Abstract:
     The invention relates to a modified polyvinyl chloside resin complex material,using coal dust instead of CaCO3 as filler for PVC resin. Three kinds of titanate can be used as coupling agent to treat PVC-coal dust system. As the hard PVC material producted by PVC-coal dust compared with that producted by PVC-CaCO3 system,both have the similar mechanical properties but the former possesses far better anticossosion property than the latter.
