Cement-based material internal curing agent as well as rapid preparation method and application thereof
The invention discloses a cement-based material internal curing agent and a rapid preparation method and application thereof, and belongs to the technical field of internal curing agent preparation. In order to reduce the production cost of the cement-based material internal curing agent, a monomer, a raw material, an initiator and a cross-linking agent are weighed, the mass ratio of the monomer to the raw material is (3-5): 1, the initiator accounts for 0.8-1.8 wt% of the mass of the monomer, and the cross-linking agent accounts for 0.08-0.9 wt% of the mass of the hydrophilic monomer; preparing a monomer solution, a raw material solution, an initiator solution and a cross-linking agent solution; mixing the raw material solution and the initiator solution, standing for 10-15 minutes under a water bath condition, adding the monomer solution and the cross-linking agent solution, uniformly stirring, standing and reacting for 2.5-3.5 hours to obtain a reaction product, washing the reaction product with tap water until the washing solution is neutral, washing with an ethanol solution, and drying in a drying oven until the weight is constant, so as to obtain the composite material. And crushing by using a crusher to obtain the cement-based material internal curing agent.
一种水泥基材料内养护剂及其快速制备方法及其应用，属于内养护剂制备技术领域。为了降低水泥基材料内养护剂制备的生产成本，本发明称量单体、原材料、引发剂、交联剂，单体和原材料的质量比为3‑5:1，引发剂为单体质量的0.8‑1.8wt％，交联剂为亲水单体质量的0.08‑0.9wt％；配置成单体溶液、原材料溶液、引发剂溶液、交联剂溶液；将原材料溶液和引发剂溶液混合在水浴条件下静置10‑15分钟后，再加入单体溶液、交联剂溶液，搅拌均匀后静置反应2.5‑3.5小时后，得到反应产物用自来水洗涤直到洗涤溶液为中性，再用乙醇溶液洗涤，在烘箱中干燥至恒重，然后用破碎机进行破碎处理，得到一种水泥基材料内养护剂。
