PURPOSE: An inorganic material-based coating composition for protecting the concrete external wall is provided, which is improved in the antibacterial effect, the weather resistance, the adhesion, the wearing resistance, the water proofness, the air permeability and the peeling-off resistance. CONSTITUTION: The coating composition comprises: 10-50 wt% of an inorganic adhesive curing agent selected from white cement, common cement such as 1,2,3,4,5 kind cement, alumina cement, other special cements and their mixtures; 10-70 wt% of a filling-reinforcing agent selected from calcium carbonate, talc and their mixture; 1-20 wt% of a synthetic resin adhesive selected from acryl powder, water-soluble acryl silicon, water-soluble acryl urethane, water-soluble acryl epoxy and their mixtures; 1-30 wt% of a strength-reinforcing agent selected from calcium hydroxide, silica hume, furnace slag, fly ash, gypsum and their mixtures; 0.1-5 wt% of a crack-preventing agent selected from wood meal fiber, synthetic non-woven fiber, natural non-woven fiber and their mixtures; 0.01-5 wt% of water-insoluble antibacterial agent selected from water-insoluble silicate fluoride, metal-coated titanium dioxide, polyhalogenated phenol, sodium benzoate, benzalkonium chloride, copper compound, chemical dieldrin and their mixtures; 0.1-5 wt% of a water permeation-preventing agent selected from a metal salt of high molecular fatty acid, silane powder, siloxane and their mixtures; 0.001-3 wt% of a moisture-increasing agent selected from ethyl or methyl substituted cellulose, carboxy methylcellulose, cellulose ether, bentonite and their mixtures; and 0.001-3 wt% of a surfactant selected from lignin sulfonate, naphthalene sulfonate, melamine sulfonate, poly(carbonic acid), biopoly, tartaric acid, casein and their mixtures. |
