Embodiment 1

[0022] An air-dyeing and vacuum-absorbing printing process, which includes coating transfer rubber on the surface of a mold cup, wrapping flower film paper, vacuum sealing and drying, including the following steps:

[0023] 1. First coat the outer surface of the mold cup with the substrate, and then dry the mold cup coated with the substrate to improve the firmness of the coating of the subsequent transfer printing rubber and the clearness and fullness of the pattern;

[0024] It is best to use white heat-drying paint for the base, and use a drying temperature of 150° to 180°. The drying temperature of 160° is the best, and the drying time is preferably 20 minutes. It is convenient to display and transfer through the white base. The color of the pattern printed and dyed by the printing rubber material can obviously improve the display effect of the pattern after printing.

[0025] 2. Then apply a layer of transfer printing rubber on the outer surface of the mold cup, so that t...

Embodiment 2

[0037] The difference from Example 1 is that after the outer surface of the mold cup is coated with a layer of transfer printing rubber, the mold cup coated with the transfer printing rubber can be put into a drying oven for drying treatment first, so that To allow the transfer printing rubber to firmly adhere to the outer surface of the mold cup, and then wrap the outer surface of the mold cup with the transfer printing rubber after drying in a circular wrapping pattern;

[0038]The transfer printing rubber is transparent grease rubber, the curing method of the transfer printing rubber is preferably high temperature curing, the drying temperature range of the drying furnace is 200°~300°, and the drying temperature of 240° is selected. The temperature is the best, and the drying time is preferably 30 minutes.

[0039] The beneficial effects of the present invention are: the air-dyeing and vacuum-absorbing printing process can not only quickly print and dye the mold cup pattern...

Abstract

The invention discloses a vacuum plastic-absorbing printing process for gas dyeing and printing, and the vacuum plastic-absorbing printing process comprises coating transfer-printing glue to the surface of a mould cup, packaging with heat transfer film paper, vacuum-sealing and drying. The vacuum plastic-absorbing printing process comprises the following steps of: I, coating a layer of transfer-printing glue on the outer surface of the mould cup; II, performing ring-shaped packaging of the heat transfer film paper on the outer surface of the mould cup with transfer-printing glue; III, fillingthe mould cup packaged with the heat transfer film paper into a vacuum bag, and putting the mould cup into the vacuum packaging machine to encapsulate; and IV, putting the encapsulated mould cup intoa drying oven to perform hot-air drying, and spreading printing ink patterns on the heat transfer film onto the transfer-printing glue, thereby realizing large-area coating patterns of the mould cup.The process effectively improves fitting firmness between the mould cup and the heat transfer film paper, and prevents the heat transfer film paper from a deviating problem; and moreover, a vacuum encapsulating design has an effect of plastifying the heat transfer film paper automatically, effectively improves definition and fullness of patterns, and improves the bright-colored effect of pattern color.

Description

technical field [0001] The invention relates to a mold cup printing process, in particular to an air dyeing and vacuum suction plastic printing process. Background technique [0002] Chinese patent application number CN200710020935.6; application date 2007.03.30; the Chinese invention patent disclosure of CN101032894A relates to a method of printing on a mold cup, and its processing technology is: the method adopts transfer printing paper, which includes the following steps: Firstly, attach the patterned side of the transfer printing paper to the mold cup to be printed; then heat press the transfer printing paper for 5-15 seconds; finally stop the heat pressing, and after cooling, you can get the printed cup Mold cup; although this method of printing on the mold cup can be used for pattern and color printing and dyeing on the mold cup, it also has a small transfer area through the small area heat transfer of the pattern on the printing paper to the mold cup, and The color i...
