Problems solved by technology

When writing colored ink for painting on paper, if the paper fibers have strong water absorption, the colored ink coated on the paper will be quickly absorbed by the fibers, resulting in the color of the colored ink not being able to separate out well and not being well absorbed. Reflect the color of colored ink; and due to the rapid water absorption of the fiber, the paper will be soaked and the strength of the paper will be reduced
If the water absorption of the paper is weak, the color ink will accumulate on the writing surface, which is not easy to dry, which will affect the efficiency of writing and painting
Therefore, for the writing and painting of dye-based color ink, there is a contradiction between water absorption and surface drying rate.

Abstract

The invention discloses a preparation process of color ink writing paper and the color ink writing paper. The color ink writing paper preparation process at least comprises the following steps: (1) preparing paper pulp through an alkaline method, and adding a first sizing composition into the paper pulp to obtain a mixture A; (2) adding a first filler into the mixture A to obtain a mixture B; (3) carrying out papermaking on the mixture B by using an inclined wire paper machine to obtain primary paper; and (4) coating the upper side and the lower side of the preliminary paper with mineral substance layers. The first sizing composition is added into the paper pulp and reacts with hydroxyl in cellulose, and a hydrophobic film is attached to the surface of the cellulose, so that the overall hydrophobic effect of the paper is improved, and the permeation resistance and strength of the paper are improved. By adding the first filler and arranging the mineral substance layers, the ink can not be quickly absorbed by the paper, the ink can be better subjected to chromatography, the color of the ink can be better shown, and the color on the paper can be kept for a long time and does not fade.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a preparation process of colored ink writing paper and the colored ink writing paper. Background technique [0002] Papermaking is an important invention of the working people in ancient China. Papermaking technology is divided into two forms: mechanism and manual. The mechanism is carried out continuously on the paper machine. The pulp suitable for paper quality is diluted with water to a certain concentration, and is initially dehydrated in the wire part of the paper machine to form a wet paper sheet, which is then dehydrated by pressing, and then dried into paper. By hand, a frame with bamboo screens, polyester nets or copper nets is used to copy the fibers dispersed and suspended in water into wet paper sheets, which are dehydrated by pressing, and then dried or dried into paper. [0003] With the continuous development of science and technology, people have...
