example 1

[0015] Preparation of nano-silica composite particles: Weigh 15g of nano-silica, 29.5g of water, and 29.5g of ethanol, mix well, add 5g of KH-570, adjust the pH to 8-9 with ammonia solution, and react at 40°C After 2 hours, 10 g of sodium p-styrene sulfonate and 1 g of sodium dodecyl sulfate were added, and after thorough stirring, the solution was transferred to an ultrasonic pulverizer with a power of 1100 W for 15 minutes of sonication. Then it was transferred to a water bath, heated to 65° C. at a stirring speed of 500 rpm after passing nitrogen gas for 30 minutes, and 10 g of ammonium persulfate solution with a mass fraction of 10% was added dropwise and reacted for 4 hours. The silica / polystyrene sodium sulfonate nanocomposite particles can be obtained by high-speed centrifugation and precipitation.

[0021] Preparation of nano-titanium dioxide composite particles: Weigh 30g of nano-titanium dioxide, 11g of water, and 11g of ethanol. After mixing evenly, add 6g of KH-570, adjust the pH to 8-9 with ammonia solution, and add 20g of methacrylic acid and 2g of Sodium dodecyl sulfonate, after fully stirring, transfer it to a high-speed emulsifier for emulsification for 15 minutes. Transfer to a water bath, blow nitrogen for 30 minutes, then raise the temperature to 75° C. at a stirring speed of 250 rpm, start to add 20 g of 10% sodium persulfate solution dropwise, and react for 5 hours. The titanium dioxide / polymethacrylic acid nanocomposite particles can be obtained by high-speed centrifugation and precipitation.

[0022] Take 3g of styrene-butyl acrylate copolymer (Mn=5000, styrene: butyl acrylate=3:1), add 6g of 20% ammonia water, 71g of deionized water, stir until completely dissolved, then add 20g of nanocomposite particles, The titanium dioxide / polymethacrylic acid nanoco...

Abstract

The invention relates to a preparation method of white paint ink used for textile inkjet printing and belongs to the technical fields of fine chemical industry and material science. The white paint ink used for inkjet printing provided by the invention is formed by the steps of mixing oxide/polymer nano composite particle dispersoid serving as a white colouring agent with a water-soluble cosolvent, a surface active agent and deionized water, stirring and filtering. The white paint ink prepared by adopting the preparation method provided by the invention has good dispersion stability and storage stability, and the preparation method of white pigment ink provided by the invention has the characteristics of low equipment investment, simple production process, stable product quality and the like and is suitable for mass production.

Description

technical field [0001] The invention belongs to the technical fields of fine chemical industry and material science, and in particular relates to a preparation method of white paint ink for ink-jet printing of textiles. technical background [0002] Inkjet printing is a new technology for textile printing and dyeing that integrates computer, information, new materials, fine chemicals and other multidisciplinary fields. It has the advantages of high printing precision, flexible batches, and no waste of dyes and auxiliaries. However, in the past, textile inkjet printing was mainly aimed at white fabrics. In recent years, with the increase in the printing volume of non-white fabrics, the demand for white pigment inks has also increased, and it has become one of the important colors in textile inkjet printing. [0003] Silicon oxide and titanium oxide are the main colorants of white pigment inks for textile inkjet printing, however, due to the high specificity of these pigments,...
