Embodiment 1

[0052] Add 2g sodium lauryl sulfate, 12g AEO9, 5g acrylic acid, 280g n-butyl acrylate, 30g styrene and 350g deionized water into the reaction vessel, stir and emulsify at 25°C for 45 minutes to prepare a pre-emulsion.

[0053] Dissolve 1.2g of ammonium persulfate in 100g of deionized water to prepare an initiator solution, then take 170g of pre-emulsion and 25g of initiator solution into a four-necked bottle, and raise the temperature to 80-82°C. When the blue light appears in the reaction emulsion, slowly add the remaining pre-emulsion and initiator dropwise, and keep warm at 82-85°C for 2.0 hours after the dropwise addition.

[0054] Then the temperature was lowered to 30°C, and a mixture of 10g of acrylic acid, 20g of n-butyl acrylate, 40g of methyl methacrylate, 30g of glycidyl methacrylate and 10g of hydroxyethyl methacrylate was added dropwise, and persulfuric acid was added dropwise. Ammonium solution (1g ammonium persulfate dissolved in 70g deionized water) and N,N,N′,...

Embodiment 2

[0062] Add 14g sodium dodecylbenzene sulfonate, 10g Pingpingjia 20, 8g methacrylic acid, 2g acrylamide, 200g 2-ethylhexyl acrylate, 50g styrene and 410g deionized water into the reaction vessel, at 40°C Stir and emulsify for 60 minutes to prepare a pre-emulsion.

[0063] Dissolve 1g of sodium persulfate in 50g of deionized water to prepare an initiator solution, then take 175g of pre-emulsion and 12.5g of initiator solution into a four-necked bottle, and raise the temperature to 80-82°C. When the blue light appears in the reaction emulsion, slowly add the remaining pre-emulsion and initiator dropwise, and keep warm at 82-85°C for 1.0 hour after the dropwise addition.

[0064] Then lower the temperature to 35°C, add dropwise a mixture of 10g methacrylic acid, 20g ethyl acrylate, 50g acrylonitrile, 20g hydroxypropyl acrylate and 10g diacetone acrylamide, and dropwise add ammonium persulfate solution (2g persulfate Ammonium dissolved in 100g deionized water) and vitamin C soluti...

Embodiment 3

[0069] Add 6g of sodium dodecyl sulfonate, 24g of Tween 80, 5g of acrylic acid, 5g of acrylamide, 240g of n-butyl acrylate, 40g of methyl methacrylate and 350g of deionized water into the reaction vessel, stir and emulsify at 35°C for 60 minutes to make a pre-emulsion.

[0070] Dissolve 1g of potassium persulfate in 50g of deionized water to prepare an initiator solution, then take 175g of pre-emulsion and 13g of initiator solution into a four-necked bottle, and raise the temperature to 80-82°C. When the blue light appears in the reaction emulsion, slowly add the remaining pre-emulsion and initiator dropwise, and keep warm at 80-82°C for 3.0 hours after the dropwise addition.

[0071] Then the temperature was lowered to 35°C, and a mixture of 5g of acrylic acid, 40g of ethyl acrylate, 40g of acrylonitrile, 10g of methacrylic acid ethylene glycol diester and 10g of N,N'-methylenebisacrylamide was added dropwise. At the same time, ammonium persulfate solution (2g ammonium persu...

Abstract

The invention relates to an environmentally-friendly pigment printing binding agent and a preparation method thereof. The preparation method includes the steps as follows: (1), monomers are provided, and include 45-85% of soft monomers, 10-35% of hard monomers, 2-7% of functional monomers, and 3-13% of cross linking monomers according to the total mass of monomers; (2), an emulsion polymerization reaction is carried out on part of soft monomers, hard monomers and functional monomers at the temperature of 60-90 DEG C and in the presence of an radical initiator; and (3), an emulsion polymerization reaction is carried out on the rest of soft monomers, hard monomers and functional monomers as well as cross linking monomers at the temperature of 25-45 DEG C, and in the presence of an intermediate product obtained in the step (2), the radical initiator and co-initiator compounds, thereby obtaining the pigment printing binding agent product. The binding agent is used for extra deep coloured printings, and solves the problem that the rubbing fastness is insufficient when the existing environmental-friendly binding agent is used for theextra deep coloured printings.

Description

technical field [0001] The invention relates to a textile paint printing adhesive, especially an environment-friendly adhesive for extra dark color paint printing and a preparation method thereof. Background technique [0002] Pigment printing has attracted more and more attention from the printing and dyeing industry because of its advantages such as simple process, complete color spectrum, energy saving and consumption reduction, and less pollution, and has been adopted by more and more printing and dyeing factories. [0003] Adhesive is the main component of pigment printing slurry, its performance directly affects the printing process of fabrics, and affects the fastness, feel and style of printed fabrics. In recent years, pigment printing has developed rapidly, and my country's pigment printing products have also increased year by year. However, related chemicals for pigment printing such as printing adhesives have not kept up with the pace of market development. Espe...
