원적외선방사 온돌바닥재 및 그 제조방법Far Infrared Radiant Ondol Floor Material and Manufacturing Method Thereof
원적외선 방사율이 높은 마그네사이트계 광물을 적정온도에서 소성하면 적정한 선팽창율을 가지는 동시에 원적외선 방사효과를 극대화시킬 수 있다. 이 물질에 원적외선 방사율이 높은 물질을 배합하고 황산 마그네슘(MgSO4)을 적정량 투입하여 경화시키면 균열이 발생되지 않으면서도 원하는 압축강도를 발현시킬 수 있다. 본 발명은 이와 같은 원적외선방사 온돌바닥재 및 그 제조방법에 관한 것이다.When the magnesite mineral with high far-infrared emissivity is fired at an appropriate temperature, it has an appropriate linear expansion rate and maximizes the far-infrared radiation effect. When this material is mixed with a material having a high far-infrared emissivity and a suitable amount of magnesium sulfate (MgSO 4 ) is added and cured, the desired compressive strength can be expressed without cracking. The present invention relates to such a far-infrared radiation ondol flooring material and a method for producing the same.
현재, 생활경제가 발전하고 생활의 질적향상이 이루어짐에 따라 건강에 대한 관심이 고조되면서 주거문화에도 황토바닥재 등과 같은 원적외선 방사효과가 있는 바닥재 시공이 증가하는 추세이다. 상기 황토 등 원적외선 방사효과가 있는 물질을 사용한 바닥재는 원적외선의 열작용에 의해서 혈관운동을 자극하여 건강을 유지 향상시키는 효과를 가진다.Currently, as the economy of life develops and the quality of life is improved, interest in health is increasing, and the construction of flooring materials with far-infrared radiation effects such as ocher floor materials is increasing in residential culture.

본 발명에 사용되는 경소 마그네시아는 MgO성분이 55-93중량%인 것으로서 마그네사이트를 소성로에서 650-950℃로 소성하여 만들어지고 200Mesh 이하, 120Mesh 이하의 분말상으로 분쇄되어 용도에 적합하게 사용되는데, 그 양으로는 10-80중량%, 바람직하게는 10-60중량%가 사용된다.The light magnesia used in the present invention has a MgO component of 55-93% by weight and is made by firing magnesite at 650-950 ° C. in a kiln and is pulverized into powders of 200Mesh or less and 120Mesh or less, and the amount thereof is suitably used. 10-80% by weight, preferably 10-60% by weight is used.

본 발명에 사용되는 황산 마그네슘(MgSO4) 혹은 간수(MgCl2)는 경소 마그네시아(MgO)와 결합제로 사용되는 바, 이는 마그네시아(MgO)와 물(H2O)의 결합시 MgCO3로 되면서 반응열이 급격히 발생하여 바닥균열이 심하게 발생하는 현상을 유발하기 때문에, 황산 마그네슘의 적정량 투입은 mMgO·MgSO4·nH2O의 미세한 결정형성으로 유도되어 MgCO3결합을 억제시킴과 동시에 반응열을 하강시킬 수 있으며, 마그네시아의 전기전도도는 정전기 발생을 억제시킬 수 있다.Magnesium sulfate (MgSO 4 ) or brine (MgCl 2 ) used in the present invention is used as a binder with light magnesium (MgO), which becomes MgCO 3 when combined with magnesia (MgO) and water (H 2 O) Because of the rapid occurrence of this phenomenon, the bottom crack is severely induced, and an appropriate amount of magnesium sulfate may be induced by fine crystal formation of mMgO · MgSO 4 · nH 2 O to inhibit MgCO 3 binding and lower the reaction heat. In addition, the electrical conductivity of magnesia can suppress the generation of static electricity.
즉, 상기 황산마그네슘 혹은 간수는 감수제로서 MgO가 MgCO3로 수화반응을 억제시켜 경화시 균열을 방지하고 MgO와 결합하여 압축강도를 발현시키는 역할을 하며, 배합재료에 대해 MgO가 20-80중량%일 경우에 황산마그네슘 혹은 간수의 투입량은 3-20중량%가 사용된다.That is, the magnesium sulfate or the brine serves as a sensitizer to prevent the hydration reaction of MgO to MgCO 3 to prevent cracking during curing and to express compressive strength by combining with MgO, MgO 20-80% by weight relative to the blending material In one case, 3-20% by weight of magnesium sulfate or water is used.

표2 내지 표5에 나타난 바와 같이 본 발명은 원적외선방사 바닥재 고유의 건강증진기능을 극대화 할 수 있을 뿐만 아니라 종래 원적외선방사 바닥재의 시공상의 문제점인 균열발생, 강도저하 및 경화시간의 장기화 등을 해소할 수 있음을 알 수 있다.As shown in Tables 2 to 5, the present invention not only maximizes the health promotion function inherent to the far-infrared radiation flooring but also solves the problems of construction of the conventional far-infrared radiation flooring, cracking, strength reduction, and prolongation of curing time. It can be seen that.
이상 설명한 바와 같이 본 발명에 의하면, 원적외선 방사율이 높은 물질인 황토, 일라이트, 맥반석, 납석, 견운모와 마그네사이트를 사용하되, 종래와 같이 결합재로서 시멘트나 유기 접착제를 사용하지 않고 마그네사이트를 소성시켜 만든 마그네시아(MgO)를 사용하여 시멘트나 유기제의 유독성이 없으면서 원적외선 방사효과를 극대화할 수 있고 시공시 경화시간을 5-10시간으로 크게 단축할 수 있는 원적외선방사 온돌바닥재 및 그 제조방법을 제공할 수 있다.As described above, according to the present invention, magnesia is produced by calcining magnesite without using cement or organic adhesive as a bonding material, although ocher, illite, elvan, feldspar, mica and magnesite, which are materials having high far infrared emissivity, are used. By using (MgO) can provide far-infrared radiation ondol flooring material that can maximize the far-infrared radiation effect without significant toxicity of cement or organic agent and can greatly shorten the curing time during construction to 5-10 hours and its manufacturing method. .
또한, 배합재료에 황산마그네슘(MgSO4)은 혹은 간수(MgCl2) 적정량을 투입함으로써 경화시 마그네시아(MgO) 수화반응을 억제시켜 바닥균열이 발생되지 않으면서 상기 마그네시아(MgO)와 황산마그네슘(MgSO4)의 결합에 의해 우수한 압축강도를 발현시킬 수 있는 원적외선방사 온돌바닥재 및 그 제조방법을 제공할 수 있다.In addition, the amount of magnesium sulfate (MgSO 4 ) or mixed water (MgCl 2 ) is added to the blended material to inhibit the magnesia (MgO) hydration reaction during curing, so that the bottom crack does not occur and the magnesium sulfate (MgO) and magnesium sulfate (MgSO) The combination of 4 ) can provide a far-infrared radiation ondol flooring material capable of expressing excellent compressive strength and a method of manufacturing the same.
