Abstract

The invention discloses an accelerated aging test method for a polymer material xenon lamp in an environment simulating a typical xerothermic climate of China. The accelerated aging test method comprises: (1) selecting the test equipment: selecting a water-cooled rotary drum xenon lamp aging test box, adopting a xenon arc lamp as a test light source, wherein light source inner/outer filters are made of BORO/BORO borosilicate glass material ; (2) preparing samples; (3) setting test parameters: light intensity: 0.60 +/- 0.05W/m2@340nm, test box body temperature: 50 +/- 3 DEG C, blackboard temperature: 70 +/-3 DEG C, relative humidity: 20 +/- 3%, continuous illumination, no lamp turned off, and no spray; (4) determining the test time: calculating the test time by combining the total amount ofultraviolet radiation received by the sample in the service area according to the set light intensity; (5) performing the test: performing the aging test according to the aging test operation protocol. The accelerated aging test method for the polymer material xenon lamp in the environment simulating typical xerothermic climate of China can be used for detecting the durability of high polymer materials and articles in the typical xerothermic climate environment of China.

Description

technical field [0001] The invention belongs to a polymer material aging test method, and specifically refers to a polymer material xenon lamp accelerated aging test method for simulating a typical dry and hot climate environment in my country. Background technique [0002] When exposed to the natural environment, polymer material products will age due to environmental factors such as sunlight, heat, and water, and failure phenomena such as fracture, deformation, stickiness, and discoloration will occur, shortening the service life of the product. [0003] To study the environmental durability and service life of polymer materials, two methods, natural aging test and artificial accelerated aging test, are usually used. The research results show that the main climate and environmental factors affecting the aging of polymer materials are solar radiation, temperature and water; for large For most polymer materials, in a variety of climatic environments, the relatively harshest ...
