Abstract

The invention discloses a quick-drying caulking agent with stain-resistant function,belongs to the field of caulking agent.The caulking agent is formulated by the following component by weight: 5-20 parts of white portland cement,15-30 parts of aluminate cement,4-10 parts of hemihydrategypsum, 0-2 parts of anhydrite, 0-5 parts of calcium powder, 40-50 parts of quartzsand, 0.5-1 parts of shrinkage reducing agent,0.5-2 parts of water repellent,0.5-3 parts of antifoam agent, 0.5-2 parts of cellulose ether. The invention acceleratesthe condensation of the caulking agent by using of aluminate cement semi-water gypsum ternary quick-drying system,and prevents the leakage of soluble salts to a certain extent, avoids the problem of saltpetering for materials from the source; and the construction period is greatly shorted, the labor costs is reduced;and at the same a dense material layer is formed,the compactness of the material is increased in combined with the role of hydrophobic agent and rubber powder, the invention improves the problems of loosen and porous and not stain-resistant of ordinary cement-based material, the stain-resistant performance of the caulking agent is greatly improved.

Description

technical field [0001] The invention relates to a quick-drying caulking agent with anti-fouling function, which belongs to the field of caulking agents. Background technique [0002] Tile grout, as a supporting grouting material for tile paste, has grown along with the large increase in the area used for tiles. Tile grout has developed from the original white cement to the current mainstream polymer modified cement-based grout. And the beauty joint products that have gradually developed in recent years, including acrylic, polyurethane, and epoxy products. Such beautifying agent products usually have a high cost and are difficult to promote. [0003] At present, the main focus of polymer modified cement-based joint fillers is on the issues of stain resistance, mildew resistance, and pan-alkali resistance, and progress has been slow. The problems encountered by cement-based joint fillers come from two aspects. First, the cement-based materials are loose and porous, and the ...
