Abstract

The invention relates to a method for graphene-reinforced metal materials. First, water-based titanate is dissolved in water, then graphene powder is added, and ultrasonic treatment is performed in a magnetic field to obtain a graphene dispersion; the dispersion is processed in an external magnetic field. Distillation or vacuum distillation to obtain the graphene concentrate, and then dry it to obtain the graphene modified by aqueous titanate, add the modified graphene and metal powder to the ethanol solution, and the mixture formed after ultrasonic dispersion is ball milled , drying, and sintering to obtain a graphene-enhanced metal material. The present invention carries out dehydration treatment such as distillation and drying on the dispersion liquid, can effectively expand the application field of the modified graphene, greatly improves the shortcomings and drawbacks that occur when graphene is applied, and finally the dried graphite modified by water-based titanate Adding olefin to the metal material composite system can significantly improve the strength and electrical and thermal conductivity of the composite material.
