摘　　要：研究粘合树脂KOTA在全钢载重子午线轮胎带束层胶中的应用,并与间苯二酚-甲醛粘合树脂进行对比。结果表明:在全钢载重子午线轮胎带束层胶中用粘合树脂KOTA等量替代间苯二酚-甲醛粘合树脂,胶料的门尼粘度略大,焦烧时间稍短,FL和Fmax略高,硫化速率变化较小;硫化胶的密度、硬度、定伸应力、拉伸强度、撕裂强度和钢丝帘线抽出力相差不大;胶料在混炼、压延过程中的刺激性气味基本消失,烟雾量明显减小,工艺性能良好;成品轮胎的耐久性能相当;胶料成本降低。The application of adhesive resin KOTA in the belt compound of truck and bus radial tire was studied and compared with resorcinol formaldehyde adhesive resin. The results showed that,by using the same amount of adhesive resin KOTA to replace the resorcinol formaldehyde adhesive resin in the belt compound of truck and bus radial tire,the Mooney viscosity of the compound was slightly higher,the scorch time was slightly shorter,FL and Fmax were slightly higher,and the curing rate changed little. In addition,the density,hardness,modulus,tensile strength and tear strength of the vulcanizates had little difference,and the steel cord pull-out force was at the similar level as well. However,during the process of mixing and calendering,the pungent odor disappeared,the smoke amount decreased significantly,the processing property of the compound was good,the durability of finished tire was equivalent to that with original formulation,and the compound cost was reduced.
