In the formula of polyvinyl chloride composite material, the invented method replaces the conventional monoalkoxy type titanate coupling agent by (RCOO)aM(OX)b (where R is hydrocarbyl, M is metal element, and X is phosphoryl or sulfonyl). The said coupling agent has a good compatibility and rheological behaviour between the feed stock. This coupling agent has no special requirements for the kind and the moisture content of inorganic filling agent, and its cost is low. After the composite material is formed, its tensile strength and extensibility are not less than that of the composite material in which the ND-102 coupling agent is used. |
