Problems solved by technology

[0002] PC and PMMA sheets can only be processed by screen printing and digital inkjet printing, but cannot achieve high-resolution images such as offset printing and gravure printing; because the ink surface is on the surface and back, it is easy to be wiped and corroded by corrosive gases Moreover, if ultrasonic welding and other processes are used for assembly, the ink surface will directly destroy and affect the visual effect of the front; in addition, as a flexible material, PET can be used for roll-to-roll offset printing and gravure printing to obtain rich, high-precision pattern

Abstract

The invention discloses a process for making a composite material by compounding PET and a board. The process comprises the following steps: 1), placing the PET coiled material on a film laminating machine, and dispensing unshaded UV glue on the board with the same width; 2), sending to the film laminating machine later and compounding with the PET coiled material, and evenly laminating the UV glue through the pressure of a rubber covered roller; 3) repeating the step 1) and step 2), until the needed layer number is obtained; and 4) curing and compounding UV, and obtaining a product. The provided process is capable of laminating and compounding the different thicknesses of the PET coiled materials and the different thicknesses of the boards, and performing the different processing steps, such as the silk-screening, glue-screening, digital spraying, hot stamping, and gravure, to the PET material before the compounding, and independently printing after the compounding. Various processes have strong compatibility.

Description

technical field [0001] The invention relates to a double-layer process for making a composite material by compounding PET and a plate. Background technique [0002] PC and PMMA sheets can only be processed by screen printing and digital inkjet printing, but cannot achieve high-resolution images such as offset printing and gravure printing; because the ink surface is on the surface and the back, it is easy to be intolerant to wiping and eroded by corrosive gases In addition, as a flexible material, PET can be used for roll-to-roll offset printing and gravure printing to obtain rich, high-precision pattern. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies in the existing single-layer decoration technology, and to provide a manufacturing process of a composite material obtained by compounding PET and a plate through offset printing or gravure printing. [0004] In order to solve the...
