Description
본 발명은 덕트 보온 커버에 관한 것으로, 보다 상세하게는 난연성이 우수한 덕트 보온 커버 및 그 제조 방법에 관한 것이다.
The present invention relates to a duct insulation cover, and more particularly to a duct insulation cover excellent in flame retardancy and a method of manufacturing the same.
덕트(duct) 보온을 위하여, 덕트에는 보온 커버가 부착되어 있다. 보온 커버는 통상 고무 발포 단열재층과 점착층으로 이루어진다. To keep the duct warmed, the duct is fitted with a thermal cover. The thermal insulation cover usually consists of a rubber foam insulation layer and an adhesive layer.
덕트 보온용 고무 발포 단열재는 니트릴 부타디엔 고무(Nitrile Butadiene Rubber) 발포 단열재(이하 NBR 고무 발포 단열재)와 에틸렌-프로필렌-디엔 모노머(Ethylene Propylene Diene (M-class) Monomer) 발포 단열재(이하, EPDM 고무 발포 단열재)가 주로 이용된다. Rubber foam insulation for duct insulation is Nitrile Butadiene Rubber foam insulation (hereinafter referred to as NBR rubber foam insulation) and ethylene-propylene-diene monomer (M-class) Monomer foam insulation (hereinafter referred to as EPDM rubber foam) Insulation) is mainly used.
EPDM 고무 발포 단열재는 가격이 저렴하면서도 단열성 및 내열성이 우수한 장점이 있다. 또한, NBR 고무 발포 단열재는 단열성 및 시공성이 우수하고 난연성이 뛰어난 장점이 있다. EPDM rubber foam insulation has the advantages of low cost but excellent heat insulation and heat resistance. In addition, NBR rubber foam insulation has the advantage of excellent heat insulation and workability and excellent flame retardancy.
그러나, 보온단열의 목적으로 덕트기구에 시공되는 고무 보온 커버 자재의 경우, 난연 성능이 좋지 못하다. 그 이유는 고무 발포 단열재 자체로 시공하기 보다는, 고무 발포 단열재 표면에 점착제를 가공하여 덕트 기구를 감싸서 보온 시공하는데, 이때 가공하는 제품 표면층에 일반적으로 사용되는 점착제의 난연성이 떨어지기 때문이다.
However, in the case of the rubber thermal insulation cover material which is constructed in the duct mechanism for the purpose of thermal insulation, the flame retardant performance is not good. The reason is that rather than constructing the rubber foam insulation itself, the adhesive is processed on the surface of the rubber foam insulation to wrap the duct mechanism to insulate the insulation, because the flame retardancy of the adhesive generally used in the surface layer of the product is inferior.
본 발명에 관련된 배경기술로는 대한민국 특허등록공보 10-1037383호(2011.05.26. 공고)가 있으며, 상기 문헌에는 고내열성 고무발포 단열재 및 그 제조 방법이 개시되어 있다.

On the other hand, the rubber foam insulation to form the rubber
상기 조성을 갖는 고무 발포 단열재는 고무 원료 100 중량부, 폴리테트라플루오르에틸렌 7~15중량부, 디아미노디페닐메탄 5~20중량부, 에폭시 수지 2~6중량부, 인산에스테르 1~4중량부, 산화 몰리브덴 3~7중량부, 벤조트리아졸 8~14중량부, 탈크 4~7중량부 및 발포제 1~20중량부를 포함하는 원료가 발포 등의 과정을 거쳐 제조될 수 있다. Rubber foam insulation having the above composition is 100 parts by weight of rubber raw material, 7 to 15 parts by weight of polytetrafluoroethylene, 5 to 20 parts by weight of diaminodiphenylmethane, 2 to 6 parts by weight of epoxy resin, 1 to 4 parts by weight of phosphate ester, Raw materials including 3 to 7 parts by weight of molybdenum oxide, 8 to 14 parts by weight of benzotriazole, 4 to 7 parts by weight of talc, and 1 to 20 parts by weight of a blowing agent may be prepared through a process such as foaming.
상기 조성을 갖는 원료로부터 제조된 고무 발포 단열재의 경우, 신율 : 500% 이상, 인장강도 : 80 Kgf/cm2 이상 및 한계 산소 지수(LOI) : 30 이상을 나타낼 수 있다. In the case of the rubber foam insulation prepared from the raw material having the composition, the elongation: 500% or more, the tensile strength: 80 Kgf / cm 2 or more and the limiting oxygen index (LOI): 30 or more can be shown.
이하, 상기 조성의 고무 발포 단열재의 각 성분에 대하여, 원료를 기준으로 그 역할 및 함량을 설명하기로 한다. Hereinafter, with respect to each component of the rubber foam insulation of the composition, its role and content based on the raw material will be described.
폴리테트라플루오르에틸렌 수지는 난연성 향상에 기여한다. 상기 폴리테트라플루오르에틸렌 수지는 고무 원료 100중량부에 대하여, 7~15중량부로 첨가되는 것이 바람직하다. 폴리테트라플루오르에틸렌 수지의 첨가량이 7 중량부 미만일 경우에는 난연성이 급격히 저하되는 것을 확인하였다. 반대로, 폴리테트라플루오르에틸렌 수지의 첨가량이 15중량부를 초과할 경우에는 열수축 현상이 발생하여 치수 정밀도가 저하되는 문제점이 있다.Polytetrafluoroethylene resins contribute to improved flame retardancy. It is preferable that the said polytetrafluoroethylene resin is added in 7-15 weight part with respect to 100 weight part of rubber raw materials. When the addition amount of polytetrafluoroethylene resin was less than 7 weight part, it was confirmed that flame retardance fell rapidly. On the contrary, when the addition amount of polytetrafluoroethylene resin exceeds 15 parts by weight, a heat shrinkage phenomenon occurs and there is a problem that the dimensional accuracy is lowered.
디아미노디페닐메탄은 고무 발포 단열재의 강도를 보완하는 역할을 한다. 상기 디아미노디페닐메탄은 고무 원료 100중량부에 대하여, 5~20중량부로 포함되는 것이 바람직하다. 디아미노디페닐메탄의 함량이 5중량부 미만인 경우, 그 첨가 효과가 불충분하다. 반면, 디아미노디페닐메탄의 함량이 20중량부를 초과할 경우에는 신율이 급격히 저하될 수 있다. Diaminodiphenylmethane serves to complement the strength of rubber foam insulation. It is preferable that the said diamino diphenylmethane is contained in 5-20 weight part with respect to 100 weight part of rubber raw materials. When the content of diaminodiphenylmethane is less than 5 parts by weight, the effect of addition thereof is insufficient. On the other hand, when the content of diaminodiphenylmethane exceeds 20 parts by weight, the elongation may be drastically lowered.
에폭시 수지는 고무 발포 단열재에 포함되는 각 성분의 결합력 향상과 함께 강도를 향상시키는 역할을 한다. 이러한 에폭시 수지는 공지된 에폭시 수지라면 제한없이 이용할 수 있으며, 보다 바람직하게는 2 이상의 에폭시기를 갖는 바이페닐계 에폭시 수지, 비스페놀계 에폭시 수지 등을 제시할 수 있다. 상기 에폭시 수지는 고무 원료 100중량부에 대하여, 2~6중량부로 첨가되는 것이 바람직하다. 에폭시 수지의 함량이 2중량부 미만일 경우, 그 첨가 효과가 불충분하다. 반대로, 에폭시 수지의 함량이 6중량부를 초과하는 경우, 신율이 급격히 저하될 수 있다. The epoxy resin plays a role of improving the strength together with improving the bonding strength of each component included in the rubber foam insulation. Such epoxy resin can be used without limitation if it is a well-known epoxy resin, More preferably, the biphenyl type epoxy resin, bisphenol type epoxy resin, etc. which have two or more epoxy groups can be presented. It is preferable that the said epoxy resin is added at 2-6 weight part with respect to 100 weight part of rubber raw materials. When the content of the epoxy resin is less than 2 parts by weight, the addition effect is insufficient. On the contrary, when the content of the epoxy resin exceeds 6 parts by weight, the elongation may be sharply lowered.
인산에스테르는 난연성 향상 및 분산성 향상에 기여한다. 이러한 인산에스테르는 고무 원료 100 중량부에 대하여 1~4중량부로 첨가되는 것이 바람직하다. 인산에스테르의 첨가량이 1중량부 미만일 경우, 그 첨가 효과가 불충분하다. 반대로, 인산에스테르의 첨가량이 4중량부를 초과하는 경우, 강도 등의 물성이 저하될 수 있다. Phosphate ester contributes to the improvement of flame retardancy and dispersibility. Such phosphate ester is preferably added in an amount of 1 to 4 parts by weight based on 100 parts by weight of the rubber raw material. When the addition amount of phosphate ester is less than 1 weight part, the addition effect is inadequate. On the contrary, when the addition amount of phosphate ester exceeds 4 weight part, physical properties, such as intensity | strength, may fall.
산화몰리브덴은 발포 단열재 자체의 난연성을 향상시키기 위한 목적으로 첨가된다. 상기 산화몰리브덴은 고무 원료 100 중량부에 대하여, 3~7중량부로 첨가되는 것이 바람직하다. 산화몰리브덴의 첨가량이 3중량부 미만일 경우에는 상기의 효과를 제대로 발휘할 수 없다. 반대로, 산화몰리브덴의 첨가량이 7중량부를 초과할 경우에는 더 이상의 첨가 효과 없이 신율 등의 물성을 저해할 수 있다. Molybdenum oxide is added for the purpose of improving the flame retardancy of the foam insulation itself. It is preferable that the said molybdenum oxide is added at 3-7 weight part with respect to 100 weight part of rubber raw materials. When the added amount of molybdenum oxide is less than 3 parts by weight, the above effects cannot be exerted properly. On the contrary, when the addition amount of molybdenum oxide exceeds 7 parts by weight, it is possible to inhibit physical properties such as elongation without further addition effect.
벤조트리아졸은 변색을 방지하기 위한 목적으로 첨가된다. 이러한 벤조트리아졸은 NBR 100 중량부에 대하여, 8~14중량부로 첨가되는 것이 바람직하다. 만일, 벤조트리아졸의 첨가량이 8중량부 미만으로 너무 적으면 가공성이 나빠지는 문제가 있다. 반대로, 벤조트리아졸의 첨가량이 14중량부를 초과하여 다량 첨가될 경우에는 벤조트리아졸로 인한 발포저하 현상이 발생하는 문제가 있다.Benzotriazole is added for the purpose of preventing discoloration. Such benzotriazole is preferably added in an amount of 8 to 14 parts by weight based on 100 parts by weight of NBR. If the amount of the benzotriazole added is less than 8 parts by weight, there is a problem of poor workability. On the contrary, when a large amount of benzotriazole is added in excess of 14 parts by weight, there is a problem in that foaming decrease due to benzotriazole occurs.
탈크(talc)는 무기 충전제로서, 내열성을 향상시키는 역할을 하며, 대략 3~6㎛의 평균입경을 갖는 것을 이용하는 것이 바람직하다. 상기 탈크는 NBR 100 중량부에 대하여 4~7중량부로 첨가되는 것이 바람직하다. 탈크의 첨가량이 4중량부 미만이면 그 첨가 효과가 불충분하고, 반대로, 탈크의 첨가량이 7중량부를 초과하는 경우, 신율 등의 물성이 저하될 수 있다. Talc is an inorganic filler, and serves to improve heat resistance, and it is preferable to use one having an average particle diameter of approximately 3 to 6 µm. The talc is preferably added in 4 to 7 parts by weight based on 100 parts by weight of NBR. If the addition amount of talc is less than 4 parts by weight, the effect of addition is insufficient. On the contrary, when the addition amount of talc exceeds 7 parts by weight, physical properties such as elongation may decrease.
또한, 고무 발포 단열재 혹은 그 원료는 아크릴아미드 화합물을 더 포함할 수 있다. 아크릴아미드 화합물을 첨가한 결과 다른 물성의 저하 없이 신율이 보다 향상되었다. In addition, the rubber foam insulation or its raw material may further contain an acrylamide compound. As a result of adding the acrylamide compound, the elongation was further improved without deteriorating other physical properties.
이러한 아크릴아미드 화합물은 (메타)크릴아미드, N-메틸(메타)크릴아미드, N-에틸(메타)크릴아미드, N,N-디에틸아크릴(메타)크릴아미드, N,N-프로필(메타)크릴아미드, N-이소프로필(메타)크릴아미드, 모노메틸아크릴아미드, N,N-디메틸아크릴아미드, N,N-디메틸아미노프로필아크릴아미드 등이 1종 이상 이용될 수 있다. 상기 아크릴아미드 화합물이 첨가되는 경우, 그 첨가량은 고무 원료 100중량부에 대하여, 5중량부 이하인 것이 바람직하다. 아크릴아미드 화합물의 첨가량이 5중량부를 초과할 경우에는 인장강도가 급격히 저하될 수 있다. Such acrylamide compounds are (meth) acrylamide, N-methyl (meth) acrylamide, N-ethyl (meth) acrylamide, N, N-diethylacryl (meth) acrylamide, N, N-propyl (meth) Krillamide, N-isopropyl (meth) krylamide, monomethyl acrylamide, N, N-dimethyl acrylamide, N, N-dimethylaminopropyl acrylamide, etc. can be used 1 or more types. When the said acrylamide compound is added, it is preferable that the addition amount is 5 weight part or less with respect to 100 weight part of rubber raw materials. When the amount of the acrylamide compound added exceeds 5 parts by weight, the tensile strength may drop rapidly.
또한, 고무 발포 단열재 혹은 그 원료는 적색 안료 또는 회색 안료를 더 포함할 수 있다. 이를 통하여, 고무 발포 단열재에 적색 또는 회색을 부여할 수 있으며, 본 발명에 따른 덕트 보온 커버가 적색이나 회색이 요구될 때 해당하는 색을 나타낼 수 있도록 한다. 상기 적색 안료 또는 회색 안료가 포함될 경우, 그 첨가량은 고무 원료 100중량부에 대하여, 5~15중량부로 첨가되는 것이 바람직하다. 안료의 첨가량이 5중량부 미만일 경우, 고무 발포 단열재의 적색 또는 회색 발현이 불충분할 수 있다. 반대로, 안료의 첨가량이 15중량부를 초과하는 경우, 신율 등의 물성이 저하될 수 있다.
In addition, the rubber foam insulation or the raw material may further include a red pigment or a gray pigment. Through this, it is possible to give red or gray to the rubber foam insulation, so that the duct insulation cover according to the present invention can exhibit a corresponding color when red or gray is required. When the red pigment or the gray pigment is included, the addition amount is preferably added to 5 to 15 parts by weight with respect to 100 parts by weight of the rubber raw material. If the added amount of the pigment is less than 5 parts by weight, the red or gray expression of the rubber foam insulation may be insufficient. On the contrary, when the addition amount of the pigment exceeds 15 parts by weight, physical properties such as elongation may be lowered.
상기 고무 발포 단열재는 원료 혼합 단계, 숙성 단계, 압출 단계 및 발포 단계를 포함하는 일련의 과정으로 제조될 수 있다. The rubber foam insulation may be manufactured by a series of processes including raw material mixing step, aging step, extrusion step and foaming step.
원료 혼합 단계에서는 전술한 고무 발포 단열재의 성분들 및 발포제를 혼합한다. 발포제는 AC(Azodicarbonamide) 발포제 등 공지된 다양한 발포제를 이용할 수 있다. 상기 발포제는 고무 원료 100중량부에 대하여, 1~20중량부로 첨가되는 것이 바람직하다. 발포제 함량이 1중량부 미만일 경우, 그 첨가 효과가 불충분하다. 반대로, 발포제 함량이 20중량부를 초과하는 경우, 가스 발생량 증가로 인하여 고무 발포 단열재 내부에 기포를 형성할 수 있다. In the raw material mixing step, the above-mentioned components of the rubber foam insulation and the blowing agent are mixed. The blowing agent may use various known blowing agents such as AC (Azodicarbonamide) blowing agent. It is preferable that the said foaming agent is added in 1-20 weight part with respect to 100 weight part of rubber raw materials. If the blowing agent content is less than 1 part by weight, the effect of addition thereof is insufficient. On the contrary, when the foaming agent content exceeds 20 parts by weight, bubbles may be formed inside the rubber foam insulation due to an increase in gas generation amount.
다음으로, 숙성 단계에서는 혼합된 원료를 숙성한다. 이러한 숙성은 대략 40~140℃에서 5~50분 정도 실시될 수 있다. Next, in the aging step, the mixed raw materials are aged. This aging may be carried out for about 5 to 50 minutes at about 40 ~ 140 ℃.
다음으로, 압출 단계에서는 숙성된 원료를 압출 다이를 이용하여 압출한다. Next, in the extrusion step, the aged raw material is extruded using an extrusion die.
다음으로, 발포 단계에서는 압출된 원료를 발포한다.Next, in the foaming step, the extruded raw material is foamed.
발포는 일반적으로, 80~110℃ 정도에서 수행되는 가류 과정, 115~130℃ 정도에서 수행되는 예비 발포 과정, 130~180℃ 정도에서 수행되는 본 발포 과정 및 150~170℃ 정도에서 수행되는 발포숙성 과정으로 세분화되나, 반드시 이에 제한되는 것은 아니며, 발포 단계에 포함되는 여러 과정 및 온도 조건 등은 발포제의 종류 혹은 발포 장비 등의 특성에 따라 달라질 수 있다.
Foaming is generally a vulcanization process performed at about 80 to 110 ° C., a preliminary foaming process to be performed at about 115 to 130 ° C., the present foaming process to be performed at about 130 to 180 ° C., and foam maturation performed at about 150 to 170 ° C. The process is subdivided into, but not necessarily limited to, various processes and temperature conditions included in the foaming step may vary depending on the type of foaming agent or the characteristics of the foaming equipment.
다음으로, 점착층(120)은 아크릴 수지 100 중량부에 대하여 20~30중량부로 첨가되는 소석회를 함유하는 점착제로 형성된다. 이와 같이, 소석회가 아크릴 수지 100 중량부에 대하여 20~30중량부로 첨가되고, 또한, 터펜 페놀 수지 30~50중량부, 트리페닐 포스페이트 5~10중량부, 산화아연 3~5중량부, 폴리디메틸실옥산 4~8중량부가 첨가된 점착제를 이용한 결과, 난연성 및 밀착성이 모두 우수하였다. Next, the pressure-
이때, 소석회의 첨가량이 20중량부 미만일 경우, 난연성 향상 효과가 다소 미흡하였다. 반면, 소석회의 첨가량이 30중량부를 초과하는 경우, 난연성은 우수한 반면 밀착성이 불충분하여 덕트로부터 덕트 보온 커버가 박리되는 현상이 발생할 수 있다. At this time, when the amount of added slaked lime was less than 20 parts by weight, the effect of improving flame retardancy was somewhat insufficient. On the other hand, when the amount of added slaked lime exceeds 30 parts by weight, the flame retardancy is excellent but the adhesion is insufficient, the phenomenon that the duct insulation cover may be peeled off from the duct.
또한, 터펜 페놀 수지가 30중량부 미만일 경우, 점착제의 열경화 특성이 미흡하였고, 터펜 페놀 수지가 50중량부를 초과하는 경우, 난연성이 저하되는 문제점이 있다. In addition, when the terpene phenol resin is less than 30 parts by weight, the thermosetting characteristics of the pressure-sensitive adhesive is insufficient, when the terpene phenol resin exceeds 50 parts by weight, there is a problem that the flame retardancy is lowered.
트리페닐 포스페이트, 산화아연 및 폴리디메틸실옥산의 경우, 난연성 혹은 밀착성을 향상시키기 위하여 첨가된 것으로, 상기 제시된 첨가량에 미치지 못하는 경우, 난연성 혹은 밀착성 향상이 불충분하였고, 반대로 상기 제시된 첨가량을 벗어나는 경우, 난연성이 향상되지만 밀착성이 저하되거나 밀착성이 향상되지만 난연성이 저하되는 문제점이 있다. In the case of triphenyl phosphate, zinc oxide and polydimethylsiloxane, it was added to improve the flame retardancy or adhesiveness, and if it does not reach the above-mentioned addition amount, the flame retardancy or adhesion improvement was insufficient, and on the contrary, when it was out of the above-mentioned addition amount, Although this improves, the adhesiveness is lowered or the adhesiveness is improved, but there is a problem that the flame retardancy is lowered.
본 발명에 따른 덕트 보온 커버 형성 방법은 NBR 고무 발포 단열재 또는 EPDM 고무 발포 단열재의 원료를 혼합하고, 숙성한 후, 압출 및 발포하여 고무 발포 단열재를 제조하는 단계와, 상기 고무 발포 단열재 표면에, 아크릴 수지 100 중량부에 대하여 20~30중량부로 첨가되는 소석회를 함유하는 점착제를 도포하는 단계와, 덕트를 감싸는 형태로, 상기 소석회를 함유하는 점착제가 도포된 고무 발포 단열재를 상기 덕트에 부착하는 단계를 포함할 수 있다.

1) 인장강도 및 신율1) Tensile strength and elongation
IEC-60811-1-1규격에 따라 인장강도와 신율을 측정하였다.Tensile strength and elongation were measured according to IEC-60811-1-1.

3) 난연성3) flame retardant
국제 난연 기준인 BS 476 Part-6 등에 준하여 Class "0", "1", "2"로 나타내었으며, Class "0"일 때 난연성이 가장 우수하다.
Class "0", "1", "2" in accordance with the international flame retardant standards BS 476 Part-6, etc., and when the class "0" is the best flame retardancy.
표 1은 실시예 1~6 및 비교예 1~5에 따른 덕트 보온 커버에 대한 물성 평가 결과를 나타낸 것이다. Table 1 shows the physical property evaluation results for the duct insulation cover according to Examples 1 to 6 and Comparative Examples 1 to 5.
[표 1][Table 1]
표 1을 참조하면, 실시예 1~6에 따른 덕트 보온 커버의 경우, 인장강도 : 87~95Kgf/cm2 및 신율 : 507~596%로 각각 측정되었다. 또한, 실시예 1~6에 따른 시편의 경우, 한계 산소 지수(LOI) : 34~37을 나타내어, 목표로 하는 LOI 30 이상을 만족하였으며, 모두 Class "0"의 난연성을 나타내었다. Referring to Table 1, in the case of the duct insulation cover according to Examples 1 to 6, tensile strength: 87 ~ 95Kgf / cm 2 and elongation: 507 ~ 596%, respectively. In addition, in the case of the specimens according to Examples 1 to 6, the limit oxygen index (LOI): 34 ~ 37 was expressed, satisfying the target LOI 30 or more, all showed a flame retardancy of Class "0".
특히, 아크릴 아미드 화합물이 적정량 첨가된 실시예 2 및 실시예 5에 따른 덕트 보온 커버의 경우, 다른 실시예들 보다도 신율이 보다 높았다. In particular, in the case of the duct insulation cover according to Examples 2 and 5 to which the appropriate amount of acrylamide compound was added, the elongation was higher than that of the other examples.
또한, 고무 원료로 NBR을 사용한 실시예 1~3에 따른 덕트 보온 커버와 고무 원료로 EPDM을 사용한 실시예 4~6에 따른 덕트 보온 커버를 비교할 때, 한계 산소 지수의 경우 NBR을 사용할 경우가 약간 더 우수하였고, 신율의 경우도, NBR을 사용하였을 때가 약간 더 우수하였다.
In addition, when comparing the duct insulating cover according to Examples 1 to 3 using NBR as the rubber raw material and the duct insulating cover according to Examples 4 to 6 using EPDM as the rubber raw material, NBR is slightly used for the limit oxygen index. It was better, and elongation was slightly better with NBR.
반면, 폴리테트라플루오르에틸렌이 상대적으로 적게 첨가되고, 산화몰리브덴이 첨가되지 않은 비교예 1~2에 따른 덕트 보온 커버의 경우, 한계 산소 지수가 36 미만으로 상대적으로 발연억제성이 불충분하였다.On the other hand, in the case of the duct insulation cover according to Comparative Examples 1 to 2 in which relatively little polytetrafluoroethylene was added and no molybdenum oxide was added, the marginal oxygen index was less than 36, and the smoke inhibition was relatively insufficient.
또한, 디아미노디페닐메탄 및 인산에스테르가 상대적으로 많이 첨가된 비교예 2에 따른 덕트 보온 커버의 경우, 신율이 500%에 미치지 못하였다.In addition, in the case of the duct insulation cover according to Comparative Example 2 in which diaminodiphenylmethane and phosphate ester were relatively added, the elongation was less than 500%.
또한, 아크릴 아미드 화합물이 과다 첨가된 비교예 3의 경우, 인장강도가 80 Kgf/cm2에 미치지 못하였다. In addition, in Comparative Example 3 in which the acryl amide compound was excessively added, the tensile strength did not reach 80 Kgf / cm 2 .
또한, 회색 안료가 첨가된 실시예 3, 6 및 비교예 4에 따른 덕트 보온 커버 모두 색상을 나타내었으나, 회색 안료가 과다 첨가된 비교예 4에 따른 덕트 보온 커버의 경우, 신율이 500% 미만으로 감소되었다. In addition, although the duct insulating cover according to Examples 3, 6 and Comparative Example 4 to which the gray pigment was added showed color, the duct insulating cover according to Comparative Example 4 to which the gray pigment was added was less than 500%. Reduced.
또한, 소석회가 첨가되지 않은 점착제를 이용한 비교예 5에 따른 덕트 보온 커버의 경우, Class "2"의 난연성을 나타내어, 실시예 1에 비하여 상대적으로 낮은 난연성을 나타내었다.
In addition, in the case of the duct insulation cover according to Comparative Example 5 using the pressure-sensitive adhesive without the addition of slaked lime, the flame retardance of Class "2" was shown, and it showed relatively low flame retardancy compared with Example 1.
