Abstract

The invention discloses a flame-retardant polydicyclopentadiene composition, and a thermosetting material and a preparation method thereof. The composition comprises a dicyclopentadiene monomer, a catalyst, and moderate-low molecular weight bromide polymer capable of being dissolved in monomer dicyclopentadiene, and also can comprise other cycloolefins capable of being copolymerized with dicyclopentadiene, a synergistic flame retardant, a flame retardant synergist, other aids and the like. A main flame retardant in the composition can be dissolved in the monomer dicyclopentadiene, and is small in dosage and good in flame retardant effect. The composition can be prepared into the thermosetting material according to a reaction injection molding process, and the material has good comprehensive performance.

Description

Technical field

[0001] The invention relates to the field of polydicyclopentadiene resins, in particular to a flame-retardant polydicyclopentadiene composition and a thermosetting material and a preparation method thereof. Background technique

[0002] Dicyclopentadiene (DCPD) monomer adopts reaction injection molding (RIM) process under a two-component catalytic system to obtain high impact polydicyclopentadiene (PDCPD) through ring opening shift polymerization (ROMP) (US4400340) . DCPD is polymerized and interwoven into a network with excellent rigidity and toughness; it has both high impact resistance and high flexural modulus; at the same time it has good dimensional stability, acid and alkali resistance; excellent coating, electrical insulation and bonding properties; One-step rapid prototyping into large-volume, complex-structured parts, so it is widely used as a substitute for metal materials in civil engineering, communications, machinery, sports equipment, etc. At pres...
