A kind of water transfer printing paper produced by coating with multi-layer paper base material and its preparation method

Abstract

A water transfer printing paper produced via multilayer paper base coating and a production method thereof are provided. The water transfer printing paper produced via multilayer paper base coating comprises a back coating layer, a base layer, a base coating layer, a core coating layer and a surface coating layer arranged sequentially from bottom to top, the base layer is formed by stacking and combining multiple wet paper sheets, including a bottom layer, a core layer and a coating layer sequentially from bottom to top, the lower surface of the bottom layer is attached to the back coating layer, and the upper surface of the coating layer is attached to the bottom coating layer; according to the water transfer printing paper produced via multilayer paper base coating provided herein, different property characteristics are imparted to each layer of base material separately according to the requirements of water transfer printing paper upon the base material, the structure of the base layer is improved significantly, and layering is clear; the water transfer printing paper has higher stiffness and lower production cost and has improved overall performance.

Description

technical field [0001] The invention relates to the technical field of water transfer printing paper, in particular to a water transfer printing paper produced by coating a multi-layer paper base material and a preparation method thereof. Background technique [0002] The current water transfer paper is coated with a single-layer paper base of 130-170g / ㎡. Because water transfer printing paper needs to have a certain stiffness in the process of being used, otherwise it will lead to low efficiency of water transfer printing, poor printing effect or even unusable; and in the existing technical field of water transfer printing paper, The paper substrates used are usually single-layer paper bases, that is, they are all products produced through one-time papermaking. Therefore, the existing water transfer paper products often have insufficient stiffness, large dimensional deformation, and performance differences in the vertical and horizontal directions. Large, high production co...

Problems solved by technology

Because water transfer printing paper needs to have a certain stiffness in the process of being used, otherwise it will lead to low efficiency of water transfer printing, poor printing effect or even unusable; and in the existing technical field of water transfer printing paper, The paper substrates used are usually single-layer paper bases, that is, they are all products produced through one-time papermaking. Therefore, the existing water transfer paper products often have insufficient stiffness, large dimensional deformation, and performance differences in the vertical and horizontal directions. Large size, high production cost and other problems, it is necessary to further improve the overall performance of water transfer paper

In order to improve the stiffness of water transfer paper, the existing methods are usually mainly by simply increasing the weight of the paper substrate, that is, increasing its thickness, or adjusting the coating formula, or reducing the moisture content of the product. Stiffness of transfer paper, but increasing the grammage will often lead to a great increase in the cost of product preparation, which runs counter to the continuous demand for cost reduction, and the space for adjusting the coating formula and reducing the moisture content of the product is very limited. At present The actual effect is not obvious
