Abstract

The invention provides an electrostatic flocking adhesive for a high fastness carpet and a preparation method thereof. The raw materials comprise, by weight, 3.5-4.3 parts of a reactive anionic emulsifier, 25-27 parts of a reactive nonionic emulsifier, 3.9-4.1 parts of methacrylic acid polyether phosphate ester, 0.9-1.2 parts of itaconic acid, 4.9-5.1 parts of N-hydroxymethyl acrylamide, 0.9-1.2 parts of acrylamide, 1.5-2 parts of methacrylamide ethyl ethylene urea, 3.9-4.1 parts of methacrylic acid, 2.4-2.6 parts of hydroxyethyl methylacrylate, 3.9-4.1 parts of glycidyl methacrylate, 180-185 parts of n-butyl acrylate, 50-53 parts of acrylonitrile, 47-50 parts of methyl methacrylate, 1-1.1 parts of ammonium persulfate, 0.5-0.55 part of sodium bisulfite, and 258-272 parts of deionized water; a polymer emulsion formed by the seeded emulsion polymerization is supplemented with water solution containing 24-25 parts of ammonium polyphosphate and mixed to prepare the electrostatic flocking adhesive for high fastness carpet, wherein the adhesive has good wear resistance, moisture resistance and flame resistance.

Description

technical field [0001] The present invention relates to an acrylate electrostatic flocking glue and a preparation method thereof, which is a modified acrylate polymer emulsion, especially a high-fastness electrostatic flocking glue used for electrostatic flocking carpets . Background technique [0002] Electrostatic flocking carpet is the application of electrostatic flocking technology to carpet products. The fluff is planted on the surface of the base cloth coated with flocking glue through high-voltage static electricity, dried and cured, and then the floating hair is removed, cleaned, dried, printed, and then combined with other The base material is compounded to obtain an electrostatic flocking carpet. [0003] Compared with the traditional tufted carpet, the electrostatic flocking carpet has a tight and flat carpet surface, with about 80 million independent fibers per square meter, and the density is about 10 times higher than that of ordinary carpets. It is not easy ...
