Preparation of mud-resistant concrete admixture
The invention belongs to the technical field of concrete, and particularly relates to preparation of a mud-resistant concrete admixture, which comprises a preparation method comprising the following specific steps: mixing 8-10 parts of isobutenol polyoxyethylene ether, 2-4 parts of mercaptopropionic acid, 8-12 parts of acrylic acid and 20-30 parts of water in a reaction kettle; 6-10 parts of polyepichlorohydrin dimethylamine and the mixture obtained in the first step are placed in a reaction kettle to be mixed; by adding the polyepichlorohydrin-dimethylamine, the weather resistance, corrosion resistance, heat resistance, aging resistance, toughness, hardness, anti-swelling performance and shear resistance of the concrete can be improved, so that the performance of the concrete can be improved only by adding the polyepichlorohydrin-dimethylamine; and the cost investment is reduced to a certain extent.
本发明公开的属于混凝土技术领域，具体为一种抗泥型混凝土外加剂制备，包括一种制备方法，具体步骤如下：将异丁烯醇聚氧乙烯醚8份‑10份、巯基丙酸2份‑4份、丙烯酸8份‑12份和水20份‑30份置于反应釜中进行混合；将聚环氧氯丙烷二甲胺6份‑10份和步骤一中所得到的混合物置于反应釜中进行混合；本发明通过添加聚环氧氯丙烷二甲胺具有能够提高混凝土的耐候性能、耐腐蚀性能、耐热性能、耐老化性能、强韧性能、硬度性能、防膨性能和耐剪切性能，进而能够实现只需添加聚环氧氯丙烷二甲胺即可提高混凝土的性能，在一定程度上降低了成本的投入。
