Liquid segregation repairing agent and preparation method thereof
The invention discloses a liquid segregation repairing agent and a preparation method thereof. The liquid segregation repairing agent is prepared from, by weight, 13-16 parts of cyclic unsaturated acid, 2-6 parts of unsaturated amide, 0.8-1.5 parts of an initiator, 1-2 parts of a chain transfer agent, 10-15 parts of a pH regulator and 55.5-71.2 parts of water, wherein the molecular weight of the liquid segregation repairing agent ranges from 40000 to 80000. When the liquid segregation repairing agent is added into concrete, the workability of the concrete can be improved, meanwhile, it can be guaranteed that the slump/expansion degree of the concrete is not reduced, the setting time of the concrete is not prolonged, and the strength of the concrete is not reduced.
本申请公开一种液体离析修复剂及其制备方法，液体离析修复剂按重量份数计包括13～16份的环状不饱和酸、2～6份的不饱和酰胺、0.8～1.5份的引发剂、1～2份的链转移剂、10～15份的pH调节剂及55.5～71.2份的水，液体离析修复剂的分子量为40000～80000之间，本申请的液体离析修复剂加入混凝土中，能够在改善混凝土的和易性的同时，还能够同时保证混凝土坍落度/扩展度无损失、混凝土凝结时间未延长及混凝土强度未降低。
