The adhesion property between rubber compounds containing different types of adhesion promoters (resinous adhesion promoter (containing both methylene donor and methylene acceptor), cobalt salt and zinc borate) and different loading amounts of sulfur and brass-plated steel cords was investigated to understand the effect of sulfur loading in the rubber compounds on their adhesion characteristics to the brass-plated steel cords. The adhesion property of the rubber compounds to brass-plated steel cords was largely dependent on both the type of adhesion promoter and the loading amount of sulfur in the rubber compounds. The pull-out force of adhesion samples increased significantly with increasing loading amount of sulfur in the rubber compounds containing resinous adhesion promoter, whereas it decreased slightly with increasing loading amount of sulfur in rubber compounds containing cobalt salt or zinc borate. In humidity aging, the best adhesion retention was observed in the rubber compound containing zinc borate and low loading of sulfur. Regardless of the type of adhesion promoter, adhesion retention after thermal aging treatments improved with increasing loading amount of sulfur in the rubber compounds. The adhesion property was interpreted in terms of the interphases formed between the rubber compounds and the brass-plated steel cords as studied using Auger electron spectroscopy. 相似文献

采用正交设计法和对比试验法,考察了硫黄、氧化锌、促进剂、炭黑以及某些工艺条件对胶料与镀铜钢丝帘线粘合力的影响。结果表明,硫黄品种对粘合力的影响不大;氧化锌用量增大,粘合力增大;用1.0份促进剂CZ时的粘合力大于用1.3份促进剂DZ;使用高结构炭黑可增大粘合力;胶料的混炼方法和硫化时间对粘合力的影响较大。 相似文献

对硼酰化钴MC23(钴质量分数为23%)用量(06~16份)对橡胶与钢丝帘线粘合性能的影响进行研究。采用的基本配方为:NR1000;炭黑N326620;芳烃油80;氧化锌90;硬脂酸05;防老剂402020;不溶性硫黄IS702060;促进剂DZ10;粘合剂RS35;粘合剂A23;沉淀法白炭黑50。结果表明,随着钴盐用量的增大,在未老化、热空气老化及盐水老化条件下,胶料与钢丝的粘合强度有所提高;在湿热老化条件下,粘合强度由于热量和湿气的交互作用而发生较大幅度的下降,但钴盐用量在10份时粘合强度的下降为最小。综合胶料初始和老化后的应力应变性能和粘合强度,以10份钴盐用量为最佳。 相似文献

The adhesion between tetrachlorobenzoquinone (TCBQ)-loaded rubber compound and brass-plated steel cord was studied to understand the role of TCBQ as an adhesion promoter. With loading of TCBQ in the rubber compound the cure rate became slow, but the change in physical properties was not significant. An improvement of the adhesion was obvious with low loading of TCBQ at the range of 0.5 phr while an adverse effect was observed with high loading at 2 phr. The addition of TCBQ for the improvement of adhesion has a greater effect before aging because TCBQ contributes to form a large surface area of copper sulfide via accelerated copper diffusion into the rubber bulk. However, higher TCBQ loading as well as longer aging time leads to a great extent of copper migration into the rubber and excess growth of zinc oxide layer, resulting in decreased adhesion. The adhesion interphase before aging, between a thin brass film and a rubber compound, investigated using AES showed no difference except that sulfur increased with increasing TCBQ loading. On the other hand, the adhesion inter-phase was changed after humidity aging. The copper content decreased at the adhesion interphase while it increased in the rubber layer with increasing addition of TCBQ. 相似文献
