Epoxy Resin Adhesive

Large porcelain tiles have attracted increased demand owing to their cost-effectiveness and superior esthetics. Here, an epoxy resin adhesive was injected into cement mortar, which was then applied to tiles. The adhesion performance of the tiles was subsequently evaluated in terms of the permeability and drying shrinkage under various curing conditions. The epoxy resin adhesive not only penetrated the tile–mortar and mortar–concrete interfaces, but also directly penetrated the mortar, thus enhancing the mechanical adhesion at each interface. In addition to the mechanical adhesion between the tiles and mortar, the epoxy resin adhesive prevents the degradation of adhesion due to shear stress by minimizing the moisture evaporation and shrinkage of the mortar. Evaluation of the adhesion characteristics under water and freeze–thaw curing conditions revealed the vulnerability of the epoxy resin to moisture; however, adequate adhesion performance was observed when the epoxy resin was air-cured prior to being exposed to harsh environments. Moreover, the injection method did not prolong the construction period, but could potentially reduce it during actual application. Nevertheless, further research on the adhesion performance of tiles with injected epoxy resin adhesive is required to evaluate the long-term durability.

The nano-particle modified epoxy resin adhesive was prepared by adding different types of nanoparticles to the epoxy resin adhesives.The influence of the kinds and amount of nanoparticles on the mechanical properties of epoxy resin adhesive was investigated.The investigation results indicated that the addition of three kinds of nanoparticles including nano-silica,nano-titanium dioxide,nano zinc oxide to epoxy resin adhesive has a significant influence on the mechanical properties of nano-composites.And tensile strength and breaking elongation of nano-composites reached the maximum when the amount of nanoparticle reached 4wt%.In addition,the toughening mechanisms of nano-particles modified epoxy resin adhesives was analysed.
