Abstract

The invention discloses a climate environment simulating design method for an accelerated aging test of a xenon lamp made from a high molecular material. The method comprises the following steps: (1)monitoring and analyzing climate environment conditions of some region where a high molecular material aging test is to be carried out; (2) designing at least three groups of accelerated aging test parameters of an xenon lamp based on a principle that the parameters are similer to the climate environment condition data of the region; (3) selecting a material, the structural property of which is similar to the to-be-tested high molecular material, as a reference material, and obtaining the accelerated aging test data of the xenon lamp of the reference material; (4) acquiring data of a natural atmospheric exposure test of the reference material; and (5) comparing the natural atmospheric exposure test of the reference material with the accelerated aging test data of the xenon lamp and determining the accelerated aging test condition, the relevance of which to the natural atmospheric exposure test is the best. The method is suitable for a high molecular material aging test.

Description

technical field [0001] The invention relates to a design method of a xenon lamp accelerated aging test, in particular to a design method of a polymer material xenon lamp accelerated aging test that simulates a climate environment. Background technique [0002] Due to the influence of the environment during use or storage, such as light, heat, oxygen, humidity, stress, chemical corrosion, etc., the performance of polymer materials will be deteriorated or lost. This phenomenon is called the aging of polymer materials. The xenon lamp accelerated aging test is an important test method for studying the aging behavior of polymer materials, and is widely used in aging tests and researches of various polymer materials. [0003] Among the existing xenon lamp accelerated aging test standards, such as GB / T 1865-2009, ISO 11341-2004 and SAE-J2527-2004, some can provide different test methods for different materials and products, but few Accelerated aging test standards for different cl...
