Abstract

The invention belongs to the technical field of polyurethane, and particularly relates to a modified water-soluble high-elasticity polyurethane printing coating material as well as a preparation method and application thereof. The modified water-soluble high-elasticity polyurethane printing coating material is prepared from the following raw materials of acetone, polytetrahydrofuran, tetrabutyl titanate, isophorone diisocyanate, dimethylolpropionic acid, triethylamine, ethylenediamine, a biodegradable additive and deionized water, wherein the biodegradable additive is at least one of natural cellulose, artificially synthesized polycaprolactone, polyvinyl alcohol, an aromatic-aliphatic ester polymer, maleic anhydride modified polylactic acid (MPLA), butanediamine modified polylactic acid (BMPLA), monosaccharide and hexaldehyde saccharide. The printing coating material disclosed by the invention is high in biodegradation rate, good in elasticity, wear-resistant and washable. The preparation method disclosed by the invention is simple, easy to control and suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of polyurethane, and in particular relates to a modified water-soluble high-elastic polyurethane printing coating material and a preparation method thereof. Background technique [0002] On some elastic substances, coating materials such as printing, printing and coating various graphics and patterns require water-soluble high elasticity. The elastomer has excellent elastic properties, hydrophobic properties, stain resistance and fast curing properties. Polymer Materials. Such as textile high-elastic fabrics, their own fabrics, when the elongation of the fabric is about 200%, the elastic recovery rate remains 100%, and the printing, printing and coating materials on this type of fabric should have greater elasticity than high-elastic textiles. fabric. For this, highly elastic coating materials are required. Among them, after the water-soluble polyurethane is modified, it has this performance requirement a...
