A preparation process of acrylic modified emulsion to prevent dye migration and sublimation

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...
