Novel aging tester for plastic granules

The utility model provides a novel aging tester which is used for plastic granules and is long in service life. The aging tester comprises a test box and a control box, wherein a front door is arranged on the front side of the test box, an explosion-proof window and a handle are arranged on the front door, an exhaust port is arranged on the test box, a push-and-pull shading plate is arranged on the explosion-proof window, an explosion-proof light-transmitting mirror is arranged in the center of a heat-insulating plate, the heat-insulating plate divides the test box into an upper ultraviolet emission chamber and a lower sample chamber, an ultraviolet lamp is arranged inside the ultraviolet emission chamber, a reflection cover is arranged on the outer side of the ultraviolet lamp, and a water receiving tank is mounted at the bottom of the sample chamber through a rolling shaft. According to the aging tester, the test box is divided into the ultraviolet emission chamber and the sample chamber by the heat-insulating plate, so that an ultraviolet aging test can be performed while a high-temperature aging test is performed; ultraviolet rays emitted by the ultraviolet lamp can be reflected by the reflection cover on the outer side of the ultraviolet lamp, so that the intensity of the ultraviolet rays is enhanced, and the loss of the ultraviolet rays is also avoided.
