Problems solved by technology

[0011] The present invention is accomplished in view of the technical problems existing in the above-mentioned prior art, and its purpose is to provide a kind of water-dispersible polyurethane resin composition and its manufacture method, thus, can overcome the problem of using the existing polyurethane resin composition. The disadvantage of the fiber products obtained by the treatment of carbonate polyurethane resin is that the hand feel is too hard. Although it is a water-dispersed polyurethane resin obtained by using polycarbonate diol, it can The base material gives a soft feel and a sense of resilience, and has good dyeing resistance. The obtained fiber products will not be cracked or peeled off due to heat or rubbing, and the dyeing process can be fully dyed. Maintain a soft feel and a sense of resilience

Embodiment 1

[0116] In a 4-necked flask with a stirrer, a reflux cooling tube, a thermometer, and a nitrogen blowing tube, the following components were measured respectively, that is, as the above-mentioned polycarbonate diol derived from decanediol, the polycarbonate diol derived from decanediol with a number average molecular weight of 3000 was measured. Diol polycarbonate diol (manufactured by Mitsubishi Chemical Corporation, trade name "BENEBiOL") TM NL3010DB") 76.3 parts; as the above-mentioned polyol with a molecular weight of 400 or less having only hydroxyl groups, measure 0.9 parts of trimethylolpropane and 0.9 parts of 1,4-butanediol; as the above-mentioned polyether polyol, measure polyol Ethylene oxide polyoxypropylene random copolymer glycol (manufactured by ADEKA Corporation, trade name "ADEKAPOLYETHER PR-3007", number average molecular weight: 3000, oxyethylene group content: 70%) 3.0 parts; as a solvent, measure 32.8 parts of methyl ethyl ketone , then mix evenly, then ad...

Embodiment 2～14、 comparative example 1～5

[0136] The above-mentioned polycarbonate diol derived from decanediol, the above-mentioned polyol having a molecular weight of 400 or less having only hydroxyl groups, the above-mentioned polyether polyol, other polycarbonate diols, polyols having a molecular weight of 400 or less having other functional groups, The type and amount of solvent, organic polyisocyanate, catalyst, reaction inhibitor, emulsifier, water, and chain extender were changed to those shown in Table 1 to Table 4, except that, according to the same method as in Example 1, polyurethane was produced Ester resin composition, and further fabricate pre-dyed fiber products and dyed fiber products. In addition, in Comparative Example 5, 2.2 parts of triethylamine were used to neutralize 2,2'-dimethylolpropionic acid.

[0137] About the non-dyeing fiber products and dyed fiber products obtained in Examples and Comparative Examples, hand feeling (softness), rebound feeling, and dyeing resistance were measured.

Abstract

The present invention relates to a water-dispersed polycarbonate-based polyurethane resin composition, which is obtained by chain-extending a urethane prepolymer having an isocyanate group at the end with a polyamine compound, wherein , the above-mentioned polyamine compound has more than two amino groups selected from primary amino groups and secondary amino groups in one molecule, and the above-mentioned urethane prepolymer with isocyanate groups at the end is the reaction of polyalcohol and organic polyisocyanate The product, the above-mentioned polyalcohol, contains a polycarbonate diol having a structural unit derived from 1,10-decanediol and a polyol having a molecular weight of 400 or less having only a hydroxyl group as a functional group.

Description

technical field [0001] The present invention relates to a water-dispersed polycarbonate-based polyurethane resin composition, a fiber product treated using the same, and a method for producing the water-dispersed polycarbonate-based polyurethane resin composition. Background technique [0002] Water-dispersed polyurethane resin has the characteristics of low pollution, safety and easy handling when used as a water-solvent-type polymer processing agent, and has excellent durability, chemical resistance and abrasion resistance etc., so it is used in various fiber products as a high-functional aqueous dispersion. In addition, for water-dispersed polyurethane resins, by using polycarbonate-based polyols as polyalcohol components, excellent strength, light resistance, heat resistance, hydrolysis resistance, oil resistance, etc. can be imparted. properties, so it is expected that its importance will gradually increase in the future. [0003] However, for polyurethane resin obtai...
