Problems solved by technology

However, the existing packaging paper is to color the paper by coating the surface of the paper with dyes. The matching and proportioning of the components of the dyes are not ideal, the aggregation phenomenon between the pigment particles is serious, and the dispersion is difficult, which seriously affects the smoothness of the paper. degree, the decorative effect of the paper is not ideal, the paper is not glossy, the dyed paper is easy to fade after a period of use, and the colored paper feels poor and not smooth

Abstract

The invention provides a platinum pearlescent dye for paper and a preparation method thereof, and relates to the technical field of paper dye. The platinum pearlescent dye for paper is prepared from the following raw materials of modified talcum powder, modified leather leftovers, pearlescent pigment, tartaric acid, wheat starch, pearl powder, a lubricant, a thickener, a dispersant and deionized water. The platinum pearlescent dye for paper has the advantages that after the platinum pearlescent dye is printed to the surface of the paper, the color of the dyed paper is difficult to fade after use for a period of time; the surface of the paper is smooth and fine, the hand feel is good, and the paper is natural and stiff; by adding the pearlescent pigment, the color of the paper is rich and vivid, the stability is good, the levelling property is good, the platinum pearlescent effect of the paper is good, and the fidelity and depth sense of the color are good.

Description

Technical field [0001] The invention relates to the technical field of paper dyes, and relates to a platinum gold pearlescent dye for paper and a preparation method thereof. Background technique [0002] With the improvement of living standards, people pay more and more attention to aesthetics and taste, and there is more and more demand for high-end food and cosmetics packaging paper, which makes traditional packaging paper unable to meet people's needs, and the quality and color of paper are becoming more and more popular. Valued, [0003] Dye for papermaking is an engineering material that is coated on the surface of paper and can form a strong adhesion film. Paper coating is an important part of the coating process of packaging paper. It is a mixed system composed of pigment dispersions, adhesives and other additives. It not only has a decorative effect, makes the paper beautiful and beautiful, but can also affect the paper. Good protection, improve the printability of the pa...
