Bellows-type rubber hoses for use in automobiles |
摘要 |
A novel rubber composition is disclosed for use in the preparation of bellows-type rubber hoses for installation in automobile engine compartments. The rubber composition of the present invention contains a chlorinated ethylene-propylene copolymer as base rubber, a triazine-based vulcanizing agent, an acid-acceptor comprising magnesium oxide and hydrotalcite, a sulfur-containing organic carboxylic acid releasing enhancer, and a thioether-based antioxidant heat resistance enhancer. The disclosed bellows-type rubber hoses exhibit excellent heat and ozone resistance, sufficient rigidity to permit a reduction in wall thickness in order to withstand negative pressures associated with automobile engine environments and are amenable to molding with limited impact on releasing characteristics.
