架橋剤とその製造方法

Crosslinking agent and method for producing the same

Abstract

【課題】水媒体中で安定な会合体を形成し、室温ならびに高温での分散安定性、保存安定性に優れ、さらに低温での硬化性、主剤との相溶性にも優れた親水性ポリカルボジイミド化合物を含む架橋剤とその製造方法、ならびに架橋剤を含む水性樹脂組成物の提供。 【解決手段】一般式(1): 【化1】 (式中、平均重合度nは1〜15の整数を表し、R 1、 R 2 はイソシアネート基と反応し得る活性水素を分子中に1つ有する親水性有機化合物の残基からなる親水基であり、少なくともその一方がN-アルキルアミノスルホン酸塩が反応したものである。Xは、炭素原子数4〜20個の脂肪族炭化水素基、炭素原子数6〜15個の脂環式炭化水素基、又は炭素原子数7〜15個の芳香族炭化水素基である) で表される事を特徴とする親水性ポリカルボジイミド化合物を含む架橋剤。 【選択図】なし
PROBLEM TO BE SOLVED: To provide a crosslinking agent including a hydrophilic polycarbodiimide compound which forms a stable association in an aqueous medium, is excellent in dispersion stability and storage stability at room temperature and high temperature, and further is excellent in curability at low temperature and compatibility with a base agent, to provide a method for producing the crosslinking agent, and to provide an aqueous resin composition containing the crosslinking agent.SOLUTION: There is disclosed a crosslinking agent including a hydrophilic polycarbodiimide compound represented by general formula (1) (in the formula, an average polymerization degree n denotes an integer of 1 to 15; R, Rare hydrophilic groups comprising the residue of a hydrophilic organic compound having one active hydrogen in a molecule, which can react with an isocyanate group and at least one side of them is the hydrophilic group with which an N-alkyl amino sulfonic acid salt reacts; and X is a 4-20C aliphatic hydrocarbon group, a 6-15C alicyclic hydrocarbon group or a 7-15C aromatic hydrocarbon group).
