Description
본 고안은 발포층을 포함하는 폴리염화비닐(PVC) 방수시트에 관한 것으로, 더욱 상세하게는 일반 PVC시트에 발포층을 더 적층시켜 PVC시트의 신축·팽창에 대한 저항성을 향상시킴은 물론 단열성 및 내충격성을 향상시킨 발포층을 포함하는 폴리염화비닐 방수시트에 관한 것이다.The present invention relates to a polyvinyl chloride (PVC) waterproof sheet including a foam layer, and more specifically, by further laminating a foam layer on a general PVC sheet to improve resistance to expansion and expansion of the PVC sheet, as well as thermal insulation and The present invention relates to a polyvinyl chloride waterproof sheet including a foam layer having improved impact resistance.
일반적으로 빌딩 구조물의 옥상이나 주차장의 상부 등에는 누수를 방지하기 위해 방수 공사를 하게 되는데, 시공상 편의로 일정 규격의 방수시트를 바탕면에 펼쳐 설치하여 방수층을 형성시키는 시트방수가 널리 채택되고 있다.In general, waterproof construction is performed on the roof of a building structure or the upper part of a parking lot to prevent leakage. Sheet waterproofing is widely adopted to form a waterproof layer by spreading a predetermined size waterproof sheet on a ground surface for convenience of construction. .
합성고분자계 방수용 시트는 신장률이 크기 때문에 건축물 모체의 균열 또는 거동에 대한 추종성 및 순응성이 양호하고 내후성 내열성 등 충분한 내구성을 가지고 있어 통상 시트방수에 채택되어 사용되고 있다. 그러나, 큰 신장률 때문에 외기의 온도변화에 민감하게 대응하여 수축·팽창이 잘 일어났으며, 이는 방수시트의 방수성능을 저하시키는 원인으로 작용하였다. 즉, 방수시트의 수축·팽창정도가 크고 수축·팽창이 지속적으로 반복되면 방수시트는 부착 설치된 바탕면에서부터 용이하게 떨어지고 부착성능을 상실하게 되며 나아가 균열에 의한 파손이 생기기 쉬웠다.Synthetic polymer waterproof sheet has a high elongation rate, so it has good durability and conformity to cracking or behavior of building matrix, and has sufficient durability such as weather resistance and heat resistance, so it is usually used for sheet waterproofing. However, due to the large elongation, shrinkage and expansion occurred well in response to the temperature change of the outside air, which acted as a cause of lowering the waterproof performance of the waterproof sheet. In other words, if the shrinkage and expansion degree of the waterproof sheet is large and the shrinkage and expansion is repeated continuously, the waterproof sheet easily falls from the installed base surface, loses the adhesion performance, and is more likely to be damaged by cracks.
본 고안은 상기와 같은 문제점을 해결하고자 안출된 것으로서, 일반 PVC시트에 발포층을 더 적층시켜 PVC시트의 신축·팽창에 대한 저항성을 향상시킴은 물론 단열성 및 내충격성을 향상시킨 발포층을 포함하는 폴리염화비닐 방수시트를 제공하는데 그 목적이 있다.The present invention was devised to solve the above problems, and by further laminating a foam layer on a general PVC sheet to improve the resistance to expansion and expansion of the PVC sheet, as well as to include a foam layer having improved insulation and impact resistance The object is to provide a polyvinyl chloride waterproof sheet.

본 고안의 발포층을 포함하는 폴리염화비닐 방수시트는 폴리염화비닐(PVC) 시트; 상기 폴리염화비닐 시트 표면 위에 발포되어 형성되는 폴리염화비닐 발포층; 및, 상기 폴리염화비닐 발포층 표면 위에 위치하여 폴리염화비닐 발포층을 소정 두께로 성형시키는 부직포;를 포함하여 구성된다.Polyvinyl chloride waterproof sheet comprising a foam layer of the present invention is a polyvinyl chloride (PVC) sheet; A polyvinyl chloride foam layer formed by foaming on a surface of the polyvinyl chloride sheet; And a nonwoven fabric positioned on a surface of the polyvinyl chloride foam layer to mold the polyvinyl chloride foam layer to a predetermined thickness.
이하, 도면에 따라 본 고안을 설명한다.Hereinafter, the present invention will be described with reference to the drawings.
도 2는 본 고안의 발포층을 포함하는 폴리염화비닐 방수시트의 사시도(a) 및 단면도(b)로, 본 고안의 발포층을 포함하는 폴리염화비닐 방수시트(10)는 폴리염화비닐 시트(11), 폴리염화비닐 발포층(12) 및 부직포(13)를 포함하여 구성된다.2 is a perspective view (a) and a cross-sectional view (b) of a polyvinyl chloride waterproof sheet including a foam layer of the present invention, polyvinyl chloride waterproof sheet 10 including a foam layer of the present invention is a polyvinyl chloride sheet ( 11), the polyvinyl chloride foam layer 12 and the nonwoven fabric 13 are comprised.
폴리염화비닐 시트(11)는 1차적인 방수층을 형성하는 부분으로 방수하고자 하는 바탕면(100)에 접하여 부착 설치되거나 바탕면위에 프라이머(50)가 도포되는 경우에는 프라이머 위에 부착 설치된다. 통상적으로 시트방수에서는 합성고무계, 합성수지계 재료를 사용하는데, 본 고안에서는 합성수지계 재료 중 적용성 및 경제성에서 유리한 폴리염화비닐을 채택하고 있으며 폐자원을 재활용한 폴리염화비닐 시트 또한 채택가능하다. 합성수지계 재료 중 폴리염화비닐(PVC)은 폴리에틸렌(PE)보다 안착성이 우수하고 난연재로서 자기소화성이 있기 때문에 방수용 시트의 재료로서 더 적합하다.The polyvinyl chloride sheet 11 is attached to contact the base surface 100 to be waterproofed as a part forming the primary waterproof layer, or when the primer 50 is applied on the base surface, is attached to the primer. Generally, synthetic rubber and synthetic resin materials are used in sheet waterproofing. In the present invention, polyvinyl chloride sheets, which are advantageous in applicability and economic efficiency, are adopted among synthetic resin materials. Among the synthetic resin materials, polyvinyl chloride (PVC) is more suitable as a material for a waterproof sheet because it has better seating properties than polyethylene (PE) and has self-extinguishing property as a flame retardant.
폴리염화비닐 발포층(12)은 상기 폴리염화비닐 시트(11) 표면 위에 발포되어 형성되는 것으로, 일정하게 성형되면 상기 발포층(12)은 접착력이 우수하여 상기 폴리염화비닐 시트(11)와 일체화된 적층구조로 형성되며 시트부분과 PVC이라는 동일한 재료를 사용함으로써 이질적인 재료들을 적층시키는 경우보다 우수한 방수성능을 발현하게 된다. 또한 상기 폴리염화비닐 발포층(12)은 폴리염화비닐 시트(11)에 비해 신축, 팽창에 대한 저항성이 크기 때문에 폴리염화비닐 시트(11)가 변형을 일으키는 경우에는 변형을 잡아주는 역할을 하여 본 고안의 폴리염화비닐 방수시트(10)의 치수안정성을 확보할 수 있도록 한다.The polyvinyl chloride foam layer 12 is formed by foaming on the surface of the polyvinyl chloride sheet 11, and when molded uniformly, the foam layer 12 is excellent in adhesive strength and integrated with the polyvinyl chloride sheet 11 It is formed in a laminated structure, and by using the same material as the sheet portion and PVC, it exhibits excellent waterproofing performance than when stacking heterogeneous materials. In addition, since the polyvinyl chloride foam layer 12 has a greater resistance to stretching and expansion than the polyvinyl chloride sheet 11, the polyvinyl chloride sheet 11 serves to hold the deformation when the polyvinyl chloride sheet 11 causes deformation. It is to ensure the dimensional stability of the polyvinyl chloride waterproof sheet (10) of the invention.
동일 두께의 방수시트라도 일부 두께를 상기와 같은 발포층(12)으로 형성시키면 전체가 통상적인 시트로 형성된 것보다 가벼워 운반, 취급 및 시공이 상당히 용이하게 되고, 또한 발포층(12)의 쿠션성능으로 내충격성이 우수할 뿐 아니라 소음방지 및 단열성에서 우수한 효과를 발휘하게 된다.Even if the waterproof sheet having the same thickness is formed with the foam layer 12 as described above, the overall thickness is lighter than that of the conventional sheet, so that transportation, handling, and construction are considerably easier, and the cushioning performance of the foam layer 12 is also excellent. As well as excellent impact resistance, it exhibits excellent effects in noise prevention and insulation.
부직포(13)는 상기 폴리염화비닐 발포층(12) 표면 위에 위치하여 폴리염화비닐 발포층(12)을 소정 두께로 성형시켜 그 형태를 유지하는 역할을 한다. 또한 본 고안의 발포층을 포함한 폴리염화비닐 방수시트(10)가 바탕면에 부착 설치되면 방수시트를 보호마감하기 위한 우레탄도막방수 등을 하여 도막방수층(40)을 형성하게 되는데, 상기 부직포(13)는 이러한 도막방수층(40)에 함침되어 방수시트(10)와 도막방수층(40)을 일체화하여 방수성 및 수밀성을 강화시킨다.The nonwoven fabric 13 is positioned on the polyvinyl chloride foam layer 12 surface and serves to maintain the shape by molding the polyvinyl chloride foam layer 12 to a predetermined thickness. In addition, when the polyvinyl chloride waterproof sheet 10 including the foam layer of the present invention is attached to the base surface, the waterproofing layer 40 is formed by waterproofing urethane coating for protecting the waterproof sheet, and the nonwoven fabric 13 ) Is impregnated in the coating layer waterproof layer 40 to integrate the waterproof sheet 10 and the coating layer waterproof layer 40 to enhance the waterproof and water-tightness.
본 고안의 발포층을 포함하는 폴리염화비닐 방수시트에 따르면, 외기의 온도변화에 따라 신축·팽창이 용이한 일반 PVC시트에 발포층을 더 적층시킴으로써 PVC시트의 신축·팽창에 대한 저항성을 향상시킬 수 있음은 물론 발포층으로 인해 단열성 및 내충격성을 향상을 기대할 수 있게 된다.According to the polyvinyl chloride waterproof sheet including the foam layer of the present invention, by further laminating the foam layer on a general PVC sheet that is easy to stretch and expand according to the temperature change of the outside air to improve the resistance to expansion and expansion of the PVC sheet Of course, due to the foam layer can be expected to improve the heat insulation and impact resistance.
