ATA METHOD FOR PROTECTING IRON BAR AND REPAIRING REINFORCING AND COATING CONCRETE STRUCTURE USING SALT-RESISTANT AND WATER-RESISTANT ATA POLYMER
The present invention relates to a coating method for protecting a rebar and reinforcing a concrete structure using a salt resistant and seawater resistant ATA polymer. In reinforcement mortar, a modified ATA polymer in which 45 parts by weight of alkyltriethoxysilane, 15 parts by weight of a terpene-based resin, and 40 parts by weight of an acrylic polymer are synthesized is included as an anti-inflammatory agent. A urethane associative form is included as an operation performance improver. The ATA polymer is emulsified by synthesizing 45 parts by weight of the alkyltriethoxysilane, 15 parts by weight of the terpene-based resin, and 40 parts by weight of the acrylic polymer at 70-100C. The reinforcement mortar is obtained by mixing 30 to 50 parts by weight of Portland cement, 40 to 60 parts by weight of dolostone, 1 to 10 parts by weight of an expanding agent, 0.01 to 0.5 parts by weight of a urethane associative form operation performance improver, 1 to 10 parts by weight of an ATA polymer, 0.1 to 0.5 parts by weight of a reinforcing fiber, 0.1 to 10 parts by weight of a fluidizing agent, and 1 to 5 parts by weight of a silica fume. An alkali-imparting rust inhibitor is prepared in a liquid phase by mixing 10 to 30 parts by weight of lithium carbonate, 1 to 10 parts by weight of an ATA polymer, 0.01 to 0.5 parts by weight of a urethane associative operation performance improver, and 50 to 80 parts by weight of water. A primer is prepared in a liquid phase by mixing 10 to 30 parts by weight of an ATA polymer, 1 to 5 parts by weight of a urethane associative form operation performance improver, and 50 to 80 parts by weight of water. The reinforcement mortar is coated with a salt damage neutralization preventing heavy duty coating agent.
