Description

내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조{Outer cover structure of heat proximity suit's fabric for enhancing to flex resistant and radiation protective performance}Outer cover structure of heat proximity suit's fabric for enhancing to flex resistant and radiation protective performance}

본 발명은 방열복 원단의 겉감에 관한 것으로, 더욱 상세하게는 겉감의 구조층 개선을 통해 복사열의 차단율 향상과, 내구성의 향상이 가능하게 하는 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조에 관한 것이다.The present invention relates to an outer surface of a heat radiation suit fabric, and more particularly, to an outer structure of a heat radiation suit fabric with improved bending resistance and radiant heat performance enabling improved durability and improved shielding rate of radiant heat through improvement of the outer structure layer. .

일반적으로, 고온의 화염 속에서 소방 및 인명구조작업을 위해 화재현장으로 투입되는 소방관이나, 제철공장의 용광로에서 작업을 하는 작업자는 고온의 화염으로 부터 인체를 보호함과 함께 고온의 복사열을 역반사 시키기 위하여 방열복을 착용하게 된다.In general, firefighters who are put into the fire site for firefighting and lifesaving work in a high-temperature flame, or workers working in a furnace of a steel mill protect the human body from high-temperature flames and retroreflect high-temperature radiant heat. In order to do so, you will wear a heat shield.

이와 같은 방열복은 방열 상의와 방열 하의, 방열 장갑, 방열 두건 및 방열화로 이루어진다.Such a heat radiation suit consists of a heat radiation top and a heat radiation bottom, heat radiation gloves, heat radiation hood, and heat radiation boots.

한편, 기존의 산업안전보건공단 및 한국소방산업기술원에서 정하고 있는 방열복 기준에서는, 아라미드(Aramid) 원단에 접착제를 코팅 및 알루미늄의 증착 처리가 이루어진 내열 피복소재를 겉감으로 이용하며, 안감으로는 아라미드 내열원단이 이용되고, 상기 겉감과 안감 사이에는 누빔 처리된 휄트와 함께 내열원단, 부직포 등으로 된 내부 단열층을 이루도록 규정하고 있다.On the other hand, in the heat-resistant clothing standards established by the Occupational Safety and Health Agency and the Korea Institute of Fire Industry and Technology, a heat-resistant coating material coated with an adhesive on aramid fabric and evaporated aluminum is used as the outer material, and aramid heat-resistant as the lining. A fabric is used, and an inner insulating layer made of heat-resistant fabric, non-woven fabric, etc., along with quilted felts, is defined between the outer and the lining.

그러나 상기 규정에 따라 제작되는 종래 방열복은, 복사열을 차단하기 위해 가장 중요시되는 겉감의 구조가 단순히 아라미드 원단의 표면에 알루미늄 증착필름이 구성된 것인바, 고온의 복사열 차단율이 현저히 부족하여 내구성이 떨어져서 작업 시간이 단축되는 문제점이 있었다.However, in the conventional heat dissipation suit manufactured according to the above regulations, the most important outer structure to block radiant heat is simply that an aluminum evaporated film is formed on the surface of the aramid fabric. There was a problem with this shortening.

또한, 종래의 겉감 구조는 작업자가 활동시 수회에 걸쳐 겉감에 굴곡이 발생하게 되는 것인데, 이때 유연성이 떨어져 굴곡시나 마찰 및 충격에 의해 알루미늄 증착층에 크랙이나 마모가 쉽게 발생하는 등 내구성 저하에 따른 제대로된 성능을 발휘하지 못하고 이에 따른 방열복 교체 주기가 상당히 단축되며, 특히 액상의 화학물질 등이 내부로 침투되는 문제점이 있었다.In addition, in the conventional structure of the exterior, the exterior is bent several times during the activity of the worker.At this time, the flexibility is low, and the aluminum deposition layer is easily cracked or abrasion due to bending or friction and impact. It does not exhibit proper performance, and accordingly, the replacement cycle for heat shields is considerably shortened. In particular, there is a problem in that liquid chemicals etc. penetrate inside.

It is another object of the present invention to provide.

내열 실리콘층은 0.3~0.4㎛ 두께를 이루게 구성하며,The heat-resistant silicon layer is composed to form a thickness of 0.3 ~ 0.4㎛,

이때, 알루미늄 페이스트층은,At this time, the aluminum paste layer,

전체 100중량%에 대하여 알루미늄 은분 20~30중량%와 액상의 접착제 70~80중량%를 이루게 조성하여 됨으로 달성할 수 있는 것이다.This can be achieved by composition comprising 20 to 30% by weight of aluminum silver powder and 70 to 80% by weight of a liquid adhesive with respect to the total 100% by weight.

이상과 같이 본 발명 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조는, 난연 적착층에 의해 난연성의 향상은 물론, 알루미늄 증착층을 통해 고온의 복사열을 1차로 직접 차단하고, 이후 알루미늄 은분이 함침된 알루미늄 페이스트층을 통해 2차로 잔여 복사열의 차단이 가능하게 되는 것인바, 복사열 차단율의 현격한 향상이 가능한 효과를 얻을 수 있는 것이다.As described above, the outer structure of the heat-radiating clothing fabric with improved bending resistance and radiant heat performance of the present invention, as well as improved flame retardancy by a flame-retardant adhesion layer, first directly blocks high-temperature radiant heat through an aluminum deposition layer, and then impregnated with aluminum silver powder.

In particular, the flexibility is improved by the heat-resistant silicone layer, so that the activity of the worker is remarkably improved, and the penetration of liquids such as chemical substances is blocked.

도 1은 본 발명 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조를 나타낸 전체 분해도이고, 도 2는 본 발명 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조를 나타낸 전체 적층도이다.1 is an overall exploded view showing the outer structure of a heat-radiating clothing fabric with improved bending resistance and radiant heat performance according to the present invention, and FIG. 2 is an overall stacked view showing the outer structure of a heat-radiating suit fabric with improved bending resistance and radiant heat performance according to the present invention.

도 1 및 도 2의 도시와 같이 본 발명 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조는, 방열복의 내열원단 겉에 형성되어 고온의 작업 환경에서 복사열을 차단하여 작업자를 보호하게 구성된 것으로, 아라미드 원단(100)과, 난연 접착층(200)과, 알루미늄 페이스트층(300)과, 알루미늄 증착층(400)과, 내열 실리콘층(500)으로 구성된다.As shown in Figs. 1 and 2, the outer structure of the heat-resistant clothing fabric with improved bending resistance and radiant heat performance according to the present invention is formed on the outer surface of the heat-resistant fabric of the heat-radiating suit to block radiant heat in a high-temperature work environment to protect workers, aramid It is composed of a fabric 100, a flame retardant adhesive layer 200, an aluminum paste layer 300, an aluminum deposition layer 400, and a heat-resistant silicon layer 500.

먼저, 아라미드 원단(100)은 본 발명 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조를 구성함에 있어, 기초를 이루게 구성된다.First, the aramid fabric 100 is configured to form the basis for constructing the outer structure of the heat-radiating clothing fabric with improved bending resistance and radiant heat performance according to the present invention.

이때, 본 발명에서 적용되는 아라미드 원단(100)은 통상의 방열복에 적용되는 아라미드(Aramid) 섬유로 적용하되, 바람직하게는 20S/3 즉, 20수 3합 원단으로 구성함으로써, 내열성 및 강도를 향상시켰다.At this time, the aramid fabric 100 applied in the present invention is applied as an aramid fiber applied to a conventional heat dissipation clothing, preferably 20S/3, that is, by consisting of a 20 number 3 combination fabric, thereby improving heat resistance and strength. Made it.

상기 난연 접착층(200)은 본 발명 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조를 구성함에 있어, 상기 아라미드 원단(100)의 외표면에 형성되는 것으로, 난연성을 향상시키게 구성된다.The flame-retardant adhesive layer 200 is formed on the outer surface of the aramid fabric 100 in constituting the outer surface structure of the heat-radiating clothing fabric having improved bending resistance and radiant heat performance according to the present invention, and is configured to improve flame retardancy.

한편, 본 발명에서 난연 접착층(200)은 난연성을 가지는 접착제가 도포되어 된 것으로, 이때 난연 접착제는 새롭게 구현되는 것이 아니라 통상의 우레탄이나 폴리에스트 계열 등 다양한 난연 접착제의 적용이 가능할 것이며, 바람직하게는 상기 아라미드 원단(100)의 표면에 20~40㎛ 두께로 형성함이 바람직하다.On the other hand, in the present invention, the flame-retardant adhesive layer 200 is applied with an adhesive having flame-retardant properties, and at this time, the flame-retardant adhesive is not newly implemented, but various flame-retardant adhesives such as conventional urethane or polyester-based may be applied, preferably It is preferable to form a thickness of 20 ~ 40㎛ on the surface of the aramid fabric (100).

이때, 본 발명에서 난연 접착층(200)을 20~40㎛ 두께로 적용함은, 만약 20㎛ 미만인 경우에는 난연성이 저하되는 문제점이 있으며, 40㎛ 이상인 경우에는 난연성의 향상은 가져올 수 있으나, 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조의 전체적은 두께 상승과 중량 및 유연성의 저하를 가져오는 문제점이 있는 것인바, 본 발명에서는 20~40㎛ 두께로 적용함이 가장 바람직하다.At this time, the application of the flame-retardant adhesive layer 200 in a thickness of 20 to 40 μm in the present invention has a problem that if it is less than 20 μm, the flame retardancy is deteriorated, and if it is more than 40 μm, the flame retardancy may be improved. And, there is a problem in that the overall thickness of the outer structure of the heat-radiating clothing fabric with improved radiant heat performance is increased and the weight and flexibility are deteriorated. In the present invention, it is most preferable to apply a thickness of 20 to 40 μm.

즉, 난연 접착층(200)은 본 발명 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조에 적용시, 난연 작용을 통해 고열이나 화염 등으로부터 보호가 가능하게 한다.That is, when the flame-retardant adhesive layer 200 is applied to the outer structure of a heat-radiating clothing fabric having improved bending resistance and radiant heat performance of the present invention, it is possible to protect it from high heat or flame through a flame-retardant action.

상기 알루미늄 페이스트층(AL Paste)(300)은 본 발명 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조를 구성함에 있어, 상기 난연 접착층(200)의 표면에 형성되어 후술하는 알루미늄 증착층(400)과 더불어 복사열의 차단이 가능하게 한다.The aluminum paste layer (AL Paste) 300 is formed on the surface of the flame-retardant adhesive layer 200 to form an aluminum deposition layer 400 to be described later in constituting the outer structure of the heat-radiating clothing fabric with improved bending resistance and radiant heat performance of the present invention. In addition, it makes it possible to block radiant heat.

이를 위해, 본 발명에서 알루미늄 페이스트층(300)은 상기 난연 접착층(200)의 표면에 코팅 형성되는 것으로, 바람직하게는 20~40㎛ 두께로 형성함이 바람직하다.To this end, in the present invention, the aluminum paste layer 300 is coated on the surface of the flame-retardant adhesive layer 200, and is preferably formed to have a thickness of 20 to 40 μm.

여기서, 본 발명에서 적용되는 알루미늄 페이스트층(300)은 알루미늄 은분과 액상의 접착제가 혼합되어 구성된 것으로, Here, the aluminum paste layer 300 applied in the present invention is composed of a mixture of aluminum silver powder and a liquid adhesive,

이때, 본 발명에 적용되는 알루미늄 은분은 ㎛ 입자를 이루게 구성된 것으로, 알루미늄 페이스트층(300) 전체 100중량%에 대하여 20~30중량% 적용되며, 무수한 알루미늄 은분 입자를 통해 복사열을 난반사 시켜 차단하게 된다.At this time, the aluminum silver powder applied to the present invention is composed of µm particles, and 20 to 30% by weight is applied to the total 100% by weight of the aluminum paste layer 300, and radiant heat is diffusely reflected through countless aluminum silver powder particles to block it. .

또한, 액상의 접착제는 한정되는 것이 아니라, 다양한 접착제의 적용 가능한 것으로, 본 발명에서는 난연성을 가지는 우레탄 접착제를 적용할 수 있으며, 알루미늄 페이스트층(300) 전체 100중량%에 대하여 70~80중량% 적용되며, 상기 알루미늄 은분을 결집시겨 난연 접착층(200)에 코팅될 수 있게 한다.In addition, the liquid adhesive is not limited, but various adhesives can be applied, and in the present invention, a urethane adhesive having flame retardancy can be applied, and 70 to 80% by weight is applied to the total 100% by weight of the aluminum paste layer 300 And, by collecting the aluminum and silver powder so that it can be coated on the flame-retardant adhesive layer 200.

즉, 알루미늄 페이스트층(300)은 본 발명 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조에 적용시, 난연 작용을 통해 고열이나 화염 등으로부터 방열복 및 작업자를 보호하게 된다.That is, when the aluminum paste layer 300 is applied to the outer structure of a heat-radiating garment fabric having improved bending resistance and radiant heat performance of the present invention, the heat-radiating suit and workers are protected from high heat or flame through a flame-retardant action.

한편, 본 발명에서 알루미늄 페이스트층(300)을 20~40㎛ 두께로 적용함은, 만약 20㎛ 미만인 경우에는 알루미늄 페이스트층(300)이 너무 얇아 복사열의 차단 효과가 현저히 저하되는 문제점이 있으며, 40㎛ 이상인 경우에는 복사열의 차단 효과는 증대시킬 수 있으나, 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조의 전체적은 두께 상승과 중량 및 유연성의 저하를 가져오는 문제점이 있는 것인바, 본 발명에서는 20~40㎛ 두께로 적용함이 가장 바람직하다.On the other hand, in the present invention, when the aluminum paste layer 300 is applied in a thickness of 20 to 40 μm, if it is less than 20 μm, the aluminum paste layer 300 is too thin to significantly reduce the blocking effect of radiant heat. In the case of µm or more, the shielding effect of radiant heat can be increased, but there is a problem in that the overall thickness of the outer structure of the heat shield fabric with improved bending resistance and radiant heat performance and decrease in weight and flexibility is caused. It is most preferable to apply with a thickness of ~40㎛.

또한, 알루미늄 은분과 액상 접착제를 조성함에 있어, 각각 20~30중량%와 70~80중량%로 적용함은, 만약 알루미늄 은분이 20중량% 미만인 경우에는 그 알루미늄 은분들의 입자 간격이 증대되어 복사열의 차단 효과가 저하될 수 있으며, 30중량% 이상으로 적용하게 되면 복사열 차단율은 향상시킬 수 있으나 액상 접착제의 함량이 상대적으로 저하되어 난연 접착층(200)에 코팅이 곤란한 문제점이 있는 것인바, 본 발명에서는 알루미늄 은분 20~30중량%와 액상 접착제 70~80중량%를 적용함이 가장 바람직하다.In addition, in the composition of the aluminum silver powder and the liquid adhesive, 20 to 30% by weight and 70 to 80% by weight, respectively, are applied. If the aluminum silver powder is less than 20% by weight, the particle spacing of the aluminum silver powder increases and the radiant heat is reduced. The blocking effect may be reduced, and when applied in an amount of 30% by weight or more, the radiation heat blocking rate may be improved, but the content of the liquid adhesive is relatively reduced, so that it is difficult to coat the flame-retardant adhesive layer 200. In the present invention, It is most preferable to apply 20 to 30% by weight of aluminum silver powder and 70 to 80% by weight of a liquid adhesive.

즉, 알루미늄 페이스트층(300)은 본 발명 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조에 적용시, 알루미늄 은분을 통해 복사열의 반사 차단이 가능하게 하되, 바람직하게는 후술하는 알루미늄 증착층을 통과한 복사열을 2차로 차단하여 작업자를 보호하게 된다.That is, when the aluminum paste layer 300 is applied to the outer structure of a heat-radiating clothing fabric with improved bending resistance and radiant heat performance of the present invention, it is possible to block the reflection of radiant heat through aluminum silver powder, but preferably pass through an aluminum deposition layer to be described later. It protects workers by blocking one radiant heat secondly.

상기 알루미늄 증착층(400)은 본 발명 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조를 구성함에 있어, 상기 알루미늄 페이스트층(300)의 표면에 형성되어 복사열의 차단이 가능하게 한다.The aluminum deposition layer 400 is formed on the surface of the aluminum paste layer 300 to block radiant heat in constituting the outer structure of the heat-radiating clothing fabric having improved bending resistance and radiant heat performance according to the present invention.

한편, 본 발명에서 알루미늄 증착층(400)은 알루미늄이 알루미늄 페이스트층(300) 표면에 증착되어 알루미늄 막을 이루게 구성된 것으로, 바람직하게는 알루미늄 페이스트층(300)의 표면에 8~12㎛ 두께로 증착 형성함이 바람직하다.On the other hand, in the present invention, the aluminum deposition layer 400 is configured such that aluminum is deposited on the surface of the aluminum paste layer 300 to form an aluminum film, and is preferably deposited on the surface of the aluminum paste layer 300 to a thickness of 8 to 12 μm. It is desirable to do it.

이때, 본 발명에서 알루미늄 증착층(400)을 8~12㎛ 두께로 적용함은, 만약 8㎛ 미만인 경우에는 그 알루미늄 막이 지나치게 얇아 복사열의 차단 효과가 미비한 문제점이 있으며, 12㎛ 이상인 경우에는 복사열 차단 효과는 향상시킬 수 있으나, 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조의 전체적은 두께 상승과 유연성의 저하를 가져오는 문제점이 있는 것인바, 본 발명에서는 8~12㎛ 두께로 적용함이 가장 바람직하다.In this case, the application of the aluminum deposition layer 400 in a thickness of 8 to 12 μm in the present invention has a problem in that the aluminum film is too thin to block radiation heat if it is less than 8 μm, and if it is 12 μm or more, it blocks radiant heat. Although the effect can be improved, there is a problem in that the overall thickness of the outer structure of the heat-radiating clothing fabric with improved bending resistance and radiant heat performance is increased and the flexibility is decreased. In the present invention, it is applied with a thickness of 8 to 12 μm. desirable.

즉, 알루미늄 증착층(400)은 본 발명 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조에 적용시, 그 알루미늄 막에 의해 복사열의 1차적인 반사 차단이 가능하게 한다.That is, when the aluminum deposition layer 400 is applied to the outer structure of a heat-radiating clothing fabric having improved bending resistance and radiant heat performance of the present invention, the aluminum film enables primary reflection of radiant heat to be blocked.

상기 내열 실리콘층(500)은 본 발명 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조를 구성함에 있어, 상기 알루미늄 증착층(400)의 표면에 형성되어 상기 알루미늄 증착층(400)의 보호와, 외부로부터 이물질이 침투하는 것을 방지하면서 상기 알루미늄 증착층(400)의 유연성을 부여하게 구성된다.The heat-resistant silicon layer 500 is formed on the surface of the aluminum deposition layer 400 to protect the aluminum deposition layer 400 in constituting the outer structure of the heat-radiating clothing fabric with improved bending resistance and radiant heat performance of the present invention, It is configured to impart flexibility of the aluminum deposition layer 400 while preventing foreign substances from penetrating from the outside.

한편, 본 발명에서 내열 실리콘층(500)은 통상의 내열 실리콘이 알루미늄 증착층(400)의 표면에 코팅 형성 실리콘 막을 이루게 구성된 것으로, 바람직하게는 알루미늄 증착층(400)의 표면에 0.3~0.4㎛ 두께로 증착 형성함이 바람직하다.On the other hand, in the present invention, the heat-resistant silicon layer 500 is composed of a conventional heat-resistant silicon to form a coating-forming silicon film on the surface of the aluminum deposition layer 400, preferably 0.3 to 0.4 μm on the surface of the aluminum deposition layer 400 It is preferable to form a vapor deposition with a thickness.

이때, 본 발명에서 내열 실리콘층(500)을 0.3~0.4㎛ 두께로 적용함은, 만약 0.3㎛ 이하로 적용하면 그 실리콘 막이 지나치게 얇아 수회에 걸친 굴곡이나 마찰 및 충격으로 인해 알루미늄 증착층(400)에 크랙이나 마모 등의 훼손이 발생하는 문제점이 있으며, 만약 0.4㎛ 이상인 경우에는 알루미늄 증착층(400)의 보호 효과는 향상시킬 수 있으나, 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조의 전체적은 두께 상승과 유연성의 저하를 가져오는 문제점이 있는 것인바, 본 발명에서는 0.3~0.4㎛ 두께로 증착 형성함이 가장 바람직하다.At this time, in the present invention, the heat-resistant silicon layer 500 is applied in a thickness of 0.3 to 0.4 μm. If it is applied to a thickness of 0.3 μm or less, the silicon film is too thin, and the aluminum deposition layer 400 is formed due to bending, friction, and impact over several times. There is a problem in that damage such as cracks or abrasion occurs on the surface, and if it is more than 0.4㎛, the protective effect of the aluminum deposition layer 400 can be improved, but the overall outer structure of the heat shield fabric with improved bending resistance and radiant heat performance is There is a problem of increasing the thickness and reducing the flexibility, and in the present invention, it is most preferable to form a deposition with a thickness of 0.3 to 0.4 μm.

한편, 본 발명에서는 도 3 내지 도 5를 참조하여 상기와 같은 구조를 갖는 본 발명 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조와 종래의 방열복 원단의 겉감구조에 대하여 실질적으로 복사열을 차단하는 본 발명의 알루미늄층(a)과 종래 겉감구조의 알루미늄층(b)을 약 10회 굴곡시켜 그 "굴곡성"과 굴곡에 따른 "빛 투과성"을 비교하였다.On the other hand, in the present invention, with reference to FIGS. 3 to 5, the present invention substantially blocks radiant heat with respect to the outer structure of the heat-radiating clothing fabric having improved bending resistance and radiant heat performance and the outer structure of the conventional heat-radiating clothing fabric. The aluminum layer (a) of the invention and the aluminum layer (b) of the conventional outer structure were bent about 10 times, and the "flexibility" and "light transmittance" according to the bending were compared.

상기와 같이 본 발명 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조의 알루미늄 페이트층(300)과 알루미늄 증착층(400)과 내열 실리콘층(500)으로 된 본 발명 알루미늄층(a)은 종래의 알루미늄층(b)에 비해 굴곡시 크랙의 발생 정도가 상당히 미미하였으며, 특히 그 크랙으로 인한 빛의 투과성 또한 상당히 미미함을 알 수 있었다.As described above, the present invention aluminum layer (a) consisting of the aluminum paint layer 300 and the aluminum deposition layer 400 and the heat-resistant silicon layer 500 of the outer structure of the heat-radiating clothing fabric with improved bending resistance and radiant heat performance of the present invention is conventional Compared to the aluminum layer (b), the degree of occurrence of cracks during bending was considerably insignificant, and in particular, the transmittance of light due to the cracks was also found to be considerably insignificant.

즉, 상기와 같은 비교를 통해 알수 있듯이, 본 발명 내굴곡성 및 복사열 성능이 향상된 방열복 원단의 겉감구조는 종래의 겉감구조에 비해 내굴곡성과 복사열 차단 성능이 월등함을 알 수 있다.That is, as can be seen through the above comparison, it can be seen that the outer structure of the heat-radiating clothing fabric with improved bending resistance and radiant heat performance of the present invention has superior bending resistance and radiation heat blocking performance compared to the conventional outer structure.
