NOVELTY - The utility model claims a flame-retardant graphene composite plate, belonging to the technical field of flame retardant material, comprising an upper plastic plate and a lower plastic plate; the upper plastic plate is provided with an upper graphene plate; the lower plastic plate is provided with a lower graphene plate; two sides of the upper graphene plate and the lower graphene plate are provided with a side graphene plate; an insulating cavity is formed between the upper plastic plate and the lower plastic plate and the two side graphene plates; the inner part of the heat insulating cavity is provided with a row of rubber column, rubber column is divided into a first rubber column and a second rubber column; the upper and lower end faces of the first rubber column are just supported on the inner end faces of the upper plastic plate and the lower plastic plate; the upper and lower ends of the second rubber column extend into the upper plastic plate and the lower plastic plate. The utility model has higher strength, four sides are provided with a graphene plate; the middle cavity exists; the flame-retardant heat insulation effect is better; the anti-pressure and anti-vibration ability is stronger.
