Description

Rubber asphalt emulsion waterproofing material with improved adhesion to wet surface and waterproofing method using the same

The present invention relates to a rubber asphalt emulsion waterproofing material with improved adhesion to wet surfaces and a waterproofing method using the same.

In general, concrete structures such as water purification ponds, drainage basins, water supply, sewage/wastewater treatment plants, storage tanks and underground manholes or pits, and various offshore structures are mostly exposed or sealed structures, so it is inevitable to exclude the influence of infiltration of external inflows. In addition, it is often seen that the moisture content of concrete is more than 8%, and in severe cases, leakage due to cracks may occur in deep underground concrete structures.

In addition, in summer, dew is formed on the concrete surface due to the occurrence of dew condensation, which causes lifting or peeling of the waterproof and anticorrosive layer by using a waterproofing material that is difficult to attach to a wet base.

In other words, the concrete structure of the water treatment facility is not reviewed for performance maintenance and stability in the corrosive environment caused by chlorine and sulfuric acid as well as the structure containing a large amount of water structurally, and the conventional epoxy resin or polyurea (isocyanate composition) When using waterproofing methods (elastomers derived from the reaction product of urea and synthetic resin components), a separate drying process is required to dry the concrete surface, and epoxy resin or polyurea is applied to the concrete structure containing a lot of water During application, bubbles, pinholes, and lifting phenomena occurred, leading to poor construction quality and reduced durability.

In addition, the recent urban temperature has caused a heat island phenomenon due to air pollution, artificial structures, and vehicle exhaust gases. Due to this heat island phenomenon, tropical nights sometimes occur at night. To solve this problem, research and construction are being carried out to lower the temperature in the city center by coating the roads with heat shields in developed countries such as Japan. Policies and interest in lowering the urban temperature, such as the formation of green zones in the city, are gradually increasing.

1 is a view for explaining a rubber asphalt emulsion waterproofing material having improved adhesion to a wet surface according to an embodiment of the present invention.

The rubber asphalt emulsion waterproofing material (P) with improved adhesion to the wet surface according to an embodiment of the present invention is provided on the concrete base surface (C) of a building to add a waterproof function, but to improve adhesion to the wet surface, below For convenience of description, it will be referred to as 'this waterproofing material'.

Referring to FIG. 1 , the present waterproofing material (rubber asphalt emulsion waterproofing material (P) with improved wet surface adhesion according to an embodiment of the present invention) includes a primer (1) and a waterproofing agent (2).

The primer (1) is provided on the concrete base surface (C), and includes 100 parts by weight of tetraethyl orthosilicate or tetramethyl orthosilicate or a mixture thereof, and 70 to 190 parts by weight of an acryl silane copolymer.

Hereinafter, the component ratio of each component of the waterproofing material will be described based on 100 parts by weight of tetraethyl orthosilicate (TEOS) or tetramethyl orthosilicate (TMOS) or a mixture thereof.

Tetraethyl orthosilicate (TEOS) or tetramethyl orthosilicate (TMOS) or a mixture thereof is applied to improve the adhesion of the concrete substrate (C) to repel water and attach the coating solution when it is wet.

The acrylic silane copolymer reacts with concrete to give a strong bonding force and is injected for the purpose of improving adhesion with a waterproofing agent (2) to be described later applied on the primer layer.

At this time, 70 to 190 parts by weight of the acrylic silane copolymer (compound) is included. When the amount is less than 70 parts by weight, the adhesion performance with the concrete (concrete base surface (C)) is lowered, and when the combination ratio is 80% or more, the adhesion performance is significantly reduced. Problems arise, and when it exceeds 190 parts by weight, the thickness of the film becomes thick due to an increase in solid content, causing a problem in that drying is delayed.

When explaining the preparation method of the primer 1 by way of example, 100 parts by weight of TEOS is introduced into the reactor, and petroleum-based asphalt (eg, 50 to 185 parts by weight) is metered and put into the reactor. After adding these two compositions, the temperature inside the reactor is raised to 180° C., left for about 1 hour, waiting for the asphalt to dissolve in the TEOS, and then stirring is started at about 5 rpm. Stir at 5 rpm for 30 minutes, increase the stirring speed to 25 rpm and stir for 30 minutes.

After that, 70 to 190 parts by weight of an acryl silane compound (copolymer) is added and stirring is continued for 1 hour. After that, the reactant is cooled to room temperature and packaged in an appropriate container. The viscosity of the composition obtained at this time may be 400 to 480 cps (centipoise; 1/100 poise). As an exemplary acrylic silane chemical, POSCO's SR-S700 may be used.

When the primer (1) is not used as in the prior art, when the mixing ratio of the concrete base surface (C) is 60% or more, no coating (application) operation is performed at all, and a separation phenomenon appears immediately from the surface. Including (1), there is an advantage that the primer (1) repels water and is attached to the concrete to form a coating layer of the primer (1) regardless of the moisture content.

The waterproofing agent (2) is provided on the primer (1), 200 to 300 parts by weight of rubber asphalt, 0.2 to 1 parts by weight of silica sol, 10 to 50 parts by weight of polypropylene glycol-polyethylene glycol (PEG-PPG) and 5 to 20 parts by weight of titanium dioxide.

As the main raw material of the waterproofing agent (2), rubber asphalt is a material suitable for waterproofing because it has excellent elongation and hydrophobicity. However, since synthetic rubber and asphalt are dispersed in water, the film dries after coating, but the There is a disadvantage in that moisture does not escape from within the film, so drying is slow.

It is preferable that 200 to 300 parts by weight of rubber asphalt is used. When it is less than 200 parts by weight, it is difficult to obtain sufficient elongation because the content of rubber asphalt is small, and when it exceeds 300 parts by weight, the disadvantage of slow drying speed of rubber asphalt is maintained. .

Silica sol was used to increase the physical bonding strength of rubber asphalt to give it toughness, to increase the drying rate and to reduce the drying time.

When the silica sol is less than 0.2 parts by weight, it is difficult to increase the bonding force between the rubber asphalts, and when it exceeds 1 part by weight, it results in rather lowering the elongation of the rubber asphalt.

PEG-PPG not only wraps the rubber asphalt for smooth dispersion in water, but also pushes water to the surface and prevents the formation of a film on the surface.

When PEG-PPG is less than 10 parts by weight, the surface is dried first when coating the waterproofing agent (2), causing a problem that a dry surface is formed before all the water and solvent inside are volatilized, and exceeding 50 parts by weight In this case, there is a problem of lowering the elongation of the waterproofing agent (2).

Titanium dioxide serves to reflect infrared rays from sunlight, and the waterproofing agent (2) was used to absorb sunlight and suppress the temperature rise.

When titanium dioxide is included in less than 5 parts by weight, it is difficult to effectively reflect infrared rays and when it exceeds 20 parts by weight, the cost is excessively increased compared to the increase in the infrared reflection effect, so there is a problem that is not economical.

As described above, by including the waterproofing agent (2) in the present composition, it has excellent elongation and hydrophobicity to add waterproofness. And, in particular, by including titanium dioxide, there is an advantage that the temperature rise of the present waterproofing material due to sunlight can be suppressed by reflecting infrared rays of sunlight.

2 is a view for explaining the anti-condensation agent.

1 and 2, in a state in which this waterproofing material is applied to the concrete base surface (C), in a situation where the temperature is rapidly lowered, such as in winter, the temperature of the surface of the waterproofing material is rapidly decreased, so that dew condensation may occur on the surface of the waterproofing material. Also, if the water condensed on the surface of this waterproofing material freezes, slippage may occur and a great risk may occur.

In particular, as described above, the waterproofing agent (2) contains titanium dioxide and suppresses the temperature rise of the waterproofing material due to sunlight. Therefore, there is a need to suppress the occurrence of dew condensation of this waterproofing material in a low temperature situation such as winter.

Therefore, the waterproofing agent (2) of the present waterproofing material (corresponding to reference numeral GS in FIG. 2) may contain 1.5 parts by weight of the dew condensation inhibitor (G).

When the condensation inhibitor (G) is described in more detail with reference to FIG. 2, the condensation inhibitor (G) is 0.2 parts by weight of an impact heat generating agent (G1) containing sodium acetate, tolylene diisocyanate and ethylenediamine ( 0.1 parts by weight of endothelial agent (G2) containing polyurea formed through interfacial polycondensation of ethylenediamine) 0.3 parts by weight of shelling agent (G3) containing sulfur-cured ethylene-propylene diene monomer (Ethylene Propylene Diene Rubber) , 0.2 parts by weight of a cationic agent (G4) containing magnetite, polyacrylic acid, and polyoxyethylene, an aspect ratio of 20 or more, and a thermal conductive spacer (G5) containing carbon fiber 0.4 It may contain 0.3 parts by weight of the pressurizing agent (G6) including iron (fe) by weight.

Referring to FIG. 2 , the impact pyrogen (G1) of the condensation inhibitor (G) is an aqueous solution containing sodium acetate, and the solvent may be, for example, water, and the sodium acetate may be dissolved in the solvent in a supersaturated state. .

The impact heating agent (G1) is supersaturated with a solvent, and is in a very unstable state, so it hardens easily even with a slight impact, and can release heat contained in a liquid state. The impact heat generating agent G1 may generate heat by being impacted by a pressurizing agent to be described later.

It is preferable that 0.2 parts by weight of the impact heating agent (G1) is included, and when the amount of the impact heating agent (G1) is less than 0.2 parts by weight, the heating effect is not large, and when it exceeds 0.2 parts by weight, the weight of the condensation inhibitor (G) increases and the waterproof function In the second (2), there is a problem that the effect of suppressing dew condensation is reduced by sinking downward.

The endothelial agent G2 surrounds the impact heating agent G1, and as described above, may include polyurea formed through interfacial polycondensation of tolylene diisocyanate and ethylenediamine.

When tolylene diisocyanay and ethylenediamine are stirred, interfacial polycondensation forms a shell (endodermis), but the presence of unreacted amine and the mixing process of oxygen and nitrogen atoms or other molecules in the waterproofing agent (2) A positive charge can be formed by attracting positively charged hydrogens, etc. present in the , through dipole interactions.

Illustratively, the impact heating agent (G1) may be accommodated in the endothelial agent (G2) in a liquid state by being heated after being stirred with tolylene diisocyanay and ethylenediamine in a solid state, and the impact heating agent (G1) is the endothelium The process existing inside the second (G2) is not limited to the above method and may vary.

The endothelial agent (G2) preferably contains 0.1 parts by weight. When the amount of the endothelial agent (G2) is less than 0.1 parts by weight, the impact heat generating agent (G1) containing 0.2 parts by weight cannot be sufficiently wrapped with a sufficient thickness to form a liquid impact heating agent ( G1) may be lost, and when it exceeds 0.1 parts by weight, there is a problem in that the heat generated by the impact heating agent (G1) is not easily transferred to the outside of the dew condensation inhibitor (G).

The envelope (G3) surrounds the endothelium (G2) as shown in FIG. 2 and is disposed outside the endothelium (G2), as described above, with sulfur-cured ethylene-propylene diene monomer (Ethylene Propylene Diene Rubber) 0.3 It may contain parts by weight.

Ethylene-propylene diene monomer (EPDM) is obtained by adding a non-conjugated diene during the hybrid polymerization of ethylene and propylene, and has excellent water resistance and ozone resistance.

Illustratively, the EPDM may include an ethylene-propylene copolymer, treated calcined kaolin vinyl silane, stearic acid, zinc oxide, trimethylquinoline, a paraffinic plasticizer, a processing aid, and a conductive carbon black.

EPDM is a hybrid polymer capable of peroxide or sulfur vulcanization, and EPDM with added sulfur has a faster shrinkage rate at a low temperature of 5° C. or less than EPDM with added peroxide.

That is, the sulfur-cured ethylene-propylene diene monomer is sulfur-added to the EPDM, and may further include dithiomorpholine, tetramethylthiuram disulfide, dibutyldithiocarbonate zinc, and ethylene thiourea in addition to sulfur.

It is preferable that 0.3 parts by weight of the sulfur-cured ethylene-propylene diene monomer in the shelling agent (G3) is included, but when less than 0.3 parts by weight is used, the coating agent (G2) to be described later and the heat conduction spacer to be described later are not sufficiently wrapped with a sufficient thickness. If it exceeds 0.3 parts by weight, the weight of the anti-condensation agent (G) increases and sinks in the water-repellent agent (2), so a problem may occur in the function of the anti-condensation agent (G).

The cationic agent (G4) is provided on the outer and inner surfaces of the shelling agent (G3), respectively, and as described above, magnetite, polyacrylic acid and polyoxyethylene are included. Thus, it was used to add the polarity of the envelope (G3).

Magnetite is magnetic when it receives an external magnetic field, but when the external magnetic field is removed, the residual magnetism disappears and there is no side effect due to residual magnetism. The magnetite may be embedded in the outer and inner surfaces of the envelope G3, respectively.

Polymethacrylic acid is coated on the surface of the magnetite, and contains a plurality of carboxyl groups to form a coordination bond with the magnetite at multiple bonding points, so that it is possible to increase the coating stability.

Polyoxyethylene may react with a carboxyl group that does not form a coordination bond with magnetite on the surface of polymethacrylic acid to form a stable bond through an amide bond to impart positive charge properties to the magnetite. The positive surface charge of the cationic agent (G4) may have a surface zeta potential of +30 mV or more.

It is preferable that 0.2 parts by weight of the cationic agent (G4) is used. If it is less than 0.2 parts by weight, the positive charge is not sufficient. There is a problem of sinking in the functional agent (2).

The heat conduction inhibitor (G5) is provided between the endothelial material (G2) and the sheathing material (G3) to separate the endothelial material (G2) and the sheathing material (G3). fibers were used. The carbon fiber may have a thermal conductivity of about 200 W/mK, and may serve to transfer the heat generated by the impact heat generating agent (G1) to the shell material (G3) side.

It is preferable that 0.4 parts by weight of the heat conduction inhibitor (G5) is included. If it is less than 0.4 parts by weight, heat conduction is not sufficient. There is a problem with increasing it.

The pressurizing agent (G6) includes iron, is provided on the inner surface of the envelope (G3) to protrude inward, and may be provided in plurality at intervals from the inner surface of the envelope (G3).

The pressurizing agent (G6) applies an impact to the impact heat agent (G1) by pressing the impact heat agent (G1) as the shell material (G3) contracts, and preferably contains 0.3 parts by weight, but less than 0.3 parts by weight If it is, it is not possible to apply a sufficient impact to the impact heating agent (G1), and when it exceeds 0.3 parts by weight, there is a problem in that the weight of the condensation inhibitor (G) is excessively increased.

[A] of FIG. 2 shows a state in which the envelope (G3) is not contracted at a temperature exceeding 5°C. The sheathing agent (G3) and the endothelial material (G2) are spaced apart by a heat conductive spacer (G5), and their length in a state in which the sheathing material (G3) is not contracted, such as at a temperature exceeding 5°C of the above-described pressurizing agent Since the distance between the tentative sheathing agent G3 and the endothelial material G2 is shorter, the pressurizing agent G6 cannot pressurize the impact heating agent G1 in a state in which the sheathing agent G3 is not contracted.

As described above, since the envelope (G3) and the endothelial material (G2) have a positive charge, the endothelium (G2) and the envelope material (G3) generate a repulsive force, so that the envelope (G3) is not contracted. The pressurizing agent provided on the inner surface of the agent (G3) suppresses the pressure of the endothelial agent (G2).

In addition, when there are a large number of units (GU) of the anti-condensation agent (G), it causes the neighboring units (GU) to be spaced apart from each other by the repulsive force between the positively charged envelopes (G3). The dispersibility of (G) can be improved.

[B] of FIG. 2 is a view showing a state in which the envelope (G3) is contracted at a temperature of 5°C or less. If the temperature of the waterproofing agent (2) falls below 5°C in the state in which the waterproofing agent (2) containing the dew condensation inhibitor (G) is applied, as described above, the shelling agent (G3) contracts As a result, the separation distance between the sheathing material (G3) and the endothelial material (G2) is reduced, and the pressurizing agent (G6) provided on the inner surface of the sheathing material (G3) penetrates the distance between the carbon fibers or between the pores of the carbon fibers. By pressing the endothelial material (G2), an impact can be applied to the impact heating agent (G1) provided inside the endothelial material (G2).

The shock generating agent (G1) generates heat as an impact is applied, and the heat is transferred to the shell agent (G3) through the heat conduction spacer (G5), and the waterproofing agent (2) through the shell agent (G3) ) is increased to effectively suppress the formation of dew on the surface of the waterproofing agent (2).

Through this, there is an advantage that it is possible to suppress (condensation suppression) from freezing dew formed on the surface of the present composition in cold weather such as winter.

It goes without saying that the envelope (G3) may be liquefied again later by the impact heating agent (G1) or heat applied from the outside to be restored to a reusable state. Various known techniques may be used for externally applying heat to the envelope (G3).
