Description

폴리비닐클로라이드 방수시트 및 그 제조 방법{Polyvinil Chlorid Water Proof Sheet and Method for Producting Thereof}Polyvinyl Chloride Water Proof Sheet and Method for Producting Thereof}

본 발명은 폴리비닐클로라이드 방수시트 및 그 제조 방법에 관한 것으로서, 보다 상세하게는 방수 시공시 도막방수재와의 부착강도를 향상시키기 위하여 폴리아크릴에시드계 수지를 코팅한 폴리비닐클로라이드(PVC) 방수시트 및 그 제조방법에 관한 것이다. The present invention relates to a polyvinyl chloride waterproof sheet and a method of manufacturing the same, and more particularly, to a polyvinyl chloride (PVC) waterproof sheet coated with a polyacrylic acid-based resin in order to improve the adhesion strength with the coating waterproofing material during waterproof construction and It relates to a manufacturing method.

일반적으로 건축물을 형성하는 콘크리트나 몰탈과 같은 무기질 재료의 하지에는 균열로 인한 누수 및 결로 현상이 발생하며, 이 같은 누수 및 결로로 인해 건물의 내구성을 약화시키거나 노후화를 촉진시키는 결과를 초래하고 있다. In general, the ground of inorganic materials such as concrete or mortar forming a building causes leakage and condensation due to cracks. Such leakage and condensation may result in weakening the durability of the building or promoting aging. .

따라서 이러한 하자 발생의 원인을 제거하기 위하여 건물의 옥상, 외벽 등의 외부에는 방수시공을 하고 있으며, 이 같은 방수시공에는 방수시트를 사용한 시트방수공법, 도막 방수재료를 사용한 도막 방수공법 및 시트와 도막을 함께 사용한 복합 도막 방수공법이 사용되고 있다. Therefore, in order to eliminate the cause of such defects, waterproofing is performed on the outside of the roof, outer wall, etc. of the building, and the waterproofing method is a sheet waterproofing method using a waterproof sheet, a coating film waterproofing method using a coating film waterproofing material, and a sheet and a coating film. The composite coating waterproofing method using together is used.

종래의 방수공법에 의하면, 합성 고분자계 시트 방수공법은 합성 고분자계 시트를 사용하므로 시공이 용이한 장점은 있으나, 그 시트가 박막이기 때문에 쉽게 손상될 수 있으며, 수밀성의 약한 문제점이 있다. 또한, 이 같은 고분자계 시트를 사용하는 방수공법은 토목용의 시트를 병용해야 하고 보호층을 고려해야하는 문제점이 있다. According to the conventional waterproofing method, the synthetic polymer sheet waterproofing method has an advantage of easy construction because it uses a synthetic polymer sheet, it can be easily damaged because the sheet is a thin film, there is a weak problem of water tightness. In addition, the waterproof method using such a polymer-based sheet has a problem in that a civil engineering sheet should be used in combination and a protective layer should be considered.

또한, 개량 아스팔트 시트 방수공법은 토오치 버너로 개량 아스팔트 시트를 점착시키는 공법으로 수밀성을 확보할 수 있어 지하방수용으로 적용된다. 이 같은 개량 아스팔트 시트 방수공법은 현재 가장 일반적으로 사용되는 공법으로서 방수시트의 뒷면에 부착된 아스팔트를 프로판 가스버너(토치버너)로 가열하여 용융시킨 후 시트를 콘크리트 슬라브(slab)에 펼쳐 점착시키는 방법이다. 이 같은 개량 아스팔트 시트는 보강용 부직포 시트가 아스팔트 시트와 동일한 크기로 일측면에 열융착되어 있고, 아스팔트 시트의 타측면에는 롤형으로 제작시에 서로 접착되는 것을 방지하기 위한 이형지가 부착되어 있다. In addition, the improved asphalt sheet waterproofing method is a method of adhering the improved asphalt sheet to the torch burner to secure watertightness and is applied for underground waterproofing. This improved asphalt sheet waterproofing method is currently the most commonly used method of heating the asphalt attached to the back of the waterproof sheet with a propane gas burner (torch burner) to melt and then spread the sheet on the concrete slab (slab) to be. Such an improved asphalt sheet has a non-woven reinforcing sheet is heat-sealed on one side with the same size as the asphalt sheet, and the other side of the asphalt sheet is attached with a release paper for preventing the sheet from being adhered to each other during roll production.

그러나 이 같은 개량 아스팔트 시트 방수공법은 각 아스팔트 시트의 콘크리트 슬라브에 대한 전면부착과 아스팔트 시트 사이의 조인트 부분 처리 후 보강재 작업을 거쳐야 하기 때문에 시트 설치의 작업성이 저하되고 조인트 부분의 수밀성 확보가 곤란한 문제점이 있다.However, this improved asphalt sheet waterproofing method is required to go through the reinforcement work after the front attachment to the concrete slab of each asphalt sheet and the joint portion treatment between the asphalt sheets, so that the workability of the seat installation is reduced and it is difficult to secure the watertightness of the joint portion. There is this.

한편, 한국 특허공개 제1999-31067호에는 조인트 부분의 수밀성을 강화하기 위하여 아스팔트 시트와 폴리우레탄 도막 방수재의 장점들을 택하고 단점들을 서로 보완하도록 아스팔트 시트 구조를 개량하여 접착력을 증대시켜 주는 복합 방수구조 및 그 시공방법이 개시되어 있다. On the other hand, Korean Patent Publication No. 1999-31067 discloses a composite waterproof structure that takes advantage of the asphalt sheet and the polyurethane coating waterproof material to enhance the watertightness of the joint portion and improves the adhesive strength by improving the asphalt sheet structure to compensate for the disadvantages. And a construction method thereof.

이 같은 복합 방수구조는 이음부의 끝단부들이 상호 소정의 간격을 유지하면서 슬라브층 상면에 부설되도록 하되, 아스팔트로 형성되는 아스팔트 시트의 상면에 부직포 하부의 일부가 융착되어 일체를 이루며, 그 상부의 일부는 외부로 돌출되게 만들어지는 바탕 방수시트와, 상기 바탕 방수시트의 상면에 액상의 폴리우레탄을 도포하여 형성되는 폴리우레탄층으로 구성되어 있다.Such a composite waterproof structure is to be placed on the upper surface of the slab layer while maintaining the predetermined distance between the ends of the joint, but a part of the lower portion of the nonwoven fabric is fused to the upper surface of the asphalt sheet formed of asphalt to form an integral part of the upper portion The base is made of a base waterproof sheet made to protrude to the outside, and a polyurethane layer formed by applying a liquid polyurethane on the upper surface of the base waterproof sheet.

이 같은 복합 방수구조의 방수공법은 공정회수가 적어 시공이 간단하고 방수층의 두께가 일정하며 신율 및 균열 저항성이 있어 거동이 있는 바탕에 사용이 가능하고 노출공법이 가능한 장점이 있다. The waterproof method of such a composite waterproof structure has the advantage that the construction is simple, the thickness of the waterproof layer is constant, the thickness of the waterproof layer is constant, and the elongation and crack resistance can be used on the ground with the behavior and the exposure method is possible.

그러나, 이음부와 단부에서 누수가 많이 발생되고, 이 같은 누수의 원인을 찾아내기 곤란하며, 구체와 절연되어 부풀음 및 파단이 잘 일어나고 통기성이 없어 별도의 탈기장치가 필요하고, 유기재료로서 경년에 따른 열화가 잘 일어나는 문제점이 있다. However, many leaks occur at the joints and ends, and it is difficult to find the cause of such leaks, and it is insulated from the sphere, causing swelling and rupture well, and there is no breathability, so a separate degassing device is needed. There is a problem that deterioration occurs well.

또한, 우레탄 방수공법은 신축성이 양호하며 1mm 미만의 바탕균열에도 견딜 수 있고, 바탕면과 접착성이 우수한 일반적으로 사용하는 도막 방수공법이다. In addition, the urethane waterproofing method is good elasticity and can withstand the cracks of less than 1mm, and is a commonly used coating waterproofing method excellent in adhesion to the base surface.

그러나, 이 같은 우레탄 방수공법은 바탕의 습기가 8% 이상의 경우 접착시 불량이 발생할 수 있고, 부풀음 현상이 발생하며 경화시간이 길다는 문제점과 수직부위의 흐름성이 크다는 문제점이 있다.However, such a urethane waterproofing method may cause a defect in adhesion when the base moisture is more than 8%, swelling phenomenon occurs, there is a problem that the curing time is long and the flowability of the vertical portion is large.

본 발명은 상기와 같은 문제점들을 해결하기 위해 발명된 것으로서, 본 발명의 목적은 폴리우레탄 도막 방수재와의 복합 방수 시공시 도막 방수재와의 부착강도를 향상시킨 폴리비닐클로라이드 방수시트를 제공하는데 있다.

이하 본 발명에 따른 폴리비닐클로라이드 방수시트 및 그 제조 방법을 바람직한 실시예를 참조로하여 상세히 설명한다. Hereinafter, a polyvinyl chloride waterproof sheet and a method of manufacturing the same according to the present invention will be described in detail with reference to a preferred embodiment.

본 발명에 따른 폴리비닐클로라이드 방수시트는 역상현탁중합 방법을 이용하여 획득한 입자 형태의 폴리아크릴에시드계 수지를 아크릴에시드 50~80중량부와 에틸아크릴레이트 50~70중량부를 혼합 한후 50~60℃에서 수산화 나트륨 3~4중량부를 첨가하여 pH(수소이온 농도)가 7~8상태가 되도록 중화시킨 후 포타슘퍼설페이트 0.2~0.4중량부 및 증류수 80~90중량부 를 첨가하여 분산상을 제조하였다.  The polyvinyl chloride waterproof sheet according to the present invention is 50 to 60 ℃ after mixing 50 to 80 parts by weight of acrylic acid and 50 to 70 parts by weight of ethyl acrylate resin in the form of particles obtained by using the reverse phase suspension polymerization method 3 to 4 parts by weight of sodium hydroxide was added to neutralize the pH (hydrogen ion concentration) to a state of 7 to 8, and then 0.2 to 0.4 parts by weight of potassium persulfate and 80 to 90 parts by weight of distilled water were added to prepare a dispersed phase.
