The invention belongs to the field of auxiliary agents for building materials, and a graphene oxide modified slump-preserving mother liquor comprises the following components in parts by weight: 20-60 parts of graphene oxide dispersion liquid, 300-360 parts of isopentenol polyoxyethylene ether, 2.5-3 parts hydrogen peroxide, 38-40 parts acrylic acid, 50-55 parts hydroxyethyl acrylate, 1.2-1.5 parts ascorbic acid, 2-2.5 parts mercaptopropionic acid, 25-35 parts sodium hydroxide. The graphene oxide-modified slump-preserving mother liquor introduces graphene oxide, which improves the slump-preserving performance of the slump-preserving mother liquor on the premise that the sensitivity of the slump-preserving mother liquor does not increase. At the same time, the present invention also proposes a preparation method and a use method of a graphene oxide modified slump-preserving mother liquor. |
