Abstract

The invention discloses a poly-dicyclopentadiene foam material and a preparation method thereof. The poly-dicyclopentadiene foam material includes following raw materials, by weight, 100 parts of dicyclopentadiene, 0.2-2 parts of a foaming agent, 0.5-5 parts of a viscosity-increasing agent, 0.2-2 parts of a nucleating agent, a main catalyst and a co-catalyst. The poly-dicyclopentadiene foam material is thermosetting microporous hard plastic foam which has functions of low density, heat insulation and sound insulation with an originally high strength being maintained so that a problem that a high strength and a light weight cannot be achieved at the same time in a poly-dicyclopentadiene foam material in the prior art. The method effectively saves a usage amount of a monomer raw material, reduces the cost of the material, can effectively broaden application scopes of the poly-dicyclopentadiene foam material and has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of polydicyclopentadiene, specifically relates to a polydicyclopentadiene foam material, and also relates to a preparation method of the polydicyclopentadiene foam material. Background technique [0002] Polydicyclopentadiene (PDCPD for short) is a moderately cross-linked thermosetting plastic obtained by ring-opening transposition polymerization of dicyclopentadiene. obtained by dimerization of olefins. Since dicyclopentadiene contains two unsaturated double bonds, its chemical properties are very active, and it can react with a variety of compounds to generate a wide variety of derivatives. Therefore, PDCPD is a polymer chain with a rigid five-membered ring, and the shape A thermosetting plastic in the shape of a net or body, with good mechanical properties, especially suitable for surface decoration and structural parts; in addition, it also has the advantages of chemical corrosion resistance, low water ...
