Embodiment 1

[0022] A preparation method for wrinkled printing paste, comprising the following steps:

[0023] The first step: Stir 20 parts of polyurethane acrylate, 40 parts of catechol, 1 part of emulsifier, and 30 parts of deionized water at 300r / min for 20min, and then ultrasonicate the mixture for 20min at an ultrasonic power of 700W. Aqueous polyurethane acrylate emulsion was obtained. Wherein, the emulsifier is a sulfosuccinate surfactant. In other embodiments, the phenolic substance may also be at least one of o-methoxyphenol, 2-methoxy-4-methylphenol, and 1,3-benzenediol. The emulsifier can also be at least one of sodium allyl ether hydroxysulfonate and fatty alcohol modified polyethylene glycol surfactant.

[0024] The second step: Weigh 5 parts of pigment, 4 parts of dispersant and 20 parts of deionized water, pre-disperse at room temperature at a speed of 7000r / min for 20 minutes, transfer to a circulating sand mill and grind for 1 hour, the speed of the sand mill 1000r / min...

Embodiment 2

[0028] A preparation method for wrinkled printing paste, comprising the following steps:

[0029] Step 1: Stir 40 parts of urethane acrylate, 20 parts of catechol, 2 parts of emulsifier, and 20 parts of deionized water at 300 r / min for 20 minutes, then ultrasonicate the mixture for 20 minutes at an ultrasonic power of 1000 W to obtain Waterborne polyurethane acrylate emulsion. Wherein, the emulsifier is a sulfosuccinate surfactant.

[0030] The second step: Weigh 6 parts of pigment, 8 parts of dispersant and 30 parts of deionized water, pre-disperse at room temperature at a speed of 8000r / min for 20 minutes, transfer to a circulating sand mill and grind for 2 hours, the speed of the sand mill 2000r / min to obtain water-based pigment paste. Wherein, the pigment is a yellow azo condensation dye. The dispersant is naphthalenesulfonate formaldehyde condensate.

[0031] Step 3: Mix 60 parts of urethane acrylate emulsion, 30 parts of water-based pigment paste, 3 parts of water-ba...

Embodiment 3

[0034] A preparation method for wrinkled printing paste, comprising the following steps:

[0035] The first step: Stir 20 parts of polyurethane acrylate, 20 parts of phenolic substances, 1 part of emulsifier, and 60 parts of deionized water at 700r / min for 20 minutes, and then ultrasonicate the mixture for 20 minutes at an ultrasonic power of 1000W to obtain water-based Polyurethane acrylate emulsion. Wherein, the emulsifier is a sulfosuccinate surfactant.

[0036] Step 2: Weigh 8 parts of pigment, 4 parts of dispersant and 25 parts of deionized water, pre-disperse at room temperature at a speed of 8000r / min for 20 minutes, transfer to a circulating sand mill and grind for 1 hour, the speed of sand mill 1500r / min to obtain water-based pigment paste. Wherein, the pigment is a yellow azo condensation dye. The dispersant is naphthalenesulfonate formaldehyde condensate.

[0037]Step 3: Mix 55 parts of urethane acrylate emulsion, 25 parts of water-based pigment paste, 2 parts o...

Abstract

The invention discloses a wrinkling and printing color paste as well as a preparation method and application thereof. The raw material formula of the wrinkling and printing color paste comprises the following components in parts by weight: 20-40 parts of urethane acrylate, 20-40 parts of phenolic substance, 1-5 parts of an emulgator, 1-10 parts of pigment, 4-8 parts of a dispersing agent, 0.25-0.4part of an initiator, 4-6 parts of a thickening agent and a proper amount of deionized water, wherein the phenolic substance is selected from at least one of o-methoxyphnol, 2-methoxy-4-methylphenol,catechol and 1,3-benzenediol. When the prepared wrinkling and printing color paste is used, through ultraviolet irradiation, the initiator generates free radicals and initiating cross-linking and curing of oligomers, so that the coating is attached on fabrics; the wrinkling and printing color paste has the advantages of high wrinkling performance, aqueous property and environment friendliness, nopollution, low cost and simple production process.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a wrinkle printing color paste and its preparation method and application. Background technique [0002] With the development of social economy, people's requirements for the styles, colors and styles of fabrics and clothing are constantly changing and improving, especially the improvement of people's living standards, and the taste of life has been greatly improved. Clothing fabrics not only require high comfort and strong health care functions, but more importantly, the most primitive functions of clothing: beautifying people's images and improving people's outer packaging quality. At present, the popular printing methods at home and abroad include rotary screen printing, flat screen printing, rotary printing and digital printing, etc., with colorful and bright colors, which meet people's different needs for fashion and personalization. However, these print...
