Preparation method of special coating ink inkjet printing adhesive

Abstract

The present invention discloses a preparation method of a special coating ink inkjet printing adhesive, the method is as follows: adding 0.5-2 wt % of a fatty acid polyoxyethylene ether sulfate sodiumand tridecyl polyoxyethylene ether mixed emulsifier into 20-25 wt % of distilled water, stirring evenly, adding 28-33 wt % of butyl acrylate, 2-5% of styrene and 2-5% of acrylonitrile, using an emulsifying machine for emulsifying at 1000r / min for 15-20mins, taking 5-8% of a pre-emulsified monomer out, adding 0.5-1% of IBMA, using the emulsifying machine for emulsifying at 1000r / min for 5mins,dissolving 0.1-0.15% of ammonium persulfate in 3-4% of water, adding 25-35% of distilled water and 0.2-0.5% of itaconic acid into a flask, first adding 5% of the pre-emulsified monomer and 10% of anammonium persulfate solution, stirring, dropwise adding the remaining pre-emulsified monomers and ammonium persulfate, thermally insulating for reaction for 1-1.5h, adjusting emulsion pH to 6.5-7.5 with ammonium hydroxide, filtering and discharging. The special coating ink inkjet printing adhesive has no formaldehyde release. When applied to coating ink ink-jet printing process, the special coating ink inkjet printing adhesive can improve the printing color fastness and obtain soft hand feeling. The special coating ink inkjet printing adhesive product has a small particle size, can pass through EPSON, star and other nozzles, and has no nozzle blocking problem.

Description

technical field [0001] The invention relates to the technical field of an environmentally friendly fine-grained acrylic resin special adhesive for paint and ink for inkjet printing of fabrics, in particular to a preparation method of an inkjet printing special adhesive for paint and ink. Background technique [0002] With the improvement of the overall level of the world economy, people's demand for clothing and textiles is becoming more and more individualized and diversified, which requires the traditional textile industry to change to the direction of multi-variety and small-batch production. Textile digital inkjet printing technology is characterized by high-quality and short-process printing, and the production response process is short and fast, which can well meet the requirements of immediate delivery. At present, the research and development of digital inkjet printing technology mainly focuses on printing machines, inks and processes. Inkjet printing ink can be div...
