Description
본 발명은 통기성 코팅제의 제조방법 및 통기성 코팅제가 코팅된 복합방수용 보강재에 관한 것으로서, 보다 상세하게는 폴리에틸렌에 폴리프로필렌, 하이드록시아세틱에시드, 벤질브로마이드, 카복실릭에시드, 메틸마그네슘아이오다이드 및 폴리에틸렌테레프탈레이트를 용융시킨 후 다공성실리카, 탈크 및 탄산칼슘을 혼합하여 통기성 코팅제를 제조하고 소정 두께의 부직포 한쪽면에 코팅한 복합방수용 통기성 보강재를 통하여 구조물의 바닥면에 부착되고 도막방수재의 도포 시공후 부풀음을 방지할 수 있는 통기성 코팅제의 제조방법 및 통기성 코팅제가 코팅된 복합방수용 보강재에 관한 것이다. The present invention relates to a method for manufacturing a breathable coating agent and a composite waterproofing reinforcement material coated with a breathable coating agent, and more specifically, to polyethylene, polypropylene, hydroxyacetic acid, benzyl bromide, carboxylic acid, methylmagnesium iodide, and polyethylene. After melting terephthalate, a breathable coating is prepared by mixing porous silica, talc, and calcium carbonate. It is attached to the bottom of the structure through a breathable reinforcing material for composite waterproofing coated on one side of a non-woven fabric of a certain thickness, and swells after application of the coating waterproofing material. It relates to a method of manufacturing a breathable coating that can prevent and a composite waterproofing reinforcement material coated with a breathable coating.
일반적으로, 건축물 또는 구조물을 형성하는 콘크리트나 모르타르 등과 같은 무기질계 재료는 시멘트의 수화 반응에 따른 수화열 또는 각종 진동 등으로 균열이 발생할 수 있으며, 이로 인해 방수재가 파단되어 누수나 결로 현상이 발생되고 누수 현상 발생에 의해 구조물의 내구성이 더욱 약화되고 노화가 촉진되는 구조적 단점이 발생된다. In general, inorganic materials such as concrete or mortar that form buildings or structures may crack due to hydration heat or various vibrations due to the hydration reaction of cement, which causes the waterproofing material to break, causing water leakage or condensation. This phenomenon further weakens the durability of the structure and causes structural shortcomings that accelerate aging.
이에, 상기와 같은 콘크리트 건축물 또는 구조물에 발생하는 균열 등을 방지 또는 보수하기 위해 구조물의 옥상, 외벽 등의 외부에 방수공사가 실시되고 있으며, 대표적으로 방수시트를 이용한 방수시트방수공법, 각종 도막방수제를 이용한 도막방수공법 및 방수시트와 도막방수제를 함께 이용한 복합방수공법 등이 있다.Accordingly, in order to prevent or repair cracks occurring in concrete buildings or structures as described above, waterproofing work is being carried out on the exterior of structures such as rooftops and exterior walls. Representative examples include the waterproofing sheet waterproofing method using waterproof sheets and various coating waterproofing agents. There is a film waterproofing method using and a composite waterproofing method using a waterproof sheet and a film waterproofing agent together.
그러나 최근에는 방수 시공이 복잡하고 시간이 오래 걸리는 도막방수공법 대신에, 방수 시공을 보다 간편히 하고 시공 기간도 크게 단축시키기 위하여 방수시트방수공법 또는 복합방수공법이 주로 이용되고 있다. However, recently, instead of the coating film waterproofing method, which is complicated and time-consuming, the waterproofing sheet waterproofing method or the composite waterproofing method is mainly used to make waterproofing construction simpler and significantly shorten the construction period.
여기서, 방수시트방수공법은, 구조물의 옥상 등의 바닥면에 방수시트를 부착하여 방수층을 형성하는 공법으로, 구체적으로 설명하면 PVC 시트나 고무화 아스팔트 시트 등의 일정 규격의 방수시트를 구조물의 바닥면에 펼쳐서 시공하는 공법이다.Here, the waterproof sheet waterproofing method is a method of forming a waterproof layer by attaching a waterproof sheet to the bottom surface of the roof of a structure, etc. To be specific, a waterproof sheet of a certain standard such as a PVC sheet or rubberized asphalt sheet is attached to the bottom of the structure. It is a construction method that involves spreading it on a surface.
또한, 복합방수공법은, 방수시트를 건물 옥상 등의 구조물의 바닥면에 부착 설치하여 1차 방수층을 형성시킨 후, 방수시트의 상면에 도막방수재를 도포하여 2차 방수층을 형성시키는 공법이다.In addition, the composite waterproofing method is a method of forming a primary waterproofing layer by attaching a waterproofing sheet to the bottom of a structure such as a building rooftop, and then applying a coating waterproofing material to the upper surface of the waterproofing sheet to form a secondary waterproofing layer.
그러나 방수시트방수공법은 방수시트만으로 방수층을 형성함에 따라 내구성이 크게 저하되어 방수 수명이 짧고, 복합방수공법은 방수시트의 경우 통기성을 제공하지 못하고 오로지 방수 기능만을 제공하기 때문에 도막방수재의 시공시 부풀음이 발생되어 방수층이 쉽게 박리되는 문제점이 있다. However, as the waterproof sheet waterproofing method forms a waterproof layer with only the waterproof sheet, the durability is greatly reduced and the waterproofing lifespan is short, and the composite waterproofing method does not provide breathability in the case of waterproof sheets and only provides a waterproof function, so the coated waterproofing material swells during construction. This causes the waterproof layer to easily peel off.
따라서 본 발명의 목적은 폴리에틸렌에 폴리프로필렌, 하이드록시아세틱에시드, 벤질브로마이드, 카복실릭에시드, 메틸마그네슘아이오다이드 및 폴리에틸렌테레프탈레이트를 용융시킨 후 다공성실리카, 탈크 및 탄산칼슘을 혼합하여 통기성 코팅제를 제조하고 소정 두께의 부직포 한쪽면에 코팅한 복합방수용 통기성 보강재를 통하여 구조물의 바닥면에 부착되고 도막방수재의 도포 시공후 부풀음을 방지할 수 있는 통기성 코팅제의 제조방법 및 통기성 코팅제가 코팅된 복합방수용 보강재를 제공하는 것이다.Therefore, the purpose of the present invention is to melt polypropylene, hydroxyacetic acid, benzyl bromide, carboxylic acid, methylmagnesium iodide, and polyethylene terephthalate in polyethylene, and then mix porous silica, talc, and calcium carbonate to create a breathable coating agent. A method of manufacturing a breathable coating that is attached to the bottom of a structure through a breathable composite waterproofing reinforcing material manufactured and coated on one side of a non-woven fabric of a predetermined thickness and can prevent swelling after application of a film waterproofing material, and a composite waterproofing reinforcing material coated with a breathable coating is to provide.

여기서, 폴리에틸렌은, 상기 조성물들의 중량부에 대하여 100중량부가 혼합되는데, 상기 중량부를 벗어나는 경우에는 각 조성물들에 포함된 다공체 또는 고형분들의 중량부에 따른 균열 내부의 침투력, 충전도 및 점도 등의 특성이 변화되어 통기성 외에, 시공성 및 내알칼리성과 내수성 등이 저하되는 문제점이 있으므로, 상기와 같은 한정된 범위의 중량부를 가지는 것이 바람직하다.Here, 100 parts by weight of polyethylene is mixed with respect to the parts by weight of the compositions, and if it exceeds the weight part, the properties such as penetration power, filling degree, and viscosity inside the crack according to the weight part of the porous body or solid contained in each composition. Due to this change, there is a problem that workability, alkali resistance, water resistance, etc., in addition to breathability, are reduced, so it is preferable to have the weight part within the limited range as described above.
폴리프로필렌은, 상기 조성물들이 혼합되어 제조된 코팅제의 접착 강도를 높이기 위한 것으로서, 특히 요소가가 2.0 이하, 검화가가 190-200인 경우 접착강도가 매우 우수하게 되므로, 이에 대한 특성을 가지는 것이 좋다.Polypropylene is used to increase the adhesive strength of a coating prepared by mixing the above compositions. In particular, when the urea value is 2.0 or less and the saponification value is 190-200, the adhesive strength is very excellent, so it is good to have these properties.
여기서, 폴리프로필렌은, 폴리에틸렌 100중량부에 대하여 70~90중량부가 첨가되는데, 90중량부 보다 많이 첨가되면 점도가 높아져 작업성이 저하되고, 70중량부 보다 적게 첨가되면 접착력과 제조 안정성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다.Here, 70 to 90 parts by weight of polypropylene is added to 100 parts by weight of polyethylene. If more than 90 parts by weight is added, the viscosity increases and workability deteriorates, and if less than 70 parts by weight is added, adhesion and manufacturing stability deteriorate. Since there is a problem, it is desirable to have a limited weight portion as described above.
하이드록시아세틱에시드는, 상기 조성물들이 혼합된 후 부직포의 코팅시 부직포 내부로 소정 깊이 침투되도록 하는 것으로서, 폴리에틸렌 100중량부에 대하여 60~80중량부가 첨가되는데, 80중량부 보다 많이 첨가되면 부직포 깊은 곳까지 침투되어 방수 기능이 너무 저하되고, 60중량부 보다 적게 첨가되면 부직포 겉에만 침투되어 쉽게 박리되는 문제점이 있으므로, 상기와 같은 한정된 범위의 중량부를 가지는 것이 바람직하다.Hydroxyacetic acid is used to penetrate to a certain depth into the nonwoven fabric when coating the nonwoven fabric after the above compositions are mixed, and is added in an amount of 60 to 80 parts by weight per 100 parts by weight of polyethylene. If more than 80 parts by weight is added, the nonwoven fabric penetrates deep into the nonwoven fabric. Because it penetrates to all areas, the waterproof function is severely reduced, and if less than 60 parts by weight is added, it penetrates only into the surface of the nonwoven fabric and is easily peeled off. Therefore, it is preferable to have the weight part within the limited range as described above.
벤질브로마이드는, 부직포에 코팅된 후 구조물 표면에 부착시 접착 강도 향상과 들뜸 및 분리를 억제하는 것으로서, 폴리에틸렌 100중량부에 대햐여 50~70중량부가 첨가되는데, 70중량부 보다 많이 첨가되면 부직포의 들뜸 현상과 분리 현상이 오히려 커지게 되어 통기성이 저하되고, 50중량부 보다 적게 첨가되면 보습성과 투습성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다.Benzyl bromide improves adhesive strength and suppresses lifting and separation when coated on non-woven fabric and attached to the surface of the structure. Benzyl bromide is added in an amount of 50 to 70 parts by weight per 100 parts by weight of polyethylene. If more than 70 parts by weight is added, it can cause damage to the non-woven fabric. The floating phenomenon and separation phenomenon are rather increased, which reduces breathability, and if less than 50 parts by weight is added, there is a problem that moisture retention and moisture permeability are reduced, so it is preferable to have the limited weight part as described above.
카복실릭에시드는, 부직포와 구조물 표면과의 접착 강도를 향상시키는 기능을 제공하는 것으로서, 폴리에틸렌 100중량부에 대하여 40~60중량부가 첨가되는데, 60중량부 보다 많이 첨가되면 부직포와 구조물 표면과의 접착력은 증대되지만 다른 조성물들과의 교반성이 저하되고, 40중량부 보다 적게 첨가되면 부직포와 구조물 표면과의 접착력이 저하되고 이로 인하여 부풀음과 들뜸 현상이 커지게 되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다.Carboxylic acid provides the function of improving the adhesive strength between the nonwoven fabric and the structure surface. 40 to 60 parts by weight is added per 100 parts by weight of polyethylene. If more than 60 parts by weight is added, the adhesive strength between the nonwoven fabric and the structure surface is reduced. is increased, but the mixing ability with other compositions is reduced, and if less than 40 parts by weight is added, the adhesion between the nonwoven fabric and the surface of the structure is reduced, which increases swelling and lifting, so the limited weight as described above Having wealth is desirable.
메틸마그네슘아이오다이드는, 상기 첨가물이 용융된 혼합물에 다공성실리카, 탈크 및 탄산칼슘이 첨가된 후 사용성과 교반성을 향상시키는 것으로서, 폴리에틸렌 100중량부에 대하여 30~50중량부가 첨가되는데, 50중량부 보다 많이 첨가되면 조성물들의 상용성이 극대화되어 혼합성이 오히려 저하되고, 30중량부 보다 적게 첨가되면 조성물들의 상용성이 저하되어 통기성과 투수비가 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다.Methylmagnesium iodide improves usability and agitation after porous silica, talc, and calcium carbonate are added to the mixture in which the above additives are melted, and is added in an amount of 30 to 50 parts by weight per 100 parts by weight of polyethylene, 50 parts by weight. If more is added, the compatibility of the compositions is maximized and the miscibility is rather lowered, and if less than 30 parts by weight is added, the compatibility of the compositions is reduced and the breathability and water permeability ratio are lowered. Therefore, it is better to have the above limited parts by weight. desirable.
폴리에틸렌테레프탈레이트는, 상기 코팅제가 소정의 경도를 가지도록 하여 방수층의 내구성이나 내스크래치성 등의 기능을 제공하는 것으로서, 폴리에틸렌 100중량부에 대하여 20~40중량부가 첨가되는데, 40중량부 보다 많이 첨가되면 코팅층 또는 방수층의 경도가 너무 강하게 되어 들뜸 현상에 의한 부착 강도가 저하되고, 20중량부 보다 적게 첨가되면 코팅층 또는 방수층의 경도가 너무 약해져 충격이나 시공중 접힘 동작시 찢어지게 되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다.Polyethylene terephthalate provides functions such as durability and scratch resistance of the waterproof layer by ensuring that the coating agent has a predetermined hardness. 20 to 40 parts by weight is added per 100 parts by weight of polyethylene, but more than 40 parts by weight is added. If this is done, the hardness of the coating layer or waterproofing layer becomes too strong and the adhesion strength due to the lifting phenomenon decreases, and if less than 20 parts by weight is added, the hardness of the coating layer or waterproofing layer becomes too weak and there is a problem of tearing during impact or folding during construction. It is preferable to have a limited weight part such as.

Additives containing 30 to 50 parts by weight of iodide and 20 to 40 parts by weight of polyethylene terephthalate are melted at 250°C to 300°C for 3 to 5 hours. If the temperature and time are outside the above range, the solubility, reactivity, and Since the binding force of colloidal particles decreases, it is preferable to use the above temperature and time.
다공성실리카는, 부직포와 구조물의 표면 사이에 형성되는 방수층에 통기성이 제공되도록 하는 것으로서, 입도 20-50nm, 비표면적 640ㅁ60m2/g 및 밀도 ≤160의 특성을 가지는 미세다공성 물질인 것이 좋으며, 폴리에틸렌 100중량부에 대하여 10~30중량부가 첨가되는데, 30중량부 보다 많이 첨가되면 통기성은 증대되지만 결합력이 저하되어 들뜸 현상이 커지게 되고, 10중량부 보다 적게 첨가되면 통기성이 저하되어 오히려 들뜸 현상이 커지게 되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다.Porous silica is used to provide breathability to the waterproof layer formed between the non-woven fabric and the surface of the structure, and is preferably a microporous material with a particle size of 20-50 nm, a specific surface area of 640ㅁ60m2/g, and a density of ≤160, and is preferably polyethylene. 10 to 30 parts by weight are added per 100 parts by weight. If more than 30 parts by weight is added, breathability increases, but the binding force decreases and the lifting phenomenon increases. If less than 10 parts by weight are added, the breathability decreases and the lifting phenomenon increases. Since there is a problem in that it becomes large, it is desirable to have a limited weight portion as described above.
탈크는, 코팅제에 소정의 고형분이 첨가되도록 하여 통기성이 향상되도록 하는 것으로서, 폴리에틸렌 100중량부에 대하여 5~15중량부가 첨가되는데, 15중량부 보다 많이 첨가되면 다공성실리카 사이의 공극이 모두 충전되어 통기성이 저하되고, 5중량부 보다 적게 첨가되면 다공성실리카 사이의 공극이 채워지는 것이 미비하여 통기성은 극대화되지만 결합력이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다.Talc is used to improve breathability by adding a certain amount of solid content to the coating agent. It is added in an amount of 5 to 15 parts by weight per 100 parts by weight of polyethylene. If more than 15 parts by weight is added, all the pores between the porous silica are filled and breathability increases. This decreases, and if less than 5 parts by weight is added, the voids between the porous silica are insufficiently filled, thereby maximizing breathability, but there is a problem in that the bonding force is reduced. Therefore, it is preferable to have the limited weight part as described above.
탄산칼슘은, 코팅제의 두께를 확보하기 위한 것으로서, 인장강도를 확보하고 신장율 등의 기계적 특성이 저하되지 않도록 입도가 30㎛ 미만인 것이 좋으며, 폴리에틸렌 100중량부에 대하여 3~5중량부가 첨가되는데, 5중량부 보다 많이 첨가되면 다공성실리카와 탈크 사이의 공극이 모두 충전되어 통기성이 저하되고, 3중량부 보다 적게 첨가되면 코팅층 또는 방수층의 두께 확보가 어려워 인장강도가 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다.Calcium carbonate is used to secure the thickness of the coating, and it is recommended that the particle size be less than 30㎛ to ensure tensile strength and not deteriorate mechanical properties such as elongation, and is added in an amount of 3 to 5 parts by weight per 100 parts by weight of polyethylene. If more than 3 parts by weight is added, all the pores between the porous silica and talc are filled, reducing breathability, and if less than 3 parts by weight is added, it is difficult to secure the thickness of the coating layer or waterproof layer, which reduces the tensile strength. It is preferable to have parts by weight.
한편, 본 발명의 바람직한 실시예에 따른 통기성 코팅제가 코팅된 복합방수용 보강재는, 100~150g/m2의 면밀도를 가지고 통기성 코팅제가 한쪽면에 코팅된 부직포를 포함한다.Meanwhile, the composite waterproofing reinforcement material coated with a breathable coating according to a preferred embodiment of the present invention has an area density of 100 to 150 g/m 2 and includes a nonwoven fabric coated on one side with a breathable coating.
여기서, 통기성 코팅제는, 보다 바람직하게는, 폴리에틸렌 100중량부에 폴리프로필렌 70~90중량부, 하이드록시아세틱에시드 60~80중량부, 벤질브로마이드 50~70중량부, 카복실릭에시드 40~60중량부, 메틸마그네슘아이오다이드 30~50중량부 및 폴리에틸렌테레프탈레이트 20~40중량부가 첨가되고 250℃~300℃에서 3~5시간 용융된 후 다공성실리카 10~30중량부, 탈크 5~15중량부 및 탄산칼슘 3~5중량부가 혼합되는 것을 통해 제조된다.Here, the breathable coating agent is more preferably 70 to 90 parts by weight of polypropylene, 60 to 80 parts by weight of hydroxyacetic acid, 50 to 70 parts by weight of benzyl bromide, and 40 to 60 parts by weight of carboxylic acid per 100 parts by weight of polyethylene. 30 to 50 parts by weight of methyl magnesium iodide and 20 to 40 parts by weight of polyethylene terephthalate are added and melted at 250°C to 300°C for 3 to 5 hours, followed by 10 to 30 parts by weight of porous silica and 5 to 15 parts by weight of talc. and 3 to 5 parts by weight of calcium carbonate.
또한, 부직포의 경우 100~150g/m2의 면밀도를 가지는데, 면밀도가 150g/m2를 초과하게 되면 상기 코팅제의 코팅시 부직포 내부를 향해 코팅제가 일정 깊이로 침투되지 못하는 낮은 투과율을 가지게 되어 구조물의 바닥면과의 이격 현상이 발생되고 방수층이 분리 및 균열되어 오히려 인장 강도와 전단 강도가 저하되고, 면밀도가 100g/m2에 미만하게 되면 상기 코팅제의 코팅시 부직포 내부를 향해 코팅제가 모두 침투되는 높은 투과율을 가지게 되어 부직포의 일면에 코팅제를 통한 방수층이 형성되지 못하여 인장 강도와 전단 강도 및 방수성이 저하되는 문제점이 있으므로, 상기와 같은 면밀도를 가지는 것이 바람직하다.In addition, non-woven fabric has an areal density of 100 to 150 g/m 2. If the areal density exceeds 150 g/m 2 , the coating agent has a low transmittance that prevents the coating agent from penetrating to a certain depth into the inside of the non-woven fabric, thereby damaging the structure. Separation from the bottom surface occurs, the waterproof layer separates and cracks, and the tensile strength and shear strength decrease, and when the area density is less than 100 g/m 2 , the coating agent penetrates into the inside of the nonwoven fabric when the coating agent is coated. Due to the high transmittance, there is a problem in that a waterproof layer through the coating agent cannot be formed on one side of the nonwoven fabric, which reduces the tensile strength, shear strength, and waterproofness, so it is desirable to have the above-mentioned areal density.

이후, 상기와 같이 제조된 통기성 코팅제가 코팅된 복합방수용 통기성 보강재와 시제품을 600mm*600mm*50mm의 콘크리트 시험체에 시공하여 상부 바탕면까지 침적시킨 후, 80℃에서 168시간이 지난 후 수증기압에 의한 부풀음 유무를 관찰한 후 그 결과를 표 1에 나타내었으며, 실시예 2에서는 바탕면에서 발생하는 수증기를 효과적으로 배출시켜 수증기압에 의한 부풀음이 발생하지 않았고, 실시예 1과 실시예 3에서는 전체 면적 중 일부분에만 부풀음이 발생하였으며, 시제품에는 전체 면적이 전부 부품음이 발생하였다.Afterwards, the breathable reinforcing material for composite waterproofing and the prototype coated with the breathable coating prepared as described above were installed on a concrete test specimen of 600mm*600mm*50mm and immersed up to the upper surface, and then swelled due to water vapor pressure after 168 hours at 80°C. After observing the presence or absence, the results are shown in Table 1. In Example 2, water vapor generated from the base surface was effectively discharged, so swelling due to water vapor pressure did not occur, and in Examples 1 and 3, only a portion of the total area was observed. Swelling occurred, and parts noise occurred throughout the entire area of the prototype.
따라서 본 발명에 의하면, 폴리에틸렌에 폴리프로필렌, 하이드록시아세틱에시드, 벤질브로마이드, 카복실릭에시드, 메틸마그네슘아이오다이드 및 폴리에틸렌테레프탈레이트를 용융시킨 후 다공성실리카, 탈크 및 탄산칼슘을 혼합하여 통기성 코팅제를 제조하고 소정 두께의 부직포 한쪽면에 코팅한 복합방수용 통기성 보강재를 통하여 구조물의 바닥면에 부착되고 도막방수재의 도포 시공후 부풀음을 방지하여 복합방수공법의 완성도를 향상시킬 수 있다.Therefore, according to the present invention, polypropylene, hydroxyacetic acid, benzyl bromide, carboxylic acid, methylmagnesium iodide, and polyethylene terephthalate are melted in polyethylene, and then porous silica, talc, and calcium carbonate are mixed to create a breathable coating agent. Through the breathable reinforcing material for composite waterproofing manufactured and coated on one side of the non-woven fabric of a certain thickness, it is attached to the bottom of the structure and prevents swelling after application of the coating waterproofing material, thereby improving the completeness of the composite waterproofing method.
