Abstract

The invention relates to an acrylic ester electrostatic flocking binding agent and a preparation method thereof. The acrylic ester electrostatic flocking binding agent is a polymer emulsion which is prepared from the raw materials: polyoxyethylene dodecyl alcohol (50), sodium dodecyl sulfate, itaconic acid, N-hydroxymethyl acrylamide, acyclic acid, butyl acrylate, 2-ethylhexyl acrylate, styrene, gamma-methacryloxy propyl trimethoxyl silan, epoxy resin E-44, adipic acid dihydrazide, sodium acetate, ammonium persulfate and deionized water through seeded emulsion polymerization. The acrylic ester electrostatic flocking binding agent is an epoxy resin and organic silicon resin jointly-modified acrylic ester electrostatic flocking binding agent. The product has the advantages of flexibility, cold endurance, weather resistance and thermosetting stability and particularly has prominent water resistance and adhesive force.

Description

technical field [0001] The invention relates to an electrostatic flocking adhesive and its preparation method, which is an acrylate polymer emulsion co-modified by an epoxy resin and a silicone resin, and is especially suitable for the high fastness requirements of electrostatic flocking fabrics . Background technique [0002] Electrostatic flocking products have been widely used in textiles, automotive interiors, toys and other industries due to their practical functions such as wear resistance, sealing, sound insulation, heat insulation, anti-scalding, and anti-fouling. Electrostatic flocking adhesive is one of the key materials that affect the quality of electrostatic flocking products. Electrostatic flocking adhesives can generally be divided into two types: emulsion type and solvent type. The advantage of solvent type is that the curing temperature is lower, but there are disadvantages such as serious pollution and easy fire during drying. Emulsion adhesive is the mo...
