Method for preparing graphene reinforced non-metal-based composite material by combining step-by-step feeding and multiple pressure sintering
The invention discloses a method for preparing a graphene reinforced non-metal-based composite material by combining step-by-step feeding and multiple pressure sintering, which comprises the following steps of a, putting a graphene reinforcement into a ball milling tank, then adding a non-metal material and grinding balls, then adding a grinding aid into the ball milling tank for multiple times, and carrying out ball milling until the raw materials are mixed into uniform paste, drying the ball-milled slurry to obtain composite powder, and b, treating the composite powder by more than two pressure sintering processes to prepare the graphene reinforced non-metal-based composite material. According to the method, step-by-step feeding and ball milling are adopted, then pressure sintering treatment is conducted in multiple modes, graphene can be evenly dispersed in a base material through the step-by-step feeding and ball milling mode, the dispersion efficiency is high, the dispersion stability is high, the graphene structure is not damaged, and the problem that graphene is prone to agglomeration is solved; inthe multiple sintering stages of composite materials, the sintering temperature can be effectively reduced by adopting low-temperature air pressure, heat and other sintering technologies, the energy consumption is reduced, and the mechanical property of the material is improved.
