Ceramic tile adhesive

Abstract

The invention relates to a ceramic tile adhesive. The ceramic tile adhesive is prepared from the following raw materials in parts by weight: 40-45 parts of cement, 40-45 parts of silica sand, 15-20 parts of heavy calcium powder, 3-5 parts of re-dispersible latex powder, and 2-5 parts of an additive; the cement is silicate cement; as for the silica sand, the fineness is 200 meshes or below, the mudcontent is smaller than 0.5% by weight, and the water content is smaller than 0.5% by weight; as for the heavy calcium powder, the fineness is 200 meshes or below, and the water content is smaller than 0.5% by weight; and the additive is a mixture of cellulose ether, lignocellulose and starch ether. The ceramic tile adhesive has the advantages that various organic polymers are added, the bondingstrength is high, the hardening speed is high, and the service life of various ceramic tiles is greatly prolonged; and the ceramic tile adhesive is convenient to construct, and can be used only by adding the right amount of fresh water to be stirred, and the pasted ceramic tiles can be directly pasted without being soaked in water.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a ceramic tile adhesive used for bonding ceramic tiles and facing tiles. Background technique [0002] With the rapid development of the decoration industry, the traditional cement mortar bonded ceramic tiles, due to the poor flow resistance of the mortar, when pasting vertical components such as walls, the tiling must start from the low end, and the tiles need to be used Only the locator can achieve neat jointing. After bonding, the tiles often appear empty, falling off and bonding is not strong, the tiles are bonded and sink, and the problem of uneven bonding, especially for exterior wall decoration, will also bring safety problems. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a ceramic tile adhesive, which improves the bonding strength between the tile and the base material, and ...

[0002] With the rapid development of the decoration industry, the traditional cement mortar bonded ceramic tiles, due to the poor flow resistance of the mortar, when pasting vertical components such as walls, the tiling must start from the low end, and the tiles need to be used Only the locator can achieve neat bonding. The tiles after bonding often appear hollow, falling off and bonding is not strong, the tiles are bonded and sink, and the problem of uneven bonding, especially for exterior wall decoration, will also bring safety problems.
