Graphene oxide reinforced geopolymer and preparation method thereof
The invention relates to a graphene oxide reinforced geopolymer which is prepared from the following raw materials in parts by weight: 100 parts of a silicon-aluminum raw material, 50-85 parts of an alkali activator, 0.01-0.07 part of graphene oxide and 0.02-0.20 part of a dispersing agent; wherein the silicon-aluminum raw material is selected from any one or a mixture of more than two of metakaolin, coal gangue, fly ash or slag in any proportion. According to the invention, with the low cost aluminosilicate material as a main raw material and graphene as filler, the prepared geopolymer product is high in flexural strength and compressive strength, good in toughness, good in acid and alkali resistance and good in high temperature resistance, so that the problems existing in an existing geopolymer modification technology are effectively solved. In addition, the preparation process is simple, raw material sources are rich, the CO2 emission amount is small, the additional value of the product is high, and good economic benefits and environmental protection benefits are achieved.
本发明涉及一种氧化石墨烯增强地聚合物，由如下重量份的原料制备而成：100份硅铝质原料，50‑85份碱激发剂，0.01‑0.07份氧化石墨烯，0.02‑0.20份分散剂；所述硅铝质原料选自偏高岭土、煤矸石、粉煤灰或矿渣中的任意一种或二种以上任意比例的混合物。本发明以廉价硅铝酸盐材料为主要原料，以石墨烯为填料，制备的地聚合物产品的抗折以及抗压强度高、韧性好、耐酸碱性好、耐高温性好，有效地改善了现在地聚合物改性技术存在的问题，并且制备工艺简单，原料来源丰富、CO排放量小，产品附加值高，具有良好的经济效益和环保效益。
