Abstract

The invention discloses a low temperature cured acrylic ester electrostatic flocking adhesive. The low temperature cured acrylic ester electrostatic flocking adhesive comprises, by mass, 35 to 45 parts of methyl methacrylate; 0.5 to 2 parts of a hydroxymethyl free active monomer; 1 to 1.5 parts of peregal O-25, 0.5 to 2 parts of sodium dodecyl sulfate SDS, 1 to 3 parts of potassium sulfate; 0.3 to0.8 part of ethyl acrylate; 0.5 to 2.5 parts of p-methoxyphenol, 0.02 to 0.05 part of cyclopentylamine, and 20 to 45 parts of deionized water. The preparation method comprises following steps: A, emulsion preparation; and B, polymerization; an emulsion prepared in the step A is divided into two parts, one part is stored for further using, and the other part is added into a potassium persulfate aqueous solution, an obtained mixture is stirred and heated to 70 to 85 DEG C, 2.0 to 3.5h later, an obtained system is heated continuously, when the color of an obtained reaction product is changed, the stirring speed is slowed down, the left emulsion prepared in the step A is added, the potassium persulphate aqueous solution, and cyclopentamine are added, an obtained product is stirred, is subjected to constant temperature treatment for 1 to 2h, and is subjected to natural cooling, neutralizing, and filtering so as to obtain a polymer emulsion. The advantages are that the release of formaldehyde is reduced, drying time is shortened, and the curing temperature is reduced.

Description

Technical field [0001] The invention relates to a textile field, in particular to an electrostatic flocking adhesive and a preparation method thereof. Background technique [0002] Electrostatic flocking began in Germany in the 1930s, and the domestic electrostatic flocking industry only started in the 1970s. Due to its new technology, high production efficiency, and low import barriers in developed countries, my country's electrostatic flocking has developed rapidly in recent years. By the beginning of this century, there were about 300 electrostatic flocking factories nationwide, and the annual demand for electrostatic flocking glue was about 3500-4200t. At present, electrostatic flocking glue is mainly divided into two categories. One is solvent type, which has the advantage of lower curing temperature, but has the disadvantages of serious pollution and easy fire during drying; the second is emulsion type, which has the advantages of stable performance, Good flexibility, adj...
