Organic-inorganic composite modified high-strength and high-toughness cement-based material and preparation method thereof
The invention relates to an organic-inorganic composite modified high-strength and high-toughness cement-based material and a preparation method thereof.The cement-based material is obtained by adding a cementing material into an in-situ polymerization solution, and the cementing material and a polymer form a net-shaped structure; the cementing material is prepared from the following components in parts by weight: 140 to 200 parts of cement and 0 to 60 parts of admixture; the in-situ polymerization solution is prepared from the following components in parts by weight: 0.2 to 0.6 part of nano cellulose, 60 to 100 parts of water, 20 to 80 parts of acrylamide monomer, 0.1 to 2.0 parts of initiator and 0.1 to 1.0 part of cross-linking agent. Compared with the prior art, the invention has the characteristics of low cost, simple forming process, high breaking strength, high compressive strength, excellent toughness and the like.
本发明涉及一种有机‑无机复合改性的高强高韧性水泥基材料及制备方法，该水泥基材料通过将胶凝材料加入至原位聚合溶液中得到，所述胶凝材料与聚合物形成网状结构；所述胶凝材料包括以下重量份组分：水泥140‑200份和掺合料0‑60份；所述原位聚合溶液包括以下重量份组分：纳米纤维素0.2‑0.6份、水60‑100份、丙烯酰胺单体20‑80份、引发剂0.1‑2.0份和交联剂0.1‑1.0份。与现有技术相比，本发明具有成本低、成型工艺简单、高抗折强度、高抗压强度，韧性优异等特点。
