Problems solved by technology

[0004] However, due to its special physical performance requirements, the flexible coating film 3 can only be printed on the pattern by screen printing with an acrylic resin coating material.
These resin coatings are currently solvent-based coatings, and a large amount of organic solvent waste gas will be generated during production and use. In addition, most of the water transfer printing companies in China are small-scale companies, and basically they do not have sufficient and effective treatment of these organic solvents. The ability of solvent waste gas, thus also causing the industry to become a serious environment polluting industry
However, the method of screen printing is applied to form the coating film, which requires a long drying and drying time, which greatly reduces the production efficiency and increases the cost.

Abstract

The invention provides an environment-friendly composite printing paper film specially used for pasting and transferring direct printing paper, which is a composite material composed of a composite base paper with water transfer performance and a printing film layer that can be conveniently applied. After the composite material is soaked in water, the printed film layer can be separated from the composite backing paper, one side of the printed film layer is bonded to the composite backing paper, the other side of the printed film layer is used for printing patterns, and the printed paper film The surface tension of the printing side is 32‑38 dynes. Correspondingly, the present invention also provides a method for preparing the above composite printed paper film. Through special resin selection and formula combination, the present invention changes the materials used in traditional decal paper and the setting method of printing layer, and eliminates the solvent-based cover adhesive layer used in the production process of decal paper, combined with the pre-coating process of resin film. Reduce emissions and protect the environment, reduce production time, greatly reduce costs, and improve the delicacy of printing. It will bring great changes to the traditional decal printing industry.

Description

technical field [0001] The invention relates to the field of water-transfer printing decal paper, in particular to an environment-friendly composite printing paper film for paste-transfer direct printing paper and a preparation method thereof. Background technique [0002] The principle of the water transfer printing process is to print the pattern on the base paper first, and then coat a layer of flexible coating film on the surface of the base paper with the printed pattern to make the water transfer decal paper, and then put the water transfer decal paper on it. Soak in water to dissolve the hydrosol of the water transfer decal paper in water, separate the patterned flexible coating film from the backing paper, and transfer the patterned flexible coating film to the surface of the substrate to complete the water transfer printing. [0003] In the existing water transfer printing decal paper, in order to realize the complete and convenient transfer of the printed pattern f...
