Manufacturing method for plastic plate internally provided with patterns

Abstract

The invention discloses a manufacturing method for a plastic plate internally provided with patterns. According to the method, the plastic plate is in a two-layer structure or a three-layer structure, and the patterns are printed on the inner surface of one layer of the two-layer structure or on the middle layer of the three-layer structure. The manufacturing method for the plastic plate internally provided with the patterns comprises the following steps of: firstly, printing the patterns on the inner surface of one layer of the two-layer structure or on the middle layer of the three-layer structure via high-definition inkjet; secondly, coating organic solvent glue water on the patterns; and finally, rolling and pressing the two-layer structure or the three-layer structure together via a rolling and pressing machine, and then naturally airing. Because the high-definition patterns are printed on the plastic plate by adopting a high-definition inkjet printing technology, and the plastic plate is bonded by using the organic solvent glue water, each layer of the plastic plate is not easy to fall off, and the pattern layer is not easy to discolour, fade and bleed; and moreover, the method is simple in operation and high in production efficiency.

Description

technical field [0001] The invention relates to the field of plastic plates, in particular to a method for manufacturing plastic plates with patterns inside. Background technique [0002] The processing process of the existing plastic sheet with a pattern is usually to apply an adhesive layer on a plastic sheet, then print the pattern with a silk screen printing process, then apply an adhesive layer on the pattern, and finally attach another piece on it. Plastic plates, because the pattern is located between two plastic plates, it is not easy to wear and tear during use, and can be preserved for a long time. [0003] Screen printing belongs to stencil printing, and it is called the four major printing methods together with offset printing, embossing printing, and gravure printing. Stencil printing includes transcription, engraving, inkjet and screen printing. The principle of stencil printing is: when the printing plate (the hole that can pass the ink is made on the base o...

AI Technical Summary

Problems solved by technology

Because screen printing needs to make different stencils according to different patterns, the manufacturing process of plastic sheets is complicated. Especially, for plastic sheets that require high-quality and high-definition patterns, the definition of screen-printed patterns is poor. In addition, when There are many kinds of colors to be printed, it is very difficult to use screen printing, the printing quality is not guaranteed, the operability is not strong, and gradient colors cannot be printed at the same time
