Abstract

The invention discloses a multicolor ageing-resistant spraying-free polydicyclopentadiene composite material, and a preparation method and an application thereof. Raw materials for preparing the composite material comprise 35-65% of dicyclopentadiene, 1-15% of a copolymer, 10-35% of a functional filler, 0.05-5% of environmentally-friendly color paste or high-mesh toner, and 0.01-0.1% of a ruthenium carbene catalyst. The material is integrally formed after high-efficiency dissolution of the environmentally-friendly color paste or the high-mesh toner with dicyclopentadiene, full mixing of the obtained material with other ingredients, reaction of the obtained mixture with a curing agent, and injection molding polymerization. The spraying-free polydicyclopentadiene composite material has the advantages of brilliant color, ageing resistance, long life, superior mechanical performances, and simple repairing of minimal scratches, and the preparation method is simple.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a multi-color, anti-aging spray-free polydicyclopentadiene composite material and its preparation method and application. Background technique [0002] As an engineering plastic, polydicyclopentadiene (abbreviated as PDCPD) 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 distortion temperature and good anti-aging performance, flexible and simple manufacturing process, especially suitable for making ultra-thin parts with high strength and large area. [0003] It has shown a very broad application prospect in the fields of automobile industry, construction machinery manufacturing, medical and sports equipment, petrochemical pipelines and civil facilities. Especially famous companies such as Caterpillar, Terex, Liebh...
