Problems solved by technology

The printing material needs to be placed at a high temperature of 160°C for 3 to 5 minutes to achieve the ideal foaming effect. Since the paper is exposed to high temperature for a long time, it will be seriously deformed, discolored, or even burnt. The high-temperature foaming process is not suitable for use. in paper packaging

Embodiment 1

[0022] 300g green self-drying ink (mix 150g of YS-200 self-drying yellow and 150g of YS-300 self-drying red from Dongguan Quanyin Rhenium Chemical Co., Ltd. to obtain 300g self-drying green ink.), 100g PET light Oil and 4g of low-temperature expansion microsphere foaming agent (manufacturer: Matsumoto Yushi Pharmaceutical Co., Ltd., model F-36D) were mixed, and stirred evenly to obtain a mixed material; the mixed material was screen-printed (200-mesh screen was selected, and bamboo patterns were used to make silk) screen) on the paper material, cured at 80°C (ultraviolet lamp power is 1000W*2, drying tunnel running speed is 5R / min) for 5 seconds, and green printed imitation flocking paper with bamboo pattern is obtained.

Embodiment 2

[0024] Mix 300g of yellow self-drying color ink (the model of Dongguan Quanyin Rhenium Chemical Co., Ltd. is YS-200 self-drying yellow), 300g of PET varnish and 300g of low-temperature expansion microsphere foaming agent (manufacturer: Matsumoto Yushi Pharmaceutical Co., Ltd., Model F-36D) mixed and stirred evenly to obtain the mixed material; screen-print the mixed material (select 200-mesh screen, use the chrysanthemum pattern to make the screen plate) on the paper material, and cure it at 90°C (the power of the ultraviolet lamp is 1000W*2 pieces , the speed of the drying tunnel is 5R / min) for 4.5 seconds, and the yellow printed imitation flocking paper with the chrysanthemum pattern is obtained.

Embodiment 3

[0026] Mix 300g of white self-drying ink (the model of Dongguan Quanyin Rhenium Chemical Co., Ltd. is YS-1100 self-drying white), 400g of PET varnish and 560g of low-temperature expansion microsphere foaming agent (manufacturer: Matsumoto Yushi Pharmaceutical Co., Ltd., Model F-36D) mixed and stirred evenly to obtain the mixed material; screen-print the mixed material (select 200-mesh screen, use snowflake pattern to make a screen plate) on the paper material, and cure at 100°C (ultraviolet lamp power is 1000W*2 , the speed of the drying tunnel is 5R / min) for 4 seconds, and the white printed imitation flocking paper with snowflake pattern is obtained.

Abstract

The invention discloses a process for preparing printing artificial flocking paper. The process comprises the following steps: mixing self-drying color ink, polyethylene terephthalate (PET) gloss oil and a low-temperature expansive type microsphere foaming agent and stirring uniformly to obtain a mixed material; and printing the mixed material on paper through silk screen and curing at 80 to 100 DEG C for 3 to 5 seconds to obtain the printing artificial flocking paper, wherein the mass ratio of the self-drying color ink to the PET gloss oil is from 3:4 to 3:1, and the weight of the low-temperature foaming agent is 1 to 80 percent of the total weight of the self-drying color ink and the PET gloss oil. By the process, a medium-and-low-temperature foaming material is adopted, the foaming temperature is low and the foaming time is short, a foaming effect can be realized through one-step heating of an infrared or ultraviolet drying channel of a common screen printer, and the processing requirement of paper packaging is met. Compared with a static flocking process, the process has high production efficiency, low cost and good adhesive force of a finished product, and can prepare the printing artificial flocking paper with different colors by adjusting the color of the color ink. Colorless and transparent bubbles are densely distributed on the surface of the printing artificial flocking paper prepared by the process, and an anti-counterfeit effect is achieved.

Description

【Technical field】 [0001] The invention belongs to the technical field of paper packaging, in particular to a process for preparing printed imitation flocking paper. 【Background technique】 [0002] At present, people mostly use high-temperature foaming process for paper packaging. The high-temperature foaming process is mainly completed by silk screen printing, and its main printing materials are materials that are not afraid of high-temperature deformation such as cloth. The printing material needs to be placed at a high temperature of 160°C for 3 to 5 minutes in order to achieve the ideal foaming effect. Since the paper is exposed to high temperature for a long time, it will be seriously deformed, discolored, or even burned, so the high-temperature foaming process is not suitable for use. in paper packaging. [0003] Therefore, it is of great significance and application value to develop a method that can realize printing imitation flocking in a short period of time in a ...
