Air-entraining type slurry purifying agent mother liquor as well as preparation method and application thereof
The invention discloses an air-entraining type slurry extracting agent mother liquor and a preparation method and application thereof, and the solid content of the air-entraining type slurry extracting agent mother liquor is 35-45wt%. The invention relates to a polycarboxylate superplasticizer, which is characterized by being prepared from the following raw materials in parts by mass: 5 to 50 parts of polyoxyethylene macromonomer, 3 to 30 parts of unsaturated carboxylic acid or/and unsaturated anhydride, 0.3 to 6 parts of sodium alpha-olefin sulfonate, 0.003 to 7 parts of monoepoxy-terminated unsaturated compound, 0.001 to 2.5 parts of cross-linking agent, 0.3 to 1.5 parts of redox initiation composition and water. The raw materials are subjected to polymerization reaction to form an interpenetrating network structure, after the interpenetrating network structure is doped into concrete, the wrapping property of concrete mixture slurry can be obviously improved, the size of air beads is reduced, the floating, dissipation and coalescence processes of the small air beads in aggregate gaps are inhibited, and the uniform dispersion of the small air beads in the concrete can be improved and kept; the concrete workability and workability are improved, the concrete strength design grade is guaranteed, the volume weight of a concrete mixture is obviously reduced, and the fluidity of the concrete is improved.
本发明公开了一种引气型提浆剂母液及其制备方法和应用，引气型提浆剂母液的固含量为35‑45wt％，且由包括如下质量份的组分在内的原料制得：5‑50份聚氧乙烯基大单体、3‑30份不饱和羧酸或/和不饱和酸酐、0.3‑6份α‑烯基磺酸钠、0.003‑7份单环氧基封端不饱和化合物、0.001‑2.5份交联剂、0.3‑1.5份氧化还原引发组合物和水。上述各原料通过聚合反应形成互穿网络结构，掺用于混凝土后能明显提升混凝土拌合物浆体的包裹性、减小气珠的尺寸、抑制微小气珠在集料间隙上浮、逸散和聚并的过程，提高并能保持小气珠在混凝土中的匀质分散，改善混凝土和易性和工作性，并在保障混凝土强度设计等级的同时明显降低混凝土拌合料的容重、增加混凝土的流动性。
