Anti-freezing concrete water reducing agent and preparation method thereof
The invention relates to the field of concrete additives, and particularly discloses an anti-freezing concrete water reducing agent and a preparation method thereof. The water reducing agent is prepared from A: 1-5 parts of ethylcellulose coated bisulfate, 1-3 parts of dispersing agent, 20-40 parts of polycarboxylate water reducing agent, 1-4 parts of sodium gluconate and 50-80 parts of water; and B: 5-10 parts of an alcohol dissolving and releasing agent. The preparation method of the water reducing agent comprises the following steps: weighing the polycarboxylate water reducing agent, sodium gluconate and water, and uniformly mixing the components to obtain a mixture 1; mixing the ethyl cellulose coated bisulfate with the mixture 1, and performing full stirring to obtain A; and weighing the alcohol dissolving and releasing agent to obtain B. The water reducing agent disclosed by the invention can be used for preventing concrete from freezing, so that the working time of constructors is prolonged; and in addition, according to the preparation method disclosed by the invention, the ethylcellulose coated bisulfate is uniformly dispersed, so that solid aggregation is avoided.
本申请涉及混凝土添加剂的领域，具体公开了一种防冻型混凝土减水剂及其制备方法，该减水剂包括A：乙基纤维素包覆硫酸氢盐1~5份、分散剂1~3份、聚羧酸减水剂20~40份、葡萄糖酸钠1~4份、水50~80份；B：醇类溶解释放剂5~10份。减水剂的制备方法为：称取聚羧酸减水剂、葡萄糖酸钠和水，混合均匀，得到混合物1；将乙基纤维素包覆硫酸氢盐与混合物1混合，充分搅拌得到A；称取醇类溶解释放剂，得到B。本申请的减水剂可用于混凝土防冻，延长了施工人员的工作时间；另外，本申请的制备方法使得乙基纤维素包覆硫酸氢盐分散均匀，避免了固体聚集成团。
