The invention discloses a ceramic tile bonding mortar. The ceramic tile bonding mortar is composed of a base material and an additive; the base material comprises, by weight, 350 to 410 parts of ordinary portland cement, 530 to 600 parts of sand with a particle size of 40 to 100 meshes, and 45 to 5 parts of heavy calcium carbonate powder; and the additive comprises, 2 to 3 parts of high-molecular xanthan gum powder, 1.5 to 2 parts of hydroxypropyl methyl cellulose, and 0 to 5 parts of redispersible latex powder. According to the ceramic tile bonding mortar, adding of high-molecular xanthan gum powder and hydroxypropyl methyl cellulose is capable of increasing viscosity of the ceramic tile bonding mortar greatly; water holding effect is excellent; delayed coagulation is realized; operation time of operators is prolonged; the ceramic tile bonding mortar is suitable for long-distance transportation; strength after hardening is high; ceramic tile loosening or falling after bonding is avoided; adding of redispersible latex powder is capable of improving water resistance of the ceramic tile bonding mortar; and construction under moisture circumstances can be carried out.
