Digital printing adhesive and preparation method thereof

Abstract

The invention relates to a digital printing adhesive. The digital printing adhesive is prepared from the following raw materials in parts by weight: 30-35 parts of bisphenol A epoxy acrylate, 2-3 parts of sodium dodecyl benzene sulfonate, 5-6 parts of glycerinum, 6-8 parts of trimethylolethane, 3-4 parts of xylitol, 10-12 parts of tris(2-butoxyethyl) phosphate, 5-8 parts of butyl methacrylate, 14-16 parts of 1,6 hexanediol diacrylate, 10-15 parts of trimethylolpropane triacrylate, 2-3 parts of nonyl phenol, 3-4 parts of polyvinyl butyral, 1-2 parts of ammonium persulfate, 4-5 parts of addition agent, and 70-80 parts of water. The digital printing adhesive does not contain APEO (alkylphenol ethoxylates), formaldehyde, degradable compounds and the like, is environment-friendly and pollution-free, has good stability and dispersing property, can prevent pigment particles from coagulation, can be baked to form a film through crosslinking at lower temperature, greatly reduces the energy consumption and sewage discharge, and has the characteristics of strong adhesive force, high curing speed, good toughness, and good waterproof, hot water resistant and drug resistant properties.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing auxiliaries, in particular to a digital 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 directly affects t...
