Polycarboxylic acid water reducing agent containing maleic anhydride and preparation method thereof
The invention discloses a polycarboxylic acid water reducing agent containing maleic anhydride and a preparation method thereof, and solves the technical problems of poor workability and poor adaptability when a water reducing agent is doped into machine-made sand (poor materials) in the prior art. The polycarboxylic acid water reducing agent is prepared from the following raw materials in parts by weight: 340-380 parts of isoamyl alcohol ether, 360-400 parts of water, 9-30 parts of maleic anhydride, 4-6 parts of acrylamide, 7-22 parts of acrylic acid, 4-7 parts of hydrogen peroxide, 1-3 parts of a chain transfer agent and 1-3 parts of a reducing agent. The water-reducing rate of the polycarboxylic acid water reducing agent containing maleic anhydride is 33% or above, and the workability and adaptability are excellent.
本发明公开了一种含马来酸酐的聚羧酸减水剂及制备方法，解决了现有技术中的减水剂掺入机制砂（较差材料时）中时会出现和易性差，适应性差的技术问题。所述聚羧酸减水剂制备包括下述重量份的原料：异戊烯醇醚340～380份，水360～400份，马来酸酐9～30份，丙烯酰胺4～6份，丙烯酸7～22份，双氧水4～7份，链转移剂1～3份，还原剂1～3份。本发明中的含马来酸酐聚羧酸减水剂的减水率在33%以上，和易性和适应性均表现优异。
