Abstract

The invention discloses a montmorillonite modified polytricyclopentadiene PTCPD composite material and a preparation method. The composite material comprises montmorillonite and a polytricyclopentadiene resin system, and the montmorillonite is uniformly dispersed in the polytricyclopentadiene resin system. Due to the fact that the molecular weight of tricyclopentadiene TCPD is large, the rigidity is large, and due to modification of montmorillonite, the bending modulus of the prepared montmorillonite modified polytricyclopentadiene PTCPD composite material can reach 4020-4460 MPa, and the technical problem that in the prior art, the rigidity of a polydicyclopentadiene PDCPD material is insufficient is solved. The montmorillonite modified polytricyclopentadiene composite material disclosed by the invention has the excellent characteristics of high strength, high storage modulus, good thermal stability and barrier property, acid resistance, alkali resistance, brine corrosion resistance, halogen gas corrosion resistance, fatigue resistance, capacity increase, cost reduction and the like, and is wide in application range.
