이하, 본 발명의 실시예에 대하여 상세히 설명하기로 한다. Hereinafter, embodiments of the present invention will be described in detail.
먼저, 본 발명의 실시예에 따른 열공법 고무화아스팔트 도막방수재는, 디메틸테레프탈레이트에, 1,6-헥산디아민, 스타이렌, 나프탈렌, 스트레이트아스팔트, 테트라하이드로퓨란, 스타이렌-뷰타디엔-스타이렌 공중합체, 4-메틸피리딘 및 포타슘 피리딘-4-카복실레이트가 150~170℃의 온도에서 용해되어 제조된다.First, the thermal method rubberized asphalt coating waterproofing material according to an embodiment of the present invention is dimethyl terephthalate, 1,6-hexanediamine, styrene, naphthalene, straight asphalt, tetrahydrofuran, styrene-butadiene-styrene The copolymer, 4-methylpyridine and potassium pyridine-4-carboxylate are prepared by dissolving at a temperature of 150 to 170 ℃.
보다 바람직하게는, 본 발명의 바람직한 실시예에 따른 열공법 고무화아스팔트 도막방수재의 제조 방법은, 디메틸테레프탈레이트 100 중량부에, 디메틸테레프탈레이트 100 중량부를 기준으로, 1,6-헥산디아민 70~90 중량부, 스타이렌 60~80 중량부, 나프탈렌 50~70 중량부, 스트레이트아스팔트 40~60 중량부, 테트라하이드로퓨란 30∼50 중량부, 스타이렌-뷰타디엔-스타이렌 공중합체 20~40 중량부, 4-메틸피리딘 10~30 중량부 및 포타슘 피리딘-4-카복실레이트 5∼15 중량부가 첨가되는 단계와, 상기 조성물들이 150~170℃의 온도에서 용해되어 경화시간이 단축된 도막방수재로 제조되는 단계 등을 포함한다.More preferably, the method for producing a rubberized asphalt coating waterproofing material according to a preferred embodiment of the present invention is based on 100 parts by weight of dimethyl terephthalate and 100 parts by weight of dimethyl terephthalate, 1,6-hexanediamine 70~ 90 parts by weight, 60 to 80 parts by weight of styrene, 50 to 70 parts by weight of naphthalene, 40 to 60 parts by weight of straight asphalt, 30 to 50 parts by weight of tetrahydrofuran, 20 to 40 parts by weight of styrene-butadiene-styrene copolymer Parts, 10-30 parts by weight of 4-methylpyridine, and 5-15 parts by weight of potassium pyridine-4-carboxylate are added, and the compositions are dissolved at a temperature of 150-170° C. steps, etc.
디메틸테레프탈레이트는, 상기 조성물들과 반응하여 흡착 및 접착 기능을 제공하는 것으로서, 100 중량부를 초과하는 경우에는 콘크리트 표면에 침투시 셀프레벨링 기능이 커지게 되어 침투 깊이가 오히려 낮아지고 100 중량부에 미만하는 경우에는 도막의 흡착 및 접착 기능이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Dimethyl terephthalate reacts with the compositions to provide adsorption and adhesion functions. When it exceeds 100 parts by weight, the self-leveling function increases when penetrating into the concrete surface, so that the penetration depth is rather low and less than 100 parts by weight. In this case, there is a problem in that the adsorption and adhesion function of the coating film is lowered, so it is preferable to have a limited weight part as described above.
1,6-헥산디아민은, 상기 조성물들과 반응시 도막방수재의 점도 기능을 조절하는 점도 조절 및 결합제로서, 디메틸테레프탈레이트 100 중량부를 기준으로, 90 중량부를 초과하는 경우에는 강한 결합력으로 인하여 점도가 증가되어 오히려 교반 혼합이 저하되고, 70 중량부에 미만하는 경우에는 결합력이 발휘되지 못하여 전반적인 방수성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.1,6-hexanediamine is a viscosity control and binder for controlling the viscosity function of the coating film waterproofing material when reacting with the above compositions. Based on 100 parts by weight of dimethyl terephthalate, when it exceeds 90 parts by weight, the viscosity is high due to strong binding force. As the increase increases, the stirring and mixing decreases, and when it is less than 70 parts by weight, there is a problem in that the bonding force is not exerted and the overall waterproofness is lowered.
스타이렌은, 상기 조성물들의 혼합물인 도막방수재의 표면이 코팅되도록 하는 것으로서, 디메틸테레프탈레이트 100 중량부를 기준으로, 80 중량부를 초과하는 경우에는 도막방수재에 의한 도막방수층의 건조시 코팅 입자들이 커지거나 엉키는 현상이 발생되어 도막방수층의 표면이 고르지 못하게 되어 내구성이 저하되고, 60 중량부에 미만하는 경우에는 도막방수층의 코팅에 따른 피복 효과가 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Styrene is used to coat the surface of the coating film waterproofing material, which is a mixture of the compositions, and when it exceeds 80 parts by weight based on 100 parts by weight of dimethyl terephthalate, the coating particles become large or tangled during drying of the coating film waterproofing layer by the coating film waterproofing material. Since the phenomenon occurs, the surface of the coating film waterproof layer becomes uneven and the durability is reduced, and when it is less than 60 parts by weight, there is a problem that the coating effect according to the coating of the coating film waterproof layer is reduced.
나프탈렌은, 혼화제로서 도막방수재의 투수비와 흡수비를 조절하는 것으로서, 디메틸테레프탈레이트 100 중량부를 기준으로, 70 중량부를 초과하는 경우에는 교반효율이 저하되고, 50 중량부에 미만하는 경우에는 흡수성과 투수성이 증가되어 도막방수층이 쉽게 박리되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Naphthalene, as an admixture, controls the water permeability and absorption ratio of the coating film waterproofing material. Based on 100 parts by weight of dimethyl terephthalate, when it exceeds 70 parts by weight, the stirring efficiency decreases, and when it is less than 50 parts by weight, absorbency and Since there is a problem in that the water permeability is increased and the waterproof coating layer is easily peeled off, it is preferable to have a limited weight portion as described above.
스트레이트아스팔트는, 방수 성능을 제공하고 일예로, KSF 4052 방수공사용 아스팔트가 사용될 수 있으며, 그 중 3종 또는 5종이 사용될 수 있는데, 보다 바람직하게는, 침입도가 80-100mm인 5종을 사용하는 것이 좋고, 3종의 경우 아스팔트에 레진이나 오일함량이 높아 내한성은 우수하나 점착 성능이 5종에 비해 높아 시트의 접합시 향상된 접합력을 제공할 수 있으나, 상대적으로 점착성이 낮은 5종을 사용하는 것이 바람직하다.Straight asphalt provides waterproofing performance and, for example, KSF 4052 asphalt for waterproofing construction may be used, of which 3 or 5 types may be used, and more preferably, 5 types having a penetration of 80-100mm are used. In the case of the three types, the asphalt has a high resin or oil content, so the cold resistance is excellent, but the adhesive performance is higher than that of the five types, so it can provide an improved bonding force when bonding the sheets, but it is better to use the 5 types with relatively low adhesion. desirable.
여기서, 스트레이트아스팔트는, 디메틸테레프탈레이트 100 중량부를 기준으로, 60 중량부를 초과하는 경우에는 점착 성능이 너무 커지게 되어 콘크리트 표면에 도포시 도막방수재 조성물들간 접합이 이루어져 작업성이 저하되고 여름철에 인화 가능성이 높아지게 되며, 40 중량부에 미만하는 경우에는 콘크리트 표면과의 접착성과 방수기능이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Here, when straight asphalt exceeds 60 parts by weight based on 100 parts by weight of dimethyl terephthalate, the adhesive performance becomes too large, so that when applied to the concrete surface, bonding between the coating film waterproofing material compositions is formed, thereby reducing workability and flammability in summer is increased, and if it is less than 40 parts by weight, there is a problem in that adhesion to the concrete surface and waterproof function are deteriorated, so it is good to have the limited parts by weight as described above.
테트라하이드로퓨란은, 상기 조성물들의 교반성능 향상과 접착력을 향상시키는 계면활성 및 침투 기능을 제공하는 유기 용매로서, 디메틸테레프탈레이트 100 중량부를 기준으로, 50 중량부를 초과하는 경우에는 높은 내화학성으로 인하여 조성물들의 교반성이 저하되고, 30 중량부에 미만하는 경우에는 접착 및 코팅 기능이 저하되어 내구성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Tetrahydrofuran is an organic solvent that provides a surface activity and penetration function to improve the stirring performance and adhesion of the compositions. Based on 100 parts by weight of dimethyl terephthalate, when it exceeds 50 parts by weight, the composition due to high chemical resistance Their stirrability is lowered, and when it is less than 30 parts by weight, there is a problem that adhesion and coating functions are lowered and durability is lowered, so it is good to have a limited part by weight as described above.
스타이렌-뷰타디엔-스타이렌 공중합체는, 아스팔트 도막방수재를 통한 방수층의 연성 및 안정성을 향상시키는 가소제 기능을 제공한다.Styrene-butadiene-styrene copolymer provides a plasticizer function that improves the ductility and stability of the waterproofing layer through the asphalt coating waterproofing material.
여기서, 스타이렌-뷰타디엔-스타이렌 공중합체는, 디메틸테레프탈레이트 100 중량부를 기준으로, 40 중량부를 초과하는 경우에는 상기 조성물들의 연성과 안정성이 오히려 저하되어 접착 기능이 저하되고, 20 중량부에 미만하는 경우에는 상기 조성물들의 교반성이 크게 저하되어 접착 기능과 도막 기능이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Here, the styrene-butadiene-styrene copolymer, based on 100 parts by weight of dimethyl terephthalate, when it exceeds 40 parts by weight, the ductility and stability of the compositions are rather deteriorated, so that the adhesive function is reduced, and 20 parts by weight If it is less than, the stirrability of the compositions is greatly reduced, and there is a problem that the adhesion function and the coating film function are deteriorated.
4-메틸피리딘은, 아스팔트 도막방수층의 기계적 특성을 향상시키는 것으로서, 디메틸테레프탈레이트 100 중량부를 기준으로, 30 중량부를 초과하는 경우에는 조성물들의 점도가 너무 높아져 교반성이 저하되고 현장에서의 작업성도 저하되며, 10 중량부에 미만하는 경우에는 혼합물들의 저장 안정성이 저조하게 되어 도막방수층의 접착 강도 등의 기계적 특성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.4-Methylpyridine improves the mechanical properties of the asphalt coating waterproofing layer. Based on 100 parts by weight of dimethyl terephthalate, when it exceeds 30 parts by weight, the viscosity of the compositions becomes too high, and the stirrability is reduced and workability in the field is also reduced. And, if it is less than 10 parts by weight, the storage stability of the mixtures is poor, and there is a problem in that mechanical properties such as adhesive strength of the coating film waterproof layer are deteriorated, so it is preferable to have the limited parts by weight as described above.
포타슘 피리딘-4-카복실레이트는, 도막방수층이 열에 의해 변화되는 것을 억제하기 위하여 감압, 증유 또는 증기 증유와 같은 방법으로 제조된 것으로서, 낮은 연화점과 높은 신장성, 점착성 및 방수성을 제공하며, 디메틸테레프탈레이트 100 중량부를 기준으로, 15 중량부를 초과하는 경우에는 다른 조성물과의 균일한 혼합이 이루어지지 않아 물성이 저하되는 문제점이 있고, 5 중량부에 미만하는 경우에는 도막의 두께 확보가 어려워 흡착성, 인장강도 및 신장률의 특성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Potassium pyridine-4-carboxylate is prepared by a method such as reduced pressure, oil or steam oil to suppress the change of the coating film waterproofing layer by heat, and provides a low softening point and high extensibility, adhesion and water resistance, and dimethyl terephthalate Based on 100 parts by weight of phthalate, if it exceeds 15 parts by weight, there is a problem that the physical properties are deteriorated because uniform mixing with other compositions is not made. Since there is a problem in that the properties of strength and elongation are deteriorated, it is preferable to have a limited weight part as described above.
한편, 본 발명에 있어서, 상기 조성물들은 150℃~170℃의 온도에서 용해되도록 하고 있는데, 조성물들의 적하 또는 교반시 온도가 상기 범위의 온도 보다 낮으면 혼용성이 불량하고 팽윤율이 저하되며 고온안정성도 저하되고, 교반시 온도가 상기 범위의 온도 보다 높으면 과팽윤과 수축성이 발생되는 문제점이 있으므로, 상기와 같은 한정된 용해 온도를 가지는 것이 좋다.On the other hand, in the present invention, the compositions are to be dissolved at a temperature of 150 ℃ ~ 170 ℃, when the temperature during dropping or stirring of the compositions is lower than the temperature in the above range, the miscibility is poor, the swelling rate is reduced, and high temperature stability Also, when the temperature during stirring is higher than the temperature in the above range, there is a problem in that overswelling and shrinkage occur, so it is preferable to have a limited dissolution temperature as described above.
또한, 본 발명의 실시예에 따른 열공법 고무화아스팔트 도막방수재를 이용한 복합 방수 공법에 대해 설명하면 다음과 같다.In addition, the composite waterproofing method using the thermal method rubberized asphalt coating waterproofing material according to an embodiment of the present invention will be described as follows.
먼저, 콘크리트층 표면에 청소 및 평탄화 작업 등과 같은 전처리 작업이 진행된다.First, pretreatment operations such as cleaning and planarization are performed on the surface of the concrete layer.
이후, 콘크리트층 표면에 공지의 프라이머가 도포된다.Thereafter, a known primer is applied to the surface of the concrete layer.
이후, 콘크리트층 표면에 상기와 같은 제조방법에 의해 제조된 열공법 고무화아스팔트 도막방수재가 1-2 mm 두께의 도막방수층으로 시공된다.Thereafter, the thermal rubberized asphalt coating waterproofing material manufactured by the manufacturing method as described above is applied to the surface of the concrete layer as a coating coating waterproofing layer with a thickness of 1-2 mm.
이후, 도막방수층의 상면에 자착식 고무화아스팔트 방수 시트가 부착 시공된다.After that, a self-adhesive rubberized asphalt waterproofing sheet is attached to the upper surface of the waterproofing layer.
