아크릴 점착제, 아크릴 점착제 제조방법 및 이를 이용한 방수시트 이음부위 보강공법{Acrylic adhesive composition, manufacturing method thereof and waterproof method for waterproof sheet joint using thereof} Acrylic adhesive composition, manufacturing method thereof and waterproof method for waterproof sheet joint using thereof

본 발명은 아크릴 점착제 및 이를 이용한 보강공법에 관한 것으로서, 보다 상세하게는, 방수시트간 이음부위 중 오버랩되는 부분에 아크릴 점착제가 겹침 시공되도록 하여 도막방수층 시공시 이음부위로 우레탄 등이 침투되지 않도록 하고 컴파운드와 아크릴 점착제에 의해 방수 성능 및 접착 성능이 향상되도록 할 수 있는 아크릴 점착제, 아크릴 점착제 제조방법 및 이를 이용한 방수시트 이음부위 보강 공법에 관한 것이다. The present invention relates to an acrylic adhesive and a reinforcing method using the same, and more particularly, to prevent the penetration of urethane into the joint during the construction of the coating waterproof layer by overlapping the acrylic adhesive on the overlapping portion of the joint between waterproof sheets. The present invention relates to an acrylic adhesive, a method of manufacturing an acrylic adhesive, and a method of reinforcing a joint portion of a waterproof sheet using the same, which can improve waterproof performance and adhesive performance by a compound and an acrylic adhesive.

일반적으로, 건물의 지붕, 바닥, 지하 주차장 등에는 습기가 건물 내부로 스며드는 것을 방지하기 위해 방수공사를 실시한다. 이러한 방수공사를 수행하는 방수공법에는 도막방수공법, 시트방수공법, 복합방수공법이 있으나 최근에는, 도막방수와 시트방수를 복합화한 복합방수공법이 많이 적용되고 있다.In general, waterproof work is performed on the roof, floor, and underground parking lot of a building to prevent moisture from penetrating into the building. There are a coating waterproofing method, a sheet waterproofing method, and a composite waterproofing method as a waterproofing method for performing such waterproofing work, but recently, a composite waterproofing method in which a coating waterproofing and sheet waterproofing are combined is widely applied.

복합방수공법에 이용되는 방수시트는 통상적으로 방수재료로 형성된 방수층과 상부표층을 부직포로 처리되도록 제작되며, 다만 다양한 기능을 부여하기 위해 다양한 재료를 복합하여 제작되기도 한다. 복합기능의 방수시트로는 스티로폼 등의 통상의 단열재를 방수층과 일체화한 단열 방수시트가 있으나, 이러한 단열 방수시트는 통상의 단열재를 그대로 적용했던 관계로 두께가 두꺼운 단점이 있다. The waterproof sheet used in the composite waterproofing method is usually manufactured so that the waterproof layer formed of a waterproof material and the upper surface layer are treated with a nonwoven fabric, but it is also manufactured by combining various materials to impart various functions. As a composite waterproof sheet, there is an insulating waterproof sheet in which a conventional insulating material such as styrofoam is integrated with a waterproof layer, but this insulating waterproof sheet has a disadvantage of having a thick thickness due to the fact that the conventional insulating material is applied as it is.

이에, 상기와 같은 문제점을 해결하기 위하여, 등록특허 10-0983618호 등에, 두께가 얇고 새로운 단열 방수시트로서 알루미늄 피막 방수시트가 개시된 바 있다.Accordingly, in order to solve the above problems, an aluminum film waterproof sheet has been disclosed as a new insulating waterproof sheet having a thin thickness in Korean Patent No. 10-0983618 or the like.

여기서, 종래의 방수시트는, 하부표층이 알루미늄에 의한 열반사막으로 구성되고, 중간층이 PE폼을 포함한 방수층으로 구성되며, 상부표층이 부직포로 구성되고, 상기 부직포에 의한 상부표층의 아래층으로 부직포에 열융착된 필름층이 구성된 것으로서, 상기 필름층이 알루미늄, 폴리프로필렌, 폴리에스테르, 폴리염화비닐 중 어느 하나로 마련되고, 상기 부직포와 필름층이 각각 동일한 방향으로 상기 중간층의 방수층보다 연장 돌출된 날개부를 가지는 한편, 상기 필름층의 날개부 아래에 날개접착층과 이형지가 마련되도록 하고 있다.Here, in the conventional waterproof sheet, the lower surface layer is composed of a heat reflective film made of aluminum, the middle layer is composed of a waterproof layer including PE foam, the upper surface layer is composed of a non-woven fabric, and the upper surface layer is formed of the non-woven fabric. A heat-sealed film layer is formed, wherein the film layer is provided with any one of aluminum, polypropylene, polyester, and polyvinyl chloride, and the non-woven fabric and the film layer are respectively extended in the same direction than the waterproof layer of the intermediate layer. On the other hand, the wing adhesive layer and release paper are provided under the wing portion of the film layer.

그러나 상기와 같은 종래의 방수시트는, 인접한 방수시트 상호간의 이음부위를 접합시켜주는 날개부가 단순히 부직포의 일측부 상측단에 일부분이 접합된 상태에서 소정면적을 가지면서 나머지 부분이 연장된 구조를 가지고 있다.However, the conventional waterproof sheet as described above has a structure in which the wing portions that bond the joints between adjacent waterproof sheets have a predetermined area while the remaining portions are extended while a portion is simply joined to the upper end of one side of the nonwoven fabric. have.

따라서 인접한 방수시트 상호간의 이음부위를 접합하는 경우, 어느 하나의 부직포 일측부 상측단에 일부분이 접합된 날개부의 나머지 부분이 다른 하나의 부직포 타측부 상측단에 소정면적을 가지면서 커버한 상태로 접합되는 구조를 가지게 된다. Therefore, in the case of joining the joints between adjacent waterproof sheets, the rest of the wing part, which is partially joined to the upper end of one nonwoven fabric, is joined while having a predetermined area on the upper end of the other nonwoven fabric. It will have a structure that becomes.

이에, 상기와 같은 구조로 인접한 방수시트의 이음부위가 접합되는 경우에는, 바람이 불거나 작은 충격에도 상기 날개부가 쉽게 들뜨거나 접히기 때문에 접합 상태의 내구성이 크게 저하되어 해당 부위의 방수기능이 취약해지는 문제점이 있다.Accordingly, when the joints of adjacent waterproof sheets are joined with the structure as described above, the wing parts are easily lifted or folded even when the wind blows or a small impact, so the durability of the joined state is greatly reduced, and the waterproof function of the corresponding part is weak. There is a problem of losing.

따라서 본 발명의 목적은 방수시트간 이음부위가 오버랩되는 구조로 접합시 어느 하나의 방수시트 오버랩 부분에 다른 하나의 방수시트 하부표층 일측에 도포된 아크릴 점착제가 겹침 시공되도록 하여 상부표층의 상부에 도막방수층 시공시 이음부위로 도막방수재가 침투되지 않도록 하고 바탕면에 접착되는 하부표층 하부의 컴파운드와 아크릴 점착제에 의해 방수 성능 및 접착 성능이 향상되도록 할 수 있는 아크릴 점착제, 아크릴 점착제 제조방법 및 이를 이용한 방수시트 이음부위 방수공법를 제공하는 것이다.Therefore, an object of the present invention is to overlap the joints between the waterproof sheets. When bonding, the acrylic adhesive applied on one side of the lower surface layer of the other waterproof sheet is overlapped with the overlapping part of the other waterproof sheet when bonding. Acrylic adhesive, acrylic adhesive manufacturing method, and waterproofing using the same, which prevents penetration of the coating waterproofing material into the joint when waterproofing layer construction, and improves waterproofing performance and adhesion by the compound and acrylic adhesive under the lower surface layer adhered to the base surface. It is to provide a waterproofing method for the seat joint.
