▎ 摘　　要

NOVELTY - Composite elastomer material comprises 40-80 wt.% elastomer matrix, 0.1-10 wt.% flow modifier, 0.1-38 wt.% composite flame retardant, 0.1-5 wt.% graphene microplates, 0.1-5 wt.% intercalation bentonite, 0.1-5 wt.% nucleating agent, and 0.1-5 wt.% antioxidant. USE - Composite elastomer material. ADVANTAGE - The material has high flame retardant performance, high thermal stability, migration resistance, electrical conductive performance, and excellent physical performance, and reliably meets UL94V-0 with a sample thickness of 1.6 mm, and the heat distortion temperature can reach 90℃, and the hardness can reach 85. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the composite elastomer material, involving (a) weighing the flow modifier, composite flame retardant, graphene microplates, intercalated bentonite, nucleating agent, and antioxidant, mixing, adding the elastomer matrix, and continuously mixing to obtain a mixture and (b) adding the mixture to a twin-screw extruder, melt-kneading, and extruding to obtain the target product.
