TX系列含硫芳香族二胺扩链剂的应用研究进展

Application research progress of TX series of sulfur-containing aromatic diamine chain extenders

介绍了TX系列含硫芳香族二胺扩链剂的结构、性质及国内生产情况,重点介绍了TX系列含硫芳香族二胺扩链剂在合成聚氨酯(脲)弹性体中的应用研究进展。指出用以TX–2(2,4–二氨基–3,5–二甲硫基氯苯)为主要代表的TX系列含硫芳香族二胺扩链剂制备的涂料、胶黏剂、密封剂和弹性体制品的性能可与用E–300扩链剂制备的制品的性能相当,但TX–2更具成本优势。

The structure,properties and domestic production situation of TX series of sulfur-containing aromatic diamine chain extenders are introduced.The application research progress of TX series of sulfur-containing aromatic diamine chain extenders in the synthesis of polyurethane (urea) elastomers is emphatically introduced.It is pointed out that the performance of coatings,adhesives,sealants and elastomer products prepared with TX-2 (2,4-diamino-3,5-dimethylthio chlorobenzene),as the main representative of the TX series of sulfur-containing aromatic diamine chain extenders,can be comparable to that of products prepared with E-300 chain extender,but TX-2 is more cost-effective.
