Preparation method of anti-permeation heat-stable low basis weight transfer printing base paper

Abstract

The invention relates to the technical field of papermaking, aims to solve the problems that transfer printing base paper is poor in universality and resources are wasted, and provides a preparation method of an anti-permeation heat-stable low basis weight transfer printing base paper. The preparation method comprises the following steps: (1) mixing and pulping raw material slurry and an auxiliaryagent to prepare mixed slurry; (2) sequentially carrying out white dextrin solution soaking, net part dehydration, squeezing and pre-drying on the mixed pulp to obtain raw material paper; (3) carrying out surface sizing on the raw material paper by adopting a modified hexadecyl methacrylate-N-hydroxymethyl acrylamide-styrene polymer; and (4) carrying out post-stage drying, calendaring finishing and rolling on the paper sheet subjected to surface sizing treatment to obtain a finished product. The printing base paper has the advantages of being low in basis weight, good in paper toughness, highin thermal stability, capable of preventing ink permeation, good in tensile strength and good in paper uniformity, sizing is conducted by introducing a small amount of polymer macromolecules with a good film-forming property, and the strength of low basis weight paper sheets is enhanced by combining and changing a pulping process.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for preparing low-quantity transfer printing base paper with anti-penetration and heat stability. Background technique [0002] Transfer printing is to use special thermal transfer ink to print various patterns on a special kind of paper, and then transfer the pattern to the product through temperature and pressure. This special paper in the thermal transfer process is called transfer printing paper. Transfer printing refers to the printing process in which dyes are transferred to fabrics via transfer paper. It is based on the sublimation characteristics of some disperse dyes, selects disperse dyes sublimated at 150-230°C, mixes them with the slurry to make "color ink", and then prints the "color ink" to transfer according to different design pattern requirements. paper (this is a special paper, so it is called transfer paper), and then the transfer paper printed w...

Problems solved by technology

[0005] In order to overcome the problems of poor universality of transfer printing base paper and waste of resources, the present invention provides a preparation method of anti-penetration thermally stable low quantitative transfer printing base paper. The printing base paper has low quantitative, good paper toughness and thermal stability Strong, can prevent ink penetration, good tensile strength, good paper evenness advantages, through the introduction of low-volume film-forming polymer macromolecules to carry out sizing, combined with the modification of the refining process, the original fibers are directly mixed Refining is changed to mixed refining of coniferous and broad-leaved semi-finished pulp. While increasing the fiber bonding area, try to avoid the cutting effect of fibers, reduce the generation of small broken fibers, and enhance the strength of low-weight paper sheets.
