Abstract

The present invention relates to a pigment printing adhesive, in particular to a preparation method of a silicone modified pigment printing adhesive, comprising the following steps: 1) adding a first acrylate monomer into an aqueous solution of an emulsifier, Then add ammonium bicarbonate aqueous solution and sodium persulfate aqueous solution, keep warm for 1‑1.5h to obtain a pre-emulsion; 2) add the second acrylate monomer and allyltrimethylsilane to the emulsifier aqueous solution, react dropwise into the pre-emulsion In the emulsion, a silane-modified acrylate emulsion was obtained; 3) using poly(N-(4-vinylbenzyl)-N,N-dialkylamino) and polyhydroxyethylacrylamide to obtain a silane-modified acrylate Grafted and coated to obtain a pigment printing adhesive, the invention has better stability, heat resistance and air permeability, and the softness is also significantly increased, and can provide excellent lubricity while resisting bacterial adhesion, Greatly increased the friction resistance of the material.

Description

technical field [0001] The invention relates to a pigment printing adhesive, in particular to a preparation method of an organosilicon-modified pigment printing adhesive. Background technique [0002] With the improvement of people's living standards, the requirements for textiles are more diversified. Pigment printing has been widely recognized for its advantages of high quality, low pollution and low energy consumption. Adhesive is the main component of pigment printing paste, and its type and dosage directly determine the quality of printed fabrics. At present, the pigment printing adhesive widely used in our country is acrylic ester polymer, which has many advantages such as strong cohesion, good film formation, and high transparency. The unity of hand feel and color fastness greatly limits the improvement of product grade. In general, increasing the amount of binder will improve the color fastness of printed fabrics, but it will make it feel harder and affect the wear...
