▎ 摘　　要

NOVELTY - Preparation method of suspended vermiculite silicate fire extinguishing agent, involves (1) grinding the leech stone powder to prepare an aqueous dispersion; (2) adding hollow glass beads into the dispersion liquid and fully stirring; (3) adding the graphene oxide dispersion liquid into the dispersion liquid and fully stirring; (4) adding ammonium fluoride into the dispersion liquid stirred evenly and then is kept stand, and graphene oxide is reduced and is coated with vermiculite hydrate and hollow glass bead particles; and (5) cleaning particles and selecting a part which can be suspended in water, and adding a proper amount of water according to calculation to obtain the suspended water vermiculite fire extinguishing agent. USE - Preparation of suspended vermiculite silicate fire extinguishing agent. ADVANTAGE - The preparation reparation method of suspended vermiculite silicate fire extinguishing agent with silicate particles and hollow glass beads are coated in graphene together, so that density of vermiculite silicate particles is close to that of water, and the vermiculite silicate fire extinguishing agent is stably dispersed. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a suspended aqueous vermiculite fire extinguishing agent.
