Problems solved by technology

However, in the laking process, there are still a small number of basic dyes that have not completed the laking reaction, which will lead to a faster combination of hydrophilic basic dyes and fibers than hydrophobic laked pigments, resulting in deeper dyeing , what is shown on the paper is the phenomenon of colored fibers that are often seen

Abstract

The invention discloses internal toning violet pigment color paste for printing and writing paper pulp with chemimechanical pulp.Color fiber problems are further worsened along with the progress of pulping technologies due to the fact that widely utilized color lake water-based pigment color paste is applied to chemimechanical pulp at present.The internal toning violet pigment color paste for the printing and writing paper pulp comprises, by weight, 20.0-22.0% of lightfast violet color lake, 8.0-10.0% of dispersing wetting agents, 2.0-3.0% of dyeing auxiliary, 10.0-15.0% of functional additives and the balance deionized water.The dyeing auxiliary is modified phospholipid with certain hydrophilicity.The internal toning violet pigment color paste has the advantages that uneven dyeing due to uneven combination speeds can be inhibited by the special dyeing auxiliary, and the color fiber problems can be thoroughly solved in procedures for manufacturing printing and writing paper with the chemimechanical pulp.

Description

technical field [0001] The invention relates to the field of papermaking pigment color paste, in particular to a purple pigment color paste for internal coloring of cultural paper pulp containing chemical mechanical pulp and a preparation method thereof. Background technique [0002] In recent years, with the advancement of pulping technology, in order to save energy and reduce costs, and increase paper bulk, the proportion of chemical thermomechanical pulp (abbreviated as CTMP) and alkaline hydrogen peroxide chemical mechanical pulp (abbreviated as APMP) in cultural paper is Continuous improvement, with the increase in the amount of chemical mechanical pulp, some uncontrollable situations have appeared in the entire papermaking system, especially the widely used color lake-based water-based pigment paste is used in chemical mechanical pulp, and the existing color fiber problem is further aggravated , Faced with the situation of discontinuing or switching to more expensive p...
