摘　　要：介绍了木塑复合材料(WPC)常用的老化测试方法及测试过程中的影响因素。自然大气老化法是评价木塑复合材料使用寿命最直接、最可靠的方法,但其耗时长、环境条件无法控制。人工加速老化试验虽能快速得到老化结果,但仍需以自然老化的结果作为参考,以保证加速老化测试的真实性。This paper introduces the commonly-used aging test methods of WPC and the influencing factors in the test process.The natural atmosphere aging method is the most direct and reliable method to evaluate the service life of WPC,but it's time-consuming and environmental conditions can not be controlled.Although the artificial accelerated aging test can get the aging result quickly,the natural aging results are still needed as reference to ensure the authenticity of accelerated aging testing.

关 键 词：木塑复合材料 自然老化 人工加速老化
