摘要： 研究了紫外光(UV)固化涂料在喷涂及光固化过程中对高抗冲聚苯乙烯(PS-HD)力学性能的影响。结果表明:PS-HD的弯曲强度、弯曲模量略有上升，拉伸强度的变化率为一8.2，冲击强度的变化率为一11.0，而断裂伸长率的变化率为一85. 1%;力学性能变化是底漆中复合溶剂和非溶剂组分、UV固化涂料中光引发剂以及固化过程中紫外光照射等因素共同引起的应力开裂、降解、交联等作用的结果;紫外光照射次数对PS-HD工的断裂伸长率影响比较明显。

Abstract: A coating was applied on the surface of PS-HI samples and cured with ultraviolet irradiation.The changes in the mechanical properties of PS-HD were studied. Compared with the properties of neat PS-HD, the flexural strength and flexural modulus slightly increased, however, the tensile strength, impact strength, and elongation at break decreased by 8 .2%，11.0%，and 85.1%，respectively. Such deterioration in properties may be caused by stress cracking, degradation，crosslinking, and so on. the elongation at break was most sensible to the irradiation times.

Key words: ultraviolet light curable coating, high impact polystyrene, mechanical property
