| titleOfInvention | A kind of high efficiency water reducing agent and preparation method thereof |
| abstract | The present invention provides a kind of high efficiency water reducing agent and preparation method thereof, raw material include 40-60 parts of ethylene oxide, 40-60 parts of propylene oxide, 5-10 parts of methallyl alcohol, 5-10 parts of prenol, 20-35 parts of acrylic acid, 20-35 parts of methyl acrylate, 20-35 parts of butyl acrylate, 20-35 parts of methyl methacrylate, dredge 2-4 parts of base ethyl alcohol, 2-4 parts, -4 parts of Catergen of rongalite in parts by weight；Present invention process process is simple, has many advantages, such as that high water resistant, concrete pump transporting resistance be small, bubble-free, and freezing tolerance is strong, convenient for construction；The polyethers I type intermediate of first step preparation and the polyethers II type intermediate of second step preparation, which are stored in material feeding jar, guarantees semi-finished product form convenient for the processing of subsequent workshop section；Thin base ethyl alcohol, rongalite, vitamin C in auxiliary material aqueous solution play the role of being modified as reaction raw materials to product polycarboxylate water-reducer, improve its water-reducing effect and guarantor is collapsed effect. |
