description The utility model discloses a homodromous meshed extrusion screw for producing a halogen-free flame retardant thermoplastic elastomer. The homodromous meshed extrusion screw comprises a charging and solid conveying section, a fusion section, a mixing section, an exhaust section and an extrusion section connected in sequence from one end of the screw to the other end of the screw, wherein the fusion section comprises a three-head meshing element. According to the homodromous meshed extrusion screw, under the same rotation speed of the screw, high shearing force can be applied to materials, and the material layer becomes thinner, the heat transfer performance is good, and the screw is more beneficial to material fusion plasticization.
