Preparation method of nanocellulose/glutinous rice mortar hybrid material
The invention discloses a preparation method of a nanocellulose/glutinous rice mortar hybrid material. The preparation method comprises the following steps: S1, preparing nanocellulose powder; s2, adding a certain amount of nano cellulose powder into a certain amount of glutinous rice pulp, and fully stirring and uniformly mixing to obtain a mixed solution a; s3, adding a certain amount of calcium hydroxide into the mixed solution a, and stirring for 1-3 hours under the condition of 400-600 rpm to obtain a mixed solution b; and S4, performing injection molding on the mixed solution b, and curing for 30-150 days under the conditions that the humidity is 50-75% and the temperature is 20-25 DEG C to obtain the nano cellulose/glutinous rice mortar composite material. Biomass polysaccharide cellulose is added into the glutinous rice mortar, and the cellulose has the properties of biological polysaccharide and also has the characteristics of good toughness, high strength and the like, so that the nano cellulose/glutinous rice mortar composite material is prepared. The constructed cellulose and glutinous rice mortar compounded nano cementing material can more scientifically and reasonably use and exert the advantages of the glutinous rice mortar and the lime, and has important significance on ancient building site repair engineering.
本发明公开了一种纳米纤维素/糯米灰浆杂化材料的制备方法，包括以下步骤：步骤S1、制备纳米纤维素粉末；步骤S2、将一定量的纳米纤维素粉末加入一定量的糯米浆中，充分搅拌混合均匀，得到混合溶液a；步骤S3、在混合溶液a中加入一定量的氢氧化钙，在400‑600rpm的情况下搅拌1‑3h，得到混合溶液b；步骤S4、将混合溶液b注模成型，在湿度50％‑75％，温度20‑25℃条件下，固化30‑150天，得到纳米纤维素/糯米灰浆复合材料，本发明将生物质多糖纤维素加入糯米灰浆中,利用纤维素具有生物多糖的性质,同时又具有韧性好、强度高等特性,构建纤维素糯米灰浆复合的纳米胶凝材料可以更加科学合理地使用和发挥糯米浆和石灰的优势,对于古建遗址修复工程具有重要意义。
