BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a process diagram of an outer wall waterproofing method of a stucco brick or a concrete building using an inorganic silicone coating agent according to the present invention.
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
The outer wall waterproofing method of a stucco or concrete building using the inorganic silicone coating agent according to the present invention is characterized in that it comprises a base surface preparation step (S1), a joint part maintenance step (S2), an inorganic silicone coating agent application step (S3) And a drying step S4.
The ground surface smoothing step S1 is a step of arranging the surface of the base surface to be installed or to be repaired, for example, the surface of the rough brick wall or the concrete wall.
This is done by using a wire brush or a disk sender to clean the surface of the workpiece with a high-pressure washer or an air compressor after removing contaminants from the contaminated area or deteriorated area.
In the joint area repair step S2, it is checked whether or not the joint surface of the joint brick wall to be repaired, that is, the joint surface of the joint brick wall, is corroded or broken through the ground surface clearance step S1, Is filled and repaired.
Alternatively, in the case where the base surface is a concrete wall, it includes a step of filling the portion where the concrete has been dropped off or the portion where the void is generated, with the protective mortar.
The inorganic silicone coating agent applying step S3 is a step of applying an inorganic silicone coating agent to the masonry brick or the concrete wall that has been repaired by jointing through the joint repairing step S2. In this case, the inorganic silicone coating agent is preferably applied about three times, but it is not limited thereto, and it is applied at least once according to the condition of the substrate.
On the other hand, the inorganic silicone coating agent is composed of distilled water, a coating agent, an antifouling agent, a surfactant, an adhesion promoter, and a dispersant.
Wherein the coating agent comprises 45 to 60 parts by weight of dimethysiloxane, 10 to 20 parts by weight of methyltrimethoxysilane, 10 to 18 parts by weight of butyl alcohol, 10 to 18 parts by weight of octyltriethoxysilane, 9 parts by weight of tetrabutyl titanate, and 7 to 9 parts by weight of tetrabutyl titanate.
When the amount of the dialkyl siloxane is less than 45 parts by weight, the water repellency may be deteriorated in the long term. If the amount is more than 60 parts by weight, required properties are not improved and the production cost is increased due to addition of raw materials.
If the methyltrimethoxysilane is less than 10 parts by weight, the permeability may be lowered. If the amount is more than 20 parts by weight, the physical properties may not be improved and the manufacturing cost may be increased due to addition of raw materials.
If the amount of the butyl alcohol is less than 10 parts by weight, the solvent does not sufficiently perform its role. If the amount of the butyl alcohol exceeds 18 parts by weight, the physical properties are not improved and the production cost is increased due to addition of raw materials.
If the octyltriethoxysilane is less than 7 parts by weight, permeability may be lowered. If it is more than 9 parts by weight, the physical properties may not be improved and the production cost may be increased due to addition of raw materials.
If the amount of the tetrabutyl titanate is less than 7 parts by weight, the initial hydrostatic force is lowered. If the amount is more than 9 parts by weight, the catalyst does not need to serve as a catalyst.
The antifouling agent is 10 to 20 parts by weight based on 100 parts by weight of distilled water. Preferably, the antifouling agent is diethoxyhydroxymethylsilane. In this case, the surface tension of the antifouling agent is lowered when the diethoxyhydroxymethylsilane is less than 10 parts by weight, and when the amount is more than 20 parts by weight, the surface tension may increase and the application may not be performed smoothly.
The surfactant is 3 to 5 parts by weight based on 100 parts by weight of distilled water. The surfactant is preferably polyoxyethylene ether and methoxypolyoxyethylene methacrylate. In this case, if the amount of the polyoxyethylene ether is less than 3 parts by weight, the emulsification stability of the inorganic silicone material is lowered to cause gelation, while if it exceeds 5 parts by weight, the water resistance is lowered.
If the content of methoxypolyoxyethylene methacrylate is less than 3 parts by weight, the emulsification stability of the inorganic silicone material is lowered to cause gelation. When the amount of methoxypolyoxyethylene methacrylate is more than 5 parts by weight, the water resistance is lowered.
The adhesion promoter is 10 to 30 parts by weight based on 100 parts by weight of distilled water. The adhesion promoter is preferably dihydrotetramethyldisiloxane. In this case, when the amount of the dihydrotetramethyldisiloxane is less than 10 parts by weight, the bonding strength is lowered and the adhesive is peeled off after the application. If the amount exceeds 30 parts by weight, the physical properties are not improved and the manufacturing cost is increased due to the addition of the raw material.
The dispersant is 0.2 to 0.4 parts by weight based on 100 parts by weight of distilled water. The dispersant is preferably polyoxyethylene nonylphenyl ether. In this case, if the amount of the polyoxyethylene nonylphenyl diisocyanate is less than 0.2 parts by weight, the water dispersibility is deteriorated. If the amount is more than 0.4 parts by weight, hygroscopicity is increased.
The inorganic silicone coating composition as described above is sprayed onto a masonry wall by spraying, brushing or roller to prevent foreign matter or moisture from penetrating to improve the durability of the masonry brick walled with the masonry brick . Of course, the present invention is not limited to this and is applied to a concrete wall made of concrete to prevent foreign matter adsorption or moisture penetration.
In addition, when the existing stucco brick wall or the concrete wall is required to be maintained by deterioration or aging due to environmental or external factors, the inorganic silicone coating agent is applied to prevent foreign matter adsorption or moisture penetration, .
In addition, the inorganic silicone coating agent may further include a reflective coating agent that produces an aesthetic appearance as it is reflected when exposed to sunlight.
The reflective coating is 0.2 to 1 part by weight based on 100 parts by weight of distilled water. The reflective coating is preferably a glass grain. The size of the free grains is preferably 0.05 to 0.5 mm. In this case, if the glass grains are less than 0.2 weight part, the effect of reflecting sunlight is lost. If the glass grains are more than 0.5 weight part, the physical properties are not improved and the manufacturing cost is increased due to addition of raw materials.
If the size of the glass grains is less than 0.05 mm, the effect of reflecting sunlight buried in the other composition is deteriorated. If the size of the glass grains is more than 0.5 mm, it may protrude to the wall and cause injury to workers.
Further, the free grains are preferably transparent but not limited thereto, and opaque or semitransparent colored materials can be used.
Further, the reflective coating agent is not limited to glass grains, and any material that can reflect sunlight can be used.
The drying step (S4) is a step of maintaining the inorganic silicone coating agent applied on the base surface to dry in a natural drying manner through the inorganic silicone coating agent application step (S3).
This is because the inorganic silicone coating agent applied on the substrate is allowed to stand in a natural dry state for 12 to 24 hours so as to be dried.
On the other hand, if the temperature of the atmosphere or the base surface, that is, the coarse brick wall or the concrete wall, is expected to be 5 ° C or less or less than 5 ° C within 24 hours, It is also preferable to stop the application even when the ambient temperature is 35 DEG C or higher.
The present invention is not limited to the above-described embodiment, but is only one embodiment for carrying out the outer wall waterproofing method of a brick or concrete building using an inorganic silicone coating agent. It will be understood by those skilled in the art that various changes may be made without departing from the spirit of the invention.
