Abstract

A high molecular material ultraviolet radiation aging device. The invention relates to the high molecular material ultraviolet radiation aging device which solves problems of poor utilization efficiency of a light source in a photo-aging device and complex structure of the device in the prior art. The aging device is composed of a fluorescent ultraviolet light tube, a light head, a coating barrel and two light tube supporting parts. The coating barrel is formed by hinging a left semi-cylinder and a right semi-cylinder to each other. The light tube supporting parts are respectively buckled onto the two opening ends of the coating barrel. A supporting bracket is arranged on internal circumference surfaces of the light tube supporting parts. The supporting bracket is attached to the fluorescent ultraviolet light tube. The light head is fixed to the supporting parts. A plurality of radiation degree observing holes are formed in the coating barrel. The ultraviolet radiation aging device requires fewer assemblies and is simple in structure. By means of a barrel column structure of the coating barrel, almost light emitted by the light tube can be absorbed by a tested material so that a light source utilization rate is high.

Description

technical field [0001] The invention relates to an ultraviolet aging test device for polymer materials, in particular to an aging device for performing artificial ultraviolet accelerated aging tests on asphalt materials, paint materials, coating materials and the like. Background technique [0002] How to evaluate the aging of materials is a problem that people have been paying close attention to all the time. Currently, there are mainly two types of methods: natural atmospheric exposure and artificial accelerated aging. Natural atmospheric exposure is the most authentic method to evaluate the aging characteristics of polymers, but natural atmospheric exposure has disadvantages such as long aging period, uncontrollable environmental factors, and poor repeatability of test results. Therefore, on the one hand, new natural atmospheric exposure methods are constantly invented; on the other hand, artificial accelerated aging tests have been more and more widely used. In fact, a...
