Abstract

The invention discloses a polytricyclopentadiene (PTCPD) foam material and a preparation method thereof. The material is prepared from the following components: tricyclopentadiene (TCPD), a catalyst and a foaming agent, wherein the weight percentage of the TCPD is 51%-99%. As the molecular weight of the TCPD is large, the rigidity of the TCPD is large, and the rigidity of the prepared PTCPD foam material is far greater than that of an existing polydicyclopentadiene (PDCPD) high polymer material. Meanwhile, the foaming agent is added, so that gaps exist in the material, the volume is increased, the density is reduced, and the whole material has the characteristics of high strength and light weight. Meanwhile, the PTCPD high polymer material also has excellent characteristics of acid resistance, alkali resistance, seawater corrosion resistance, fatigue resistance and the like, and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polytricyclopentadiene PTCPD foam material and a preparation method thereof. Background technique [0002] Polydicyclopentadiene PDCPD polymer material is a homopolymer or copolymer of dicyclopentadiene DCPD, which is a cross-linked three-dimensional network structure engineering plastic.
