본 발명은 글라스 울이나 미네랄 울을 소재로 하여 제조된 단열 판넬에 관한 것이다.The present invention relates to an insulating panel made of glass wool or mineral wool.
글라스 울 또는 미네랄 울을 소재로 한 단열 시이트(sheet) 또는 단열 매트(mat)는 일반적으로 유리 원료 또는 미네랄 원료를 고열로 액화시켜 고속 회전 원심공법에 의해 제조한다. An insulating sheet or mat made of glass wool or mineral wool is generally manufactured by liquefying a glass material or a mineral material at high temperature and using a high-speed rotary centrifugal method.
도 1은 유리 원료 또는 미네랄 원료를 고열로 액화시켜 고속 회전 원심공법에 의해 형성된 종래의 원통형 중간재를 도시한다. 고속 회전 원심공법은 화이버(fiber)가 원통형으로 적층되면서 원통형 중간재를 제조하는 공지된 기술이다. 원통형 중간재는 직경이 약 700∼800mm이고, 적층된 화이버의 두께가 약 80∼150mm이다. 원통형 중간재를 A-A’선을 따라 절개하고, 양 측단을 절단하면, 도 2와 같은 시이트(sheet) 또는 매트(mat) 형상의 단열재가 형성된다. 양 측단이 절단된 시이트(매트)의 폭은 대략 2,000mm이다.1 shows a conventional cylindrical intermediate material formed by a high-speed rotary centrifugal method by liquefying a glass material or a mineral material at high temperature. The high-speed rotational centrifugal method is a known technology for producing a cylindrical intermediate member while fibers are stacked in a cylindrical shape. The cylindrical intermediate member has a diameter of about 700 to 800 mm, and the laminated fibers have a thickness of about 80 to 150 mm. When the cylindrical intermediate material is cut along the line A-A' and both side ends are cut, a sheet or mat-shaped heat insulator as shown in FIG. 2 is formed. The width of the sheet (mat) from which both side ends are cut is approximately 2,000 mm.
그런데, 도 2의 단열재는 화이버가 시이트(또는 매트)의 수평 방향으로 배열되기 때문에, 압축강도나 휨강도가 매우 약하다. 따라서, 도 2에 도시된 바와 같이, B-B’선과 같이 일정한 간격으로 절단한 후, 절단된 소재를 90도 회전시켜 연속적으로 접착시킨다.However, since the fibers of the insulator of FIG. 2 are arranged in the horizontal direction of the sheet (or mat), the compressive strength or bending strength is very weak. Therefore, as shown in FIG. 2, after cutting at regular intervals like the line BB', the cut material is rotated 90 degrees and continuously bonded.
도 3은 절단된 소재를 90도 회전시켜 연속적으로 접착시킨 단열 판넬의 개략적인 사시도이다. 도 3의 단열 판넬은 화이버가 판넬의 수직 방향으로 배열된다. 도 3의 단열 판넬은 화이버가 판넬의 수직 방향으로 배열되기 때문에, 화이버가 시이트(또는 매트)의 수평 방향으로 배열된 도 2의 시이트에 비해 압축강도가 약 4배 정도 증가한다. 글라스 울 또는 미네랄 울을 소재로 단열 판넬에서, 압축강도나 휨강도를 향상시키고자 하는 경우에는 도 1 내지 도 3에 도시된 방법에 따라 단열 판넬을 제조한다.3 is a schematic perspective view of a heat insulation panel in which cut materials are continuously bonded by rotating them by 90 degrees. In the insulation panel of FIG. 3 , fibers are arranged in a vertical direction of the panel. Since the fibers of the insulation panel of FIG. 3 are arranged in the vertical direction of the panel, the compressive strength is increased by about 4 times compared to the sheet of FIG. 2 in which the fibers are arranged in the horizontal direction of the sheet (or mat). When compressive strength or flexural strength of an insulating panel made of glass wool or mineral wool is to be improved, the insulating panel is manufactured according to the method shown in FIGS. 1 to 3 .
특허공개 제2007-0072640호는 글라스 울로 제조된 건축용 단열 판넬에 관한 것으로, 매트 상에서 글라스 울에 다수의 구멍을 배열 형성하고, 그것을 만들고자 하는 판넬의 두께로 절단하여, 상기 구멍이 판넬에 수평으로 형성되도록 90도 회전시켜 연속적으로 접합한 단열 판넬을 개시한다. 이렇게 함으로써, 구조적으로 튼튼하면서 무게를 감소시키고 단열성을 증가시킨 단열 판넬을 제공한다.Patent Publication No. 2007-0072640 relates to an insulating panel for construction made of glass wool, in which a plurality of holes are arranged in the glass wool on a mat, cut into the thickness of the panel to be made, and the holes are formed horizontally on the panel Rotate it 90 degrees as much as possible and start the continuously bonded insulation panels. By doing this, an insulating panel having reduced weight and increased insulating properties while being structurally strong is provided.
상기 설명한 종래의 방법에 의해 제조된 단열 판넬이나 특허공개 제2007-0072640호에 개시된 단열 판넬은 화이버가 판넬의 수직 방향으로 배열되기 때문에, 강도는 향상되지만, 열전도가 화이버가 판넬의 수평 방향으로 배열된 것과 비교할 때 훨씬 더 빠르게 일어난다. The insulation panel manufactured by the conventional method described above or the insulation panel disclosed in Patent Publication No. 2007-0072640 has improved strength because the fibers are arranged in the vertical direction of the panel, but the heat conduction is improved because the fibers are arranged in the horizontal direction of the panel. Compared to what happened, it happens much faster.
상기 설명한 바와 같이, 시이트(또는 매트)를 일정한 간격으로 절단한 후, 절단된 소재를 90도 회전시켜 연속적으로 접착시켜 압축강도나 휨강도를 향상시킨 종래의 단열 판넬은 제조 과정이 복잡하고, 그 결과 제조원가 상승을 초래한다. 또한 종래의 단열 판넬은 화이버가 판넬의 수평 방향과 직각인 수직 방향으로 배열되기 때문에, 열전도율이 큰 문제가 있다.As described above, after cutting the sheet (or mat) at regular intervals, the cut material is rotated 90 degrees and continuously bonded to improve the compressive strength or flexural strength, the conventional insulation panel has a complicated manufacturing process, and as a result cause an increase in manufacturing cost. In addition, since the fibers are arranged in a vertical direction perpendicular to the horizontal direction of the panel, the conventional insulation panel has a problem of high thermal conductivity.

본 발명의 목적은 800∼1,100℃ 정도의 고온에서 연소되지 않는 불연성을 갖는 새로운 단열 판넬을 제공하기 위한 것이다.An object of the present invention is to provide a new insulation panel having non-flammability that does not burn at a high temperature of about 800 to 1,100 ° C.
본 발명의 다른 목적은 무기질 시이트(또는 매트)를 일정한 간격으로 절단하여 90도 회전시켜 연속적으로 접착시키는 종래의 공정을 수행하지 않고, 시이트 그대로를 본 발명의 조성물로 처리하여 불연성을 갖는 단열 판넬을 제공하기 위한 것이다.Another object of the present invention is to provide a heat insulating panel having incombustibility by treating the sheet as it is with the composition of the present invention, without performing the conventional process of continuously bonding inorganic sheets (or mats) by cutting them at regular intervals and rotating them 90 degrees. is to provide
본 발명의 또다른 목적은 우수한 압축강도나 휨강도를 갖는 단열 판넬을 제공하기 위한 것이다.Another object of the present invention is to provide an insulating panel having excellent compressive strength or bending strength.
본 발명의 또다른 목적은 무기질 섬유(화이버)가 판넬의 수평 방향으로 배열되어 열전도율이 낮은 단열 판넬을 제공하기 위한 것이다.Another object of the present invention is to provide a heat insulation panel having low thermal conductivity in which inorganic fibers (fibers) are arranged in the horizontal direction of the panel.
본 발명의 또다른 목적은 무기질 시이트(또는 매트)를 절단하거나 접합하는 공정을 행하지 않음으로써 제조 원가를 절감할 수 있는 단열 판넬을 제공하기 위한 것이다.Another object of the present invention is to provide a heat insulation panel capable of reducing manufacturing costs by not performing a process of cutting or bonding inorganic sheets (or mats).
본 발명의 상기 및 기타의 목적들은 하기 상세히 설명되는 본 발명에 의하여 모두 달성될 수 있다.The above and other objects of the present invention can all be achieved by the present invention described in detail below.
본 발명의 단열 판넬은 고속 회전 원심공법에 의해 제조된 무기질 시이트(또는 매트)를 본 발명의 실란 조성액에 함침시켜서 제조한다. 상기 무기질 시이트의 소재는 글라스 울 또는 미네랄 울이다.The insulating panel of the present invention is manufactured by impregnating an inorganic sheet (or mat) manufactured by a high-speed centrifugal method with the silane composition solution of the present invention. The material of the inorganic sheet is glass wool or mineral wool.
무기질 시이트를 함침시키는 본 발명의 실란 조성액은 실란 화합물 100중량부당 물 40∼400중량부 및 설탕 20∼800중량부를 포함하고, 물과 설탕이 1:0.5 내지 1:2 범위인 것을 특징으로 한다.The silane composition liquid of the present invention for impregnating the inorganic sheet contains 40 to 400 parts by weight of water and 20 to 800 parts by weight of sugar per 100 parts by weight of the silane compound, and is characterized in that the ratio of water and sugar is in the range of 1:0.5 to 1:2.
무기질 시이트를 실란 조성액에 함침시키면, 무기질 시이트가 실란 조성액을 함유하게 된다. 100g의 시이트를 실란 조성액에 함침시키면 중량이 약 400∼500g으로 증가한다. 시이트 100g당 300∼400g의 실란 조성액이 함유되는 것이다.When the inorganic sheet is impregnated with the silane composition liquid, the inorganic sheet contains the silane composition liquid. When 100 g of the sheet is impregnated with the silane composition liquid, the weight increases to about 400 to 500 g. 300 to 400 g of the silane composition liquid is contained per 100 g of the sheet.
함침되었던 무기질 시이트는 과량의 실란 조성액을 함유하기 때문에 시이트를 짜서(squeezing) 과량의 조성액을 탈액해야 한다. 100g의 시이트에 실란 조성액이 함침된 시이트를 프레스(압착기)에 통과시켜 압착하면 중량이 약 200∼250g이 된다.Since the impregnated inorganic sheet contains an excess of the silane composition liquid, the excess composition liquid must be removed by squeezing the sheet. When a 100 g sheet impregnated with a silane composition liquid is passed through a press and compressed, the weight becomes about 200 to 250 g.
상기 탈액된 무기질 시이트를 건조시키면 본 발명의 단열 판넬이 완성된다. 100g의 무기질 시이트로 제조된 단열 판넬은 중량이 약 150∼200g이 된다.When the deliquid inorganic sheet is dried, the insulation panel of the present invention is completed. An insulating panel made of 100 g of inorganic sheet will have a weight of about 150 to 200 g.
본 발명의 단열 판넬은 무기질 시이트가 실란 조성액의 실란 화합물 및 설탕과 결합하여 견고하게 고화(固化)되기 때문에 견고한 강도를 갖는다. 즉, 본 발명의 단열 판넬은 압축강도와 휨강도가 우수하여 견고한 형태성을 갖고 취급이 용이하다. 무기질 시이트와 실란 조성액이 견고하게 결합하여 800∼1,100℃ 정도의 고온에서 연소되지 않는 불연성을 갖는다. 또한, 무기질 화이버가 판넬의 수평 방향으로 배열되기 때문에, 화이버가 판넬의 수직 방향으로 배열되는 종래의 판넬에 비해 열전도가 매우 낮은 장점이 있다. The insulating panel of the present invention has solid strength because the inorganic sheet is firmly solidified by combining with the silane compound and sugar in the silane composition liquid. That is, the insulated panel of the present invention has excellent compressive strength and bending strength, so it has a solid form and is easy to handle. The inorganic sheet and the silane composition liquid are firmly bonded to have non-combustible properties that do not burn at high temperatures of about 800 to 1,100°C. In addition, since the inorganic fibers are arranged in the horizontal direction of the panel, the thermal conductivity is very low compared to the conventional panel in which the fibers are arranged in the vertical direction of the panel.
이하 첨부된 도면을 참고로 본 발명의 구체적인 내용을 하기에 상세히 설명한다.Hereinafter, the specific contents of the present invention will be described in detail with reference to the accompanying drawings.

It has incombustibility that does not burn in, has excellent compressive strength or bending strength, and has the effect of the invention of providing a heat insulating panel in which inorganic fibers (fibers) are arranged in the horizontal direction of the panel and have low thermal conductivity. In addition, the present invention provides a heat insulating panel and a method for manufacturing the same, which can reduce manufacturing costs by not cutting or bonding inorganic sheets (or mats).

글라스 울 또는 미네랄 울을 소재로 한 단열 시이트(또는 매트)는 일반적으로 유리 원료 또는 미네랄 원료를 고열로 액화시켜 고속 회전 원심공법에 의해 제조한다. 도 1은 유리 원료 또는 미네랄 원료를 고열로 액화시켜 고속 회전 원심공법에 의해 글라스 울 또는 미네랄 울 시이트를 제조하기 위한 원통형 중간재를 개략적으로 도시한다. 고속 회전 원심공법에 의해 화이버가 원통형으로 적층되면서 원통형 중간재가 제조되고, A-A’선을 따라 절개하여 도 2와 같은 무기질 시이트를 형성한다. 도 2의 시이트를 B-B’선과 같이 일정한 간격으로 절단한 후, 절단된 소재를 90도 회전시켜 연속적으로 접착시킨다. 도 3은 도 2에 도시된 시이트를 B-B’선에 따라 일정한 간격으로 절단한 후, 절단된 소재를 90도 회전시켜 연속적으로 접착시켜 압축강도를 향상시킨 종래의 단열 판넬의 개략적인 사시도이다. 도 3의 단열 판넬은 화이버가 판넬의 수직 방향으로 배열되기 때문에, 화이버가 시이트(또는 매트)의 수평 방향으로 배열된 도 2의 시이트에 비해 압축강도가 약 4배 정도 증가한다. 하지만, 종래의 단열 판넬은 화이버가 판넬의 수평 방향과 직각인 수직 방향으로 배열되기 때문에, 열전도율이 큰 문제가 있다.An insulating sheet (or mat) made of glass wool or mineral wool is generally manufactured by a high-speed rotational centrifugal method by liquefying a glass material or a mineral material at high temperature. 1 schematically shows a cylindrical intermediate material for producing a glass wool or mineral wool sheet by liquefying a glass raw material or a mineral raw material at high temperature and using a high-speed rotary centrifugal method. As the fibers are stacked in a cylindrical shape by the high-speed rotation centrifugal method, a cylindrical intermediate material is manufactured, and an inorganic sheet as shown in FIG. 2 is formed by cutting along the line A-A'. After cutting the sheet of FIG. 2 at regular intervals as shown in the line BB', the cut material is rotated 90 degrees and continuously bonded. 3 is a schematic perspective view of a conventional insulation panel in which the sheet shown in FIG. 2 is cut at regular intervals along the line BB', and then the cut material is rotated 90 degrees and continuously bonded to improve the compressive strength. . Since the fibers of the insulation panel of FIG. 3 are arranged in the vertical direction of the panel, the compressive strength is increased by about 4 times compared to the sheet of FIG. 2 in which the fibers are arranged in the horizontal direction of the sheet (or mat). However, since the fibers are arranged in a vertical direction perpendicular to the horizontal direction of the panel, the conventional insulation panel has a problem of high thermal conductivity.

본 발명의 단열 판넬은 고속 회전 원심공법에 의해 제조된 무기질 시이트(또는 매트)를 본 발명의 실란 조성액에 함침시켜서 제조한다. 상기 무기질 시이트의 소재는 글라스 울 또는 미네랄 울이다.The insulating panel of the present invention is manufactured by impregnating an inorganic sheet (or mat) manufactured by a high-speed centrifugal method with the silane composition solution of the present invention. The material of the inorganic sheet is glass wool or mineral wool.
무기질 시이트를 함침시키는 본 발명의 실란 조성액은 실란 화합물 100중량부당 물 40∼400중량부 및 설탕 20∼800중량부를 포함하고, 물과 설탕이 1:0.5 내지 1:2 범위인 것을 특징으로 한다.The silane composition liquid of the present invention for impregnating the inorganic sheet contains 40 to 400 parts by weight of water and 20 to 800 parts by weight of sugar per 100 parts by weight of the silane compound, and is characterized in that the ratio of water and sugar is in the range of 1:0.5 to 1:2.
실란 화합물은 100중량부당 0.1∼2.0중량부의 초산, 염산 또는 황산이 부가된 화합물이다. 실란 화합물로는 메틸트리메톡시실란(CH3-Si-(OCH3)3), 메틸트리에톡시실란(CH3-Si-(OCH2CH3)3), 테트라에톡시실란(Si-(OC2H5)4), 글리시독시프로필트리메톡시실란(CH2(O)CHCH2OC3H6-Si-(OCH3)3), 메타크릴옥시프로필트리메톡시실란(H2C=CH(CH3)C(O)OC3H6-Si-(OCH3)3), 및 비닐트리메톡시실란(H2C=CH-Si-(OCH3)3)으로 이루어진 군으로부터 선택된다. 메틸트리메톡시실란(MTMS)이 바람직하게 사용될 수 있다. MTMS는 다우 코닝사의 XIAMETER(등록상표) OFS-6070 실란으로 시판되고 있다.The silane compound is a compound to which 0.1 to 2.0 parts by weight of acetic acid, hydrochloric acid or sulfuric acid is added per 100 parts by weight.

무기질 시이트를 실란 조성액에 함침시키면, 무기질 시이트가 실란 조성액을 함유하게 된다. 100g의 시이트를 실란 조성액에 함침시키면 중량이 약 400∼500g으로 증가한다. 시이트 100g당 300∼400g의 실란 조성액이 함유되는 것이다.When the inorganic sheet is impregnated with the silane composition liquid, the inorganic sheet contains the silane composition liquid. When 100 g of the sheet is impregnated with the silane composition liquid, the weight increases to about 400 to 500 g. 300 to 400 g of the silane composition liquid is contained per 100 g of the sheet.
함침되었던 무기질 시이트는 과량의 실란 조성액을 함유하기 때문에 시이트를 짜서(squeezing) 과량의 조성액을 탈액해야 한다. 과량의 조성액을 탈액하는 공정은 실란 조성액이 함침된 시이트를 프레스(압착기)에 통과시켜 탈액하는 공정으로 본 발명이 속한 기술분야의 당업자에 의해 용이하게 실시될 수 있다. 100g의 시이트에 실란 조성액이 함침된 시이트를 프레스(압착기)에 통과시켜 압착하면 중량이 약 200∼250g이 된다.Since the impregnated inorganic sheet contains an excess of the silane composition liquid, the excess composition liquid must be removed by squeezing the sheet. The process of deliquidating the excess composition liquid is a process of dehydrating the sheet impregnated with the silane composition liquid by passing it through a press (compressor), and can be easily performed by a person skilled in the art to which the present invention belongs. When a 100 g sheet impregnated with a silane composition liquid is passed through a press and compressed, the weight becomes about 200 to 250 g.
상기 탈액된 무기질 시이트를 건조시키면 본 발명의 단열 판넬이 완성된다. 100g의 무기질 시이트로 제조된 단열 판넬은 중량이 약 150∼200g이 된다. 건조 공정은 자연 건조도 가능하지만, 대량 생산을 위해 건조로를 사용할 수 있다.When the deliquid inorganic sheet is dried, the insulation panel of the present invention is completed. An insulating panel made of 100 g of inorganic sheet will have a weight of about 150 to 200 g. Natural drying is also possible for the drying process, but a drying furnace can be used for mass production.
본 발명의 단열 판넬은 무기질 시이트가 실란 조성액의 실란 화합물 및 설탕과 결합하여 견고하게 고화(固化)되기 때문에 견고한 강도를 갖는다. 즉, 본 발명의 단열 판넬은 압축강도와 휨강도가 우수하여 견고한 형태성을 갖고 취급이 용이하다. 강도는 실란 조성액에 사용되는 물의 양으로 조절한다. 물의 사용량이 증가할수록 판넬의 강도는 약해지고, 물의 사용량이 감소할수록 판넬의 강도는 강해진다. 물의 사용량에 의한 판넬의 강도는 본 발명이 속한 기술분야의 당업자에 의해 용이하게 실시될 수 있다. 실란 조성액에 함유되는 설탕은 물과 대비하여 1:0.5 내지 1:2 범위로 사용되는데, 이는 물에 용해되는 설탕의 양을 고려한 것이다.The insulating panel of the present invention has solid strength because the inorganic sheet is firmly solidified by combining with the silane compound and sugar in the silane composition liquid. That is, the insulated panel of the present invention has excellent compressive strength and bending strength, so it has a solid form and is easy to handle. Strength is controlled by the amount of water used in the silane composition liquid. As the amount of water used increases, the strength of the panel weakens, and as the amount of water used decreases, the strength of the panel increases. The strength of the panel by the amount of water used can be easily performed by a person skilled in the art to which the present invention belongs. The sugar contained in the silane composition liquid is used in the range of 1:0.5 to 1:2 compared to water, which takes into account the amount of sugar dissolved in water.
무기질 시이트와 실란 조성액이 견고하게 결합하여 800∼1,100℃ 정도의 고온에서 연소되지 않는 불연성을 갖는다. 또한, 무기질 화이버가 판넬의 수평 방향으로 배열되기 때문에, 화이버가 판넬의 수직 방향으로 배열되는 종래의 판넬에 비해 열전도가 매우 낮다.The inorganic sheet and the silane composition liquid are firmly bonded to have non-combustible properties that do not burn at high temperatures of about 800 to 1,100°C. In addition, since the inorganic fibers are arranged in the horizontal direction of the panel, the heat conduction is very low compared to conventional panels in which the fibers are arranged in the vertical direction of the panel.
본 발명은 하기 실시예에 의해 보다 구체화될 것이며, 하기 실시예는 본 발명의 예시 목적으로 제시될 뿐, 본 발명의 보호범위를 한정하거나 제한하고자 하는 것이 아니다. The present invention will be further specified by the following examples, which are presented for illustrative purposes only and are not intended to limit or limit the scope of the present invention.
실시예 1-4 및 비교실시예 1-2: 실란 조성액의 조성 및 측정 결과Example 1-4 and Comparative Example 1-2: Composition and measurement results of silane composition solution
표 1에 나타난 조성에 따라 실시예 1-4 및 비교실시예 1-2의 실란 조성액을 제조하였다. 실란 화합물로는 다우 코닝사의 XIAMETER(등록상표) OFS-6070 실란인 메틸트리메톡시실란(CH3-Si-(OCH3)3)을 사용하였다. 상기 실란 화합물에는 0.1중량부의 초산이 첨가되었다.The silane composition solutions of Examples 1-4 and Comparative Example 1-2 were prepared according to the compositions shown in Table 1. As the silane compound, Dow Corning's XIAMETER (registered trademark) OFS-6070 silane, methyltrimethoxysilane (CH 3 -Si-(OCH 3 ) 3 ) was used. 0.1 part by weight of acetic acid was added to the silane compound.
두께 100mm의 글라스 울 시이트를 표 1의 실란 조성액에 함침시킨 후, 꺼내서 프레스에 통과시켜 과량의 실란 조성액을 탈액한다. 상기 탈액된 시이트를 자연 건조하여 단열 판넬을 제조한다. 제조된 단열 판넬에 대해 용융온도와 압축강도를 측정하였다. After a glass wool sheet having a thickness of 100 mm was impregnated with the silane composition liquid of Table 1, it was taken out and passed through a press to remove excess silane composition liquid. The de-liquid sheet is naturally dried to manufacture an insulating panel. The melting temperature and compressive strength of the manufactured insulation panels were measured.
실시예 1-4의 실란 조성액으로 처리한 단열 판넬은 1,000℃ 이상의 용융온도를 나타내지만, 실란 화합물을 함유하지 않은 비교실시예 1-2의 설탕수용액으로 처리한 단열 판넬은 400℃ 이하의 용융온도를 나타내었다.Insulation panels treated with the silane composition solution of Example 1-4 exhibited a melting temperature of 1,000 ° C or more, but the insulation panels treated with the aqueous sugar solution of Comparative Example 1-2 containing no silane compound had a melting temperature of 400 ° C or less. showed
압축강도는 관능 테스트에 의한 것으로, 실시예 1-4의 실란 조성액으로 처리한 단열 판넬은 도 3에 도시된 종래의 화이버가 수직 배열된 단열 판넬과 같은 수준의 강도를 유지하여 압축되거나 휨현상이 없는 강도를 나타내지만, 실란 화합물이 없는 비교실시예 1-2의 설탕 수용액으로 처리한 단열 판넬은 압축되거나 휨현상이 발생하여 강도가 약함을 알 수 있다.Compressive strength is obtained by a sensory test, and the insulation panel treated with the silane composition solution of Examples 1-4 maintains the same level of strength as the conventional insulation panel in which the fibers are vertically arranged shown in FIG. 3 and is not compressed or bent. Although it exhibits strength, it can be seen that the strength of the insulation panel treated with the aqueous sugar solution of Comparative Example 1-2 without a silane compound is weak due to compression or bending.
