Abstract

The invention provides a green environment-friendly weather-proof dyestuff for paper and a preparation method thereof and relates to the technical field of paper dyestuffs. The green environment-friendly weather-proof dyestuff for paper is prepared from the following raw materials: modified starch, nanometer titania, carboxylic butadiene-styrene latex, alginic acid, sorbitol, pearlescent pigment,dispersing agent and the balance of deionized water. The formula of the raw materials of the green environment-friendly weather-proof dyestuff for paper provided by the invention is scientific; modified starch and nanometer titania are served as main ingredients of the dyestuff, so that the dyestuff is green, healthy and environment-friendly; the ratio of all the active ingredients is reasonable;dyeing is uniform and is difficult to fade; sources of raw materials are extensive; processing technology is simple and production cost is lower; after the dyestuff is printed on the paper surface, the paper sheet has an excellent pearly luster decorative effect, is high in glossiness and is bright; color fidelity is excellent; color is difficult to fade after the dyed paper sheet is used for a period of time; the dyestuff stability is high.

Description

Technical field [0001] The invention relates to the technical field of dyes for paper, and relates to a dye for green environmental protection and weather-resistant paper and a preparation method thereof. Background technique [0002] Dyes are substances that can make a certain color adhere to the fiber, and are not easy to fall off and change color. Dyes are usually soluble in water, and some of the dyes require a mordant to make the dye adhere to the fiber. The color of the dye and its affinity with the tissue are determined by the molecular structure of the dye itself. The chromophore group that produces the color and the auxochrome group that produces the affinity with the tissue jointly determine the dyeing properties of the dye. As a dye substance, in addition to the chromophore group, it also needs a auxochrome group that can ionize the compound. For example, in dye compounds, chromophoric groups are often formed by nitro (-NO2), azo (-N = N-), vinyl, etc., while acidic ...
