprinting glass manufacturing method and a multi-color glass product. The overprinting glass manufacturing method comprises the following steps: providing glass with a preset size and more than two types of ink; manufacturing a screen printing plate, coating the screen printing plate with a photosensitive material, and exposing, developing and forming a film with a required pattern; printing first ink on the surface of the glass, drying the first ink to form a first ink layer, printing second ink on the first oil layer, drying the second ink to obtain a second ink layer, repeating the printing step to form more than two ink layers, then printing a waterproof material layer on the outermost ink layer according to the required pattern, and performing drying; flushing a printed product, respectively forming the required pattern corresponding to all the layers of ink, and performing thermal treatment to prepare a finished product. The patterns on all the layers of ink are formed in one step and are precisely aligned; the pattern positions are consistent, staggering is avoided, and the patterns are tidy and attractive. Due to thermal treatment, the ink can be more firmly attached to the surface of the glass and is unlikely to decolor and durable; the overprinting glass manufacturing method can be applied to manufacturing of various multi-color glass products.

Description

Technical field [0001] The invention relates to the technical field of glass manufacturing, in particular to a method for manufacturing overprint glass and a multi-color glass product. Background technique [0002] Glass products can be seen everywhere in daily life and workplace. Common ones include architectural glass, glass products, automotive glass, and decorative glass. With the development of science and technology and the improvement of people's living standards, people pay more and more attention to the decorativeness of glass. Printing patterns on glass has become one of the mainstream products of glass, and two-color or multi-color glass products have become one of them. [0003] When making two-color or multi-color glass products, glass is printed first. Traditionally, there are paint offset printing or paint screen printing. However, this printing method is more difficult to produce two-color glass products. Traditional two-color glazed glass such as figure 1 As shown...

AI Technical Summary

Problems solved by technology

The limitation of this type of product is that the surface layer does not have the sintering function, but adheres to the surface of the underlying ink, with poor adhesion, discoloration, poor scratch resistance and other quality hazards. It can only be used as hollow products, not Applied to interlayer, monolithic and coating products
