Abstract

The invention belongs to the technical field of novel materials, and particularly relates to a polydicyclopentadiene composite material and a reaction injection molding process thereof. The compositematerial comprises a component A and a component B, wherein the component A comprises dicyclopentadiene, a boron trifluoride diethyl etherate complex, titanocene dichloride and glass fibers; the massratio of dicyclopentadiene, the boron trifluoride diethyl etherate complex, and the titanocene dichloride is (100-300):1:0.1; the mass of the added glass fibers is 0.1-1% of the mass of the dicyclopentadiene; the component B comprises dicyclopentadiene, a ruthenium carbene catalyst and carbon fibers; the mass ratio of the dicyclopentadiene to the ruthenium carbene catalyst is (100-200):1; and themass of the added carbon fibers is 0.1-0.5% of the mass of the dicyclopentadiene. Compared with the prior art, the polydicyclopentadiene composite material and the reaction injection molding process thereof provided by the invention have the advantages that through scientific matching of the auxiliaries and the auxiliary materials, the strength of a finished product is effectively improved while the finished product has high toughness, so that the service lifetime of the product is prolonged.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a polydicyclopentadiene composite material and a reaction injection molding process thereof. Background technique [0002] Polydicyclopentadiene (abbreviated as PDCPD) engineering plastics is a new type of engineering material with good comprehensive mechanical and physical properties. It also has high impact strength, high flexural modulus (toughness index), high hardness, high heat Deformation temperature and very good anti-aging properties. This technology belongs to the high-tech encouraged by the state, and the manufacturing process is flexible and simple, especially suitable for making ultra-thin parts with high strength and large area. [0003] Therefore, it shows a very broad application prospect in the fields of automobile industry, engineering machinery manufacturing, medical and sports equipment, petrochemical pipelines and civil facilities. Especia...
