Description

[0002] Waterproof and anticorrosion method of tile with multiple functional layer structure for water treatment facility having multiple functional layer structures for water treatment facilities,

The present invention relates to a tile waterproofing method having a plurality of functional layer structures for a water treatment facility, and more particularly, to a waterproofing method for a waterproofing facility by forming a plurality of functional layers on a base surface for waterproofing construction, The present invention relates to a tile waterproofing method capable of enhancing the performance of a waterproof system inside a structure and a facility by performing a final finishing treatment by attaching a tile on the functional layer.

A water treatment facility is a facility installed to facilitate the flow of water and refers to facilities such as water, sewage, marine, agricultural, and industrial facilities, and supplies water necessary for urban life and marine, agricultural and industrial production smoothly to desired places. It is convenient to use large quantity of water and prevent water pollution so that various users can use water of good quality. If water quality is polluted or does not meet water quality standards, water quality treatment is performed.

In general, the concrete structures of such water treatment facilities are exposed to an environment where neutralization and chemical corrosion are easily caused by chlorine, chemicals, acid, alkali, and corrosive gas contained in the stored water, and the deterioration of the structure proceeds rapidly .

Particularly, residual chlorine is present in purified water and purified water using purified water using chlorine. In the case of advanced water treatment plant using ozone, water treatment is performed by utilizing the powerful oxidizing power of ozone having strong disinfecting power about 100 times or more as compared with chlorine So that the concrete structure of the chlorine contact paper and the ozone contact paper rapidly deteriorates.

As a waterproofing material for water treatment facilities, a lot of film-like materials are generally used for convenience and cost. Especially epoxy resin, ceramic metal, urethane, etc. are used as coating materials.

When epoxy resin and ceramic metal products are used, the waterproof function may be deteriorated due to a low elongation rate and cracks in the case of external impact or cracking of the matrix. In case of low temperature or winter work, the curing speed is slow, It takes a long time to work, and there is a disadvantage in that the adhesion to the substrate may be reduced due to incomplete curing of the material.

  In addition, epoxy resin-based products contain bisphenol A components which are environmental hormones, and when a coating-type material is applied, a certain amount of organic solvent may be used in the course of work, which may be harmful to human body and environment.

Urethane-based products have high elongation but have low ductility and mechanical properties due to their limited resistance to cracking, resulting in poor performance. They are mainly self-leveling type products and thus have poor workability for use on vertical surfaces or ceiling surfaces.

Such coating materials may cause problems such as surface dissolution, discoloration, peeling, cracking and peeling after the product is applied, so it is necessary to periodically maintain such as repair and repainting, Common problems with waterproofing by pinholes occur.

And the terminology used herein is for the purpose of illustrating embodiments and is not intended to be limiting of the present invention. The singular forms herein include plural forms unless the context clearly dictates otherwise.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Brief Description of Drawings FIG. 1 is a block diagram of a computer system according to an embodiment of the present invention; FIG. 2 is a block diagram of a computer system according to an embodiment of the present invention; FIG.

FIG. 1 is a view showing a procedure of a tile waterproofing method having a plurality of functional layer structures for a water treatment facility of the present invention, FIG. 2 is a view showing a tile waterproofing method having a plurality of functional layer structures for a water treatment facility of the present invention Sectional view of a water treatment facility according to the present invention.

Referring to FIGS. 1 and 2, the tile waterproofing method of the present invention includes a first step of pretreating a base surface, a second step of forming a first waterproof layer, a third step of forming a method layer, And a fifth step of forming a tile layer.

First, the first step is to remove the foreign matter on the base surface and to perform pretreatment in order to maintain the smoothness of the base surface for waterproofing construction.

Specifically, it is possible to remove foreign matter by jetting high-pressure through a jet-washing machine, and to clean the substrate surface by using a tool such as a grinder.

Between the first step and the second step, a sealing work for filling the cracked portion or a reinforcement work by the section repair method is applied to the portion where the crack, dropout or deterioration phenomenon has occurred on the pretreated substrate And may further include an ongoing basis maintenance step.

The second step is a step of forming a first waterproof layer by applying a waterproof resin to the base surface to prevent penetration of water on the pretreated base surface.

The waterproof resin may include 25 to 75 parts by weight of an alkaline aqueous solution per 100 parts by weight of at least one water-soluble polymer resin selected from water-soluble polyurea resin, water-soluble acrylic resin, water-soluble epoxy resin and aqueous EVA resin, And 2 to 5 parts by weight of Disteardimonium hectorite to which the effect is exhibited. Such a waterproof resin is for controlling the occurrence of durability deterioration factors of concrete.

In addition, the waterproof resin may contain 25 to 75 parts by weight of extender pigment, 5 to 30 parts by weight of pigment, 20 to 75 parts by weight of water, 2 to 5 parts by weight of wet dispersant, 2 to 5 parts by weight of defoamer, And 5 to 30 parts by weight of lithium hydroxide fixing the carbon dioxide discharged by the defoaming agent.

Specifically, it is preferable to use a water-soluble polyurea resin as the water-based polymer resin, which is excellent in chemical properties such as water resistance, chemical resistance and salt water resistance, mechanical properties such as abrasion resistance and impact resistance, This is because it has environment-friendly characteristics.

In addition, water functions as a solvent in the water-solubilizing process. It is preferable to mix water within the above range in order to facilitate water-solubilization of the water-based polymer resin and adversely affect the physical properties of the cured coating film. The water may be distilled water.

The alkaline aqueous solution is an alkaline aqueous solution having a pH of 11 to 12. The alkaline aqueous solution can improve the surface strength, water resistance and heat resistance by imparting alkalinity to the coating film of the first waterproof layer. In order to prevent corrosion of the concrete, For example, the alkaline aqueous solution may be one in which lithium silicate is dissolved in water.

In addition, the extender pigment acts to impart functions such as strength reinforcement and dimensional stability, and may be selected from the group consisting of talc, scorching, heavy carbon, silicon-based fillers, barium sulfate, aluminum hydroxide powder and mixtures thereof.

Further, the pigment is for imparting hue to the first waterproof layer, and the defoaming agent improves the wettability and improves the adhesion to the base surface and removes bubbles of the waterproof resin composition to improve the appearance and the denseness of the coating film to improve durability And lithium hydroxide fixes the carbon dioxide released by the defoaming agent to control the cause of the neutralization of the concrete.

In addition, the adhesion promoter has a function of reinforcing the adhesive force to the base surface and the strength of the first waterproof layer through chemical action on the waterproof resin composition by improving the viscosity. In the present invention, the adhesion promoter is a mixture of distearammonium hectolite (Disteardimonium hectorite) is used.

When a general thickener is used, a thickening effect is generated early in the process of stirring the components constituting the waterproof resin, so that sufficient agitation of the composition is not performed and the uniformity of physical properties is not secured. Particularly, The structure may not be uniformly filled and the bonding strength may be lowered.

Thus, distearammonium hectorite is used as the adhesion promoter of the present invention. However, the distearammonium hectorite is different from methyl cellulose (MS), which is a conventional adhesion promoter, Since the thickening effect is shown after a lapse of time, the timing of the thickening effect is somewhat delayed.

That is, the distearammonium hectorite provides a stirring time so that the waterproof resin composition can be uniformly mixed, and the viscous property is expressed after sufficiently mixing to uniformly fill the base surface having bending and cracking, So that a sufficient adhesion strength between the first waterproof layer is developed.

That is, by applying the waterproof resin in the second step, it is possible to prevent penetration of water into the inside of the structure, to reinforce the strength of the base surface, and to prevent neutralization and salt corrosion of the concrete.

The third step is a step of applying a fabric on the first waterproof layer and applying a pedestal resin of 0.5 mm to 1.5 mm so as to impregnate the fabric, thereby forming a method layer.

Specifically, the fabric refers to a synthetic resin fiber fabric, and various fabrics capable of improving the adhesion strength of a conventional layer such as a polyester fiber fabric, a polyethylene fiber fabric, a polyamide fiber fabric, and a nonwoven fabric may be used.

Further, the anticorrosive resin may contain 25 to 75 parts by weight of sieving and anticorrosive pigments, 5 to 50 parts by weight of the antifouling pigment, 100 parts by weight of the water-soluble polyurethane resin, water-soluble urethane resin, water-soluble acrylic resin, To 30 parts by weight of water, 20 to 75 parts by weight of water, 2 to 5 parts by weight of a wet dispersant, 2 to 5 parts by weight of a defoamer, 2 to 5 parts by weight of an adhesion promoter and 1 to 5 parts by weight of calcium nitrite.

Such an anticorrosive resin is for controlling the corrosion which lowers the durability of the structure, and it is possible to control the factors of deterioration of durability such as corrosion of the structure while being eco-friendly since it does not contain an organic solvent and compensate the disadvantages of the organic resin and the inorganic resin Physical and chemical properties can be improved.

The above-mentioned calcium nitrite is used for preventing the scale from being deposited due to corrosion of the surface of the structure to improve the rustproofing property. Even if a relatively small amount of the calcium nitrite is used without affecting the physical properties such as the strength of the caustic resin, Can be prevented.

Specifically, the functional small nitrite ion (NO ₂ ^- ) of calcium nitrite reacts with iron ions (Fe ²⁺ ) eluted from iron (Fe) to inhibit the formation of ferric hydroxide (Fe (OH) ₃ ) (Fe ₂ O ₃ ), which is a stable compound. The ferric trioxide (Fe ₂ O ₃ ) thus formed prevents the progress of corrosion of the iron by forming a film at the corrosion point formed on the surface of the structure and closing it.

Water-based polymer resins, extender pigments, pigments, water, wetting and dispersing agents, antifoaming agents and adhesion promoting agents of the epoxidized resin are the same as those mentioned above for the waterproof resin, and the explanation thereof will be omitted.

That is, in the third step, the corrosion layer is formed through the fabric and the caustic resin to prevent corrosion of the inside of the structure, and the structure responds to changes with time by moving with the behavior of the structure, , The interfacial adhesion force and the durability can be improved, and the neutralization and the salt corrosion of the structure can be prevented.

The fourth step is a step of forming a second waterproof layer by applying an inorganic tile adhesive to give an adhesive strength and a waterproof property to the anticorrosive layer.

In this case, the inorganic tile adhesive includes the waterproof resin or the caustic resin and an inorganic admixture, and the inorganic admixture has a length change rate of 0.01 to 2% according to KS L 1592 and a coverage rate of 80 to 93% It is preferable to satisfy it. The inorganic admixture may also be a product that meets the KC certification test standard.

Generally, a tile adhesive is used by mixing a certain amount of water with an inorganic material, which is good in strength and adhesion to a tile, but is inferior in bonding state between particles, and therefore, cracks tend to occur. The resistance to external impact is reduced and the impact resistance is lowered.

On the other hand, the second waterproof layer according to an embodiment of the present invention includes an inorganic admixture conforming to the KS L 1592 or KC certification test, and a waterproof resin or a septic resin so that the waterproof resin or the caulked resin functions as an organic binder It is possible to reinforce the bonding force between the particles, to improve the waterproofing or the performance, and to improve the crack resistance, the impact resistance and the adhesion force so that the stability of the applied structure can be maintained for a long time.

The inorganic admixture of the inorganic tile adhesive improves the thermal and physical strength, abrasion resistance, tear strength, corrosion resistance and weather resistance of the tile adhesive, imparts gloss and heat resistance, And can prevent the oxidation and deterioration of the coating film that occurs when exposed to a high temperature for a long time, and can be a ceramic powder capable of exhibiting radiation resistance.

For example, the ceramic powders of the present invention can be used in a wide range of applications, such as Illite-Mica, silica sand, elvan, ), Pyrophyllite, dolomite, lithium minerals, magnesite, bauxite, bentonite, pumice, borate, serpentine, , Acid clay, Iron oxide, Garnet, Carbonate minerals, Attapulgite, Sepiolite, Nephrite, Apatite, Feldspar, Feldspar, Perlite, Vermiculite, Zeolite, Barite, Talc, Diatomaceous earth, Graphite, Hectorite, Clay Minerals ), Zirconium Minerals, Titanium Minerals, Tourmaine, An airgel, a fly ash, a blast furnace slag powder, and a mixture thereof.

Preferably, the ceramic powder is mixed with various materials at a ratio more suitable than when it is used alone to improve the bonding strength between the particles, the cohesion of the coating film, the heat resistance and the waterproof performance, Corrosion resistance, abrasion resistance, and the like.

The fifth step is to attach a tile on the second waterproof layer and to form a tile layer by applying an inorganic tile joint to the tile joint.

At this time, the inorganic tile joint agent includes the waterproof resin or the caustic resin and an inorganic admixture, and the inorganic admixture has a length change rate of 0.01 to 0.1% according to KS L 1592 and a water absorption rate of 1 to 10% Is satisfied. The inorganic admixture may also be a product that meets the KC certification test standard.

Generally, a joint agent is used by mixing a certain amount of water with an inorganic material. This is because it is easy to cause cracks due to insufficient bonding state of materials, and the viscosity of joints is high, There is a possibility that leakage may occur due to infiltration of the storage water through the gap and deterioration of the performance of the jointing agent due to deterioration factors contained in the stored storage water may occur.

On the other hand, the tile layer according to an embodiment of the present invention includes an inorganic admixture conforming to KS L 1592 or KC certification test, and a waterproof resin or a caustic resin, so that the waterproof resin or the caustic resin functions as an organic binder The bonding force between the materials can be reinforced, and fluidity, crack resistance, impact resistance and adhesion can be improved to maintain a firmly closed state, so that the stability of the applied structure can be maintained for a long time.

The inorganic admixture of the inorganic tile joint agent improves the thermal and physical strength, abrasion resistance, tear strength, corrosion resistance and weather resistance of the tile joint agent, imparts gloss and heat resistance, And it is possible to prevent the oxidation and deterioration phenomenon of the coating film which occurs when the coating film is exposed to a high temperature for a long time, and thus it can be a ceramic powder capable of exhibiting radiation resistance. The specific description of the ceramic powder is the same as that described in the inorganic tile adhesive.

Further, the tile of the fifth step includes 30 to 40% by weight of clay, 25 to 35% by weight of white clay, 20 to 30% by weight of feldspar, 10 to 20% by weight of silica, preferably 32 to 35% By weight, 29 to 32% by weight of whitish earth, 23 to 26% by weight of feldspar and 12 to 15% by weight of silica.

Specifically, the tile is mixed with 30 to 40% by weight of clay, 25 to 35% by weight of whitened earth, 20 to 30% by weight of feldspar and 10 to 20% by weight of silica, (A) a molding step for molding a tile; (B) a first firing step of firstly firing the molded tile at 900 to 1200 ° C (preferably, 1000 to 1100 ° C); And (c) a second firing step in which the first fired tile is subjected to second firing at 1000 to 1300 ° C (preferably, 1100 to 1200 ° C). The tiles according to the present invention are preferably manufactured as described above, and tiles conforming to the certification standard according to KS L 1001 are preferably used.

(B-1) in which a functional coating agent is applied to the surface of the first fired tile and then aged at 100 to 400 ° C between the first firing step (b) and the second firing step (b) The functional coating agent application step may further be included. The functional coating agent may be one selected from the group consisting of a Teflon coating agent, a fluorine-based coating agent, a silicone-based coating agent, and a ceramic coating agent. Preferably, the functional coating agent may be a ceramic coating agent .

Wherein the ceramic coating agent comprises 45 to 60 wt% of a colloidal silica binder, 5 to 20 wt% of silica powder, 5 to 20 wt% of an inorganic pigment, 10 to 30 wt% of an alkoxide compound, 10 to 30 wt% of a solvent, % ≪ / RTI > by weight. Preferably, the coating composition is prepared by mixing 45 to 50 wt% of a colloidal silica binder, 8 to 13 wt% of silica powder, 8 to 13 wt% of an inorganic pigment, 15 to 20 wt% of an alkoxide compound, 15 to 20 wt% . ≪ / RTI >

The colloidal silicate binder is a colloidal silicate that performs a main binder function to form a coating film of a ceramic coating. Examples of the silicate include sodium silicate, calcium silicate, potassium silicate and alumina silicate. have. When the content of the colloidal silica binder is less than 45% by weight, the slip property and the strength of the coating film are lowered, and when the content is more than 60% by weight, the gel is easily gelated.

The silica powder serves to enhance the heat resistance, hardness, crack, and viscosity of the coating film of the ceramic coating. When the content is less than 5% by weight, the aforementioned effect is insignificant. When the content exceeds 20% by weight, , The surface of the coated film is roughened, and the viscosity of the ceramic coating agent is increased, thereby deteriorating the workability.

The inorganic pigment is involved in the color and appearance of the ceramic coating agent. When the content is less than 5% by weight, color and hiding power are lowered. When the content is more than 20% by weight, gloss and scratch resistance are deteriorated.

The alkoxide compound affects the slipping property and reactivity of the ceramic coating agent. When the content is less than 10% by weight, reactivity is deteriorated. When the content is more than 30% by weight, physical properties as a coating agent may be deteriorated.

The solvent serves to control the workability of the ceramic coating agent and the thickness of the coating film. If the content is less than 10% by weight, the spraying workability is negatively affected. When the content exceeds 30% by weight, the thickness of the coating film is thinned, Can be degraded.

It is preferable to use the additives included in the above range in order to reinforce the functional surface of the coating agent including the slip property of the ceramic coating agent, the leveling property of the coating film and the dispersion of the inorganic pigment.

The tiles to which the ceramic coating agent has been applied have excellent appearance as determined by naked eyes and have excellent properties of hardness, heat resistance, stain resistance, washability, abrasion resistance, water resistance, solvent resistance and water repellency.
