COATING SEALING COAT COMPOSITION

摘要

The present invention relates to a composite anti-corrosion inner lining containing a water-borne epoxy coating sealing coat and an application thereof. The composite anti-corrosion inner lining comprises a cement mortar inner lining layer and the water-borne epoxy coating sealing coat coated on the cement mortar inner lining layer. The composite anti-corrosion inner lining has the advantages of preventing the precipitation of alkaline substances and harmful components from the cement mortar; the water in the cement mortar can be sealed by the water-borne epoxy coating sealing coat so as to prevent the generation of cracks; the composite anti-corrosion inner lining simultaneously poses the active anti-corrosion function of a cement mortar inner lining and passive anti-corrosion function of an organic coating; the roughness coefficient of the cement mortar inner lining can be reduced, and the composite anti-corrosion inner lining can withstand the water pressure changes in the water conveying process without being damaged.
