Cement grinding aid synergist containing disulfide bond polymer as well as preparation method and application of cement grinding aid synergist
The invention relates to a cement grinding aid synergist containing a disulfide bond polymer as well as a preparation method and application of the cement grinding aid synergist, and belongs to the field of concrete admixtures. The cement grinding aid synergist comprises a disulfide bond-containing polymer and a disulfide bond reversible regulation catalyst, the disulfide bond-containing polymer is prepared from the following raw materials in parts by weight: 5 to 100 parts of carboxyl-containing monomer, 5 to 100 parts of sulfo group-containing monomer, 1 to 50 parts of unsaturated monomer, 0.1 to 10 parts of disulfide bond-containing monomer, 10 to 300 parts of alkali, 100 to 5000 parts of solvent and 0.1 to 20 parts of catalyst. The obtained cement grinding aid synergist has the advantages of dissolubility, easiness in construction, good cohesiveness and capability of forming a three-dimensional cross-linked network through molecular rearrangement after construction; when the cement grinding aid is added into the cement grinding aid to be applied to concrete, the obtained concrete has excellent strength performance and anti-aging performance.
本发明涉及含二硫键聚合物的水泥助磨增效剂及其制备方法和应用，属于混凝土外加剂领域。所述水泥助磨增效剂包括含二硫键聚合物和二硫键可逆调控催化剂；所述含二硫键聚合物由以下组分的原料制备而成：含羧基单体5～100重量份，含磺酸基单体5～100重量份，不饱和单体1～50重量份，含二硫键单体0.1～10重量份，碱10～300重量份，溶剂100～5000重量份，催化剂0.1～20重量份。所得水泥助磨增效剂具有可溶解、易施工、良好的粘聚性及施工后分子重排形成三维交联网络的优点；当将其添加至水泥助磨剂中而应用到混凝土中时，所得混凝土具有优异的强度性能和抗老化性能。
