摘要
研究亚甲基给予体HMMM和间苯二酚-甲醛树脂(简称间甲树脂)SL-3020LFR并用比对半钢子午线轮胎带束层胶性能的影响。结果表明:随着HMMM/间甲树脂SL-3020LFR并用比的增大,胶料的F_(max)-F_(L)增大,焦烧时间和硫化时间均呈延长趋势;胶料的定伸应力略增大、老化后胶料的拉伸强度和拉断伸长率降幅增大;60℃下胶料的损耗因子先增大后减小;热空气、蒸汽和盐雾老化抽出后的钢丝帘线无露铜现象,钢丝表面均附有黑色胶料。综合来看,HMMM/SL-间甲树脂3020LFR并用比为1.6时,不同硫化和老化条件下胶料与钢丝帘线的粘合性能较佳。
The effect of the blend ratio of methylene donor HMMM and resorcinol-formaldehyde resin(referred to as RF resin)SL-3020LFR on the properties of belt compound in steel-belted radial tire was studied.The results showed that,with the increase of the HMMM/RF resin SL-3020LFR blend ratio,the F_(max)-F_(L) of the compound increased,and both the scorch time and vulcanization time tended to be prolonged.The modulus of the compound slightly increased,and the tensile strength and elongation at break of the compound decreased more after aging.At 60℃,the loss factor of the compound first increased and then decreased.After being aged in hot air,steam and salt spray,the extracted steel cord was free of copper leakage and the surface of the steel wire was coated with black compound.Overall,when the HMMM/RF resin SL-3020LFR blend ratio was 1.6,the adhesive performance between the compound and steel cord was better under different curing and aging conditions.
