Problems solved by technology

[0005] ②In terms of adhesion, it can only be used for some materials, and it is completely unacceptable for some low-polar materials
[0006] ③ In terms of printing adaptability, screen printing is still used. Since the water-based polyurethane resin in the ink is a resin with a solid content of 30-35%, the ink configured has a low solid content, poor three-dimensional effect of the ink layer, and low printing efficiency.
[0007] ④ The water resistance and hydrolysis resistance of the ink layer are still not good

Embodiment Construction

[0041] The present invention will be further described below in conjunction with embodiment.

[0042] A kind of waterborne polyurethane resin that shoe material printing ink is used, the parts by weight of its formula:

[0043]

[0044]

[0045] The mixed diol is uniformly prepared by mixing adipic acid polyester diol, polycarbonate diol and dimer polyester diol, and the ratio of parts by weight is:

[0046] Diacid polyester diol 5 Polycarbonate diol 2

[0047] Dimer polyester diol 3.

[0048] A kind of manufacture method of the waterborne polyurethane resin that ink of shoe material is used, according to following method step: take raw material in proportion;

[0049] (1) Add mixed dibasic alcohol, isophorone diisocyanate, hexamethylene diisocyanate, urge organic bismuth catalyst, methyl ethyl ketone in the reaction kettle that agitator is housed, thermometer, condenser, heat up slowly 80- 90°C, reaction time 2 hours;

[0050] (2) Add dimethylolpropionic acid dissolve...

Abstract

Provided is waterborne polyurethane resin for shoe material ink. A formula comprises mixed dihydric alcohol, hexamethylene diisocyanate, isophorone diisocyanate, dimethylolpropionic acid, N-methyl-pyrrolidone, triethylamine, N-(2-amino ethyl) amino ethanesulfonic acid, amino ethyl group aminopropyl triethoxy silane, butanone, isophorone diamine, acetone, organic bismuth catalytic agent and deionized water. The waterborne polyurethane resin is high in abundance ratio, good in luminance and good in color fixing performance on pigment. 5% of waterborne isocyanate curing agent is added in prepared ink, xerotripsis resistance after drying for 48 hours is more than 450 times, wet rubbing resistance is more than 300 times, 90-degree bending measurement at the normal temperature of 25 DEG C achieves 80000-100000 times, and adhesion measurement of low polarity materials and polarity materials is good.

Description

technical field [0001] The invention relates to the technical field of water-based polyurethane ink resin, in particular to the resin used for water-based polyurethane ink for shoe materials. Background technique [0002] A recent report by the environmental protection organization Greenpeace stated that the waste water discharged into the Yangtze River and the Pearl River by the OEM factories of famous international sports brands such as NIKE and PUMA contains a variety of toxic substances; of course, this incident refers to clothing. In fact, many years ago, NIKE, ADIDAS, and PUMA promised the World Environmental Protection Organization to require their foundries to actively use water-based inks and water-based adhesives in shoe materials and clothing. After several years of promotion and application, it has also positively affected some domestic first-line sports brands. Such as Li Ning, Anta, etc. are also using water-based inks and adhesives. [0003] In recent years,...
