AI Technical Summary

Technical Problem

Existing polydicyclopentadiene materials are prone to warping, deformation, and insufficient dimensional stability in finished products, and are also prone to aging in outdoor environments. Existing modification methods are difficult to simultaneously meet the requirements of high resistance to deformation and long-term service reliability.

Method used

By leveraging the synergistic effects of low-shrinkage structural monomers, imine dynamic components, functionalized inorganic reinforcing fillers, and rigid UV-absorbing molecules, high-deformation-resistant and weather-resistant polydicyclopentadiene composite materials are prepared through high-pressure impact mixing and reaction injection molding, achieving controllable volume shrinkage, releaseable internal stress, interface reinforcement, and weather protection.

Benefits of technology

It significantly reduces warpage and deformation of materials during polymerization and service, improves dimensional stability and long-term outdoor weather resistance, while maintaining simple processing and ease of industrial application, thereby enhancing service reliability and service life.
