Nano-modified organic-inorganic composite thixotropic admixture and preparation method thereof
The invention discloses a nano-modified organic-inorganic composite thixotropic additive and a preparation method thereof. The nano-modified organic-inorganic composite thixotropic additive is prepared from the following components in parts by mass: 5.0 to 25.0 parts of aerated concrete chippings, 0.01 to 0.08 part of polyethylene glycol, 0.02 to 0.08 part of polyvinyl alcohol, 5.0 to 30.0 parts of cellulose ether, 0 to 5.0 parts of welan gum, 0 to 5.0 parts of diding gum, 0 to 5.0 parts of welan gum and the balance of water. The preparation method comprises the following steps: sequentially adding water, aerated concrete chippings, polyethylene glycol and polyvinyl alcohol into a ball mill, carrying out ball milling for 30-360 minutes, sequentially adding cellulose ether, Welan glue, diding glue and Welan glue, and continuously carrying out ball milling for 5-10 minutes. The thixotropic agent can effectively improve the thixotropy of freshly mixed mortar or concrete.
本发明公开了一种纳米改性有机无机复合触变外加剂及其制备方法，包括如下质量分数的组分：加气混凝土碎屑5.0‑25.0份、聚乙二醇0.01‑0.08份、聚乙烯醇0.02‑0.08份、纤维素醚5.0‑30.0份、温伦胶0‑5.0份、定优胶0‑5.0份、文莱胶0‑5.0份，余量为水。在球磨机中依次加入水、加气混凝土碎屑、聚乙二醇和聚乙烯醇，球磨30‑360min，再依次加入纤维素醚、温伦胶、定优胶和文莱胶，继续球磨5‑10min后制备而成。本发明可以有效提升新拌砂浆或混凝土触变性。
