In particular, the insulating layer is laminated on the base surface, and the non-woven fabric is laminated on the rubberized asphalt sheet layer.

종래의 대표적인 방수공법인 무기도막방수나 우레탄방수는 롤러, 스프레이, 붓 등으로 시공면에 반복적으로 칠하여 복층 방수 구조를 형성하는 방법인데, 이 방법의 경우 시공기간이 장기간 소요되고, 공정수가 많아 인건비가 많이 들며, 공정 관리가 복잡하고 불확실하고, 방수층 사이에 접착성이 약하여 박리사고가 빈발하게 되며, 시공 후에도 약간의 충격에 방수층이 파열될 우려가 있다.Inorganic coating waterproofing or urethane waterproofing, which is a typical waterproofing method of the related art, is a method of forming a multilayer waterproof structure by repeatedly painting the surface with rollers, sprays, brushes, etc. In this case, the construction period takes a long time and labor costs are high due to the large number of processes. It takes a lot, the process management is complicated and uncertain, the adhesiveness between the waterproof layer is weak and the peeling accident is frequent, there is a risk that the waterproof layer is ruptured by a slight impact even after construction.

이러한 단점을 보완하기 위한 건식 방수 방법으로 플라스틱이나 합성고무의 얇은 시트를 접착제로 부착하여 방수층을 형성하는 시트 방수 공법이 제안되었으나, 방수 시공면에 대한 사전 정리 작업을 해야 하므로 시공이 불편하며, 시공부위에 습기가 있을 경우 방수 시트와 시공면의 접착이 불가능하며 시트와 시트 사이의 이음매의 들뜸이 발생하기 쉽고, 시트 사이의 이음매가 외관상 좋지 않을 뿐 아니라 시공후 시간이 경과함에 따라 이음매가 들뜨거나 변색되는 문제점이 있다. 아스팔트시트는 열에 약하기 때문에 장기간 옥상에 노출이 되면 온도변화에 따른 수축팽창을 반복하면서 변형이 되거나 찢어지는 사고가 많이 일어나고 있다. As a dry waterproofing method to compensate for these drawbacks, a sheet waterproofing method for forming a waterproof layer by attaching a thin sheet of plastic or synthetic rubber with an adhesive has been proposed, but the construction is inconvenient because the preliminary work on the waterproofing surface is required. If there is moisture in the area, it is impossible to bond the waterproof sheet to the construction surface, and the seams between the sheets are easily lifted, and the seams between the sheets are not good in appearance, and the seams rise with time after construction. There is a problem of discoloration. Asphalt sheet is weak to heat, so when it is exposed to the roof for a long time, many accidents that deform or tear while repeating the expansion and contraction caused by temperature change occur.

고무화 아스팔트 시트(120)는 롤당 약 10m × 1m 의 길이와 폭을 가지도록 제조 공장에서 규격품으로 제조될 수 있다. 고무화 아스팔트 시트(120)는 시공면(100)을 구성하는 콘크리트층과 상부 무용제 우레탄 방수제 코팅층(140) 사이에 방습, 방진 및 방식 기능을 제공한다. 고무화 아스팔트 시트(120)는 약 2∼3 mm, 바람직하게는 약 2.5 mm 의 두께로 제공된다.The rubberized asphalt sheet 120 may be manufactured as a standard product in the manufacturing plant to have a length and width of about 10m × 1m per roll. Rubberized asphalt sheet 120 provides a moisture-proof, dust-proof and anticorrosive function between the concrete layer constituting the construction surface 100 and the upper solvent-free urethane waterproof coating layer 140. The rubberized asphalt sheet 120 is provided in a thickness of about 2-3 mm, preferably about 2.5 mm.

고무화 아스팔트 시트(120) 상에는 부직포(130)가 미리 합지되어 있는데, 부직포(130)는 고무화 아스팔트 시트(120)와 글라스화이버(140)와 무용제 우레탄 방수제 코팅층(150) 사이의 접합력을 제고하는 동시에 무용제 우레탄 방수제 코팅층(150)의 인장 강도를 증가시키는 기능을 제공하며, 부직포(130)는 100∼200g/m2 의 중량이 사용된다. 또한, 부직포(130)는 폴리프로필렌(PP) 부직포나 폴리에틸렌텔레프탈레이트(PET) 부직포를 이용한다.The nonwoven fabric 130 is laminated on the rubberized asphalt sheet 120 in advance, and the nonwoven fabric 130 is used to improve the bonding force between the rubberized asphalt sheet 120 and the glass fiber 140 and the solventless urethane waterproofing coating layer 150. At the same time provides a function of increasing the tensile strength of the solvent-free urethane waterproof coating layer 150, the nonwoven fabric 130 is used a weight of 100 ~ 200g / m2. In addition, the nonwoven fabric 130 uses a polypropylene (PP) nonwoven fabric or a polyethylene terephthalate (PET) nonwoven fabric.

고무화 아스팔트 시트(120)와 시공면(100) 사이에 절연방식으로 띄워서 적층한 단열층(110)이 있기 때문에, 시공면(100)의 균열에도 고무화 아스팔트 시트(120)나 무용제 우레탄 방수제 코팅층(150)층이 파단되는 현상이 발생하지 않을 뿐 아니라 부풀림 현상이나 박리현상이 방지될 수 있다. 또한, 시공면(100) 상에 프라이머를 도포할 필요가 없어서 공기가 단축될 뿐 아니라, 친환경적인 시공이 가능하다.Since there is a heat insulating layer 110 that is stacked in an insulating manner between the rubberized asphalt sheet 120 and the construction surface 100, the rubberized asphalt sheet 120 or the solvent-free urethane waterproofing coating layer even when the construction surface 100 is cracked ( Not only does the breakage of the layer occur, but swelling or peeling may be prevented. In addition, it is not necessary to apply a primer on the construction surface 100, not only shortens the air, but also environmentally friendly construction is possible.

한편, 부직포(130)가 합지된 고무화 아스팔트 시트(120) 상부에는 글라스화이버(140)가 적층되는데, 상기 글라스화이버층은 중량이 200∼300g/㎡이며 격자간격은 3∼5mm로된 유리섬유 직물시트로 한다. 그 상부에 무용제 우레탄 방수제 코팅층(150)이 형성되는데, 무용제 우레탄 방수제는 고무화 아스팔트 시트(120)와의 부착성이 우수하고, 내수성, 광택성, 내마모성, 내약품성 등이 우수할 뿐 아니라, 옥외 햇빛에 노출되는 경우가 많으므로 내 자외선 성이 좋으며, 기타 염분, 화학증기(산 또는 알칼리), 분진, 습기 등에도 적절한 내성을 구비하고 있다.On the other hand, the glass fiber 140 is laminated on the rubberized asphalt sheet 120 on which the nonwoven fabric 130 is laminated. The glass fiber layer has a weight of 200 to 300 g / m 2 and a lattice spacing of 3 to 5 mm. Use a fabric sheet. Solvent-free urethane waterproof coating layer 150 is formed on the upper, the solvent-free urethane waterproofing agent is excellent in adhesion with the rubberized asphalt sheet 120, as well as excellent in water resistance, gloss, wear resistance, chemical resistance, outdoor sunlight It is often exposed to UV rays, so it has good resistance to other salts, chemical vapors (acid or alkali), dust and moisture.

또한, 무용제 우레탄 방수제는, 환경호르몬 문제로 사용이 제한되고 있는 디옥틸프탈레이트(DOP), 납(Pb)과 같은 중금속 및 유기용제(Xylene, 신너 등)를 사용하지 않으면서도 용제형 도료와 유사한 물성을 가지는 장점이 있다.In addition, the solvent-free urethane waterproofing agent has properties similar to solvent-based paints without using heavy metals such as dioctylphthalate (DOP) and lead (Pb) and organic solvents (Xylene, thinner, etc.), which are limited in use due to environmental hormone problems. There is an advantage to having.

상기 무용제 우레탄 방수제는 주제와 경화제로 이루어지는 2액형 반응 경화형 방수제로서, 가지화 폴리에테르-폴리에스테르 폴리올(branched polyether-polyester polyol), 충전제(filler), 희석제(diluent), 레벨링제(levelling agent), 제습제(humidity scavenger), 소포제(air release), 자외선 차단제(ultraviolet shielding)를 포함하는 주제와, 상기 주제의 100중량부 대비 50∼100중량부의 디이소시아네이트계 화합물의 경화제로 구성되는 것을 특징으로 한다.The solvent-free urethane waterproofing agent is a two-component reaction curing type waterproofing agent consisting of a main agent and a curing agent, and a branched polyether-polyester polyol, a filler, a diluent, a leveling agent, It is characterized by consisting of a main body including a humectant (humidity scavenger), an anti-foaming agent (air release), an ultraviolet shielding (ultraviolet shielding), and a curing agent of 50 to 100 parts by weight of a diisocyanate compound relative to 100 parts by weight of the subject.

아래 표는 상기와 같이 조성되는 무용제 우레탄 방수제 조성물과 함량을 간단히 나타낸 표이다.The table below is a table briefly showing the solvent-free urethane waterproofing composition and the amount of the composition as described above.

상기와 같이 조성되는 조성물에 대하여 자세히 살펴보면 먼저, 주제인 수지(resin)에는 환경유해물질인 DOP가 포함되어 있는 기존의 폴리 우레탄 수지보다 친환경적이며 점성이 낮은 가지화 폴리에테르-폴리에스테르 폴리올(branched polyether-polyester polyol)을 이용하는 것이 바람직하며 35∼60중량부로 사용한다.Looking at the composition of the composition as described above, first, the main resin (resin) is a branched polyether-polyester polyol (branched polyether) environmentally friendly and lower viscosity than the conventional polyurethane resin containing the environmentally hazardous substance DOP -polyester polyol) is preferably used, 35 to 60 parts by weight.

다음, 원료 또는 제품의 물성보완 및 재료비 절감을 위해 충전제(filler)가 첨가되는데 충전제(filler)로는 탈크(talc), 규사(quartz powder), 탄산칼슘(CaCO3)중 어느 것을 선택적으로 하나 이상을 첨가한다.Next, a filler is added to supplement the properties of the raw material or the product and to reduce the material cost. Optionally, at least one of talc, quartz powder, and calcium carbonate (CaCO3) is added as a filler. do.

상기와 같이 충전제(filler)는 선택된 하나 이상이 첨가되어도 물성에는 큰 문제가 없으며 첨가되는 비율은 45∼70중량부의 함량이 바람직하다. 상기 함량 이상으로 첨가되었을 경우 물성이 저하될 수 있기 때문이며 상기 함량 이하로 첨가되었을 경우 상기 가지화 폴리에테르-폴리에스테르 폴리올(branched polyether-polyester polyol)의 첨가되는 양이 많아짐으로써 제품의 생산비용이 고가가 되며 일부 내마모성과 같은 물성 저하가 발생할 수 있다.As described above, even if one or more selected fillers are added, there is no significant problem in the physical properties, and the added ratio is preferably 45 to 70 parts by weight. This is because the physical properties may be lowered when added above the content, and when the amount is added below the content, the amount of branched polyether-polyester polyol is increased, thereby increasing the production cost of the product. It may cause some property degradation such as wear resistance.

그리고 소포제(air release)는 기포 발생을 억제하고 형성된 도막 내부와 외부의 기포를 제거하기 위한 것으로 실리콘 오일(silicone oil)이 사용되며 첨가되는 비율은 0.1∼2중량부를 첨가하는 것이 바람직한데 그 이유는 상기 비율 이상으로 첨가되었을 경우 접착력이 저하될 염려가 있기 때문이다.And anti-foaming agent (air release) is to suppress the generation of bubbles and to remove the bubbles inside and outside the formed film is used silicone oil (silicone oil) and the ratio is preferably added 0.1 to 2 parts by weight because It is because there exists a possibility that adhesive force may fall when it adds more than the said ratio.

그리고 무용제 우레탄 방수제의 자기 수평성을 유지하기 위해 첨가되는 레벨링제(levelling agent)로는 아크릴코폴리머(copolymer acrylate)가 사용되며 첨가되는 비율은 0.1∼3중량부로 첨가하는 것이 바람직하다. 상기 첨가제를 넣지 않을 경우 시공시에 롤러 혹은 붓의 자국이 시공표면에 남을 염려가 있기 때문이다.And as a leveling agent (levelling agent) is added to maintain the self-leveling of the solvent-free urethane waterproofing agent (copolymer acrylate) is used and the ratio is preferably added to 0.1 to 3 parts by weight. This is because when the additive is not added, the marks of the roller or the brush may remain on the construction surface during construction.

그리고 본 발명에서는 DOP와 용제가 첨가되는 기존의 용제형 우레탄 방수제의 문제점을 보완하면서도 기존의 용제형 우레탄 방수제와 유사한 물성을 가지도록 식물성 원료에서 추출한 지방산을 에스테르화한 지방산에스테르화합물(fatty acid ester)을 희석제(diluent)로 첨가하였다. 상기 지방산에스테르화합물은 식물성 지방산으로 점도를 낮추어 주는 역할을 하는데 첨가되는 비율은 1∼10중량부로 첨가되는 것이 바람직하다.In the present invention, the fatty acid ester compound obtained by esterifying the fatty acid extracted from the vegetable raw material so as to supplement the problems of the conventional solvent-type urethane waterproofing agent to which DOP and solvent are added, and have similar properties as the conventional solvent-type urethane waterproofing agent. Was added as diluent. The fatty acid ester compound serves to lower the viscosity as a vegetable fatty acid, the ratio is preferably added to 1 to 10 parts by weight.

그리고 상기 주제성분의 수분을 제거하기 위하여 제습제(humidity scavenger)로 제올라이트(zeolite powder)가 1∼10중량부 첨가된다. 상기와 같은 제습제가 첨가되는 이유는 제습제가 첨가되지 않았을 경우 제품내 수분이 경화제와 반응하여 겔 타임(GEL TIME)이 빨라짐으로써 시공상에 문제가 발생할 수 있기 때문이다.In addition, 1 to 10 parts by weight of a zeolite (zeolite powder) is added as a humidity scavenger to remove moisture of the main ingredient. The reason why the dehumidifying agent is added is that when the dehumidifying agent is not added, moisture in the product may react with the curing agent, thereby causing a problem in construction due to a faster gel time.

한편, 상기 상도 도막은 주변 환경의 영향을 직접 받기 때문에 즉, 옥외 햇빛에 직접 노출되는 경우 색상이 변할 수 있으므로 자외선차단제(ultraviolet shielding)인 티뉴빈(tinubin)을 0.1∼3중량부 첨가한다.Meanwhile, since the top coat is directly affected by the surrounding environment, that is, the color may change when directly exposed to outdoor sunlight, 0.1 to 3 parts by weight of tinubin, which is an ultraviolet shielding agent, is added.

상기와 같이 조성되는 상기 주제성분에 안료로 녹색, 백색 등을 가지는 안료분말체(pigment powder)가 1∼10중량부 더 첨가될 수 있으며 색상은 사용자의 임의의 선택에 따라 자유롭게 실시할 수 있다.1-10 parts by weight of a pigment powder having green, white, or the like as a pigment may be added to the main ingredient, which is formed as described above, and the color may be freely performed according to a user's arbitrary choice.

상기와 같이 2액형 반응 경화형 방수제 중 주제성분이 조성되면 경화제로서 디이소시아네이트계 화합물인 디이소시아네이트메틸벤젠(TDI), 디페닐메탄디이소시아네이트(MDI), 헥사메틸렌디이소시아네이트(HDI), 이소포론디이소시아네이트(IPDI)에서 선택된 어느 하나 이상을 사용할 수 있다.When the main component is composed of the two-component reaction curable waterproofing agent as described above, diisocyanate compound diisocyanate methylbenzene (TDI), diphenylmethane diisocyanate (MDI), hexamethylene diisocyanate (HDI), isophorone diisocyanate as a curing agent Any one or more selected from (IPDI) can be used.

상기 경화제 중 디이소시아네이트메틸벤젠(TDI), 디페닐메탄디이소시아네이트(MDI)는 반응성이 빨라 가사 시간이 30분 이내이며, 헥사메틸렌디이소시아네이트(HDI), 이소포론디이소시아네이트(IPDI)는 반응성이 느려 가사 시간이 하루 또는 이틀 이상 걸리기도 한다. 따라서 상기 경화제 중 작업 환경에 맞추어 가사 시간이 빠른 것과 느린 것을 알맞게 혼합하여 가사 시간을 조절하는 것이 바람직하다.Among the curing agents, diisocyanate methylbenzene (TDI) and diphenylmethane diisocyanate (MDI) have fast reactivity, and pot life is within 30 minutes, and hexamethylene diisocyanate (HDI) and isophorone diisocyanate (IPDI) have low reactivity. Housework may take a day or two or more. Therefore, it is preferable to adjust the pot life by appropriately mixing the pot life is fast and slow to suit the working environment of the curing agent.

상기와 같이 혼합된 경화제는 상기 주제성분에 상기 주제의 100중량부 대비 50∼100중량부를 첨가하여 사용한다.
The curing agent mixed as described above is used by adding 50 to 100 parts by weight based on 100 parts by weight of the main ingredient to the main ingredient.

Finally, the solvent-free urethane waterproofing agent is coated on the rubberized asphalt composite sheet to form a solvent-free urethane waterproofing coating layer 150 (S206).

한편, 무용제 우레탄 방수제는 주제를 배합하고, 배합된 주제와 경화제를 배합한 후, 주제성분과 경화제를 전동교반기(800∼1000rpm)를 이용하여 잘 혼합하여 제조한다.On the other hand, the solvent-free urethane waterproofing agent is prepared by blending the main ingredient, the blended main ingredient and the curing agent, and then mixing the main ingredient and the curing agent well using an electric stirrer (800 to 1000rpm).

이와 같이 완성된 무용제 우레탄 방수제를 상호 10∼20cm 겹쳐지도록 시공된 고무화 아스팔트 복합 시트(120)와 그 상부에 적층된 글라스화이버(140)가 함침되법은 롤라, 붓, 스프레이 방법 등을 이용할 수 있다.As such, the method of impregnating the rubberized asphalt composite sheet 120 and the glass fiber 140 laminated thereon so as to overlap the completed solvent-free urethane waterproofing material by 10 to 20 cm may be used by a roller, a brush, a spray method, or the like. .
