Antibacterial slump retaining agent and preparation method thereof
The invention relates to an antibacterial slump retaining agent and a preparation method thereof; the antibacterial slump retaining agent comprises the following components in parts by weight: 20 to 45 parts of isopentenol polyoxyethylene ether; 5 to 15 parts of esterified chitosan; 20 to 30 parts of deionized water; 1 to 3 parts of a reducing agent; 0.2 to 1 part of ferrous sulfate solution; 2 to 3 parts of an oxidizing agent; 10 to 20 parts of a solution A; and 10 to 20 parts of a solution B. The solution A comprises acrylic acid, deionized water and citric acid, and the solution B comprises a vitamin C aqueous solution or a D-sodium erythorbate aqueous solution. The invention provides an antibacterial slump retaining agent and a preparation method thereof, and solves the problem that the existing polycarboxylic acid slump retaining agent quickly deteriorates when being stored after being compounded with retarders such as sodium gluconate and white sugar under the condition of meeting the requirements of environmental protection.
本发明涉及一种抗菌型保坍剂及其制备方法，以重量分数计，抗菌型保坍剂包括异戊烯醇聚氧乙烯醚20～45份；酯化壳聚糖5～15份；去离子水20～30份；还原剂1～3份；硫酸亚铁溶液0.2～1份；氧化剂2～3份；A液10～20份；以及B液10～20份，所述A液包括丙烯酸、去离子水和柠檬酸；所述B液包括维生素C水溶液或D‑异抗坏血酸钠水溶液。本发明提供一种抗菌型保坍剂及其制备方法，在满足绿色环保的要求下，解决了现有聚羧酸保坍剂在复配葡萄糖酸钠、白糖等缓凝剂后存放时快速变质等问题。
