BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and the manner of achieving them, will be apparent from and elucidated with reference to the embodiments described hereinafter in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms, only the present embodiments to make the disclosure of the present invention complete, and common knowledge in the art to which the present invention pertains. It is provided to fully inform the person having the scope of the invention, which is defined only by the scope of the claims. Like reference numerals refer to like elements throughout.

도 1은 본 발명의 일 실시예에 따른 무기질 보드용 표면 방수지를 나타낸 단면도이다.1 is a cross-sectional view showing a surface waterproof paper for inorganic board according to an embodiment of the present invention.

먼저 도 1을 참조하면, 셀룰로오스 섬유(Cellulose fiber), 유리 섬유(glass fiber) 및 유기질 섬유(organic fiber)로 이루어진 혼용 부직포(100)가 구비된다. 이때, 혼용 부직포는 셀룰로오스 섬유 30 ~ 70 중량%, 유리 섬유 28 ~ 60 중량% 및 유기질 섬유 2 ~ 20 중량%를 포함하는 조성으로 이루어진 것을 사용하는 것이 바람직하다.First, referring to FIG. 1, a mixed nonwoven fabric 100 made of cellulose fibers, glass fibers, and organic fibers is provided. At this time, it is preferable to use a mixed nonwoven fabric having a composition containing 30 to 70% by weight of cellulose fibers, 28 to 60% by weight of glass fibers and 2 to 20% by weight of organic fibers.

또한, 셀룰로오스 섬유는 평균 직경이 5 ~ 100㎛이고, 평균 길이가 1 ~ 30mm인 것들을 사용하는 것이 바람직하다.Moreover, it is preferable to use those whose cellulose fiber is 5-100 micrometers in average diameter, and whose average length is 1-30 mm.

여기서, 셀룰로오스 섬유는 부직포의 평균 기공 크기(pore size)를 조절하는 역할을 하는데, 셀룰로오스 섬유의 중량비가 30 중량% 미만으로 첨가되거나, 상기 평균 크기에 미치지 못하는 것들이 다수 혼합된 경우에는 기공 크기가 지나치게 커져서 방수 특성이 저하될 우려가 있다.Here, the cellulose fiber serves to control the average pore size of the nonwoven fabric, and when the weight ratio of the cellulose fiber is added in less than 30% by weight, or when a plurality of things that do not reach the average size are mixed, the pore size is excessively large. There is a fear that the waterproofing properties are reduced.

그리고, 반대로, 셀룰로오스 섬유의 중량비가 70 중량%를 초과하거나, 상기 평균 크기 범위를 벗어날 경우에는 상대적으로 유리 섬유(glass fiber) 또는 유기질 섬유(organic fiber)의 양이 지나치게 증가되어서 혼용 부직포의 인장강도가 저하될 우려가 있다.
On the contrary, when the weight ratio of cellulose fibers exceeds 70 wt% or the average size range is exceeded, the amount of glass fibers or organic fibers is relatively increased so that tensile strength of the mixed nonwoven fabric is increased. There is a risk of deterioration.

또한, 유리 섬유 및 유기질 섬유 각각의 평균 직경은 5 ~ 20㎛, 평균 길이는 1 ~ 30mm인 것을 사용하며, 유리 섬유 28 ~ 60 중량% 및 유기질 섬유 2 ~ 20 중량%를 포함하는 조성을 사용하는 것이 바람직하다.In addition, the average diameter of each of the glass fiber and the organic fiber is 5 to 20㎛, the average length is used 1 to 30mm, it is to use a composition containing 28 to 60% by weight of glass fiber and 2 to 20% by weight of organic fiber desirable.

여기서, 유리 섬유는 혼용 부직포의 강도 및 내수 강도를 확보하는 역할을 하며, 그에 따른 치수 안정성을 확보하는 구성인데, 유리 섬유가 28 중량% 미만으로 첨가되거나 상기 평균 크기 범위를 벗어날 경우에는 혼용 부직포의 강도가 약해질 수 있고, 유리섬유의 함량이 60 중량%를 초과할 경우에는 기공 크기가 과다하게 증가되어 방수 특성이 약해질 수 있다.Here, the glass fiber serves to secure the strength and water resistance of the mixed nonwoven fabric, and thereby secures dimensional stability. When the glass fiber is added in an amount less than 28% by weight or outside the average size range, The strength may be weakened, and when the content of the glass fiber exceeds 60% by weight, the pore size may be excessively increased to weaken the waterproofing property.

그리고, 유기질 섬유는 혼용 부직포의 유연성을 부여하면서도, 일정 내수 강도와 접힘 성형 강도를 유지하는 역할을 하는데, 유기질 섬유의 함량이 2 중량% 미만이거나 상기 평균 크기 범위를 벗어날 경우에는 혼용 부직포의 유연성이 저하될 수 있으며, 유기질 섬유의 함량이 20 중량%를 초과할 경우에는 기공의 크기가 과다하게 증가되어 방수 특성 및 강도 특성이 저하될 수 있다.In addition, the organic fiber provides flexibility of the mixed nonwoven fabric, but also serves to maintain a constant water resistance and folding molding strength. When the content of the organic fiber is less than 2% by weight or outside the average size range, the flexibility of the mixed nonwoven fabric is reduced. When the content of the organic fiber exceeds 20% by weight, the pore size may be excessively increased, thereby deteriorating the waterproofing property and the strength property.

다음으로, 상기 혼용 부직포(100)는 0.1 ~ 3 중량%의 건조지력 증강제 또는 습윤지력 증강제를 더 포함한다. 이때, 상기 건조지력 증강제는 전분 또는 폴리아 크릴아미드를 포함하고, 상기 습윤지력 증강제는 요소 포름알데히드수지, 멜라민 포름알데히드수지, 폴리아미드수지, 글리옥실화 폴리아크릴 아미드 수지 및 폴리에틸렌 이민 수지 중 하나 이상을 포함 한다.Next, the mixed nonwoven fabric 100 further includes a dry strength enhancer or a wet strength enhancer of 0.1 to 3% by weight. In this case, the dry strength enhancer comprises starch or polyacrylamide, and the wet strength enhancer comprises at least one of urea formaldehyde resin, melamine formaldehyde resin, polyamide resin, glyoxylated polyacrylamide resin, and polyethylene imine resin. Include.

상기와 같은 건조지력 증강제 또는 습윤지력 증강제는 무기질 보드가 사용되는 용도에 따라서 선택적으로 추가 될 수 있다.Dry strength enhancer or wet strength enhancer as described above may be optionally added depending on the use of the inorganic board.

이상에서 설명한 혼용 부직포의 원료들은 0.25 ~ 0.55mm의 두께로 형성되는 것이 바람직하다. 그리고, 이때의 혼용 부직포 평량은 30 ~ 100g/m2 인 단일층 부직포인 것이 바람직하다.The raw materials of the mixed nonwoven fabric described above are preferably formed to a thickness of 0.25 ~ 0.55mm. In addition, it is preferable that the mixed nonwoven fabric basis weight at this time is a single layer nonwoven fabric of 30-100 g / m <2> .

여기서, 혼용 부직포의 두께는 실질적으로 도 1에 도시된 혼용 부직포(100) 및 방수 코팅액 침투층(110) 두께가 혼합된 두께를 말하는데, 그 두께가 0.25mm 미만으로 형성되는 경우에는 방수지로서의 기능을 수행하기 어렵고, 0.55mm를 초과하는 두께로 형성되는 경우에는 방수지에서 필요한 투기성이 저하될 수 있다.Here, the thickness of the mixed nonwoven fabric substantially refers to the thickness of the mixed nonwoven fabric 100 and the waterproof coating solution penetration layer 110 shown in FIG. 1, and when the thickness is formed to be less than 0.25 mm, it functions as a waterproof paper. If it is difficult to perform and is formed to a thickness of more than 0.55mm, the air permeability required in the waterproof paper may be lowered.

아울러, 상기 혼용 부직포의 평량이 30g/m2 미만인 경우에도 방수지 기능이 저하될 수 있으며, 100g/m2 을 초과하는 경우에도 투기성이 저하될 수 있다.
In addition, even if the basis weight of the mixed non-woven fabric is less than 30g / m 2 may be reduced the waterproof paper function, even if it exceeds 100g / m 2 may be reduced in air permeability.

본 발명에 따른 방수지는 상기와 같은 구조의 혼용 부직포 상부에 형성되는 방수 코팅층(120)을 포함하는 구조를 갖는다.The waterproof paper according to the present invention has a structure including a waterproof coating layer 120 formed on the mixed nonwoven fabric of the above structure.

여기서, 방수 코팅층(120)은 아크릴 바인더 고형분 3 ~ 30 중량%, 물 10 ~ 50 중량%, 무기필러 20 ~ 70 중량%, 발수제 0.5 ~ 10 중량%, 안료 0.5 ~ 5 중량% 및 항균제 0.2 ~ 5 중량%를 포함하는 방수 코팅액으로 형성된 것을 특징으로 한다.Here, the waterproof coating layer 120 is an acrylic binder solid content of 3 to 30% by weight, water 10 to 50% by weight, inorganic filler 20 to 70% by weight, water repellent 0.5 to 10% by weight, pigment 0.5 to 5% by weight and antibacterial 0.2 to 5 Characterized in that formed of a waterproof coating solution containing a weight%.

이때, 상기 무기 필러는 평균 입도가 5 ~ 50㎛인 CaCO3를 사용 하고, 상기 발수제는 탄화플루오르계 또는 왁스계 발수제를 사용하는 것이 바람직하다.At this time, the inorganic filler is used CaCO 3 having an average particle size of 5 ~ 50㎛, the water repellent is preferably used a fluorocarbon or wax-based water repellent.

여기서, 상기 방수 코팅액의 점도는 50 ~ 500 cps이 되도록 하는 것이 바람직하다. 방수 코팅액의 점도가 50 cps 미만일 경우에는 코팅액이 혼용 부직포 내에 침투되는 양이 감소되어, 방수 코팅층(120)이 쉽게 분리될 수 있고, 점도가 500 cps를 초과하는 경우에는 혼용 부직포 내에 침투되는 양이 지나치게 증가되어 무기질 보드와의 접착성을 저하시킬 수 있다.Here, the viscosity of the waterproof coating liquid is preferably to be 50 ~ 500 cps. When the viscosity of the waterproof coating liquid is less than 50 cps, the amount of the coating liquid penetrates into the mixed nonwoven fabric is reduced, so that the waterproof coating layer 120 can be easily separated. When the viscosity exceeds 500 cps, the amount penetrated into the mixed nonwoven fabric is increased. It may increase excessively and may degrade adhesiveness with an inorganic board.

따라서, 상기 점도 범위 내에서 방수 코팅액은 30 ~ 200 g/m2 양으로 코팅되도록 하는 것이 바람직하며, 이때의 방수 코팅층(120)은 혼용 부직포 상부 표면에서부터 중심부 방향의 두께를 기준으로 5 ~ 80% 범위까지 침투된 코팅 구조를 갖는 것이 바람직하다.Therefore, the waterproof coating solution within the viscosity range is preferably to be coated in an amount of 30 ~ 200 g / m 2 , wherein the waterproof coating layer 120 is 5 to 80% based on the thickness of the central direction from the upper surface of the mixed nonwoven fabric It is desirable to have a coating structure penetrated to the extent.

아울러, 상기와 같은 방수 코팅액의 코팅량 및 코팅층의 침투 범위 또한 상기 점도의 영향과 같이 각 최저 범위 미만일 경우 코팅층이 쉽게 박리될 우려가 있으며, 각 최고 범위를 초과할 경우에는 방수지의 접착성이 저하될 수 있다.
In addition, the coating amount of the waterproof coating solution as described above and the penetration range of the coating layer may also be easily peeled off when the coating layer is less than each minimum range, such as the effect of the viscosity, the adhesiveness of the waterproof paper is lowered when exceeding each maximum range. Can be.

본 발명에 따른 무기질 보드용 표면 방수지는 혼용 부직포(100+110) 단일층에 방수 코팅층(110+120)이 코팅된 형태를 갖는다. 이때, 방수 코팅층 미 침투 영역(100)의 상기 혼용 부직포 평균 기공 크기(Pore size)는 10 ~ 100㎛이고, 방수 코팅층(120)이 침투된 방수 코팅액 침투층(110)의 상기 혼용 부직포 평균 기공 크기는 5 ~ 50㎛인 것이 바람직하다. 여기서, 상기 기공 크기가 각 조건 범위 중 최저 범위 미만으로 형성될 경우 제조가 용이하지 못하며 투기성이 저하될 수 있고, 각 조건 범위 중 최대 범위를 초과하는 경우에는 방수성이 저하될 수 있다.The surface waterproofing paper for the inorganic board according to the present invention has a form in which a waterproof coating layer 110 + 120 is coated on a single layer of a mixed nonwoven fabric (100 + 110). At this time, the mixed nonwoven fabric average pore size (Pore size) of the waterproof coating layer non-penetrating region 100 is 10 ~ 100㎛, the mixed nonwoven fabric average pore size of the waterproof coating liquid penetration layer 110 in which the waterproof coating layer 120 is penetrated. It is preferable that it is 5-50 micrometers. Here, when the pore size is formed below the minimum range of each condition range, manufacturing is not easy and air permeability may be lowered, and when the pore size exceeds the maximum range range, the waterproofness may be reduced.

또한, 상기 방수 코팅층을 포함하는 표면 방수지 전체 두께는 0.27 ~ 0.57mm인 것이 바람직하다. 여기서, 상기 표면 방수지의 전체 두께가 0.27mm 미만으로 형성될 경우 방수성이 저하될 수 있고, 0.57mm를 초과하는 경우에는 투기성이 저하되어, 무기질 보드에 접착되는 표면 방수지로서의 특성이 저하될 수 있다.In addition, the total thickness of the surface waterproof paper including the waterproof coating layer is preferably 0.27 ~ 0.57mm. In this case, when the total thickness of the surface waterproof paper is less than 0.27 mm, the waterproof property may be reduced. When the surface waterproof paper is more than 0.57 mm, the air permeability may be lowered, and thus the characteristics of the surface waterproof paper adhered to the inorganic board may be degraded.

이때, 무기질 보드는 중질섬유판(Medium Density Fibreboard; MDF), 합판, 무석면 섬유강화 시멘트(Cellulose fiber Reinforced Cement) 보드, 마그네슘보드, 집성목, 고밀도섬유강화 (High density fiber (High density fiberboard), 세라믹타일, 포셀린타일, 세라믹보드, 석고보드, 시멘트보드 및 MgO보드 중 하나 이상이 사용될 수 있다.In this case, the inorganic board is a medium density fiber board (MDF), plywood, cellulose fiber reinforced cement (Cellulose fiber Reinforced Cement) board, magnesium board, aggregate wood, high density fiber (High density fiberboard), ceramic tile, One or more of porcelain tile, ceramic board, gypsum board, cement board and MgO board may be used.

아울러, 상기 방수성 및 투기성은 하기 실시예 및 실험 결과들을 통하여 더 상세히 설명하는 것으로 한다.In addition, the waterproof and air permeability will be described in more detail through the following examples and experimental results.

이때, 본 발명에 따른 표면 방수지 제조 방법에 대하여 설명하면 다음과 같다.At this time, when the surface waterproof paper manufacturing method according to the present invention will be described.

도 2는 본 발명의 일 실시예에 따른 무기질 보드용 표면 방수지를 제조하는 방법을 나타낸 순서도이다.Figure 2 is a flow chart showing a method of manufacturing a surface waterproof paper for inorganic board according to an embodiment of the present invention.

도 2를 참조하면, 먼저 본 발명의 일 실시예에 따른 무기질 보드용 표면 방수지 제조 방법은 셀룰로오스 섬유(Cellulose fiber), 유리 섬유(glass fiber) 및 유기질 섬유(organic fiber)를 혼합하여 혼용 부직포를 제조하는 단계(S100)와, 아크릴 바인더 고형분, 물, 무기필러, 발수제, 안료 및 항균제를 포함하는 방수 코팅액을 제조하는 단계(S110) 및 상기 혼용 부직포 상부에 상기 방수 코팅액을 도포하고, 건조시키는 단계(S120)를 포함한다.Referring to Figure 2, first, the surface waterproof paper manufacturing method for an inorganic board according to an embodiment of the present invention to produce a mixed nonwoven fabric by mixing cellulose fibers (Cellulose fiber), glass fibers (glass fibers) and organic fibers (organic fibers) Step (S100), and preparing a waterproof coating liquid containing acrylic binder solids, water, inorganic fillers, water repellents, pigments and antibacterial agents (S110) and applying the waterproof coating liquid on the mixed nonwoven fabric, and drying ( S120).

여기서, 혼용 부직포 제조 단계(S100) 방수 코팅액 제조 단계(S110)는 순차적으로 도시되었으나, 이들은 각각 독립된 제조 과정이므로 반드시 순차적으로 이루어져야 할 필요는 없다.Here, the mixed non-woven fabric manufacturing step (S100) waterproof coating liquid manufacturing step (S110) is shown in sequence, but these are not necessarily necessarily made sequentially because each is an independent manufacturing process.

아울러, 혼용 부직포 및 방수 코팅액의 조성이나 함량 범위는 상기 도 1에서 기술한 바와 같다.In addition, the composition or content range of the mixed nonwoven fabric and the waterproof coating solution is as described in FIG.

다음으로, 방수 코팅액을 도포하는 방법은 드럼(Drum) 코팅, 롤(Roll) 코팅, 나이프(Knife) 코팅 및 콤마(Comma) 코팅 중 선택되는 하나의 방법으로 수행하고, 건조는 100 ~ 200℃의 온도에서 1 ~ 10 분 동안 수행하는 것이 바람직하다.Next, the coating method of the waterproof coating liquid is performed by one method selected from drum coating, roll coating, knife coating, and comma coating, and drying is performed at 100 to 200 ° C. Preference is given to performing at temperatures for 1 to 10 minutes.

여기서, 건조 온도가 100℃ 미만이거나, 건조시간이 1분 미만일 경우에는 방수 코팅층이 정상적으로 형성되지 못하고, 건조 온도가 200℃를 초과하거나, 건조시간이 10분을 초과할 경우에는 방수 코팅층이 손상되어 방수성이 저하될 수 있다.
Here, when the drying temperature is less than 100 ℃ or the drying time is less than 1 minute, the waterproof coating layer is not formed normally, when the drying temperature exceeds 200 ℃, or when the drying time exceeds 10 minutes, the waterproof coating layer is damaged Waterproofness may be degraded.

도 3은 본 발명의 일 실시예에 따른 무기질 보드용 표면 방수지를 제조하는 방법을 나타낸 개략도로, 상기 방수 코팅액을 도포하는 방법 중에서 드럼(Drum) 코팅 방법을 나타낸 것이다. Figure 3 is a schematic diagram showing a method for producing a surface waterproof paper for inorganic board according to an embodiment of the present invention, it shows a drum (Drum) coating method of the method of applying the waterproof coating liquid.

도 3을 참조하면, 코팅용 드럼(220)을 이용하여 혼용 부직포 롤(200)에서 혼용 부직포(210)를 연속적으로 언코일링(Uncoiling) 되도록 한다.Referring to FIG. 3, the mixed nonwoven fabric 210 is continuously uncoiled in the mixed nonwoven fabric roll 200 using the coating drum 220.

이때, 코팅용 드럼(220)은 혼용 부직포(210)의 일면에만 방수 코팅액(230)이 도포될 수 있도록, 방수 코팅액(230)이 담겨 있는 코팅액 용기(240) 내에서, 혼용 부직포(210)의 일면이 완전히 차단될 수 있도록 한다.At this time, the coating drum 220 in the coating liquid container 240 containing the waterproof coating liquid 230 so that the waterproof coating liquid 230 can be applied only to one surface of the mixed nonwoven fabric 210, the mixed nonwoven fabric 210 Make sure one side is completely blocked.
