<이중 폴리염화비닐 방수용 시트><Double polyvinyl chloride waterproof sheet>
본 발명의 이중 폴리염화비닐 방수용시트(200)는 도2a와 같이 재료적성질이 다른 폴리염화비닐 방수시트가 적층된 구조로 되어 있다.The double polyvinyl chloride waterproof sheet 200 of the present invention has a structure in which polyvinyl chloride waterproof sheets having different material properties are stacked as shown in FIG. 2A.
즉 신재의 폴리염화비닐 방수시트(210) 위에 재생 폴리염화비닐 방수시트(220)이 서로 적층되어 있다.That is, the recycled polyvinyl chloride waterproof sheet 220 is stacked on each other on the new polyvinyl chloride waterproof sheet 210.
상기 재생 폴리염화비닐 방수시트(220)는 폐 폴리염화비닐수지 70 내지 80 중량%, 폐 아세트산비닐공중합체 접착필름 스크랩을 재활용한 재생수지 14 내지 10 중량%, 폐 아세트산비닐공중합체 접착제를 재활용한 재생수지 8 내지 5 중량%, 석분 8 내지 5 중량%로 한정된다.The recycled polyvinyl chloride waterproof sheet 220 is 70 to 80% by weight of waste polyvinyl chloride resin, 14 to 10% by weight of recycled resin to recycle waste vinyl acetate copolymer adhesive film, recycled waste vinyl acetate copolymer adhesive It is limited to 8 to 5% by weight of recycled resin and 8 to 5% by weight of stone powder.
이는 재생 폴리염화비닐 방수시트(220)가 소요 인장강도 및 신장율(시험방법은 KS F 4911(합성 고분자계 방수 시트)에 명시 되어있는 인장성능)을 만족하도록 실험을 통해 한정된 (아래 표1참조) 구성비임과 동시에,This is because the recycled polyvinyl chloride waterproof sheet 220 is limited through experiments to satisfy the required tensile strength and elongation rate (the tensile performance specified in KS F 4911 (synthetic polymer waterproof sheet)) (see Table 1 below). At the same time as the construction cost,
도막방수재(아크릴산에스테르계 도막방수재로서 「극동크리트 #3010」을 사용)와의 접합력이 KS F 4917의 기준(방수시트 간의 접합성능은 5.1 kgf/cm 이상)을 상회(아래 표2참조)하는 구성비이다.Bonding strength with coating waterproofing material ("Far East Crete # 3010" is used as acrylic ester-based coating waterproofing material) is higher than KS F 4917 standard (bonding performance between waterproof sheets is 5.1 kgf / cm or more) (see Table 2 below). .

신재 폴리염화비닐 방수시트(210)는 통상적으로 판매되는 폴리염화비닐 방수시트를 사용한다. The new polyvinyl chloride waterproof sheet 210 uses a polyvinyl chloride waterproof sheet that is commonly sold.
신재의 폴리염화비닐 방수시트는 상기 재생 폴리염화비닐 방수시트(220)에 비하여 내후성, 콘크리트와 같은 바탕체(100)와의 접착력, 치수안정성 및 인장강도가 뛰어나기 때문에 본 발명에서는 상기 바탕체와 접하는 부분은 신재 폴리염화비닐 방수용시트를 사용하되, 그 두께는 상술한 재생 폴리염화비닐 방수시트 보다 작게 형성시킨다. 그 두께의 비는 전체두께가 결정되면 재생 폴리염화비닐 방수시트: 신재 폴리염화비닐 방수용시트가 두께의 비가 5-6:1이 되도록 함이 경제적인 관점 및 신재 폴리염화비닐 방수용시트를 사용하는 목적 상 바람직하다.The new polyvinyl chloride waterproof sheet is excellent in weather resistance, adhesion to the substrate 100, such as concrete, dimensional stability and tensile strength compared to the regenerated polyvinyl chloride waterproof sheet 220 in the present invention, the part in contact with the substrate is Using a new polyvinyl chloride waterproof sheet, the thickness is made smaller than the recycled polyvinyl chloride waterproof sheet described above. The ratio of the thickness is the recycled polyvinyl chloride waterproof sheet: the new polyvinyl chloride waterproof sheet has a thickness ratio of 5-6: 1 when the total thickness is determined. Phase is preferred.
단지 이음부에 사용되는 이중 폴리염화비닐 방수용시트 위에 별도의 신재인 보강 폴리염화비닐시트(300)를 도2b와 같이 별도로 부착하게 되므로 전체두께는 이음부 이외의 경우보다 절반 이하로 함이 바람직하며, 이음부의 경우에는 시트간 결합에 의하여 부착성능 및 인장강도가 떨어지게 되므로 재생 폴리염화비닐 방수용시트 대 신재 폴리염화비닐 방수용시트의 두께의 비를 1: 5-6의 비율로 형성시키는 것이 바람직하다. 즉 이음부의 경우에는 신재 폴리염화비닐 방수시트(210)의 두께를 재생 폴리염화비닐 방수시트(220) 두께보다 크게 하고, 전체 두께(재생 폴리염화비닐시트 + 신재 폴리염화비닐시트)는 이음부 이외의 경우보다 1/2이하로 형성시켜 이음부에 설치되는 이중 폴리염화비닐 방수용시트에 단차가지지 않도록 한다. Since the reinforcement polyvinyl chloride sheet 300, which is a separate new material, is separately attached to the double polyvinyl chloride waterproof sheet used for the joint part as shown in FIG. 2B, the total thickness is preferably less than half than that of the case other than the joint part. In the case of the joint, the adhesion performance and the tensile strength are reduced by the bonding between the sheets, so it is preferable to form a ratio of the thickness of the recycled polyvinyl chloride waterproof sheet to the new polyvinyl chloride waterproof sheet in a ratio of 1: 5-6. That is, in the case of the joint, the thickness of the new polyvinyl chloride waterproof sheet 210 is greater than the thickness of the regenerated polyvinyl chloride waterproof sheet 220, and the overall thickness (regenerated polyvinyl chloride sheet + new polyvinyl chloride sheet) is other than the joint portion. It is formed to less than 1/2 than the case so as not to have a step on the double polyvinyl chloride waterproof sheet installed in the joint.
상술한 이음부 및 이음부 이외의 재생 폴리염화비닐 방수시트 대 신재 폴리염화비닐 방수시트 두께의 비는 전체 방수층의 두께, 소요 인장강도의 기준 등에 따라 변경될 수 있다.The ratio of the thickness of the regenerated polyvinyl chloride waterproof sheet to the new polyvinyl chloride waterproof sheet other than the above-described joints and joints may be changed according to the thickness of the entire waterproof layer, a criterion of required tensile strength, and the like.
상술한 재생 폴리염화비닐 방수시트(220) 및 신재 폴리염화비닐 방수시트(210)는 서로 압축기에 의하여 압착되어 제조됨으로서 본 발명의 이중 폴리염화비닐 방수용시트(200)가 완성된다. The above-mentioned recycled polyvinyl chloride waterproof sheet 220 and the new polyvinyl chloride waterproof sheet 210 are manufactured by pressing each other by a compressor, thereby completing the double polyvinyl chloride waterproof sheet 200 of the present invention.

본 발명에 의한 복합방수공법의 일 실시예를 단계적으로 설명하면 다음과 같다.When explaining step by step an embodiment of the composite waterproof method according to the present invention.
1) 바탕면의 정리 및 보수 보강 : 1) Cleanup and reinforcement of the base surface:
콘크리트 바탕체(100)의 노후화에 의한 파손부위나 시트에 손상을 가할 수 있는 이물질을 제거한다. 균열 취약부위 및 모르타르 제거부위에 침투성 모체 강화제를 도포한다. 바탕면이 특히 낮은 곳은 방수강화 모르타르로 평탄하게 마감한다. Removes foreign substances that may damage the damage site or the sheet due to the aging of the concrete substrate 100. Apply permeable parent reinforcement to crack fragile areas and mortar removal areas. Particularly low ground surface should be finished with waterproof mortar.
2) 시트 접착제(방수접착제) 도포 :2) Application of sheet adhesive (waterproof adhesive):
본 발명의 방수접착제는 통상의 접착제와는 달리 방수제 성분이 포함된 것을 이용한다. 즉 시트 접착제로서 기본적으로 시트를 바탕체(100)에 부착시키는 기능 이외에 방수재로서 기능을 가지도록 방수제 성분을 부가시킨 방수접착제를 이용함에 특징이 있다.Unlike the conventional adhesive, the waterproof adhesive of the present invention uses a water-containing adhesive. That is, as a sheet adhesive, in addition to the function of basically attaching the sheet to the base 100, it is characterized in using a waterproof adhesive added with a waterproofing agent component to have a function as a waterproofing material.
방수접착제의 경우 수용성 아크릴 접착제로서 내수성을 강화시키기 위해 총 중량에 대하여 40 내지 50중량%의 물, 30-40중량%의 아크릴산에스테르, 10-15중량%의 메타아크릴산에스테르, 5-10중량%의 그리시딜아크릴산, 3-5중량%의 계면활성제 및 필러(FIILLER) 5-10중량%의 조성비율을 가지는 것이 바람직하다.Water-resistant adhesives are water-soluble acrylic adhesives with 40-50% by weight of water, 30-40% by weight of acrylic acid esters, 10-15% by weight of methacrylic acid esters, 5-10% by weight, to enhance water resistance. It is preferred to have a composition ratio of glycidyl acrylic acid, 3-5 wt% surfactant and 5-10 wt% filler (FIILLER).
이중 폴리염화비닐 방수용시트(200)를 부착해야할 면에 방수접착제를 얇고 균일하게 도포한다.The waterproof adhesive is applied thinly and uniformly to the surface to which the double polyvinyl chloride waterproof sheet 200 is to be attached.
3) 이중 폴리염화비닐 방수용시트 포설 :3) Installation of double polyvinyl chloride waterproof sheet:
이중 폴리염화비닐 방수용시트(200)는 공장에서 소정의 폭과 두께로 제작된 롤(ROLL) 형의 제품을 사용한다. 이중 폴리염화비닐 방수용시트(200)는 현장 여건에 맞추어 가급적 이음매가 적게 발생하도록 재단하여 바닥에 잘 밀착시킨 다음 굴림판 등을 이용하여 시트면을 힘있게 눌러준다.Double polyvinyl chloride waterproof sheet 200 uses a product of a roll (ROLL) type manufactured in a predetermined width and thickness at the factory. Double polyvinyl chloride waterproof sheet 200 is cut in accordance with the site conditions as possible to reduce the seam as possible to closely adhere to the floor and then press the sheet surface by using a rolling plate.
시트(200)와 시트(200)의 이음부위는 도3b와 같이 시트의 이음면이 서로 맞대어지게 포설하되 연결부위는 용착제(PVC SEAM SEALER)를 주입시킨다. 열풍용접기를 이용하는 것과 비교하여, 본 발명에서는 일종의 실링재인 용착제를 이음부에 주입시킴으로서 별도의 장치없이도 이음부 설치작업이 가능한 장점이 있다. The joints of the seat 200 and the seat 200 are installed so that the joint surfaces of the seats face each other as shown in FIG. 3B, but the joint part is injected with a PVC SEAM SEALER. Compared to using a hot air welder, in the present invention, by injecting a welding agent, which is a kind of sealing material, into the joint, there is an advantage in that the joint can be installed without a separate device.
4) 보강 폴리염화비닐시트(300) 부착 :4) Attach the reinforced polyvinyl chloride sheet 300:
상기 보강 폴리염화비닐시트는 이중 폴리염화비닐 방수용시트(200)의 이음부에 사용하는 것으로서, 신재 폴리염와비닐 시트를 이용한다. 보강 폴리염화비닐 시트는 방수용시트(200)보다 얇은 두께로도 충분하다.The reinforcing polyvinyl chloride sheet is to be used at the joint portion of the double polyvinyl chloride waterproof sheet 200, and new polyvinyl chloride and vinyl sheet are used. Reinforcement polyvinyl chloride sheet is sufficient to be thinner than the waterproof sheet (200).
도4b와 같이 시트(200)와 시트(200)의 이음부위는 보강 폴리염화비닐 시트를 시트(200) 간의 이음매와 보강 폴리염화비닐 시트의 중앙선이 일치하도록 설치한 후 용착제를 이용하여 접착한다.As shown in FIG. 4B, the joint portions of the sheet 200 and the sheet 200 are bonded to each other using a adhesive after installing the reinforced polyvinyl chloride sheet so that the seam between the sheets 200 and the center line of the reinforced polyvinyl chloride sheet are coincident with each other. .
본 발명에서 이음부는 되도록 신재 폴리염화비닐 시트를 사용토록 하며 이음부위에서 되도록 단차가 지지 않도록 하는 방식을 택하고 있다.In the present invention, the joint part is to use a new polyvinyl chloride sheet as possible, and the method is selected so that the step is not so as to be possible at the joint part.
통상의 시트 이음부는 도4a와 같이 서로 겹칩이음을 한다. 따라서 겹쳐진 부위에 위로 볼록하게 돌출되고, 내부에는 빈공간이 형성되게 되는데 이는 방수성능에 상당한 악영향을 미치게 되며, 이음부를 서로 겹치게 형성시키는 경우 되도록 이음부를 적게 형성시키기 위해 면적이 큰 시트를 사용하기 마련인데, 큰 시트는 무게가 무겁고 면적도 클 수밖에 없어 한쪽 면에 일정한 면적으로 균일하게 겹치게 하는 작업이 용이하지 않다. 또한 이음부위라고 해서 두께가 다른 시트를 이용하지 않아 필연적으로 이음부는 위로 돌출되어 형성될 수 밖에 없어 방수시트가 평탄성을 유지하기가 매우 어렵다는 문제점이 있다.Normal sheet joints are stacked together as shown in Fig. 4A. Therefore, it protrudes convexly upward on the overlapped area, and there is a void space formed therein, which has a significant adverse effect on the waterproof performance, and in order to form joints with a large area in order to form joints overlapped with each other, a large sheet is used. Although large sheets are heavy and have a large area, it is not easy to uniformly overlap one surface with a certain area. In addition, since the joints do not use sheets having different thicknesses, the joints are inevitably formed to protrude upward, and thus there is a problem in that the waterproof sheet is very difficult to maintain flatness.
이에 본 발명에서는 바탕면(100)과 시트(200)간에 빈 공간이 형성되지 않도록 맞댄 이음방식을 택하고, 이음부위의 시트(200)는 두께를 이음부 이외의 두께보다 작게 형성시키는 방식을 택하고 있으며, 보강 폴리염화비닐시트(300)도 되도록 얇게 형성된 것을 이용하여 전체두께가 겹친이음의 경우보다 작게 형성시킨다는데 특징이 있다. 즉 이음부에서의 하자요인을 없애는 방식을 취하고 있다. Accordingly, in the present invention, a back joint method is adopted so that an empty space is not formed between the base surface 100 and the sheet 200, and the seat 200 of the joint portion is selected to have a thickness smaller than the thickness other than the joint portion. The reinforcement polyvinyl chloride sheet 300 may be formed to be smaller than the case where the entire thickness is overlapped by using a thinner one. In other words, it takes a way to eliminate the defects in the joint.
나아가 보강 폴리염화비닐시트의 가장자리와 주변 시트 부위에 고탄성 크랙씰(CRACK-SEAL)을 바르고 화이버글래스(FIBERGLASS) 등의 보강포(310)를 부착하여 이음부위에 각이 생기지 않도록 하고 이음부위의 접착을 보강한다.Furthermore, high elastic crack seal (CRACK-SEAL) is applied to the edge of the reinforced polyvinyl chloride sheet and the surrounding sheet area, and a reinforcement cloth 310 such as fiberglass is attached to prevent the angle from forming at the joint part and adhesion of the joint part. Reinforce.
5) 탈기반 설치 :5) Debase installation:
탈기반의 성능에 따라 계산된 소요 개소의 탈기반을 탈기반의 시공방법에 따라 설치한다. The debases of the required parts calculated according to the debasement performance are installed according to the debasement construction method.
6) 도막방수재(400)의 1차 도포 :6) Primary coating of the coating waterproofing material 400:
아크릴산에스테르계 도막방수재(400)를 혼합하여 붓이나 로울러를 이용하여 균일하게 도포한다. 이 때 사용하는 도막방수재는 KS F 4919 기준에 적합한 제품을 사용한다.Acrylic ester-based coating waterproofing material 400 is mixed and uniformly applied using a brush or roller. In this case, the waterproofing material used shall be a product conforming to KS F 4919 standard.
7) 도막방수재(400)의 2차 도포 :7) Secondary coating of the coating waterproofing material 400:
1차 도포된 도막이 양생된 후 2차 도포한다. 시공방법은 1차 도포와 동일하나 도포방향을 1차 도포 시의 방향과 교차되게 한다.After the first applied coating film is cured, the second coating is applied. The construction method is the same as the primary coating, but the application direction is crossed with the direction during the primary application.
8) 도막보호마감재(TOP COATING)(500)의 도포8) Application of Top Coating 500
2차 도포된 도막이 양생된 후 도막보호마감재(500)를 얇고 균일하게 도포하여 방수시공을 마무리한다.After the second coating film is cured, the coating protective film 500 is applied thinly and uniformly to finish the waterproof construction.
비노출공법으로 시공하는 경우 상기 도막보호마감재(500)의 도포를 생략하고 누름 콘크리트 또는 보호 모르타르로 마감할 수도 있다.In the case of a non-exposure method, the coating of the protective film 500 may be omitted and finished with pressed concrete or protective mortar.
본 발명의 이중 폴리염화비닐 방수용시트에 의해 종래의 방수용 시트는 도막방수재가 도포되는 부위는 별도의 부칙포 층이 없이도 접착될 수 있는 재료적 성질을 가지는 재생 폴리염화비닐 방수용시트를 사용하고, 재생 폴리염화비닐 방수용시트 아래에 신재 폴리염보비닐 방수용시트를 형성시킴으로서 바탕체와의 부착 및 인장강도의 확보가 가능하며, 방수접착제를 이중 폴리염화비닐 방수용시트와 바탕체의 결합에 이용함으로서 접착기증 외에 방수성능을 부가하여 확복할 수 있으며, 시트 사이의 이음부에 단층이 지지않도록 하면서 균일하게 이음부를 처리할 수 있어 작업성이 향상된다. 또한 폐 폴리염화비닐수지를 사용함으로 환경친화적 제조방법을 제공하며 시공 시 발생하는 폐재도 다시 재활용이 가능하며 이중 폴리염화비닐 방수용시트)와 도막방수재를 결합한 복합방수공법은 시트 자체로 도막방수재와의 접착력을 갖추고 있는 만큼 종래의 복합방수공법에 비해 시공성과 경제성이 뛰어나고, 종래 시트방수공법에서 주요한 방수사고로 제기되는 이음접합상의 문제를 더한층 획기적으로 해결하여 신뢰성 높은 방수층을 제공할 수 있다. By using the double polyvinyl chloride waterproof sheet of the present invention, the conventional waterproof sheet is a recycled polyvinyl chloride waterproof sheet having a material property that can be adhered to a portion to which the coating waterproofing material is applied, without a separate buoy layer. By forming a new polyvinyl chloride waterproof sheet under the polyvinyl chloride waterproof sheet, it is possible to attach to the base body and secure tensile strength. It can expand and expand, and it can process a joint uniformly, without preventing a single layer from joining to the joint between sheets, and workability improves. In addition, waste polyvinyl chloride resin is used to provide an environmentally friendly manufacturing method, and waste materials generated during construction can be recycled again. It is excellent in workability and economical efficiency as compared with the conventional composite waterproofing method, as well as adhesive strength, and can solve the problem of the joint joint caused by the major waterproof accident in the conventional sheet waterproofing method to further provide a reliable waterproof layer.
