Efficient cement concrete water reducing agent and preparation method thereof
The invention discloses an efficient cement concrete water reducing agent and a preparation method thereof. The efficient cement concrete water reducing agent comprises the following raw materials in parts by weight: 30-38 parts of methyl allyl polyoxyethylene ether, 8-10 parts of mercaptoacetic acid, 28-35 parts of dimethylaminoethyl methacrylate, 5-8 parts of dichloromethane, 12-16 parts of benzyl chloride, 12-16 parts of diethyl ether, 1-3 parts of a polymerization inhibitor, 2-5 parts of an initiator a, 3-6 parts of an initiator b and 15-26 parts of deionized water. According to the efficient cement concrete water reducing agent, dimethylaminoethyl methacrylate, dichloromethane and the polymerization inhibitor are adopted to prepare a monomer product, and methyl allyl polyoxyethylene ether is compounded so that a certain resistance effect on clay is achieved, the fluidity of cement paste is further effectively reduced, and the application range of the water reducing agent is widened; the whole preparation process guarantees the sealing performance of the materials, external pollution is avoided, and then the preparation quality of the cement concrete water reducing agent is effectively improved.
本发明公开了一种高效水泥混凝土减水剂及其制备方法，包括以下重量份原料甲基烯丙基聚氧乙烯醚30‑38份、巯基乙酸8‑10份、甲基丙烯酸二甲氨基乙酯28‑35份、二氯甲烷5‑8份、氯化苄12‑16份、乙醚12‑16份、阻聚剂1‑3份、引发剂a2‑5份、引发剂b3‑6份、去离子水15‑26份。该高效水泥混凝土减水剂，通过采用甲基丙烯酸二甲氨基乙酯、二氯甲烷和阻聚剂制备单体产物，复配甲基烯丙基聚氧乙烯醚，对粘土起到一定抵抗作用，进而有效的降低水泥浆体的流动度，提高减水剂的适用范围；整个制备流程保证物料的密封性，避免外界污染的发生，进而有效提高水泥混凝土减水剂的制备质量。
