摘　　要：从丙烯腈-丁二烯-苯乙烯共聚物(ABS)板材的成型过程、产品结构以及微裂纹分析了覆革ABS吸塑件应力开裂行为产生的原因。结果表明,提高ABS板材的韧性,减小回料比例以及退火处理可改善吸塑件应力开裂情况,产品结构复杂和微裂纹也是造成吸塑件应力开裂的原因。相应地提出了解决问题的方法,为ABS吸塑件的安全使用提供了科学依据。The causation on the stress cracks of ABS sheet covered by covering leather was analyzed from molding process of the ABS sheet, product structures and microcrack. The results show that improving the toughness of the ABS sheet, reducing the waste percentage,and annealing treatment can improve stress cracks of absorption parts. The reasons of stress cracks are also from complex structure and microcrack of the product. A method of solving problem is introduced accordingly, and the scientific reference is pro- vided for the application of ABS absorption parts in safety.
