| 摘 要： | 聚脲聚氨酯环氧涂料用於混凝土钢筋防腐蚀的研究林薇薇（浙江大学高分子系杭州３１００２７）钢筋混凝土建筑物耐久性下降的主要原因之一是增强钢筋的腐蚀。因为混凝土是多孔性凝胶体，空气中的氧、湿气和其它腐蚀介质能通过孔隙和细裂缝侵蚀钢筋，而钢筋变成铁锈时体积要...

| Abstract: | In order to improve corrosion prevention performance of epoxy coating,a new polyurea/polyurethane(ATPU)-modified epoxy coating was synthesized.The changes of bonding strength to steel plate were examined after immersion in corrosives such as water,alkali,salt and organic solvents etc.Results showed that this modified epoxy coating possessed excellent bonding strength and chemical resistance.Accderated electrocheimcal measurements of the modified epoxy coated steel bar embedded in concrete also proved that the ATPUepoxy coating was significantly superior to the conventional polyamide epoxy coating in corrosion prevention. |
