The invention discloses a two-component ceramic tile back adhesive and a preparation method thereof, the two-component ceramic tile back adhesive comprises a liquid material component A and a powder material component B. The liquid material component A comprises the following components: 40%-60% of a waterproof emulsion, 15%-35% of an epoxy resin modified polyvinyl alcohol adhesive, 15%-40% of water, 0.2%-0.6% of a defoaming agent and 0.3%-0.6% of a preservative; the powder component B comprises the following components: 2%-6% of special cement, 25%-40% of ordinary cement, 25%-40% of fine sand, 10%-25% of mineral powder, 2%-5% of a strength accelerant, 1%-5% of a water-retaining agent, 0.3%-0.8% of iron oxide black and 0.2%-0.5% of a water reducing agent. According to the preparation method of the back adhesive, the flexible emulsion and the rigid cement mortar are used, the back adhesive has good bonding strength due to the rigidity, the back adhesive can resist certain vibration due to the flexibility, cera
