Concrete conditioning agent and preparation method and application thereof
The invention discloses a concrete conditioning agent as well as a preparation method and application thereof, and the conditioning agent has a structure as shown in a formula (1) or a formula (2): wherein R1, R2, R3 and R5 are the same or different and are independently selected from H and C1-6 alkyl, R4 is selected from a C1-C9 alkylene group; R6 is H or a C1-8 alkylene alcohol; 0 < a < = 180, 0< = b < = 10; 0 < c < = 10; and 0 < d < = 200. According to the concrete conditioning agent provided by the invention, the conditioning agent with a water retention function is obtained by polymerizing polyether monomer containing different block oxides and acrylic monomer, the water solubility is high, the conditioning agent can be mutually dissolved with water and polycarboxylic acid mother liquor in any proportion, and the concrete workability is better.
本发明公开一种混凝土调节剂及其制备方法和应用，所述调节剂具有如式(1)或式(2)所示的结构：其中，R1、R2、R3、R5相同或不同，彼此独立地选自H、C1‑6烷基；R4选自C1‑C9亚烷基；R6为H或C1‑8亚烷基醇；0＜a≤180，0≤b≤10；0＜c≤10；0＜d≤200。本发明提供的混凝土调节剂以含有不同嵌段含氧化物的聚醚单体和丙烯酸类单体聚合，得到具有保水功能的调节剂，水溶性好，可以与水及聚羧酸母液以任意比例互溶，混凝土和易性好更好。
