空调白色面板ABS材料光老化研究

A study on light-aging resistance of air conditioner white panel materials of ABS

采用家电行业常用的人工加速光老化实验方法,对目前空调面板常用的白色ABS材料进行了光老化研究,一方面比较了色母料和改性料方案的耐光老化性能,另一方面比较了常用光老化试验方法严酷程度。研究表明:改性料方案耐光老化性能优于色母料;采用氙灯光老化(X)、紫外光老化UVA(ZA)和紫外光老化UVB(ZB)等三种常用试验方法时,实验样品对光老化的响应程度依次为:UVB(ZB)测试>UVA(ZA)测试>氙灯(X)测试。

The light artificial accelerated aging test method commonly used in the home appliance industry is utilized to carry out light aging research on the white ABS material which commonly used in air conditioner panel.On the one hand,the light aging resistance of the color masterbatch material and the modified material are compared;on the other hand,the severity of the commonly used light aging test method was compared.The results show that the light aging resistance of the modified material is better than that of the color masterbatch material.when Xenonarc lamp aging(x),Fluorescent aging UVA(ZA)and Fluorescent lamp aging UVB(ZB)are used,the response degree of the experimental samples to light aging is as follows:UVB(ZB)test>UVA(ZA)test>xenon lamp(x)test.
