Description COATING MATERIAL FOR CONCRETE STRUCTURE AND
CONSTRUCTION METHOD USING THE SAME
Technical Field
[1] The present invention relates to a coating material for a concrete structure and a construction method using the same, and more particularly, to a coating material for a concrete structure with a three-dimensional network structure, which is good in various physical properties such as adhesion to a concrete, endurance, and freezing tolerance, and does not cause environmental contamination in construction, and is not harmful to the human body, and is not flammable, and thus is useful as a coating material for preventing water permeation and corrosion, and also for repairing and reinforcing concrete structures, and to a construction method using the same.
Background Art
[2] Generally, a concrete structure is used for special purposes such as in water treatment facilities, sewage treatment facilities and waste water treatment facilities in addition to use in general buildings. Such a special purpose concrete structure is exposed to various special physical and chemical environmental conditions which affect directly or indirectly the structure.
[3] To ensure resistance to physical and chemical environmental conditions, various materials such as waterproof materials, corrosion resistant materials, and neutralization preventing materials as coating materials for a concrete structure, and construction methods using these materials have been researched. In detail, epoxy corrosion resistant materials, urethane waterproof materials, permeable waterproof materials, spherical waterproof materials, and the like have been developed and used.
[4] For example, Korean Patent Laid-Open Publication No. 1989-005242 discloses a powdery waterproof material prepared by adding carbon black or aluminum sili cate- based inorganic powder to fatty acid metal salt and paraffin chloride and then mixing a polymer resin and a dispersant.
[5] In addition, Korean Patent Laid-Open Publication No. 2001-038592 discloses a spherical powdery waterproof material composition comprising silica fume as a main material and a higher fatty acid metal salt (zinc stearate), a superplasticizer, an AE water reduction agent, silica, etc. Disclosure of Invention
Technical Problem
[6] However, conventional corrosion inhibitors and waterproof materials do not withstand internal stress of concrete after passage of long time, easily break-down and have poor freezing tolerance. In particular, some of corrosion inhibitors and waterproof materials contain an organic solvent such as toluene or xylene, and thus cause environmental contamination and are harmful to the human body due to solvent evaporation in construction, and are combustible. Moreover, adhesion to concrete is reduced under a high humidity, which can result in incomplete construction.
Technical Solution
[7] The present invention provides a coating material for a concrete structure with a three-dimensional network structure, which is good in various physical properties such as adhesion to a concrete, endurance, and freezing tolerance, and does not cause environmental contamination in construction and does not have harmfulness to human body and fire hazard, and thus is useful as a coating material for preventing water permeation and corrosion, and is also useful for repairing and reinforcing concrete structures, and to a construction method using the same.
[8] According to an aspect of the present invention, there is provided a coating material for a concrete structure with a three-dimensional network structure, including a prepolymer having a hydrophilic functional group, a prepolymer having a hydrophobic functional group, and calcium aluminum silicate particles.

[24] An environmental protecting layer may be further formed on the second coating material for a concrete structure.

[31] The present invention will now be described more fully with reference to the accompanying drawings.
[32] The present invention relates to a coating material for a concrete structure and a construction method using the same, and more particularly, to a coating material for a concrete structure with a three-dimensional network structure, which is good in various physical properties such as adhesion to a concrete, endurance, and freezing tolerance, and does not cause environmental contamination in construction, and is not harmful to the human body, and is not flammable, and thus is useful as a coating material for preventing water permeation and corrosion, and also for repairing and reinforcing concrete structures, and to a construction method using the same.
[33] A coating material for a concrete structure according to an embodiment of the present invention is a matrix of a three-dimensional network structure, which is prepared by adding calcium aluminum silicate to a hybrid prepolymer including a prepolymer having a hydrophilic functional group and a prepolymer having a hydrophobic functional group. [34] The prepolymer having a hydrophilic functional group has an affinity to water and the prepolymer having a hydrophobic functional group has an affinity to oil. Thus, the hybrid prepolymer having both components has an adhesion to a concrete surface due to hydrophilicity and has a resistance to aging of the coating material due to lipophilicity.
[35] Further, since calcium aluminum silicate is added to the hybrid prepolymer to form a matrix of a three-dimensional network structure, hydrohardening occurs due to a chemical reaction with water, swelling property is maintained, and an adhesion to a concrete structure increases. Moreover, the coating material maintains integrity with a concrete structure to be formed and has high compressive strength and flexural strength, thereby increasing the endurance of the whole concrete structure. Thus, the coating material can be used to prevent water permeation and corrosion, and to repair and reinforce concrete structures.
[36] The prepolymer having a hydrophilic functional group may be represented by formula (1):

D - C - N - R1 - N - D - C - N - CH, - CH, - N - CH2- CH2- NH -^ Il Il ' Jn

(1)
[38] in which D is a dimeric acid having 12-18 carbon atoms, R is an alkyl group having 1-4 carbon atoms, and n is a positive integer of 10-100.
[39] The prepolymer represented by formula (1) is an amide amine prepolymer which has a hydrophobic hydrocarbon group and a hydrophilic amino group and has a surface acting property.
[40] The molecular structure of the prepolymer represented by formula (1) can enhance water solubility, maintain stability of an aqueous solution and be chemically modified to have improved compatibility to a hydrophobic glycidyl prepolymer represented by formula (2), which is described below, and be emulsified, which enables it to be used in the absence of an organic solvent. In addition, application and coating in a closed space are possible due to improved corrosion resistance and adhesion to a wet concrete surface and no flammability.
[41] The prepolymer represented by formula (1) can also be present in the form of the prepolymer represented by formula (2) by an imidazoline reaction which can enhance a surface acting property of the prepolymer having a hydrophilic functional group:

[43] in which D is a dimeric acid having 12-18 carbon atoms, and m is a positive integer of 10-100. [44] The prepolymer having a hydrophobic functional group may be represented by formula (3): [45]

[46] in which Ar is an aromatic ring having 6-24 carbon atoms, R is selected from the group consisting of O, OH, a methyl group, an ethyl group, and a butyl group, q is a positive real number of 0-4, and r is a positive integer of 1-10.
[47] The prepolymer represented by formula (3) is a diglycidylether-based compound which has a molecular weight of 340-2,000 and enhances the resistance to aging of the coating material.
[48] When the prepolymer having a hydrophilic functional group and the prepolymer having a hydrophobic functional group are mixed by fast dispersion etc., both prepolymers are hybridized to form an inter-penentrated network (IPN). Thus, a three- dimensional network structure is obtained.
[49] Meanwhile, the coating material for a concrete structure according to an embodiment of the present invention includes calcium aluminum silicate (CaO • Al O • SiO • xH O) in addition to the hybrid prepolymer. The calcium aluminum silicate is a hydraulic material which induces hydration and is covered with the three-dimensional network structure of the hybrid prepolymer film to form an inorganic and organic matrix through a physiochemical bonding.
[50] When the calcium aluminum silicate is covered with the hybrid prepolymer film to form a coating, flexibility to be adapted to a variation in temperature and an adhesion to a base concrete are ensured, leading to enhanced resistance to outer impact and cracking and good freezing tolerance and strong cohesion. In addition, resistance to a variation in interfacial stress generated in interfaces and coating layers of some concretes is ensured for a long period.
[51] Physical properties of the concrete structure coating material are also affected by the average particle diameter and the shape of calcium aluminum silicate particles added. The average particle diameter may be 80-325 meshes and the particle shape is preferably a spherical shape in terms of dispersity.
[52] When the average particle diameter of calcium aluminum silicate particles is less than 80 meshes, the hydrosis reaction is difficult. When the average particle diameter of calcium aluminum silicate particles is greater than 325 meshes, hydroskin occurs during dispersion.
[53] A construction method according to an embodiment of the present invention will now be described with reference to the accompanying drawings.
[54] A construction method according to an embodiment of the present invention includes: removing foreign materials from a concrete surface layer; depositing a base on the concrete surface layer; depositing a filler and a bottom leveling material on a layer of the base; and depositing a coating material for a concrete structure on a layer of the filler and the bottom leveling material.
[55] First, foreign materials on a concrete surface layer formed by a conventional method are removed. Foreign materials include laitance, pinhole, and other foreign materials. The removal of foreign materials can be accomplished using a wet sanding machine by a powerful jetting device. The removal of foreign materials is generally accompanied by a cleaning process using a high pressure sprinkler.
[56] Then, a base is deposited on the concrete surface layer. The base is deposited considering a curing and capillary treatment of concrete and interrelation with the coating material. Examples of the base include, are not limited to, a permeable primer such as aluminum silicate, an acryl primer, and an epoxy primer.
[57] Thereafter, a filler and a bottom leveling agent are deposited on a layer of the base.
The filler fills defects of the concrete surface. Examples of the filler include, but are not limited to, polymer cement mortar (PCM), epoxy cement mortar (ECM), and epoxy acryl cement mortar (EACM). The bottom leveling agent is deposited considering smoothness of concrete and affinity to the coating material and may be the same material as the filler.
[58] The concrete structure coating material of a three-dimensional network structure, including the prepolymer having a hydrophilic functional group, the prepolymer having a hydrophobic functional group, and calcium aluminum silicate is then deposited on a layer of the filler and the bottom leveling agent.
[59] The construction method according to the present embodiment may further including depositing an environmental protecting layer on the layer of the concrete structure coating material to improve acid resistance, alkaline resistance, chlorine resistance, and ozone resistance. Examples of a material for the environmental protecting layer include, are not limited to, a glycidyl prepolymer, an amine adduct prepolymer, and a composition including silica nanoparticles.
