▎ 摘  要

NOVELTY - A cement-based material surface wave absorbing agent comprises graphene oxide and M-iron oxide nano-composite material, where M is iron, cobalt, manganese or nickel. USE - Cement-based material surface wave absorbing agent. ADVANTAGE - The method is simple, convenient, easy to operate and suitable for large-scale production, and has high yield. The cement-based material has dense surface and improved mechanical strength. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation of absorbing agent comprising dissolving iron salt and ferrous salt, cobalt salt, manganese salt or nickel salt in water, adjusting pH to 8-11, reacting at 10-150 degrees c, and ultrasonically or mechanically stirring to obtain nano-composite material; adding graphene oxide, and ultrasonically or mechanically stirring to obtain crude product; and magnetically separating, drying at room temperature, and dispersing; and (2) application of absorbing agent comprising spraying, brushing or soaking cement-based material surface with absorbing agent under the action of external magnetic field, and dipping or brushing a layer of siliceous material.
