Concrete workability regulator and preparation method thereof
The invention discloses a concrete workability regulator and a preparation method thereof. The preparation method comprises the following steps: adding acrylic acid, maleic anhydride, propanesulfonicacid and allyl phosphate into a reaction container, exhausting air, and increasing the temperature to 10-40 DEG C; and adding an initiator to react for 1-2 hours to obtain the workability regulator. The mass percentages of the raw materials are as follows: 25-50% of acrylic acid, 5-30% of maleic anhydride, 1-10% of propanesulfonic acid and 1-30% of allyl phosphate. When the concrete workability regulator is added into concrete, a large number of anions can be instantly generated, adsorption points on cement particles can be preempted, the anions can be balanced with cations in the atmosphere,and the cohesiveness of the concrete can be effectively improved through the special physical magnetic field effect of the concrete workability regulator. Meanwhile, raw material cost is low, reactionconditions are mild, no extra reaction solvent needs to be added, and the concrete workability regulator is environmentally friendly and suitable for application and popularization.
本发明公开了一种混凝土和易性调节剂及其制备方法，包括以下步骤：将丙烯酸、马来酸酐、丙磺酸、烯丙基磷酸酯加入反应容器中，排尽空气升温至10～40℃；加入引发剂反应1～2小时，得和易性调节剂。各原料按质量百分比计为：丙烯酸25～50％、马来酸酐5～30％、丙磺酸1～10％，烯丙基磷酸酯1～30％。所得混凝土和易性调节剂加入混凝土中可瞬间产生大量阴离子，可抢占水泥颗粒上的吸附点，也可与大气中阳离子相平衡，其特殊的物理磁场效应可有效提升混凝土的粘聚性。同时原料成本低、反应条件温和，无需额外添加反应溶剂，环境友好，适合推广应用。
