Environment protection type pigment resin printing adhesive agent capable of self crosslinking at low-temperature, and preparation thereof

Abstract

The invention belongs to the water-base adhesive technical field, in particular to an environment-protecting pigment printing binder which auto-crosslinks in the low temperature and a preparation method thereof which includes a polymeric monomer is added into the water solution of the composite emulsifier and the sodium bicarbonate, and the mixture is stirred so as to obtain the pre-emulsion; the pre-emulsion is added into a reaction vessel in lots, a polymerization is initiated, and a styrene-acrylic emulsion base which crosslinks in the low temperature is obtained; the pH value is adjusted, a crosslinking agent is added and the needed binder is obtained. The pigment printing binder obtained by the preparation of the method does not comprise formalin, alkyl phenol polyoxyethylene ether and other harmful substances. The finished textile printing obtained by using the binder has the advantages of soft hand feeling, brilliant color, wear resistant, and high soaping fastness, etc.; the textile printing used for the cotton cloth, polyester-cotton can get better effect. The mixture of the binder and the synthetic thickener can modulate the proper textile printing pulp, and is applicable to plate printing and net-tube printing.

Description

technical field

[0001] The invention belongs to the technical field of water-based adhesives, in particular to an environment-friendly low-temperature cross-linkable pigment printing adhesive and a preparation method thereof. technical background

[0002] Pigment printing refers to the printing method that uses polymer compounds (adhesives) to form a film on the fabric and fix the pigment on the fabric. In recent years, with the development of the synthetic fiber industry, people's clothing has undergone tremendous changes, from the original fiber textiles based on natural fiber fabrics to various synthetic fibers and their blended fabrics with natural fibers. Multi-component fiber textiles, some textiles are even woven from as many as four or more fibers. Therefore, the original printing and dyeing techniques based on the affinity between dyes and fibers can no longer meet the needs of dyeing, especially printing, of various fabrics. Since the paint itself has no affinity...
