▎ 摘　　要

NOVELTY - Graphene fire-retardant and flame-retardant sealant comprises a fire-retardant base material. The fireproof rubber base material includes room temperature vulcanized methyl silicone rubber, dimethyl silicone oil, flame-retardant heat-insulating agent A, and flame-retardant heat-insulating agent B. The flame-retardant heat-insulating agent A includes active nano-calcium and aluminum hydroxide. The flame-retardant heat-insulating agent B includes fumed silica, graphene and aerogel. USE - Graphene fire-retardant and flame-retardant sealant. ADVANTAGE - The graphene fire-retardant and flame-retardant sealant has good flame-retardant and heat-insulating properties, and has a long service life, good elongation and strong displacement resistance.
