Abstract

The invention discloses a waterproof flexible printing adhesive, which is prepared from the following raw materials in parts by weight: 35-40 parts of epoxy acrylate, 2-3 parts of sodium carboxymethyl cellulose, 5-7 parts of rosin, 1-2 parts of diethylenetriamine, 2-3 parts of sodium hydroxide, 8-10 parts of methyl diphenylene diisocyanate, 1-2 parts of sodium dodecyl benzene sulfonate, 6-8 parts of acrylonitrile, 20-30 parts of 1,6-hexanediol diacrylate, 1-2 parts of cellulose acetate butyrate, 1-2 parts of sodium hexametaphosphate, 5-8 parts of ethylene glycol, 1-2 parts of ammonium persulfate, 4-5 parts of assistant, and 60-65 parts of water. The adhesive disclosed by the invention has excellent waterproof effect, and also has the characteristics of good hot water resistance, drug resistance, flexibility and toughness. A coating employing the adhesive is simple in printing process, fast in curing speed, clear in outline, free of hot-melting and efficient open washing equipment, and free of acid and alkali treatment. No acid and alkali waste liquid is formed; energy consumption is correspondingly saved; pollution is reduced; the waterproof flexible printing adhesive has a broad prospect.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing auxiliaries, in particular to a water-repellent flexible printing adhesive and a preparation method thereof. Background technique [0002] The so-called pigment printing is to fix the pigment which is insoluble in water and has no affinity and reactivity to the fabric on the fabric through the action of the adhesive, so as to achieve the purpose of coloring. According to the latest information, about half of the printed fabrics produced in the world are pigment printed. Pigment printing binder is the main component of pigment printing paste, and the quality of pigment printing finished products is directly affected by the performance of printing binder. [0003] At present, the quality of printing adhesives is different, and the printing defective rate caused by adhesive quality problems is more than 3%, causing huge economic losses, and the quality of printing adhesives d...
