The problem of ceramic tile falling is always the pain point of the tiles in China, and no complete tile system exists. The ceramic tile adhesive is widely applied abroad, and a matched tile system is complete; in China, the tile adhesive is still in the primary stage of development, the paving technology and the paving system have the problems of base surface flatness due to material limitation, and the construction process is not effectively popularized.

Most of the ceramic tile interface treating agents appearing on the market are treating agents of a pressure-sensitive adhesive system, are applied to a tile system, are difficult to meet the national building material industry standard JC/T547-2017 ceramic tile adhesive (international universal standard requirement), require the tensile bonding strength of the tile system, the tensile bonding strength after soaking, the tensile bonding strength after thermal aging, the tensile bonding strength after freeze-thaw cycle, the tensile bonding strength after airing for 20 minutes are not less than 0.5 MPa, particularly the tensile bonding strength after soaking, and the ceramic tile interface treating agents of the pressure-sensitive adhesive system can not reach far; in addition, the environmental protection index of the interface treating agent on the market is difficult to meet the standard requirement of the adhesive of the technical requirement of the national environmental protection standard HJ2541-2016 environmental marking product.
