The organic montmorillonite is developed by the modification with the suitable organ-layer, with montmorillonite as the main raw material. The melting PVC is intercalated into the organic montmorillonite by use of the affinity of PVC. The montmorillonite layer is exfoliated and dispersed in PVC phase in nanosize. The PVC-U/montmorillonite nanocomposite pipe is developed by the above technology. The property of the pipe meets the requirement of the national standard. The montmorillonite structure is characterized by IR and the thermal performance of the composite is inspected by TCA.
