Description

건축 내장재용 황토판넬 제조방법{Method for manufacturing loess panel for construction interior}FIELD OF THE INVENTION [0001] The present invention relates to a method for manufacturing a roofing panel for building interior materials,

본 발명은 친환경적이면서 가격이 저렴하고 가벼우며 원적외선 방출효과가 뛰어나면서 난연성, 내수성, 내습성이 향상된 건축 내장재용 황토판넬 제조방법에 관한 것이다.
The present invention relates to a method for producing a yellow clay panel for an architectural interior material having improved flame retardance, water resistance and moisture resistance while being eco-friendly, low in cost, light in weight, and excellent in far-infrared radiation effect.

일반적으로 건축물의 벽체, 천정제 및 바닥제의 단열 시공방법으로는 콘크리트 슬래브상에 발포폴리스틸렌폼이나, PE필름, 마감 몰탈 등을 사용하거나, 특수 방음 보드나 암면, 유리면을 완충재로 사용하는 것이 일반적인 경향이다.Generally, it is common to use foamed polystyrene foam, PE film, finishing mortar, etc. on concrete slabs, or use special soundproof boards, rock surfaces, and glass surfaces as cushioning materials as insulation methods for walls, ceilings, to be.

상기한 건축 내장재들은 단열, 방음효과에만 치중하고 있어 건축 폐기물의 처리나 인체에 대한 유해성을 고려하고 있지 않아 심각한 사회 문제로 대두되고 있어 근래에는 상기한 문제점을 감안하여 건축 내장재로 황토 판넬을 개발하여 사용하고 있다.The above-mentioned architectural interior materials concentrate only on the heat insulation and the sound insulation effect, and do not take into account the treatment of building waste and the harmfulness to the human body, so that they become serious social problems. In recent years, I am using it.

상기 황토 판넬은 대한민국 등록특허 제10-121997호(이하, '특허문헌 1'이라 함.)에 제안된 바 있다.The above yellow clay panel has been proposed in Korean Patent No. 10-121997 (hereinafter referred to as "Patent Document 1").

상기 특허문헌 1은 정선된 황토 68%, 폐지펄프 30%의 혼합물에 물풀 2%를 가교재로 한 혼합 조성물에 20%의 물을 붓고 토련기로 반죽해 압출한 소지를 압축로울러로 일정 두께의 평판넬로 규격 성형한 다음 80~150 열풍 콘베어라인에 2시간 정도 노출시켜 고결함을 특징으로 하고 있다.In Patent Document 1, 20% of water is poured into a mixed composition of a mixture of 68% of selected yellow loess and 30% of pulp pulp, and 2% of water is added to the mixture, and the paper is kneaded with a kneader and kneaded. Nello is molded and exposed to 80 ~ 150 hot air conveyor line for about 2 hours.

상기 특허문헌 1은 판넬이 30%이상의 수분을 흡수하면 물풀의 영양성분이 공기중의 미생물과 결합하여 변질되어 실내의 공기를 오염시킬 가능성이 농후한 문제점이 있었다.In Patent Document 1, when the panel absorbs moisture of 30% or more, there is a problem that the nutrients of the waterfowl are combined with the microorganisms in the air and are changed to contaminate air in the room.

이러한, 문제점을 해결하기 위해 대한민국 등록특허 제10-0344930호(이하, '특허문헌 2'라 함.)가 제안된 바 있다.In order to solve such a problem, Korea Patent No. 10-0344930 (hereinafter referred to as Patent Document 2) has been proposed.

상기 특허문헌 2는 함수율 40 ∼ 45%, 입자크기 0.5mm로 분쇄된 황토분말 45중량%, 함수율 40 ∼ 45%, 입자크기 0.55mm 정도의 톱밥을 45중량%, 액상규산나트륨 10 중량%의 비율로 버티칼믹서로 혼합한 조성물을 토련기로 압출한 후 일측면 또는 양측면이 200 ∼ 500℃로 가열된 프레스로 압축 성형한 다음 2 ∼ 3초 동안 고결하여 표면을 유리화시킴으로써 우수한 강도, 내화성, 방음효과, 실내장식효과, 낙서방지효과를 얻을 수 있었다.
Patent Document 2 discloses a slurry containing 45 wt% of loess powder, 40 to 45% of moisture content, 45 wt% of sawdust having a particle size of 0.55 mm, and 10 wt% of liquid sodium silicate with a water content of 40 to 45% The composition mixed with a vertical mixer was extruded by a gypsum machine and compression-molded into a press heated to 200 to 500 ° C on one side or both sides, followed by vitrification for 2 to 3 seconds to vitrify the surface, whereby excellent strength, fire resistance, Indoor decoration effect, and anti-graffiti effect.

하지만, 상술한 특허문헌 2의 경우 목재칩이 포함되어 있어 화재에 매우 취약한 문제가 있었다.However, in the case of the above-described Patent Document 2, a wood chip is included, which is very vulnerable to fire.

물론, 상기 특허문헌 2에서 가교제로서 사용하는 액상규산나트륨은 목재에 어느 정도의 난연성을 부여하지만 톱밥과 함께 고르게 교반된 상태이기 때문에 톱밥이 화재에 취약한 문제점을 그대로 내포하고 있으며, 특히, 수분이 흡수될 경우 톱밥을 압축해서 만든 특허문헌 2는 뒤틀림 현상이 발생하게 되어 쉽게 변형되는 문제점이 있었다.
Of course, the liquid sodium silicate used as the crosslinking agent in the above Patent Document 2 gives a certain degree of flame retardancy to the wood, but since it is stirred well with the sawdust, the sawdust is vulnerable to fire, Patent Document 2 which is made by compressing sawdust has a problem that it is easily deformed due to occurrence of a twist phenomenon.

상기와 같은 문제점을 해결하기 위한 본 발명에 따른 건축 내장재용 황토판넬 제조방법은 난연성을 부여하여 화재에 안전한 건축 내장재용 황토판넬 제조방법을 제공하는데 그 목적이 있다.In order to solve the above problems, the present invention provides a method for manufacturing a clay panel for building interior materials, which is provided with flame retardancy and is safe for fire.

본 발명의 또 다른 목적은 황토분말 사이에 물리적으로 기공을 형성하여 원적외선 방출량을 향상시킬 수 있도록 하는데 있다.
Another object of the present invention is to physically form pores between the loess powder to improve the emission amount of far-infrared rays.

본 발명은 목재칩을 액상규산나트륨을 이용해 코팅하여 난연성을 부여할 수 있다.The present invention can impart flame retardancy by coating wood chips with liquid sodium silicate.

아울러, 황토분말 표면에 왁스를 코팅한 후 건조시에 왁스를 녹여 배출시키도록 하여 별다른 장비 및 제조공정 없이도 다수의 기공을 형성하여 원적외선 방출량을 더욱 향상시킴과 동시에 빠져나오지 못하는 위치에 배치된 파라핀 왁스를 통해서 내수성 및 내습성을 향상시킬 수 있는 유용한 발명이다.
In addition, since the wax is coated on the surface of the loess powder and then the wax is melted and dried at the time of drying, a large number of pores are formed without any equipment or manufacturing process to further improve the amount of far-infrared rays emitted and the paraffin wax Which is a useful invention capable of improving water resistance and moisture resistance.

이하에서는 본 발명에 대해 보다 구체적으로 살펴보도록 한다.Hereinafter, the present invention will be described in more detail.

우선, 본 발명에 따른 건축 내장재용 황토판넬 제조방법은 함수율 40 ∼ 45%, 입자크기 0.1 ∼ 0.5mm로 분쇄된 황토분말 45중량%, 함수율 40∼45%, 입자크기 0.5mm(가로)×2mm(세로)의 목재칩을 규산나트륨으로 코팅한 목재칩 35중량%, 액상 규산나트륨 10중량%, 입도 0.1 ∼ 0.3mm이하로 분쇄된 파라핀 왁스 10중량% 이루어진 조성물을 믹서기를 이용하여 고르게 혼합한 조성물을 프레스로 성형한 후 양 측면이 150 ∼ 250℃로 가열된 건조기에서 30 ∼ 60초 건조시켜 조성물을 고형화시킴과 동시에 파라핀왁스를 제거하여 다수의 기공이 형성되도록 가공한다.First, the method for producing a yellow clay panel for building interior materials according to the present invention comprises 45 weight% of loess powder, 40 to 45% of water content, 40 to 45% of particle size, 0.5 mm (width) (Longitudinal) wood chips coated with sodium silicate, 35 wt% of a wood chip, 10 wt% of liquid sodium silicate and 10 wt% of paraffin wax ground to a particle size of 0.1-0.3 mm or less were mixed in a mixer Is molded into a press and then dried in a dryer heated at 150 to 250 ° C for 30 to 60 seconds to solidify the composition and remove the paraffin wax to form a plurality of pores.

여기서, 상기 목재칩에 규산나트륨을 코팅하는 방법은 목재칩이 수납된 믹서기를 가동한 상태에서 액상 규산나트륨을 스프레이 방식으로 뿌려 함수율이 낮은 상태로 목재칩에 규산나트륨을 코팅하게 된다.
Here, in the method of coating the wood chips with sodium silicate, the sodium silicate is sprayed on the wood chips while the mixer in which the wood chips are housed is sprayed to coat the wood chips with sodium silicate in a low water content.

1. 코팅 황토분말1. Coated loess powder

상기 코팅 황토분말은 우선, 입자크기가 0.1 ∼ 0.5mm로 분쇄하여 황토분말을 형성된다.The coated loess powder is first pulverized to a particle size of 0.1 to 0.5 mm to form loess powder.

여기서, 상기 황토분말은 회전식 로에서 150 ∼ 200℃로 가열하여 황토 내에 포함될 수 있는 불순물을 제거함은 물론, 황토분말을 미리 열처리 함으로써 원적외선 방출량을 더욱 극대화 시킬 수 있게 된다.
Here, the loess powder is heated to 150 to 200 ° C in a rotary kiln to remove impurities that may be contained in the loess, and further, the loess powder is heat-treated in advance to maximize the amount of far-infrared rays emitted.

2. 목재칩2. Wood chip

본 발명에서의 목재칩은 0.5mm(가로)×2mm(세로)의 목재칩을 액상규산나트륨으로 코팅하여 제작된다.The wood chip in the present invention is manufactured by coating a wood chip of 0.5 mm (width) x 2 mm (length) with liquid sodium silicate.

본 발명에서의 목재칩은 종래기술에 언급한 특허문헌 2에서의 목재칩과 동일한 것으로 사용하게 된다. 다만, 목재칩에 액상규산나트륨을 코팅하여 난연성을 부여할 수 있게 된다.The wood chip in the present invention is used in the same manner as the wood chip in Patent Document 2 mentioned in the prior art. However, it is possible to impart flame retardancy by coating liquid wood silicate sodium on the wood chips.

즉, 상술한 규산나트륨은 주지하다시피 목재의 난연성을 부여하기 위해 많이 사용하며, 이때에, 목재를 액상규산나트륨에 침지시키는 것이 일반적인데, 이럴 경우 충분히 규산나트륨을 포함시켜야 하기 때문에 침지시간이 길어지게 되고, 침지된 시간이 길어질수록 이를 건조하기 위한 시간 또한 길어지게 되어 공정시간이 늘어나는 문제점이 발생하게 된다.That is, the above-mentioned sodium silicate is widely used for imparting flame retardancy to wood as it is known, and at this time, it is general to immerse the wood in liquid sodium silicate. In this case, since the sodium silicate must be sufficiently contained, The longer the immersion time is, the longer the time for drying it becomes, and the process time is increased.

하지만, 본 발명에서는 일정 입도를 가진 목재칩을 믹서기에 넣어 교반하면서 규산나트륨을 스프레이 방식으로 뿌려 코팅하기 때문에 함수율이 낮으면서 목재칩 표면에만 규산나트륨이 코팅되도록 하여 위와 같은 문제점인 가공시간을 단축할 수 있게 된다.However, in the present invention, sodium silicate is coated on the surface of a wood chip while the water content is low, because the wood chips having a certain particle size are mixed and sprayed with sodium silicate while stirring in a mixer, thereby shortening the processing time .

특히, 본 발명에서는 믹서기에 목재칩을 수납한 상태로 믹서기를 가동하여 스프레이 방식으로 액상규산나트륨을 뿌려 코팅을 하기 때문에 난연성을 부여하기 위해 목재칩을 개질시키기 위한 시간을 단축함은 물론, 후 공정에서의 시간도 단축할 수 있는 효과를 얻을 수 있다.
In particular, in the present invention, since the blender is operated in a state in which the wood chips are stored in the blender and the liquid sodium silicate is sprayed by spraying, the time for reforming the wood chip is reduced in order to impart flame retardancy, It is possible to obtain the effect of shortening the time required for the operation.

3. 액상규산나트륨3. Liquid sodium silicate

상기 규산나트륨은 규산소다라고도 한다. 조성에 따라 메타규산나트륨(Na2SiO3), 그 수화물인 오쏘규산나트륨(Na4SiO4), 이규산나트륨(Na2Si2O5) 등 여러 가지가 있으나, 보통은 메타규산나트륨을 말한다. 수화물(水和物)도 있으나, 무수물은 석영과 탄산나트륨의 혼합물을 1,000℃로 가열 융해하여 고체화(固體化)시켜서 만든다. 메타규산나트륨은 물에 잘 녹으며, 수용액은 가수분해하여 알칼리성이 된다. The sodium silicate is also referred to as sodium silicate. Depending on the composition meth sodium silicate (Na 2 SiO 3), a hydrate of ortho sodium silicate (Na 4 SiO 4), but a number of such yigyu sodium (Na 2 Si 2 O 5) , usually it refers to a meta-sodium silicate . There are hydrates, but the anhydrides are made by solidifying the mixture of quartz and sodium carbonate by heating and melting at 1,000 ℃. Sodium metasilicate dissolves well in water, and the aqueous solution becomes alkaline by hydrolysis.

이러한, 규산나트륨의 조성은 Na2O·nSiO2(n=2∼4) 이외에 소량의 Fe2O3로 구성되며, 이 중, SiO2가 난연성을 부여함은 물론, 가교제로서의 역할을 수행하게 된다.The composition of sodium silicate is composed of a small amount of Fe 2 O 3 in addition to Na 2 O.nSiO 2 (n = 2 to 4). Of these, SiO 2 not only imparts flame retardancy but also acts as a crosslinking agent do.

4. 파라핀 왁스 4 . Paraffin wax

상기 파라핀 왁스는 함랍유에서 얻어지는 상온에서 결정성 고체의 탄화수소 혼합물로서 고형파라핀이라고도 한다.The paraffin wax is also referred to as solid paraffin as a mixture of hydrocarbons of a crystalline solid obtained at room temperature obtained from embalming.

주로 곧은 사슬 파라핀으로 구성되며, 녹는점에 따라 분류되어 양초, 파라핀지 등의 제조시에 이용된다.It is mainly composed of straight chain paraffin, classified according to the melting point, and used for manufacturing candles, paraffin paper and the like.

이러한, 파라핀왁스는 방수의 효과가 높은 물질로 액체상태일 때에 침투력이 빠르고 강하면서 접착성이 뛰어나고, 액상화된 후에 양생이 빠르고 고체상태에서는 경도가 높은 특징이 있다.These paraffin waxes have a high water-proofing effect and are characterized by their fast penetration strength, strong adhesion, excellent curing after liquefaction and high hardness in a solid state.

본 발명에서 이용하는 파라핀 왁스는 녹는점은 47 ∼ 64℃인 것을 이용하여 상술한 황토분말 표면에 코팅하여 코팅 황토분말을 제작한다.The paraffin wax used in the present invention has a melting point of 47 to 64 ° C, and is coated on the surface of the above-mentioned loess powder to prepare a coated loess powder.

본 발명에서는 상기와 같은 파라핀 왁스를 이용해 별도의 가공공정 없이도 다수의 기공을 형성하여 황토분말에서 발생하는 원적외선 량을 대폭 향상시킬 수 있는 효과를 얻을 수 있다.In the present invention, by using the paraffin wax as described above, a large number of pores can be formed without a separate processing step, and the amount of far-infrared rays generated in the loess powder can be greatly improved.

즉, 황토는 주지한 바와 같이 황토분말의 크기에 의해 기공이 형성되어 다량의 원적외선을 방출하게 되며, 기공이 많을수록 더 많은 양의 원적외선이 방출하게 된다.That is, as described above, the loess is formed by the size of the loess powder, so that a large amount of far-infrared rays are emitted. The more the pores are, the more the far-infrared rays are emitted.

이에 본 발명에서는 저온에서 녹는 파라핀 왁스를 조성물이 혼합한 후 건조하는 과정에서 파라핀 왁스를 다 녹여 빼냄으로써 파라핀 왁스가 차지하고 있었던 공간이 비워져 기공이 형성되도록 하여 다량의 원적외선을 방출할 수 있는 효과를 얻을 수 있게 된다.Accordingly, in the present invention, paraffin wax melting at low temperature is mixed with the composition and dried, and then the paraffin wax is completely dissolved to remove the space occupied by the paraffin wax to form pores, thereby emitting a large amount of far-infrared rays .

특히, 상술한 파라핀 왁스는 내수성, 내습성이 뛰어나다.Particularly, the paraffin wax described above is excellent in water resistance and moisture resistance.

따라서, 외부로 배출되지 않은 위치에 있는 파라핀 왁스는 본 발명의 패널 내에 존재하여 내수성 및 내습성을 향상시키는 작용을 하게 된다.Therefore, the paraffin wax at the position not discharged to the outside is present in the panel of the present invention, thereby improving the water resistance and moisture resistance.

즉, 본 발명에서의 파라핀 왁스는 외부로 배출될 수 있는 위치에 있는 파라핀 왁스에 의해 다수의 기공을 별도의 가공 없이도 형성할 수 있으면서, 외부로 배출되기 어려운 위치에 있는 파라핀 왁스를 통해서는 내수성 및 내습성을 향상시킬 수 있는 효과를 얻을 수 있게 되는 것이다.That is, the paraffin wax of the present invention can form a large number of pores without any additional processing by the paraffin wax at a position where the paraffin wax can be discharged to the outside, It is possible to obtain an effect of improving moisture resistance.

여기서, 상술한 파라핀 왁스의 입도는 임계치 미만으로 형성할 경우 황토에 기공 형성이 어렵게 되고, 임계치를 초과할 경우 기공의 크기가 너무 커지게 되어 내구성이 문제가 된다.If the particle size of the paraffin wax is less than the critical value, it is difficult to form pores in the loess. If the paraffin wax is larger than the critical value, the size of the pores becomes too large.

또한, 파라핀 왁스의 함량을 임계치 미만으로 형성할 경우 기공 개수가 너무 적게되고, 임계치를 초과하게 되면 내구성에 문제가 발생하게 된다.
In addition, when the content of paraffin wax is less than the critical value, the number of pores becomes too small, and when the content exceeds the critical value, the durability becomes problematic.

상술한 실시 예는 본 발명의 가장 바람직한 예에 대하여 설명한 것이지만, 상기 실시 예에만 한정되는 것은 아니며, 본 발명의 기술적 사상을 벗어나지 않는 범위내에서 다양한 변형이 가능하다는 것은 본 발명이 속하는 기술분야에 종사하는 기술자에게 있어서 명백한 것이다.Although the preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
