| 环氧树脂又称作人工树脂、人造树脂、树脂胶等。是一类重要的热固性塑料,广泛用于黏合剂,涂料等用途。环氧树脂是泛指分子中含有两个或两个以上环氧基团的有机高分子化合物,除个别外,它们的相对分子质量都不高。 Epoxy resin is also called artificial resin, artificial resin, resin glue and so on. It is a kind of important thermosetting plastics, widely used in adhesives, coatings and other applications. Epoxy resin is an organic macromolecule compound containing two or more epoxy groups in a general sense. Except for a few, their relative molecular weight is not high. 环氧树脂的分子结构是以分子链中含有活泼的环氧基团为其特征,环氧基团可以位于分子链的末端、中间或成环状结构。由于分子结构中含有活泼的环氧基团,使它们可与多种类型的固化剂发生交联反应而形成不溶、不熔的具有三向网状结构的高聚物 The molecular structure of epoxy resin is characterized by the active epoxy group in the molecular chain. The epoxy group can be located at the end, middle or ring structure of the molecular chain. Because of the active epoxy groups in the molecular structure, they can cross-link with various curing agents to form insoluble and immiscible polymers with three-way network structure. |
