Workable water reducing agent and preparation method thereof
The invention relates to a workable water reducing agent and a preparation method thereof. The workable water reducing agent is prepared from the following raw materials in parts by weight: 1-5 parts of ethyl cellulose maleate, 70-90 parts of glacial acetic acid, 30-150 parts of polyoxyethylene ether, 0.5-5 parts of a reducing agent, 0.1-0.5 part of an oxidizing agent and 5-20 parts of unsaturated carboxylic acid. According to the workable water reducing agent disclosed by the invention, maleic acid ethyl cellulose is introduced into a molecular side chain of the workable water reducing agent, so the requirements of concrete on flowability, cohesiveness and water-retaining property are met at the same time.
本发明涉及一种和易型减水剂及其制备方法，以重量份数计，和易型减水剂的制备原料包括马来酸乙基纤维素1～5份；份冰醋酸70～90份；聚氧乙烯醚30～150份；还原剂0.5～5份；氧化剂0.1～0.5份；不饱和羧酸5～20份。本发明的和易型减水剂在和易型减水剂的分子侧链引入了马来酸乙基纤维素，同时满足混凝土对流动性、粘聚性和保水性要求。
