Abstract

The invention discloses a urethane-organic silicon-acrylic ester ternary polymerization emulsion and a preparation method thereof. The preparation method comprises the following steps: A, modifying a polyurethane dispersion by using polyethersiloxanediol, and then carrying out end capping on the polyurethane dispersion through a (methyl) hydroxyethyl acrylate monomer to form an urethane-organic silicon-acrylic ester copolymer with both ends carried with unsaturated double bonds; and B, copolymerizing the obtained urethane-organic silicon-acrylic ester copolymer and an acrylic ester monomer to prepare the urethane-organic silicon-acrylic ester polymerization emulsion. The preparation method disclosed by the invention realizes that urethane and organic silicon structures are directly introduced to the molecular structure of polyacrylate, so that the acrylic ester improved through the method not only keeps the inherent advantages of polyacrylate, but also has the advantages of better dry-wet rubbing fastness and more softness in hand feeling in the coating printing finishing of a fabric by effectively utilizing the synergistic effect of two functional materials, namely polyurethane and organic silicon.

Description

technical field [0001] The invention belongs to the technical field of paint printing of textile materials, and relates to a terpolymer emulsion for preparing paint printing adhesives, in particular to a ternary copolymer emulsion of polyurethane, organic silicon and acrylate and a preparation method thereof. Background technique [0002] Chinese Patent Application No. 200310112823.5 proposes a method for preparing a polyurethane-acrylate water-dispersible resin. The resin particles are first prepared with a carboxyl-containing polyurethane prepolymer under the condition of using a nucleated ethylenic organosilicon monomer as a medium. Polyurethane prepolymer is formed after neutralization and water dispersion, after chain extension, polymerizable ethylenic monomers are added, and free radical polymerization is formed into a water-dispersed resin with a core-shell structure in the presence of an initiator; Chinese patent application number 200610096300.X A method for prepari...
