Special function back water pressure anti-seepage waterproof mortar coating

Abstract

The invention discloses a special function back water pressure anti-seepage waterproof mortar coating. The special function back water pressure anti-seepage waterproof mortar coating is prepared fromthe following raw materials: special cement, dispersible mildew-proof sterilizing adhesive powder, a calcium sulphate retarder, a defoaming agent, calcined gypsum, lime, quartz sand, a concrete waterreducing agent, a cement expansive agent, cellulose and an anti-mildew sterilizing agent. The special function back water pressure anti-seepage waterproof mortar coating disclosed by the invention does not need batch scraping for mortar, is good in waterproof, moisture-proof, leakproof, waterproof effects and does not age for at least 10 years and is resistant to acid and alkali; in addition, water seepage can be completely avoided and prevented, and various problems of blooming, salt-alkali walls, mildew to produce algae, wall body pulverization and the like are solved; the special function back water pressure anti-seepage waterproof mortar has an excellent market prospect.

Description

technical field [0001] The invention belongs to the technical field of coating materials, and more specifically, the invention relates to special functional back water pressure anti-seepage and waterproof mortar coatings. Background technique [0002] Many buildings have waterproof and anti-seepage requirements, but ordinary concrete cement has poor anti-seepage and waterproof performance, and water can penetrate through the micropores of concrete cement. Therefore, during construction, waterproof coils, coatings and other materials are often used to isolate the water source on the front or back surface of ordinary concrete. This kind of construction process is relatively complicated, and the waterproof effect cannot be guaranteed. There is also a rigid internal waterproof structure, but its crack resistance is poor, and it cannot cure all the pores and cracks of the porous structure. The waterproof effect is poor and the waterproof cost is high. There is also the use of ce...

Problems solved by technology

[0002] Many buildings have waterproof and anti-seepage requirements, but ordinary concrete cement has poor anti-seepage and waterproof performance, and water can penetrate through the micropores of concrete cement

Therefore, during construction, waterproof coils, coatings and other materials are often used to isolate the water source on the front or back surface of ordinary concrete. This kind of construction process is relatively complicated, and the waterproof effect cannot be guaranteed.

There is also a rigid internal waterproof structure, but its crack resistance is poor, and it cannot cure all pores and cracks in the porous structure. The waterproof effect is poor and the waterproof cost is high.

There is also the use of cement-based permeable crystalline waterproof coatings, which can not only ensure waterproof performance, but also reduce waterproof costs. However, most of them are mixed with water and painted on the surface of concrete to fill cracks on the concrete surface. quite difficult

In addition, the existing paint does not have the effect of antibacterial and antifungal
