Problems solved by technology

[0002] The paint anti-active printing pastes on the market are all emulsified thickening systems, which are composed of emulsified paste, sodium alginate, etc., which are added with ammonium sulfate, adhesives, and paint color paste to make paint anti-active printing paste. There are several disadvantages in it. 1. The stability of the printing paste is poor, and it is easy to become thinner and stratified; 2. The electrolyte resistance is poor. After adding the binder and ammonium sulfate, it is easy to cause the emulsified paste to break and the viscosity of the printing paste to decrease; 3. Poor water quality, easy to seep
The above shortcomings hinder the application of paint anti-reactive printing
[0003] In the prior art, no synthetic coating anti-active printing paste technology is disclosed

Abstract

The anti-reactive printing paste for paint and the preparation method thereof of the present invention comprise 125-130 parts of acrylic acid, 13-15 parts of acrylamide, 22-24 parts of itaconic acid, and 56-60 parts of 2-acrylamide-2-methylpropanesulfonic acid. Parts are mixed, neutralized with sodium hydroxide solution, and then solution polymerized. After solution polymerization, 103-108 parts of potato starch are added for gelatinization. It has the characteristics of good placement stability, strong electrolyte resistance, and high definition of printed pattern outline.

Description

technical field [0001] The present invention relates to paint antireactive printing paste, especially the printing paste used for paint antireactive printing on cotton fabrics. It is a synthetic anti-reactive printing paste for paint, which has the characteristics of good stability on placement, strong electrolyte resistance, and high definition of printed pattern outlines. Background technique [0002] The paint anti-reactive printing pastes on the market are all emulsified thickening systems, which are composed of emulsified paste, sodium alginate, etc., which are added with ammonium sulfate, adhesives, and paint color paste to make paint anti-reactive printing paste. There are several disadvantages in it. 1. The stability of the printing paste is poor, and it is easy to become thin and stratified; 2. The electrolyte resistance is poor.
