Problems solved by technology

[0004] The technical problem to be solved in the present invention is: the problem of poor weather resistance of dye molecules. For this problem, the present invention first uses carboxylated porous polystyrene microspheres as a carrier to prepare loaded dye particles, and adds the loaded dye particles to twelve The pigment is prepared between the layers of the mica powder modified by alkyltrimethylammonium bromide; the pigment not only has good weather resistance, but also has good affinity with fabrics. While ensuring bright patterns, the color is fast is also effectively improved

Abstract

The invention provides a kind of blue ink-jet ink of carboxylated polymer microsphere loaded disperse dye and mica powder intercalation compound, comprises the following components in parts by weight: 20-40 parts of colorant, 15-25 parts of ethanol, 0.1-0.45 parts of surfactant, 0.1-0.5 parts of pH regulator, 0.35-0.66 parts of humectant; 20-50 parts of deionized water; the colorant is a coating of disperse blue dye; disperse blue dye is loaded on carboxyl porous polystyrene microsphere surface, and then dispersed between the sheets of the organic mica powder; the surfactant is sodium dodecylbenzenesulfonate, sodium laurylsulfate, sodium ligninsulfonate, One of alkylphenol polyoxyethylene ether and sulfamic acid; the pH regulator is one of triethanolamine, ammonia water, sodium citrate, sodium tartrate, sodium carbonate, and potassium carbonate. The invention also discloses a preparation method of the blue inkjet ink. The ink-jet ink prepared by the invention has good stability, can obtain brightly colored patterns when used for fabric ink-jet printing, and has high color fastness.

Description

technical field [0001] The invention relates to the field of ink preparation for ink-jet printing, in particular to a blue ink-jet ink in which carboxylated polymer microspheres are loaded with disperse dyes and mica powder for intercalation compounding. Background technique [0002] Printing is not only a means of information retention, but also a sign of technological progress. With the rapid development and popularization of personal computers, digital printing technology has developed rapidly, especially inkjet printing has the advantages of wide adaptability, high intelligence, low cost, and no pollution. With the development of computer control technology and packaging technology Continuous development and rapid development, and has been widely used. Inkjet printing is controlled by a computer, and the ink is sprayed from the nozzle onto the substrate to obtain a pressureless printing of text and images. The raw material of inkjet printing technology determines that ...
