Problems solved by technology

In CN108676522A, the single-component liquid material back glue speeds up the initial drying speed, but adding sand, the amount of back glue per unit area increases significantly, and the cost per unit area is higher
In CN104529342A, the next process can be carried out after 5 hours of back glue construction, and in CN108117342A, the next process can be carried out after 3 hours of back glue construction. Agglomeration is easy to occur, and the batch stability of sulphoaluminate cement is poor. Each batch needs to be adjusted according to the actual performance of sulphoaluminate cement. The production process is not particularly convenient.
It is introduced in CN105777009B that the construction of the back glue can be carried out after 30-40 minutes in the air, but the amount of methyl hydroxypropyl cellulose ether is used more, and the surface of the back glue is still wet after 30-40 minutes of construction. There is a phenomenon that most of the back glue on the back of the vitrified tile is taken away by the adhesive, and special attention needs to be paid to the back glue in order to keep it, and the construction efficiency is not high

Abstract

The invention belongs to the technical field of brick gum, and discloses quick-drying high-flexibility vitrified brick gum and a preparation method thereof. The vitrified brick gum comprises a liquid material component and a powder material component. On the basis of the total weight of the powder material component, the powder material component comprises the following components by weight: superfine Portland cement, aggregate, a water-retention thickening agent, an early strength agent and light calcium carbonate; and on the basis of the total weight of the liquid material component, the liquid material component comprises the following components by weight: styrene-butadiene latex, a mildew preventive, a defoaming agent, a sterilizing agent and water. The water-retention thickening agent is a mixture of a cellulose ether compound, xanthan gum and sepiolite. After being brushed, the gum can be quickly formed into a film and dried, so that the construction efficiency is improved, the bonding strength is ensured, and the gum has good flexibility.

Description

technical field [0001] The invention belongs to the technical field of brick back glue, and in particular relates to a quick-drying highly flexible vitrified brick back glue and a preparation method thereof. Background technique [0002] Vitrified tiles, as the tiles with the lowest water absorption rate among tiles, are more and more used in the construction field. In recent years, in order to further improve the aesthetics of buildings, vitrified tiles are not only used on the ground, but also on the wall. In the early stage of use, workers generally use polymer modified tile adhesive to paste vitrified tiles. Combined with the poor flatness and verticality of the building base, the thickness of tile adhesive generally reaches more than 10mm, and in some cases it reaches more than 30mm. If the polymer modified tile adhesive adopts the thin-layer construction method, the thickness of the tile adhesive is 2-5mm, which can achieve the firm effect of pasting vitrified tiles. ...
