Pyridinium cationic compound, pyridinium cationic polymer as well as preparation method and application of pyridinium cationic compound and pyridinium cationic polymer
The invention belongs to the field of polymers, and particularly relates to a pyridinium cationic compound, a pyridinium cationic polymer and a preparation method and application of the pyridinium cationic compound and the pyridinium cationic polymer. Wherein the structural formula of the compound is as shown in formula (1), # imgabs0 # formula (1); wherein n is an integer from 1 to 4, R1 comprises (CH2) mCH3, m is an integer from 0 to 5, and X is Br or I. The pyridinium cationic polymer prepared from the pyridinium cationic compound comprises a hydroxyl group, an ester group and an ether bond, can form a hydration membrane with water, and has relatively strong intercalation adsorption capacity with clay; the catalyst also comprises pyridinium cations with large steric hindrance, and has relatively strong electrostatic adsorption capacity with clay; the pyridinium cationic polymer is used as a sacrificial agent, can effectively adsorb clay and shield the interaction between the clay and the polycarboxylate water reducing agent, and improves the water reducing rate and resistance of the water reducing agent or reduces the dosage of the water reducing agent.
本发明属于聚合物领域，具体涉及一种吡啶鎓阳离子化合物、吡啶鎓阳离子聚合物及其制备方法与应用。其中所述化合物的结构式如式（1）所示，#imgabs0#式（1）；其中，n为1‑4的整数，R1包括(CH2)mCH3，m为0‑5的整数，X为Br或I。由吡啶鎓阳离子化合物制得的吡啶鎓阳离子聚合物中包括羟基、酯基和醚键，能够与水形成水化膜，具有较强的与粘土进行插层吸附的能力；还包括大位阻的吡啶鎓阳离子，具有较强的与粘土进行静电吸附的能力；吡啶鎓阳离子聚合物作为牺牲剂使用，能够有效吸附粘土并屏蔽粘土与聚羧酸酯类减水剂的相互作用，提高减水剂的减水率和耐抗性或降低减水剂的用量。
