Glass printing technology with gradually-changing effect

Abstract

The invention discloses a glass printing technology with a gradually-changing effect. The glass printing technology includes the following steps that firstly, a UV coating is used for conducting silk printing on a glass material to form patterns; secondly, the material obtained after silk printing is placed on a magnet plate for 3 min to 5 min of standing; thirdly, the patterns on the materials are subjected to full curing through ultraviolet light; and fourthly, silk printing or brushing of thermosetting metal printing ink is conducted on the cured patterns, and baking is conducted for 5 min to 6 min under the temperature of 150 DEG C to 170 DEG C; and silk printing or brushing of sealing bottom paint is conducted on the surface of a cured metal printing ink layer, and baking is conducted for 7 min to 10 min under the temperature of 175 DEG C to 200 DEG C. In the above technology, a UV coating used in the above technology is the UV coating containing iron powder. The UV coating to which the iron powder is added and a matched technology are adopted in the technological method, so that the technology meets the requirement for industrial production; meanwhile, high-quality three-dimensional gradually-changing patterns conforming to the high-end market can be prepared as well, the adhesion force of the patterns to the surface of the glass material is good, the technology cost is low, and an existing multi-layer overprinting technology can be completely replaced.

Description

technical field [0001] The invention relates to a glass product with a gradient decorative effect on the surface, in particular to a process for preparing a glass product with a gradual decorative effect. Background technique [0002] The process of using ordinary UV ink to produce a three-dimensional gradient effect on the glass material to be processed is called "magic color effect" when selling glass products, and has a very high market economic value. In the prior art, such glass products are often obtained by screen printing. In the prior art, a multi-layer planar screen printing process is used to prepare a pattern with a three-dimensional gradient effect. The purpose is achieved by designing the screen mesh and using multi-layer printing before preparing the pattern, that is, a layer of ink is screen printed. Finally, wait for it to solidify and then screen-print a layer of ink on its surface, and then solidify. After repeated several times, a more ideal three-dimens...

Problems solved by technology

Although the ideal pattern can be obtained by using multi-layer printing, the cost increases geometrically, because not only do you need to use doubled heat to cure the UV ink, but you also need to spend a lot of money on designing the overall process flow, and propose a multi-layer New technical problems such as overprinting process, especially the need to solve the problem of interlayer adhesion between multi-layer UV overprinting layers

[0003] In view of the above-mentioned problems in the prior art, many researchers have also proposed other solutions, such as using three-dimensional transfer film, engraving patterns by other mechanical methods after printing the paint, etc. The problem of poor adhesion between the pattern and the glass material, while the engraved coating process is time-consuming, laborious and expensive, and it is currently difficult to mass-produce
