Abstract：The variation of the properties of tile adhesives with different amounts of emulsion powder and cement in water immersion,freezing and thawing and high temperature conditions was studied,and the influencing factors and improvement techniques of its durability were analyzed in depth. The results show that the bonding strength of 28 d for tile adhesive is mainly related to the content of cement and the content of emulsion powder. When the content of emulsion powder is lower than 1％,the tensile bonding strength is not improved obviously,the water-resistant bonding strength is mainly related to the amount of cement, when the cement content is low,the water resistance decreased,but the dosage of cement should not be too high,that will form a compact surface which decrease the force of mechanical anchor. Meanwhile,the emulsion powder dispersed and had swelling behavior facing with water,so increasing powder content is good for its water resistance property. The freeze-thaw resistance bond strength of tile adhesive require both ability of water resistance and stress deformation,so the powder content should not be too low,the main factors affecting the bond strength of aging resistance of tile adhesive is the emulsion powder content and moisture content of the substrate.
