Method for preparing graphene reinforced nonmetal-based composite material by combining step-by-step feeding with hot pressing and hot isostatic pressing sintering
The invention discloses a method for preparing a graphene reinforced non-metal-based composite material by combining step-by-step feeding with hot pressing and hot isostatic pressing sintering. The method comprises the following steps: a, putting a graphene reinforcement into a ball milling tank, adding a non-metal material and grinding balls, adding a grinding aid into the ball-milling tank multiple times for ball-milling until the raw materials are mixed into uniform paste, and drying the ball-milled paste to obtain composite powder; and b, sequentially carrying out vacuum hot pressing sintering treatment and hot isostatic pressing sintering treatment on the composite powder to prepare the graphene reinforced non-metal-based composite material. According to the invention, by adopting a step-by-step charging and ball milling mode, graphene can be uniformly dispersed in a matrix material, the dispersion efficiency is high, the dispersion stability is high, the graphene structure is not damaged, and the problem that the graphene is easy to agglomerate is solved; and the graphene reinforced nonmetal-based composite material obtained by combining step-by-step charging and ball milling, hot pressed sintering and hot isostatic pressing sintering has the most excellent mechanical property, and can meet the requirements of industrial preparation.
本发明公开了一种分步加料与热压和热等静压烧结相结合制备石墨烯增强非金属基复合材料的方法，包括a.先将石墨烯增强体放入球磨罐中后再加入非金属材料和磨球，然后分多次向球磨罐中加入助磨剂进行球磨直至原料混合呈均匀浆糊状，将球磨后的浆料干燥制得复合粉料；b.将复合粉料先后经真空热压烧结处理和热等静压烧结处理，制得石墨烯增强非金属基复合材料。采用分步加料球磨的方式能够使石墨烯均匀分散于基体材料中且分散效率高、分散稳定性高、对石墨烯结构无破坏，解决石墨烯易团聚的问题。通过分步加料球磨和热压烧结与热等静压烧结相结合获得的石墨烯增强非金属基复合材料具有最优异的力学性能，而且能够满足工业化制备的要求。
