Description
본 발명은 이액형 폴리우레탄 도막 방수재 조성물 및 이의 제조방법에 관한 것으로, 보다 상세하게는 도막 내 수산기를 잔존하게 설계하여 우수한 점착성을 갖는 이액형 폴리우레탄 도막 방수재 조성물 및 이의 제조방법에 관한 것이다.The present invention relates to a two-component polyurethane waterproofing composition and a method for producing the same, and more specifically, to a two-component polyurethane waterproofing composition having excellent adhesiveness by designing to retain hydroxyl groups in the coating, and a method for producing the same.
건축물의 지붕, 바닥, 지하 주차장, 욕실 또는 화장실 등에는 빗물, 생활용수 누수를 방지하기 위하여 방수 공사를 실시하고 있다.Waterproofing work is being carried out on roofs, floors, underground parking lots, bathrooms, or toilets of buildings to prevent rainwater and domestic water leakage.
방수 공사는 다양한 소재들의 누수에 의한 부식 및 균열 발생을 방지하고 수밀성을 향상시켜 장기간 내구성을 확보하기 위해 실시되고 있다.Waterproofing work is carried out to prevent corrosion and cracking caused by water leakage in various materials and to improve watertightness to ensure long-term durability.
방수 공사는 현장 여건에 부합하게 도막 방수공법, 시트 방수공법, 복합방수공법 등 여러 방수 공법이 적용될 수 있다.Waterproofing construction can be applied using various waterproofing methods such as film waterproofing, sheet waterproofing, and composite waterproofing depending on the on-site conditions.
대부분의 방수 공법에서 방수 요구되는 층인 피도면과 방수층 간의 접착력에 따라 피도면의 방수 내구성이 현저하게 달라지는 것으로 보고되어 있다.It has been reported that in most waterproofing methods, the waterproof durability of the surface to be coated significantly varies depending on the adhesive strength between the waterproofing layer and the surface to be coated, which is the waterproofing layer required.
폴리우레탄은 치밀한 조직 및 우수한 방수성으로 도막 방수공법에 많이 사용되고 있다.Polyurethane is widely used in waterproofing coating methods due to its dense structure and excellent waterproofing properties.
폴리우레탄 방수재는 액상 형태의 재료로 건축물의 피도면에 도포 시 경화되면서 도막 방수층을 형성하여 이음매 없이 시공이 가능하고 전면에 접착되어 부착성능이 우수한 특징이 있다.Polyurethane waterproofing material is a liquid material that forms a waterproofing film layer when applied to the surface of a building, allowing construction without joints and has the characteristic of excellent adhesion as it adheres to the entire surface.
이러한 폴리우레탄 도막 방수재는 크게 습기경화형인 1액형과 화학반응형인 2액형으로 분류될 수 있으며, 현재 2액형 폴리우레탄 방수재가 활발히 사용되고 있는 추세이다.These polyurethane waterproofing coatings can be broadly classified into one-component moisture-curing and two-component chemical reaction types, and two-component polyurethane waterproofing materials are currently being actively used.
한편, 최근 건축물 구조가 더욱 복잡해짐에 따라 건축물에 적용되는 소재가 다양해지고 있는 실정이다.Meanwhile, as building structures have become more complex, the materials used in buildings have become more diverse.
종래기술에 있어서 콘크리트, PVC, PE, 철재, 스테인레스 등과 같은 소재들에 방수 공사를 진행할 시 별도의 하도 도장이 필요한 것으로 알려져 있다.It is known that in conventional technology, when waterproofing materials such as concrete, PVC, PE, steel, and stainless steel, a separate primer coating is required.
이러한 하도 도장을 진행함에 따라 공정 단계 및 공정 시간이 증가하여 시공이 용이하지 않고 인건비, 자재 등의 비용이 증가하는 문제점이 있다.As this type of undercoat painting is carried out, the process steps and process time increase, making construction difficult and increasing the costs of labor and materials.
이러한 문제를 해결하기 위해, 본 출원인은 각고의 노력과 여러 연구를 통해 도막 내 수산기를 잔존하게 설계하여 우수한 점착성을 갖는 이액형 폴리우레탄 도막 방수재 조성물 및 이의 제조방법을 획득하여 본 발명을 완성하게 되었다.To solve these problems, the present applicant, through painstaking efforts and extensive research, designed a two-component polyurethane coating waterproofing composition with excellent adhesiveness by leaving hydroxyl groups in the coating film and obtained a method for producing the same, thereby completing the present invention.
상기한 바와 같은 종래의 문제점을 해결하기 위한 본 발명은, 도막 내 수산기를 잔존하게 설계하여 우수한 점착성을 갖는 이액형 폴리우레탄 도막 방수재 조성물을 제공하는 데에 목적이 있다.The purpose of the present invention, in order to solve the above-mentioned conventional problems, is to provide a two-component polyurethane waterproofing composition having excellent adhesiveness by designing to leave hydroxyl groups in the coating.

<평가예 1> 이액형 폴리우레탄 도막 방수재 물성 평가<Evaluation Example 1> Evaluation of the properties of a two-component polyurethane waterproofing film
상기 상술한 실시예 1 및 비교예 1 내지 3으로 제조한 이액형 폴리우레탄 도막 방수재의 물성을 평가하였다. 상기 상술한 주제부와 경화제부의 중량비로 혼합된 혼합물을 24시간 후 경화상태를 확인하였다. 이때 경화상태 확인 방법은 고화건조 상태 확인 방법으로 수행하였다. 또한, 24시간이 경과된 혼합물은 만능재료시험기를 사용하여 인장강도 및 신장율을 평가하였다. 평가방법은 KS F 3211 건설용 도막 방수재 평가방법을 적용하였다. 평가 결과는 하기 [표 2]와 같다.The properties of the two-component polyurethane waterproofing film prepared by the above-described Example 1 and Comparative Examples 1 to 3 were evaluated. The mixture mixed in the weight ratio of the main part and the hardener part described above was checked for curing after 24 hours. At this time, the curing state was checked by the solidification and drying state check method. In addition, the tensile strength and elongation of the mixture after 24 hours were evaluated using a universal material testing machine. The evaluation method applied the KS F 3211 construction coating waterproofing material evaluation method. The evaluation results are as follows [Table 2].
상기 [표 2]를 참고하면, 실시예 1에서 폴리우레탄 도막 방수재 조성물은 24시간 후 경화상태가 양호하였고, 인장강도 및 파단시 신장율은 각각 0.7 N/mm2, 1600% 이었다. 비교예 1에서 폴리우레탄 도막 방수재 조성물은 24시간 후 경화가 완전히 이루어지지 않아 손에 묻어났고, 이에 인장강도 및 신장율 측정용 시편을 제작할 수 없었다. 비교예 2에서 폴리우레탄 도막 방수재 조성물은 24시간 후 경화되지 않은 상태이었다. 비교예 3에서 폴리우레탄 도막 방수재 조성물은 24시간 후 경화가 완전히 이루어지지 않아 손에 묻어났고, 이에 인장강도 및 신장율 측정용 시편을 제작할 수 없었다. 따라서, 상기 상술한 바와 같이, 주제부의 폴리프로필렌 글리콜의 중량평균분자량이 5,000이고, 경화제부의 폴리프로필렌 글리콜의 중량평균분자량이 6,000이며, NCO/OH의 당량비가 0.8일 때, 경화성이 양호하고 인장강도 및 신장율이 측정 가능한 폴리우레탄 도막 방수재 조성물을 얻을 수 있었다.Referring to the above [Table 2], in Example 1, the polyurethane coating waterproofing composition was in a good cured state after 24 hours, and the tensile strength and elongation at break were 0.7 N/ mm2 and 1600%, respectively. In Comparative Example 1, the polyurethane coating waterproofing composition was not completely cured after 24 hours and thus stuck to the hands, and thus specimens for measuring the tensile strength and elongation could not be produced. In Comparative Example 2, the polyurethane coating waterproofing composition was not cured after 24 hours. In Comparative Example 3, the polyurethane coating waterproofing composition was not completely cured after 24 hours and thus stuck to the hands, and thus specimens for measuring the tensile strength and elongation could not be produced. Therefore, as described above, when the weight average molecular weight of the polypropylene glycol of the main body part was 5,000, the weight average molecular weight of the polypropylene glycol of the curing agent part was 6,000, and the equivalence ratio of NCO/OH was 0.8, a polyurethane coating waterproofing composition having good curability and measurable tensile strength and elongation was obtained.
<평가예 2> 이액형 폴리우레탄 도막 방수재 물성 평가<Evaluation Example 2> Evaluation of the properties of a two-component polyurethane waterproofing film
상기 상술한 실시예 1 내지 3과 비교예 4로 제조한 이액형 폴리우레탄 도막 방수재의 물성을 평가하였다. 상기 상술한 주제부와 경화제부의 중량비로 혼합된 혼합물을 24시간 후 경화상태를 확인하였다. 이때 경화상태 확인 방법은 고화건조 상태 확인 방법으로 수행하였다. 24시간이 경과된 혼합물은 만능재료시험기를 사용하여 90°박리 시험(90°peel off test)을 수행하였다. 소지면의 소재는 PVC, PE, 스테인레스, 락보드로 선정하였다. 각각의 소지면에 실시예 1 내지 3과 비교예 4를 도장한 후 부직포를 도포하여 시편을 제작하였다. 시험종료 후 박리 길이는 소지면과 박리 시 길이를 측정하였다. 24시간이 경과된 혼합물은 재점착성 시험을 수행하였다. 소지면의 소재는 PVC, PE, 스테인레스, 락보드로 선정하였다. 100 mm x 100 mm 크기인 소지면에 600g 축을 고정시킨 하부 시험체와 동일한 크기인 소지면 상부 시험체를 준비하였다. 각각의 소재 하부 시험체에 실시예 1 내지 3과 비교예 4를 도장한 후 상부 시험체를 덮어 고정시켰다. 고정된 전체 시험체를 1주일 경화시킨 후 강제로 하부 시험체를 박리시키고 60초 뒤 재부착시켰다. 상부 시험체를 들고 그 순간부터 초시계로 하부 시험체가 탈락할 때까지의 시간을 측정하였다. 평가 결과는 하기 [표 3]과 같다.The properties of the two-component polyurethane waterproofing coating material manufactured by the above-described Examples 1 to 3 and Comparative Example 4 were evaluated. The mixture, in which the weight ratio of the main part and the hardener part was mixed as described above, was checked for the curing state after 24 hours. At this time, the curing state was checked by the solidification and drying state check method. The mixture after 24 hours was subjected to a 90° peel off test using a universal material testing machine. The materials of the supporting surface were selected as PVC, PE, stainless steel, and rock board. After Examples 1 to 3 and Comparative Example 4 were painted on each supporting surface, a non-woven fabric was applied to produce a specimen. After the test was completed, the peeling length was measured as the length at the time of peeling and the supporting surface. The mixture after 24 hours was subjected to a re-adhesion test. The materials of the supporting surface were selected as PVC, PE, stainless steel, and rock board. A lower specimen with a 600 g shaft fixed to a 100 mm x 100 mm surface and an upper specimen of the same size were prepared. Each of the lower specimens was painted with Examples 1 to 3 and Comparative Example 4, and then the upper specimen was covered and fixed. After the entire fixed specimen was hardened for one week, the lower specimen was forcibly peeled off and reattached after 60 seconds. The upper specimen was lifted and the time until the lower specimen fell off was measured using a stopwatch. The evaluation results are as shown in [Table 3] below.

상기 [표 3]을 참고하면, 실시예 1 내지 3에서 폴리우레탄 도막 방수재 조성물은 24시간 후 경화상태가 양호하였다. 반면, 비교예 4에서 폴리우레탄 도막 방수재 조성물은 24시간 후 경화가 완전히 이루어지지 않아 손에 묻어났고, 이에 90°박리 시험 및 재점착성 시험 진행이 불가하였다. 실시예 1에서 폴리우레탄 도막 방수재 조성물은 PVC, PE, 스테인레스, 락보드에 건전하게 도포되었고, 90°박리 시험 후 박리 길이는 35 mm 수준이었다. 재점착성 시험 결과, 상기 상술한 모든 소재에서 도포된 폴리우레탄 조성물이 탈락할 때까지 걸린 시간은 70초 이상이었다. 실시예 2에서 폴리우레탄 도막 방수재 조성물은 PVC, PE, 스테인레스, 락보드에 건전하게 도포되었고, 90°박리 시험 후 박리 길이는 15 mm 수준이었다. 재점착성 시험 결과, 상기 상술한 모든 소재에서 도포된 폴리우레탄 조성물이 탈락할 때까지 걸린 시간은 35초 수준이었다. 실시예 3에서 폴리우레탄 도막 방수재 조성물은 PVC, PE, 스테인레스, 락보드에 건전하게 도포되었고, 90°박리 시험 후 박리 길이는 3 mm 수준이었다. 재점착성 시험 결과, 상기 상술한 모든 소재에서 도포된 폴리우레탄 조성물이 탈락할 때까지 걸린 시간은 3초 수준이었다. 따라서, 실시예 1 내지 3에서 NCO/OH의 당량비가 0.8이상일 때 상기 상술한 모든 소재에서 점착력이 우수함을 확인하였고, 상세하게는, NCO/OH의 당량비가 증가할수록 점착력이 감소하는 경향이 나타났다.Referring to the above [Table 3], in Examples 1 to 3, the polyurethane coating waterproofing composition was in a good cured state after 24 hours. On the other hand, in Comparative Example 4, the polyurethane coating waterproofing composition did not completely cure after 24 hours and left residue on the hand, and thus a 90° peel test and a re-adhesion test could not be performed. In Example 1, the polyurethane coating waterproofing composition was soundly applied to PVC, PE, stainless steel, and rockboard, and the peeling length after the 90° peeling test was about 35 mm. As a result of the re-adhesion test, the time taken for the applied polyurethane composition to peel off from all of the materials described above was 70 seconds or more. In Example 2, the polyurethane coating waterproofing composition was soundly applied to PVC, PE, stainless steel, and rockboard, and the peeling length after the 90° peeling test was about 15 mm. As a result of the re-adhesion test, the time taken for the polyurethane composition applied to peel off from all of the materials described above was approximately 35 seconds. In Example 3, the polyurethane coating waterproofing material composition was soundly applied to PVC, PE, stainless steel, and rock board, and the peeling length after a 90° peeling test was approximately 3 mm. As a result of the re-adhesion test, the time taken for the polyurethane composition applied to peel off from all of the materials described above was approximately 3 seconds. Therefore, it was confirmed that the adhesion was excellent for all of the materials described above when the equivalence ratio of NCO/OH was 0.8 or higher in Examples 1 to 3, and specifically, the adhesion tended to decrease as the equivalence ratio of NCO/OH increased.

The mixture, in which the weight ratio of the main part and the hardener part described above was mixed, was checked for curing status after 24 hours. At this time, the method for checking the curing status was performed by a method for checking the solidification and drying status. The polyurethane waterproofing film composition of the thixotropic type in Example 4 had a good curing status after 24 hours.
