High-acceleration aging test device and method for high polymer material

A high-acceleration aging test device for a high polymer material, comprising an ultraviolet light reflection system (1), a sample temperature control system (2), a sun tracking system (3), a multi-environmental factor coordination control system and the like. The ultraviolet light reflection system (1) is of a spherical concave shape, and can realize efficient light condensing. The surface of a reflector (13) in the ultraviolet light reflection system (1) adopts a combined reflecting film. The reflecting film has high ultraviolet reflectivity, large bandwidth and high durability. The sample temperature control system (2) controls the temperature by means of a temperature control mechanism (23), and the temperature control effect is better. Moreover, also disclosed is a method for accelerating aging by using the device. The accelerated aging rate of the device is as high as 30-50 times by tracking the sun and condensing light, and support is provided for rapid aging evaluation of the high polymer material.
