Abstract

The invention discloses a method for preparing a polyacrylate/nanometer ZnO composite coating printing binder by using a Pickering emulsion polymerization method. The method comprises the steps: mixing nanometer ZnO, allyloxy nonylphenol polyoxyethylene ether ammonium sulfate and water, and then, carrying out uniform ultrasonic treatment by using an ultrasonic pulverizer to obtain an aqueous dispersion of nanometer ZnO and allyloxy nonylphenol polyoxyethylene ether ammonium sulfate; then, adding butyl acrylate and methyl methacrylate into the aqueous dispersion and emulsifying to obtain a Pickering emulsion; carrying out free radical polymerization on the Pickering emulsion by taking ammonium persulfate as an initiator to obtain the polyacrylate/nanometer ZnO composite coating printing binder. By using the method, the defects of hot sticking and cold brittleness of polyacrylate binders can be overcome; after the prepared polyacrylate/nanometer ZnO composite coating printing binder is applied to a fabric coating printing process, the phenomena including mesh clogging and crazing cannot be caused, and a coating printed fabric has favorable color fastness.

Description

technical field [0001] The invention relates to a method for preparing a pigment printing adhesive for fabrics, in particular to a method for preparing a polyacrylate / nanometer ZnO composite pigment printing adhesive by a Pickering emulsion polymerization method. Background technique [0002] Pigment printing is the simplest and most common printing method. It uses the principle of adhesive to form a film on the surface of the fabric to adhere various pigments without affinity and reactivity to the fabric, thus giving the fabric various colors and colors. Pattern, which has the advantages of simple process, no washing after color fixing, energy saving and water saving, etc. It is suitable for various fibers and blended fabrics. Polyacrylate printing adhesives have excellent film-forming properties, adhesive properties, weather resistance and gloss and color retention, and have become the most widely used film-forming substances in textile pigment printing materials. However...
