A composite material, its preparation and use

By introducing silane coupling agents to modify basalt flakes and self-healing microcapsules into the rubber material of marine biological protection devices, the problems of insufficient weather resistance and self-healing performance of existing materials in marine environments have been solved. This has achieved synergistic effects of UV resistance, salt spray resistance, and high wear resistance, thus extending the service life of the device.

Abstract

This invention relates to a composite material, its preparation method, and its applications. The raw materials for preparing the composite material include the following components: ethylene propylene diene monomer (EPDM) rubber, silane coupling agent-modified basalt flakes, self-healing microcapsules, reinforcing fillers, crosslinking agents, antioxidants, light stabilizers, plasticizers, and lubricants. This invention utilizes a fixed and stable microcapsule system, synergistically compounding it with basalt flake EPDM rubber to prepare a rubber composite material possessing excellent UV resistance, salt spray resistance, high wear resistance, and self-healing crack properties.
