Abstract

The invention relates to a water-retaining agent and a preparation method thereof, tile adhesive and a preparation method thereof. Belonging to the technical field of building materials, in parts by weight, the water retaining agent includes: 4-7 parts of active agent; 24-70 parts of hyaluronic acid; 45-200 parts of alcohol; 40-100 parts of water; Fatty alcohol ethoxylate sulfates and / or alkylbenzene sulfonates. The water retaining agent has good water retention effect, long airing time and good moisture absorption effect. When preparing tile adhesives, adding a very small amount of the water-retaining agent of the present invention can significantly prolong the airing time, increase the adjustable time of tile laying, and solve the problem of poor adhesion of tiles due to insufficient airing time. Problem with hollow tiles. Moreover, it can enhance the degree of hydration reaction of the tile adhesive without affecting the setting time, which is beneficial to the improvement of the strength in the later stage.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a water-retaining agent, a tile glue and a preparation method thereof. Background technique [0002] Tiles are one of the commonly used decorative materials for walls and floors in the construction industry. At present, tile adhesives are widely used as adhesives for pasting tiles. The largest amount of tile adhesives on the market is cement-based dry powder products with admixtures such as dispersible latex powder. The manual construction process of laying tiles with tile glue includes plastering and scraping teeth on the wall and floor, scraping the back of the tiles, and then laying tiles. However, in the process of laying tiles, in order to improve the efficiency of laying, the general construction personnel will apply the slurry on a large area before laying the tiles. The high water absorption will cause the tile adhesive to lose water, and the hydration in the ...
