Abstract

The invention provides an amphiphilic coreshell emulsion adhesive for textile coating dyeing and a synthesis method for the amphiphilic coreshell emulsion adhesive, belonging to the field of printing and dyeing. The amphiphilic coreshell emulsion adhesive adopts a coreshell structure; a core layer is an acrylate copolymer with a main soft monomer and a crosslinking monomer, and a shell layer is a block copolymer which takes a hard monomer as a main part and consists of an acrylate chain segment and an acrylamide chain segment. The preparation method for the amphiphilic coreshell emulsion adhesive comprises the following steps of (1) adding part of the monomers, an initiator, an emulsifier and the like into a bottle I, and copolymerizing common free radicals to prepare the core layer; (2) pumping a product into a bottle II, adding the residual hydrophobic monomer, the emulsifier, the initiator, a catalyst and a ligand, and copolymerizing a reverse atom transfer free radical to obtain a hydrophobic coreshell copolymer; and (3) adding all the hydrophilic monomers and the residual initiator into the bottle II, continuing to perform reverse atom transfer free radical copolymerization to obtain the amphiphilic coreshell copolymer with the shell layer containing the hydrophilic chain segments. The amphiphilic coreshell emulsion adhesive can be used as a coating printing adhesive; the using amount is reduced, and the phenomena of net plugging and roller sticking are reduced.

Description

technical field [0001] The invention belongs to the technical field of polymer synthesis and printing and dyeing. Specifically, it relates to an amphiphilic core-shell emulsion adhesive used for textile paint dyeing and a preparation method thereof. Background of the invention [0002] my country has become a big country in textile printing and dyeing. With the development of printing and dyeing technology, the current dyeing process has been developed to dyeing not only with dyes but also with paints. Pigment dyeing has the advantages of wide fiber adaptability, complete color spectrum, convenient color matching, small water consumption, energy saving and consumption reduction, etc., so it is widely respected in the dyeing and finishing industry. Unlike dyes, paints have no affinity with fiber fabrics, and adhesives are needed to fix the paints on the surface of the fabrics. Therefore, the preparation technology of adhesives is one of the key technologies for the developm...
