固化剂对有机改性凹凸棒石/聚苯胺环氧树脂复合涂层性能的影响
Influence of Curing Agent on Properties of Epoxy Resin Based Organic Attapulgite Clay/Polyaniline Coating
摘要
Abstract
The curing agent has very important effects on the anticorrosion and mechanical performance of coatings.The organic attapulgite clay/polyaniline (OAT/PAn) based coatings were prepared by in-situ oxidative polymerization with epoxy resin (ER) as bottom coat and OAT/PAn as additive.The coatings were cured by three kinds of curing agents including modified aliphatic amine 593, phenolic aldehyde amine T-31 and low molecular polyamide 650.The structures, anticorrosion, mechanical performance and water resistance of these coatings were discussed.The results showed that the composite coatings were completely cured by these three kinds of curing agents according to FTIR.The coating cured by 593 was more compact than others by SEM observations.The electrochemical test showed that the coating cured by 593 had a better corrosion protection performance, which corrosion potential and corrosion current density arrived to-318 mV and 1.193×10-6 A·cm-2, respectively.The adhesion strength of the coating after being cured by 593 was better than others, which reached 5B grade.Comparison with water-resistance for 168 h, the result indicated that the water hindrance capacity of the coating cured by 593 was stronger than other curing agents.关键词
