A kind of ceramic tile adhesive and its application

Abstract

The invention discloses a tile binder. The binder comprises the following components in percentage by mass: 15%-30% of aqueous polymer resin, 65%-85% of filler, 10%-20% of photocatalysis catalyzer, 0.2%-0.4% of thickener, 0.2%-0.3% of water repellent, 0.2%-0.3% of defoamer, 0.4%-0.6% of corrosion remover, 0.1%-0.3% of wetting dispersant, 0.2-0.5% of thixotropic agent, 0.5%-1.0% of storage stabilizer, 1.0%-1.5% of brightener, 0-5% of mill base and the balance of water. According to the binder, the saltpetering problem caused by overhigh alkalinity is solved, and corrosion to mosaic and other glass materials caused by alkaline components in the binder is avoided; meanwhile, the compactness and brightness of the binder are improved, and the binder has stain resistance; the selected raw materials are non-toxic and harmless, is an environment-friendly product, and has great promotion value.

Description

technical field [0001] The invention belongs to the technical field of construction chemical materials, and in particular relates to a ceramic tile adhesive, which has the characteristics of neutrality, water resistance, easy wiping, environmental protection and no pollution. Background technique [0002] With the development of the ceramic industry, ceramic tiles are more and more favored by consumers as building decoration materials. At the same time, it is more and more widely used as a high-grade mosaic with excellent decoration. When ceramic tiles or mosaics are used for interior decoration, it is necessary to use an adhesive to achieve a close fit with the surface of the building body. For this reason, in addition to requiring good bonding strength, the adhesive also requires a good match between the adhesive and the tile or mosaic, that is, the composition of the adhesive cannot affect the tile material; in addition, due to the usual It is necessary to repair the ga...

Problems solved by technology

Cement-based adhesives and caulks have high alkalinity, and they are prone to pan-alkali phenomenon after long-term use, and color deposition will occur on the surface of the tiles or in the gaps, which greatly affects the aesthetics of the decoration. More importantly, when the decoration When the surface is made of glass materials such as mosaics, the strong alkali components in the cement-based adhesive will have a serious corrosion effect on the surface of the mosaic, making it lose its decorative effect and even cause the phenomenon of surface detachment; while epoxy resin adhesives Although it will not cause efflorescence or the peeling off of the glass decorative surface, the process steps of its use and production are relatively cumbersome, and the material cost is high. What is more serious is that the epoxy resin adhesive contains toxic components and is not environmentally friendly. material requirements, thus limiting its application in markets

For the sealant exposed on the surface of the building, it is necessary to clean the pollutants after a long period of use. It is difficult for the sealants of the above two materials to achieve the cleaning function; if inorganic gelling materials are used, such as silicon Salt cement, aluminate cement and other high-alkaline material binders, although beneficial to cleaning, will lead to a decrease in the bonding performance of tiles

However, if a neutral gelling material, such as gypsum minerals of different crystal forms, is used as a binder or a caulking agent, due to its poor water resistance, it is easy to dissolve in a humid environment and destroy the bonding effect.
