Abstract：In order to solve the problem that the back surface coating is prone to alkali hollowing and cracking with the foundation cracking,four kinds of polymer lotion styrene acrylate copolymer lotion(SA),ethylene vinyl acetate copolymer lotion(VAE),water-borne epoxy lotion(EP)and chloroprene lotion(CRL)with different contents are added into the existing inorganic waterproof and plugging materials to form lotion modified inorganic waterproof and plugging materials and their performance is test-ed.The results show that the addition of lotion can improve the fluidity and retard the setting,and the effect is more obvious with the increase of lotion content.At the same time,the addition of lotion will reduce the compressive strength,improve the bending strength,tensile strength,bonding strength and impermeability strength,and reduce the shrinkage rate.Among them,the SA content of 15%has the best effect on improving the impermeability performance.The best effect is to increase the tensile bonding strength with an EP dosage of 10%,and to reduce the shrinkage rate with 15%.The best effect is to increase the flexural strength with a VAE content of 15%,and the best effect is to increase the tensile strength with a VAE content of 10%.
