The invention further discloses apreparation method of the high-strength anti-aging PPO composite material filled with the nanometer mesoporous silicon.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and more specifically, the invention relates to a high-strength anti-aging PPO composite material filled with nanometer mesoporous silicon. Background technique [0002] Polyphenylene ether (PPO) is one of the five major engineering plastics. PPO is an amorphous material with high lipophilicity, excellent heat resistance, electrical insulation and creep resistance at high temperature, but its impact toughness is poor, difficult to process and not resistant to non-polar solvents; in addition, there are limited strength and resistance The defect of poor flammability needs to be solved urgently. [0003] Therefore, technical improvements are needed to prepare PPO composites with better strength and high elasticity, and better flame retardancy. Contents of the invention [0004] In order to solve the above problems, one aspect of the present invention provides a high-strength ...
