Method for preparing graphene reinforced nonmetal-based composite material by adopting step-by-step charging ball milling and hot pressed sintering
The invention discloses a method for preparing a graphene reinforced nonmetal-based composite material by adopting step-by-step charging ball milling and hot pressed sintering, the method comprises the following steps: a, firstly 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; b, the composite powder is subjected to vacuum hot pressing sintering treatment so that the graphene reinforced nonmetal-based composite material is prepared. By adopting a step-by-step charging and ball milling mode, the graphene can be uniformly dispersed in the 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. Through combination of step-by-step feeding ball milling and hot pressing sintering, the sintering temperature can be effectively reduced, energy consumption is reduced, and the obtained graphene reinforced nonmetal-based composite material has the most excellent mechanical property and can meet the requirements of industrial preparation.
本发明公开了一种采用分步加料球磨与热压烧结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.将复合粉料采用真空热压烧结处理，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结合能能有效降低烧结温度，减少能耗，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。
