Alkali-activated fly ash dry mixed adhesive for ceramic tiles and preparation method thereof

The invention discloses an alkali-activated fly ash dry mixed adhesive for ceramic tiles and a preparation method thereof. The adhesive comprises the following components in parts by weight: 30-50 parts of fly ash, 0-10 parts of cement, 5-10 parts of slag, 50-70 parts of aggregates, 1.2-1.5 parts of redispersible latex powder, 0.03-0.06 part of water-retaining agent, 0.03-0.05 part of wood fibers, 8-15 parts of sodium silicate, 2-3 parts of sodium hydroxide and 0.6-1.0 part of plasticizer. The dry mixed adhesive for ceramic tiles, which is provided by the invention, has the beneficial effects that the problems of hollowing and falling of the ceramic tiles caused by deformation caused due to shrinkage of base materials and other factors can be solved by comprehensively applying the alkali activation principle and the polymer reinforcing and toughening mechanisms; the adhesive has high early strength, thus avoiding the phenomenon of ceramic tile slippage; the adhesive can utilize the fly ash resource in quantit
