High-performance polycarboxylate water reducer and preparation method thereof

TLDR: In this paper, a high-performance polycarboxylate water reducer and a preparation method for its use was presented. But the method is not suitable for the case of water reduction.

Abstract: The invention discloses a high-performance polycarboxylate water reducer and a preparation method thereof. The high-performance polycarboxylate water reducer is prepared from the following raw materials: acrylic acid, mercaptoacetic acid, isoamylene alcohol polyoxyethylene ether, hydrogen peroxide, vitamin, white sugar, sodium dodecyl sulfate, solid naphthalene, concentrated sulfuric acid, formaldehyde, caustic soda liquid, polyethylene glycol monoethylether methacrylic ester, calcium lignosulphonate, an ethylene oxide-propylene oxide copolymer, trehalose, shale ash, sodium hydrogen sulfite, polyoxyethylene, aluminum triphosphate, oleic acid diethanolamide, dinonylnaphthalene sulfonic acid, urotropin, an additive, acetone, sodium sulfite, acrylamide, an initiating agent and water. The preparation method comprises the following steps: mixing the isoamylene alcohol polyoxyethylene ether and the like; after the solid naphthalene is processed, adding a silicone powder into the processed solid naphthalene and stirring the mixture; processing the acrylamide and the like; finally, mixing products obtained in the former three steps, so as to obtain the high-performance polycarboxylate water reducer. The high-performance polycarboxylate water reducer has the advantages that the corrosion resistance and the water reducing rate can be improved, and the slump loss is smaller.
