Abstract
Description
제1도는 본 발명에 따른 방수 시이트의 제조공정을 나타내는 순서도이다.1 is a flowchart showing a manufacturing process of the waterproof sheet according to the present invention.
본 발명은 방수특성이 우수한 방수 시이트 조성물에 관한 것이다.The present invention relates to a waterproof sheet composition having excellent waterproof properties.
일반적으로 인공호수나 정원 쓰레기매립장, 지하터널을 만들때 누수 또는 지하 개스 누추을 방지하기 위해 콘크리트를 두껍게 타설해 주었는바, 이러한 콘크리트를 타설하기 위해서는 공사비가 많이 소요될 뿐만 아니라 부식등에 의해 내구성이 저하되는 문제점이 있다.In general, when making artificial lakes, garden landfills and underground tunnels, concrete was thickly placed to prevent leakage or leaking of underground gas.In addition, the construction costs are high and the durability is degraded due to corrosion. There is this.
이러한 문제점을 해결하기 위해 종래에도 PVC로 제조된 방수 시이트를 시공하여 방수처리가 행하여지도록 하고 있는데, 이러한 PVC제의 방수 시이트는 가소제 및 각종 첨가제를 이용하여 유연성을 크게 할 수 있는 이점은 있으나 오히려 상기 첨가물의 표면침출에 의해 재질이 변화되어 방수성 및 가공성이 저하될 뿐만 아니라 광폭의 시이트를 제조하기 어렵다는 결점이 있다.In order to solve this problem, the waterproof sheet made of PVC is conventionally waterproofed to be performed. Such a waterproof sheet made of PVC has an advantage of increasing flexibility by using a plasticizer and various additives, but rather, Due to the surface leaching of the additives, the material is changed and the water resistance and the workability are lowered, and there is a drawback that it is difficult to manufacture a wide sheet.
이를 위해 폴리에틸렌제의 방수 시이트도 제안되고 있으나, 이와같은 종래 폴리에틸렌제의 방수 시이트는 단일물질, 예컨대 HDPE(High-Density Poly-Ethylene)이나 LDPE(Low-Density Poly Ethylene)등으로 이루어지는바, 이러한 단일물질은 유연성이 걸여되어 취급하기가 용이하지 않게 되어 시공성이 저하되는 결점이 있다.For this purpose, a polyethylene waterproof sheet is also proposed, but such a conventional polyethylene waterproof sheet is made of a single material such as HDPE (High-Density Poly-Ethylene) or LDPE (Low-Density Poly Ethylene). The material has the disadvantage of being flexible and not easy to handle, resulting in poor workability.
이에 본 발명은 상기와 같은 종래 기술의 결점을 해결하기 위해 발명된 것으로 방수 특성이 기존의 방수 재료보다 우수할 뿐만 아니라 유연성을 부여하여 시공성을 향상시킨 방수 시이트 조성물을 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the drawbacks of the prior art as described above, and its object is to provide a waterproof sheet composition which is not only superior to conventional waterproof materials but also provides flexibility to improve workability.
상기와 같은 목적을 달성하기 위한 본 발명은, LLDPE가 55∼90중량%, EVA가 5∼27.9중량%, 바이투멘(Bitumen)이 5∼15중량%, 산화방지제가 0.1∼0.3중량% 및 카본블랙 2∼3중량%를 반바리 믹서(Banbury mixer)에서 충분히 혼합한 후 압출기로 압출하여 펠렛으로 형성한 다음, 이 펠렛을 다시 T형다이에서 시이트상으로 압출시키면서 한쪽면 또는 양쪽면을 엠보싱 처리하여 이를 감아줌으로써 제조가 완료 되는바, 이렇게 제조되는 방수 시이트는 그 투습도가 10-10g/s.m.Pa 이하가 되어 방수성이 증대되는 것이다.The present invention for achieving the above object is 55 to 90% by weight of LLDPE, 5 to 27.9% by weight of EVA, 5 to 15% by weight of Bitumen, 0.1 to 0.3% by weight of antioxidant and carbon 2 to 3 wt% of black is sufficiently mixed in a Banbury mixer, extruded into an extruder to form pellets, and then embossed on one or both sides while the pellet is extruded again from a T-die. The manufacturing is completed by winding it up, the waterproof sheet is manufactured so that the moisture permeability is less than 10 -10 g / smPa is to increase the waterproof.
이하, 본 발명의 실시예를 설명한다.Hereinafter, embodiments of the present invention will be described.
[제1실시예][First Embodiment]
본 실시예에서는 LLDPE 55중량%와, EVA가 27.9중량%, 바이투멘이 15중량%, 산화방지제 0.1중량% 및, 카본블랙이 2중량%인 조성물을 제1도에 도시한 바와같이 반바리믹서에서 120∼140℃로 가열하면서 15∼20분가량 충분히 혼합한 다음, 이를 압출기에서 160∼170℃ 정도로 가열하면서 압출하여 펠릿으로 성형하고, 다시 이 펠릿을 T형 다이에서 160∼170℃ 정도로 가열하면서 시이트상으로 압출시키며, 이렇게 압축된 시이트의 한쪽면 또는 양쪽면에는 엠보싱 처리를 하여 소정의 길이로 권회하면 방수 시이트의 제조가 완료된다.In this embodiment, the composition of 55% by weight of LLDPE, 27.9% by weight of EVA, 15% by weight of bitumen, 0.1% by weight of antioxidant, and 2% by weight of carbon black is shown in Fig. 1. 15 to 20 minutes is sufficiently mixed while heating to 120-140 ° C. at 150 ° C., then extruded while heating to 160-170 ° C. in an extruder, and formed into pellets. The sheet is extruded into a sheet, and one side or both sides of the sheet thus compressed are embossed to be wound in a predetermined length to complete the production of the waterproof sheet.

이상과 같은 조성비로 이루어지는 본 발명에 의한 방수 시이트는 다음 도표에서 비교되는 바와같이 기존의 단일물질로 이루어진 HDPE제의 방수시이트보다 투수성이 낮아 방수특성이 낮아 방수특성이 향상됨을 알 수 있고, 또 제1실시예가 제2, 제3실시예보다 접합성 및 유연성이 양호함을 알 수 있다.The waterproof sheet according to the present invention having the above composition ratio has a low water permeability than the waterproof sheet made of HDPE, which is made of a single material, as compared with the following chart. It can be seen that the first embodiment has better bonding and flexibility than the second and third embodiments.
이상과 같이 설명된 본 발명에 의하면, LLDPE, EVA, 바이투멘, 산화방지제 및 카본블랙을 본 발명에 따라 소정비율로 배합하여 제조된 방수 시이트는 투습도가 낮아 방수성이 우수할 뿐만 아니라 접합성 및 유연성이 양호하며 방수 시이트의 시공시 취급이 용이하게 되어 시공작업이 현저히 단축되는 등의 탁월한 효과를 갖는다.According to the present invention described above, the waterproof sheet prepared by combining LLDPE, EVA, bitumen, antioxidant and carbon black in a predetermined ratio according to the present invention is not only excellent in waterproofness and low water vapor permeability but also excellent adhesion and flexibility. Good and easy handling during construction of the waterproof sheet has an excellent effect, such as significantly shortening the construction work.
