不同品种炭黑在载重子午线轮胎胎面胶中的应用

Application of Different Kinds of Carbon Black in Tread Compound of Truck and Bus Radial Tire

研究3种炭黑在载重子午线轮胎胎面胶中的应用。结果表明:炭黑EB262的分散性最差,胶料的门尼焦烧时间最长,交联密度最大,生热最高;炭黑HP130的分散性最好,胶料的正硫化时间最短,耐磨性能最好,生热最低,综合性能最佳;炭黑N134胶料的硫化特性、耐磨性能和生热介于炭黑EB262与炭黑HP130胶料之间。

The application of three kinds of carbon black in the tread compound of truck and bus radial tire was investigated.The results showed that,the dispersion of carbon black EB262 was the worst,the Mooney scorch time of the compound filled with carbon black EB262 was the longest,the crosslinking density was the largest and the heat build-up was the highest.The dispersion of carbon black HP130 was the best,the optimum curing time of the compound filled with carbon black HP130 was the shortest,the wear resistance was the best,the heat build-up was the lowest,and the comprehensive property was the best.The vulcanization characteristics,wear resistance and heat build-up of carbon black N134 filled compound were between those of carbon black EB262 and carbon black HP130 filled compounds.
