▎ 摘  要

NOVELTY - Graphene suspension comprises 0.5-2.5 pts. wt. polycarboxylic acid water reducing agent, 0.01-0.05 pts. wt. graphene, 0.008-0.04 pts. wt. graphene oxide and 170-200 pts. wt. water. The molar ratio of acid ether of the polycarboxylic acid water reducing agent is (2-6):1. USE - Graphene suspension for cement-based material (claimed). ADVANTAGE - The graphene suspension has high dispersibility and good compatibility with cement, and effectively improves the mechanical properties, durability, electrical conductivity and smart performance of cement-based materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene suspension, which involves: (A) weighing polycarboxylic acid water reducing agent, graphene, graphene oxide and water, adding graphene oxide to water to obtain a graphene oxide solution; and (B) mixing graphene with the graphene oxide solution, and adding the remaining amount of water, and performing ultrasonic treatment, adding the polycarboxylic acid water reducing agent, and performing ultrasonicated again to obtain the graphene suspension.
