摘要
研究粘合树脂PN760在半钢子午线轮胎带束层胶中的应用。结果表明:在带束层胶中以粘合树脂PN760替代R-80/B-20-S并用体系,并适当增大促进剂用量,胶料的门尼焦烧时间和t90相当,硫化胶的拉伸强度和拉断伸长率增大,粘合性能提高;成品轮胎的高速和耐久性能均超过企业标准要求,轮胎带束层间剥离强度增大,覆胶情况良好。
The application of adhesive resin PN760 in the belt compound of steel belted radial tire was investigated. The results showed that, by using PN760 to replace R-80/B-20-S blend system and increasing the addition level of accelerator properly in the belt compound,the Mooney scorch time and t90 of the compound changed little,the tensile strength and elongation at break of the vuleanizates increased ,and the adhesion property was improved. The high speed and endurance performance of the finished tire exceeded the requirements of national standards, the peel strength between belts increased, and the molding of belt compound was good.
