Super absorbent resin suitable for concrete alkaline environment and preparation method thereof
The invention provides super absorbent resin suitable for a concrete alkaline environment and a preparation method thereof, the preparation method comprises the following steps of: fully stirring anduniformly mixing a monomer solution, an initiator solution and a cross-linking agent solution according to a formula ratio, and further fully dispersing the initiator solution and the cross-linking agent solution in the monomer solution to obtain a mixed solution; and heating the mixed solution in a stepped manner. The invention has the advantages that: 1, the preparation method of the super absorbent resin can realize standing polymerization in a water bath kettle, the production equipment is simple, and the cost is low; 2, the super absorbent resin prepared by the preparation method of the super absorbent resin has excellent water absorption rate, and can be used as an excellent water replenishing agent for replenishing hydration consumption of concrete. and 3, the preparation method ofthe super absorbent resin is simple in process and cost-saving, and has great market promotion value.
本发明提供一种适用于混凝土碱性环境的高吸水树脂及其制备方法，制备方法包括：使配方量的单体溶液、引发剂溶液和交联剂溶液充分搅拌混合均匀，进而使引发剂溶液和交联剂溶液在单体溶液中充分分散，得到混合溶液；对混合溶液进行阶梯升温。优点为：1、本发明的高吸水树脂的制备方法，可在水浴锅中静置聚合，生产设备简单，成本低。2、本发明的高吸水树脂的制备方法制备得到的高吸水树脂，具有卓越的吸水倍率，可作为一种优良的补充混凝土水化消耗的补水剂。3、本发明的高吸水树脂的制备方法工艺简单，节省成本，具有极大的市场推广价值。
