Abstract

The invention discloses a preparation method of the poly-dicyclopentadiene / montmorillonite nanocomposites. The support catalysts is prepared through the complex compound compounded by the compound with hydroxide radical and the tungsten hexachloride attaching to the organic montmorillonite, and the complex compound comprises the paratert-butyl phenol, quadruple ((Beta-(3, 5-tert-butyl -4- hydroxy phenyl) monoprop) pentaerythritol ester or 2-hydroxy-4-n-octyloxybenzophenone, etc. The polymerization of the dicyclopentadiene is catalysed through the in situ polymerization model by the catalyst, the interlayer spacing is increased when the dicyclopentadiene monomer polymerizing in the interlayer of the montmorillonite, the interlayer of the montmorillonite is peeled by the heat produced in the reaction, the peeled interlayer of the montmorillonite is scattered in the poly-dicyclopentadiene, and the poly-dicyclopentadiene / montmorillonite Nanocomposites is produced, and then a model is prepared by the reaction injection molding method. The composites are showed with nanocomposites structure through the X-ray diffractogram.

Description

technical field [0001] The invention relates to a polymer nanocomposite material, in particular to a preparation process of a polydicyclopentadiene / montmorillonite nanocomposite material. Background technique [0002] Polydicyclopentadiene (English abbreviation PDCPD) is an engineering plastic with high impact strength and high flexural modulus. The plastic has excellent heat resistance, creep resistance, dimensional stability, shape memory, Corrosion-resistant, wear-resistant, light-weight and other materials can be used to manufacture various high-performance, high-value-added, high-end fine products, such as: transportation (such as automobile bumpers, guard plates, side panels, engine covers and body shells, etc.), electrical equipment (such as the casing of large electrical equipment such as motors and air conditioners), sports equipment (such as components of snowmobiles, surfboards, golf carts, etc.), agricultural machinery, civil construction materials, etc. The Uni...
