Description
본 발명은 건축물의 옥상이나 지하 주차장 상부슬라브, 지하외벽, 지하 기초바닥부위와, 지하철ㆍ지하차도ㆍ공동구(전력구ㆍ통신구)등의 지하 콘크리트 구조물의 외부방수를 위하여 아스팔트 펠트시트와 함께 이중방수를 이루기 위한 겔(Gel)상의 고무아스팔트 도막방수재 조성물 및 그의 제조방법에 관한 것으로, 더욱 상세하게는 콘크리트 바탕면과의 강한 접착력을 나타내면서 완전 경화되지 않는 겔(Gel)상의 점성을 유지하여 신뢰적인 1차 방수를 수행하고, 2차방수를 위한 시트와 완전한 결합으로 도막 및 시트 이중 방수를 행하여 복합방수 효과를 극대화할 수 있는 겔상태의 고무아스팔트 도막방수재 조성물 및 그의 제조방법에 관한 것이다. The present invention is a double roof with asphalt felt sheet for the external waterproofing of the roof top of the building or the upper slab of the underground parking lot, the basement outer wall, the basement floor of the underground, and the underground concrete structures such as subways, underground roads and public areas (power and communication areas). The present invention relates to a rubber asphalt coating waterproofing composition on a gel to achieve waterproofing, and to a method of manufacturing the same. More particularly, the present invention relates to a rubber asphalt coating waterproofing composition and a method of manufacturing the same. The present invention relates to a gel-like rubber asphalt coating waterproofing composition and a method for producing the same, which can perform the first waterproofing and maximize the composite waterproofing effect by performing double coating of the coating film and the sheet in perfect combination with the sheet for secondary waterproofing.
일반적으로, 건축구조물의 옥상이나 지하기초바닥 및 지하외벽, 지하주차장 상부슬라브 방수와 토목구조물로서 지하철ㆍ지하차도ㆍ전력구ㆍ통신구 등의 공동구 와 같은 지하 콘크리트 구조물의 방수에 적용되는 방수공법은 ① 아스팔트 3겹8층 방수, ② 아스팔트 시트방수, ③ 우레탄계 또는 고무아스팔트계 도막방수, ④ 벤토나이트 방수 등으로 분류할 수 있다. 국내에 적용되고 있는 보편적인 방수공법으로는 1910년-1970년대까지 아스팔트 3겹8층 방수가 주종을 이루었으며, 1980년대 이후로는 시공의 간편성과 경제성의 이유로 아스팔트 시트방수로 변경하여 적용되었고, 우레탄계 또는 고무아스팔트계 도막방수, 벤토나이트방수 등이 병합되어 적용되고 있었다.In general, the waterproofing method applied to the waterproofing of underground concrete structures such as subways, underground roads, power stations, and communication areas as waterproofing roofs, underground basement and underground outer walls, upper slabs of underground parking lots, and civil engineering structures. It can be classified into ① waterproofing of 3 layers and 8 layers of asphalt, ② waterproofing of asphalt sheets, ③ waterproofing of urethane or rubber asphalt based coatings, and ④ waterproofing of bentonite. As a general waterproofing method applied in Korea, asphalt 3-layer 8-layer waterproofing was predominant until 1910-1970s, and after 1980s, it was changed to asphalt sheet waterproofing for reasons of ease of construction and economic feasibility. Alternatively, rubber asphalt coating film waterproofing and bentonite waterproofing have been applied in combination.
상기 아스팔트 3겹8층 방수는 1910년대에 일본으로부터 아스팔트를 도입하여 국내에서 처음 적용되기 시작하였으며, 8층의 적층방수에 의한 방수층의 두께가 두꺼워 방수효과가 우수하며, 방수 안정성이 높아 70여년 이상의 오랜기간동안 적용실적을 나타내었다. 그러나, 상기의 아스팔트 3겹8층 공법은 고체의 블로운 아스팔트(Blown Asphalt)를 공사현장에서 고온(220℃-250℃)으로 가열해야 하고, 또 가열 용융시에 발생되는 냄새ㆍ연기로 인한 환경공해문제가 발생하고 있으며, 작업시 작업인부들의 화상 사고 발생 위험성과 복잡한 작업공정으로서 방수기능공의 특별한 기술 숙련도가 요구되며 시공 인건비가 많이 소요되는 단점이 있다.The asphalt three-layer 8-layer waterproofing was first applied in Korea by introducing asphalt from Japan in the 1910s, and the waterproof layer is thick due to the waterproofing of 8 layers of layers. The application results are shown for a long time. However, the above-mentioned three-ply eight-layer asphalt method requires heating solid blown asphalt (Blown Asphalt) at a high temperature (220 ° C-250 ° C) at the construction site, and the environment caused by the smell and smoke generated during heat melting. Pollution problems are occurring, the risk of burn accidents of workers and the complicated work process requires a special technical skill of waterproof workers and a lot of construction labor costs.
이와 같은 환경공해가 발생하는 문제점으로 인해 1980년대 이후부터는 국내 건설공사 현장에서 아스팔트 3겹8층 방수의 적용이 점차 어려워지기 시작하였다. As a result of such environmental pollution, it has become increasingly difficult to apply waterproofing of 3 layers and 8 layers of asphalt at domestic construction sites since the 1980s.
이에 대한 대안으로서 1970년대 후반에 아스팔트 시트 방수재가 외국으로부터 수입되어 처음 적용되기 시작하였으며, 1980년대 초 아스팔트 시트 방수재가 국내에서 생산 보급됨으로써 종래의 아스팔트 3겹8층 방수에 비교하여 시공의 간편성 과 경제성으로 인해 급속도로 널리 보급 적용되기 시작하였다.As an alternative to this, asphalt sheet waterproofing material was imported from foreign countries in the late 1970s and applied for the first time.In the early 1980s, asphalt sheet waterproofing material was produced and distributed in Korea. Due to this, it began to be widely applied.
아스팔트 시트방수의 문제점으로는 아스팔트 시트 방수층이 콘크리트 바탕면과의 접착력 부족에 의한 방수층의 들뜸현상 발생과, 방수시트 연결이음부위에 토우치(Torch)를 사용하여 가열 용융접합시 아스팔트 콤파운드의 연소, 산화에 의한 방수시트 연결이음부위 수밀성이 약화되어 이음부에서의 누수사고가 빈번하게 발생되는 문제점이 있었다. 또한 상기 공법은 방수하자 발생시 결함 부위 발견이 어렵고 보수비용이 많이 소요되는 커다란 단점을 나타내면서 1990년대 이후로는 국내 건설업체들이 아스팔트 시트 방수의 적용을 기피하는 현상이 발생되었다.As for the problems of waterproofing asphalt sheet, the asphalt sheet waterproofing layer is lifted due to the lack of adhesion to the concrete base surface and the asphalt compound is burned when heated and melt-bonded by using a torch at the joint of the waterproof sheet. The watertightness of the joint portion of the waterproof sheet connection by the oxidation is weakened, which causes a problem of frequent leakage at the joint. In addition, the method shows a great disadvantage that it is difficult to find a defect site and take a lot of repair costs when the water-resistant defects occur, and since the 1990s, domestic construction companies have avoided the application of waterproofing asphalt sheet.
우레탄계 도막방수와 고무아스팔트계 도막방수는 1980년대 후반이후부터 로울러나 붓을 사용하는 간편한 도포시공 방법으로서, 시공성 및 방수층의 신장력이 우수하여 콘크리트 구조체의 미세균열에도 대응할 수 있는 장점이 있으나, 도막방수재를 수차례 도포해야 하기 때문에 도막 방수층의 균등한 두께를 형성하는데 어려움이 있고, 방수층의 부분적인 기포발생에 의해 방수층 결함부위가 빈번하게 발생되는 단점이 있다.Urethane-based waterproofing and rubber asphalt-based waterproofing are simple application methods using rollers or brushes since the late 1980s, but they have the advantage of being able to cope with micro-cracking of concrete structures due to their excellent workability and extension of waterproof layer. It is difficult to form an even thickness of the coating film waterproof layer because it needs to be applied several times, and there is a disadvantage that the defects of the waterproof layer are frequently generated by partial bubble generation of the waterproof layer.
벤토나이트 방수의 경우 원자재 소디움 벤토나이트(Sodium Bentonite)의 독특한 수화팽창 특성에 의해 물과 반응시 원래의 체적보다 13배 ∼ 16배 팽창하여 물을 흡수하는 성질이 있어 수압이 높은 지하 콘크리트 구조물 방수에 이상적인 방수효과를 나타내지만, 원자재 소디움 벤토나이트가 전량 외국으로부터 수입되기 때문에 자재비가 다소 고가이며, 벤토나이트 방수시공 후 하자 발생시 결함부위 발견이 어려워 근원적인 하자 보수가 어렵다는 단점이 있다.Bentonite waterproofing is absorbed by 13 ~ 16 times the original volume when reacting with water due to the unique hydration expansion characteristic of raw material sodium bentonite, which is ideal for waterproofing underground concrete structures with high water pressure. Although it is effective, the total cost of raw material sodium bentonite is imported from foreign countries, the material cost is rather expensive, and it is difficult to find the defects when defects occur after bentonite waterproofing.
상기에서와 같이 종래에 적용되고 있는 방수공법별로 나름대로의 장ㆍ단점을 가지고 있으나 방수공사 시공이 작업인부들의 인력에 의한 시공으로서 시공부주의에 의한 방수하자 발생이 빈번하다는 문제점을 공통적으로 내포하고 있다. 이와 같은 시공 부주의에 의한 방수하자 발생을 최소화하기 위하여 2000년 이후부터는 방수 공사비가 다소 많이 소요되더라도 시트방수나 도막방수의 단층 방수 시공방법을 보완하여 시트+시트 또는 도막+시트 등의 시공방법에 의한 이중방수(복합방수) 시공의 필요성을 느끼게 되어 이중방수 또는 복합방수공법들이 개발되어 적용사례가 점진적으로 늘어나고 있는 추세이다.As described above, each waterproof method has its own advantages and disadvantages, but it has a common problem that waterproof construction is frequently caused by carelessness of construction workers due to the workforce's manpower. To minimize the occurrence of waterproof defects due to such careless construction, even after 2000, even though the waterproof construction cost is somewhat high, the single-layer waterproof construction method for sheet waterproofing or waterproofing of the film is supplemented, Due to the necessity of double waterproof (composite waterproof) construction, double or multiple waterproof methods have been developed, and the application cases are gradually increasing.
본원 출원인은 특허등록 제0278173호에서 제시된 콘크리트 구조물의 도막 및 시트 이중방수재 및 특허등록 제0533231호에서 제시된 도막방수층 보강을 위한 스트레치 고무아스팔트펠트 및 그를 이용한 도막 및 펠트 적층방수재의 특허권자로서 일찍이 상기한 종래의 기술을 개선 보완하여 실용화함으로써 국내외 건설시장에 널리 보급하고 있다.The applicant of the present application is the patentee of the coating and sheet double waterproofing material of the concrete structure presented in Patent Registration No. 0278173 and the stretch rubber asphalt felt for reinforcing the coating waterproof layer provided in Patent Registration No. 0533231 and the coating film and felt laminated waterproofing material using the same. It is widely used in domestic and overseas construction markets by improving and complementing its technology.
그러나, 본원출원인에 의해 제안된 도막방수재는 초기 겔(gel)상태를 유지하기 위하여 아스팔트 화합물의 조제시 석유용제를 혼합하고 있다. 그러나, 상기한 도막방수재는 용제가 휘발되고 난 후에 경화상태로 변하기 때문에 유연성이 다소 저하되는 문제점이 있다. However, the coating film waterproofing material proposed by the present applicant is mixing the petroleum solvent when preparing the asphalt compound to maintain the initial gel (gel) state.
