Multistage interpenetrating network modified cement-based composite material and preparation method thereof
The invention discloses a multi-stage interpenetrating network modified cement-based composite material which is prepared from the following components in parts by mass: 90 to 100 parts of cementing material, 1 to 5 parts of multipolymer monomer, 0.001 to 0.003 part of cross-linking agent, 0.005 to 0.015 part of initiator, 0.005 to 0.04 part of catalyst, 0.01 to 0.5 part of nano cellulose, 0.15 to 0.25 part of defoaming agent, 0.5 to 1.5 parts of water reducing agent, 0 to 1.4 parts of sodium hydroxide and 35 to 55 parts of mixing water. According to the multi-stage interpenetrating network modified cement-based composite material adopting the components and the preparation method of the multi-stage interpenetrating network modified cement-based composite material, a multi-polymer monomer is used as a first-stage network, cellulose nanofibers are used as a second-stage network, and the multi-stage interpenetrating network modified cement-based composite material is prepared through the in-situ polymerization and synchronous induction preparation method. And forming the multi-stage interpenetrating network cement-based composite material which is uniformly entangled with a cementing material hydration product.
本发明公开了一种多级互穿网络改性水泥基复合材料，各组分按质量份数为：胶凝材料90‑100份、多元聚合物单体1‑5份、交联剂0.001‑0.003份、引发剂0.005‑0.015份、催化剂0.005‑0.04份、纳米纤维素0.01‑0.5份、消泡剂0.15‑0.25份、减水剂0.5‑1.5份、氢氧化钠0‑1.4份和拌和水35‑55份。本发明采用上述组分的一种多级互穿网络改性水泥基复合材料及其制备方法，以多元聚合物单体为一级网络，纤维素纳米纤维为二级网络，通过原位聚合与同步诱导的制备方法，形成与胶凝材料水化产物均匀缠结的多级互穿网络水泥基复合材料。
