Description

단열 및 인열성능이 보강된 PVC 방수시트{Polyvinyl chloride waterproof sheet}Polyvinyl chloride waterproof sheet with reinforced insulation and tear performance

본 발명은 단열 및 인열성능이 보강된 PVC 방수시트에 관한 것으로, 특히, PVC 시트의 단점인 노출에 의한 경화현상 및 이에 따른 크랙현상을 해결하여 내구성을 향상시키고, PVC 시트가 바탕면의 거동에 대하여 신축적이고 탄력적으로 순응하지 못하는 단점을 보완하여 인열강도를 향상시키면서 신축적이고 탄력적인 순응현상이 일어나도록 하며, 건물 외벽에 시공 시 단열효과가 향상될 수 있게 하는 단열 및 인열성능이 보강된 PVC 방수시트에 관한 것이다.The present invention relates to a PVC waterproof sheet reinforced with heat insulation and tearing performance, in particular, to improve the durability by solving the curing phenomenon and cracks caused by exposure, which is a disadvantage of the PVC sheet, and improves the durability of the PVC sheet surface surface PVC is reinforced with insulation and tearing performance to compensate for the weakness of elasticity and elasticity and to improve the tearing strength while improving the tearing strength and to improve the insulation effect when constructing the building's exterior wall. It relates to a waterproof sheet.

일반적으로 빌딩 구조물의 옥상이나 주차장의 상부면 등에는 강우 등으로 인한 누수를 방지하기 위해 방수 공사가 필수적이다. 이에는 여러 종류의 방수 공법이 사용되고 있으며, 주로 몰탈 액체방수, 수용성 또는 유용성의 도막 방수, 아스팔트 방수 및 방수시트 등이 사용되고 있다.In general, waterproof construction is essential on the roof of a building structure or an upper surface of a parking lot to prevent leakage due to rainfall. Various types of waterproofing methods are used for this purpose, and mainly, mortar liquid waterproofing, water-soluble or oil-soluble coating waterproofing, asphalt waterproofing and waterproof sheet are used.

이중 시트를 이용한 방수시공은 신축성이 우수한 합성 고무나 합성수지 또는 고무화 아스팔트 등을 주원료로 하여 일정 규격의 방수시트를 제작하여 바닥이나 벽면에 견고하게 밀착시켜 부착함으로써, 외부로부터 강우에 대처할 수 있도록 하였다.In the waterproof construction using double sheets, waterproof rubber sheets of a certain standard are made of synthetic rubber, synthetic resin or rubberized asphalt with excellent elasticity, and firmly adhered to the floor or wall to cope with rainfall from the outside. .

이러한 방수시트는 시트 형상의 방수재를 방수 공사를 하고자 하는 바닥면에 펼쳐 설치함으로써 방수층을 형성하는 방수공법으로서, 시공이 비교적 간편하고 공사기간이 단축되는 장점이 있기 때문에 오늘날 널리 이용되고 있는 방수 공법 중 하나이다.This waterproof sheet is a waterproof method for forming a waterproof layer by spreading sheet-shaped waterproof material on the floor to be waterproofed, and is widely used today because of the advantages of relatively simple construction and short construction period. One.

이러한 시트 방수에 사용되는 방수시트는 현장에서의 시공 및 취급이 용이하도록 미리 공장에서 일정한 폭 및 길이(통상 폭 1~2M, 길이 10~20M)를 갖는 롤(roll) 형의 시트의 형태로 제작되며, 이를 바닥면 위에 일정 간격으로 펼쳐 설치하게 된다.The waterproof sheet used for waterproofing the sheet is manufactured in the form of a roll-type sheet having a predetermined width and length (usually 1 to 2M in width and 10 to 20M in length) at the factory to facilitate construction and handling in the field. It is installed on a floor at regular intervals.

통상적으로 고무화 아스팔트 방수시트의 경우에는 시트의 겹침 부위를 토오치 등의 열 기구를 사용하여 가열 용융시켜 열융착하는 방식을 취하고 있고, 합성수지 또는 합성 고무 방수시트의 경우에는 접착제 또는 접착 테이프를 사용하여 접착하거나(EPDM시트, PVC시트, TPO시트 등), 용제를 사용하여 용착 한다든지(PVC 시트) 혹은 열풍 융착기를 사용하여 열풍 융착하는 방법을 사용하고 있다(PVC시트, TPO시트, ECV시트, HDPE시트 등)In general, in the case of rubberized asphalt waterproof sheet, the overlapped parts of the sheets are heated and melted by using a heat mechanism such as a torch, and heat-sealed. In the case of a synthetic resin or a synthetic rubber waterproof sheet, an adhesive or an adhesive tape is used. Epoxy sheet (EPDM sheet, PVC sheet, TPO sheet, etc.), welding using solvent (PVC sheet), or hot air fusion using hot air welding machine (PVC sheet, TPO sheet, ECV sheet, etc.). HDPE sheet, etc.)

국내의 대다수의 방수공법은 현재 복합방수공법에 취중하고 있다. 이러한 이유는 기존 시트층으로는 건물의 옥상 방수로서의 기능을 다 할 수 없었기 때문에 시트방수공정 이후에 도막을 이용한 복합공법을 지향하고 있는실정이다.Most of the waterproofing methods in Korea are currently under the combined waterproofing method. The reason for this is that the existing sheet layer was unable to fulfill the function of waterproofing the roof of the building, so the situation is oriented toward the composite method using the coating film after the sheet waterproofing process.

하지만, 상술한 바와 같은 방수시공 공사비의 증대 및 시공 공정의 복잡성 등으로 인한 하자발생 및 유지관리의 어려움이 있다.However, there is a difficulty in occurrence of defects and maintenance due to the increase in waterproof construction cost and complexity of the construction process as described above.

방수시트 시공방법으로는 전면접착형이나 부분절연형을 이용하여 시공하고 있으나 건축물의 거동대응성에 대한 대응성이 부족하여 방수층의 손상이 발생되는 현상이 계속적으로 나타나고 있다.As the waterproof sheet construction method, it is installed using the front adhesive type or the partial insulation type, but the phenomenon of damage to the waterproof layer is continuously occurring due to the lack of responsiveness to the behavior response of the building.

일반적으로, 기후변화에 따른 방수시트의 표면은 수축, 건조, 팽창작용이 수회 반복되고, 옥외에 설치되는 방수시트 경우, 자외선 노출에 의해 경화현상이 발생되어 미세한 표면크랙(잔금)이 발생하며, 이러한 크랙발생의 정도에 따라 인장 및 인열성능을 현저히 저하시키며, 특히 옥외용도(노출)의 방수시트 내구성을 현저히 떨어뜨리는 문제점이 있다.In general, the surface of the waterproof sheet according to the climate change is repeated several times, shrinking, drying, expansion, and in the case of the waterproof sheet installed outdoors, hardening occurs by exposure to ultraviolet rays to generate fine surface cracks (residues), According to the degree of crack generation, the tensile and tearing performance is significantly lowered, and in particular, the durability of the waterproof sheet for outdoor use (exposure) is significantly reduced.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로, PVC 시트의 단점인 노출에 의한 경화현상 및 이에 따른 크랙현상을 해결하여 내구성을 향상시키고, PVC 시트가 바탕면의 거동에 대하여 신축적이고 탄력적으로 순응하지 못하는 단점을 보완하여 인열강도를 향상시키면서 신축적이고 탄력적인 순응현상이 일어나도록 하며, 건물 외벽에 시공 시 단열효과가 향상될 수 있게 하는 단열 및 인열성능이 보강된 PVC 방수시트를 제공하는 데 그 목적이 있다.The present invention has been made in order to solve the above problems, to improve the durability by solving the curing phenomenon and the crack phenomenon caused by the disadvantages of the PVC sheet, and the PVC sheet is elastic and elastic with respect to the behavior of the base surface Compensating for the disadvantages of non-compliance, to increase the tear strength, elastic and elastic phenomena occur, and to provide a PVC waterproof sheet reinforced with insulation and tearing performance to improve the insulation effect during construction on the building exterior wall Its purpose is to.

상기 시트부재(102)에는 도시된 바와 같이 수직방향을 향하여 다수 개의 연결공(102a)이 관통형성되어 있으며, 이 연결공(102a)이 형성됨으로 인하여 PVC 소재가 가지고 있던 부족한 신축성이 보완될 수 있다.As shown in the sheet member 102, a plurality of connecting holes 102a are formed in a vertical direction toward the vertical direction. As the connecting holes 102a are formed, insufficient elasticity of the PVC material may be compensated for. .

즉, 바탕면의 거동에 의하여 방수시트가 신장되려 할 경우 연결공(102a)이 길이방향으로 확장되면서 신장될 수 있으며, 바탕면의 수축에 의하여 방수시트가 수축되려 할 경우에도 연결공(102a)이 축소되면서 수축될 수 있게 되는 것이다.That is, when the waterproof sheet is to be stretched by the behavior of the base surface, the connection hole 102a may be extended while extending in the longitudinal direction, and even when the waterproof sheet is to be contracted by the contraction of the base surface. This will shrink and shrink.

한편, 상기 시트부재(102)의 상부면에는 도시된 바와 같이 상부 부직포(104)가 적층되는 바, 이 상부 부직포(104)에는 제1 우레탄 조성물 또는 제2 우레탄 조성물이 함침된다.On the other hand, as shown in the upper surface of the sheet member 102, the upper nonwoven fabric 104 is laminated, the upper nonwoven fabric 104 is impregnated with a first urethane composition or a second urethane composition.

아울러, 상기 시트부재(102)의 하부면에도 도시된 바와 같이 하부 부직포(106)가 적층되는 바, 이 하부 부직포(106)에는 제1 우레탄 조성물 또는 제2 우레탄 조성물이 함침된다.In addition, as shown in the lower surface of the sheet member 102, the lower nonwoven fabric 106 is laminated, and the lower nonwoven fabric 106 is impregnated with the first urethane composition or the second urethane composition.

따라서, 상기 상부 부직포(104)와 하부 부직포(106)를 시트부재(102)의 상, 하부에 적층된 상태에서는 상부 부직포(104)의 제1 우레탄 조성물이 연결공(102a)을 통하여 하부 부직포(106)의 제2 우레탄 조성물과 합쳐지게 됨으로써, 시트부재(102)는 상부 부직포(104)와 하부 부직포(106) 및 제1 우레탄 조성물과 제2 우레탄 조성물에 의하여 상, 하 방향에서 일체화되는 효과를 가진다.Therefore, in the state in which the upper nonwoven fabric 104 and the lower nonwoven fabric 106 are stacked on and under the sheet member 102, the first urethane composition of the upper nonwoven fabric 104 is connected to the lower nonwoven fabric (a) through the connection hole 102a. By being combined with the second urethane composition of 106, the sheet member 102 has the effect of being integrated in the upper and lower directions by the upper nonwoven fabric 104 and the lower nonwoven fabric 106 and the first urethane composition and the second urethane composition. Have

결국, 상기 시트부재(102)에 형성된 연결공(102a)에는 제1 우레탄 조성물 또는 제2 우레탄 조성물이 충진됨으로써 방수효과를 유지시킬 수 있는 것이며, 상부 부직포(104)에 함침된 제1 우레탄 조성물 또는 제2 우레탄 조성물에 의하여 방수기능이 유지될 수 있는 것이다.As a result, the connection hole 102a formed in the sheet member 102 may maintain the waterproof effect by filling the first urethane composition or the second urethane composition, and the first urethane composition impregnated in the upper nonwoven fabric 104 or The waterproof function can be maintained by the second urethane composition.

여기서, 본 발명에서는 상부 부직포(104)에 제1 우레탄 조성물을 함침시키고, 하부 부직포(106)에는 제2 우레탄 조성물을 함침시켜 연결공(102a)을 통하여 상부 부직포(104)에 함침된 제1 우레탄 조성물이 제2 우레탄 조성물과 연결될 수 있도록 하는 것이 바람직하나, 본 발명에서는 이를 한정하지 않고, 다양하게 선택 조합하여 사용할 수 있다.Here, in the present invention, the first urethane composition is impregnated into the upper nonwoven fabric 104, and the lower nonwoven fabric 106 is impregnated with the second urethane composition to impregnate the first nonwoven fabric 104 through the connection hole 102a. It is preferable to allow the composition to be connected with the second urethane composition, but the present invention is not limited thereto and may be used in various combinations.

상기한 제1 우레탄 조성물과 제2 우레탄 조성물은, 폴리에테르 폴리올 수지(polyether polyol resin) 20 ~ 30 중량%와, 유기주석 화합물인 경화촉진제 0.5 ~ 1 중량%와, 가교제 0.5 ~ 3 중량%, 분산제 0.5 ~ 1 중량%, 폴리아미드계 침강방지제 0.1 ~ 2 중량%, 소포제 0.5 ~ 2 중량%, 가소제인 폴리부텐(polybutene) 8 ~ 14 중량%, 평균 입경 0.4㎛ 이하의 실리카 20 ~ 35 중량%와, 산화방지제 0.2 ~ 2 중량%, 점착부여제 5 ~ 15 중량%를 포함하여 조성하되, 점도는 130 ~ 270 mPaㆍs 범위내로 이루어지도록 한다.The first urethane composition and the second urethane composition include 20 to 30% by weight of a polyether polyol resin, 0.5 to 1% by weight of a curing accelerator which is an organotin compound, 0.5 to 3% by weight of a crosslinking agent, and a dispersant. 0.5 to 1% by weight, polyamide-based anti-settling agent 0.1 to 2% by weight, antifoaming agent 0.5 to 2% by weight, plasticizer polybutene (polybutene) 8 to 14% by weight, 20 to 35% by weight of silica having an average particle diameter of 0.4㎛ or less , 0.2 to 2% by weight of the antioxidant, 5 to 15% by weight of the tackifier, including the composition, but the viscosity is made in the range of 130 ~ 270 mPa.s.

상기한 제1 우레탄 조성물과 제2 우레탄 조성물(이하, 우레탄 조성물이라 함) 중 폴리에테르 폴리올수지는 평균 수평균 분자량이 3,000이며 2개의 수산기(-OH)와 3개의 수산기(-OH)를 가지는 폴리에테르 폴리올 수지를 사용하며, 상기 수평균 분자량을 조절함으로써 방수 도막의 파단 시 신장률 등의 물리적 특성을 조절할 수 있다.The polyether polyol resin in the first urethane composition and the second urethane composition (hereinafter, referred to as urethane composition) has an average number average molecular weight of 3,000 and has two hydroxyl groups (-OH) and three hydroxyl groups (-OH). By using an ether polyol resin, by controlling the number average molecular weight, physical properties such as elongation at break of the waterproof coating may be controlled.

상기 폴리에테르 폴리올 수지(polyether polyol resin)는 20 ~ 30 중량%를 첨가되도록 하는 것이 바람직하며, 20 중량% 미만이면 소망하는 신장율과 탄성복원력을 얻을 수 없으며, 30 중량%를 초과하면 신장율은 높아지나 탄성복원력이 현저히 떨어지고 흐름성이 좋아지므로 소망하는 기계적 물성을 얻을 수 없고 시공성이 떨어진다.The polyether polyol resin (polyether polyol resin) is preferably added to 20 to 30% by weight, if less than 20% by weight can not obtain the desired elongation and elastic restoring force, when exceeding 30% by weight is higher As elastic resilience is significantly reduced and flowability is improved, desired mechanical properties cannot be obtained and workability is poor.

상기한 우레탄 조성물 중 유기주석 화합물인 경화촉진제는 속경화를 가능하도록 하기 위해 첨가되는 것으로 친환경적인 유기주석화합물(Dibutyl tin dilaulate)을 첨가한다.In the urethane composition, a curing accelerator, which is an organotin compound, is added to enable fast curing, and an environmentally friendly organotin compound (dibutyl tin dilaulate) is added.

상기 경화촉진제는 우레탄 조성물이 완성될 때 경화 반감기를 짧게 만들어 주는 것으로서, 부직포에 함침되는 속도를 조절하며, 0.5 중량% 미만이면 경화 반감기가 짧아지게 하는 데 영향을 미치지 않고, 1 중량%를 초과하면 경화속도가 너무 짧아지게 되므로 부직포에 함침되지 않는다.The curing accelerator shortens the curing half-life when the urethane composition is completed, and controls the rate of impregnation in the nonwoven fabric. If the curing accelerator is less than 0.5% by weight, the curing half-life is not affected. The curing rate will be too short, so it will not be impregnated with nonwovens

상기한 우레탄 조성물 중 가교제는 디메틸티오톨루엔 디아민(DMTDA: Dimethylthiotoluene diamine), 메틸렌 비스(2-클로로아닐린)[MOCA: Methylene bis(2-chloroaniline)]등을 사용할 수 있으며, 전체 중량을 기준으로 0. 5 ~ 3 중량%가 바람직하다.In the urethane composition, a crosslinking agent may use dimethylthiotoluene diamine (DMTDA) or methylene bis (2-chloroaniline) [MOCA: Methylene bis (2-chloroaniline)]. 5 to 3% by weight is preferred.

상기한 우레탄 조성물 중 분산제는 멜라민합성수지계, 나프탈렌 설폰산엽계와 포리카본산계 중 적어도 하나 이상의 게면 활성제가 사용되며, 전체 중량을 기준으로 0.5 ~ 1 중량%로서, 그 범위 내에서 결합강도가 적합하게 유지될 수 있다.The dispersant in the urethane composition is at least one crab active agent of melamine synthetic resin, naphthalene sulfonic acid and polycarboxylic acid, 0.5 to 1% by weight based on the total weight, the bond strength within the range suitably Can be maintained.

상기한 우레탄 조성물 중 폴리아미드계의 침강방지제는 조성물 중 비중이 큰 실리카 등과 같은 원료들이 침전(沈澱)되는 현상을 방지하기 위해 첨가하는 것으로 일종의 분산제로서, 0.1 중량% 미만일 경우 침강방지 효과가 미비하며, 2 중량%를 초과하면 침강방지의 효과가 크게 상승하지 않으면서, 비용만 상승시키는 문제점이 발생하므로, 전체 중량을 기준으로 0.1 ~ 2 중량%를 첨가하는 것이 바람직하다.The polyamide-based sedimentation inhibitor in the urethane composition is added to prevent the precipitation of raw materials such as silica having a high specific gravity in the composition. It is a kind of dispersant, and when it is less than 0.1% by weight, the sedimentation prevention effect is insufficient. If it exceeds 2% by weight, the effect of preventing sedimentation does not increase significantly, but only a cost increases, so it is preferable to add 0.1 to 2% by weight based on the total weight.

상기한 우레탄 조성물 중 소포제는 교반중 기포발생을 억제함은 물론 상부 부직포(104) 또는 하부 부직포(106)에 도포한 후 발생하는 기포 또는 핀홀(pin hole)도 방지하며, 도포면을 평활하게 유지하기 위해 첨가되는 것으로서, 재료의 혼합 후 재료 내에 기포 발생을 차단하고 조성물의 조직을 치밀하게 만들어주는 역할을 하며 계면활성제 등을 사용할 수 있고, 실리콘 소포제는 화학적으로 안전하여 뛰어난 효과가 있는 실리콘 소포제를 사용할 수도 있으며, 전체 중량을 기준으로 0.5 중량% 미만으로 사용하는 경우 기포제거가 어려워 조성물의 물성이 저하되며 2 중량%를 초과하여 사용할 경우 기포 제거 효과는 증대하지만 표면에 슬립성 부여로 상, 하부 조성물과의 접착성능이 저하되며, 실리콘계 및 비실리콘계 소포제 중 어느 하나 또는 2 이상의 혼합물을 사용한다.The antifoaming agent in the urethane composition prevents bubble generation during stirring and also prevents bubbles or pin holes generated after applying to the upper nonwoven fabric 104 or the lower nonwoven fabric 106, and to keep the coated surface smooth. It is added in order to prevent bubbles from forming in the material after mixing of the material, and to make the composition of the composition dense. Surfactants can be used, and the silicone antifoaming agent is chemically safe, so that the silicone antifoaming agent can be used. In case of using less than 0.5% by weight based on the total weight, it is difficult to remove the air bubbles, so that the physical properties of the composition are lowered. Adhesion with the resin is lowered, and any one or two or more of silicon-based and non-silicone-based antifoam Use.

상기한 우레탄 조성물 중 폴리부텐 가소제는 자외선 노출 하에서도 매우 안정적이고, 자체적인 점착력을 가지며 분자량 및 점도가 증가할수록 점착력 증가하며, 첨가제를 사용하지 않고 염소 및 황 함량이 극히 낮아 고순도이면서 독성이 없으며, 화학적으로 안정되어 빛이나 열에 의해 쉽게 산화되지 않는 특징을 가지는 것으로서, 본 발명에서 상기와 같은 특성을 함유한 폴리부텐을 첨가하므로 종래의 단점으로 지적되어온 고온 하에서 흘러내림, 노출 시 자외선에 의한 제품의 산화, 점착 부여기능이 현저하게 저하되는 등의 단점을 해소하였다.The polybutene plasticizer in the urethane composition is very stable even under UV exposure, has its own adhesive force and increases its adhesive strength as the molecular weight and viscosity are increased, it is extremely low in chlorine and sulfur content without using an additive and is high purity and nontoxic. It is chemically stable and does not easily oxidize by light or heat. In the present invention, polybutene containing the above-mentioned properties is added, so that it flows down under high temperature, which has been pointed out as a conventional disadvantage, by exposure to ultraviolet light of the product. The disadvantages such as a significant reduction in oxidation and tackifying functions have been eliminated.

상기 가소제는 우레탄 조성물 전체 중량을 기준으로 0. 5 중량% 미만 첨가 시 가격의 인하 효과는 있으나 점착기능 상실로 자착 기능이 상실되며, 2 중량%이상 첨가할 경우 고단가로 인하여 가격 상승을 초래하며, 고온에서 흘러내리거나 시공의 불편함이 초래되며, 자외선, 열, 기타 환경에 의해 쉽게 산화되어 내후성이 떨어진다.When the plasticizer is added in an amount of less than 0.5% by weight based on the total weight of the urethane composition, the plasticizer has a lowering effect but loses the self-adhesion function due to the loss of adhesive function. It flows down at high temperatures and causes inconvenience in construction, and it is easily oxidized by ultraviolet rays, heat, and other environments, thereby deteriorating weather resistance.

상기한 우레탄 조성물 중 실리카는 밀집성을 극대화하기 위하여 평균 입경이 0.4㎛ 이하의 크기로 첨가하는 것이 바람직하고, 이 실리카는 충진재로서의 역할을 담당하게 되며, 20 중량% 미만 첨가 시 밀집성이 저하되어 소망하는 저점도 보다 더 낮은 점도를 갖게 되고, 35 중량%를 초과하게 되면 소망하는 고점도 보다 더 높은 점도를 갖게 되므로 20 ~ 35 중량%가 바람직하다.In the urethane composition, the silica is preferably added with an average particle diameter of 0.4 μm or less in order to maximize the compactness, and the silica plays a role as a filler, and when added below 20% by weight, the density decreases. 20 to 35% by weight is preferred because it will have a lower viscosity than the low viscosity, and if it exceeds 35% by weight, it will have a higher viscosity than the desired high viscosity.

특히, 본 발명에서는 제1 우레탄 조성물과 제2 우레탄 조성물을 혼용할 수 있는 것이므로, 이때, 점도의 조절은 실리카의 첨가량으로 조절할 수 있으며, 이때, 점도는 130 ~ 270 mPaㆍs 범위내로 이루어지도록 하는 것이 바람직하다.Particularly, in the present invention, since the first urethane composition and the second urethane composition may be mixed, the viscosity may be adjusted by the amount of silica added, and the viscosity may be in the range of 130 to 270 mPa · s. It is preferable.

따라서, 제1 우레탄 조성물은 130 ~ 160 mPaㆍs 범위내로 조성되고, 제2 우레탄 조성물은 220 ~ 270 mPaㆍs 범위내로 조성되도록 하는 것이 바람직하다.Therefore, the first urethane composition is preferably in the range of 130 to 160 mPa · s, and the second urethane composition is preferably in the range of 220 to 270 mPa · s.

상기한 우레탄 조성물 중 산화방지제는 혼합 페놀계 산화방지제로 라디칼기 제거제로서 1차 산화방지제로 알려져 있으며 수지를 보호하는 역할을 하는 것으로 전체 중량 기준으로 0.2 ~ 2 중량%로 함유되는 것이 바람직하다. 만일 0.2 중량% 미만으로 함유되는 경우 산화제의 역할 미비로 자외선, 열, 공기 중의 산소에 의해 쉽게 산화되어 내후성이 떨어지고, 반면에 2 중량%를 초과하여 함유되는 경우 첨가된 폴리머 중 근본적으로 자외선, 외부환경에 쉽게 산화되는 물질로 인하여, 산화방지제를 과다하게 첨가할 경우 효과보다는 제품의 단가만 상승시키는 결과만 초래하게 된다.In the urethane composition, the antioxidant is a mixed phenol-based antioxidant, which is known as a primary antioxidant as a radical group remover, and serves to protect the resin, and is preferably contained in an amount of 0.2 to 2 wt% based on the total weight. If the content is less than 0.2% by weight, it is easily oxidized by ultraviolet rays, heat, and oxygen in the air due to insufficient role of the oxidizing agent. Due to substances that are easily oxidized in the environment, excessive addition of antioxidants only results in a higher cost of the product than the effect.

상기한 우레탄 조성물 중 점착부여제는 천연수지에 석유화학 수지를 반응시킨 고분자량인 로진에스테르를 사용한다. 또한, 후기 점착력, 내열성, 결합력을 극대화하기 위해 터펜 페놀수지를 첨가할 수도 있다.In the urethane composition, a tackifier uses a high molecular weight rosin ester obtained by reacting a natural resin with a petrochemical resin. In addition, terpene phenolic resin may be added to maximize late adhesion, heat resistance, and bonding strength.

상기 점착부여제는 전체 중량을 기준으로 5 중량% 미만이 첨가될 경우, 점착기능 저하되고, 혼합 원료간의 결합 성능 향상 효과가 미미하며, 반면에 15 중량%를 초과하는 경우에는 상대적으로 저단가 원료보다 고단가인 점착부여제의 함유량 증가로 제품의 가격을 상승시키며, 유동성이 저하되는 현상을 피할 수 없어 점착기능이 오히려 저하된다.When less than 5% by weight of the tackifier is added based on the total weight, the adhesive function is lowered, the effect of improving the binding performance between the mixed raw materials is insignificant, whereas when it exceeds 15% by weight relatively low cost raw materials Increasing the content of the higher-priced tackifier increases the price of the product, the phenomenon that the liquidity is lowered is inevitable, the adhesion function is rather deteriorated.

한편, 본 발명에 따른 PVC 방수시트(110)에는 도 1에 도시된 바와 같이 시트부재(102)의 상부면, 하부면 중 적어도 어느 하나에 폴리에스터 또는 유리섬유로 이루어진 매쉬(mesh) 구조의 매쉬망(108)을 적층시켜 내구성 및 강도를 더욱 보완시킬 수 있다.Meanwhile, in the PVC waterproof sheet 110 according to the present invention, a mesh of a mesh structure made of polyester or glass fiber is formed on at least one of the upper and lower surfaces of the sheet member 102 as shown in FIG. 1. Laying the net 108 may further complement durability and strength.

상기 매쉬망(108)은 시트부재(102)와 상부 부직포(104) 또는 하부 부직포(106)가 바탕면의 거동에 의하여 수축 또는 신장되려 할 때 발생할 수 있는 슬립(slip)현상을 방지하므로, 계면이 분리되는 현상을 미연에 방지할 수 있으므로 구조적인 안정성을 제공할 수 있게 된다.Since the mesh net 108 prevents a slip phenomenon that may occur when the sheet member 102 and the upper nonwoven fabric 104 or the lower nonwoven fabric 106 try to contract or expand due to the behavior of the base surface, This separation phenomenon can be prevented in advance, thereby providing structural stability.

그리고, 상기 상부 부직포(104)와 하부 부직포(106)에는 저점도 또는 제2 우레탄 조성물이 함침된 상태이므로, 이형지를 부착시켜 탈부착 가능토록 하는 것이 바람직하다.In addition, since the upper nonwoven fabric 104 and the lower nonwoven fabric 106 are impregnated with a low viscosity or second urethane composition, it is preferable to attach and release the release paper.
