Problems solved by technology

But this invention only uses acrylate room temperature self-polymerization as the main preparation method of printing adhesive, although the release of formaldehyde and the use of emulsifier containing APEO are limited, but its reaction characteristics make the printing adhesive prepared by it thermally sticky Cold and brittle, poor wear resistance

Abstract

The invention provides a polyurethane modified acrylate pigment printing adhesive for polyester oxford fabric and a preparation method thereof. The preparation method comprises the following steps: (1) preparing a waterborne polyurethane compound emulsifier from polyhydric alcohol, polytetrahydrofuran ether glycol, polycaprolactone polyhydric alcohol, hexamethylene diisocyanate, isophorone diisocyanate, 2,2-dimethylol propionic acid, hydroxyethyl methyl acrylate, triethylamine, deionized water and ethylene diamine; (2) preparing an organic silicon prepolymer from the waterborne polyurethane compound emulsifier, ionized water, an organic silicon monomer D4 and A-2120; (3) preparing a pre-emulsion from deionized water, butyl acrylate, acrylic acid, styrene, methyl acrylate, itaconic acid, an organosilicon prepolymer and a crosslinking monomer; and (4) preparing the polyurethane modified acrylate adhesive from the pre-emulsion, deionized water, APS, the remaining pre-emulsion, an APS aqueous solution and a sodium hydrogen sulfite aqueous solution. When the polyurethane modified acrylate adhesive is used for printing polyester fabrics, the polyester fabrics are high in fastness, bright in color, washable, soft in hand feeling and stain-resistant.

Description

technical field [0001] The invention relates to a polyurethane-modified acrylate pigment printing adhesive and a preparation method thereof, in particular to a pigment printing adhesive for 500D polyester Oxford. [0002] technical background [0003] Pigment printing is to use adhesives, paint pigments, organic additives and water to prepare a color paste. The color paste is transferred to the surface of the fabric through the printing process to form a flower pattern, which is fixed on the surface of the fabric after drying into a film. [0004] The advantages of pigment printing are that the process is short, the production is simple, the fabric does not need to be washed after drying, the production efficiency is high, energy is saved, and there is no waste water. Pigment printing has a complete color spectrum, bright color, clear printing outline, distinct layers, and good light fastness. The color paste can be mixed at will, the color matching is convenient, and there ...
