Abstract

The invention provides an amphiphilic core-shell emulsion adhesive for pigment printing of textile and a preparation method thereof, and belongs to the field of printing and dyeing. The amphiphilic core-shell emulsion adhesive is of a core-shell structure, wherein the core layer is a soft monomer-based acrylate copolymer containing a crosslinking monomer; the shell layer is a hard monomer-based segmented copolymer comprising an acrylate chain section and an acrylamide chain section. The preparation method comprises the following steps: (1) adding some monomers, initiators, emulsifying agents and the like to a first bottle, and copolymerizing through common free radicals to obtain the core layer; (2) pumping the product into a second bottle, adding the rest hydrophobic monomer, emulsifying agents, initiators, a catalyst and a ligand, and carrying out reverse atom transfer radical polymerization to obtain a hydrophobic core-shell copolymer; (3) adding all hydrophilic monomers and the rest initiators to the second bottle, and continuously carrying out reverse atom transfer radical polymerization to obtain an amphiphilic core-shell copolymer of which the shell layer contains a hydrophilic chain section. The amphiphilic core-shell emulsion adhesive can be used as an adhesive for pigment printing, and has the effects of decreasing the dosage and reducing mesh clogging and roller adhering.

Description

technical field [0001] The invention belongs to the technical field of polymer synthesis and printing and dyeing. Specifically, it is an amphiphilic core-shell emulsion binder for textile pigment printing and a preparation method thereof. Background of the invention [0002] my country has become a major textile printing and dyeing country. The output of printed cloth in my country has exceeded 15 billion meters in 2010, and has declined in recent years. In 2013, the output was 13.5 billion meters. However, the improvement of production capacity and economic benefits cannot be developed simultaneously. Compared with the international level, my country's printing and dyeing products are still concentrated in the middle and low grades, and the added value of products is low. At present, the production of printed cloth mainly includes two processes of dye printing and pigment printing. Compared with dye printing, pigment printing has the advantages of low energy consumption...
