Abstract

The invention relates to the technical field of production of polyurethane, and particularly discloses bright waterborne polyurethane. The bright waterborne polyurethane comprises a component A and acomponent B, wherein the component A comprises the following components in parts by weight: 70-80 parts of polycarbonate diol, 10-20 parts of polyoxypropylene triol, 30-40 parts of isophorone diisocyanate, 5-10 parts of dimethylolpropionic acid, 5-10 parts of 1,2-propanediol, 0.2-0.8 part of a catalyst, 5-10 parts of triethylamine and 200-250 parts of deionized water; and the component B comprisesthe following components in parts by weight: 70-80 parts of polycarbonate diol, 10-20 parts of polyoxypropylene triol, 20-30 parts of isophorone diisocyanate, 5-10 parts of dimethylolpropionic acid,0.2-0.8 part of a catalyst, 0.3-0.7 part of ethylenediamine, 5-10 parts of triethylamine and 180-200 parts of deionized water. According to the bright waterborne polyurethane, the defects of the priorart are overcome, use of toxic organic solvents is reduced, the situation that the toxic organic solvents volatilize to cause environmental pollution is avoided, and meanwhile, the finished product polyurethane is high in glossiness after forming a film, feels soft, and is good in color fastness to water.

Description

technical field [0001] The invention relates to the technical field of polyurethane preparation, in particular to a bright water-based polyurethane and a preparation method thereof. Background technique [0002] Bright resin is a kind of resin commonly used in the production of fabric printing adhesives, which can give the printed surface a bright appearance, and can also give the synthetic a certain feel. Most of the existing bright resins are solvent-based polyurethane resins, which are prepared by adding various additives after dilution with solvents. [0003] The existing solvent-based polyurethane resin needs to be diluted with an organic solvent. During use, it will cause environmental pollution due to solvent volatilization, which does not meet environmental protection requirements and physical and mental health. Therefore, in recent years, people have focused on the development of water-based polyurethane bright resin. Contents of the invention [0004] The purpos...
