전기절연성이 향상된 라디에이터 호스 조성물 {Radiator Hose composition with improved electrical insulating property}Radiator Hose composition with improved electrical insulating property

본 발명은 전기절연성이 향상된 라디에이터 호스 조성물에 관한 것이다.The present invention relates to a radiator hose composition with improved electrical insulation.

자동차 산업의 경우 급속하게 발전하고 있는 산업이나, 그에 따른 부품의 신뢰성과 배기가스에 대한 환경적인 문제가 야기되고 있다. 자동차에 사용되는 고무부품의 경우 전체적으로 봤을 때, 극히 낮은 비율이지만 자동차의 고성능화에 따라 엔진룸의 온도가 상승하게 되어 내열성과 내구성이 우수한 고무호스 소재의 개발이 필요하게 되었다. 엔진과열을 방지하기 위해서 사용되어지는 냉각수의 경우에 물을 사용하는 수냉식이지만 겨울에 기온이 영하로 내려가면 물의 경우 얼게 되므로 일반적으로 물과 에틸렌글리콜을 50대 50의 비율로 섞은 부동액을 사용하고, 사용환경에 따라 그 비율을 달리하여 사용할 수 있다. 따라서 냉각기 고무호스의 경우 내열성이나 내부동액성의 우수성이 고무호스의 내구성에 직접적인 영향을 미친다는 것을 예측할 수 있다.In the case of the automobile industry, it is an industry that is rapidly developing, but the reliability of parts and environmental problems related to exhaust gas are caused. In the case of rubber parts used in automobiles as a whole, the ratio is extremely low, but the temperature of the engine room rises as the performance of automobiles increases, and it is necessary to develop rubber hose materials with excellent heat resistance and durability. In the case of coolant used to prevent engine overheating, water is a water-cooled type, but when the temperature drops below zero in winter, water freezes, so in general, an antifreeze mixed with water and ethylene glycol in a ratio of 50 to 50 is used. It can be used in different proportions depending on the usage environment. Therefore, in the case of a cooler rubber hose, it can be predicted that the excellent heat resistance and antifreeze resistance directly affect the durability of the rubber hose.

지금까지 호스고무는 주로 일반 EPDM고무와 보강제 즉 카본블랙으로 만들어져 차량용에서 엔지니어링 콤포넌트로 사용되어 왔으며, 현재에도 대부분의 호스고무는 EPDM으로 적용되고 있다.Until now, hose rubber is mainly made of general EPDM rubber and reinforcing agent, that is, carbon black, and has been used as an engineering component for vehicles, and most of the hose rubber is applied as EPDM.

일반 EPDM 고무는 호스로서의 좋은 특성을 지니고 있으나, 내구성이나 내열성의 측면에서 적용에 제약을 받는다. 특히 자동차의 호스고무의 측면에서 보면, 자동차의 엔진룸의 복잡한 구조로 인하여 엔진룸의 온도가 상승하고, 자동차의 성능의 향상으로 고속주행의 시간이 늘어남에 따라 엔진룸의 온도는 일반 EPDM 고무가 견디기 어려운 온도대까지 상승하고 있다.General EPDM rubber has good characteristics as a hose, but its application is limited in terms of durability and heat resistance. In particular, in terms of the hose rubber of automobiles, the temperature of the engine room rises due to the complex structure of the engine room of the automobile, and as the time for high-speed driving increases due to the improvement of the performance of the automobile, the temperature of the engine room is lower than that of the general EPDM rubber It is rising to a temperature that is difficult to bear.

이에 따라 다수의 자동차 메이커들은 이러한 일반 EPDM 고무의 단점들을 극복하고자 합성고무의 적용을 시도하고 있으나, 아직까지 이렇다 할 결과가 도출되지 않고 있다.Accordingly, many car makers are attempting to apply synthetic rubber to overcome the shortcomings of general EPDM rubber, but the results have not been drawn so far.
