There have been many reports at home and abroad on the research on the synthesis of polydicyclopentadiene engineering plastics catalyzed by tungsten hexachloride. Polydicyclopentadiene is an engineering plastic with outstanding performance. However, under different industrial and mining conditions, it is necessary to synthesize composite materials with montmorillonite to realize the performance of composite materials. The latest research shows that polydicyclopentadiene/montmorillonite nanocomposites were prepared by the coordination reaction of triphenylphosphine and its oxides with tungsten hexachloride and its oxides. The structure and properties of polymer nanocomposites were characterized and tested by diffractometer and universal material testing machine.
The infrared test results show that triphenylphosphine and its oxides and coordination catalysts have some common characteristic peaks. At the same time, it is also observed that in the complexes with tungsten atoms as the core The strong absorption peak of the coordination bond between them shows that the scheme of synthesizing the coordination catalyst by triphenylphosphine and its oxide and tungsten hexachloride through coordination reaction is feasible. The preparation process of the new catalyst is simple and the price is low. Compared with the traditional catalyst, it is more stable under ordinary conditions and has stronger tolerance to air and water vapor. Through the activity test, it is found that the new catalyst has higher catalytic activity .
The synthesized catalyst was supported on montmorillonite (MMT) to form a supported catalyst, and the above-mentioned supported catalyst was used to catalyze the polymerization reaction of DCPD. XRD characterization shows that the degree of MMT exfoliation in the composite material is high, which proves that the polydicyclopentadiene/montmorillonite nanocomposite polymer material has been successfully prepared. Relevant mechanical performance test results show that this nanocomposite has high tensile and bending strength, and has tough and strong characteristics, especially when the MMT content reaches a certain level, the highest impact strength of the composite is 524.2J/m, The maximum hardness is 73D, which proves that the above catalytic system can prepare nanocomposites with excellent properties.
