Problems solved by technology

[0003] At present, the main methods to improve the pan-alkaline resistance of cement-based materials include adding metakaolin and other volcanic ash raw materials to react with calcium hydroxide in the material, and waterproofing the surface of the material to reduce water transmission. These methods have the disadvantages of high cost and complicated process.

Abstract

The invention discloses an saltpetering-resistant ceramic tile adhesive which is prepared from aggregate and powder. The powder comprises cement, mineral powder, active silicon dioxide, cellulose ether, latex powder, a water reducing agent, sodium bicarbonate and the like. The invention also provides a preparation method of the ceramic tile adhesive. According to the saltpetering-resistant ceramic tile adhesive disclosed by the invention, different saltpetering-resistant substances are reserved to play a long-timesaltpetering-resistant role through the use change characteristics of the ceramic tile adhesive, various means and different saltpetering-resistant mechanisms. The saltpetering-resistant ceramic tile adhesive can inhibit the saltpetering degree value of the ceramic tile adhesive, the surface is not obviously whitened after multiple times of soaking circulation, the long-time attractive appearance of the surface is effectively ensured, and the saltpetering-resistant ceramic tile adhesive formula improves various performance index values while effectively inhibiting the saltpetering of the ceramic tile adhesive, and has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a pan-alkaline-resistant tile adhesive and a preparation method thereof. Background technique [0002] After a period of construction of tile facing external wall insulation project, white precipitates often appear in the joints of bricks, that is, pan-alkali phenomenon. Pan-alkali is usually calcium hydroxide in the capillary pores after hydration of calcium silicate in Portland cement. Penetrates to the surface under pressure and forms insoluble white precipitated calcium carbonate crystals with carbon dioxide in the air. Erythrine not only affects the appearance of the building, but also is not conducive to the long-term stability of the external wall system. At present, some disposal methods can only temporarily remove the white precipitate, and it often reappears after a period of time. Therefore, the best way is to prevent pan-alkali. [0003] At present, the m...
