摘　　要：针对SUV车型铝制行李架配件越来越广泛的使用,对铝制行李架耐酸碱工艺提出了更高的要求。为解决高光铝材耐酸pH 1.0,耐碱pH 13.5和耐盐雾的性能问题,本文采用多封闭层方法,研究了不同封闭工艺对耐酸碱测试的影响。结果表明,在多层封闭条件下,采用冷封+热封的方法,在提高冷封和热封的工艺时间后,可以满足耐pH 1.0,pH 12.5和耐盐雾的实验要求的同时,进一步满足pH 13.5的高耐碱标准,达到了主流主机厂对汽车零部件的更高的要求。In view of the wide use of SUV aluminum luggage rack accessories,higher requirements are put forward for the acid and alkali resistance process of automobile aluminum luggage rack.In order to solve the performance problems of acid resistance pH 1.0,alkali resistance pH 13.5 and salt spray resistance of high gloss aluminum material,the influences of different sealing processes on acid and alkali resistance test are studied by using multi sealing layer method.The results show that under the condition of multi-layer sealing,the method of cold sealing combined with hot sealing can meet the experimental requirements of pH 1.0,pH 12.5 and salt spray resistance,and further meet the high alkali resistance requirements of pH 13.5 after increasing the process time of cold sealing and hot sealing,and meet the higher requirements of mainstream main engine manufacturers for automobile parts.
