Preparation method of high-performance concrete water reducing agent
The invention provides a preparation method of a high-performance concrete water reducing agent. The preparation method comprises the steps of firstly, adding methyl allyl polyethenoxy ether, maleic anhydride and sodium methylacrylsulfonate into a reaction kettle, stirring by heating, dropwise adding propenoic acid, stirring by preserving the heat to obtain a mixture A; then, mixing n-octyl acrylate, styrene, hydroxypropyl acrylate, trimethylolpropane triacrylate and azobisisobutyronitrile to obtain a mixture B; and finally, adding the mixture B into the mixture A, then, adding triethanolamine and sodium thiocyanate, and stirring to obtain the high-performance concrete water reducing agent. The preparation method of the high-performance concrete water reducing agent, provided by the invention, is simple in production technology and convenient to operate; and the obtained water reducing agent not only has relatively high water reducing rate, but also has relatively high compressive strength.
