Preparation and Performance of High Durable Laminated Bearings
Laminated bearings is widely used as important connecting components in bridges,and it's durability has received attention.Based on the material characteristics of natural rubber and ethylene propylene diene monomer rubber,several compound formulations with different ratios are designed.Through testing and evaluating their tensile strength,elongation at break,hot air aging,and ozone aging resistance,one of the formulations is selected as the high durability rubber for research,namely S25-10.Its performance when used as the laminated bearing materials is studied through experiments.The results show that,the high durability plate rubber bearing has good mechanical properties and meets the technical requirements of bridge engineering.In terms of durability,its hot air aging and ozone aging resistance are more prominent than natural rubber laminated bearings,which can further improve the durability and service life of plate type rubber bearings.
