Problems solved by technology

[0004] The purpose of the present invention is to provide a preparation method of water transfer printing paper and water transfer printing paper, which aims to solve the problem that most of the water transfer printing papers in the existing market are printed on the same paper for the fourth to fifth times. When the surface strength of the paper starts to decrease, the technical problems of color block color shades, paper becoming soft and easy to deform appear in the subsequent printing.

Abstract

The invention is applicable to the technical field of water transfer paper manufacturing. The invention discloses a water transfer printing paper preparation method and water transfer printing paper.The water transfer printing paper preparation method includes the following steps: preparing a primer-coating coating, a surface-coating coating and a back-coating coating respectively, wherein the primer-coating coating is prepared by mixing potato starch and water; the surface-coating coating is prepared by mixing corn starch and water; the primer-coating coating is applied on the surface of a pigment coating layer of the water transfer printing paper, so as to form a primer-coating coating layer on the pigment coating layer; the surface-coating coating is applied to the surface of the primer-coating coating layer; the back-coating coating is applied to the back of the water transfer printing paper, and the water transfer printing paper is prepared. The surface-coating coating generatedby the corn starch has excellent tight connectivity having a good molecular structure after being cooled, and a layer of tough protective light film is formed on the surface of the primer-coating coating layer, so that the strength of the surface of the water transfer printing paper is greatly improved, and the requirement of multiple times of printing of complex procedures of high-end products ofdownstream customers of water transfer printing products is met.

Description

technical field [0001] The invention relates to the technical field of water transfer printing paper production, in particular to a method for preparing water transfer printing paper and the water transfer printing paper. Background technique [0002] Water transfer printing paper is a product for the purpose of realizing the transfer of graphic and text printing. Water transfer printing paper is based on special paper bottom paper. Special paper is made of different fibers into paper with special functions by paper machine. . Through three sizing processes on the surface of the paper, a pigment coating, a diaphragm adhesive layer and a dissolving adhesive layer are formed on the surface of the special paper backing paper. Both the diaphragm adhesive layer and the dissolving adhesive layer are water-soluble adhesive layers, and the dissolving adhesive layer needs to have good sliding properties. sex. After three times of gluing on the front side, it is necessary to go thro...
