본 발명은 기능성 친환경 건축재에 관한 것으로서, 보다 상세하게는 경제적이고 환경친화적인 새로운 구조의 기능성 친환경 건축재에 관한 것이다.The present invention relates to a functional eco-friendly building material, and more particularly to a functional eco-friendly building material of a new structure that is economical and environmentally friendly.

몰딩부재나 창틀, 문틀 등과 같은 기존의 건축자재들은 실용성 및 디자인적 관점에서 많은 발전을 이루어왔으나, 친환경적인 면은 미진한 실정이다. 따라서 건축자재로부터 중금속이 검출되거나 또는 포름알데히드, 휘발성 유기화합물이 방출되어, 아토피와 같은 각종 피부질환을 비롯하여 기관지관련 질환 및 두통 등을 유발시키기도 한다. 또한, 종래의 건축자재들은 난연성이 확보되지 못하여 화재발생 시에 화재진압에 도움이 되지 못하고 오히려, 유독가스가 발생되어 화재진압에 방해가 된다. Existing building materials such as molding members, window frames, door frames, etc. have made much progress in terms of practicality and design, but environmentally friendly aspects are insufficient. Therefore, heavy metals are detected from building materials or formaldehyde and volatile organic compounds are released, causing various skin diseases such as atopy, as well as bronchial diseases and headaches. In addition, the conventional building materials are not secured flame retardancy does not help to extinguish the fire at the time of fire, rather toxic gas is generated to interfere with the fire extinguishing.

한편, 합성수지 사용량을 절감하고 못질 등이 쉽도록 목분 등의 유기물이 함유된 합성목재가 제공되고 있으나, 이러한 제품은 함유된 목분이 공기 중의 수분을 함유하여 곰팡이가 쉽게 발생되고, 목분이 수분을 함유하여 팽창함에 따라 건축 자재의 변형이 쉽게 유발되기도 한다. 또한, 함유된 목분이 부식 또는 노후화됨에 따라 건축자재의 강도 등이 급속히 저하되어 건축자재의 수명이 단축되는 단점도 있다.        On the other hand, synthetic wood containing organic matter such as wood powder is provided to reduce the amount of synthetic resin used and to make nailing easier. However, these products contain moisture in the air, so that mold is easily generated, and wood powder contains water. As a result of this expansion, the deformation of building materials can be easily induced. In addition, as the wood powder contained is corroded or aged, there is a disadvantage that the strength of the building material is rapidly lowered and the life of the building material is shortened.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 자원의 재활용성이 우수하고 원료가 절감되어 경제적이며, 난연성을 비롯하여 항곰팡이성 · 항균성 · 탈취성을 가지는 새로운 구조의 기능성 친환경 건축재를 제공하는 것이다.The present invention is to solve the above problems, the object of the present invention is excellent eco-use of resources, raw materials are reduced and economical, functional, eco-friendly building material of a new structure having flame retardancy, anti-mildew, antibacterial, deodorant To provide.

According to the present invention, a base portion 10 in which at least one of wood flour, chaff, and paper is mixed in a synthetic resin, and a metal oxide mixed with any one of ceramic and talc in a synthetic resin is formed on the surface of the base portion 10. A functional eco-friendly building material is provided comprising a coating 20 and a second coating 30 containing a photocatalyst and coated on the surface of the first coating 20.

본 발명의 다른 특징에 따르면, 상기 베이스부(10)는 합성수지 100Kg에 대해 목분이 35Kg 함유되고, 상기 제1피복(20)은 합성수지 100Kg에 대해 탈크 15Kg, SiO2 4Kg, Al2O3 6Kg이 함유된 것을 특징으로 하는 기능성 친환경 건축재가 제공된다. According to another feature of the present invention, the base portion 10 contains 35Kg of wood powder with respect to 100Kg of synthetic resin, and the first coating 20 has talc of 15Kg, SiO 2 4Kg, Al 2 O 3 6Kg with respect to 100Kg of synthetic resin. There is provided a functional eco-friendly building material characterized in that it contains.

According to another feature of the present invention, a functional eco-friendly building material is provided, characterized in that the first coating (20) is added with a pigment to form a pattern 22 by the non-uniform dispersion of the pigment.

본 발명의 또 다른 특징에 따르면, 상기 베이스부(10)와 제1피복(20)은 이중압출성형된 것을 특징으로 하는 기능성 친환경 건축재가 제공된다. According to another feature of the present invention, the base portion 10 and the first coating 20 is provided with a functional eco-friendly building material, characterized in that the double extrusion.

이상과 같은 구성을 가지는 본 발명은 목분, 왕겨, 종이 등의 유기물이 함유된 베이스부(10)와, 상기 제1피복(20)에 의해 커버되므로 베이스부(10)의 부식 및 노후화가 지연되며, 유기물에 수분이 흡수되어 베이스부(10)가 변형되는 것도 방지된다. 뿐만 아니라 상기 제1피복(20)은 포함된 무기물에 의해 난연성을 가진다. 따라서 화재발생시 본 발명에 의한 건축재에 의해 화재가 번지는 것이 지연되고 유독가스의 발생을 줄일 수 있는 효과를 얻을 수 있다. The present invention having the above-described configuration is covered by the base portion 10 containing the organic matter, such as wood flour, rice hull, paper, and the like, and the first coating 20, so that corrosion and aging of the base portion 10 is delayed. In addition, moisture is absorbed into the organic material and the base portion 10 is also prevented from being deformed. In addition, the first coating 20 is flame retardant by the inorganic material contained therein. Therefore, when the fire occurs, the spread of the fire by the building material according to the present invention can be delayed and the effect of reducing the generation of toxic gas can be obtained.

경우에 따라서는 제1피복(20)에는 안료가 첨가되어 색상 및 무늬가 형성된다. 상기 무늬는 안료가 고르게 분산되지 않음에 의한 무늬이며, 이와 같이 제1피복(20)에 안료를 첨가하여 색상 및 무늬를 부여하는 경우에는 베이스부(10)에 안료를 첨가하여 색상 및 무늬를 형성하는 경우에 비해 안료사용량을 줄일 수 있으므로 경제적이다. In some cases, pigments are added to the first coating 20 to form colors and patterns. The pattern is a pattern in which the pigment is not evenly dispersed, and when the pigment is added to the first coating 20 to impart color and pattern, the pattern is added to the base part 10 to form color and pattern. It is economical because the amount of pigment used can be reduced as compared to the case.

또, 본 발명은 상기 제1피복(20) 표면에 형성된 제2피복(30)에 의해 탈취, 항균, 항곰팡이성을 가진다. 또한, 본 발명은 베이스부(10)에 목분, 왕겨, 종이 들 을 사용함으로써 자원재활용성이 우수하고 환경친화적이며, 이에 따라 코스트가 저하된다. In addition, the present invention has a deodorizing, antibacterial and anti-fungal properties by the second coating 30 formed on the surface of the first coating (20). In addition, the present invention by using the wood powder, chaff, paper in the base portion 10 is excellent in resource recycling and environmentally friendly, thereby reducing the cost.

이하에서 도면을 참조하여 본 발명의 바람직한 실시예를 설명한다. 도 1은 본 발명의 일 실시예를 보인 사시도이고, 도 2는 그 단면도이다. 본 발명은 도시된 바와 같이, 베이스부(10)와, 이 베이스부(10)의 표면에 형성된 제1피복(20)과, 이 제1피복(20) 표면에 코팅된 제2피복(30)으로 이루어진 바아형태의 건축자재이다. Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. 1 is a perspective view showing an embodiment of the present invention, Figure 2 is a cross-sectional view thereof. As shown, the base portion 10, the first coating 20 formed on the surface of the base portion 10, and the second coating 30 coated on the surface of the first coating 20. It is a bar-shaped building material.

상기 베이스부(10)는 합성수지에 목분, 왕겨, 종이 중에서 적어도 하나 이상이 포함된다. 종이는 칩상태로 분쇄되어 사용된다. 이러한 베이스부(10)의 표면에 상기 제1피복(20)이 형성되는데, 이 제1피복(20)은 합성수지에 탈크, 세라믹 중에서 어느 하나와 금속산화물이 포함된다. The base portion 10 includes at least one of wood flour, rice husk, paper in the synthetic resin. Paper is used after being crushed into chips. The first coating 20 is formed on the surface of the base 10, and the first coating 20 includes any one of talc and ceramic and metal oxide in the synthetic resin.

상기 베이스부(10)는 목분, 왕겨, 종이 등의 유기물이 함유되어 있으므로 이들이 공기에 노출되면 수분을 흡수하여 팽창됨에 따라 제품의 변형이 유발되며, 또, 노후화 및 부식이 빠르게 진행될 우려가 있다. 상기 제1피복(20)은 이러한 베이스부(10)를 커버하여 베이스부(10)가 공기와 접촉되는 것을 방지함으로써, 베이스부(10)를 보호한다. Since the base portion 10 contains organic matters such as wood flour, rice hulls, paper, and the like, when they are exposed to air, they absorb moisture and expand, causing deformation of the product, and aging and corrosion may be rapidly progressed. The first coating 20 covers the base part 10 to prevent the base part 10 from coming into contact with air, thereby protecting the base part 10.

이러한 제1피복(20)에는 안료가 혼합되어 제1피복(20)에 의해 건축재에 색상 및 안료에 의한 무늬가 부여된다. 상기 베이스부(10)에 안료를 첨가하여 색상과 무늬가 형성되도록 할 수도 있으나, 베이스부(10)에 색상을 부여하거나 무늬를 형성 하는 경우에 비해 제1피복(20)에 색상을 부여하거나 무늬를 형성하는 것이 안료의 사용량을 절감시킬 수 있는 등의 이유로 경제적이다. 또한, 상기 제1피복(20)은 함유된 탈크나 세라믹, 금속산화물 등에 의해 난연성을 가진다. Pigments are mixed in the first coating 20 to impart a color and a pattern by the pigment to the building material by the first coating 20. Color and pattern may be formed by adding a pigment to the base portion 10, but to give a color or pattern to the first coating 20 as compared to the case of giving a color or pattern to the base portion 10 It is economical, for example, to reduce the amount of pigment used. In addition, the first coating 20 is flame retardant by containing talc, ceramic, metal oxide, or the like.

바람직하게는 이러한 제1피복(20)은 베이스부(10)와 이중 압출방식으로 성형된다. 이와 같이 제1피복(20)과 베이스(10)가 이중압출방식으로 성형되면 제1피복(20)을 베이스부(10)에 부착시키기 위한 별도의 과정을 거치치 않아도 될 뿐만 아니라 제1피복(20)을 부착하기 위해 별도의 접착제를 사용할 필요도 없으므로 접착제에 의한 유해물질발생 우려도 없는 장점이 있다. 상기 베이스부(10)와 제1피복(20)에 함유되는 목분, 왕겨, 종이 또는 탈크, 세라믹, 금속화합물의 함량이 높을수록 이들 성분에 의한 효과가 상승될 것이나, 이들의 함량이 놓으면 원료의 흐름성 등이 저하되어 베이스부(10)와 제1피복(20)의 성형에 문제가 발생할 수 있으므로 이러한 점을 고려하여 상기 성분들의 함유량이 조절되는데, 가장 바람직한 함유량은 후술하는 실시예에 기재된 바와 같다. Preferably, the first coating 20 is molded in a double extrusion method with the base portion 10. As such, when the first coating 20 and the base 10 are formed in a double extrusion method, the first coating 20 and the base 10 do not have to go through a separate process for attaching the first coating 20 to the base 10. 20) Since there is no need to use a separate adhesive to attach it has the advantage that there is no fear of harmful substances generated by the adhesive. The higher the content of wood flour, rice hull, paper or talc, ceramic, and metal compound contained in the base portion 10 and the first coating 20, the higher the effect of these components will be increased. Since the flowability and the like may be deteriorated and a problem may occur in forming the base part 10 and the first coating 20, the content of the above components is controlled in consideration of this point, and the most preferable content is as described in the following examples. same.

한편, 상기 제2피복(30)은 광촉매도료를 상기 제1피복(20) 표면에 코팅하여 이루어진다. 광촉매도료는 아크릴레이트 공중합체과 광촉매분말을 주성분으로 하는 것인데, 이러한 광촉매도료를 제1피복(20) 표면에 스프레이방식으로 코팅하며, 바람직하게 건조도막이 2㎛ 정도의 두께를 가지도록 코팅한다.On the other hand, the second coating 30 is made by coating a photocatalyst coating on the surface of the first coating (20). The photocatalyst coating is mainly composed of an acrylate copolymer and a photocatalyst powder. The photocatalyst coating is coated on the surface of the first coating 20 by a spray method, and preferably, the dry coating film has a thickness of about 2 μm.

<표 1>과 같은 조성을 가지는 혼합원료로 베이스부(10)와 제1피복(20)을 이 중압출방식으로 압출하여 도 1에 도시된 바와 같은 형상의 건축재를 성형하였다. 성형된 제1피복(20) 표면에 아크릴레이트 공중합체에 이산화티탄분말이 혼합된 광촉매코팅액을 스프레이하여 건조도막의 두께가 2㎛인 제2피복(30)을 코팅한 후, 30㎝ 간격으로 절단하여 다수개의 시편을 만들었다. The base material 10 and the first coating 20 were extruded by a double extrusion method using a mixed raw material having a composition as shown in Table 1 to form a building material as shown in FIG. 1. After spraying a photocatalyst coating solution containing titanium dioxide powder mixed with an acrylate copolymer on the surface of the formed first coating 20 to coat a second coating 30 having a thickness of a dry coating film having a thickness of 2 μm, cut at intervals of 30 cm. To make a number of specimens.

실시예 2는 화염방사기로 시편에 화염을 가하고, 화염방사기를 제거한 후 잔염의 지속시간과 탄화길이를 측정하였다. 그 결과 화염방사기를 제거한 후 시편에 잔염이 발생되지 않았으며, 탄화길이도 3.2㎝에 불과하다. 이를 통해 시편의 난연성이 상당히 우수함을 알 수 있다. 이러나 난연성은 무기물이 함유된 제1피복(20)에 의한 것이다.  In Example 2, the flame was added to the specimen with a flamethrower, and after the flamethrower was removed, the duration and carbonization length of the residual flame were measured. As a result, after the flamethrower was removed, no residual flame occurred on the specimen, and the carbonization length was only 3.2 cm. It can be seen that the flame retardancy of the specimen is excellent. However, the flame retardancy is due to the first coating 20 containing the inorganic material.

항곰팡이성 실험결과, <표 3>를 통해 알 수 있는 바와 같이, 4주가 경과한 후에도 균사의 발육이 인지되지 않았다. 이들 통해 시편의 항곰팡이성이 우수함을 알 수 있는데, 이러한 항곰팡이성은 상기 제1피복(20)에 의해 목분 등의 함유된 합성목재층(10)이 외부로 노출되는 것이 차단되어 베이스부(10)에 곰팡이가 발생되는 것이 방지되었을 뿐만 아니라 표면에 형성된 제2피복(30)에 곰팡이 발생이 억제되기 때문이다. As a result of the antifungal test, as shown in Table 3, even after 4 weeks, the development of hyphae was not recognized. It can be seen that the anti-fungal properties of the specimens through these, this anti-fungal properties is blocked by the first coating 20, the synthetic wood layer 10, such as wood powder is exposed to the outside base 10 This is because not only mold is prevented from occurring, but also mold is suppressed in the second coating 30 formed on the surface.
