Embodiment 1

[0019] Production formula:

[0020]

[0021] Detailed production process:

[0022] Add 20.0% of 2-acrylamido-2-methylpropanesulfonic acid, 2.0% of acrylic acid, and 2.0% of acrylamide into a three-necked round-bottomed flask in turn, add 66.7% of deionized water, stir to dissolve, and add to 6.5% NaOH And, adjust the pH to about 6.0, protect it with nitrogen, and slowly raise the temperature to 65°C. At this time, slowly add the initiator ammonium persulfate aqueous solution 0.5% ammonium persulfate + 1.3% deionized water, drop it in 10 minutes, and the reaction system begins to occur Polymerization reaction releases heat, the temperature of the reaction system rises, the heating is stopped, and after the temperature drops to a constant temperature of 70°C, the reaction is heated and kept for 2.0 hours, and the product is cooled to room temperature to obtain a light yellow transparent viscous liquid.

Embodiment 2

[0024] Production formula:

[0025]

[0026]

[0027] Detailed production process:

[0028] Add 22.5% of 2-acrylamido-2-methylpropanesulfonic acid, 3.0% of acrylic acid, and 3.0% of acrylamide into a three-necked round-bottomed flask in turn, add 61.95% of deionized water, stir to dissolve, and add to 7.5% NaOH And, adjust the pH to about 6.5, protect it with nitrogen, and slowly raise the temperature to 70°C. At this time, slowly add the initiator ammonium persulfate aqueous solution 0.75% ammonium persulfate + 1.3% deionized water, drop it in 15 minutes, and the reaction system begins to occur Polymerization reaction releases heat, the temperature of the reaction system rises, the heating is stopped, and after the temperature drops to a constant temperature of 75°C, the reaction is heated and kept for 3.0 hours, and the product is cooled to room temperature to obtain a light yellow transparent viscous liquid.

Embodiment 3

[0030] Production formula:

[0031]

[0032] Detailed production process:

[0033] Add 25.0% of 2-acrylamido-2-methylpropanesulfonic acid, 4.0% of acrylic acid and 4.0% of acrylamide into a three-necked round-bottomed flask in turn, add 51.7% of deionized water, stir to dissolve, and add to 9.0% NaOH And, adjust the pH to about 7.0, protect it with nitrogen, and slowly raise the temperature to 75°C. At this time, slowly add the initiator ammonium persulfate aqueous solution 1.0% ammonium persulfate + 1.3% deionized water, drop it in 20 minutes, and the reaction system begins to occur Polymerization reaction releases heat, the temperature of the reaction system rises, and the heating is stopped. After the temperature drops to a constant temperature of 75°C, the reaction is heated and kept for 4.0 hours, and the product is cooled to room temperature to obtain a light yellow transparent viscous liquid.

Abstract

The invention relates to the technical field of dyeing and finishing, and relates to a universal digital inkjet printing primer and a preparation method thereof. The raw materials for the preparation of the universal digital inkjet printing primer include deionized water, 2-acrylamido-2-methylpropanesulfonic acid, acrylic acid, acrylamide, sodium hydroxide and initiator; wherein, By weight, the proportion of the 2-acrylamido-2-methylpropanesulfonic acid is 15%-30%, the proportion of the acrylic acid is 1%-5%, and the proportion of the acrylamide is 1%-5%, the proportion of the sodium hydroxide is 3%-10%, the proportion of the initiator is 0.1%-10%, and the balance is deionized water. The invention solves the defect that the sizing treatment agent for digital printing in the prior art forms sizing spots due to poor fluidity, and obtains a low-cost and high-performance general-purpose digital ink-jet printing primer.

Description

technical field [0001] The invention relates to the technical field of dyeing and finishing, in particular to a general-purpose digital ink-jet printing primer and a preparation method thereof. Background technique [0002] Most of the existing digital printing sizing agents on the market are specialized. There are different digital printing sizing agents for different dyes and textile materials. Printing sizing treatment agent; In addition, almost all digital printing sizing treatment agents currently on the market are replaced by traditional printing aleurone, which requires chemicals and stirring for 12 hours or even longer, which brings great inconvenience to the factory. It is very inconvenient; the release of traditional printing aleurone to replace the digital sizing treatment agent can only meet the basic requirements of modern digital printing technology, but cannot meet the high-quality requirements of digital printing. For example, the color is light, the clarity...
