Waterproof cyanuric chloride modified graphene/nitrocellulose composite material as well as preparation method and application thereof

The invention discloses a waterproof cyanuric chloride modified graphene/nitrocellulose composite material. The waterproof cyanuric chloride modified graphene/nitrocellulose composite material is prepared from 2 to 200 parts of cyanuric chloride modified graphene, 1000 parts of nitrocellulose and 1 to 50 parts of Lewis acid. The cyanuric chloride modified graphene has good hydrophobicity, the Lewis acid serves as a cross-linking agent, free active functional groups on a long chain of nitrocellulose can be cross-linked, and a more compact cross-linked structure is formed. After being grafted with nitrocellulose, the cyanuric chloride modified graphene/nitrocellulose composite material has better dispersing performance, and the particle size distribution coefficient is less than or equal to 0.5. 本发明公开了一种防水型三聚氯氰改性石墨烯/硝化纤维素复合材料，包括三聚氯氰改性石墨烯2-200份、硝化纤维素1000份、路易斯酸1-50份；本申请的三聚氯氰改性石墨烯具有较好的疏水性，路易斯酸则是充当交联剂的作用，可将硝化纤维素长链上游离的活性官能团交联，形成更致密的交联结构。与硝化纤维素接枝后，三聚氯氰改性石墨烯/硝化纤维素复合材料具有较好的分散性能，粒径分布系数≤0.5。
