Abstract

The invention specifically relates to a preparation method for a modified organosilicon fabric coating agent, belonging to the technical field of textile chemicals. The preparation method comprises the following steps: subjecting allyl glycidyl ether and silicone oil containing hydrogen at its terminal to a heating reaction and then carrying out modification with triethanolamine so as to synthesize quaternary ammonium salt-modified polyether organosilicon oil; then subjecting the modified organosilicon oil, butyl acrylate and ethylene glycol dimethacrylate to polymerization to produce an acrylate emulsion so as to obtain self-adhesive organosilicon oil; and subjecting the self-adhesive organosilicon oil, glass microspheres, water and other substances to shearing and dispersion. The modified organosilicon fabric coating agent prepared in the invention has high adhesion on a fabric, high color fastness and good water resistance and meets the development demands of finishing of fabric coatings.

Description

technical field [0001] The invention belongs to the technical field of textile chemical industry, and in particular relates to a preparation method of a modified organosilicon fabric coating agent. Background technique [0002] In recent years, the development of functional textiles has been extremely rapid, mainly in climate adaptation functions (such as temperature maintenance, waterproof and moisture-permeable, windproof and water-repellent, etc.), protective functions (flame retardant, antistatic, heat insulation, radiation protection, etc.), hygienic Health care and medical functions (such as antibacterial, antifouling, health care and skin care, etc.) and sports and leisure functions (such as softness, elasticity, moisture absorption and heat dissipation, etc.), and fabric coating finishing is a newly developed processing technology in textile finishing. It is mainly to uniformly coat a layer of polymer compound that can form a film on the surface of the fabric. Becaus...
