Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a mortar for bonding ceramic tiles. Background technique [0002] At present, the bonding material between tiles and the ground or wall is completely mixed with mortar on site. This method is to mix sand, cement and water in a certain proportion on site to make simple cement mortar, and then paint this mortar. On the soaked tiles, then mechanically tap the tiles to ensure that the tiles are on the same level. Due to the poor flow resistance of mortar, when pasting vertical components such as walls, the tiling must start from the low end, and a locator is required between the tiles to achieve neat joints. The proportion of the components of the mortar in this mixing method is difficult Control, uneven viscosity, weak adhesion, prone to hollowing, tile bonding sinking, and uneven bonding. Contents of the invention [0003] In order to solve the above-ment...
