Abstract

Due to the influence of elevator pit environment, polyurethane buffer for elevator is prone to aging, resulting in its buffer performance failure. In this paper, the accelerated aging test of polyurethane buffer for elevator was carried out at different time. The mechanical properties and mass changes of the samples after different aging time were analyzed. The results show that the aging time has an obvious effect on the properties of polyurethane materials.
