Abstract

With the development of rubber technology the requirements for rubber products are becoming more and more strict. Enhancing the interfacial bonding strength between vulcanized natural rubber (NR) and polyester fibers (PEF) has become our research goal. In the research described here the effect of rosin resin (RR) on the properties of NR/PEF was studied. Dynamic experiments were conducted within the strain range from 1 to 100% using a rubber process analyzer (RPA). The adhesive properties of the RR in the NR matrices with the PEF were further studied by the peel test, which indicated an enhancement of the bonding effect in the vulcanized NR-PEF composites. The failure modes of the mixtures following various aging conditions were studied by scanning electron microscopy (SEM). When 3phr of RR were added to the NR/PEF composite, the interfacial bonding strength between the rubber and fiber had the best value compare to samples with 0, 1, 2, 4 and 5phr. Our results indicated that RR used as a tackifier added to NR prior to vulcanization improved the bonding between vulcanized NR and the PEF.

摘要

随着橡胶技术的发展，对橡胶产品的要求越来越严格。提高硫化天然橡胶（NR）和聚酯纤维（PEF）之间的界面粘结强度已成为我们的研究目标。在这里描述的研究中，研究了松香树脂（RR）对NR / PEF性能的影响。使用橡胶过程分析仪（RPA）在1至100％的应变范围内进行了动态实验。通过剥离试验进一步研究了RR在NR基质中与PEF的粘合性能，这表明硫化NR-PEF复合材料的粘合效果得到了增强。通过扫描电子显微镜（SEM）研究了混合物在各种老化条件下的破坏模式。当将3phr的RR加入NR / PEF复合材料时，与0、1、2、4和5phr的样品相比，橡胶和纤维之间的界面粘合强度具有最佳值。我们的结果表明，在硫化之前将RR用作增粘剂添加到NR中，可以改善硫化NR和PEF之间的结合。
