Eco-friendly hybrid surface protection coating composition for water-treated concrete structures exposed to high-humidity environment and surface protection construction method for concrete structures exposed to high-humidity environment using the same

摘要

The present invention comprises 1 to 50% by weight of a functional inorganic filler and 50 to 99% by weight of a functional admixture; The functional inorganic filler is 100 parts by weight of ultrafine silicate, 30 to 50 parts by weight of potassium magnesium titanate, 30 to 50 parts by weight of calcium carbonate, 10 to 30 parts by weight of arganite, 10 to 30 parts by weight of zeolite, zinc phosphate (Zn 3 (PO 4 ) 2 ) 1 to 10 parts by weight and 1 to 10 parts by weight of magnesium-amino clay; The functional admixture includes 100 parts by weight of an eco-friendly water-based acrylic emulsion, 10 to 30 parts by weight of a styrene-acrylic acid ester copolymer, 10 to 30 parts by weight of a vinyl acetate-ethylene copolymer, and 1 to 10 parts by weight of a methylhydrogenpolysiloxane represented by the following Chemical Formula 1 parts, by using 1 to 10 parts by weight of hydroxy propyl methylcellulose, 0.1 to 5 parts by weight of tropolone, and 0.1 to 5 parts by weight of a pigment; Excellent waterproof, water resistance, chemical resistance, acid resistance, durability, salt damage resistance, neutralization resistance, stain resistance, weather resistance, UV resistance, non-combustibility and strength, etc. can be realized It provides stable water quality management and is environmentally friendly without releasing harmful substances, so it is exposed to highly wet environments such as water purification plants, drainage plants, structures under dams, sewage treatment plants, water intake plants, water wells, admixtures, flocculation ponds, sedimentation ponds, and filter papers. It relates to an eco-friendly hybrid surface protection coating composition for a water-treated concrete structure exposed to a high-humidity environment that can provide an excellent surface protection effect to the concrete structure, and a method for surface protection construction of a concrete structure exposed to a high-humidity environment using the same. [Formula 1] In the above formula, a is an integer from 10 to 300;
