水乳型聚氨酯环氧硅氧烷常温交联(Ⅰ) 交联机理及交联涂层物化性能

Epoxy Silane as Ambient Temperature Cross-linking Agent for Aqueous Polyurethane(I) Cross-linking Reaction Mechanism and Film Properties

本文报导了水乳型聚氨酯与环氧硅氧烷常温交联剂的交联机理及涂层交联后物化性能的变化，为环氧硅氧烷在皮革涂饰中的应用提供了理论依据。

The cross-linking reaction mechanism and film properties of aq. polyurethane using epoxy silane as ambient temperature cross-linking agent were reported. we found that aq. polyurethane with post-added epoxy silane provide curable coatings, in which properties such as water-resistance ,solvent-resistance are dramatically improved.
