High-gloss washing resistant environmental-friendly print paste and preparation method thereof

Abstract

The invention discloses high-gloss washing resistant environmental-friendly print paste and a preparation method thereof; the printing paste comprises water-based acrylic emulsion, modified water-based polyurethane emulsion, ammonia, defoaming agent, preservative, water-based wax emulsion, wetting and leveling agent, dispersing agent, toner, moisturizing agent and thickener. The preparation method comprises the steps that: A. stirring and filtration: the water-based acrylic emulsion and the water-based polyurethane emulsion are added into a dispersion cylinder by the formula ratio, and are stirred while being sequentially added with the ammonia, the defoaming agent, the preservative, the water-based wax emulsion, the moisturizing agent, the wetting and leveling agent and the dispersing agent; after the materials are added in, the mixture is stirred for 10min to 20min until being uniform fully; the mixture is filtered by a 200-mesh filter mesh bag; B. dispersion and grinding: the toneris added into the liquid mixture, stirred and dispersed for 30min to 50min; the thickener is added in, stirred and dispersed for 10min to 20min; and then the liquid mixture is ground on a three-roll grinder; and C. detection and packaging: the product is sampled to detect the pH value, the viscosity and the fineness, and the product is packaged after all the indexes are qualified.

Description

technical field [0001] The invention relates to a high-gloss washable and environment-friendly printing glue, and also relates to a preparation method of the printing glue. Background technique [0002] Aiming at the disadvantages of traditional dyeing process, such as complicated, polluting, high cost and long price cycle, pigment printing has emerged at home and abroad. The process of pigment printing is simple, saves energy, has no waste water discharge, complete color spectrum, convenient color matching and imitation, and clear printing outline. The authenticity rate is high, the reproducibility is strong, and the general light fastness is good. my country only began to import acrylic adhesives for pigment printing in the 1960s, and then began research work in this area. In recent years, many new materials can be used in the pigment printing process, especially with the development of synthetic fibers and their blended fabrics, the superiority and importance of pigment ...

Problems solved by technology

[0003] In the production of textile printing glue, it is generally divided into white glue and transparent glue. When white glue is printed on textiles, it will be a white pattern; The manufacturer's printing pattern requires adding different color pigments to print a coating of different color patterns; therefore, the quality of the printing white glue and transparent glue is directly related to the quality of the printing coating, especially the quality of the white glue, because of its film formation The material content is less and the powder is more, so the requirements for washing fastness and gloss are higher; at present, acrylic emulsion is generally used as the main raw material for pigment printing at home and abroad, and its disadvantages are: the rubbing fastness and rubbing fastness are not good enough, and the gloss Poor strength, high temperature sticking back and other shortcomings

Pigment printing with water-based polyurethane emulsion as the main raw material has good firmness and significantly improved gloss, but the coating has poor elasticity and is expensive; this is closely related to the structure, shape and post-crosslinking degree of the adhesive.
