Abstract

The invention discloses a preparation method for an organic silicon-modified printing adhesive. The preparation method comprises the following steps of: preparing an organic silicon pre-emulsion: adding 80-140 parts by weight of deionized water, 3-7 parts by weight of a compounding emulsifier, 8-12 parts by weight of an organic silicon monomer and 0.1-0.2 part by weight of a silane coupling agentinto a reaction kettle, stirring at the room temperature for 40-70 minutes, heating to 75-90 DEG C, and reacting at the temperature for 110-130 minutes to obtain the organic silicon pre-emulsion; andpreparing a printing adhesive: controlling the temperature of the organic silicon pre-emulsion at 75-85 DEG C, dropwise adding an acrylate monomer and an initiator in sequence while stirring at the high speed of 1,000 revolutions per minute within 2 hours, heating to 4-6 DEG C, preserving heat for reacting for 25-35 minutes, cooling, and adjusting the pH to 6-7 with sodium hydroxide to obtain theorganic silicon-modified printing adhesive. The preparation method has the advantages of simple process steps, high storage stability, washability, superior softness and contribution to environmentalfriendliness.

Description

technical field [0001] The invention belongs to the technical field of preparation of textile printing and dyeing auxiliaries, and in particular relates to a preparation method of an organic silicon modified printing adhesive. Background technique [0002] Pigment printing achieves the purpose of coloring by means of adhesives to adhere pigment particles to the fabric, so it is not picky about various fibers. Moreover, pigment printing has a simple process, a wide range of colors, easy color matching, and no need for washing after color fixing, so it has the characteristics of water saving and energy saving. In the global printed fabrics or fabrics, the share of pigment printing is increasing year by year. Adhesive is the main component of pigment printing paste, and its quality directly affects the quality of the final product. At present, the adhesives for pigment printing are mainly acrylic esters such as Chinese patents (CN101948555A, CN102190989A, CN101942772A), which ...
