Abstract

The invention discloses antibacterial mildew-proof high-strength whitewash mortar, which comprises the following components: silicate black cement, flyash, blast furnace slag, building gypsum, quartz sand, a nano antibacterial mildew preventive, a regulator, an inorganic gel, a retarder, an anti-cracking agent and re-dispersible gelatine powder. The nano antibacterial mildew preventive is nano zinc oxide with the fineness of 30nm; the regulator is hydroxypropyl methyl cellulose; the inorganic gel is sodium bentonite; the retarder is a retarder special for polyphosphate gypsum; the anti-cracking agent is lignocellulose; and the re-dispersible gelatine powder is polyvinyl acetate or ethylene resin. The mildew-proof whitewash mortar prepared according to the formula has the advantages of good mildew resistance and water resistance and extremely strong bonding strength; and after the whitewash mortar is prepared into plastering mortar, the brushed base plane has the advantages of no hollowness, no crack, excellent mildew-proof performance, strong adhesive property, high breaking strength and compression strength, and convenient construction simultaneously.

Description

technical field [0001] The invention relates to an antibacterial and mildew-proof high-strength plaster mortar. Background technique [0002] The decoration materials for building decorations contain the nutrients needed for the reproduction of microorganisms. Therefore, as long as the temperature and humidity conditions are suitable on the building decorations, it will lead to the growth and reproduction of microorganisms and produce mildew, which will erode and damage the decorations. Affects the aesthetics and use of buildings. At present, most of the base products on the market are simply compounded with white cement mixed with glue and cooked rubber powder. Such products are prone to mold growth in high-temperature and high-humidity environments. Chinese invention patent CN02133296.7 disclosed a kind of interior wall anti-mildew and water-resistant large white powder on March 26, 2003, and Chinese invention patent CN97108239.1 disclosed a kind of wall surface anti-mild...
