Description
본 발명은 PVC 수지 조성물 및 이를 이용한 내충격성이 우수한 PVC 엠보싱 방수시트 제조방법에 관한 것으로서, 보다 상세하게는, 재생PVC파우더, 메틸트리메톡시실란, 디페닐디에톡시실란 및 페닐트리클로로실란이 배합된 표면개질 재생PVC파우더 복합물에, 폴리에틸렌, 폴리프로필렌, 디옥틸프탈레이트, 카본블랙 및 스테아린산을 소정 온도에서 소정 시간 동안 용융하여 PVC 수지 조성물을 제조한 후 이를 성형 및 압착하여 내충격성이 우수한 PVC 엠보싱 방수시트를 제조할 수 있는 PVC 수지 조성물 및 이를 이용한 내충격성이 우수한 PVC 엠보싱 방수시트 제조방법에 관한 것이다.

건축 구조물, 예컨대 옥상이나 테라스 등을 방수 시공하는 방법 중에서 일반적으로 가장 많이 사용되는 것이 우레탄 방수 공법이다. Among the methods of waterproofing building structures, such as rooftops and terraces, the most commonly used method is the urethane waterproofing method.
우레탄 방수 공법은 점도가 높은 페인트와 같은 액상 물질을 칠하거나 고르게 펴서 하는 방법으로서, 그 시공방법이 복잡할 뿐만 아니라 시공 기간이 오래 걸리고 또한, 통상의 우레탄 방수 공법은 시공 후, 외기의 변화, 구조물의 신축 또는 균열 등에 따라 우레탄 도막이 갈라지거나 들뜨게 되어 본래의 방수 기능을 상실할 수 있으며, 따라서 시공 후에도 주기적으로 유지보수해야 하는 단점이 있다. The urethane waterproofing method is a method of applying or evenly spreading a liquid material such as high-viscosity paint. Not only is the construction method complicated, but the construction period is long. In addition, the normal urethane waterproofing method is used to prevent changes in external air and structures after construction. Due to expansion or cracking of the urethane coating, the urethane coating may crack or lift and lose its original waterproof function, which has the disadvantage of requiring periodic maintenance even after construction.
이와 같은 우레탄 방수 공법의 단점을 해소하기 위하여, 등록특허 제10-0949548호나 공개특허 제10-2017-0008345호 등에, PVC 방수시트를 이용한 PVC 방수시트 방수공법이 개발된 바 있다. In order to solve the shortcomings of such urethane waterproofing method, a PVC waterproofing sheet waterproofing method using PVC waterproofing sheet has been developed in Registered Patent No. 10-0949548 or Publication Patent No. 10-2017-0008345.
종래의 PVC 방수시트 방수공법은, 우레탄 방수 공법과 같이, 페인트를 사용하는 것이 아니라 시트(sheet)를 사용한다는 점에서 우레탄 방수 공법보다 상대적으로 간단하게 시공할 수 있고, 이에, 시공 기간 역시 짧은 장점을 갖는다. The conventional PVC waterproofing sheet waterproofing method, like the urethane waterproofing method, can be constructed relatively more simply than the urethane waterproofing method in that it uses sheets rather than paint, and thus has the advantage of having a shorter construction period. has
그러나 종래의 PVC 방수시트 방수공법은, PVC 방수시트가 강한 재질이 아니어서 외부 충격이 임계치를 초과할 경우 해당 부분이 찍히거나 찢어지면서 본래의 방수 기능을 상실하게 되는 문제점이 있다.However, the conventional PVC waterproof sheet waterproofing method has a problem in that the PVC waterproof sheet is not a strong material, so when an external impact exceeds a critical value, the relevant part is damaged or torn and the original waterproof function is lost.
따라서 옥상이나 테라스 등 사람의 출입이 잦은 곳에 PVC 방수시트 방수공법을 적용하려면 시공면에 모르타르를 시공하고 타일을 깔거나 데크를 먼저 설치해야 하는 등 추가적인 공정이 필요하다는 문제점이 있다. Therefore, in order to apply the PVC waterproof sheet waterproofing method to places where people frequently enter, such as rooftops or terraces, there is a problem that additional processes are required, such as installing mortar on the construction surface, laying tiles, or installing a deck first.
그리고 PVC 방수시트 방수공법을 적용할 때는 PVC 방수시트들 간의 접착이 중요한데, 현재는 접착용제를 사용하는 방법과 실링제를 사용하는 방법이 주류를 이루는 실정이다. And when applying the PVC waterproofing sheet waterproofing method, adhesion between PVC waterproofing sheets is important, and currently, the method of using adhesive solvent and the method of using sealing agent are mainstream.
하지만, 접착용제나 실링제를 사용해서 PVC 방수시트들을 접합시킬 경우, 시공은 간단할 수 있으나 시공 후 시간이 지남에 따라 그 접착 한계로 인해 접착력이 떨어지거나 접착부위가 탈리되는 단점이 있어 역시 잦은 유지보수를 필요로 한다는 점에서 이를 보완하기 위한 기술 개발이 필요한 실정이다. However, when joining PVC waterproof sheets using an adhesive solvent or sealant, construction may be simple, but as time passes after construction, there is a disadvantage in that the adhesive strength decreases due to the adhesion limit or the adhesive area detaches, which is also frequent. Given that maintenance is required, technological development is needed to supplement this.
따라서 본 발명의 목적은 재생PVC파우더, 메틸트리메톡시실란, 디페닐디에톡시실란 및 페닐트리클로로실란이 배합된 표면개질 재생PVC파우더 복합물에, 폴리에틸렌, 폴리프로필렌, 디옥틸프탈레이트, 카본블랙 및 스테아린산을 소정 온도에서 소정 시간 동안 용융하여 PVC 수지 조성물을 제조한 후 이를 성형 및 압착하여 내충격성이 우수한 PVC 엠보싱 방수시트를 제조할 수 있는 PVC 수지 조성물 및 이를 이용한 내충격성이 우수한 PVC 엠보싱 방수시트 제조방법을 제공하는 것이다. Therefore, the purpose of the present invention is to provide a surface-modified recycled PVC powder composite containing recycled PVC powder, methyltrimethoxysilane, diphenyldiethoxysilane, and phenyltrichlorosilane, polyethylene, polypropylene, dioctyl phthalate, carbon black, and stearic acid. A PVC resin composition capable of producing a PVC embossed waterproof sheet with excellent impact resistance by melting it at a predetermined temperature for a predetermined time to produce a PVC resin composition, and then molding and pressing it to produce a PVC embossed waterproof sheet with excellent impact resistance, and a method of manufacturing a PVC embossed waterproof sheet with excellent impact resistance using the same. is to provide.

본 발명의 바람직한 실시예에 따른 PVC 엠보싱 방수시트 제조방법은, 재생PVC파우더, 메틸트리메톡시실란, 디페닐디에톡시실란 및 페닐트리클로로실란이 배합된 표면개질 재생PVC파우더 복합물에, 폴리에틸렌, 폴리프로필렌, 디옥틸프탈레이트, 카본블랙 및 스테아린산이 첨가된 후 소정 온도에서 소정 시간 동안 용융되는 것을 통해 PVC 수지 조성물이 제조되는 단계와, 상기 제조된 PVC 수지 조성물이 공지의 카렌더링, 성형 및 압착 등의 공정을 통하여 PVC 엠보싱 방수시트로 제조되는 단계 등을 포함한다.The method of manufacturing a PVC embossed waterproof sheet according to a preferred embodiment of the present invention is a surface-modified recycled PVC powder composite containing recycled PVC powder, methyltrimethoxysilane, diphenyldiethoxysilane, and phenyltrichlorosilane, polyethylene, and polyester. Producing a PVC resin composition by adding propylene, dioctyl phthalate, carbon black, and stearic acid and then melting it at a predetermined temperature for a predetermined time; and the prepared PVC resin composition is subjected to known processes such as calendering, molding, and pressing. It includes the step of manufacturing a PVC embossed waterproof sheet through the process.
여기서, PVC 엠보싱 방수시트 제조방법은, 보다 바람직하게는, 재생PVC파우더, 메틸트리메톡시실란, 디페닐디에톡시실란 및 페닐트리클로로실란이 10:0.3:0.2:0.1의 부피비로 배합된 표면개질 재생PVC파우더 복합물 100 중량부에, 폴리에틸렌 20~40 중량부, 폴리프로필렌 10~30 중량부, 디옥틸프탈레이트 5~7 중량부, 카본블랙 3~5 중량부 및 스테아린산 2~4 중량부가 첨가된 후 200~250℃에서 3~5시간 용융되는 것을 통해 PVC 수지 조성물이 제조되는 단계와, 상기 제조된 PVC 수지 조성물이 공지의 카렌더링, 성형 및 압착 등의 공정을 통하여 PVC 엠보싱 방수시트로 제조되는 단계 등을 포함한다.Here, the method of manufacturing the PVC embossed waterproof sheet is more preferably surface modification in which recycled PVC powder, methyltrimethoxysilane, diphenyldiethoxysilane, and phenyltrichlorosilane are mixed in a volume ratio of 10:0.3:0.2:0.1. After adding 20 to 40 parts by weight of polyethylene, 10 to 30 parts by weight of polypropylene, 5 to 7 parts by weight of dioctyl phthalate, 3 to 5 parts by weight of carbon black, and 2 to 4 parts by weight of stearic acid to 100 parts by weight of recycled PVC powder composite. A step of manufacturing a PVC resin composition by melting at 200-250°C for 3-5 hours, and a step of manufacturing the prepared PVC resin composition into a PVC embossed waterproof sheet through known processes such as calendering, molding, and pressing. Includes etc.
재생PVC파우더는, 열에 강하고 마찰계수가 극히 낮으며 좋은 내화학성 특징을 통하여 부식을 방지하고 코팅 기능을 통하여 PVC 엠보싱 방수시트로의 제조시 방수시트의 내충격성을 향상시키는 기능을 위한 조성물로서, 적절한 점도 유지와 피막강도, 인장강도 및 내후성을 적절히 유지시키는 기능을 제공한다.Recycled PVC powder is a composition that is resistant to heat, has an extremely low friction coefficient, prevents corrosion through good chemical resistance, and improves the impact resistance of waterproof sheets when manufactured into PVC embossed waterproof sheets through a coating function. It provides the function of maintaining viscosity, film strength, tensile strength, and weather resistance appropriately.
여기서, 재생PVC파우더는, 표면개질 재생PVC파우더 복합물 제조시 10 부피비로 첨가되는데, 10 부피비를 초과하는 경우에는 구조물의 표면에 시공시 밀착 또는 접착은 강해지지만 방수시트의 중량이 증가되어 작업성이 저하되고, 10 부피비에 미만하는 경우에는 구조물의 표면으로부터 쉽게 박리되고 피막강도와 인장강도 및 내후성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 부피비를 가지는 것이 좋다.Here, recycled PVC powder is added at a volume ratio of 10 when manufacturing the surface-modified recycled PVC powder composite. If the volume ratio exceeds 10, adhesion or adhesion becomes stronger when applied to the surface of the structure, but the weight of the waterproof sheet increases, which reduces workability. If the volume ratio is less than 10, it easily peels off from the surface of the structure and the film strength, tensile strength, and weather resistance are reduced, so it is better to have a limited volume ratio as described above.
메틸트리메톡시실란은, 희석제로서 상기 혼합물들의 혼합 후 겔 상태를 유지시켜 주어 방수시트로의 제조 공정에서 제조성을 향상시키는 기능을 제공한다.Methyltrimethoxysilane, as a diluent, maintains a gel state after mixing the above mixtures and provides the function of improving manufacturability in the manufacturing process of waterproof sheets.
여기서, 메틸트리메톡시실란은, 표면개질 재생PVC파우더 복합물 제조시 0.3 부피비로 첨가되는데, 0.3 부피비를 초과하는 경우에는 점성이 너무 커지게 되어 상기 혼합물들과의 교반성이 저하되고, 0.3 부피비에 미만하는 경우에는 혼합물들의 저장 안정성이 저조하게 되어 결합성과 접착성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 부피비를 가지는 것이 좋다.Here, methyltrimethoxysilane is added at a volume ratio of 0.3 when manufacturing the surface-modified recycled PVC powder composite. If it exceeds 0.3 volume ratio, the viscosity becomes too large and the mixing ability with the mixture is reduced, and at a volume ratio of 0.3, the viscosity becomes too high. If it is less than that, there is a problem that the storage stability of the mixture is poor and the bonding and adhesiveness are reduced, so it is better to have a limited volume ratio as described above.
디페닐디에톡시실란은, 가소제로서 상기 혼합물들의 혼합 후 점도 안정성을 향상시켜 제조성이 저하되는 것을 방지하는 기능을 제공한다.Diphenyldiethoxysilane, as a plasticizer, improves viscosity stability after mixing the above mixtures and provides the function of preventing deterioration of manufacturability.
여기서, 디페닐디에톡시실란은, 표면개질 재생PVC파우더 복합물 제조시 0.2 부피비로 첨가되는데, 0.2 부피비를 초과하는 경우에는 PVC 엠보싱 방수시트의 제조시 방수시트의 물성 효과가 저하되고 끈적거림이 발생하게 되며, 0.2 부피비에 미만하는 경우에는 가소화 능력이 부족하게 되어 점도 안정성이 저하되어 제조성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Here, diphenyl diethoxysilane is added at a volume ratio of 0.2 when manufacturing the surface-modified recycled PVC powder composite. If the volume ratio exceeds 0.2, the physical properties of the waterproof sheet are reduced and stickiness occurs when manufacturing the PVC embossed waterproof sheet. If the volume ratio is less than 0.2, plasticization ability is insufficient, viscosity stability is reduced, and manufacturability is reduced, so it is better to have a limited weight portion as described above.
페닐트리클로로실란은, 상기 혼합물들을 용해하여 상호간 높은 결합력을 가지도록 하여 PVC 엠보싱 방수시트로의 가공 성형시 방수성과 내마모성을 제공하여 투수비와 흡수비를 낮추는 기능을 제공한다.Phenyltrichlorosilane dissolves the above mixtures so that they have high bonding strength to each other, providing waterproofness and abrasion resistance during processing and molding into PVC embossed waterproof sheets, thereby lowering the water permeability ratio and water absorption ratio.
여기서, 페닐트리클로로실란은, 표면개질 재생PVC파우더 복합물 제조시 0.1 부피비로 첨가되는데, 0.1 부피비를 초과하는 경우에는 상기 혼합물들의 반응속도가 너무 빨라지게 되어 교반성과 제조성이 저하되고, 0.1 부피비를 미만하는 경우에는 상기 혼합물들의 반응속도가 너무 느려지게 되어 제조 시간이 증가하게 되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Here, phenyltrichlorosilane is added at a volume ratio of 0.1 when manufacturing the surface-modified recycled PVC powder composite. If the volume ratio of 0.1 is exceeded, the reaction rate of the mixture becomes too fast, thereby reducing agitation and manufacturability, and the 0.1 volume ratio is used. If it is less than that, the reaction rate of the mixtures becomes too slow and the manufacturing time increases, so it is better to have a limited weight portion as described above.
여기서, 표면개질 재생PVC파우더 복합물은, 상기 혼합물들에 대하여 100중량부가 혼합되는데, 100중량부를 초과하는 경우에는 상기 혼합물들의 혼합시 반응속도가 너무 빨라지게 되어 교반성 및 시공성이 저하되고 100중량부에 미만하는 경우에는 상기 혼합물들의 반응속도가 너무 느려지게 되어 작업 시간이 증가하게 되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다. Here, 100 parts by weight of the surface-modified recycled PVC powder composite is mixed with the mixtures. If it exceeds 100 parts by weight, the reaction rate becomes too fast when mixing the mixtures, and the agitation and constructability are reduced, and 100 parts by weight is added. If it is less than , the reaction rate of the mixtures becomes too slow and the working time increases, so it is better to have a limited weight portion as described above.
폴리에틸렌은, PVC 수지 조성물을 통한 PVC 엠보싱 방수시트의 제조시 뛰어난 내열성, 탄성회복 및 내주름성을 제공한다.Polyethylene provides excellent heat resistance, elastic recovery, and wrinkle resistance when manufacturing PVC embossed waterproof sheets using PVC resin compositions.
여기서, 폴리에틸렌은, 표면개질 재생PVC파우더 복합물 100 중량부에 대하여 20~40 중량부가 혼합되는데, 40 중량부를 초과하는 경우에는 방수시트의 탄성도가 저하되어 외부 충격시 쉽게 파단되고, 20 중량부에 미만하는 경우에는 주름에 의한 들뜸 현상이 발생되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Here, 20 to 40 parts by weight of polyethylene is mixed with 100 parts by weight of the surface-modified recycled PVC powder composite. If it exceeds 40 parts by weight, the elasticity of the waterproof sheet decreases and is easily broken upon external impact. If it is less than that, there is a problem that the phenomenon of lifting due to wrinkles occurs, so it is better to have a limited weight portion as described above.
폴리프로필렌은, PVC 수지 조성물을 통한 PVC 엠보싱 방수시트의 제조시 높은 접착 강도와 결합도를 제공한다.Polypropylene provides high adhesive strength and bonding degree when manufacturing PVC embossed waterproof sheets using PVC resin compositions.
여기서, 폴리프로필렌은, 표면개질 재생PVC파우더 복합물 100 중량부에 대하여 10~30 중량부가 혼합되는데, 30 중량부를 초과하는 경우에는 점도가 높아지게 되어 제조성이 저하되고, 10 중량부에 미만하는 경우에는 구조물의 표면과의 접착력이 저하되어 쉽게 박리되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Here, 10 to 30 parts by weight of polypropylene is mixed with 100 parts by weight of the surface-modified recycled PVC powder composite. If it exceeds 30 parts by weight, the viscosity increases and manufacturability decreases, and if it is less than 10 parts by weight, the viscosity increases. Since there is a problem of easy peeling due to reduced adhesion to the surface of the structure, it is better to have a limited weight portion as described above.
디옥틸프탈레이트는, PVC 수지 조성물을 통한 PVC 엠보싱 방수시트의 제조시 방수시트의 연성 및 안정성을 향상시킨다.Dioctyl phthalate improves the ductility and stability of the waterproof sheet when manufacturing the PVC embossed waterproof sheet using a PVC resin composition.
여기서, 디옥틸플탈레이트는, 표면개질 재생PVC파우더 복합물 100 중량부에 대하여 5~7 중량부가 혼합되는데, 7 중량부를 초과하는 경우에는 상기 혼합물들의 연성과 안정성이 오히려 저하되어 접합 또는 압착 기능이 저하되고, 5 중량부를 미만하는 경우에는 상기 혼합물들의 교반성이 크게 저하되어 접합 기능과 두께 확보 기능이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Here, dioctyl phthalate is mixed in an amount of 5 to 7 parts by weight based on 100 parts by weight of the surface-modified recycled PVC powder composite. If it exceeds 7 parts by weight, the ductility and stability of the mixture decreases and the bonding or pressing function deteriorates. If the amount is less than 5 parts by weight, the agitation property of the mixture is greatly reduced and the bonding function and thickness securing function are deteriorated. Therefore, it is better to have the limited weight part as described above.
카본블랙은, PVC 수지 조성물을 통한 PVC 엠보싱 방수시트의 제조시 탄소원자가 서로 결합해 혼합물들의 뼈대를 제공하여 내구성, 내열성, 내화학성, 내마모성 및 내충격성 등의 물성을 제공한다.Carbon black provides physical properties such as durability, heat resistance, chemical resistance, abrasion resistance, and impact resistance by providing a framework for the mixture by combining carbon atoms when manufacturing a PVC embossed waterproof sheet using a PVC resin composition.
여기서, 카본블랙은, 표면개질 재생PVC파우더 복합물 100 중량부에 대하여 3~5 중량부가 혼합되는데, 5 중량부를 초과하는 경우에는 빠른 시간에 경화가 이루어져 PVC 엠보싱 방수시트의 성형 및 가공성이 저하되어 오히려 내마모성 및 내충격성 등이 크게 저하되고, 3 중량부를 미만하는 경우에는 구조물의 표면에 시공시 작은 충격에도 쉽게 파단되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Here, 3 to 5 parts by weight of carbon black is mixed with 100 parts by weight of the surface-modified recycled PVC powder composite. If it exceeds 5 parts by weight, it hardens quickly and the molding and processability of the PVC embossed waterproof sheet deteriorates. Wear resistance and impact resistance are greatly reduced, and if the amount is less than 3 parts by weight, there is a problem that it is easily broken even by a small impact when applied to the surface of the structure. Therefore, it is better to have a limited weight part as described above.
스테아린산은, PVC 수지 조성물을 통한 PVC 엠보싱 방수시트의 제조시 방수시트의 방수성을 향상시키는 기능을 제공한다.Stearic acid provides the function of improving the waterproofness of the waterproof sheet when manufacturing a PVC embossed waterproof sheet using a PVC resin composition.
여기서, 스테아린산은, 표면개질 재생PVC파우더 복합물 100 중량부에 대하여 2~4 중량부가 혼합되는데, 4 중량부를 초과하는 경우에는 구조물의 표면에 시공시 접착력 또는 밀착력이 저하되고, 2 중량부에 미만하는 경우에는 방수성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Here, stearic acid is mixed in an amount of 2 to 4 parts by weight per 100 parts by weight of the surface-modified recycled PVC powder composite. If it exceeds 4 parts by weight, the adhesion or adhesion to the surface of the structure decreases, and if it is less than 2 parts by weight, the adhesion or adhesion strength decreases when applied to the surface of the structure. In this case, there is a problem that waterproofness is reduced, so it is better to have a limited weight portion as described above.
한편, 본 발명에 있어서, 표면개질 재생PVC파우더 복합물에, 폴리에틸렌, 폴리프로필렌, 디옥틸프탈레이트, 카본블랙 및 스테아린산이 첨가된 후, 200~250℃에서 3~5시간 용융되도록 하는 것은, 상기 조건을 초과하는 경우에는 과팽윤이 발생되거나 고증점이 되고, 상기 조건에 미만하는 경우에는 팽윤율이 저하되는 문제점이 있으므로, 상기와 같은 온도와 시간을 통하여 교반성이 향상되도록 하는 것이 좋다.Meanwhile, in the present invention, after polyethylene, polypropylene, dioctyl phthalate, carbon black, and stearic acid are added to the surface-modified recycled PVC powder composite, it is melted at 200-250°C for 3-5 hours under the above conditions. If it exceeds the above condition, overswelling occurs or the viscosity becomes high, and if it is less than the above condition, there is a problem in that the swelling ratio decreases. Therefore, it is better to improve the stirring properties through the above temperature and time.
이하, 본 발명의 실시예에 따라 제조된 PVC 엠보싱 방수시트를 이용한 방수공법에 대해 설명하면 다음과 같다.Hereinafter, a waterproofing method using a PVC embossed waterproof sheet manufactured according to an embodiment of the present invention will be described as follows.

이후, 콘크리트 표면에 공지의 도막방수재가 도포되어 도막층이 형성되거나 접착제가 도포되어 접착층이 도포된다.Afterwards, a known coating waterproofing material is applied to the concrete surface to form a coating layer, or an adhesive is applied to form an adhesive layer.
이후, 콘크리트 표면의 도막층 또는 접착층의 경화 전에 PVC 엠보싱 방수시트가 부착 또는 접착된다.Afterwards, the PVC embossed waterproofing sheet is attached or adhered before the coating layer or adhesive layer on the concrete surface is cured.
여기서, PVC 엠보싱 방수시트는, 소정의 폭을 가지고 그 폭 보다 긴 길이를 가지면서 롤링된 구조를 가지게 되며, 콘크리트 표면에 PVC 엠보싱 방수시트의 하면이 부착 또는 접착되는 것을 통해 콘크리트 표면에 시공된다.Here, the PVC embossed waterproof sheet has a rolled structure with a predetermined width and a length longer than the width, and is constructed on the concrete surface by attaching or adhering the lower surface of the PVC embossed waterproof sheet to the concrete surface.
이때, PVC 엠보싱 방수시트가 소정의 폭을 가짐에 따라 인접한 PVC 엠보싱 방수시트가 조인트되어야 하는 경우, PVC 엠보싱 방수시트의 폭 방향 가장자리가 상호간 맞대응된 상태에서, 50mm 내지 70mm의 폭을 가지는 망사테이프가 폴리에스터 부직포의 맞대응된 부위에 부착된 후, 망사테이프를 커버하면서 우레탄실란트가 폴리에스터 부직포의 상면에 100mm의 폭으로 도포 및 시공되어 보강층이 구성될 수 있다.At this time, when the PVC embossed waterproof sheet has a predetermined width and adjacent PVC embossed waterproof sheets must be jointed, a mesh tape having a width of 50 mm to 70 mm is used with the width direction edges of the PVC embossed waterproof sheet facing each other. After being attached to the facing portion of the polyester nonwoven fabric, urethane sealant can be applied and installed to a width of 100 mm on the upper surface of the polyester nonwoven fabric while covering the mesh tape to form a reinforcing layer.

Meanwhile, in the present invention, it is preferable that the space between the concrete surface and the PVC embossed waterproof sheet is communicated with the outside through a separate air vent per 200 m 2 so that moisture on the concrete surface is discharged to the outside through the air vent.
