Abstract

The invention discloses a polydicyclopentadiene / polyacrylate composite material and a preparation method thereof. The polydicyclopentadiene / polyacrylate composite material is mainly prepared by blending and polymerizing the following monomers in parts by weight: 70-99 parts of dicyclopentadiene monomer, 1-30 parts of mono-acrylate monomer and 0.1-10 parts of diacrylate monomer. In the polydicyclopentadiene / polyacrylate composite material, the polyacrylate has favorable flexibility; the mono-acrylate monomer and the diacrylate monomer are combined to overcome the defect of low toughness of the polydicyclopentadiene; and compared with the single polydicyclopentadiene material, the impact strength of the polydicyclopentadiene / polyacrylate composite material is enhanced by more than 25% on the premise of keeping the original tensile strength.

Description

technical field [0001] The invention relates to a polydicyclopentadiene / polyacrylate composite material and a preparation method of the composite material, belonging to the technical field of polymer materials. Background technique [0002] An interpenetrating polymer network is a polymer alloy composed of two or more polymer macromolecules that are each cross-linked and interpenetrated. The "forced compatibility" in the formation process makes polymer molecules with different properties entangle with each other to form a compatible whole. Therefore, the polymer materials formed by this method have better performance. Polydicyclopentadiene (PDCPD) is an engineering plastic with high impact resistance and high modulus, which is polymerized from dicyclopentadiene monomer (DCPD) under the action of a ring-opening metathesis catalyst. Catalyst systems currently in use include aryl or aryloxytungsten, molybdenum complexes or carbene catalysts of molybdenum, ruthenium and osmium....
