Description
본 발명은 메쉬 함침형 다중방수시트에 관한 것으로서, 더욱 상세하게는 PVC시트를 열풍을 통해 가열한 후 일면에는 메쉬층을 함침시키고 타면에는 부직포가 접착되도록 하여 방수 시공시 수밀성과 내균열성을 향상시켜 우수한 방근 효과를 얻을 수 있는 메쉬 함침형 다중방수시트에 관한 것이다. The present invention relates to a mesh-impregnated multi-waterproof sheet, and more particularly, after heating a PVC sheet through hot air, a mesh layer is impregnated on one side and a nonwoven fabric is adhered to the other side to improve water tightness and crack resistance during waterproof construction. It relates to a mesh-impregnated multi-waterproof sheet capable of obtaining an excellent anti-dust effect.
일반적으로, 건축구조물의 옥상이나 지하기초바닥 및 지하외벽, 지하주차장 상부슬라브 방수와 토목구조물로서 지하철ㆍ지하차도ㆍ전력구ㆍ통신구 등의 공동구와 같은 지하 콘크리트 구조물의 방수에 적용되는 방수공법은 대표적으로 시트방수와 도막방수 및 복합방수로 분류할 수 있다.In general, the waterproofing method applied to the waterproofing of underground concrete structures such as the roof of the building structure, the subterranean subfloor and the outer wall of the basement, the upper slab of the underground parking lot, and the civil engineering structure, such as public areas such as subways, underground roadways, power outlets, communication zones, etc. Representatively, it can be classified into sheet waterproofing, coating waterproofing, and composite waterproofing.
시트방수는 아스팔트 시트 방수층이 콘크리트 바탕면과의 접착력 부족에 의한 방수층의 들뜸현상 발생과, 방수시트 연결이음부위에 토우치(Torch)를 사용하여 가열 용융접합시 아스팔트 콤파운드의 연소, 산화에 의한 방수시트 연결이음부위 수밀성이 약화되어 이음부에서의 누수사고가 빈번하게 발생되는 문제점이 있다.The waterproofing of the sheet is that the waterproofing of the waterproofing layer occurs due to the lack of adhesion to the concrete base surface of the asphalt sheet, and the waterproofing by combustion and oxidation of the asphalt compound during heat-melt bonding by using a torch at the connection joint of the waterproofing sheet. There is a problem in that the watertightness of the seat connection joint is weakened, causing frequent leaks in the joint.
즉, 방수시트의 제조시 다양한 적층구조를 통해서 필요한 물성을 구현하기가 쉽고, 균일한 두께와 품질 확보가 용이하며, 시공이 간편한 장점이 있는 반면에, 시트방수는 복잡한 부위의 시공이 어렵고, 부분 보수가 어려우며, 시트 단부 및 코너 처리가 곤란하고, 시트간 접합부(조인트)에서의 수밀성이 취약하여 완전 수밀성을 이루기 어렵다는 것이다.In other words, when manufacturing a waterproof sheet, it is easy to implement the necessary physical properties through a variety of lamination structures, it is easy to secure uniform thickness and quality, and there are advantages of easy construction, whereas the sheet waterproofing is difficult to construct in complex areas and Repair is difficult, sheet end and corner treatment is difficult, and watertightness at joints (joints) between sheets is poor, making it difficult to achieve complete watertightness.
도막방수는 소재에 따라 다르지만, 대표적으로, 우레탄계 도막방수와 고무아스팔트계 도막방수 등을 로울러나 붓을 사용하여 간편하여 도포하는 방법으로, 시공성 및 방수층의 신장력이 우수하여 콘크리트 구조체의 미세균열에도 대응할 수 있는 장점이있으나, 도막방수재를 수차례 도포해야 하기 때문에 도막 방수층의 균등한 두께를 형성하는데 어려움이 있으며, 방수층의 부분적인 기포나 꽈리 등의 발생에 의해 방수층 결함부위가 빈번하게 발생되는 단점이 있다.Coating waterproofing differs depending on the material, but typically, it is a simple method of applying urethane-based coating waterproofing and rubber asphalt-based coating waterproofing using a roller or brush. It has excellent workability and elongation of the waterproofing layer, so it can respond to microcracks of concrete structures. It has the advantage of being able to, but it is difficult to form the even thickness of the coating waterproofing layer because the coating waterproofing material has to be applied several times, and the defects of the waterproofing layer frequently occur due to the occurrence of partial air bubbles or cracks in the waterproofing layer. have.
또한, 도막방수는, 콘크리트면 등의 하지면에 밀착되는 밀착 공법이므로, 균열 대응력에 취약하여 하지의 균열에 대한 근본적인 해결이 어렵고, 균열 발생시 시공된 우레탄 도막이 손상되며, 연속적으로 들뜨게 되는 단점이있고, 바탕의 평활도 및 건조상태에 영향을 크게 받는데, 작업현상에서 액상으로 도포되어 흐름성이 좋기 때문에, 바닥면의 굴곡으로 인해 도막 두께가 불균일해질 수 있고, 도막의 두께를 충분히 형성하여야 하나 현장 시공상 용이하지가 않은 단점이 있다.In addition, since the coating waterproofing is a close contact method that adheres to the base surface such as a concrete surface, it is difficult to fundamentally solve the crack of the base due to its weak crack response ability, and when a crack occurs, the constructed urethane coating film is damaged, and there is a disadvantage that it is continuously lifted. , It is greatly affected by the smoothness and dry condition of the base.Since it is applied as a liquid in the working phenomenon and has good flowability, the thickness of the coating film may be uneven due to the curvature of the bottom surface, and the thickness of the coating film must be sufficiently formed, but on-site construction There is a disadvantage that it is not easy.
한편, 상기한 시트방수와 도막방수의 단점을 서로 보완하하기 위한 시트방수와 도막방수의 복합구조인 복합방수는, 고분자계 또는 아스팔트 방수시트와 열공법 또는 냉공법에 의해 도포되는 도막방수재의 조합이 가장 일반적이다.On the other hand, the composite waterproofing, which is a composite structure of sheet waterproofing and coating waterproofing to compensate for the disadvantages of the above-described sheet waterproofing and coating waterproofing, is a combination of a polymeric or asphalt waterproofing sheet and a coating waterproofing material applied by a heat method or a cooling method. This is the most common.
그러나, 상기한 복합방수는 도막방수의 재료로서 용제형 또는 수용성 아스팔트 도막방수재가 일반적으로 사용되는데, 이는 도막 두께확보를 위해 수회에 걸쳐 도포 작업을 하여야 하므로, 양생시간, 시공기간이 길어지고 이에 따라 시공비용이 과도하게 소요되며, 도막방수재가 양생되고 난 후 비로소 방수시트를 부착하는 작업이 가능하므로, 시공기간 및 시공비용의 증가가 더욱 부각되며, 열공법(도막방수재의 양생을 위해 가열이 필요한 공법)을 적용하는 경우, 화재의 위험과 유해물질의 발생 등의 문제점이 있었다.However, the above-described composite waterproofing is generally a solvent-type or water-soluble asphalt coating waterproofing material as a material for coating film waterproofing, which requires coating work several times to secure the coating thickness, so the curing time and construction period are lengthened. The construction cost is excessive, and since it is possible to attach the waterproof sheet only after the coating waterproofing material is cured, the increase in the construction period and construction cost is more prominent, and the thermal method (heating is necessary for curing the coating waterproofing material. In the case of applying the construction method), there were problems such as the risk of fire and generation of hazardous substances.

It is to provide a mesh-impregnated multi-waterproof sheet that can be obtained.
본 발명에 의하면, PVC시트와; PVC시트의 일면에 함침 구성되는 메쉬층과; PVC시트의 타면에 접합 구성되는 부직포층을 포함하고, 상기 PVC시트는, 부직포층의 부직포 100 중량부에 대하여, 콤파운드 700 내지 750 중량부, 디옥틸프탈레이트 50 내지 70 중량부, 아라크라 200 내지 220 중량부, 프로필렌글리콜 20 내지 40 중량부 및 안료 10 내지 20 중량부를 포함하는 메쉬 함침형 다중방수시트가 제공된다.According to the present invention, a PVC sheet; A mesh layer impregnated on one side of the PVC sheet; It includes a non-woven fabric layer bonded to the other side of the PVC sheet, and the PVC sheet includes 700 to 750 parts by weight of compound, 50 to 70 parts by weight of dioctyl phthalate, 200 to 220 of Arachra based on 100 parts by weight of the non-woven fabric of the non-woven fabric layer. A mesh-impregnated multi-waterproof sheet comprising 20 to 40 parts by weight of propylene glycol and 10 to 20 parts by weight of pigment is provided.
여기서, 메쉬층은, 0.1mm ~ 1.0mm의 간격의 메쉬 크기를 가지고, 유리섬유와 합성수지가 7:3 또는 5:5 중량비율 중 어느 하나를 가지는 것이 바람직하다.Here, it is preferable that the mesh layer has a mesh size of 0.1mm to 1.0mm, and the glass fiber and the synthetic resin have any one of 7:3 or 5:5 weight ratio.
본 발명에 의하면, PVC시트를 열풍을 통해 가열한 후 일면에는 메쉬층을 함침시키고 타면에는 부직포가 접착되도록 하여 방수 시공시 수밀성과 내균열성을 향상시켜 우수한 방근 효과를 얻을 수 있다. According to the present invention, after heating the PVC sheet through hot air, a mesh layer is impregnated on one side and a nonwoven fabric is adhered to the other side, thereby improving watertightness and crack resistance during waterproof construction, thereby obtaining an excellent anti-dust effect.
이하, 본 발명에 따른 메쉬 함침형 다중방수시트를 상세히 설명하면 다음과 같다.Hereinafter, the mesh-impregnated multi-waterproof sheet according to the present invention will be described in detail as follows.
본 발명에 따른 메쉬 함침형 다중방수시트는, PVC시트와, PVC시트의 일면에 함침 구성되는 메쉬층과, PVC시트의 타면에 접합 구성되는 부직포층을 포함한다.The mesh-impregnated multi-waterproof sheet according to the present invention includes a PVC sheet, a mesh layer impregnated on one surface of the PVC sheet, and a nonwoven fabric layer bonded to the other surface of the PVC sheet.
부직포층은, 상기와 같은 다중방수시트에 의해 방수 기능이 제공될 바탕면에 방수 시공을 위하여 도포되는 도막제나 접착제가 흡수 또는 합침되도록 하여 상기 다중방수시트가 바탕면에 부착된 상태를 가지도록 하는 수단으로서, 폴리에스테르 얀 등의 재질을 가지는 것이 바람직하다.The non-woven fabric layer absorbs or impregnates the coating agent or adhesive applied for waterproof construction on the base surface to be provided with a waterproof function by the multi-waterproof sheet as described above, so that the multi-waterproof sheet has a state attached to the base surface. As a means, it is preferable to have a material such as polyester yarn.
여기서, 상기 부직포층은, 바탕면에 시공되는 도막제나 접착제의 흡수나 함침이 보다 용이하도록 다수개의 흡착홈이 구성될 수 있다.Here, the nonwoven fabric layer may have a plurality of adsorption grooves to facilitate absorption or impregnation of the coating agent or adhesive applied to the base surface.
메쉬층은, 부직포층에 상면에 위치된 상태에서 방수층의 도포 또는 함침시 부직포층에 구성되어 내구성을 제공하기 위한 수단으로서, 유리섬유나 유리섬유와 합성수지의 혼합으로 이루어지고, 0.1mm ~ 1.0mm의 간격의 메쉬 크기를 가지는 것이 좋다.The mesh layer is a means for providing durability by being configured on the nonwoven layer when applying or impregnating the waterproof layer while being positioned on the upper surface of the nonwoven layer, and is made of glass fiber or a mixture of glass fiber and synthetic resin, and is 0.1mm to 1.0mm It is good to have a mesh size of spacing of.
한편, 상기 메쉬층은, 유리섬유와 합성수지가 혼합되는 경우에는 7:3 또는 5:5 중량비율 중 어느 하나로 구비됨이 바람직하다.On the other hand, the mesh layer is preferably provided in any one of 7:3 or 5:5 weight ratio when the glass fiber and synthetic resin are mixed.
따라서 메쉬층이 PVC시트의 일면에 함침 구성됨에 따라 내균열성이 향상되고 방근 효과도 향상될 수 있다. Therefore, as the mesh layer is impregnated on one side of the PVC sheet, the crack resistance is improved and the anti-dust effect can be improved.
PVC시트는, 일면에는 메쉬층이 함침 구성되고 타면에는 부직포층이 접합 구성되어 방수 기능을 제공하는 것으로서, 소정의 온도를 가지는 열풍에 의해 용융된 후 상기 메쉬층과 부직포층이 용착되도록 하기 위하여, 콤파운드(재생PVC), 디옥틸프탈레이트(LGflex GL300), 아라크라(S1000), 프로필렌글리콜(PBP-10F) 및 안료(AT BLACK 230) 등을 포함한다.The PVC sheet is configured to impregnate a mesh layer on one side and a nonwoven fabric layer on the other side to provide a waterproof function, and to allow the mesh layer and the nonwoven fabric layer to be welded after being melted by hot air having a predetermined temperature, Compound (regenerated PVC), dioctylphthalate (LGflex GL300), Arachra (S1000), propylene glycol (PBP-10F), and pigment (AT BLACK 230).
상기 PVC시트는, 구체적으로는, 부직포층의 부직포 100 중량부에 대하여, 콤파운드 700 내지 750 중량부, 디옥틸프탈레이트 50 내지 70 중량부, 아라크라 200 내지 220 중량부, 프로필렌글리콜 20 내지 40 중량부 및 안료 10 내지 20 중량부를 포함한다.The PVC sheet, specifically, based on 100 parts by weight of the non-woven fabric of the non-woven fabric layer, 700 to 750 parts by weight of the compound, 50 to 70 parts by weight of dioctylphthalate, 200 to 220 parts by weight of Arakra, 20 to 40 parts by weight of propylene glycol And 10 to 20 parts by weight of a pigment.
여기서, 상기 PVC시트와 부직포층은, 보다 바람직하게는, 부직포 8.8 중량%, 콤파운드 63.5 중량%, 디옥틸프탈레이트 5 중량%, 아라크라 19 중량%, 프로필렌글리콜 2.5 중량% 및 안료 1.2 중량%를 포함하는 것이 좋다.Here, the PVC sheet and the non-woven layer, more preferably, non-woven 8.8% by weight, compound 63.5% by weight, dioctylphthalate 5% by weight, Arachra 19% by weight, propylene glycol 2.5% by weight and 1.2% by weight of the pigment included It is good to do.
콤파운드는, 열에 강하고 마찰계수가 극히 낮으며 좋은 내화학성 특징을 통하여 부식을 방지하고 코팅 기능을 통하여 부직포의 내구성을 향상시키고 방수 및 방근 기능이 극대화되도록 하기 위한 것으로서, PVC 수지, 나이트로아세틱에시드 및 에틸아크릴레이트가 3:0.5:0.5의 부피비로 혼합된다.The compound is resistant to heat, has an extremely low coefficient of friction, and is designed to prevent corrosion through good chemical resistance characteristics, improve the durability of non-woven fabrics through a coating function, and maximize waterproof and anti-dust functions.PVC resin, nitroacetic acid And ethyl acrylate are mixed in a volume ratio of 3:0.5:0.5.
이때, PVC 수지는, 점도 유지 등을 제공하는 것이면, 공지의 조성물이어도 무방하다. At this time, the PVC resin may be a known composition as long as it provides viscosity maintenance and the like.
여기서, PVC 수지는 적절한 점도 유지와 부직포의 피막강도, 인장강도 및 내후성을 적절히 유지시키고, 나이트로아세틱에시드는 접착강도를 향상시키며, 에틸아크릴레이트는 혼합물들의 점도를 조절하는 기능을 제공하기 위한 것으로서, 상기 PVC 수지가 3 부피비를 초과하는 경우에는 상기 PVC시트 조성물들의 반응속도가 너무 빨라지게 되어 교반성 및 시공성이 저하되고 3 부피비를 미만하는 경우에는 상기 PVC시트 조성물들의 반응속도가 너무 느려지게 되어 제조 시간이 증가하게 되며, 상기 나이트로아세틱에시드가 0.5 부피비를 초과하는 경우에는 접착 강도가 너무 커지게 되어 상기 PVC시트 조성물들의 교반성이 저하되고 0.5 부피비를 미만하는 경우에는 조성물들의 접착 강도가 저하되며, 상기 에틸아크릴레이트가 0.5 부피비를 초과하는 경우에는 물성 효과가 저하되어 상기 PVC시트 조성물들의 끈적거림이 심하게 발생되고 0.5 부피비를 미만하는 경우에는 점도 안정성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 부피비를 가지는 것이 좋다.Here, the PVC resin maintains an appropriate viscosity and adequately maintains the film strength, tensile strength and weather resistance of the nonwoven fabric, nitroacetic acid improves the adhesive strength, and ethyl acrylate provides a function to control the viscosity of the mixtures. As a result, when the PVC resin exceeds 3 volume ratio, the reaction speed of the PVC sheet compositions becomes too fast, so that agitation and workability decrease, and when it is less than 3 volume ratio, the reaction speed of the PVC sheet compositions becomes too slow. As a result, the manufacturing time increases, and when the nitroacetic acid exceeds 0.5 volume ratio, the adhesive strength becomes too large, so that the agitation properties of the PVC sheet compositions decrease, and when it is less than 0.5 volume ratio, the adhesive strength of the compositions Is lowered, and when the ethyl acrylate exceeds 0.5 volume ratio, the physical property effect decreases, resulting in severe stickiness of the PVC sheet compositions, and when it is less than 0.5 volume ratio, there is a problem in that viscosity stability is lowered. It is better to have the same limited volume ratio.
한편, 본 발명에 있어서, 상기 컴파운드는, 부직포층의 부직포 100 중량부에 대하여 700 내지 750 중량부가 첨가되는데, 750 중량부를 초과하는 경우에는 부직포의 밀도 보다 많은 양이 도포되어 방수 성능은 좋아지지만 부직포의 하면 즉, 바탕면에 접촉되어야 할 부분까지 함침이 진행되어 바탕면 또는 도막제나 접착제와의 접착력이 저하되고, 700 중량부에 미만하는 경우에는 부직포의 밀도 보다 적은 양이 도포되어 방수 성능도 저하되고 부직포의 하면 가까이 침투되지 못하여 상기 도막제나 접착제에 의한 접착층과 분리된 상태를 가지게 되어 부직포가 바탕면으로부터 쉽게 떨어지게 되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Meanwhile, in the present invention, the compound is added in an amount of 700 to 750 parts by weight based on 100 parts by weight of the non-woven fabric of the non-woven fabric layer, and if it exceeds 750 parts by weight, a larger amount than the density of the non-woven fabric is applied to improve waterproof performance, but the non-woven fabric The lower surface of the fabric, that is, the part that needs to be in contact with the base surface, is impregnated, and the adhesion with the base surface or the coating agent or adhesive decreases, and if it is less than 700 parts by weight, less than the density of the non-woven fabric is applied and the waterproof performance is also reduced Since the nonwoven fabric cannot penetrate close to the lower surface of the nonwoven fabric, it is separated from the adhesive layer by the coating agent or the adhesive, so that the nonwoven fabric is easily separated from the base surface. Therefore, it is preferable to have a limited weight as described above.
디옥틸프탈레이트는, 가소 기능을 제공하여 PVC시트 또는 다중방수시트의 내열성과 내주름성 등을 향상시키기 위한 것으로서, 부직포층의 부직포 100 중량부에 대하여 50 내지 70 중량부가 첨가되는데, 70 중량부를 초과하는 경우에는 부직포의 인장강도가 오히려 저하되고, 50 중량부에 미만하는 경우에는 가소 기능이 저하되어 경화시간의 지연 및 접착력이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Dioctylphthalate is to improve the heat resistance and wrinkle resistance of the PVC sheet or multi-waterproof sheet by providing a plasticizing function, and 50 to 70 parts by weight is added based on 100 parts by weight of the nonwoven fabric of the nonwoven fabric layer, exceeding 70 parts by weight. In this case, the tensile strength of the nonwoven fabric is rather lowered, and if it is less than 50 parts by weight, the plasticizing function is deteriorated, thereby delaying the curing time and lowering the adhesive strength. Therefore, it is preferable to have the above limited parts by weight.
아라크라는, 부직포층이 PVC시트에 용착 접합시 신장률을 제공하여 작업성을 향상시키고 인장강도와 내열성을 향상시키기 위한 것으로서, 부직포층의 부직포 100 중량부에 대하여 200 내지 220 중량부가 첨가되는데, 220 중량부를 초과하는 경우에는 PVC시트의 신장률이 너무 커지게 되어 인장강도가 오히려 저하되어 방근 성능이 저하되고, 200 중량부에 미만하는 경우에는 PVC시트의 신장률이 작아지게 되어 작업성 및 내주름성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Arachra is intended to improve workability and improve tensile strength and heat resistance by providing elongation when the nonwoven fabric layer is welded and bonded to the PVC sheet, and 200 to 220 parts by weight is added to 100 parts by weight of the nonwoven fabric of the nonwoven fabric layer. If it exceeds part, the elongation rate of the PVC sheet becomes too large, and the tensile strength is rather deteriorated, and the anti-rotation performance decreases. If it is less than 200 parts by weight, the elongation rate of the PVC sheet decreases, resulting in a decrease in workability and wrinkle resistance. Since there is a problem, it is good to have a limited weight part as described above.
프로필렌글리콜은, 부직포층이 PVC시트에 용착 접합시 PVC시트의 접착 강도를 향상시키기 위한 것으로서, 요소가가 2.0 이하, 검화가가 190-200인 경우 접착 강도가 매우 우수하게 되므로 이런 특성을 가지는 것이 좋으며, 부직포층의 부직포 100 중량부에 대하여 20 내지 40 중량부가 첨가되는데, 40 중량부를 초과하는 경우에는 점도가 커지게 되어 부직포의 하면 깊숙이 침투되지 못하게 되어 내구성이 저하되고 20 중량부에 미만하는 경우에는 저장 안정성이 저하되어 부직포의 도포 작업성이 오히려 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Propylene glycol is intended to improve the adhesive strength of the PVC sheet when the non-woven fabric layer is welded to the PVC sheet.If the urea value is 2.0 or less and the saponification value is 190-200, the adhesive strength is very good, so it is good to have these characteristics. , 20 to 40 parts by weight are added based on 100 parts by weight of the non-woven fabric of the non-woven fabric layer.If it exceeds 40 parts by weight, the viscosity increases and the non-woven fabric cannot penetrate deep into the lower surface of the non-woven fabric. Since storage stability is deteriorated, the coating workability of the nonwoven fabric is rather deteriorated, so it is preferable to have a limited weight part as described above.
안료는, PVC시트가 소정의 색깔을 가지도록 하기 위한 것으로서, 부직포층의 부직포 100 중량부에 대하여 10 내지 20 중량부가 첨가되는데, 상기 범위를 벗어나는 경우에는 다중방수시트 또는 PVC시트 색상의 심미감이 저하되므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.The pigment is to make the PVC sheet have a predetermined color, and 10 to 20 parts by weight is added based on 100 parts by weight of the non-woven fabric of the non-woven fabric layer. If it is out of the above range, the aesthetic feeling of the color of the multi-waterproof sheet or the PVC sheet is Since it is lowered, it is good to have a limited weight part as described above.
