NOVELTY - The utility model claims a three-dimensional impression graphene PU tire manufacturing equipment, the polyurethane material is mixed in an amount of graphene by using two extruders plasticizing graphene PU composite material, divided into four times covering the carcass, the first layer of contact rim is graphene PU mixing material, after extruding the first layer, filling an amount of supercritical nitrogen, mixing and extruding foaming graphene PU with micro-bubbles by laminated machine, on the base of the first layer, adhering the second layer and third graphene layer by foaming PU material, four-layer uses graphene PU material; the upper pressing roll and the lower pressing roll compact each layer in the process of adhering four layers of materials, finally the hot press board with tire tread stamps tire tread on the carcass under the driving of the oil cylinder. This utility model has simple manufacturing equipment to prepare a graphene PU foaming tyre, by adding certain quantity graphene and supercritical nitrogen micro-bubbles in the polyurethane material, made of PU tyre with elasticity, thermal conductivity and more comfortable.
