Inorganic single-component polymer ceramic tile gum and preparation method thereof

Abstract

The invention relates to an inorganic single-component polymer ceramic tile back adhesive and a preparation method thereof, and the inorganic single-component polymer ceramic tile back adhesive is mainly prepared from the following components in parts by weight: 34.0-38.0 parts of special cement, 20.0-22.0 parts of anhydrous gypsum, 10.0-14.0 parts of mineral powder, 12.0-20.0 parts of calcium carbonate, 12.0-14.0 parts of redispersible adhesive powder, 0.1-0.3 part of a water reducing agent, 0.2-0.3 part of a defoaming agent, 0.2-0.3 part of cellulose ether, 0.02-0.04 part of an early strength agent, and 0.08-0.10 part of a retarder, wherein calcium carbonate is 180-220-mesh calcium carbonate. According to the inorganic single-component polymer ceramic tile back adhesive and the preparation method thereof, the defects that an existing single-component ceramic tile back adhesive is only suitable for low-water-absorption ceramic tiles and high in cost are overcome, the inorganic single-component polymer ceramic tile back adhesive is prepared on the basis of special cement by adding the anhydrous gypsum and the redispersible adhesive powder according to a preferable dosage ratio and matching with other preferable fillers and additive. The ceramic tile back adhesive has the characteristics of high early strength development speed, high early strength and the like, is short in curing time, can effectively save time cost, is suitable for being matched with various ceramic tiles with low water absorption and high water absorption, is excellent in performance and relatively low in price, and ensures the quality.

Description

technical field [0001] The invention relates to an inorganic single-component polymer tile back glue and a preparation method thereof, which are applied in the field of tile back glue production. Background technique [0002] Most of the tile adhesives on the market today are composed of high-quality polymer emulsion materials. This type of tile adhesive is mostly used in vitrified tiles with low water absorption (water absorption ≤ 0.5%), antique bricks, cultural stones, polished tiles, artificial stone, natural marble, tiles, etc., and is not suitable for some high water absorption (water absorption > 10%) ceramic tiles, such as ceramic tiles, stoneware tiles, square tiles, industrial tiles, etc. And the price of this kind of tile adhesive is expensive. Therefore, it has become an urgent task to provide a low-cost inorganic one-component polymer tile adhesive suitable for high water absorption ceramic tiles and a preparation method thereof.
