Polycarboxylate water reducing agent and preparation method thereof
The invention discloses a polycarboxylate water reducing agent and a preparation method thereof. The water reducing agent is prepared from the following main components in parts by weight: methyl allyl polyethenoxy ether, sodium methallyl sulfonate, maleic anhydride, acrylamide, propenoic acid, hydrogen peroxide, mercaptoacetic acid and purified water. The polycarboxylate water reducing agent has the advantages that the water reducing rate reaches up to 45%, the high water reducing and slump loss resisting requirements of concrete can be better met, the sensitivity to temperature is low, the adaptability to cement is strong, the preparation process is simple, and the preparation is easy.
