Description
본 발명은 부직포시트에 관한 것으로, 특히, 얇게 제조되어도 인열강도, 인장강도가 향상되며, 흡수성이 우수하여 도막방수재 또는 고점도 방수재 또는 컴파운드가 완벽하게 흡수, 함침시킬 수 있으므로, 우레탄 도막방수재 등과의 일체성이 우수하며, 아울러, 상, 하부 부직포 사이에 매쉬망을 삽입한 상태에서 고압으로 합지시킴으로써, 자체적인 주름발생을 방지하여 시공성이 우수하고, 상, 하부 부직포와 일체화된 매쉬망에 의하여 인열강도, 인장강도가 향상되는 부직포시트에 관한 것이다.The present invention relates to a nonwoven fabric sheet, and more particularly, it relates to a nonwoven fabric sheet which can be completely absorbed and impregnated with a coating film waterproofing material or a high viscosity waterproofing material or a compound because of its excellent tear strength and tensile strength, And the upper and lower nonwoven fabrics are laminated at a high pressure in a state where the mesh nets are inserted between the upper and lower nonwoven fabrics. A tear strength, and a tensile strength of the nonwoven fabric sheet.
근래 산업발전과 인구증가로 인해 주택, 아파트, 공장 등의 수많은 건축물이 증가 되었고, 그 구조에 있어서는 철근 콘크리트가 대표적이다. 일반적으로, 콘크리트는 경화하여 건조되고 수축하는 성질이 있으며, 수축되는 과정에서 균열이 발생하게 되고 균열의 내부로 수분이 쉽게 스며들게 되어 부식되거나 균열이 커지는 등의 결함이 발생하게 된다. In recent years, the number of buildings such as houses, apartments, and factories has increased due to industrial development and population increase, and reinforced concrete is a typical structure. Generally, concrete has a property of curing, drying and shrinking, and cracks are generated in the process of shrinkage, and moisture easily penetrates into cracks, resulting in defects such as corrosion or cracks.
이를 방지하고자 방수시트 또는 방수도막재 등의 방수재와 부직포를 사용하여 방수시공을 하게 된다.To prevent this, a waterproofing material such as a waterproof sheet or a waterproof coating material and a nonwoven fabric are used for waterproofing.
보통 부직포는 균열 및 부식이 일어난 구조물에 부착되어 방수 코팅되는 방식으로 시공되는데, 상세하게는, 도포된 방수액이 부직포의 내부로 흡수되며 방수층의 생성을 유도하여 방수 코팅하는 공법으로 사용된다.In general, the nonwoven fabric is applied in such a manner that the nonwoven fabric is adhered to a cracked and corroded structure to be waterproof coated. Specifically, the applied waterproofing liquid is absorbed into the nonwoven fabric and used as a waterproof coating by inducing the formation of a waterproof layer.
아울러, 방수시트의 중심기재로도 활용되는 바, 이때에도 방수재가 부직포에 함침됨으로써, 방수층이 생성되게 하는 목적으로 사용된다.In addition, it is used as a center base material of the waterproof sheet. At this time, the waterproof material is also impregnated into the nonwoven fabric so that a waterproof layer is formed.
하지만, 종래의 부직포는 섬유의 면을 곱게 하기 위해 열처리 과정을 거치고, 이 과정에서 섬유가 고밀도로 압축되어 흡수성이 저하되고 필터역할을 하게 된다. However, in the conventional nonwoven fabric, a heat treatment process is performed in order to increase the surface of the fiber, and in this process, the fibers are compressed with high density, so that the absorbency of the fiber is lowered and the filter functions.
이는 방수시공에 있어서 방수액을 도포시 부직포 내부로의 원활한 침투를 방해하고 도포 된 방수액이 부직포의 상부에서 머물게 되어, 방수층이 부직포의 외부로만 얇게 형성되어 내구성이 약하여 부직포와 방수층이 쉽게 분열하게 된다.This is because when the waterproofing solution is applied to the waterproofing solution, the waterproofing liquid hinders smooth penetration into the nonwoven fabric and the applied waterproofing liquid stays at the upper portion of the nonwoven fabric, and the waterproofing layer is formed only thinly outside the nonwoven fabric.
또한, 표면이 약해진 방수층은 외력에 의해 쉽게 파손되며, 이때 발생하는 균열로 인해 부직포 내부로 수분이 스며들게 되고, 부직포는 수분을 넓게 흡수하여 팽창되며 방수층의 균열을 유도하게 된다.In addition, the waterproof layer, whose surface is weakened, is easily broken by an external force, and moisture is imbedded into the nonwoven fabric due to cracks generated at this time, and the nonwoven fabric absorbs water widely to expand and induce cracks in the waterproof layer.
뿐만 아니라, 시공 시 부직포 자체적으로 형성된 주름으로 말미암아 이를 펼쳐가면서 작업을 해야 하므로 매우 번거롭다는 문제점이 있다.In addition, since the wrinkles formed on the nonwoven fabric itself are required to be spread while spreading, it is very troublesome.
본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로, 부직포의 인열강도, 인장강도를 증가시키되, 종래의 부직포보다 상대적으로 얇게 부직포가 제작될 수 있도록 하면서도 함침되는 방수재의 흡수성과 방수재와의 일체성이 증가되게 하며, 주름이 방지되게 하여 시공성이 향상될 수 있게 하는 부직포시트를 제공하는 데 그 목적이 있다.Disclosure of the Invention The present invention has been conceived to solve the problems described above. It is an object of the present invention to increase the tear strength and tensile strength of a nonwoven fabric, and to provide a nonwoven fabric which is relatively thinner than a conventional nonwoven fabric, And to provide a nonwoven fabric sheet which can improve the workability by preventing wrinkles from being formed.
상기한 목적은, 니들펀칭에 의해 제작되며, 액상의 접착바인더가 함침된 상, 하부 부직포(102)(104) 사이에 격자형 구조의 매쉬망(106)을 삽입한 후 850Kg ~ 1,000Kg으로 가압하는 가압롤러 사이를 통과시켜 합지된 것을 특징으로 하는 부직포시트(100)에 의해 달성된다.The above object is achieved by inserting a

본 발명에 따른 부직포시트는 흡수성이 우수하여 도막방수재 또는 고점도 방수재 또는 컴파운드가 완벽하게 흡수, 함침시킬 수 있으므로, 우레탄 도막방수재 등과의 일체성이 우수하며, 아울러, 상, 하부 부직포 사이에 매쉬망을 삽입한 상태에서 고압으로 합지시킴으로써, 자체적인 주름발생을 방지하여 시공성이 우수하고, 상, 하부 부직포와 일체화된 매쉬망에 의하여 인열강도, 인장강도가 향상되는 효과를 가진다.Since the nonwoven fabric sheet according to the present invention is excellent in absorbency and can be completely absorbed and impregnated with a coating film waterproofing material or a high viscosity waterproofing material or compound, it is excellent in integration with a urethane coating film waterproofing material and the like. Further, By joining them together at a high pressure in the state of being inserted, it is possible to prevent the occurrence of wrinkles themselves and to improve the workability, and the tear strength and the tensile strength are improved by the mesh net integrated with the upper and lower nonwoven fabrics.
뿐만 아니라, 상, 하부 부직포의 인장강도와 신율방향을 서로 반대방향으로 배열되게 함으로써, 인장강도나 신율이 어느 한 방향으로 편중되지 않게 함으로써, 균질한 방수시공 및 방수시트의 제작을 가능하게 하는 효과를 가진다.In addition, since the tensile strength and elongation direction of the upper and lower nonwoven fabrics are arranged in opposite directions to each other, the tensile strength and elongation are not biased in any one direction, thereby making it possible to produce a uniform waterproofing and waterproof sheet .
