Description
본 발명은 철도차량 케이블용 시스 재료 조성물에 관한 것이다.The present invention relates to a sheath material composition for a railway vehicle cable.
철도차량 케이블은 일반 케이블에 비해 매우 가혹한 조건에서 사용되므로 내열성, 내유성 등에 있어서 뛰어난 특성을 갖추어야 하며, 하네스 작업이나 케이블 간의 마찰 등에 의해 발생하는 마모에 견딜 수 있는 내마모성을 가져야 한다. 또한 철도차량에 화재가 발생하였을 때 인명과 화물 및 장비의 안전성 확보와 손실의 최소화를 위해서는 난연성 등의 화재 안정성을 필수적으로 갖추어야 한다.Railway vehicle cables are used in very severe conditions compared to ordinary cables, so they must have excellent characteristics such as heat resistance and oil resistance, and must have abrasion resistance that can withstand wear caused by harness work or friction between cables. In addition, fire safety such as flame retardancy must be essential to ensure safety of life, cargo and equipment and minimization of loss when a railway vehicle fires.
종래에는 주로 철도차량 케이블의 시스 재료로서 폴리비닐 클로라이드, 폴리클로로프렌이나 폴리클로로네이티드 폴리에틸렌과 같이 할로겐을 함유한 기본 수지가 사용되었다. 그런데, 이러한 할로겐을 함유하는 기본 수지는 독성 지수가 높을 뿐만 아니라 난연성이 좋지 못하다는 단점이 있다.Conventionally, a basic resin containing a halogen such as polyvinyl chloride, polychloroprene or polychlorinated polyethylene as a sheath material of a railway vehicle cable has been mainly used. However, such halogen-containing basic resins have a disadvantage that they have a high toxicity index as well as poor flame retardancy.
이러한 문제점을 해결하고자, 할로겐을 포함하지 않는 기본 수지를 사용하고 할로겐-프리 난연제로서 금속 수산화물을 다량 사용하는 방법이 제시되었다. 그러나, 이러한 다량의 난연제로 인하여 기계적 물성과 고온에서의 가열 후 특성이 현저하게 저하되는 등 문제점이 생겼다.To solve these problems, there has been proposed a method of using a halogen-free base resin and using a large amount of a metal hydroxide as a halogen-free flame retardant. However, such a large amount of the flame retardant causes a problem that the mechanical properties and the properties after heating at a high temperature are remarkably lowered.
상기와 같은 문제점을 해결하기 위하여 본 발명은 난연성과 내마모성이 뛰어난 철도차량 케이블용 시스 재료 조성물을 제공한다.In order to solve the above problems, the present invention provides a sheath material composition for a railway vehicle cable excellent in flame retardancy and abrasion resistance.
상기 목적을 달성하기 위하여, 본 발명의 난연성과 내마모성이 뛰어난 철도차량 케이블용 시스 재료 조성물은 열가소성 폴리에스테르 엘라스토머(TPEE) 수지 20 내지 60 중량%, 에틸렌 비닐 아세테이트(EVA) 수지 35 내지 65 중량% 및 말레산 무수물로 그래프트된 폴리에틸렌(PE) 수지 또는 에틸렌 비닐 아세테이트(EVA) 수지 5 내지 30 중량%가 혼합된 혼합 수지를 기본수지로 사용하며, 상기 기본 수지 100 중량부에 대하여, 난연제 130 내지 180 중량부를 포함한다.In order to achieve the above object, the sheath material composition for a railway vehicle cable excellent in flame retardancy and abrasion resistance of the present invention comprises 20 to 60 wt% of a thermoplastic polyester elastomer (TPEE) resin, 35 to 65 wt% of an ethylene vinyl acetate (EVA) (PE) resin grafted with maleic anhydride or 5 to 30% by weight of an ethylene vinyl acetate (EVA) resin is used as a base resin, and a flame retardant 130 to 180 weight .
본 발명의 시스 재료 조성물을 이용하여 제조한 시스는 난연성 및 내마모성이 우수하여 철도차량 케이블에 유용하게 적용할 수 있다.The sheath produced by using the sheath material composition of the present invention is excellent in flame retardancy and abrasion resistance and can be applied to railway vehicle cables.

If the content of the maleic anhydride is less than 0.6%, the interfacial bonding strength between the flame retardant and the base resin is weakened and the abrasion resistance is lowered. When the content of the maleic anhydride exceeds 3%, the abrasion resistance is improved but the manufacturing cost is increased There are disadvantages.
상기 말레산 무수물로 그래프트된 폴리에틸렌(PE) 수지 또는 에틸렌 비닐 아세테이트(EVA) 수지는 0.5 내지 5 g/10분의 용융지수(MI)를 가지며, 바람직하게 0.5 내지 3 g/10분의 용융지수(MI)를 갖는다. 상기 용융지수와 관련하여 0.5 g/10분 미만인 경우에는 흐름성이 낮아 압출 가공시 부하가 많이 걸리고 외관이 좋지 못하며, 5 g/10분을 초과하는 경우에는 가공성은 우수하나 내마모성 등의 물성이 저하된다. The polyethylene (PE) resin or ethylene vinyl acetate (EVA) resin grafted with maleic anhydride has a melt index (MI) of 0.5 to 5 g / 10 min, preferably a melt index of 0.5 to 3 g / 10 min MI). When the melt index is less than 0.5 g / 10 min, the flowability is low, which causes a lot of load in the extrusion process and the appearance is poor. When the melt index is more than 5 g / 10 min, the workability is excellent, do.
이러한 말레산 무수물로 그래프트된 폴리에틸렌(PE) 수지 또는 에틸렌 비닐 아세테이트(EVA) 수지는 기본수지의 5 내지 30 중량%로 함유되며, 바람직하게 5 내지 15 중량%로 함유된다. 상기 함량과 관련하여 5 중량% 미만인 경우에는 내마모성이 저하되며, 30 중량%를 초과하는 경우에는 내마모성은 향상되나 유연성이 저하된다.The polyethylene (PE) resin or the ethylene vinyl acetate (EVA) resin grafted with maleic anhydride is contained in an amount of 5 to 30% by weight, preferably 5 to 15% by weight of the base resin. When the content is less than 5% by weight, abrasion resistance is deteriorated. When the content is more than 30% by weight, abrasion resistance is improved but flexibility is decreased.

상기 난연성(IEC 60332-1) 시험에서 실시예 1 내지 3 및 비교예 1 내지 7 모두, 하부로부터 연소한 길이가 30 ~ 50 mm로서 기준치를 만족하여 표 2에 하부로부터 연소한 길이는 생략하였다. In the flame retardancy (IEC 60332-1) test, in all of Examples 1 to 3 and Comparative Examples 1 to 7, the burned length from the bottom was 30 to 50 mm and the reference value was satisfied, and the burned length from the bottom in Table 2 was omitted.
한편, 상기 표 2의 결과로부터 알 수 있는 바와 같이, 본 발명의 경우 2 종류의 난연성 시험에서 모두 기준치를 만족하였고 내마모성도 상당히 우수하였다.On the other hand, as can be seen from the results of Table 2, in the case of the present invention, all of the two kinds of flame retardancy tests satisfied the standard values and the abrasion resistance was remarkably excellent.
반면, 비교예 1의 경우 본 발명에 비하여 내마모성이 상당히 미약하였으며, 이러한 결과가 발생한 것은 본 발명에서 한정한 입자 크기를 벗어난(1.5 마이크로미터 초과) 난연제를 사용하였기 때문이다.On the other hand, in the case of Comparative Example 1, the abrasion resistance was much weaker than in the present invention, and the result was that the flame retardant exceeding the particle size defined in the present invention (exceeding 1.5 micrometers) was used.
비교예 2의 경우에도 본 발명에 비하여 내마모성이 상당히 미약하였으며, 이러한 결과가 발생한 것은 표면처리가 되지 않은 난연제를 사용하였기 때문이다.Also in the case of Comparative Example 2, the abrasion resistance was much weaker than in the present invention, and the result was that the flame retardant which was not surface-treated was used.
비교예 3의 경우에도 본 발명에 비하여 내마모성이 상당히 미약하였으며, 이러한 결과가 발생한 것은 본 발명에서 한정한 모스 경도보다 작은 모스 경도(1)를 갖는 난연제를 사용하였기 때문이다.Also in Comparative Example 3, the abrasion resistance was much weaker than in the present invention. The reason for this result is that a flame retardant having a Mohs hardness (1) smaller than the Mohs hardness defined in the present invention was used.
비교예 4의 경우에도 본 발명에 비하여 내마모성이 상당히 미약하였으며, 이러한 결과가 발생한 것은 본 발명에서 한정한 말레산 무수물의 함량보다 작은 함량(0.5 %)을 가진 말레산 무수물로 그래프트된 폴리에틸렌(PE) 수지를 사용하였기 때문이다.In the case of Comparative Example 4, the abrasion resistance was remarkably weaker than that of the present invention. The result was that polyethylene (PE) grafted with maleic anhydride having a content (0.5%) smaller than that of the maleic anhydride defined in the present invention, Resin.
비교예 5의 경우에도 본 발명에 비하여 내마모성이 상당히 미약하였으며, 이러한 결과가 발생한 것은 본 발명에서 한정한 용융지수(MI)보다 큰(17 g/10분) 용융지수를 갖는 말레산 무수물로 그래프트된 폴리에틸렌(PE) 수지를 사용하였기 때문이다.Also in the case of Comparative Example 5, the abrasion resistance was considerably weaker than in the present invention. The results were obtained by grafting maleic anhydride having a melt index (17 g / 10 min) larger than the melt index Because of the use of polyethylene (PE) resin.
비교예 6의 경우에도 본 발명에 비하여 내마모성이 상당히 미약하였으며, 이러한 결과가 발생한 것은 본 발명에서 한정한 함량보다 많은(190 중량부) 함량의 난연제를 사용하였기 때문이다.Also in the case of Comparative Example 6, the abrasion resistance was considerably weaker than in the present invention. The reason for this result was that the flame retardant was used in an amount exceeding the content defined in the present invention (190 parts by weight).
비교예 7의 경우 내마모성은 우수하였으나, 난연성 시험에서 기준치를 만족하지 못하였다. 이러한 결과가 발생한 것은 본 발명에서 한정한 함량보다 적은(120 중량부) 함량의 난연제를 사용하였기 때문이다.
In the case of Comparative Example 7, the abrasion resistance was excellent, but the flammability test did not satisfy the reference value. This is because a flame retardant having a content of less than the content defined in the present invention (120 parts by weight) was used.
위와 같이 본 발명의 최적 실시예들을 개시하였다. 본 실시예를 포함하는 명세서에서 특정한 용어들이 사용되었으나, 이는 단지 당업자에게 본 발명을 상세히 설명하기 위한 목적에서 사용된 것이지 의미를 한정하거나 특허청구범위에 기재된 본 발명의 범위를 제한하기 위해 사용된 것이 아님을 밝혀 둔다.
