The invention relates to the technical field of building materials, and particularly discloses a carbon-based
ceramic tile back
adhesive and a preparation method thereof. The carbon-based
ceramic tile gum is prepared from the following raw materials in parts by weight: 90 to 110 parts of organic
silicon modified
epoxy resin, 10 to 20 parts of
reactive diluent, 25 to 45 parts of composite functional filler, 1 to 3 parts of
coupling agent, 0.5 to 1.5 parts of defoaming agent, 0.3 to 0.8 part of thixotropic agent, 40 to 60 parts of
cardanol modified amine curing agent and 2 to 5 parts of
accelerant, and the composite functional filler is a microcapsule with a core-shell structure. The
organosilicon modified
epoxy resin and the
cardanol modified amine curing agent form a cross-linking
system, the composite functional filler with the core-shell structure is adopted,
phase change is generated to absorb or release
latent heat when the temperature changes, the
temperature gradient in the
adhesive layer is stabilized, and thermal stress accumulation is reduced, so that through the synergistic effect of
phase change energy storage and interface enhancement, the thermal stress performance of the
adhesive layer is improved. Thermal stress damage is effectively buffered, and interface
cracking and hollowing are avoided.
