Graphene oxide nano-modified cement-based grouting material and preparation method thereof
The invention belongs to the technical field of cement-based grouting materials. The invention provides a graphene oxide nano-modified cement-based grouting material. The graphene oxide nano-modifiedcement-based grouting material is prepared from the following components in parts by mass: 85-95 parts of cement; 0.5-1.5 parts of a polycarboxylate superplasticizer; 0.01-0.04 part of graphene oxide;0.01-0.05 part of a carbon nano tube; 1.2-3 parts of a shrinkage reducing agent; 3-5 parts of a suspending agent; 5-8 parts of an expanding agent; 3-7 parts of an inorganic powder material; and 40-45parts of water. According to the invention, the nanoscale capillary pores in the cement-based grouting material are filled with the graphene oxide, so that a bridging effect is formed in micron-scalegel pores of the cement-based grouting material, and the anti-permeability performance of the cement-based grouting material is reinforced; the carbon nanotubes can increase the microcosmic adhesioneffect of the consolidation body surface of the cement-based grouting material to other substances, so that the service life of the cement-based grouting material can be remarkably prolonged.
本发明属于水泥基注浆材料技术领域。本发明提供了一种氧化石墨烯纳米改性水泥基注浆材料，由包括如下质量份的组分制备而成：水泥85～95份；聚羧酸减水剂0.5～1.5份；氧化石墨烯0.01～0.04份；碳纳米管0.01～0.05份；减缩剂1.2～3份；悬浮剂3～5份；膨胀剂5～8份；无机粉体材料3～7份；水40～45份。本发明的氧化石墨烯充填水泥基注浆材料中的纳米级毛细孔，在水泥基注浆材料微米级凝胶孔中形成桥接作用，对其抗渗性能起到加固作用，碳纳米管能增大水泥基注浆材料固结体表面对其他物质的微观粘附作用；本发明能够显著延长水泥基注浆材料的使用寿命。
