摘　　要：己二异氰酸酯(HDI)分子具有特殊的直链饱和结构和含有高度不饱和双键的异氰酸酯基团,化学性质非常活泼,能够与水生成聚二脲,与多元醇反应生成聚胺酯,与胺反应生成缩二脲。在催化剂作用下能生成二聚体和三聚体。HDI及其二聚体和三聚体具有不变黄性,广泛应用于涂料、胶粘剂、皮革等领域。本文主要介绍HDI的主要化学反应的进展。With active chemical properties, HDI bears special direct chain saturation structure and high monounsaturated double bond isocyanate group, we can get Polyurea if combine it with water, and polyurethane if with Polyol, biuret if with amine. With certain additives, it could generate dimer and trimer which was stable enough to stop them from yellow changing and widely used in coatings, adhesives, and synthetic leather industry. This article will give you perfect clues on the development of chemical process of HDI.
