Abstract：Based on the optimized ratio of polymer-modified cementitious coating emulsion,the effect of organosilicon monomer on the compatibility and impermeability of polymer-modified cementitious coating was investigated through calcium ion stability,sieve residue rate,and Zeta potential.In addition,the mechanism of organosilicon monomer's impact on emulsion stability was elucidated in combination with theological test.The results show that during the modification process of emulsions with organosilicon,molecular chain entanglement flocculation increased,leading to a decrease in Zeta potential.When the dosage of organosilicon is 2％,the polymer-modified cementitious coating exhibits optimal performance,with significantly enhanced anti-corrosion and impermeability properties.Compared to commercially available emulsions,the organosilicone polymer-modified cementitious coating exhits 27.8％,35.1％reduction in water absorption ratio and electrical flux,respectively.
