Graphene oxide-silane coupling agent-geopolymer composite material and preparation method thereof
The invention relates to a graphene oxide-silane coupling agent-geopolymer composite material. The composite material is prepared from the following raw materials in parts by weight: 100 parts of a silicon-aluminum raw material, 35-80 parts of an alkali activator, 0.7-7.0 parts of a silane coupling agent hydrolysate, 0.01-0.07 part of graphene oxide and 0.03-0.20 part of a dispersing agent. According to the invention, a cheap silicon-aluminum material is used as a raw material which is rich in source and low in cost, and the graphene oxide is used as a filler, so the prepared geopolymer-basedcomposite material is high in flexural strength and compressive strength, good in toughness, good in acid and alkali resistance and good in high-temperature resistance, and the problems of high brittleness, poor toughness and the like of an existing geopolymer are effectively improved; and the preparation method is simple in preparation process, small in CO2 emission, good in economical performance and friendly to environment; the geopolymer disclosed by the invention is rich in main raw material source and low in cost, can realize effective utilization of industrial solid wastes, and has goodeconomic benefits and environmental protection benefits.
本发明涉及一种氧化石墨烯‑硅烷偶联剂‑地聚合物复合材料，由如下重量份的原料制备而成：100份硅铝质原料，35‑80份碱激发剂，0.7～7.0份硅烷偶联剂水解液，0.01～0.07份氧化石墨烯，0.03～0.20份分散剂。本发明以廉价的硅铝质材料为原料，来源丰富、成本低廉，以氧化石墨烯为填料，制得的地聚合物基复合材料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，有效地改善了目前地聚合物存在的脆性大、韧性差等问题，并且制备工艺简单，CO排放量小，经济环保；本发明的地聚合物主体原料来源丰富、成本低廉，可实现对工业固废的有效利用，具有良好的经济效益和环保效益。
