상기 절연부재(20)는 난연성을 갖도록 난연제가 포함되며, 난연성을 위해 EPDM 고무 40~53중량부에, 물성을 향상시키는 물성향상제 7~12 중량부와, 가공안정성을 향상시키는 가소제 3~6 중량부와, 난연성을 갖도록 하는 난연제 23~31 중량부와, 내열안정성을 향상시키는 내열안정제 2~5중량부와, 노화방지용 노화방지제 1~2.2 중량부와, 가공조제 1.5~3 중량부와, 가교제 3.5~5.3 중량부를 포함한다.  The insulating member 20 includes a flame retardant to have a flame retardancy, for the flame retardant 40 to 53 parts by weight of EPDM rubber, 7 to 12 parts by weight of a physical property improving agent to improve physical properties, and 3 to 6 weight of a plasticizer to improve processing stability And 23 to 31 parts by weight of a flame retardant to have flame retardancy, 2 to 5 parts by weight of a heat stabilizer to improve heat stability, 1 to 2.2 parts by weight of an anti-aging antioxidant, 1.5 to 3 parts by weight of a processing aid, a crosslinking agent Contains 3.5 to 5.3 parts by weight.

여기서 바람직한 실시예로는 표1에 보인 바와 같이 난연성을 위해 EPDM 고무 46.7 중량부에, 물성을 향상시키는 점토 9.3 중량부와, 가공안정성을 향상시키는 가소제 4.7 중량부와, 난연성을 갖도록 하는 난연제 27 중량부와, 내열안정성을 향상시키는 내열안정제 3.3 중량부와, 노화방지용 노화방지제 1.8 중량부와, 가공조제 2.3 중량부와, 가교제 4.7 중량부로 함이 바람직하다.In this preferred embodiment, as shown in Table 1, 46.7 parts by weight of EPDM rubber for flame retardancy, 9.3 parts by weight of clay to improve physical properties, 4.7 parts by weight of plasticizer to improve processing stability, and 27 weight of flame retardant to have flame retardancy.

상기 EPDM 고무는 그리고 에틸렌과 프로필렌 그리고 여기에 가황작용을 위해 혼합되는 헥사디엔, 디사이클로 펜타디엔, 에틸렌노르보르넨 중에 하나 이상을 포함하여 중합된 합성수지로, 내후성, 내오존성, 내열성에 우수하고, 내한성, 내수성, 전기적 특성 및 내약품성이 우수한 난연성을 갖지 않는 상태의 가연성이며, 1의 비중을 갖는 물보다 작은 0.86의 비중을 갖는다. The EPDM rubber is a synthetic resin polymerized by ethylene, propylene and at least one of hexadiene, dicyclo pentadiene and ethylene norbornene mixed for vulcanization, and excellent in weather resistance, ozone resistance and heat resistance. It is flammable in a state without cold resistance, water resistance, electrical properties, and chemical resistance, and has a specific gravity of 0.86 which is smaller than water having a specific gravity of 1.

이때 에틸렌의 함량에 따라 가공성과 물리적인 특성의 변화를 줄 수 있는데 에틸렌의 함량이 적으면 가공성은 향상될 수 있고, 에틸렌의 함량이 높으면, 물리적인 특성을 향상될 수 있다.In this case, the processability and physical properties may be changed according to the content of ethylene. If the content of ethylene is low, the processability may be improved. If the content of ethylene is high, the physical properties may be improved.

그리고 물성향상제는 물리적인 특성 및 내약품성을 더욱 향상시키는 것으로 점토가 적용된다. And the physical property improver is applied to clay to further improve the physical properties and chemical resistance.

여기서 무기질계는 드리핑 방지 효과의 증강과 함께 수지 조성물의 기계적 강도를 향상시키는 특성을 가지고 있으나, 무기질계가 많아지면 성형성이 떨어지므로 적절하게 혼합하는 것이 좋다.In this case, the inorganic type has the property of improving the mechanical strength of the resin composition together with the enhancement of the anti-dripping effect. However, when the inorganic type increases, the formability is inferior.

그리고 무기질계는 ATH(Aluminium Tri- Hydroxide), MDH이다. ATH는 저연성 비 할로겐 난연제이며, 할로겐 난연제인 브롬계과 함께 사용하면 높은 난연성과 낮은 연기 발생으로 최근의 친환경적 난연화 추세에 적합한 난연제이다. 이때 할로겐 난연제로 브롬계(PBBs, PBDEs)로 한정하지 않고, 인산계난연제, 삼산화안티몬 등이 적용될 수 있다. And inorganic type is ATH (Aluminum Tri- Hydroxide), MDH. ATH is a low flame retardant non-halogen flame retardant, and when used in combination with a halogen flame retardant bromine-based, it is a flame retardant suitable for the recent environmentally friendly flame retardant trend with high flame retardancy and low smoke generation. The halogen flame retardant is not limited to bromine (PBBs, PBDEs), phosphate-based flame retardant, antimony trioxide may be applied.

또한, 할로겐을 함유하는 브롬계는 열에 의한 연소과정에서 라디칼과 반응하여 연소를 중지시킨다.In addition, the bromine system containing halogen reacts with radicals in the combustion process by heat to stop combustion.

그리고 수지에 혼합하여 가공과 완성된 제품의 사용기간 중 물리적, 화학적 성질을 유지하도록 도와주는 내열안정제는 금속산화물 조제를 사용하며, 제품 형태상 저장 안정성이 뛰어나고 계량과 취급이 용이하며 최적의 분산효과를 준다. 이러한 내열안정제로는 주로 납 안정제, Ba-Cd, Ca-Zn, Ba-Zn 등의 금속석검계 안정제와 Orgnotin 안정제가 적용될 수 있다. The heat stabilizer, which is mixed with the resin to help maintain the physical and chemical properties during the processing and use of the finished product, uses a metal oxide preparation, and has excellent storage stability, easy weighing and handling, and optimal dispersing effect. Gives. As such heat stabilizers, lead stabilizers, Ba-Cd, Ca-Zn, Ba-Zn and other metal-based stabilizers and Orgnotin stabilizers may be applied.

상기 노화방지제는 페놀(Phenol)계 0.5~1.5중량부와 아민(Amine)계 0.5~1.5중량부를 혼합하여서 되며, 바람직하게는 페놀(Phenol)계 0.9중량부와 아민(Amine)계 0.9중량부를 혼합하여 열노화, 기계적인 노화등과 같은 노화현상을 억제한다.The anti-aging agent is a mixture of 0.5 to 1.5 parts by weight of phenol (phenol) and 0.5 to 1.5 parts by weight of amine (Amine), preferably 0.9 parts by weight of phenol (Phenol) and 0.9 parts by weight of amine (Amine) It suppresses the aging phenomenon such as thermal aging and mechanical aging.

가공조제는 금속(Metallic)염 0.5~2.0 중량부와, 실리콘(Silicone)계 0.5~1.5 중량부를 혼합하되 바람직하게는 금속(Metallic)염 1.3 중량부와, 실리콘(Silicone)계 0.9 중량부를 혼합하여 되며, 비교적 적은 양을 투입함으로서 가공성을 향상시킨다.The processing aid may be mixed with 0.5 to 2.0 parts by weight of a metal salt, 0.5 to 1.5 parts by weight of a silicon-based salt, preferably 1.3 parts by weight of a metal salt, and 0.9 parts by weight of a silicon-based salt. It is possible to improve the workability by introducing a relatively small amount.

그리고 가교제는 선상고분자 화합물의 분자를 서로 화학결합시켜 그물구조를 취하기 위한 물질을 말하며, 유기과산화물이 적용된다.The crosslinking agent refers to a substance for chemically bonding molecules of linear polymer compounds to each other to take a network structure, and an organic peroxide is applied.
