Abstract

The invention discloses a preparation method of a flocking adhesive for spinning, which comprises the following steps: S1, in a reaction kettle, adding hyperbranched waterborne polyurethane acrylate, O-(ethylene oxybutyl)-N-(triethoxy silylpropyl)urea, acrylic acid-L-menthyl acrylate, polynorbornene-2, 3-dicarboxylic acid polytetrahydrofuran glycol ester, acrylic acid-2, 3-epoxypropyl ester modified 1-amino benzotriazole, crylic acid hexahydro-4, 7-methylene-1H- indenyl acrylate, an emulsifier and ethanol into part of water, and stirring until the components are uniformly mixed; and S2, adding the rest water into the mixture prepared in the step S1, slowly adding the mixture into the reaction kettle under the protection of nitrogen or inert gas at the temperature of 60-70 DEG C, slowly adding an initiator, and carrying out a constant-temperature reaction for 4-6 hours to obtain the flocking adhesive for spinning. The prepared flocking adhesive for spinning is good in wear resistance, moisture resistance, water resistance, solvent resistance and heat resistance, good in flocking effect, excellent in performance stability and high in peel strength.

Description

technical field [0001] The invention relates to the technical field of textile auxiliaries, in particular to a flocking glue for textile and a preparation method thereof. Background technique [0002] With the progress and development of society, environmentally friendly and fashionable textile fabrics are becoming more and more popular. Flocking fabrics are used in more and more fields because of their flexible patterns and brilliant colors. They are mainly used in clothing, shoes materials, automotive interior and decorative fabrics, etc. Most of the flocking fabrics in the prior art are prepared by 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 fluff is uniform and organic in a certain direction. Regularly implanted into the flocking glue in a wet state, and form fluff on the surface ...
