Description
본 발명은 단열재용 시멘트계 바탕조정재 조성물 및 이를 포함하는 단열재용 시멘트계 바탕조정재에 관한 것으로서, 기존 시멘트계 바탕조정재 보다 열전도성이 낮은 단열재용 시멘트계 바탕조정재 조성물 및 이를 포함하는 단열재용 시멘트계 바탕조정재에 관한 것이다.The present invention relates to a cement-based background conditioning material composition for an insulating material and a cement-based background conditioning material for an insulating material comprising the same, and to a cement-based background conditioning material composition for an insulating material having lower thermal conductivity than an existing cement-based background conditioning material, and a cement-based background conditioning material for an insulating material comprising the same.
일반적으로 습식 외단열 공법에서는 건물 외피를 둘러싼 단열재의 상부에 시멘트계 바탕조정재를 시공한 뒤 얇은 마감재를 상부에 미장하는 방식으로 마감 시공한다. In general, in the wet exterior insulation method, a cement-based base adjustment material is installed on the top of the insulation surrounding the building envelope, and then a thin finishing material is plastered on the top.
기존 시멘트계 바탕조정재는 무기물인 시멘트 성분의 함량이 높아 외부 기온이 상승함에 따라 표면의 온도가 상승하고, 열에너지가 누적되면서 구조물의 온도 상승을 유발하게 된다. 따라서, 구조물의 열적 성능을 개선하기 위한 시멘트계 바탕조정재가 요구되고 있다. Existing cement-based base conditioning materials have a high content of inorganic cement components, so the surface temperature rises as the external temperature rises, and thermal energy accumulates, causing the temperature of the structure to rise. Therefore, there is a demand for a cement-based base control material for improving the thermal performance of the structure.
한편, 제철 산업 부산물 중 페로니켈 슬래그는 마그네슘 함량이 약 24 ~ 40% 가량을 함유하고 있는 물질로서 텅스텐 제조 공정에서 발생되고 있다. 매년 약 10만톤 가량의 산업부산물이 발생되면서, 누적 산업부산물은 해마다 증가하는 추세에 있어 이의 처리 방안에 대한 연구가 절실한 상황이다. 페로니켈슬래그는 높은 마그네슘 함량으로 인해 열확산성이 크고, 열전도율이 낮은 특성을 지니고 있음에 따라 구조물의 표면에 누적되는 열량을 제어할 수 있는 소재로 기대될 수 있는 장점이 있다. On the other hand, ferronickel slag among the by-products of the ironmaking industry is a material containing about 24 to 40% of magnesium and is generated in the tungsten manufacturing process. As about 100,000 tons of industrial by-products are generated every year, the accumulated industrial by-products are increasing year by year, so research on treatment methods is urgently needed. Since ferronickel slag has high thermal diffusivity and low thermal conductivity due to its high magnesium content, it has the advantage that it can be expected as a material that can control the amount of heat accumulated on the surface of the structure.
국내 천연규사는 해사와 규석 광산에서 채취하는 인공 규사로 구분되어 생산되고 있다. 현재 규사 자원 중 순도가 높은 규석의 경우, 폴리실리콘의 원료와 같이 전자산업 소재로 주로 사용되고 있으며, 이외의 인공 규사는 특수 모르타르의 골재로 사용되고 있다. 인공 규사는 임야를 채굴하여 규석을 추출하는 공정을 거치게 됨에 따라 환경 파괴와 부산물로 발생되는 여러 문제점을 수반하고 있어 천연 규사의 사용량을 증가시키는 것이 중요한 시점이다. In Korea, natural silica sand is produced separately from sea sand and artificial silica sand collected from silicate mines. Currently, among the silica sand resources, high-purity silica is mainly used as a material for the electronics industry, such as a raw material for polysilicon, and artificial silica sand is used as an aggregate for special mortars. As artificial silica sand goes through the process of extracting silica by mining forest fields, it is accompanied by environmental destruction and various problems that occur as by-products, so it is important to increase the amount of natural silica sand used.
본 발명은 기존 시멘트계 바탕조정재 보다 산업부산물의 사용을 증진하여 천연규사의 사용량을 저감하고, 열환경성을 향상할 수 있는 시멘트계 바탕조정재 조성물 및 이를 포함하는 단열재용 시멘트계 바탕조정재를 제공하고자 한다.The present invention is to promote the use of industrial by-products compared to the existing cement-based background conditioning material, thereby reducing the amount of natural silica sand used, and to provide a cement-based background conditioning material composition capable of improving thermal environmental properties and a cement-based background conditioning material for insulation including the same.

The ferronickel manufacturing process is a dry manufacturing method developed by SLN of France from the 1890s and adopted and operated in Japan and Colombia. It is a method of manufacturing ferronickel by melting and reducing ore in an electric furnace. In the main process, ferronickel containing about 20% nickel and about 80% iron is produced. It is known that ferronickel slag generates about 6 tons of slag when producing 1 ton of ferronickel, and ferronickel slag is generated about 1 million tons per year and is chemically stable, so its potential to be used as a filler and concrete aggregate is quite high. When the ferronickel slag of the present invention is included as a ground control material, there is an advantage in that the concentration of heat can be reduced by easily diffusing the amount of heat present in the building envelope to the outside due to the high magnesium content in the ferronickel slag. In addition, the ferronikel slag of the present invention may be one obtained by slowly cooling a by-product during a tungsten production process in an ironworks and pulverizing and separating it to an appropriate particle size.

3) 온냉반복강도 측정(N/㎟)3) Measurement of heat and cold repetition strength (N/㎟)
제조된 단열재용 시멘트계 바탕조정재에 대해 KS F 4716규정에 의해 온냉반복강도를 측정하였다.For the manufactured cement-based background adjustment material for insulation, the strength of hot and cold repeated strength was measured according to KS F 4716.
4) 열환경성 평가4) Thermal environment evaluation
제조된 단열재용 시멘트계 바탕조정재에 대해 열환경성 평가를 진행하기 위해 30cm(가로) X 30cm(세로) X 30cm(높이)의 스티로폼 박스의 외부에 열환경 제어를 위해 제조된 시멘트계 바탕조정재를 표면에 도포한 뒤 건조하였다. 이 후, 스티로폼 박스 상부에 열센서를 설치한 뒤, 외기 노출시의 외피면의 최저온도 및 최고온도를 측정하였다.In order to conduct thermal environmental evaluation of the manufactured cement-based base adjuster for insulation, the cement-based base adjuster prepared for thermal environment control is applied to the outside of a 30cm (width) X 30cm (length) X 30cm (height) styrofoam box. and then dried. After that, a thermal sensor was installed on the upper part of the Styrofoam box, and the minimum and maximum temperatures of the outer surface when exposed to outdoor air were measured.
상기 표 4에서 확인할 수 있듯이, 실시예 1에서 제조된 단열재용 시멘트계 바탕조정재는 부착강도 및 온냉반복강도가 우수할 뿐만 아니라, 물흡수계수가 낮고, 열환경성 평가 또한 우수한 것을 확인할 수 있었다.As can be seen in Table 4, it was confirmed that the cement-based base control material for insulation prepared in Example 1 was excellent in adhesion strength and hot/cold repetition strength, as well as a low water absorption coefficient and excellent thermal environment evaluation.
