Poly(ethylene terephthalate) (PET) cords are usually coated with epoxy and/or isocyanate solutions (like methylene diphenyl diisocyanate [MDI]) before resorcinol‐formaldehyde‐latex (RFL) to increase the adhesion efficiency of RFL. In this article, the addition of glycidyl polyhedral oligomeric silsesquioxane (GPOSS) as an adhesion promoter to PET cord was investigated for reinforcing PET cord/rubber interfacial adhesion. Therefore, GPOSS treated PET cords (GPOSS + MDI + RFL) were prepared in different process conditions like different GPOSS ratios and oven curing times and then vulcanized with rubber. RFL, GPOSS + RFL, MDI + RFL, and commercial epoxies treated PET cord samples were also prepared for comparison with GPOSS+MDI + RFL treated PET cord. The thermal, mechanical, and morphological properties of the treated PET yarn and their composites with rubber were investigated. It was seen that in the GPOSS coated PET yarns increased the stiffness and no change was observed in the tensile strength of the PET yarns. It was determined that the utilization of GPOSS in the PET cord improved the adhesion of the cord to rubber when compared with other treated PET cords via H‐adhesion and strip peel adhesion tests. Especially, since adhesion values give better results than commercially used epoxies, GPOSS as an adhesion promoter can be recommended in the rubber industry.

通过使用缩水甘油基POSS改善聚酯线和橡胶之间的粘合力

聚对苯二甲酸乙二醇酯（PET）线通常在间苯二酚-甲醛-乳胶（RFL）之前涂上环氧和/或异氰酸酯溶液（如亚甲基二苯基二异氰酸酯[MDI]），以提高RFL的粘合效率。在本文中，研究了将缩水甘油基多面体低聚倍半硅氧烷（GPOSS）添加为PET帘线的粘合促进剂，以增强PET帘线/橡胶的界面粘合力。因此，经过GPOSS处理的PET帘线（GPOSS + MDI + RFL）是在不同的工艺条件（例如不同的GPOSS比率和烤箱固化时间）下制备的，然后用橡胶硫化。还准备了RFL，GPOSS + RFL，MDI + RFL和商业环氧树脂处理过的PET帘线样品，以便与GPOSS + MDI + RFL处理过的PET帘线进行比较。热，机械，研究了经处理的PET纱线及其与橡胶的复合材料的形态学性能。可以看出，在GPOSS涂层的PET纱线中，刚度增加了，而PET纱线的拉伸强度没有变化。通过H粘附力和剥离剥离粘附力测试，与其他经过处理的PET绳索相比，可以确定在PET绳索中利用GPOSS可以提高绳索与橡胶的粘合力。特别是，由于粘合力值比市售的环氧树脂提供更好的结果，因此在橡胶工业中建议使用GPOSS作为粘合促进剂。通过H粘附力和剥离剥离粘附力测试，与其他处理过的PET绳索相比，可以确定在PET绳索中使用GPOSS可以提高绳索与橡胶的粘合力。特别是，由于粘合力值比市售的环氧树脂提供更好的结果，因此在橡胶工业中建议使用GPOSS作为粘合促进剂。通过H粘附力和剥离剥离粘附力测试，与其他经过处理的PET绳索相比，可以确定在PET绳索中利用GPOSS可以提高绳索与橡胶的粘合力。特别是，由于粘合力值比市售的环氧树脂提供更好的结果，因此在橡胶工业中建议使用GPOSS作为粘合促进剂。
