Problems solved by technology

[0003] Traditionally printed decorative paper only has a flat effect, lacks the three-dimensional effect of solid wood, and is not very decorative, so three-dimensional lines need to be pressed out in the subsequent pressing process
In the traditional method, only the color and texture required by the customer are printed, and the wood-based panel is produced by pressing in the later stage; due to the moisture absorption and swelling of the decorative paper during the printing and impregnation process, it is difficult to achieve accurate alignment of the patterns carved on the decorative paper and the pressing template. , the texture and embossing of the manufactured wood-based panels deviate, resulting in a decline in the overall appearance quality of decorative paper products

Abstract

The invention belongs to the field of decorative paper printing, and specifically relates to an environment-friendly synchronous decorative paper and its printing process. The printing process includes: (1) material selection: selecting decorative base paper and preparing water-based ink; expansion coefficient of the decorative base paper: width 2.15‑2.75%, length 1.75‑3.75%; (2) Printing: printing with a gravure coating machine, the control printing pressure is 0.29‑0.32MPa, the ink absorption rate is 170‑180s, and the blade angle is 43‑47°. The unwinding tension is lower than the receiving tension; (3) Drying process: Send the printed paper into an oven for drying. The invention researches technical parameters such as printing speed, tension of retractable and unwinding materials, printing pressure, blade angle, oven temperature, etc., and accurately controls the expansion coefficient of decorative paper, so as to meet the manufacturing requirements of synchronous decorative paper, and suppress surface depressions and color changes with wood The natural texture changes consistently, with a strong three-dimensional sense.

Description

technical field [0001] The invention belongs to the technical field of decorative paper printing, and in particular relates to an environment-friendly synchronous decorative paper and a printing process thereof. Background technique [0002] Decorative paper is pressed and pasted on the surface of wood-based panels, which has the functions of decoration, protection, strengthening, sealing, etc., and improves the decorative effect, surface performance, service life and product added value of wood-based panels. It is widely used in panel furniture, cabinet furniture, laminate flooring, wooden door, vehicle decoration field. [0003] Traditionally printed decorative paper only has a flat effect, lacks the three-dimensional effect of solid wood, and is not very decorative. It needs to press out three-dimensional lines in the subsequent pressing process. In the traditional method, only the color and texture required by the customer are printed, and the wood-based panel is produc...
