Abstract

The present invention relates to an inorganic-based neutralization-proof, water-proof, and erosion-proof paint composition for a floor finish material, capable of being applied, without a primer, in a wet state with a concrete water content of 100%, and a method for applying a neutralization-proof, water-proof, erosion-proof flooring material, using the composition. The purpose of the present invention is to provide an inorganic-based neutralization-proof, water-proof, and erosion-proof flooring material paint composition and an application method using the same, the composition being applied directly on a concrete structure without a primer, even in a wet state with a water content of 100%, and thus having excellent impact resistance, air permeability, and slip resistance. The method of the present invention comprises a foreign substance removing step for removing foreign substances on a base surface of a concrete structure; a wetting step for creating a wet state by spraying water, 1-2 hours before application of the composition, on the base surface of the concrete structure from which the foreign substances have been removed; and a paint film-forming step for forming a paint film by coating and curing an inorganic-based flooring material paint composition on the base surface of the concrete structure provided in the wet state, wherein the inorganic-based flooring material paint composition comprises, with respect to 100 parts by weight of an aqueous solution phase, 200-300 parts by weight of an inorganic powder, the aqueous solution phase being an acrylic aqueous solution having a solid content of 15-50 wt%, and the inorganic powder comprising, with respect to 100 parts by weight of a binder powder, 45-70 parts by weight of a silica powder, 15-22 parts by weight of an inorganic pigment, 0.5-4 parts by weight of an alumina cement, 0.31-0.5 parts by weight of a polycarboxylate (PC) based dispersant, 0.2-0.4 parts by weight of a powder antifoaming agent, 0.1-0.2 parts by weight of a surface stabilizer, and 0.05-0.1 parts by weight of a bentonite.

Description

technical field [0001] The present invention relates to inorganic material anti-neutralization, waterproof, anti-corrosion, ground finishing material coating composition and anti-neutralization, waterproof, anti-corrosion, ground material construction method using it, specifically, need not to coat primer in 100 It can also be directly applied to the surface of concrete structures when the air humidity and concrete water ratio are 100%, and it has excellent adhesion, impact resistance, permeability and skid resistance, chemical resistance, water resistance, and abrasion resistance. , non-combustibility, and can be used as anti-neutralization, waterproof, anti-corrosion, and floor finish materials, which do not require primers and are environmentally friendly inorganic coating compositions and construction methods using them. Background technique [0002] The pillars, beams, walls, and ground of general concrete structures and steel structures are the most exposed structural ...

Problems solved by technology

[0014] Moreover, when the concrete structure is wet, the concrete structure should be completely dried to reduce the moisture content to below 8%, and then the primer and polymer cement mortar can be applied, because the moisture on the surface will increase the difficulty of construction

[0015] In particular, most of the water purification tanks and distribution tanks managed by the government and local governments in the sewage facilities are not permeable inside most of the water tanks installed in residential complexes and buildings, and organic products with low moisture resistance are applied, so twice a year When cleaning and inspecting the water tank, the coating materials are likely to fall off, bulge, and blisters occur, and in the process of applying organic coating agents for maintenance, the relevant personnel are easily suffocated and injured by organic solvents, and the gas generated by organic solvents permeates the tank. various adverse phenomena such as the inability to use the stored water
