Problems solved by technology

At this stage, the polymerization method of acrylate mainly adopts the emulsion polymerization method, which is difficult to ensure that the silicone modified monomer is copolymerized to the polyacrylate macromolecule
In addition, the polyacrylate latex produced has a large particle size difference and poor particle size dispersion, which easily leads to emulsion breakage and poor stability and storage resistance.

Abstract

The invention discloses a high dye-carrying adhesive for water-free printing of disperse dyes and a preparation method thereof, which comprises the following components and the mass ratio of each component is: water: 70g, emulsifier: 1-3g, acrylic acid Ester monomer: 20-45g, acrylic acid: 0.5-2g, organosilicon monomer: 0.3-3.5g, co-emulsifier: 0.2-2.5g, initiator: 0.1-0.6g. Good reproducibility, low requirements for processing equipment, simple method, which is conducive to industrial production, silicone modified acrylate adhesive has a low solubility parameter, which is quite different from the solubility parameter of disperse dyes, and can significantly reduce the dye and printing size film. Compatibility, promotes the directional transfer of dyes from the size film to the fabric surface, reduces the content of free dyes in the size film, thereby improving the surface color yield and rubbing fastness of printed fabrics; on the other hand, the silicone segment is soft, which can effectively improve Printed fabric feel. Therefore, the high dye-carrying non-washing printing adhesive has broad application prospects in printing production.

Description

【Technical field】 [0001] The invention belongs to the field of adhesives, and in particular relates to a preparation method of an organosilicon modified acrylate adhesive with high dye-carrying property and its application as a printing adhesive in the water-free printing of polyester disperse dyes. 【Background technique】 [0002] Traditional polyester disperse dye printing requires soaping and multiple washing processes to remove unfixed dyes, printing pastes and chemicals. In order to achieve high efficiency, energy saving and zero discharge of washing wastewater, disperse dyes wash-free printing technology came into being. This technology uses disperse dyes to replace pigments in pigment printing pastes, utilizes the film-forming properties of polymer binders and the properties of disperse dyes in solid-phase dyeing (hot-melt dyeing), based on the migration, diffusion and For the fixing principle of polyester fiber, a short process (printing-drying-baking) similar to pig...
