▎ 摘  要

NOVELTY - Light cover coating material for preventing polonium-210 pollution on walls and ceiling surfaces in nuclear facilities comprises main agent comprising water-based epoxy resin, curing agent comprising water-based organic amines, functional additives and auxiliary agents contained in the main agent and/or curing agent, when used in nuclear facilities, the main agent and curing agent are mixed in a molar ratio of amine functional group/-COC=0.7-0.9. USE - The light cover coating material is used for preventing polonium-210 pollution on walls and ceiling surfaces of nuclear facility structures (claimed) and used in any environment with high requirements for radiation protection and/or penetration resistance. ADVANTAGE - The light cover coating material meet the protection requirements required by the environment in which it is used. The light cover coating material has safe and environment-friendly water-based performance, which is different from the solvent-based high-solid epoxy coating and inorganic zinc-rich coating used currently.
