Abstract
Considering the compatibility of PCE and SAC, the influence of branch length and density on the compatibility of PCE and SAC, and the influence of PCE branch lengths and densities on the influence of SAC performance from the perspective of apparent adsorption amount. Using nanoscale monomer maleic-anhydride (M-A), allyl-polyethylene glycol (A-P), sodium methylpropylene sulfonate (S-M) as monomers, ammonia persulfate (KPA) as the initiator, solution polymerization, orthogonal test design, synthesized a polymer (PR) in thialuminate cement (SAC), and study the influence of various factors (KPA dosage, reaction time, length, and density of PR branch chain on PR performance). The test bear fruits resules showed that the best formula is the polymerization degree of A-P is 48, the molar ratio of the three monomer mass is N (M-A): N (A-P): N (S-M) = 3.0:2.4.0:1.5, KPA is 8.5% of the total molar amount of monomers, the temperature of reaction is 72 °C, and the time of reaction is 6 h.
