摘要
考察硫黄预分散母料在轮胎胎面胶中的应用。结果表明:与粉末硫黄相比,硫黄预分散母料在胶料中的分散性较好;与片状硫黄预分散母料相比,粒状硫黄预分散母料与胶料接触面积较大,在胶料中的分散性较好。硫黄预分散母料可以替代粉末硫黄在胎面胶中使用,减小粉末硫黄因分散不良产生的轮胎次品率,提高轮胎质量。
In this study, the application of pre-dispersed sulfur masterbatch in the tire tread compound was investigated. Compared with direct use of powder sulfur, with the pre-dispersed masterbatch, the dispersion of sulfur in the ifnal compound was improved. With granular masterbatch the sulfur dispersion was better than that using platelike masterbatch. It was demonstrated that using pre-dispersed masterbatch, the defective rate of the tire due to poor sulfur dispersion was reduced and the tire quality was improved.
