Embodiment 1

[0018] Under normal temperature and pressure at 25°C, take 15kg of soft water, 1.27kg of fatty alcohol polyoxyethylene ether emulsifier, and 1.27kg of secondary alkyl sodium sulfonate emulsifier into the emulsification tank for 3 minutes to stir and disperse. Then, 61.12kg of butyl acrylate, 14.26kg of acrylonitrile, 3.31kg of isooctyl acrylate, and 2 minutes of stirring and dispersion were added, and 1.27kg of hydroxyethyl methacrylate, 0.64kg of itaconic acid, 0.64kg of acrylic acid, and methacrylic acid were added once more. 0.64kg of glycidyl acrylate, 0.38kg of silane crosslinking agent, and 0.2kg of ammonium persulfate were stirred for 15 minutes to prepare a pre-emulsion.

[0019] At normal temperature and pressure, add 41.67kg of soft water into the reactor, stir, and heat up to 78°C. Add 0.9kg of ammonium persulfate, and take 5% or 5kg of pre-emulsion solution and add it to the bottom of the reaction kettle at one time for pre-polymerization. After the temperature dr...

Embodiment 2

[0021] Under normal temperature and pressure at 25°C, take 14kg of soft water, 3kg of fatty alcohol polyoxyethylene ether emulsifier, and 3kg of secondary alkyl sodium sulfonate emulsifier and put them into the emulsification tank to stir and disperse for 3 minutes. Then put in 50kg of butyl acrylate, 16kg of acrylonitrile, 4kg of isooctyl acrylate, stir and disperse for 2 minutes, and then continue to put in 2kg of hydroxyethyl methacrylate, 0.7kg of itaconic acid, 0.7kg of acrylic acid, glycidyl methacrylate 0.7kg, silane crosslinking agent 0.5kg, ammonium persulfate 3.83kg, after stirring for 15 minutes, a pre-emulsion was prepared.

[0022] Under normal temperature and pressure, add 220.73kg of soft water into the reactor, stir, and heat up to 78°C. Add 0.9kg of ammonium persulfate, and take 5%, that is, 4.73kg of pre-emulsion, and add it to the bottom of the reaction kettle at one time for pre-polymerization. After the temperature dropped and returned to 82°C, the remain...

Embodiment 3

[0024] Under normal temperature and pressure at 25°C, take 18kg of soft water, 1kg of fatty alcohol polyoxyethylene ether emulsifier, and 1kg of secondary alkyl sodium sulfonate emulsifier and put them into the emulsification tank to stir and disperse for 3 minutes. Then put in 70kg of butyl acrylate, 13kg of acrylonitrile, 2kg of isooctyl acrylate, stir and disperse for 2 minutes, then continue to put in 1kg of hydroxyethyl methacrylate, 0.4kg of itaconic acid, 0.4kg of acrylic acid, glycidyl methacrylate 0.4kg, 0.1kg of silane crosslinking agent, 1kg of ammonium persulfate, and stirred for 15 minutes to prepare a pre-emulsion.

[0025] Under normal temperature and pressure, add 107.3kg of soft water into the reactor, stir, and heat up to 78°C. Add 0.9kg of ammonium persulfate, take 3% or 3.22kg of pre-emulsion and add it to the bottom of the reaction kettle at one time for pre-polymerization. After the temperature dropped and returned to 82°C, the remaining pre-emulsion was...

Abstract

The invention relates to a process for preparing an acrylic modified emulsion for preventing dye migration and sublimation. Mix with soft water in the emulsification tank for 3 to 4 minutes at a weight ratio of (1~3):(1~3):(14~18) at 15~35°C to form an initial pre-emulsion; then prepare The main monomer pre-emulsion containing butyl acrylate, acrylonitrile and isooctyl acrylate is obtained; then a stable reaction pre-emulsion is obtained; finally, an acrylic modified emulsion that prevents dye migration and sublimation is obtained. The coating adhesive prepared with acrylic emulsion that prevents dye sublimation can effectively prevent the sublimation phenomenon of easy-sublimation fabrics after coating. Therefore, the present inventor proposes a better technical process to obtain a final product of better quality, which is suitable for use as a printing paste in a textile pigment printing process.

Description

technical field [0001] The invention relates to a preparation process of a modified emulsion, in particular to a preparation process of an acrylic acid modified emulsion for preventing dye migration and sublimation. Background technique [0002] Acrylic resin paint is a synthetic resin paint with acrylate resin as the main film-forming substance. This kind of coating not only has the characteristics of light color, high transparency, full brightness, weather resistance, color retention, gloss retention, strong adhesion, corrosion resistance, hardness, flexibility, etc. Change the spelling resin to formulate a range of acrylic paints. [0003] In the printing process of textile pigment printing, it is necessary to print glue or color paste on the textile fabric through screen printing to form text patterns of various colors. At present, in pigment printing, two kinds of mucilage, acrylate emulsion or polyurethane emulsion, are generally used as film-forming materials, and v...
