Abstract

Phosphoric ester compound was employed as thermal resistant and flame retardant for chlorinated polyethylene(CPE) rubber material which is used to prepare automotive oil cooler hose. Cure characteristics, physical properties, thermal resistance, and flame retardation of CPE rubber compounds were investigated. CPE rubber which has excellent properties such as cold resistance and chemical corrosion resistance, and is inexpensive in price than existing ethyleneacrylate rubber(EAR) was used to prepare a rubber compound useful for hose. A non-halogen flame retarding agent N,N'-bis- (diphenylphosphoro) diaminohexane(BDPDH), which is condensed phosphoric ester, was synthesized and it was mixed to CPE rubber material with the range of $0{\sim}30 phr$. From the test results, rheological properties, heat resistance, and flame retardance of CPE rubber compounds were found out to be much increased. The optimum content of BDPDH to rubber which gives maximum effect on thermal resistance and flame retardation, within the range of tolerable specification for rubber materials, was determined to be 20 phr.

자동차 Oil cooler용 호스를 구성하는 고무재료의 내열 및 난연성을 향상시키기 위하여 인산 에스테르계 화합물을 내열 및 난연제로 하여 제조한 염소화 폴리에틸렌(CPE) 배합고무의 가황 특성, 물리적 성질, 내열성, 난연성 및 변량효과를 조사하였다. 호스용 고무재료는 기존의 ethyleneacrylate rubber(EAR)보다 화학적 내식성과 내한성이 우수하면서도 가격이 저렴한 CPE 고무재료를 사용하였으며, 난연제는 비할로겐 축합 인산 에스테르계인 N,N'-bis-(diphenylphosphoro) diaminohexane(BDPDH)를 합성하여 CPE 고무재료와 $0{\sim}30 phr$ 범위에서 혼련하였다. 배합고무시편의 경도, 인장강도, 신율, 인장응력 및 열적 특성을 측정한 결과, CPE 배합고무의 유동성, 난연성, 내열성이 향상되었음을 확인하였으며, 고무재료 규격을 초과하지 않는 범위 내에서 최대의 내열 및 난연 효과를 주는 BDPDH의 배합량은 20 phr로 나타났다.
