A COMPOSITE ANTI-CORROSION LINING COMPRISING WATERBORNE EPOXY COVER LAYER AND USE THEREOF

摘要

Disclosed is a composite anti-corrosion lining comprising waterborne epoxy painting cover layer. Said composite anti-corrosion lining is composed of a cement mortar lining layer and a waterborne epoxy painting cover layer coated on the cement mortar lining layer. A method for manufacturing the composite anti-corrosion lining and a cast iron pipe and a cast iron pipe assembly having the composite anti-corrosion lining are provided. The composite anti-corrosion lining can inhibit precipitation of alkali substance and harmful components in the cement mortar; the waterborne epoxy paint can seal water in the cement mortar to prevent crack from producing; the composite anti-corrosion lining has both the active anti-corrosion performance of the cement mortar lining and the passive anti-corrosion performance of an organic coating, and can reduce roughness coefficient of the cement mortar lining; and the composite anti-corrosion lining can undergo the change of water pressure during water delivery, so that the anti-corrosion lining is prevented from being damaged. The composite anti-corrosion lining is used in a cast iron pipe.
