Description

수용성 아크릴 폴리머를 이용한 방수시트 및 그 제조방법{Method for waterproof sheets of acryl polymer}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a waterproof sheet using water-soluble acrylic polymer,

본 발명은 수용성 아크릴 폴리머를 이용한 방수시트 및 그 제조방법에 관한 것으로, 좀더 상세하게는 내구성이 뛰어난 글래스화이버메쉬포와 합성섬유부직포를 순차적으로 마련하고 상부로 둑부를 형성하여 수용성아크릴폴리머방수제의 방수층과 이산화규소액의 규산층을 마련한 후 압착 및 건조시킨 후 무황변아크릴우레탄의 상부코팅층을 형성하는 방수시트를 제공하여 글래스화이버메쉬포에 의해 내구성을 향상시켜 장기간 사용에도 노후되는 것을 방지하여 방수기능을 장기간 지속할 수 있도록 하는 것에 관한 것이다.
The present invention relates to a waterproof sheet using a water-soluble acrylic polymer and a method for producing the same. More specifically, the present invention relates to a waterproof sheet using a water-soluble acrylic polymer, A waterproof sheet for forming a top coating layer of non-yellowing acrylic urethane after providing a siliceous layer of siliceous liquid of silicon dioxide, followed by compression and drying, is provided to improve durability by a glass fiber mesh cloth to prevent aging due to long- To be able to last for a long time.

일반적으로 방수는 인류가 주거생활을 하면서부터 빗물 등으로부터 쾌적하고 편안한 생활을 하기 위하여 오랜 옛날부터 시행하여 왔으며, 과거에는 비나 누수가 발생하면 임시방편으로 역청 물질인 아스팔트 등을 도포하여 왔으나, 시대에 흐름에 따라 토목 및 건축 분야에서의 방수시스템의 중요성이 평가되면서 과거부터 현재까지 각종의 도막방수재 또는 시트 방수재가 개발되고 사용되어 왔으며, 종래의 각종의 방수재에 따른 장점과 단점이 있고, 방수재의 단점으로 인한 누수발생 또는 사용상의 불편으로 단점보다는 장점이 더욱 많은 우수한 방수재의 출현을 절실히 요구하고 있는 것이다.
In general, waterproofing has been practiced from a long time ago in order to live a pleasant and comfortable life from rainwater and so on while mankind has been living in a residence. In the past, when rain or water leaked, asphalt, which is a bitumen material, was applied as a temporary measure. As the importance of the waterproof system in the civil engineering and construction fields has been evaluated according to the flow, various kinds of coating film waterproofing material or sheet waterproofing material have been developed and used from the past to the present. There are advantages and disadvantages according to the conventional various waterproofing materials, It is urgently required to have a waterproof material which is more advantageous than a disadvantage due to leakage or inconvenience in use.

그리고, 방수시트의 시공방법으로는 건축구조물의 바탕면에 누수를 방지하기 위해 사용되는 방수시트의 시공으로는, 크게 하도, 중도, 상도의 세가지 공정으로 나뉘게 되며, 먼저 하도공정은 콘크리트표면의 바탕면 처리후 접착용 프라이머를 도포하는 것이며, 중도공정은 1,2차로 나누어 그 상면에 도막방수제를 바르는 작업이며, 상도공정은 그 위로 코팅제를 발라 마감하는 것을 말한다.
As a waterproofing sheet construction method, the waterproof sheet used to prevent water leakage on the base surface of a building structure is divided into three processes of largely, middle, and top. And the primer is applied after the surface treatment. In the intermediate process, the coating agent is applied to the top surface of the substrate in the first and second order, and the top coat process is a method of coating the coating agent thereon.

그러나, 이러한 하도, 중도, 상도를 거치는 방수시트의 시공은 겹층시공이기 때문에 방수효과가 우수함과 동시에 내구성 및 수밀성이 뛰어나며 방수에 신뢰성이 높은 장점이 있는 반면에, 각각의 공정을 건조시켜 겹층해야 하므로 작업이 번거러울뿐 아니라 시공시 건조시켜야 함으로 시공을 연속적으로 하기가 어려워 공사기간을 늘려야 하는 문제점이 있으며, 또 전체적으로 현장시공으로 이루어 지므로 높은 평면의 품질을 얻기에는 특별한 시공기술이 요구되어 인건비가 많이 들뿐만 아니라, 중도공정의 도막방수제를 형성하기 위해서 원재료를 배합하여야 하는 번거러움과 숙련도를 요구하여 불편하였다.
However, since the construction of the waterproof sheet passing through the lower, middle, and upper surfaces is advantageous in waterproof effect, durability and watertightness because it is a double layer construction, and it is advantageous in waterproof and reliability, Since it is difficult to work and it must be dried during construction, there is a problem that it is difficult to carry out the construction continuously. Therefore, there is a problem that the construction period is increased. Also, since the construction is performed on the whole, a special construction technique is required to obtain high flat quality. But also the inconvenience and skill that it is necessary to formulate the raw material to form the waterproofing agent of the coating film of the intermediate process.

또한, 방수재는 초기에 액상의 아스팔트 방수재를 주로 사용하였고, 시대의 변천에 따라 아스팔트시트 방수재, 각종 도막방수재, 벤토나이트 방수재, 가황 및 미가황고무시트 방수재로 변천하면서 방수재가 발전하여 왔고, 종래의 방수재 중에서 고무를 주재료로 한 방수재가 강력한 인장강도와 인열강도 및 높은 신장률 등의 제반 물성이 우수한 장점을 겸비한 방수재로 평가받고 최근에는 널리 사용되고 있었으나 가격이 다소 비싼 단점과 고무 재질을 주재료로 사용하여 내구성을 낮아 장기간 사용시에는 노후되어 방수의 제기능을 발휘하기 어려운 문제점이 있었다.
In addition, waterproofing materials were mainly used as liquid asphalt waterproofing materials in the early stage, and waterproofing materials have been developed asphalt sheet waterproofing materials, various coating films, bentonite waterproofing materials, vulcanized and unvulcanized rubber sheet waterproofing materials, The rubber-based waterproofing material has been widely used as a waterproof material having excellent tensile strength, tear strength and high elongation, and has been recently widely used. However, its price is rather high, and rubber material is used as a main material for durability So that it is difficult to exert its function of waterproofing when it is used for a long period of time.

이렇게 내구성이 낮으면 단기간 사용에도 노후로 인해 제기능을 하지 못하면 일정기간 마다 방수시트를 수리하거나 상황에 따라서는 방수시트를 재설치 하여야 하는 어려움이 있어 불편하였다.
If the durability is low, it is inconvenient to repair the waterproof sheet at a certain period or to reinstall the waterproof sheet depending on the situation if the waterproof sheet can not be used due to aging even in a short period of use.

본 발명은 상술한 종래의 문제점을 해결하기 위한 것으로서, 위와 같이 종래의 방수재와 그것을 이용한 방수공법의 문제점을 해소하고 종래의 방수재와 방수공법의 취약점을 개선하고 보완하기 위하여 안출된 것으로, 지하구조물의 벽면과 바닥, 건물의 벽면과 옥상, 지하차도 등의 콘크리트 구조물의 방수에 용이하고도 간편하게 시공하면서도 하자 없이 안정적으로 방수작업을 유지할 수 있는 새로운 친환경적인 플라스틱 필름 방수시트 및 그것을 이용한 시공방법을 제공하기 위해,Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the conventional waterproofing material and the waterproofing method using the waterproofing material and improving and supplementing the weak points of the conventional waterproofing material and waterproofing method.
