Mold-proof and waterproof underground engineering waterproof decorative finish mortar

Abstract

The invention discloses mold-proof and waterproof underground engineering waterproof decorative finish mortar which is prepared from a main material and an auxiliary material. The ratio of the weight percentage of the main material to the weight percentage of the auxiliary material is (95-98):(2-5). The main material is prepared from, by weight, 35-60% of cement and 50-60% of quartz sand. The auxiliary material is prepared from, by weight, 0.4-0.8% of calcium stearate, 1.5-2% of silicon dioxide, 0.01-0.02% of sodium sulfate, 1.5-2% of calcium carbonate, 0.01-0.02% of copper acetate monohydrate, 0.01-0.02% of sodium 2-olefinsulfonate, 1-2% of titanium dioxide and 0.1-0.2% of potassium alum. The decorative finish mortar is mainly used for underground engineering decorative finish and can be directly constructed on a wall base which is not dry, the constructed finish can prevent mold, bubbling, powder falling and water seepage, and the problems that existing finish materials are simplex in function and complex in construction and the finish quality can not reach the requirement are effectively solved.

Description

technical field [0001] The invention relates to a building material, in particular to a mildewproof and waterproof underground engineering waterproof finishing mortar. Background technique [0002] With the expansion and expansion of urban construction, land resources are becoming more and more tense, and engineering activities for the development and utilization of underground space can be seen everywhere. Another example is many caves, tunnels, underground railways, etc., which are indispensable parts of modern construction projects. Many waterproof materials, facing materials and surface protection materials used in the development and construction of these underground projects generally have defects such as single function, complicated construction procedures, high cost, unreliable environmental performance and short service life. + plastering mortar + paint layer finish" design and construction method. There are many construction procedures, the quality of materials i...

AI Technical Summary

Problems solved by technology

[0003] 1. Coatings are chemical mixtures with complex components, and there are volatile substances harmful to the ecological environment. They are not suitable for use in poorly ventilated environments such as basements, and coatings generally accelerate aging, cracking and shelling in about 2 years;

[0004] 2. The poor waterproof performance of the putty determines the low bonding strength between the putty and the wall. It is easy to pulverize and peel when it encounters water vapor erosion. If there is water seepage on the wall or the space is wet, it is easier to crack and peel. Powdered off;

[0006] 4. Unable to solve the problem of water seepage on the wall

[0007] The above situation not only affects the design and use requirements of underground engineering, but also directly affects the health and safety of its living environment.
