Problems solved by technology

[0003] But the existing water-based fluorescent pigment paste has the following disadvantages: 1) The particles of the prepared dispersion system are large, and there will be aggregation and water separation after being left for a period of time ;2) The particles are not uniform, and the stability, fastness, and fluorescent effect are all reduced; 3) The precipitated paint color paste hardens at the bottom of the packaging barrel and is difficult to stir and disperse again, making it difficult to color and bring troubles to use

Embodiment Construction

[0020] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the following examples are used to describe the present invention in detail.

[0021] Water-based fluorescent pigment color paste is a commonly used pigment color paste, which needs to meet the following requirements: high pigment content, good fluidity, no caking, no precipitation, no mildew, and no coarseness after long-term storage ;The product viscosity is stable; the color strength is strong, and the color strength of the pigment slurry is controlled at (100±5)%; the color difference (△E) between batches is controlled within 0.8; the pH value is controlled at 6~8.

[0022] Based on the above-mentioned standards and requirements, the present invention is described in detail with examples.

[0023] The following calculations are based on 100 copies.

[0024]

[0025] According to the above formula composition, first add deionized water ...

Abstract

The invention relates to water-based anti-settling non-laminated fluorescent pigment paste and provides pigment printing paste applicable to pigment printing of pure cotton, polyester cotton and blended fabric. The water-based anti-settling non-laminated fluorescent pigment paste comprises the following components by weight: 2 to 20 percent of wetting agent, 1 to 20 percent of dispersing agent, 0.1 to 10 percent of stabilizing agent, 25 to 55 percent of pigment and the balance of deionized water, wherein the wetting agent is one of dibasic alcohol or condensed poly-dibasic alcohol; the dispersing agent comprises one or more of alkyl phenyl polyoxyethylene ether, disodium methylene dinaphthalene sulfonate, sodium salt or ammonium salt of an acrylic copolymer and a multi-anchor multi-chain macromolecular polymer; the stabilizing agent comprises an anti-settling stabilizing agent and a bactericide. The water-based anti-settling non-laminated fluorescent pigment paste is wide in application range, high in paste stability, not laminated, high in fluorescence, and convenient to use.

Description

technical field [0001] The invention relates to coatings, in particular to a water-based fluorescent pigment color paste. Background technique [0002] Fluorescent pigment printing paste is widely used in the field of cloth coloring and printing because of its bright color, convenient use and low pollution. It has developed rapidly at home and abroad. Fluorescent resin pigments of various colors are dispersed in water to form a stable dispersion system, that is, color paste. In the production and application of water-based fluorescent pigment paste, the traditional method uses anionic or non-ionic surfactants, wetting agents, water, etc. as carriers to disperse fluorescent pigment powder in the system and process it through physical grinding. Slurry floating substance with fineness below 5μm. [0003] However, the existing water-based fluorescent pigment paste has the following disadvantages: 1) The prepared dispersion system has large particles, and there will be aggregat...
