Description

Roof protection mortar surface reinforcement waterproof structure and its waterproofing method {THE WATERPROOFING STRUCTURE BY PROTECTIVE MORTAR SURFACE'S REINFORCEMENT AND THEREOF METHOD}

The present invention relates to a rooftop protective mortar surface-reinforced waterproofing structure and a waterproofing method thereof. More specifically, the rooftop urethane coating film is classified into two types according to the existing rooftop waterproofing type by protecting the protective mortar matrix and acrylic coating waterproofing. The present invention relates to a rooftop protective mortar surface-reinforced waterproof structure and its waterproofing method that solve the shortcomings of the waterproofing method, and extend the economical efficiency of rooftop waterproofing maintenance and the waterproofing life of the rooftop through reinforcing surface and waterproofing acrylic coating.

In general, the structure of the existing rooftop waterproofing layer has a non-exposed waterproofing layer and a protective mortar layer structure in which one or several of the waterproofing methods such as cement liquid waterproofing, asphalt waterproofing, sheet waterproofing, and urethane coating waterproofing are applied in combination.

In this case, the non-exposed waterproof layer located under the protective mortar layer, which is divided into the roof waterproof layer, is the waterproof layer, and is configured to apply the protective mortar to protect the waterproof layer.

In addition, a heat insulating material may be constructed between the main waterproof layer and the protective mortar for internal insulation. That is, no matter which waterproofing method is chosen, the protective mortar is responsible for protecting the waterproofing layer.

Conventionally, the urethane-based waterproofing method has been widely applied on the protective mortar layer to protect the waterproof layer.

That is, it is constructed by dismantling the whole or part of the protective mortar layer on the rooftop, restoring the protective mortar layer, and applying the urethane-based waterproofing agent again.

However, the existing coating film waterproof construction method of such a structure has a first problem in proceeding the coating film construction without considering the original waterproof structure of the building to which the existing urethane coating waterproofing application.

The second problem is that the pretreatment process for the final coating layer to adhere properly to the mother is omitted or insufficient.

In other words, the pretreatment process for coating film construction is very important. This can be ensured by removing and reinforcing the neutralized part of the existing mother or removing foreign matters accumulated in the existing mother to secure the adhesive force between the mother and the coating film, otherwise it may cause peeling peeling in a short period of time, resulting in poor waterproofing.

In addition, in the selection of the coating film material, the third problem is selecting the urethane material.

Usually, urethane-based waterproofing agents do not allow water vapor to pass through.

Therefore, as shown in FIG. 1, a coating film applied on the rooftop slab layer 10, the present waterproof layer (non-exposed waterproof layer) 20, the heat insulating layer 30, the protective mortar layer 40, and the protective mortar layer 40. Water vapor is present in the micro spaces between the layers below the waterproof layer, and the water vapor generates internal condensation due to winter indoor heating and external cold air.

At this time, the generated condensation water is present in the protective mortar layer 40, and neutralizes the protective mortar layer 40 while repeating freezing and thawing through the winter and summer seasons, and peeling the coating layer from the surface of the protective mortar layer 40. To provide a cause.

In other words, when the protective mortar layer 40 freezes with condensation water, the condensation water expands by about 4% in volume, and the expansion of the condensation water leads to the destruction of mortar. If the existing water is repeatedly freeze-thawed as the temperature rises and falls repeatedly, the concrete loses its properties and the neutralization is accelerated, and the coating agent inevitably peels off from the surface.

In order to solve the problem of dew condensation caused by water vapor inside the rooftop waterproof structure, a construction method has been introduced. However, the dew condensation occurs only at room temperature because it is the winter season. The function of the ventilator could not be utilized in winter, which was not a perfect solution.

In addition, the rooftop protective mortar shares a role for protecting the present waterproofing layer (non-exposed waterproofing layer) 20, and in general, it is expected that the waterproofing performance will be improved by adding a double waterproofing layer to the protective mortar.

However, the problems related to the waterproofing of the roof can not be solved only by the protection mortar coating waterproofing, which flows along the material separation part inside and outside the roof railings and along the reinforcing bars, along with the waterproof press jaw crack and the back of the waterproof jaw. Due to the inflow of water through the masonry of the structure such as inflow, rooftop beet, inflow through the rooftop roof and the wall frame, water leakage penetrates into the protective mortar. Because.

Therefore, the addition of the urethane-based waterproofing layer to the rooftop waterproof structure in which the present waterproofing layer 20 is functioning is redundant, resulting in a waste of budget.

In particular, the construction method that has been constructed in the past has not been considered the rooftop waterproof structure, but the rooftop film waterproofing construction has been made without forgetting the original role of the protective mortar, which results in damage to the protective mortar and shorten the life of the waterproof performance, It has been causing economic losses due to refurbishment and problems with the stability of building structures.

Therefore, it is necessary to prevent the waste caused by the impurity urethane-based waterproofing construction, to restore the original role of the protective mortar on the roof of the building, to realize the waterproofing performance and durability of the waterproofing layer, and to provide a new waterproofing method that is efficient and economical in maintenance and management in the long term. Was done.

The present invention was created in view of the above-mentioned problems in the prior art as described above, and improves the existing urethane-based coating type waterproof structure applied indiscriminately without considering the existing rooftop waterproof structure, but protects the waterproof layer. The strength of mortar is restored to the state of initial construction by strengthening the surface of protective mortar and forming a suitable film waterproofing layer to give neutralization prevention function, thus increasing the life of protective mortar and providing economical maintenance and repair methods. The main purpose is to provide a roof protection mortar surface-reinforced waterproof structure and its waterproofing method to enhance the durability.

The present invention provides a means for achieving the above object, in a waterproof structure comprising a rooftop slab layer, the present waterproof layer formed on the rooftop slab layer, and a protective mortar layer formed on the present waterproof layer; 10 to 20% by weight of xylene, 5 to 10% by weight of methyl isobutyl ketone (MIBK), isopropyl alcohol (Iso propyl) to infiltrate the protective mortar to the upper surface of the protective mortar layer to strengthen the mother alchol) 20 to 30% by weight and 80 to 86% by weight of epoxy resin consisting of epoxy resin, and a curing agent consisting of 50 to 60% by weight of xylene and 40 to 50% by weight of polyamine.

In addition, in the waterproof structure comprising a rooftop slab layer, the present waterproof layer formed on the rooftop slab layer, and a protective mortar layer formed on the present waterproof layer; 10 to 20% by weight of xylene, 5 to 10% by weight of methyl isobutyl ketone (MIBK), isopropyl alcohol (Iso propyl) to infiltrate the protective mortar to the upper surface of the protective mortar layer to strengthen the mother alchol) 20 to 30% by weight and 80 to 86% by weight of epoxy resin consisting of epoxy resin, and a curing agent consisting of 50 to 60% by weight of xylene and 40 to 50% by weight of polyamine. Further forming a surface curing enhancement layer consisting of a mixture consisting of 14 to 20% by weight; The upper surface of the surface curing enhancement layer 50 ~ 60% by weight of ethylene vinyl acetate copolymer (Vinyl Acetate Ethylene Copolymer) to remove the uneven portion and the neutralization site, 1 ~ 2% by weight of additives to improve the reactivity and the balance 10-15 wt% of the first mixture composed of an aqueous solution, 10-15 wt% of calcium oxide, 35-45 wt% of silica sand or sand having a particle size of 0.4-0.8 mm for viscosity control and strength development After further forming a water reinforcement layer mixed with 85 to 90% by weight of the mixture; On the upper surface of the reinforcing layer, 1 to 1.5% by weight of titanium oxide (Titanium Dioxide), 1 to 1.5% of trimethyl-2.4-pentanediol-1.3-isobutyrate (2.4-trimetyl-1.3-pentandiol isobutyrate) to reinforce waterproofing and breathability 3 wt%, ethylene glycol 1-3 wt%, Calcium Carbonate 30-40 wt%, Acrylic Emulsion 40-50 wt%, Cyanine Green as coloring material 5 It is also characteristic that the acrylic coating film waterproof layer which consists of -8 weight% and remainder aqueous solution (water) is further formed.

On the other hand, the present invention is characterized in that the expansion joint is further formed on the surface of the protective mortar layer in which the surface curing enhancement layer is formed.

In addition, the present invention is a waterproof method for waterproofing to have a waterproof structure including a rooftop slab layer, the present waterproofing layer (non-exposed waterproofing layer) formed on the rooftop slab layer, and a protective mortar layer formed on the present waterproofing layer; A protective mortar layer surface pretreatment step of increasing adhesion by removing moisture, foreign matter, etc. remaining on the surface of the protective mortar layer; Performing expansion joint or cutting / joint enlargement on the surface to absorb the width of the protective mortar layer which has been subjected to the pretreatment step; Reinforcing the surface of the protective mortar layer by forming the surface curing reinforcement layer described above on the upper surface of the protective joint or the cutting / joint enlargement protective mortar layer; It also provides a roof protection mortar surface strengthening waterproofing method characterized in that it comprises the step of forming a repair reinforcement layer described above in order to repair reinforcement of the uneven portion or the neutralized portion remaining on the upper surface of the surface hardening reinforcing layer do.

In this case, after the step of forming the reinforcing reinforcing layer, the step of reinforcing the stretched joint portion with an elastic agent on the reinforcing reinforcing layer, and further comprising the step of forming the acrylic coating waterproof layer to improve the waterproofing and breathability of the reinforcing reinforcing layer It also has its features.

The present invention provides the following effects.

First, by dividing the existing rooftop waterproofing structure into two types and applying the appropriate method to each waterproofing structure, the optimized waterproofing function of the existing rooftop waterproofing structure can be secured in the long term.

Second, instead of applying the urethane coating waterproof layer on the roof, the protective mortar hardened by curing does not absorb moisture because it is a method of preventing the neutralization by the contact of carbon dioxide (CO ₂ ) by strengthening the surface and forming an acrylic coating waterproof layer. As the risk is lowered and neutralization is prevented, there is no damage of protection mortar freezing and thawing, so the life of protection mortar lasts longer, which increases the water resistance endurance of the waterproofing layer and provides economics in terms of application and maintenance.

Third, by providing the injection index method and the crack repair method for the damage leakage portion, structural defect leakage portion, etc. of the waterproof layer, it is possible to obtain a practical and effective waterproof effect, thereby providing convenience for easy repair and maintenance.

1 is an exemplary cross-sectional view showing a rooftop waterproof structure of a conventional general structure.
2 is an exemplary cross-sectional view showing a rooftop waterproof structure according to an embodiment of the present invention.
3 is an exemplary cross-sectional view showing a rooftop waterproof structure according to another embodiment of the present invention.

In the present invention, the durability of the present waterproofing layer (non-exposed waterproofing layer) is divided into a long term type that is about 20 to 30 years, and the durability of the present waterproofing layer is classified into a short term type. Long-term types include asphalt waterproofing (3 layers of 8 layers), sheet waterproofing, composite waterproofing, and short-term types include urethane waterproofing and cement liquid waterproofing.

That is, the present invention is divided into two types of long-term and short-term type according to the current waterproof layer durability of the existing rooftop waterproofing layer and provides a waterproof structure that can satisfy all of them, and also provides a waterproofing method accordingly.

At this time, the present waterproof layer of the existing rooftop waterproof structure is configured for a long time, if the state of the protective mortar is good, there is no need to apply a separate coating waterproof layer. The lifespan of the long-term waterproofing layer is estimated to be valid for 30 ~ 40 years with good maintenance. The protective mortar on the long-term waterproofing layer only needs to be protected to protect the waterproofing layer from damage by UV rays or external shocks. That is, rather than applying the coating waterproofing agent to achieve the waterproof purpose, it should be constructed in a direction to prevent the neutralization by the contact of carbon dioxide (CO ₂ ) on the surface of the protective mortar and to remove the water trap portion (reverse gradient) [see Fig. 2] .

On the other hand, the water-proof layer of the existing rooftop waterproof structure is a short-term type can be effective coating waterproof. Inorganic waterproofing layers, such as cement liquid waterproofing, are not applicable to large rooftops because they have less crack trackability and have much lower durability than other unexposed waterproofing layers. Therefore, in the rooftop waterproof structure having such a short-term main waterproof layer, an acrylic coating waterproof layer capable of suppressing generation of condensation water due to water vapor permeability is preferable [see FIG. 3].

Of course, the portion due to the classification of the existing rooftop waterproof structure is a part related to the rooftop mortar, and the waterproof performance of the entire rooftop is not secured only by the waterproofing for the mortar. Therefore, it is natural that an appropriate crack site repair method and a leak site injection index method are combined.

 Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

In the present invention, when the present waterproofing layer of the existing rooftop waterproofing layer is composed of a long-term unexposed waterproofing layer, the existing urethane-based waterproofing construction is avoided in order to maximize the performance of the original waterproofing layer.

Waterproof structure according to an embodiment of the present invention, more preferably the long-term rooftop waterproof structure as shown in Figure 2 is a rooftop slab layer 10, the present waterproof layer 20, the heat insulation layer 30, the protective mortar layer 40 In the existing waterproof structure made of, the protective mortar layer 40 has a structure further comprising a surface curing enhancement layer 50, the repair reinforcement layer 60.

At this time, the surface curing reinforcement layer 50 and the reinforcing reinforcement layer 60, as mentioned in the prior art, is made of a special component rather than the urethane-based for simple waterproof film as conventional.

That is, the surface curing reinforcement layer 50 is a layer for strengthening the parent mortar layer 40, for example, neutralization and removes foreign substances on the surface.

In this case, the elastic joint may be formed on the surface of the protective mortar layer 40 in which the surface curing reinforcement layer 50 is formed in order to absorb the behavior width of the protective mortar layer 40 due to shrinkage and expansion as necessary. .

In addition, the surface curing reinforcement layer 50 is preferably using an epoxy resin, the epoxy resin is excellent in the penetration of the protective mortar and penetrates up to 10 ~ 30mm greatly contribute to strengthen the mother.

In this regard, the surface curing enhancement layer 50 according to the present invention is 10 to 20% by weight of xylene (Xylene), 5 to 10% by weight of methyl isobutyl ketone (MIBK), and 20 to 30% by weight of isopropyl alcohol (Iso propyl alchol). And 80 to 86% by weight of epoxy resin composed of balance epoxy resin, and a curing agent consisting of 50 to 60% by weight of xylene and 40 to 50% by weight of polyamine in 14 to 20% by weight. It is a mixture composed.

At this time, an epoxy diluent may be further added depending on the degree of neutralization of the rooftop floor.

Here, the xylene refers to dimethylbenzene and is a material that is not used in water but is important as a raw material of synthetic resin.

In the present invention is used as a reactive organic solvent with the epoxy resin, to stabilize the epoxy resin and at the same time improve the adhesion.

To this end, the xylene should be added in 10 to 20% by weight, the reactivity is lowered when added to less than 10% by weight, the viscosity is increased when the content exceeds 20% by weight is preferably limited to the above range because the mother permeability is reduced. .

In addition, the methyl isobutyl ketone is an aliphatic compound that is stable at room temperature and normal pressure.

Such methyl isobutyl ketone is utilized in the present invention as an antioxidant for coating applications and epoxy resins.

To this end, the methyl isobutyl ketone should be added in the range of 5 to 10% by weight, when added in less than 5% by weight, paintability and antioxidant properties are lowered, and when it exceeds 10% by weight, the reactivity is increased to inhibit the expected effect. Therefore, it should be limited to the above range.

In addition, the isopropyl alcohol dissolves nonpolar substances and is used as a solvent for paints and inks.

Such isopropyl alcohol is added to enhance the mother permeability of the epoxy resin in the present invention, the most preferred amount is 20 to 30% by weight for this purpose.

The polyamine is an aliphatic hydrocarbon having two or more amino groups, and is used as an organic polymer flocculant in the present invention.

Accordingly, the polyamine is prepared as a curing agent having a curable property by reacting with xylene, which is a solvent, and mixing at a ratio of about 1: 1 is most effective for expression of properties.

The surface curing reinforcement layer 50 having such a function and component composition ratio is reinforced to strengthen the protective mortar layer 40 as a parent.

Subsequently, the uneven part or the neutralized part of the repair section and the reverse gradient part formed on the surface of the surface curing reinforcement layer 50 forms a repair reinforcing layer 60 using a mixture of acrylic resin as a binder.

That is, the reinforcing reinforcement layer 60 repairs and reinforces the irregularities and reverse gradient surroundings or the neutralization sites generated on the upper surface of the surface curing reinforcement layer 50 to form a uniform layer as a whole.

At this time, when the reinforcing reinforcement layer 60 is constructed with general cement mortar, since the peeling phenomenon occurs easily from the bottom when the thickness is thin, this should be avoided.

In addition, the reinforcing reinforcement layer 60 is 50 to 60% by weight of ethylene vinyl acetate copolymer (Vinyl Acetate Ethylene Copolymer), 1 to 2% by weight of additives for improving the reactivity and the remainder aqueous solution in order to minimize the peeling phenomenon 10-15 wt% of mixture, 10-15 wt% of calcium oxide, 35-45 wt% of silica sand or sand with a particle size of 0.4-0.8 mm for viscosity control and strength development, 85-90 By weight percent.

Here, the ethylene vinyl acetate copolymer is added for the crosslinking reaction, the crosslinking reaction is saturated if more than 60% by weight, if less than 50% by weight the crosslinking reaction for repair reinforcement is limited to the above range This is preferred.

On the other hand, as shown in Figure 3, the short-term type has a structure in which the acrylic coating waterproof layer 70 is further formed on the reinforcing reinforcement layer 60 of the above-described long-term structure.

This is to further reinforce the waterproof function, because it is desirable to have a structure that can remove the moisture and water vapor remaining in the interior by applying the breathable acrylic coating layer waterproof layer 70.

To this end, the acrylic coating waterproof layer 70 is 1 to 1.5% by weight of titanium oxide (Titanium Dioxide), 1 to 3% by weight of trimethyl-2.4-pentanediol-1.3-isobutyrate (2.4-trimetyl-1.3-pentandiol isobutyrate) , Ethylene glycol 1-3 wt%, Calcium Carbonate 30-40 wt%, Acrylic Emulsion 40-50 wt%, Cyanine Green 5-8 wt% as a coloring material It is preferably composed of% and the balance aqueous solution.

At this time, the titanium oxide is excellent in the cohesive force to agglomerate with each other by the static electricity on the surface of the fine particles are utilized as a cohesive enhancer for the index.

In addition, titanium oxide reacts with ultraviolet rays as a photocatalyst and is a physicochemically stable substance that is harmless to the human body.

In the present invention, a small amount is added, but due to the binding property with other components, there is a significant difference in cohesiveness and fluidity.

In addition, the trimethyl-2.4-pentanediol-1.3-isobutylate has high stability against hydrolysis and oxidation, and has high viscosity, and is low in stickiness, and is useful for improving both cohesiveness, elasticity and fluidity.

When such trimethyl-2.4-pentanediol-1.3-isobutylate is added in an amount less than 1% by weight, the viscosity decreases and cohesiveness decreases, and when it is added in excess of 3% by weight, the viscosity increases and inhibits fluidity. This is preferred.

In addition, the ethylene glycol is one of the simplest dihydric alcohols as a compound widely used as an automotive antifreeze, has no smell and taste in the pure state, and has a sticky property.

In the present invention, it is preferable to add the same content as the trimethyl-2.4-pentanediol-1.3-isobutylate in consideration of fluidity.

In addition, the calcium carbonate is calcium carbonate and is used as various neutralizers such as cement raw material, raw material of calcium oxide, and steel construction material.

In the present invention is added for the neutralization of concrete, in particular contributes to the removal through the reaction with carbon dioxide.

To this end, in the present invention, the calcium carbonate should be added and mixed at 30 to 40% by weight, but if added to less than 30% by weight, the neutralization is lowered, and if it exceeds 40% by weight, the alkalinity of the entire component is inhibited, so that the range is limited to the above range. desirable.

The emulsion is used as a plasticizer.

If the emulsion is added in less than 40% by weight, the plasticity is lowered, the elasticity is inhibited, if the emulsion exceeds 50% by weight it is to be added in the above range because the plasticity is not maximized to obtain a leakage blocking effect.

In addition, the coloring material is for realizing the color of the surface after application, but is not particularly limited and is preferably added in the above range.

The rooftop protective mortar surface strengthening structure according to the present invention having such a component composition can be constructed as follows, and the long-term type will be described as a standard model.

In addition, it is to be understood that the layers used in the structures described below are layers composed of the above-described component composition.

First, the protective mortar layer surface pretreatment step is performed.

The protective mortar layer surface pretreatment step must be preceded to remove adhesion of moisture, foreign matter, etc. remaining on the surface.

In addition, in the place where the rolling phenomenon such as the rooftop railing occurs, the width of the protective mortar layer is increased due to shrinkage expansion, and thus the peeling phenomenon is promoted. Therefore, expansion and contraction is necessary in order to prevent the maximum absorption width. The joint or cutting / joint enlargement step is performed.

Thereafter, the protective mortar layer surface strengthening step is performed.

The protective mortar layer surface reinforcing step is to make the protective mortar penetrates to a depth of 10 ~ 30mm to strengthen the layer itself, for this purpose, the surface curing reinforcement layer consisting of the composition of the above-described composition is formed on the protective mortar layer. .

In addition, a repair reinforcement step is performed to repair and strengthen the uneven portion, the inverse gradient surrounding, and the neutralized portion formed on the surface of the surface curing enhancement layer.

The repair reinforcing step is performed by applying a repair reinforcing layer composed of the above-described composition on the surface curing reinforcement layer.

Finally, a step of elastically reinforcing the stretched joint part after the reinforcing step is performed, and the step may be excluded as necessary.

In the case of the short-term type in addition to the long-term type that is waterproofed in this way, the coating layer waterproof layer may be further formed of an acrylic elastic coating agent composed of the above-described component composition after the last step.

As described above, the waterproof structure and the waterproofing method according to the present invention prevent the neutralization of the protective mortar layer of the roof structure and make it breathable, thereby making it possible to have a long service life while suppressing peeling and peeling due to residual moisture.
