Cement fluidizing agent and preparation method thereof
The invention relates to the technical field of cement admixtures, and particularly discloses a cement fluidizing agent and a preparation method thereof. The cement fluidizing agent comprises the following raw materials in parts by weight: 15-40 parts of acrylic acid, 8-35 parts of modified triethanolamine, 3-8 parts of polyethylene glycol monoallyl ether, 2-7 parts of calcium lignosulphonate, 8-15 parts of glycerol, 2-6 parts of an initiator, 5-9 parts of sodium hydroxide and 30-80 parts of water. The preparation method comprises the following steps: uniformly mixing acrylic acid and water to obtain an acrylic acid solution; uniformly mixing an acrylic acid solution, modified triethanolamine, polyethylene glycol monoallyl ether and calcium lignosulphonate, heating, dropwise adding an initiator, preserving heat, cooling, adding sodium hydroxide, and uniformly mixing to obtain a semi-finished product; and uniformly mixing the semi-finished product with glycerol to obtain the cement fluidizing agent. The cement fluidizing agent disclosed by the invention has the advantage of improving the strength of cement through the synergistic effect of the raw materials.
本申请涉及水泥外加剂的技术领域，具体公开了一种水泥流化剂及其制备方法。水泥流化剂包括以下重量份的原料：丙烯酸15‑40份、改性三乙醇胺8‑35份、聚乙二醇单烯丙基醚3‑8份、木质素磺酸钙2‑7份、丙三醇8‑15份、引发剂2‑6份、氢氧化钠5‑9份、水30‑80份；其制备方法为：将丙烯酸和水混匀，得到丙烯酸溶液；将丙烯酸溶液、改性三乙醇胺、聚乙二醇单烯丙基醚、木质素磺酸钙混匀，升温，滴加引发剂，保温，降温，加入氢氧化钠，混均匀，得到半成品；将半成品和丙三醇混匀，得到水泥流化剂。本申请的水泥流化剂，通过原料之间的协同作用，具有提高水泥强度的优点。
