Description

TECHNICAL FIELD The present invention relates to a synthetic rubber polymer adhesive-type waterproofing agent and a sealing waterproofing agent, a method for producing the same, a method of making the same, a method of constructing the same, a method of constructing the same, a method of constructing the same,

The present invention relates to a synthetic rubber polymer adhesive gel type waterproofing agent and sealing waterproofing agent, a construction method thereof, and a construction structure, and more particularly to a synthetic rubber polymer adhesive waterproofing agent, An injection sealing material, a waterproofing agent other than a retrofitting waterproofing agent, a thermal shrinkage waterproofing agent and a caulking material, a manufacturing method thereof, a construction method, and a construction structure.

Generally, the adhesive composite synthetic rubber based composite sheet is applied to a non-exposed outer waterproofing work of a concrete structure, and an adhesive gel is used. Adhesive gel is composed mainly of asphalt compound and contains a small amount of rubber component, special adhesive, inorganic powder, and surfactant.

Asphalt compounds are viscoelastic materials that are very vulnerable to temperature changes and break at low temperatures or flow down at high temperatures. Also over time, the asphalt compound will harden and lose its waterproof performance.

Particularly, when an adhesive synthetic rubber composite sheet is applied to a part having a large temperature change such as a roof, the oil component of the asphalt compound falls through the concrete crack or the joint due to the weakness of the asphalt compound.

On the other hand, the synthetic rubber polymer adhesive gel and the modified asphalt sheet are applied to the non-exposed portion of the concrete structure by an adhesive-gel-sheet composite waterproofing method. The adhesive gel material and the modified asphalt sheet contain asphalt compound as the main raw material and contain a small amount of rubber component.

The adhesive gel material and the modified asphalt sheet are produced in the form of a sheet at the factory, and the viscosity of the adhesive gel material is increased to form a composite sheet material by being laminated with the modified asphalt sheet with low fluidity.

In this case, oil is mainly used for controlling the viscosity of the adhesive gel material. After the composite sheet is re-applied, the high volatile oil component of the asphalt is adhered to the adhesion interface with the concrete structure by the external environment (for example, temperature, ultraviolet ray, .

As a result, the adhesive gel material is peeled off from the concrete structure to lose the adhesive force, and the asphalt compound is hardened as a whole by the de-oiling phenomenon (dry phenomenon), thereby deteriorating the waterproof performance. When the composite sheet material is applied to the wall, the flow resistance is lowered at a high temperature, and the adhesive gel material flows down or the composite sheet material itself flows down.

Also, it is difficult to apply the composite sheet material in the winter season when the temperature is lower than the predetermined temperature (-1 DEG C). Since the main component of the adhesive gel material is asphalt, the adhesive gel material quickly cures if the oil component is lost. As a result, the waterproof layer formed of the composite sheet material is lifted from the concrete structure.

Adhesive gel (sealing agent) is specified in KS F 4935. Sealing agents require water permeability resistance, wet surface adhesion, structural behavior, water resistance, chemical resistance and temperature dependence.

Even if these requirements are met, the long-term use of buildings and the like will make the temperature conditions more severe, and it is difficult to predict how safe the sealant will be. From this point of view, known sealing agents can cause some serious problems, while using substantially too wide a material without considering the characteristics of the material, they can actually have some effect. In fact, the sealing agent is flowing down at the high temperature in the summer when the sealing agent is applied.

Commonly used waterproofing agents have advantages and disadvantages. When the waterproofing agent is a polymer material, that is, an asphalt waterproofing agent, a film waterproofing agent and a bentonite waterproofing agent are used but they can be easily broken.

When the waterproofing agent is destroyed, the waterproofing agent will lose the waterproofing function. In addition, when the waterproof strength is lowered, cracks occur or damage occurs, the waterproofing agent partially loses its waterproof function easily.

When the waterproofing agent is a rubber waterproofing agent, the waterproofing agent has excellent strength and high elongation, but is relatively expensive. In addition, the unvulcanized rubber waterproofing agent generates a flow and does not completely block the hole. Vulcanized rubber sheets lose their water-proofing function when a hole is formed and have a self-adhesive function, but they do not adhere well to the surface of a waterproofing object.

On the contrary, the sheet-like waterproofing agent can easily cause a problem at the joining portion of the sheet, and can cause fire, odor and safety problems when it is heat-sealed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

The synthetic rubber polymer adhesive gel type waterproofing agent according to one embodiment of the present invention includes a rubber component, a reinforcing filler, a coupling agent, a dispersion and a room temperature stiffness adjusting agent, a flow control agent, a suspending agent and an auxiliary material.

The rubber component is composed of end-modified synthetic rubber, butyl rubber, butyl regenerated rubber and general regenerated rubber, and the content is 20 to 40% by weight. The reinforcing filler is selected from at least one kind of carbon black, aluminum hydroxide, silica and radmud, and the content is 10.0 to 30.0% by weight.

The coupling agent is used together with the reinforcing filler and has a content of 0.3 to 2.4% by weight. The dispersant and the room temperature stiffness modifier include modified asphalt and petroleum resin, and the content is 5.0 to 10.0 wt%.

The flow control agent includes process oil, modified regenerated cooking oil and polybutene, and the content is 30.0 to 60.0% by weight. The content of the crosslinking agent is 0.2 to 1.0% by weight. Ancillary materials are applied to rubber products as anti-aging, activating and accelerating agents to improve performance and have a content of 0.1 to 5.0% by weight.

The rubber component is made of a polymer material having rubber properties, and is generally selected to be able to maximize performance while satisfying required characteristics of tens or hundreds of raw rubber used in the market. By way of example, butyl rubber has excellent gas permeability and low double bonds, resulting in long-term durability. Therefore, the rubber component uses butyl rubber as one axis.

In order to appropriately control the slippage of the rubber, the rubber component is used in combination with a functionally modified polymer so that the terminal of the molecule can react with the filler. As a result, molecular entanglement, bonding between the filler and the molecule, And it is possible to stably realize flowability, shape stability and adhesiveness even in a wide temperature range.

Basically, since butyl rubber, carbon black and most organic materials are not hydrophilic, the adhesion and denseness of the sheet are poor in a humid environment. To prevent this, a hydrophilic filler is applied.

For example, hydrophilic fillers include silica, radmud and aluminum hydroxide. Synthetic rubbers introduce functional groups at the ends that can be combined with hydrophilic filler microparticles.

The end-modified rubber component used in one embodiment of the present invention has a molecular weight of 500,000 to 2,000,000, which is end-modified with a silica or metal affinity functional group, and has a glass transition temperature of -50 to -35 ° C. SBR butadiene rubber.

If the content of vinyl or styrene in SBR is too high, the properties of the rubber component at a low temperature are rapidly deteriorated. Therefore, SBR has a low vinyl content with a transition temperature of glass transition temperature of -50 to -35 占 폚 and has a styrene content of 20% to 35% by weight and a molecular weight of 500,000 to 2,000,000 in order to suppress the flow of molecules.

If the molecular weight is less than 500,000, the entanglement between the molecules is small and the flow is generated. If the molecular weight is more than 2,000,000, the sensitivity to temperature is improved and the problem of flow is suppressed, but the processing becomes difficult and the terminal- And the like.

Also, when the transition temperature of the vitrification is less than -50 DEG C, it becomes harder in the winter so that the construction is difficult and the sealing efficiency is lowered. If the transition temperature of the vitrification is higher than -35 ° C, the styrene content of the SBR must be lower than the reference amount. In this case, the content of styrene, which inhibited molecular slip at high temperatures, may be too small.

SBR rubbers can be used in a wide variety of types, so that if only one of the desired products is sufficient, only one type of rubber can be used. If not, it is preferable to mix the two types of rubbers having different molecular weights or different styrene contents, Can be lowered and the processing can be advantageously made.

Of course, the SBR of these commercial products may include process oil for rubber. In this case, the process oil included in the rubber component is converted into the process flow rate in the future.

The butyl-regenerated rubber is characterized in that the content of the butyl rubber in the reclaimed rubber is 45 to 65 wt%, the carbon black is 25 to 35 wt%, the acetone extract is 2 to 10 wt%, and the ash is 1 to 10 wt% The Mooney viscosity is 15 to 40 at.

The general recycled rubber contains a rubber component in an amount of 55 to 70% by weight, carbon black in an amount of 25 to 40% by weight, an acetone extract in an amount of 2 to 20% by weight and an ash in an amount of 1 to 20% ~ 65.

On the other hand, when the entire rubber component (considering pure rubber product) is taken as 100, the rubber component is composed of 10 to 35% by weight of end-modified synthetic rubber, 20 to 70% by weight of butyl rubber, 10 to 25% And 10 to 20% by weight of rubber, and the total number of double bonds in the total molecular skeleton is 5 to 25%.

Thus, the composition ratio of the rubber component is designed to be environmentally friendly using recycled materials in order to lower the cost, and to minimize the weakness while taking advantage of the characteristics of the material.

The end-modified synthetic rubbers contain functional groups that are compatible with reinforcing fillers such as silica, so they react with each other to help disperse and control the flow by the filler bound at the ends of the molecule. Therefore, the composition ratio of the end-modified synthetic rubber should be in the range of 10 to 35% by weight in order to control the partial crosslinking due to the advantage of the weather resistance and gas permeability of the butyl rubber and the double bonds, Is preferably within the above range.

The butyl rubber is excellent in basic waterproof performance, weatherability, and aging characteristics, but has a low double bond, which may interfere with cross-linking, and may also reduce the competitiveness of the product with expensive materials. In addition, the butyl rubber has a problem that the flowability is rapidly lowered at a low temperature, which may hinder the construction. Therefore, when used together with other materials, the composition ratio of butyl rubber is preferably in the range of 20 to 70% by weight.

Butyl regenerated rubber and general regenerated rubber greatly improve processability and cost competitiveness while maintaining the performance of each product. therefore

When the content of the butyl regenerated rubber is less than 10% by weight and the content of the general regenerated rubber is less than 10% by weight, the effect is insignificant. When the content of the butyl regenerated rubber is more than 25% by weight and the general regenerated rubber is more than 20%

The reinforcing filler is selected from the group consisting of one kind of carbon black which is the first inorganic filler selected from N500, N600 and N700 series, hydrophilic silica and aluminum hydroxide having a particle diameter of 0.5 to 10 占 퐉 in order to regulate reinforcement and molecular slip, And at least one second inorganic filler in Radmud, wherein the ratio of the first inorganic filler to the second inorganic filler is 20 to 60:40 to 80% by weight.

Of the second inorganic fillers, aluminum hydroxide or radmud is an environmental regenerating material, which maintains its performance while lowering the cost. However, when the particle diameter is less than 0.5 탆, it is expensive and may be an obstacle to dispersion during mixing. The property can be rapidly lowered. Silica is generally used as a silica blending agent for rubber.

The ratio of the first inorganic filler to the second inorganic filler should be such that the amount of the modified SBR having affinity with silica or the like and the butyl rubber compatible with carbon should be taken into consideration and, in consideration of the wetting adhesion, the second inorganic filler and the hydrophobic agent 1 The amount of carbon black (organic filler), which is an inorganic filler, should be appropriately harmonized. The ratio of the first inorganic filler to the second inorganic filler is preferably maintained at a content ratio similar to the content ratio of SBR and butyl rubber. However, considering the cost, etc., the performance ratio is in the range of 20 ~ 60: 40 ~ .

In order to maximize the hydrophilic performance, aluminum hydroxide has an aluminum hydroxide content of 99% or more and an average particle diameter of 0.5 to 10 탆. Red mud also has a particle diameter of 0.5 to 10 mu m. The silica may be a commonly sold precipitated silica.

 Aluminum hydroxide, silica, and red mud, together with carbon black, basically control the stiffness of the rubber and are physicochemically bonded to one segment and properly limit the intermolecular slip to balance flow and stiffness.

However, if the amount of the reinforcing filler is too large, it becomes too hard and can act as a waterproof layer, but the adhesion with the interface, the shape flexibility, the self-sealing function, and the sealing function are deteriorated. Also, the reinforcing filler has a need to appropriately adjust the ratio of lipophilic property to hydrophilic property.

The coupling agent is selected from SI-69 or SI-75, and it is 5 to 10% by weight of the content of the reinforcing filler excluding the carbon black.

Generally, the reaction amount of silica and silane is affected by the size of the particles and the amount of the functional group, but it is known that about 8% by weight is suitable. If the amount is less than 5% by weight, the reaction is insufficient. If the amount is more than 10% by weight, the cost increases.

Coupling agents are used together with rubber to maximize the effect of reinforcing fillers. This coupling agent reacts with silica, aluminum hydroxide or red mud and the ethyl group on one side to facilitate the dispersion of the reinforcing filler, and is integrated with the rubber by sulfur-sulfur bonding to enable appropriate control of intermolecular slip while maintaining flexibility .

Modified asphalt of dispersant and room temperature stiffener includes blown asphalt having a softening point of 80 to 100 캜.

If the softening point is lower than 80 캜, it may be bad to fall down in the summer season. If it exceeds 100 캜, it may adversely affect winter construction. Therefore, the amount of modified asphalt is important, but it is necessary to limit the softening point in order to maintain proper flowability.

In other words, the bloated asphalt is limited to those which can improve the mixability with the rubber, the strength of the rubber when used, the flowability, and the shape maintenance during long-term use. In Table 1, the blown asphalt is limited to segments 10-20 and 20-30.

Flow control agents include process oil for rubber, polybutene and modified regenerated cooking oil. In the flow control agent, the process oil preferably has a molecular weight of 400 to 700, a PCA (Polycyclic aromatic) concentration of 0 to 3%, a solubility index of 8.0 to 8.5, a polybutene molecular weight of 1000 to 2400, It was modified with glyceride.

If the molecular weight of the process oil is less than 400, it tends to easily leach out and leach to the surface. If the molecular weight of the process oil is more than 700, the function as the process oil (that is, facilitates mixing and proper sealing function) deteriorates.

The PCA concentration needs to be managed to minimize the environmental impact of process oil leaching. In tires, etc., it is already controlled within 3% in Europe. Therefore, for the environmental friendliness of products, less than 3% of process oil should be used. The lower the better, the better.

Stability after mixing of process oil is affinity with rubber etc. in addition to molecular weight. Considering that the solubility index of the commonly used butyl rubber is within 8.1 and the solubility index of the end-modified synthetic rubber (SBR) to be used is 8.0 to 8.4, the solubility index of the process oil is in the range of 8.0 to 8.5 I used it.

If the molecular weight of the process oil is lower than 400, it tends to easily leach out and leach to the surface. If it is higher than 700, the process oil functions to facilitate mixing, and has a proper sealing function.

The PCA concentration needs to be managed to minimize the environmental impact of process oil leaching. In tires, etc., it is already controlled within 3% in Europe. Therefore, for the environmental friendliness of products, less than 3% of process oil should be used. The lower the better, the better. Stability after mixing of process oil is affinity with rubber etc. in addition to molecular weight.

Considering that the solubility index of the commonly used butyl rubber is within 8.1 and the solubility index of the end-modified synthetic rubber (SBR) to be used is 8.0 to 8.4, the solubility index of the process oil is in the range of 8.0 to 8.5 I used it. That is, the solubility index of the flow control agent should be the same or similar to the solubility index of the butyl rubber and the end-modified synthetic rubber (SBR), so that phase separation does not occur during long-term use

Polybutene is one of the basic materials that make up the sheet, so if it is too low, it may show a phase separation with a rubber component having a very high molecular weight in the long term, and if it is too large, It falls out. The molecular weight of the most suitable polybutene is 1000 to 2400.

In addition, the PCA concentration minimizes environmental contamination during leaching through the use of flow control agents. For example, the process oil can be naphthenic oil, TDAE, tetrakis (dimethylamino) ethylene, or RAE oil.

Modified regenerated vegetable oil can be used in large quantities in terms of recycling of resources, but the compatibility may be deteriorated depending on the above solubility and molecular weight. If it is used as it is, it may deteriorate the mechanical properties, and phase separation may occur easily, and the amount of leaching may increase when used.

In order to overcome such disadvantages, the modified regenerated cooking oil is modified and used with a glyceride such as the formula (1).

15 to 30% by weight of process oil, 15 to 30% by weight of denatured regeneration oil, and 40 to 70% by weight of polybutene, when the sum of process oil, polybutene and modified regenerated oil is 100 in the flow control agent. When recycled rubber is used, the content of the process oil present in the reclaimed rubber can be calculated in terms of the process flow rate for rubber.

The use ratio of polybutene, process oil and denatured regeneration oil used as a flow regulator is the most favorable for long-term product stability of polybutene having no double bond and high molecular weight, but it is not only costly but also deteriorates in price competitiveness. In terms of compatibility, process oil and modified regeneration oil are rather superior.

However, if they are too much, the physical properties are also deteriorated in the long term. Therefore, it is preferable to mix them appropriately in terms of processability, cost, and long-term use stability. The evaluation results were found to be most effective when the ratios indicated in the examples were applied.

The crosslinking agent reduces the influence on the temperature of the waterproofing agent and forms a certain amount of cross-linking between the polymers in order to prevent the flow-down while being used for a long time and self-sealing.

The crosslinking agent comprises a sulfur-based crosslinking agent and a peroxide-based crosslinking agent. The sum of the sulfur-based crosslinking agent and the peroxide crosslinking agent is 0.5 to 2% by weight of the rubber component, 20 to 50% by weight of sulfur and 50 to 80% . As an example, peroxides use 1, 4 benzoquinone dioxime and 50: 50 benzoyl peroxide.

When the content of the rubber component in the whole components is small, the fraction of the crosslinking agent is preferably increased, and when the content of the rubber component is large, the fraction of the crosslinking agent is preferably small. When the amount of the crosslinking agent is more than 2% by weight, the amount of crosslinking is increased, and the flowability is remarkably lowered. In the future, cracks are formed or holes are formed, and the sealing effect is deteriorated. When the amount is less than 0.5% by weight, Which causes the problem to flow down.

The use of two types of sulfur and peroxide as cross-linking agent makes it possible to maintain a proper amount of crosslinking due to the nature of the materials which simultaneously use butyl rubber having a very small double bond content and at least 10 times more different synthetic rubber The stability of use and the property of crosslinking after storage at high temperature rather than pressure crosslinking were determined. Through various evaluations, when sulfur was 20 to 50 wt% and peroxide was 50 to 80 wt%, desired performance was exhibited. When the peroxide is 50 to 80% by weight, the desired performance is exhibited.

The cross-linking agent may further include stearic acid and zinc oxide so as to render crosslinking effective. This lowers the crosslinking speed and activation energy, shortens the storage time at high temperature for crosslinking, and maintains the effect even when the amount of crosslinking agent used is low.

Stearic acid is 1 to 1.5 weight% of the rubber component and zinc oxide is 2 to 5 weight% of the rubber component. When the content of stearic acid and zinc oxide is less than 1 and 2 wt%, respectively, there is little or no significant difference in use, and when 1.5 wt% and 5 wt%, respectively, there is no difference in physical properties. In addition, since stearic acid and zinc oxide react with each other and bring about such effects, the use amount of stearic acid and zinc oxide is preferably 1: 2 to 1: 3.

Meanwhile, the synthetic rubber polymer adhesive gel type sealant waterproofing agent of one embodiment may be prepared by mixing the synthetic rubber polymer adhesive gel type waterproofing agent and polybutene at a ratio of 1: 0.5 to 2 so that the sealing agent can be used as a sealing agent.

This ratio is intended to give sufficient flowability to give a narrow gap or a property to fill the hole. Therefore, if the ratio is less than 1: 0.5, the flowability is significantly lowered and the use as a sealing agent becomes impossible. If the ratio is more than 1: 2, the amount of polybutene is excessively increased and the problem of flowing in summer due to excessive flowability appears.

On the other hand, the above-mentioned waterproofing agent compositions are in a solid state, a liquid state, a powder state and the like, and their shapes are different from each other, and the strength and viscosity possessed by the material are very different. Therefore, it is difficult to obtain a desired water repellent product when the above compositions are merely mixed together. Thus, there is a need for appropriate manufacturing and processing procedures for the compositions.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a flow chart of a method of manufacturing a synthetic rubber polymer adhesive gel type waterproofing agent according to an embodiment of the present invention. 1, a synthetic rubber polymer adhesive gel type waterproofing agent manufacturing method of one embodiment includes a first step (ST1), a second step (ST2), a third step (ST3), and a fourth step (ST4) .

The first step (ST1) is a step in which the rubber component, the reinforcing filler, the modified asphalt, and the flow control agent within 50% by weight of the rubber component weight of the synthetic rubber polymer adhesive gel type waterproofing agent composition containing polybutene, Lt; / RTI >

In the second step ST2, when the mixed material in the first step ST1 is about 120 DEG C, the remaining flow control agent is further added thereto, mixed, and the coupling agent is added while the temperature is controlled at 120 to 150 DEG C Mix for 3 to 10 minutes, then sheet and cool to prepare the material.

In the third step ST3, the crosslinking agent and the auxiliary material are added to the mixed material in the second step ST2, and the mixed material is mixed for 2 to 3 minutes at 90 to 110 ° C.

The material is divided into the first step (ST1) and the second step (ST2) because when the flow control agent is all put together, the initial materials are not subjected to the shear stress and slip, .

In the second step (ST2), even if the remaining flow control agent is introduced at a too high temperature, the slip occurs severely in the mixer. The processing temperature and mixing time after the addition of the coupling agent is related to the temperature at which the coupling agent bonds the filler such as silica. If the temperature is less than 120 ° C, the coupling does not occur and dispersion is poor. If the temperature is higher than 150 ° C, sulfur contained in the molecular structure of the coupling agent is separated and the product can not be used because the crosslinking with the rubber is made in advance.

In the second step (ST2), if the mixing time is less than 3 minutes, the dispersion does not sufficiently occur and the mixed material can not exhibit the characteristics. If it exceeds 10 minutes, the sulfur of the coupling agent starts to react with the rubber, The efficiency may be greatly reduced.

In the mixing of the third step (ST3), the mixing and feeding of the materials to keep the maximum temperature not exceeding 110 deg. C maintains flowability and maximizes the dispersion of the material, So that a partial scorch phenomenon can occur and the product can be discarded. The mixing of the crosslinking agent and the auxiliary material for 2 to 3 minutes is also intended to prevent pre-crosslinking while securing sufficient dispersion.

In the first step (ST1), a part of the process oil and the denatured regeneration oil may be used as the flow control agent. In the second step (ST2), when the remaining flow control agent is added to the mixed material, the mixing time may be shortened or the mixing may be performed one to five times in consideration of the mixing efficiency.

In the fourth step ST4, the sealing waterproofing agent of synthetic rubber polymer adhesive gel type mixed with the material via the third step ST3 may be used after being stored at 120 to 140 DEG C for 2 to 8 hours.

When the sealing waterproofing agent of the synthetic rubber polymer adhesive gel type is stored at 120 to 140 ° C., the crosslinking agent and the materials in the mixed material react with each other to form appropriate crosslinking, The characteristics of the device can be improved.

If the storage temperature is less than 120 캜, crosslinking does not occur. Conversely, if the storage temperature is more than 140 캜, a difference in degree of crosslinking between the surface and the inside may significantly occur and the phases of the materials may be separated.

The storage time is set to a long time when the temperature is low and to a short time when the temperature is high. When considering the chemical reaction time, it takes twice as much time for every 10 ° C rise in temperature, but the time is estimated about 1.5 times considering the heat transfer reaction start time and adjusted appropriately according to the amount of cross-linking agent.

On the other hand, the synthetic rubber polymer adhesive gel type waterproofing agent prepared by the above-mentioned production method using the above composition can be applied by the construction method described below to form a construction structure.

FIG. 2 is a cross-sectional view of a construction method and a construction structure for applying a synthetic rubber polymer adhesive gel type waterproofing agent according to a first embodiment of the present invention, and FIG. 3 is a cross-sectional view of a synthetic rubber polymer adhesive gel type And a cross-sectional view of the construction structure.

Referring to FIGS. 2 and 3, in one embodiment, a method of applying a waterproofing agent includes a step of applying an adhesive gel, a step of forming a waterproof layer, and a step of tightly connecting the weakened portion to the waterproof sheet with an adhesive gel.

The fragile construction part includes a corner portion 11, a construction joint portion, a penetration portion 12 (see Fig. 3), a crack portion, a joint portion, or a sheet finish portion of a base of a concrete structure. In the step of applying the adhesive gel, the adhesive gel 20 formed of the synthetic rubber polymer adhesive gel type waterproofing agent of one embodiment is applied to the corner portion 11 and the penetrating portion 12 of the base body 10.

In the step of forming the waterproof layer, the waterproof layer (21, 31) is formed by applying a coating film waterproofing material or attaching a sheet on the substrate (10). The coating waterproofing material can be used by adjusting the viscosity of a general waterproofing material or a synthetic rubber polymer adhesive gel type waterproofing agent described above. That is, the adhesive gel 20 and the coating film waterproofing material may be composed of the same composition.

The step of tightly connecting the fragile construction part to the waterproof layer 21 and 31 with the adhesive gel 20 forms the waterproof layers 21 and 31 so that the adhesive gel 20 can prevent the waterproof layers 21 and 31 from being damaged 11 and the penetrating portion 12).

The waterproofing layers 21 and 31 can be firmly attached to the base body 10 in the corner portion 11 and the penetrating portion 12. [ The waterproofing layers 21 and 31 are pressed by the weak construction parts 11 and 12 so that the waterproofing layers 21 and 31 are fixed to the weak construction parts (the corner part 11 and the penetrating part 12) So as to be firmly and tightly connected.

The protector 30 provided on the outer surfaces of the waterproof layers 21 and 31 is formed of a film to protect the waterproof layers 21 and 31.

Since the adhesive gel 20 comprises butyl rubber as a main material and polybutene as a flow control agent, it has excellent properties in low temperature adhesion, tackiness maintenance period, weather resistance and long term durability stability.

Therefore, the construction structure includes the waterproof layers 21 and 31 formed on the substrate 10 and the adhesive gel 20 for reinforcement. The waterproofing layers 21 and 31 are formed by applying a coating material to the base 10 of the concrete structure or attaching a sheet.

The adhesive gel 20 is adhered to the fragile construction part such as the corner part 11, the penetrating part 12, a construction joint (not shown), a crack part, a joint part or a sheet finish part of the base 10, (21, 31) to the base body (10).

In the step of forming the sheet waterproof layer, a waterproof sheet is attached to the waterproof layer 41 to form the sheet waterproof layer 40. For example, the waterproof sheet may be formed of an improved asphalt waterproofing material, a self-adhesive butyl rubber waterproofing material, a synthetic polymer waterproofing material, or a synthetic resin based foamed waterproofing material.

The step of forming the waterproof protective layer attaches a protective film to the sheet waterproof layer 40 to form the waterproof protective layer 70. For example, the protective film may be formed of an HDPE film, a PP film, a nonwoven fabric or a stretch film. The waterproof protective layer 70 may be laminated on one side of the sheet waterproof layer 40 and manufactured in the factory.

Therefore, the construction structure includes a waterproof layer 41, a sheet waterproof layer 40, and a waterproof protective layer 50 which are sequentially formed on the base body 60. The coating film waterproofing material of the waterproof layer 41 can be environmentally friendly while maintaining viscous consistency by applying polybutene, a kind of liquid rubber, and a small amount of denatured regeneration cooking oil to the viscosity control of the subject of adhesive gel type of the embodiment.

On the other hand, a synthetic rubber polymer adhesive gel type waterproofing agent is attached to the sheet waterproofing layer 40 in the factory to form a laminated structure of the waterproofing layer 41, the waterproofing layer 40 and the waterproofing protective layer 70, It can be constructed by construction method.

The separable type is a method in which a synthetic rubber polymer adhesive gel type waterproofing agent is applied to the concrete base surface 60 as a whole in the field and then a general waterproof sheet (for example, the waterproof sheet 40 and the waterproof protective layer 70) The construction can be done in a way.

5 is a cross-sectional view of a construction method and a construction structure for applying a synthetic rubber polymer adhesive gel type waterproofing agent according to a fourth embodiment of the present invention.

The sealing waterproofing portion 81 and the maintenance waterproofing layer 84 filled in the crack portion 82 complement the outer waterproofing layer 83. The crack portion 82 can be punched so that the injector 85 can be installed in the crack portion 82 to easily inject the waterproof agent. Water pressure and earth pressure may act on the outside of the substrate 80.

In the case where there is no outside waterproof layer on the outside of the base body 80 (not shown in FIG. 5), an injection hole is bored in the base body 80 and an urethane is injected into the base body 80, After forming the waterproof layer, it is preferable to inject the waterproof agent into the injector 85 to form the sealing waterproof portion 81.

The non-retrofitted external waterproofing material is adhered to the earth retaining wall 91 adhered to the earth retaining wall 91 via the adhesive gel 92 and can be effectively applied to the sidewall section of the underground structure and the bottom floor of the underground floor.

A waterproofing material protection material 94 is attached to the self-adhesive butyl rubber waterproofing material 93. In the reverse waterproofing method of the underground structure, the adhesion of the poured concrete, that is, the adhesion between the earth retaining wall 91 and the outer waterproofing material is important. The butyl rubber waterproofing material 93 of the outer waterproofing material is sandwiched between the adhesive concrete 92 and the poured concrete Wall 91). The foundation concrete 95 is laid on the external waterproofing material (the self-adhesive butyl rubber waterproofing material 93 and the waterproofing material protection material 94) to form an endurance space of the underground structure.

The waterproofing material protection material 94 is formed of a water-soluble film and melted when the foundation concrete 95 is poured, so that the adhered butyl rubber waterproofing material 93 can be firmly attached to the earth retaining wall 91 and the foundation concrete 95.

As described above, the adhesive gel 92 and the self-adhesive butyl rubber waterproof material 93, which is an external waterproofing material, are sequentially attached to the earth retaining wall 91.
