国外半钢子午线轮胎纤维骨架材料的应用分析 总被引:1,自引:2,他引:1
对近几年国外原配和替换轮胎市场不同用途的代表规格轿车和轻载子午线轮胎纤维骨架材料剖析数据进行分析。轿车子午线轮胎胎体采用聚酯帘布的范围扩大,日本、美国、欧洲均采用,V和W速度级高档、高性能替换轮胎也部分采用聚酯帘布;欧洲、日本、美国的一些高速度级(Z级)或高档车配套轮胎仍使用人造丝帘布;轻载子午线轮胎几乎全部采用聚酯帘布;帘布品种规格范围也在扩大。几乎所有轿车子午线轮胎和大部分轻载子午线轮胎设置了冠带层,以锦纶帘布为主,部分采用芳纶或芳纶/锦纶混杂(2股芳纶/1股锦纶)帘布。轮胎胎体均较柔软,静负荷下沉量大,乘坐舒适性好;轮胎带束层与胎体间的粘合强度不高。 相似文献

There is widespread use of two main groups of adhesion promoters, the SRH-system and an organic cobalt salt. They are used either jointly or individually in the rubber compound for promotion and maintenance of good adhesion of rubber to brass-coated steel cord in radial tyres.
This paper describes the influence of anions associated with cobalt promoters on the adhesion energy and the pull-out force between brass-coated steel cord and rubber and their relationship to other relevant physical properties, under the influence of various environments which simulate tyre service conditions.
It is observed that incorporation of a cobalt promoter greatly enhances the adhesion energy and influences the Young's modulus and crosslink density of the rubber compound in a similar fashion. The study establishes the supremacy of boroacylate among the anions considering its overall good performance and the protection offered against various hostile environments. However, the benefits of the cobalt promoter is not realised with stearate ion. The results are explained on the basis of chemical stability of the promoter and the properties of the interfacial film and the compounds. 相似文献
