Problems solved by technology

At present, many foreign countries have invested huge sums of money in the research of inks for digital inkjet printing, but only a few foreign manufacturers such as BASF and CIBA sell dye-based inks for digital inkjet printing on the market, and they are expensive and adaptable. Limited, no true pigment-based digital inkjet printing inks on the market
In my country, although many scientific research units and universities such as Beijing Institute of Fashion Technology, Zhejiang University, Shanghai Dyestuff Research Institute and Shenyang Chemical Research Institute have carried out research work on digital inkjet printing inks, there is currently no independent property rights.

Embodiment 1

[0037] In a three-necked flask equipped with a reflux condensing device and a stirrer, carefully add 17.7 mL of distilled water to 10 mL of trichloromethylsiloxane and 60 mL of acetone under stirring conditions, and stir in a water bath at 50 ° C for 48 hours, and the reaction is completed Afterwards, the collected white solid was washed with acetone and filtered, and then vacuum-dried overnight at 45 ° C. The product was suspended with 20 times the weight of pyridine and stirred overnight, and the pyridine solution was poured into a mixture of an equal volume of concentrated hydrochloric acid and ice, and then The collected precipitate was washed with water until neutral, and dried under vacuum at 60° C. overnight. Thorough extraction with diethyl ether can obtain unmodified POSS; 0.025 g / mL γ-acryloyloxytrimethoxysilane (KH-570) in tetrahydrofuran solution, reacted in 35°C water bath for 72 hours. The product was poured into a 10-fold mixed solution of ice water and concent...

Embodiment 2

[0040] Same as Example 1, but the trichloromethylsiloxane was changed to trichlorophenylsiloxane, and the dosage was changed to 15 mL.

Embodiment 3

[0042] Same as Example 1, but the acryloyloxytrimethoxysilane was changed to methylvinyltrichlorosiloxane, and the concentration and dosage remained unchanged.

Abstract

A nano-ink for digital ink-jet print is prepared through preparing POSS with double bond from organic siloxane by partial hydrolysis-sealing angle method, modifying and chemically modifying the surface of organic pigment by coupling agent, copolymerizing said POSS with the disperse pigment via free radicals, to obtain poss-disperse pigment, and preparing said nano-ink. It has high thermal and chemical stability and the resistance to water and soap.

Description

technical field [0001] The invention belongs to the technical field of functional polymer materials, and in particular relates to a nano-ink for digital jet printing and a preparation method thereof. Background technique [0002] Since the 1990s, with the advancement of computer technology and the application of technologies such as electronic color separation and computer color matching in the textile printing and dyeing industry, the textile digital inkjet printing industry has developed rapidly. Since digital inkjet printing is a non-contact or direct printing technology, dyeing liquid can be sprayed on demand, and there is almost no waste of dye, and there is no waste liquid and waste water in the inkjet printing process, which is environmentally friendly and low energy consumption. Therefore, digital inkjet printing Ink printing technology has become one of the hot spots of research and development at home and abroad in recent years, and one of the key issues is the dev...
