几种粘合促进剂在全钢子午线轮胎胎体中的应用

Application of Several Adhesion Promoters in Carcass of All-steel Radial Tire

研究间苯二酚、间甲树脂、酚醛树脂3种粘合促进剂在全钢子午线轮胎胎体中的应用。结果表明:间苯二酚硫化胶的邵尔A型硬度和定伸应力较大,酚醛树脂和间甲树脂硫化胶的撕裂强度和拉断伸长率较大;酚醛树脂硫化胶与钢丝帘线的初始抽出力较高,老化后,间苯二酚和间甲树脂硫化胶与钢丝帘线的抽出力和抽出力保持率较高;酚醛树脂硫化胶压缩生热和60℃时的损耗因子明显高于间苯二酚和间甲树脂硫化胶。在实际生产中,应根据原料特性与应用性能调整配方与优化工艺,以获得最佳的综合性能。

The application of three kinds of adhesion promoters,resorcinol,resorcinol resin,and phenolic resin,in the carcass of all-steel radial tires was studied.The results showed that the Shore A hardness and modulus of the vulcanizate using resorcinol were higher,while the tear strength and elongation at break of the vulcanizate using phenolic resin and resorcinol resin were higher.The initial pull-out force of the vulcanizate using phenolic resin with steel cord was relatively high,and the pull-out force and its retention rate of the vulcanizate using resorcinol and resorcinol resin with steel cord were relatively high after aging.The compression heat build-up and loss factor at 60℃of the vulcanizate using phenolic resin were significantly higher than those of the vulcanizate using resorcinol and resorcinol resin.In actual production,formula adjustments and process optimization should be made based on the characteristics of raw materials and application performance to obtain the best comprehensive performance.
