Abstract

The invention discloses an oil-containing poly-dicyclopentadiene composite material and a preparation method thereof. The poly-dicyclopentadiene composite material is mainly prepared by catalytically blending and polymerizing the following raw materials in parts by weight: 70-95 parts of dicyclopentadiene and 5-30 parts of lubricating oil. The lubricating oil is paraffin oil, silicone oil or heavy liquid paraffin. The lubricating oil is blended with the poly-dicyclopentadiene to obtain the poly-dicyclopentadiene composite material, so the wear resistance of the composite material under dry friction conditions is obviously enhanced, the antiwear performance is 2-3 times higher than that in the prior art, and the high holding modulus and high shock strength of the composite material are maintained; and thus, the composite material can be used for preparing parts having wider application range.
