Description

[0001] The present invention relates to a composite panel sliding protecting material having improved anti-condensation property and heat insulating performance,

The present invention relates to a protective material provided on the outer side surface of the waterproof layer in order to protect the waterproof layer during waterproofing and prevents the waterproof layer from being damaged by external pressure, friction or impact in the finishing step of waterproofing The present invention also relates to a composite panel sliding protecting material having improved dew condensation preventing property and heat insulating performance for preventing heat transfer inside and outside of a structure to prevent environment improvement and defects inside the structure.

Generally, underground concrete structures such as subways, underground roads, power sheds, open spaces, and tunnels, concrete structures such as underground parking slabs, underground parking slabs, and building rooftops are weak in waterproofing, As a result, not only the bonding force of the concrete itself is lowered, but also cracks may occur in the concrete due to the volume change of the water depending on the temperature change of the outside and the inside of the concrete. Therefore, in order to prevent the water from penetrating into the concrete structure It is waterproof.

In particular, in the case of an underground concrete structure constructed underground such as an underground outer wall surface of a subway, an underground driveway, an apartment, a building, etc., an outer wall waterproof layer is formed on the outer side wall surface to prevent water from penetrating into the concrete structure, In order to protect the outer wall waterproof layer, it is possible to stack the cement bricks on the surface of the outer wall waterproof layer and the outer surface of the outer wall waterproof layer where the concrete structure does not abut, i.e., the outer wall waterproof layer, or a foamed polyethylene foam board, a foamed urethane foam board or a foamed polystyrene foam board The waterproof layer protecting material is adhered on the outer wall waterproof layer and then the soil layer is formed by the sandy soil or sandy soil mixed with the gravel such as soil and stones to form a soil layer or a pressed concrete layer or a fine layer And the waterproof construction is finished.

Among the waterproof layer protection material for protecting the waterproof layer, the method of protecting the waterproof layer has been used for a long time since the waterproof layer protection method has been used for protecting the waterproof layer from the damage of the waterproof layer due to the earth pressure when filling the soil with the solidity of the cement brick , There is a disadvantage in that it is difficult to build bricks in a narrow underground work space, excessive overhead of construction labor costs, and a long period of work, resulting in a long construction period.

As an alternative to the problem of installing the waterproof layer protective cement bricks used as the waterproof layer protection material, a foamed polyethylene foam board, a foamed urethane foam board and a somewhat less expensive foamed styrene foam board are attached to the waterproof layer, The concrete slab is pressed and the upper slab surface or the wall surface is subjected to soil backfilling.

Various foam boards Waterproofing layer protectors are easy to install and the material itself has certain elasticity and resistance to impact. However, after the foam board is installed on the wall surface, the foam board is pressed against the waterproof layer So that the waterproof layer is damaged.

Also, even if the protective material is not damaged during the soil backfilling operation or the pressing concrete construction as shown in FIG. 1, if the settling pressure of the soil material mixed with the soil material or gravel is lower than the existing waterproof material protective material 20, The waterproof layer 10 is formed on the concrete structure 1 because the existing waterproof layer protection material 20 applied to the waterproof layer 10 attracts and flows down the waterproof layer 10. In this case, There is a possibility that a problem of dropping out of the apparatus may occur.

In addition, since only the conventional waterproof layer protection material 20 flows down and is spaced apart from the waterproof layer 10, a space is formed between the waterproof layer and the waterproof layer 20, and the problem of the durability of the existing waterproof layer protection material 20 If the existing waterproofing layer protection material 20 is damaged due to subsequent settlement of the ground, the waterproofing layer 10 can no longer be protected from the groundwater settlement.

The present invention relates to a foamed polyethylene board having a concave-convex foamed polyethylene board as an exposed face, and a rubber-asphalt compound having excellent adhesiveness and elasticity is coated on one side of the foamed polyethylene board to a predetermined thickness in Registration No. 20-0458991 (Feb. It protects the waterproofing layer which may occur during the subsequent finishing process such as concrete pouring and pressing down of the waterproof layer after the waterproofing of the concrete structure by installing it on the waterproof layer and the insulation and the anchor plate which can be reliably bonded to the waterproof layer A waterproof protective material having a water-repellent layer is proposed.

However, in the case of the conventional waterproof layer protection material, the exposed surface is formed of a foamed polyethylene board, so that the pressure is applied due to the subsidence pressure, the friction applied from the outside, There is a problem that the protective layer can no longer be protected because the protective layer is likely to flow down, break or be damaged.

Before describing in detail the preferred embodiments of the present invention, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary meanings and meanings consistent with the technical idea of the present invention As well as the fact that

Throughout this specification, when a member is located "above" another member, it includes not only the case where another member is in contact with the other member but also the case where another member exists between the two members, "Upper" may be "lower ", or" side "

Also, throughout this specification, when a section is referred to as "including " an element, it is to be understood that the description does not exclude other elements, but may include other elements, unless specifically stated otherwise.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

First, the composite panel sliding protective material having improved dew condensation preventing property and heat insulating performance of the present invention has a waterproof layer formed on the outer wall of the concrete structure in order to prevent moisture from penetrating into the concrete structure and damaging the concrete structure A protective material for protecting, comprising: an adhesive layer (110) formed to abut a waterproof layer; A nonwoven fabric layer 140 formed on the adhesive layer 140; And a hollow plate layer 150 positioned on the nonwoven fabric layer. The hollow plate 150 may reduce the pressure applied by the gypsum-mixed gypsum.

Specifically, the composite panel sliding protecting material is formed on the outside of the waterproof layer when the waterproofing is performed on the outer side of the structure, and the soil and the concrete mixed with the soil or the pebble are put on the outer surface of the hollow panel of the composite panel sliding protecting material, Can be completed. At this time, the soil, gravel-mixed soil, cement mixture, concrete mixture, etc., which are put in the finishing work, smoothly slides downward by gravity along the surface of the hollow plate layer formed on the outermost side of the composite panel sliding protection material, It is possible to prevent the damage to the protective material itself and to protect the waterproof layer which is intended to protect the protective material by reducing the transfer to the entire waterproof layer and the composite panel sliding protective material.

Further, the composite panel sliding protection member is formed below the adhesive layer as shown in FIG. 3 for further improving the dew condensation preventing property and the heat insulation performance, and a foam layer 130 for absorbing external impact and preventing heat transmission Or a foam layer 130 may be formed instead of the nonwoven fabric layer 140 as shown in FIG.

More specifically, the adhesive layer 110 is for bonding the waterproof layer and the composite panel sliding protecting material to each other. The adhesive layer 110 may be formed of a material having a high adhesion to the waterproof layer Excellent adhesion and excellent sealing ability, so that penetration of water can be almost completely prevented.

Therefore, the adhesive layer 110 is not particularly limited as long as it can generally adhere and attach different objects such as a double-faced tape, a silicone release adhesive, a bituminous rubber, an asphalt adhesive, The release film 120 is removed and the waterproof layer and the adhesive layer 110 are removed immediately before the moisture barrier layer 120 is attached to the waterproof layer. And the release film may be used without limitation as long as it can be easily attached and detached without damaging the adhesive layer. For example, a polyethylene film can be used.

On the other hand, the release film 120 protects the adhesive force of the adhesive layer when a plurality of protective materials are laminated or superimposed on each other during transportation / storage of the composite panel sliding protection material having improved dew condensation preventing property and heat insulating performance of the present invention, Can be prevented.

The nonwoven fabric layer 140 formed on the adhesive layer 110 is not particularly limited as long as it is a generally used nonwoven fabric. Preferably, a plurality of synthetic resin films are formed adjacent to each other in the longitudinal direction. to be formed by weaving intersecting a plurality of synthetic resin films in a vertical direction, and the synthetic resin film is polyethylene film, and / or poly-polypropylene is used a polypropylene film, or more preferably ^{20 g / m 2 ~ 250 g} / m 2 ( PP) and polyethylene (PE) may be used.

The hollow plate layer 150 formed on the outermost surface of the composite panel sliding protection material formed on the nonwoven fabric layer 140 and improved in the dew condensation preventing property and the heat insulating performance of the present invention, By reducing the pressure, the protective material and the protective material can protect the waterproof layer to be protected.

As shown in FIG. 1, the conventional waterproof layer protecting material formed by adhering to the outer surface of the waterproof layer due to soil or gravel-mixed soil that is settled during the operation of troweling or pressing concrete, which is one of finishing work of waterproof construction, That is, the waterproof layer may be detached from the outer wall of the concrete structure due to dragging and dropping of the waterproof layer adhered to and adhered to each other by the adhesive layer or the adhesive, or the waterproof layer may be damaged.

However, in the case of the composite panel sliding protecting material having improved dew condensation prevention and heat insulation effect of the present invention, it is possible to prevent the occurrence of the above-mentioned voids, such as soil, gravel-mixed soil, cement mixture and concrete mixture, The protection material and the waterproof layer can be protected by gravity downwardly by gravity along the surface of the waterproof layer, and resistance against the pressure settled by gravity as time elapses after the application of the waterproof layer improves the durability of the waterproof layer .

Specifically, the hollow plate layer 150 is made of a rigid material containing at least one member selected from the group consisting of polypropylene, polyethylene phthalate, polyacrylic, polymethylmethacrylic acid, and gypsum, A plate-like structure formed with a diaphragm, or a double-panel structure having a diaphragm formed therein.

For example, the diaphragm may be arranged at regular intervals in the hollow space of the hollow plate layer 150, and the diaphragm may be uniformly arranged in the transverse direction or the longitudinal direction, or may be formed in the transverse direction and the longitudinal direction, And the diaphragm may preferably be arranged in a lattice inside the hollow plate layer.

The space formed in the hollow plate layer serves as a buffer against an external impact and may contain an air layer to block heat exchange of the concrete structure. Specifically, the hollow plate layer can prevent tearing or damage of the outermost layer of the waterproof layer protection material due to rough or sharp foreign matter or friction of the earth and concrete, which can be incorporated when the soil is backed up or poured into concrete due to a hard material, The hollow space formed in the hollow plate layer absorbs impact energy corresponding to physical impact transmitted from the outside to minimize the impact transmission to the waterproof layer, thereby improving the durability of the waterproof layer.

In addition, when the protective material is vertically attached due to the diaphragm formed inside, the vertical resistance and the upright retention force are improved, so that it is not bent or warped, and the waterproofing finishing work is performed when the soil is backed up or pressed. It can have resistance to the settlement pressure that occurs naturally.

Further, since the air layer is formed by the air contained in the space formed in the hollow plate layer 150, it is possible to prevent the cooling air and heat from being transmitted to the inside of the concrete structure from being transferred to the inside or to lose the internal temperature of the concrete structure to the outside It is possible to prevent condensation and improve the heat insulating effect.

Preferably, the width between the diaphragms may be 1: 0.1 to 2 ratio as compared to the thickness of the hollow plate layer 150, and when the ratio is out of the range, the diaphragm may not have sufficient vertical resistance and upright holding force, The resistance may be weakened or a sufficient air layer may not be formed, thereby preventing condensation and insulating effect.

3, a foam layer 130 may be further interposed between the nonwoven fabric layer 140 and the adhesive layer 110 to improve the dew condensation prevention effect and the heat insulating effect of the present invention. The foam layer 130 and the non- (140) may be bonded to each other with an adhesive layer (111).

Specifically, the foam layer 130 may be formed of a foam formed by foaming and dispersing the polymer in a gas tightly. The foam layer 130 is preferably formed of polyethylene, polyurethane, ethylene vinyl acetate, polyvinyl chloride, polyurea, and polystyrene The foam layer may be formed by foaming at least one polymer selected from the group consisting of polypropylene, polypropylene, and polypropylene, and more preferably a laminate of a single layer or a plurality of foam layers to form a foam layer having a thickness of 10 to 30 mm.

If the thickness of the foam layer 130 is thin, it can not prevent the heat transfer inside the outer layer, thereby preventing the dew condensation and the heat insulation effect. If the foam layer 130 is thick, the load increases to decrease the adhesive force, Not only the economical efficiency is lowered but also the amount of the ground which is equal to the thickness of the protective material is required when the concrete structure is constructed and the construction cost is increased accordingly.

Meanwhile, the foam layer 130 absorbs shocks applied from the outside due to a minute cell formed therein and prevents external cold air and heat from penetrating into the concrete structure, thereby preventing condensation and insulating effect , When the foaming layer is formed by foaming using a polymer, the foaming ratio reaches 20 to 40 times, which is advantageous in lightness.

Therefore, by adhering the composite panel sliding protecting material with improved dew condensation prevention and adiabatic effect to the outer surface of the waterproof layer, it is possible to protect the waterproof layer from external pressure or impact that may occur at the subsequent process or after completion of the construction, It is possible to prevent the internal and external heat exchange and to prevent condensation and to provide a thermal insulation effect.

In the case of a composite panel sliding protecting material having improved dew condensation prevention and adiabatic effects in the present invention, it may further comprise a fixing member for more firmly fixing the waterproof layer and the protective material and / or between the nonwoven fabric layer and the hollow plate layer, Is not particularly limited as long as it is a member used for fixing and bonding between two commonly known objects such as an adhesive tape and an adhesive, and is preferably used as a waterproof layer and a waterproof layer by using a selected one of pins, nails, anchor- The protective material can be fixed, and more preferably, it can be fixed using nails.

However, when a nail is used as a fixing member, the object can be firmly fixed between the two objects by penetrating and fixing the object, but there is a fear that the waterproof layer formed on the inside of the protection material may be damaged due to the pointed portion of the nail.

Therefore, a gel type adhesive layer can be further formed between the waterproof layer and the adhesive layer, and the fixing member penetrates the portion where the adhesive layer is formed to fix the waterproof layer and the protection material to each other, thereby preventing the waterproof layer from being damaged by the adhesive layer Or if the waterproof layer is damaged, the damaged portion can be reinforced or repaired due to the adhesive layer.

The adhesive layer is not particularly limited as long as it is a gel-type material having a tacky component and has an effect of blocking cracks, holes or voids due to high tackiness. However, it is preferable to use asphalt, process oil, High modulus mastic asphalt compounds containing modifiers, adhesion promoters, etc. may be used.

On the other hand, the composite panel sliding protective material having improved dew condensation prevention and adiabatic effects of the present invention can preferably protect the waterproof layer formed on the exterior of the concrete structure, but is not limited thereto. It can be used by attaching it to the outside of the material of the kind and kind.

The foam layer 130 may be formed between the adhesive layer 110 and the hollow plate layer 150 instead of the nonwoven fabric layer 140 formed on the adhesive layer 110 as shown in FIG. The hollow plate layer 150 and the foam layer 130 may be formed of the same components as the adhesive layer 140 and bonded to each other. Preferably, the hollow plate layer 150 and the foam layer 130 And the foam layer 130 can be exerted with a desired bonding force and sealing force in a state where the hollow plate layer 150 and the foam layer 130 are in close contact with each other, Available.

More specifically, it can be performed by any one or more selected from the group consisting of arc welding, resistance welding, ultrasonic welding, heat welding, and high frequency laser welding, Considering the foam layer 130, it is preferable to use a high-frequency laser welding capable of performing fine welding or a heat welding method capable of bonding without using an additional adhesive.

In particular, in comparison with other welding methods, the high frequency laser welding method not only reduces the thermal distortion due to a small energy transfer to the foam layer 140 and the hollow plate layer 150 at portions other than the working portion during the welding operation, It is possible to remarkably reduce the possibility of peeling in the waterproof layer protective material due to the excellent adhesive force, thereby improving the durability.

For example, CW having When using a high-frequency laser welding method and laser energy density of 250 kJ / cm ² to ^{1 MJ / cm 2 (laser energy} density) in order to bond the hollow pancheung 150 and foam layer 130 ( a continuous wave high frequency laser and an optical system, and more specifically, a CW high frequency laser having a laser energy density of 300 kJ / cm ² to 500 kJ / cm ² And an optical system at a welding speed of 80 to 120 mm / s.

In addition, when welding is performed using a CW high-frequency laser in welding, the laser oscillation can be modulated to have a constant frequency in order to prevent thermal damage of the welding material due to the heat continuously exposed. In this case, 100 Hz to 1 kHz, and the rate at which the laser oscillates during modulation may be 30% to 90% of the modulation frequency. For example, when a 50% oscillation rate is used for 1 kHz modulation, laser output modulation is performed at 1 ms intervals, 500 us is a state in which the laser oscillates, and 500 us is a state in which laser oscillation is not performed State is repeated.

On the other hand, the composite panel sliding protective material having improved dew condensation prevention and adiabatic effects of the present invention can preferably protect the waterproof layer formed on the exterior of the concrete structure, but is not limited thereto. It can be used by attaching it to the outside of the material of the kind and kind.

For example, the composite panel sliding protection material of the present invention has improved dew condensation prevention and thermal insulation effects, including a waterproof layer formation step of forming a waterproof layer on the outer wall of the concrete structure; Attaching a composite panel sliding protecting material having improved anti-condensation and heat insulating effect to the outer wall of the concrete structure in which the waterproof layer is formed; A fixing step of bonding between the waterproof layer and the protection material; And a finishing step of subjecting the outer surface of the protective material to soil-backed or pressed concrete work.

The waterproof layer to be applied to the concrete structure is not particularly limited and can be generally used widely. For example, it may be a waterproof sheet including an asphalt coating waterproofing material.

More specifically, the present invention provides a waterproofing method using a composite panel sliding protecting material having improved dew condensation prevention and adiabatic effects, comprising: forming a waterproof layer on the concrete structure; separating a release film of a plurality of protective materials; It is possible to fix the waterproof layer and the protection material through a fixing member passing through the protection material.

At this time, the composite panel sliding protective material having improved dew condensation prevention and adiabatic effect of another contemporary design, which is formed adjacent to the composite panel sliding protective material, is usually formed by using an adhesive tape, tacker, stamper, A fixing member for penetrating the protection material and fixing the waterproof layer and the protection material should penetrate the portion where the adhesive layer formed on one side of the protection material is formed and the adhesive layer is formed on the upper end, .

After the protective material is applied, the concrete structure is laid on the bottom surface of the concrete structure, and when the surface is the wall surface, the soil is backfilled with a mixture of sand, soil and rubble, .

More specifically, when the concrete and the soil contact with the protective material, the friction force is reduced to a smooth part of the surface to induce a sliding phenomenon, so that it slips near the floor. Therefore, the protection material is prevented from being damaged firstly, Can be prevented from being damaged.

In addition, due to the settlement pressure that occurs naturally as time elapses after the application of the soil sand backing or pressing concrete, the existing waterproofing layer protection material 20 is pushed together and attracts the waterproof layer 10 together with the waterproof layer Durability can be reduced because the waterproof layer 10 can no longer be protected even if only the existing waterproof layer protection material 20 is pushed down. However, in the case of the composite panel sliding protection material having improved dew condensation prevention and heat insulation effect of the present invention The secondary waterproof layer and the protection material can be prevented from being damaged by preventing the secondary waterproof layer from flowing down or bending by being separated from the waterproof layer by resistance to the subsidence load due to the hollow plate layer formed on the outermost surface.

The present invention is not limited to the above-described specific embodiments and descriptions, and various modifications can be made to those skilled in the art without departing from the scope of the present invention as claimed in the claims. , And such modifications are within the scope of protection of this invention.

First, solid polyethylene and powdered azodicarbonamide type foaming agent were mixed using a dry mixer and then extruded by transfer to a T-die in a state of being melted (220 to 250 ° C) And foamed to a thickness of 5 mm to form a foam. Then, the foams were adhered to each other using an adhesive to form a foam layer having a total thickness of 20 mm.

One surface of the foamed layer was coated with an adhesive to form an adhesive layer, and then a release film was attached. A nonwoven fabric was adhered to the other surface of the foamed layer on the side to which the release film was adhered using an adhesive to prepare a sheet.

A hollow plate was prepared by using a polypropylene board produced by extrusion molding polypropylene having diaphragms arranged such that a 4 x 4 mm grid was formed inside the 4 mm thick.

A waterproof layer is formed by adhering a rubberized asphalt adhesive composite sheet (AHA Waterproof Co., Ltd.) to an outer wall surface of a concrete structure, and then a release film is removed from the sheet to prevent a space from being formed along the surface layer surface of the waterproof layer A plurality of sheets were adjacently attached. At this time, the adjacent portion was sealed with a spacing space formed at an adjacent portion between sheets using an adhesive tape.

After removing the protective film of the attached sheet, the hollow plate layer produced on the outer surface of the sheet was attached by laser welding to form a composite panel sliding protecting material of the present invention.

The waterproof layer and the protection material were fixed by using nails on the outer surface of the constructed composite panel sliding protection material, and then the soil was mixed with the gravel mixed with sand, soil, and stones.

0.3 liters of water and 1.0 kg of ice were filled in a stainless steel rectangular barrel, and a plastic dish was placed under the conditions of relative humidity 80% and temperature 40 ° C under the conditions of Example 1 and Comparative Examples 1 to 6. Then, The amount of water poured into the dish from a square cup was measured in units of 0.1 g to measure the effect of preventing condensation.

As shown in Table 2, no condensation occurred during the initial 0.5 hour, and condensation was observed in Comparative Examples 1, 3, 5, and 6 as time elapses.

It was confirmed that the condensation phenomenon was prevented by blocking the outside cold air due to the foam layer and the hollow plate layer having a predetermined thickness or more.

However, in the case of Comparative Example 6, the thickness of the foamed layer and the hollow plate layer was the same as Example 1, but after 3 hours, it was confirmed that 0.2 g of condensed water was present. Since there is no space containing air due to absence of diaphragm, It was confirmed that the effect of preventing dew condensation was lower than that of Example 1 in Comparative Example 6 in which the diaphragm was formed in a horizontal shape.

[Experimental Example 2]

Adhesion evaluation

The adhesive strength was measured using a universal tensile tester after attaching Example 1 and Comparative Examples 1 to 6 to the wall surface, respectively. When the tensile bond strength is less than 20 Kgf / 5 cm ² , it is defective. When the tensile bond strength is less than 20 Kgf / 5 cm ² , it is unsatisfactory. When the tensile bond strength is 30 Kgf / 5 cm ² or more,

In Comparative Example 7, a waterproof layer protective material was formed by using a sheet and a hollow plate layer prepared in the same manner as in Example 1, except that the foam layer and the hollow plate layer were adhered using a general adhesive, not by laser welding Respectively.

The results of Table 3 indicate that the adhesive properties of Example 1 and Comparative Examples 1, 3, 5, and 6 were superior in tensile adhesion strength of 30 Kgf / 5 cm ² or more and in Comparative Examples 2 and 4 It was confirmed that the adhesion was insufficient due to the increase in the load due to the thick thickness.

In the case of Comparative Example 7 in which a hollow plate layer and a foamed layer were adhered with a general adhesive, before the wall surface and the waterproofing layer protective material of Comparative Example 7 were peeled off, the hollow plate layer and the foamed layer were first peeled off and the tensile strength was measured to be lowest .
