| 中文摘要: |
| 介绍了高速铁路和公路用声屏障橡胶件的结构设计、配方研究以及标准。确定了4种截面结构,其中解耦橡胶垫为中空-实心复合多孔结构,有利于降低因脉动力和噪音的耦合对声屏障的破坏作用。采用可控长链支化三元乙丙橡胶与充油三元乙丙橡胶并用,硫化胶兼有良好的物理性能和加工性能。在石蜡油的基础上添加少量非石油基耐寒增塑剂,提高了耐寒性能。依据本研究的试验结果,制订了国家标准(GB/T30649-2014)。优选配方的产品性能全部符合标准要求。 |
| 英文摘要: |
| Structual design , formulation test and standard of rubber articles for sound barrier on the high-speed railway and the highway was introduced. It confirmed four cross-sectional structure in which a decoupling rubber gasket with hollow - solid composite porous structure, this structure help to reduce the risk of damage on noise barriers due to the combined effect of impulsive force and noise. Use blends of CLCB-EPDM and oil-extended EPDM , the vulcanizates both good physical properties and processability. Add a small amount of non-petroleum-base low-temperature resisting plasticizer on the basis of paraffin oil to improve the cold resistance.According to the test results of this study to establish a national standard (GB/T30649-2014). Products by the preferred formulation all meet the standards. |
