Description
Technical Field
The invention belongs to the technical field of chemical building materials, and particularly relates to a tile glue adhesive prepared by utilizing recycled slag.
Background
Ceramic tiles are covering materials commonly used for walls or floors in the field of building materials, and are widely used for decoration of walls inside or outside buildings. Along with the improvement of living standard, the requirement of people on the appearance aesthetic feeling of buildings is higher and higher, and the ceramic tile is one of the first choice for improving the appearance aesthetic feeling of buildings, so the requirement of the ceramic tile is increased year by year. When the ceramic tile is used for covering the surface of a building, a special ceramic tile adhesive is needed for pasting the ceramic tile, and mortar used in the prior art cannot meet the requirements of a complex and strict ceramic tile pasting process, for example, (1) the adhesive force can only prevent the ceramic tile from falling off from the coating surface, but cannot prevent the ceramic tile from falling downwards due to self gravity, so that the ceramic tile can only be gradually pasted from bottom to top in construction, and is supported by the ceramic tile which is going downwards. (2) When large stones or polished tiles are adhered, mechanical fixation is needed for additional reinforcement. (3) Because the adhesive strength and the flexibility of the mortar are poor, the mortar on the back of the tile is coated unevenly, so that hollowing appears under the tile, water is easy to accumulate in a cavity, and the tile is easy to crack due to expansion caused by heat and contraction caused by cold during climate change, so that safety worry exists.
Therefore, the use of the conventional mortar causes low pasting efficiency, large material usage amount, and depends on the well-done skill and responsibility of workers. Although there are many special tile glue adhesives on the market to replace the traditional mortar, there still exist a considerable number of products whose quality can not be verified by the inspection standard JC/T547, and in addition, sand is the fine aggregate occupying the largest specific weight in the tile glue adhesives, most of the products on the market still use natural river sand as the fine aggregate, and the natural river sand resource is nearly exhausted under the mass exploitation in recent years, so there is a need to develop a tile glue adhesive which contains environmental protection material to reduce the overuse of natural resources and can meet the inspection standard JC/T547.
