Problems solved by technology

[0005] But in the prior art, most of the flocking adhesives with good flocking fastness have excellent viscosity, and the fluff is firmly bonded on the base cloth, but the flocking adhesive has the defect of poor air permeability, which is not conducive to air circulation. The circulation inside and outside the flocking glue, the fluff on the flocking glue with poor air permeability cannot keep soft and plump for a long time, resulting in a hard feel of the fluff

Abstract

The invention relates to an acrylic acid and its ester flocking glue, comprising the following components in parts by weight: 10-20 parts of acrylic acid, 20-30 parts of acrylic esters, 20-30 parts of polyoxyethylene hydrogenated castor oil, 0.5-1 part of lauryl sulfate 0.3~0.8 parts of sodium, 0.2~0.5 parts of azo initiator, 40~60 parts of water. The flocking glue prepared by the invention has excellent air permeability, is beneficial to the circulation of air inside and outside the flocking glue, makes the flocking more plump, beautiful and has good fastness.

Description

technical field [0001] The invention relates to an adhesive for flocking, in particular to an acrylic acid and its ester flocking glue, a preparation method and a flocking process. Background technique [0002] Electrostatic flocking, the principle is that after the fluff is electro-chemically treated, under the action of the electric field generated by the high-voltage electrostatic generator, the original disordered state is changed, and the adhesive in the wet state is evenly and regularly implanted in a certain direction. Among them, fluff is formed on the surface of the adhesive after curing. The flocked product has a rich suede surface, soft hand feeling, bright color and unique style, which is favored by consumers. [0003] The adhesives used for flocking are divided into self-crosslinking adhesives and external linking adhesives. Self-crosslinking adhesives contain groups that make molecular chains self-crosslinked, such as methylol, Epoxy group, also has a methylol...
