Description
본 발명은 불연성과 내열성을 동시에 구비하도록 하는 점토류 광물을 이용한 불연성 내열판넬 및 그 제조방법에 관한 것으로서, 더욱 상세하게는 각종 화재발생시 연기나 유독가스가 발생되지 않고 고온에서 형상과 강도를 유지함으로써 인명피해를 감소시키고 재산손실을 방지할 수 있는 점토류 광물을 이용한 불연성 내열판넬 및 그 제조방법에 관한 것이다.The present invention relates to a non-combustible heat-resistant panel using a clay mineral and a method for manufacturing the same, which are provided with both non-combustible and heat-resistant at the same time, more specifically, by maintaining the shape and strength at high temperatures without generating smoke or toxic gases during various fires The present invention relates to a non-flammable heat-resistant panel using clay minerals that can reduce life damage and prevent property loss, and a method of manufacturing the same.
일반적으로, 현재 사용되는 주거용 및 산업용 건물, 선박 및 차량 등에는 각종 내외장 판넬을 필요로 하고 있으며, 이러한 판넬에는 지금까지 심재가 폴리스티렌폼이나 폴리우레탄폼으로 구성된 복합판넬이 주로 사용되어 왔고, 이러한 재질로서 이루어진 판넬은 우수한 단열성능을 가지고 있지만 불연성이 아니고 내열성이 나빠서 화재발생시 심재가 연소하면서 인체에 유해한 연기와 유독가스가 발생하고, 형태유지가 곤란하므로 판넬이 붕괴되어 인명피해와 재산손실을 야기하고 있는 실정이다.In general, currently used residential and industrial buildings, ships, and vehicles require various interior and exterior panels, and so far, composite panels composed of polystyrene foam or polyurethane foam have been mainly used. The panel made of material has excellent insulation performance, but it is non-combustible and has poor heat resistance. In case of fire, the core material burns, which causes harmful smoke and toxic gases, and forms are difficult to maintain. I'm doing it.
최근에는, 상기와 같은 판넬의 문제점을 해결하기 위하여 불연성을 구비한 암면이나 유리면을 심재로 한 복합판넬이 시판되고 있는 실정이며, 이러한 암면등을 이용한 복합판넬은, 화재발생시 연기나 유독가스가 발생치 않고 어느정도 내열성이 유지되어서 판넬이 붕괴되지 않는 현상을 나타내고 있다. Recently, in order to solve the problems of the panel as described above, composite panels based on rock wool or glass wool with nonflammable cores are commercially available, and composite panels using such rock wool generate smoke or toxic gas during a fire. In addition, the heat resistance is maintained to some extent, and the panel does not collapse.
그러나, 상기와 같이 복합판넬은, 상기 복합판넬의 심재로 사용되는 암면과 유리면은 그 자체의 내열온도(각각 약 650℃ 및 350℃)가 낮아서 두께가 두껍고 무엇보다도 장기적으로는 인체에 대한 암 발생의 위험성이 계속 제기되고 있고, 단기적으로는 피부에 접촉시 가려움증을 유발하고 호흡기질환의 문제점을 야기하고 있다.However, as described above, the composite panel, the rock surface and the glass surface used as the core material of the composite panel has a low heat resistance temperature (about 650 ℃ and 350 ℃, respectively) is thick and above all, cancer in humans in the long term Risks continue to be raised, and in the short term, itching and skin irritation cause respiratory problems.
상기한 종래 문제점을 해결하기 위한 본 발명의 목적은, 불연성이므로 화재발생시 인체에 유해한 연기나 유독가스가 발생치 않고 피부 접촉시에 문제를 야기하지 않으며 암 발생의 위험성도 전혀 제기되지 않고 있고 심재 조성물 자체의 내열도가 약 800℃ 이상으로 높아서 판넬이 붕괴되지 않고 그 형태가 유지되도록 하는 점토류 광물을 이용한 불연성 내열판넬을 제공하는데 있다.The purpose of the present invention for solving the above-mentioned conventional problems, because it is non-flammable, does not cause harmful smoke or toxic gas to the human body at the time of fire, does not cause problems during skin contact and does not pose any risk of cancer at all, the core material composition itself To provide a non-combustible heat-resistant panel using a clay mineral that has a high heat resistance of more than about 800 ℃ to maintain the shape of the panel without collapse.
또한 본 발명의 다른 목적은, 국내에 부존량이 상대적으로 풍부하여 원료의 구입 비용이 저렴하고 쉽게 활용할 수 있는 점토류 광물의 부가가치를 제고하도록 하는 점토류 광물을 이용한 불연성 내열판넬을 제공하는데 있다.In addition, another object of the present invention is to provide a non-flammable heat-resistant panel using a clay mineral to enhance the added value of the clay mineral, which is relatively rich in the amount of residual in Korea, the purchase cost of the raw material is cheap and easily utilized.
본 발명은 상기 목적을 달성하기 위하여, 경량무기물 25∼55 중량%, 무기점결제 20∼44 중량%, 경화제 및 충전제 5∼22 중량%, 발수제 0.2∼1.5 중량% 그리고 물 5∼25 중량%가 혼합되어 조성되는 점토류 광물을 이용한 불연성 내열판넬이 제공된다. In order to achieve the above object, the present invention provides a mixture of 25 to 55% by weight of lightweight inorganic materials, 20 to 44% by weight of inorganic binder, 5 to 22% by weight of hardener and filler, 0.2 to 1.5% by weight of water repellent, and 5 to 25% by weight of water. The non-combustible heat-resistant panel using the clay minerals are prepared.
또한, 경량무기물과 경화제 및 충전제를 먼저 혼합하고 무기점결제, 발수제 및 물을 혼합한 다음, 이 두 혼합물을 함께 균질한 조성이 되도록 혼합하고, 상기 혼합물을 50~150kg/cm2 의 성형압력으로 성형한후 최고 150℃의 온도로 건조시켜 내열판넬을 제조하는 점토류 광물을 이용한 불연성 내열판넬의 제조방법이 제공된다.In addition, firstly, the light inorganic material, the curing agent and the filler are mixed, the inorganic binder, the water repellent, and the water are mixed together, and then the two mixtures are mixed together to be a homogeneous composition, and the mixture is molded at a molding pressure of 50 to 150 kg / cm 2 . Thereafter, a method of manufacturing a non-flammable heat resistant panel using clay minerals which is dried to a temperature of up to 150 ° C. to produce a heat resistant panel is provided.
이하, 본 발명에 따른 불연성 내열판넬및 그 제조방법을 설명한다. Hereinafter, a non-flammable heat resistant panel and a method of manufacturing the same according to the present invention.
본 발명의 내열판넬은, 경량무기물 25∼55 중량%, 무기점결제 20∼44 중량%, 경화제 및 충전제 5∼22 중량%, 발수제 0.2∼1.5 중량% 그리고 물 5∼25 중량%가 혼합되어 조성된다. The heat-resistant panel of the present invention is composed of 25 to 55% by weight of lightweight inorganic materials, 20 to 44% by weight of inorganic binders, 5 to 22% by weight of hardeners and fillers, 0.2 to 1.5% by weight of water repellents and 5 to 25% by weight of water. .
또한, 필요에 따라서 무기물로 이루어진 착색제와 충전제가 더 혼합되어 이루어질 수 있다.In addition, if necessary, a colorant made of an inorganic material and a filler may be further mixed.
상기 경량무기물은, 퍼라이트, 시라스발룬, 질석 및 유리발룬, 발포유리, 팽창흑연 등이 있으며, 이와같은 재료를 판넬의 주성분으로 하여 판넬자체의 중량을 감소시킴은 물론 균열등의 결함을 방지하고, 불연성, 내열성 및 방음성을 발휘하게 된다. The lightweight inorganic materials, such as perlite, shiras balun, vermiculite and glass balun, foamed glass, expanded graphite, etc., as the main component of the panel to reduce the weight of the panel itself, as well as to prevent defects such as cracks, It exhibits incombustibility, heat resistance and sound insulation.
입자크기는 0.1~5mm의 범위가 적당하며 그 첨가량이 25 중량% 미만이면 이와같은 물성이 잘 발휘되지 않고 55중량%를 초과해서 첨가시에는 판넬의 비중은 낮아지지만 강도가 저하되는 현상이 나타날 수 있다.If the particle size is in the range of 0.1 ~ 5mm, the added amount is less than 25% by weight, and this property is not exhibited well, and when it is added in excess of 55% by weight, the specific gravity of the panel is lowered but the strength may be decreased. have.
상기 무기점결제로서는 알카리금속규산염을 지칭하며, 알카리금속은 나트륨과 칼륨을 포함하는 군중 선택된 어느 하나이고, 상기 알카리금속은 규산나트륨과 규산칼륨이 적당하며, 상기 규산나트륨의 경우 몰비(SiO2/Na2O의 몰비)가 3.0~3.5이고 액상이어야 한다.The inorganic binder refers to an alkali metal silicate, wherein the alkali metal is any one selected from the group consisting of sodium and potassium, and the alkali metal is preferably sodium silicate and potassium silicate, and in the case of sodium silicate (MoO 2 / Na Molar ratio of 2 O) should be 3.0-3.5 and liquid.
상기 경화제 및 충전제는 국내에 매장량이 풍부한 광물로써 고령토, 점토및 황토 등을 나타내며 고령토의 경우 저품질의 것을 사용해도 무방하다. The hardeners and fillers represent kaolin, clay and loess as minerals abundant in Korea, and in the case of kaolin, low quality ones may be used.
이들 광물의 크기는 약 0.1mm 이하의 것이 적당하며 입자크기가 더 조대하면 점결제의 양이 적게 소모되지만 성형후 파괴위험성이 있어서 좋지 않다. It is appropriate that these minerals are about 0.1 mm or less in size and coarse particle sizes consume less amount of binder, but are not good because of the risk of fracture after molding.
그리고, 상기 경화제및 충전제는 5 중량% 미만으로 첨가하거나 22 중량%를 초과해서 첨가시, 판넬의 강도 부족현상이 나타날 수 있거나 백화현상이 발생할 수도 있다.When the curing agent and the filler are added in an amount of less than 5 wt% or in an amount of more than 22 wt%, the strength of the panel may be insufficient or whitening may occur.
더하여 상기 발수제는, 무기점결제 사용시 발생할 수 있는 내흡습성과 내수성의 불충분 현상을 보완하는 역할을 수행하는 것으로서, 내흡습성과 내수성이 부족하게 되면 대기중의 습기나 물이 판넬과 접촉시 판넬의 강도 열화현상이 나타나게 된다. In addition, the water-repellent agent serves to compensate for insufficient phenomena of hygroscopicity and water resistance, which may occur when the inorganic binder is used, and when the moisture resistance and water resistance become insufficient, the moisture of the air deteriorates the panel when it comes into contact with the panel. The phenomenon appears.
상기 발수제의 첨가량은 0.2~1.5 중량%가 적당하며 이 범위를 벗어나게 되면 발수효과가 충분히 나타나지 않거나 발수제 첨가량이 쓸데없이 과도하게 되어 불필요한 낭비의 요인이 될 수 있다.The addition amount of the water repellent is 0.2 ~ 1.5% by weight is suitable, if out of this range does not appear sufficiently water repellent effect or excessively excessive amount of water repellent may be a waste of unnecessary waste.
마지막으로, 상기 물은 무기점결제의 점도 조절용으로 5~25 중량%를 첨가하며 점결제의 점도가 크면 조성물의 균질혼합이 이루어지지 않기 때문에 첨가하는 것으로서, 따라서 하절기에는 하한부근의 양을, 동절기에는 상한부근의 양을 첨가한다. Finally, the water is added to 5 to 25% by weight for adjusting the viscosity of the inorganic binder, and if the viscosity of the binder is high because the homogeneous mixing of the composition is not added, therefore, the amount near the lower limit in the summer season, Add the amount near the upper limit.
그리고, 상기 물 첨가량이 과도하게 되면 혼합이 잘 되지만 성형시 액상이 유출되어서 작업에 지장이 있게 되며 건조경화시 에너지 낭비요인이 된다.In addition, when the amount of the water is excessively mixed well, but the liquid phase during the molding flows out of the operation and becomes a waste of energy during drying and curing.

먼저, 경량무기물과 경화제 및 충전제를 먼저 혼합하고 무기점결제, 발수제 및 물을 혼합한 다음, 이 두 혼합물을 함께 균질한 조성이 되도록 혼합한다.First, the light inorganics, the curing agent and the filler are first mixed, the inorganic binder, the water repellent, and the water are mixed, and then the two mixtures are mixed together to have a homogeneous composition.
상기에서 혼합물을 이루는 각 구성물은 경량무기물 25∼55 중량%, 무기점결제 20∼44 중량%, 경화제 및 충전제 5∼22 중량%, 발수제 0.2∼1.5 중량% 그리고 물 5∼25 중량%가 투입되어 혼합된다.Each component constituting the mixture is mixed with 25 to 55% by weight of lightweight inorganic materials, 20 to 44% by weight of inorganic binders, 5 to 22% by weight of hardeners and fillers, 0.2 to 1.5% by weight of water repellents and 5 to 25% by weight of water. do.
이때, 상기 경량무기물과 경화제 및 충전제는 먼저 혼합하고, 이어서 무기점결제, 발수제 및 물은 혼합하며, 이 두 혼합물이 균질한 조성이 되도록 혼합한다.At this time, the lightweight inorganic material, the curing agent and the filler are mixed first, and then the inorganic binder, the water repellent, and the water are mixed, and the two mixtures are mixed to have a homogeneous composition.
그리고, 상기와 같은 혼합물을 성형하기 위하여 제품 성형을 위한 형상을 갖는 금형에 주입하여 50~150kg/cm2 의 성형압력을 가하여 성형한다.Then, in order to mold the mixture as described above is injected into a mold having a shape for forming a product is molded by applying a molding pressure of 50 ~ 150kg / cm 2 .
계속하여, 성형된 제품은 건조로에서 최고 약 150℃로 건조하여 수분을 증발시켜서 충분히 경화시킨다. Subsequently, the molded product is dried to a maximum of about 150 ° C. in a drying furnace to evaporate the moisture to sufficiently cure.
이때, 상술한 압력 성형단계와 건조경화공정은 독립적으로 또는 동시에 수행될 수 있다.At this time, the above-mentioned pressure forming step and the dry curing process may be performed independently or simultaneously.
이하, 본 발명에 따른 불연성 내열판넬의 실시예를 통하여 그 구성과 작용을 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the non-flammable heat resistant panel according to the present invention will be described in detail.
[실시예 1]Example 1
질석 22 중량%, 퍼라이트 15 중량%와 -50㎛이하의 입도를 가진 점토 20 중량%를 먼저 혼합하고 몰비가 3.2인 규산나트륨 35 중량%에 물 7.5중량%와 발수제 0.5 중량%를 첨가하여 혼합한 다음 이 두 혼합물을 다시 균질 혼합시켰다. 22% by weight vermiculite, 15% by weight of perlite and 20% by weight of clay having a particle size of less than -50㎛ are mixed first, and then 35% by weight of sodium silicate having a molar ratio of 3.2 is added by mixing 7.5% by weight of water and 0.5% by weight of water repellent. These two mixtures were then homogeneously mixed again.
이 혼합물을 금형에 주입하여 약 100kg/㎠의 압력으로 압축, 발형하여 두께가 약 20mm인 판재를 성형하였다. The mixture was injected into a mold, pressed and molded at a pressure of about 100 kg / cm 2 to form a plate having a thickness of about 20 mm.
성형된 판넬은 약 50℃로 1시간, 그리고 약 150℃로 역시 1시간 건조시켜서 경화시켰다.The molded panel was cured by drying at about 50 ° C. for 1 hour and also at about 150 ° C. for 1 hour.
