NOVELTY - The utility model model claims an anti-stretch flame-retardant combined V-belt, relating to the technical field of transmission. In the present utility model, side V strip, the middle V strip is orderly provided with a bottom glue layer from bottom to top, a tensile layer and a top rubber layer, one side of the tensile layer of the side V strip is provided with an inner inclined area, the two sides of the tensile layer of the middle V strip are provided with an inner inclined area, the inner inclined area is located below the tensile layer, the inner inclined area of the tensile layer and the tensile layer are provided with several rope cores; between the side V strip and the middle V strip and the adjacent middle V strip are formed with a waste heat, the lower side surface of the V belt layer is provided with a graphene layer facing waste heat the gap. The utility model model enhances the shape of the side position of the inner surrounding area of the connecting group V belt, and configures the graphene layer to quickly share the heat generated by wrapping cloth at two sides of the middle V contact of the wheel groove and the heat generated by the inner side of the V belt at the side.
