[0002] The TPEE aging resistance test device is a test equipment specially used to evaluate the aging performance of thermoplastic polyester elastomer materials under long-term use or specific environmental conditions. The device usually includes key components such as a heating system, a control system, and a sample fixture. By simulating harsh environments such as high temperature and high humidity, the test device can accelerate the aging process of TPEE materials and monitor the performance changes of the material during the aging process in real time. These performance changes include mechanical properties, thermal properties, elastomer properties and other aspects. These performance changes can be accurately recorded and evaluated through the data recording system. The TPEE aging resistance test device provides important technical support for material research and development, quality control and performance evaluation, ensuring that TPEE materials have good aging resistance in practical applications.

[0003] During the implementation of this application, it was found that the technology has the following problems: the water resources of the existing TPEE aging resistance test device cannot be recycled, resulting in unnecessary consumption of water resources, which is not conducive to environmental protection and cost control. At the same time, the ultraviolet lamp group cannot irradiate the surfaces of both sides of the TPEE, and the irradiation is not comprehensive, resulting in inaccurate aging tests on both sides of the TPEE material.

[0004] Therefore, a TPEE aging resistance testing device is proposed. Utility Model Content
