Polycarboxylate water reducing agent and preparation method thereof
The invention relates to a polycarboxylate water reducing agent. The structure comprises a structure unit A, a structure unit B and a structure unit C. In the synthesis process of the polycarboxylatewater reducing agent, an ethyl acrylate small monomer is added, and the synthesized water reducing agent can be mutually dissolved with the defoaming agent and is not obviously layered after being placed for a long time through the design of the molecular chain structure so that the stability of the polycarboxylic acid water reducing agent compounded with the defoaming agent is improved, the appearance of concrete is more attractive and firmer, the pore structure and the compactness of the concrete can be improved, and the strength and the quality of the concrete are improved.
本发明涉及一种聚羧酸减水剂，包括以下结构单元A、结构单元B和结构单元C，所述聚羧酸减水剂在合成过程中加入了丙烯酸乙酯小单体，通过分子链结构设计，使合成出的减水剂能与消泡剂互溶，长时间放置无明显分层，提高了复配消泡剂的聚羧酸减水剂的稳定性，让混凝土的外观更加美观和坚固，并能改善了混凝土孔结构和密实程度，提高混凝土的强度和质量。
