일반주택, 아파트, 및 업무용 또는 상업용 건물의 경우 사람이 거주하거나 각종 활동을 하는 공간이므로, 인간이 안전하면서도 쾌적하게 생활을 영위할 수 있는 조건을 만족시키도록 그 내장재 등이 개선되고 발전되어 오고 있다.General houses, apartments, and business or commercial buildings are spaces where people live or engage in various activities, so interior materials have been improved and developed to satisfy the conditions for humans to live safely and comfortably. .
국내 건축물의 경우 특히, 건축물의 실내마감재는 콘크리트, 석고보드, 합성수지계 제품이 주로 시공되고 있다. 석고보드는 불연내장재로서 화재에 강하고, 취급과 시공이 편해 콘크리드 건축물이나 목조건축물의 비내력벽에 광범위하게 적용되고 있다. In the case of domestic buildings, in particular, concrete, gypsum board, and synthetic resin-based products are mainly used for interior finishing materials of buildings. As a non-combustible interior material, gypsum board is widely applied to non-bearing walls of concrete and wooden buildings because it is resistant to fire and easy to handle and construct.
하지만, 석고보드는 수분 및 습기에 약해 곰팡이 발생의 가능성이 높고, 강도가 약하여 부서지기 쉬우며(나사못 유지력이 약함), 폐암의 원인물질로 알려진 라돈방사능 발생 문제를 가지고 있으며, 단열 및 흡음기능이 거의 없고, 또한, 시공 후 표면에 페인트, 벽지, 목재 및 타일접착 등 별도의 마감재 처리를 하여야 하는 문제가 있다.However, gypsum board is vulnerable to moisture and moisture, so it is highly likely to cause mold, its strength is weak, and it is fragile (the screw retaining power is weak), and it has a problem of generating radon radiation, which is known as the cause of lung cancer, and has a thermal insulation and sound absorption function. Almost none, and there is a problem in that a separate finishing material treatment such as paint, wallpaper, wood and tile adhesion on the surface after construction is required.
합성수지계 제품은 가볍고 수분차단 능력이 우수하고, 경제적이기는 하나, 화재에 취약하고 단열 성능이 떨어지며, 결로발생 등 습도조절 기능에 문제가 있다. Synthetic resin-based products are lightweight, have excellent moisture barrier ability, are economical, but are susceptible to fire, poor insulation performance, and have problems with humidity control functions such as condensation.
한편, 사계절이 뚜렷한 국내에서는 여름철 실내의 높은 습도와 겨울철의 낮은 습도는 각종 바이러스, 곰팡이 등 미생물의 발생의 원인이 되고 있으며, 이로 인한 질병발생, 면역력 약화 등이 문제되고 있다. 이러한 습도문제를 고려하여, 2018년 국가 녹색인증 적합성 기준(첨단그린주택·도시(대분류), 저에너지 친환경주택(중분류), 기능성 건축자재(소분류))에 흡습/방습 기술이 분류되어 있다(녹색인증을 받기 위한 제품의 평가기준은 12 시간 내 흡·방습량 평균 65g/㎡이상임).On the other hand, in Korea, where the four seasons are distinct, high humidity indoors in summer and low humidity in winter are the causes of the generation of microorganisms such as viruses and fungi, resulting in disease occurrence and weakening of immunity. In consideration of this humidity problem, moisture/moisture absorption technologies are classified in the 2018 national green certification conformity standards (high-tech green houses/city (large classification), low-energy eco-friendly housing (medium classification), functional building materials (small classification)) (green certification). The evaluation standard of the product for receiving the product is an average of 65g/㎡ or more of moisture absorption and moisture absorption within 12 hours).
목재나 목제품의 경우, 천연목재의 아름다운 재색과 무늬결, 목재 천연의 향을 제공하고, 조습기능, 비강도, 단열, 흡음성 및 치수안정성과 가공성이 우수하다고 알려져 있다. 하지만, 이러한 목재나 목제품의 경우에도 녹색 인증에서 제시하고 있는 흡습과 방습 기준을 만족시키지는 못하고 있다. In the case of wood or wooden products, it is known that it provides the beautiful color and texture of natural wood, the natural scent of wood, and has excellent humidity control function, specific strength, heat insulation, sound absorption, dimensional stability and processability. However, even such wood or wooden products do not satisfy the moisture absorption and moisture-proof standards suggested by the green certification.
도 1과 도 2는 목재 절단면에 따른 3단면을 보여준다. 도 1과 도 2를 참고하면, 목재는 섬유방향(횡단면)을 따라 수분이 주로 이동하는데, 이것은 목재 횡단면에서 흡습과 방습이 가장 원활함을 의미한다. 일반적으로 횡단면의 수분이동은 접선단면과 방사단면의 10~15배 정도이다. 1 and 2 show three cross-sections according to the cut surface of the wood. Referring to FIGS. 1 and 2, moisture mainly moves along the fiber direction (cross-section) of wood, which means that moisture absorption and moisture-proofing are most smooth in the cross-section of wood. In general, the water movement in the cross section is about 10 to 15 times that of the tangential and radiating sections.
도 3은 목재를 이용한 실내 마감재 시공한 사진이다. 도 3을 참고하면, 목재 건축마감재는 외부(외기)에 노출된 표면 부분이 대부분 방사단면과 접선단면으로 흡습과 방습 기능이 우수한 횡단면은 거의 노출되지 않으며, 전체 시공면적 대비 횡단면이 차지하고 있는 면적은 매우 미약하다. 이는 목재가 원기둥 형태로 되어 있으므로, 도 4와 같이 원목의 길이방향으로 제재가 되며, 제재목은 그림 5와 같은 벽면재로 최종 가공되어 바닥, 벽면, 천장 등에 시공된다. Figure 3 is a picture of the interior finishing material construction using wood. Referring to FIG. 3, in the wooden building finishing material, the surface portion exposed to the outside (outdoor air) is mostly a radial section and a tangential section, and a cross section with excellent moisture absorption and moisture-proof function is hardly exposed, and the area occupied by the cross section compared to the total construction area is It is very weak. This is because the wood is in the form of a cylinder, the sawn is made in the longitudinal direction of the log as shown in Fig. 4, and the lumber is finally processed into a wall material as shown in Fig. 5 to be installed on the floor, wall, and ceiling.
현재의 목재 제품은 흡습과 방습기능이 우수한 횡단면이 거의 외기에 노출되지 않아(도 5와 같이, 횡단면은 전체 면의 맨 끝면(횡단면)만 나타나게 됨), 목재가 가진 우수한 방습 흡습 기능을 거의 발휘하지 못하는 문제점이 있다. The current wooden products have excellent moisture absorption and moisture-proof functions, and are hardly exposed to the outside air (as shown in Fig. 5, the cross-section shows only the very end (cross-section) of the entire surface), so that the excellent moisture absorption and moisture absorption functions of wood are almost exhibited. There is a problem that cannot be done.

상기 조습제 함량에 특별한 제한이 있는 것은 아니다. 예를 들면, 5~50 중량% 조습제 조성물이 사용될 수 있다. 좀 더 바람직하게는 상기 조습제 조성물은 보드 후면이나 부직포에 100g/㎡~200g/㎡ 도포하여 건조될 수 있다. There is no particular limitation on the content of the humectant. For example, 5 to 50% by weight of a humidifier composition may be used. More preferably, the humectant composition may be dried by applying 100g/m2 to 200g/m2 to the back of the board or the nonwoven fabric.
상기 조습제는 보드 후면에 코팅됨에 따라 표면(전면) 처리시 흡습과 방습과정에서 발생할 수 있는 백화, 얼룩 등의 표면 결함이 발생하지 않는다. As the humectant is coated on the back side of the board, surface defects such as whitening and stains, which may occur during the process of moisture absorption and moisture absorption, do not occur during surface (front) treatment.
상기 부직포(20, 120)는 상기 마감재 보드의 일면에 부착되고, 상기 부직포에는 조습제가 함침된다.The nonwoven fabrics 20 and 120 are attached to one surface of the finishing material board, and the nonwoven fabric is impregnated with a humidity control agent.
상기 부직포는 공지된 부직포를 제한없이 사용할 수 있다. 상기 부직포의 두께에 대해 특별한 제한이 있는 것은 아니다. 예를 들면, 상기 부직포는 두께가 0.2~3mm 일 수 있다. As the nonwoven fabric, a known nonwoven fabric may be used without limitation.

For example, an antimicrobial agent such as borax or borate may be added in an amount of 1 to 20% by weight to the humectant composition and then applied to the nonwoven fabric.
상기 홀은 실내 수증기(수분)가 목재, 합판, 조습제 또는 조습제를 함유한 부직포로 흡습되거나 실내로 방습될 수 있는 통로를 제공할 수 있다. 즉, 건물 내의 수증기는 상기 홀을 통해 목재나 부직포 등에 흡습되거나 목재나 부직포 등으로부터 상기 홀을 통해 실내로 방습될 수 있다. 즉, 상기 홀은 통상적인 흡음 효과뿐만 아니라 마감재 후면에 부착된 부직포와 함께 실내 습도조절 효과도 제공할 수 있다.The hall may provide a passage through which indoor water vapor (moisture) can be absorbed or moisture-proofed into the room with wood, plywood, a humidity control agent, or a nonwoven fabric containing a humidity control agent. That is, water vapor in the building may be absorbed by wood or non-woven fabric through the hall, or may be moisture-proof into the room through the hall from wood or non-woven fabric. That is, the hole may provide not only a typical sound-absorbing effect, but also an indoor humidity control effect together with the nonwoven fabric attached to the rear surface of the finishing material.
또한, 마감재 보드가 목재, 합판 또는 목재-무기질 복합보드인 경우, 상기 홀은 목재 횡단면 노출면적을 높여 방습과 흡습능력을 향상시킬 수 있다. 그림 5에서 보는 바와 같이 목재의 흡습과 방습기능이 우수한 횡단면은 전체 면의 맨 끝면(횡단면)만 나타나게 되지만, 홀을 천공하게 되면, 횡단면이 홀 내측면을 통해 천공하지 않은 경우에 비해 수배에서 수십 배 이상 노출될 수 있다.In addition, when the finishing material board is wood, plywood or wood-inorganic composite board, the hole may increase the exposed area of the cross-section of wood to improve moisture-proof and moisture-absorbing ability. As shown in Fig. 5, the cross-section with excellent moisture absorption and moisture-proof function of wood shows only the very end (cross-section) of the entire surface, but if the hole is drilled, the cross-section is several to tens of times compared to the case where it is not drilled through the inner side of the hole. You may be exposed more than twice as much.
또한, 상기 목재, 합판 또는 목재- 무기질 복합 보드는 방염, 난연 또는 준불연 수지(이하, 난연수지)가 홀을 통해 내부에 함침되거나 표면(전면)에 코팅될 수 있다.In addition, the wood, plywood or wood-inorganic composite board may be impregnated with a flame-retardant, flame-retardant or semi-non-flammable resin (hereinafter, a flame-retardant resin) through a hole or coated on the surface (front).

Wood and veneer can be injected by pressing a flame retardant resin through a perforated hole. The flame retardant resin may be a known water-soluble flame retardant resin that provides a flame retardant, semi-nonflammable, or flame retardant function. For example, the flame retardant resin includes water, phosphorus flame retardants, guanidine compounds, and water-soluble glycols. The flame retardant liquid may further contain phosphoric acid as a catalyst.
목재-무기질 복합 보드는 난연수지를 단판(veneer)에 도포할 수 있다.In the wood-inorganic composite board, a flame retardant resin can be applied to the veneer.
