Abstract

The invention relates to a method for preparing a polyacrylic ester / nanoSiO2 coating printing adhesive by using a Pickering emulsion polymerization method. During preparation of a polyacrylic acid emulsion, the problems of poor washing fastness and poor wet rubbing fastness are caused by adding a surfactant. The method comprises the following steps: mixing and stirring nanoSiO2 sol with water, and dropwise adding methyl methacrylate, glycidyl methacrylate, butyl acrylate and acrylic acid; and raising the temperature, adding an ammonium persulfate solution, preserving heat for reacting, naturally cooling a reaction product, filtering the cooled reaction product, and discharging the filtered reaction product. The polyacrylic ester / nanoSiO2 coating printing adhesive is prepared by taking the nanoSiO2 sol, an acrylic acid monomer and the glycidyl methacrylate as raw materials through Pickering emulsion polymerization. The method has the advantages of simple process, avoidance of the use of the surfactant and environmental friendliness. Meanwhile, nanoparticles are introduced, so that a film is prevented from sticking at a high temperature.

Description

technical field [0001] The present invention relates to a kind of adhesive, be specifically related to a kind of Pickering emulsion polymerization method to prepare polyacrylate / nanometer SiO 2 Method of Pigment Printing Binder. Background technique [0002] In the printing and dyeing industry, the pigment printing process uses a polymer compound as a binder to adhere non-affinity and reactive pigments to the surface of the fiber to form the desired pattern. The process is simple, no waste water discharge, complete color spectrum, and bright colors. The pattern outline is clear, the light fastness is good, and it is suitable for various fibers and blended fabrics, so it is favored by users at home and abroad. Polyacrylic acid emulsion is a kind of pigment printing adhesive widely used. When preparing polyacrylic acid emulsion, surfactants are usually added. In the process of subsequent use, the presence of surfactants will cause poor washing fastness and wet The problem o...
