采用Nd-YAG红外激光打标机，在不同参数设计下对车用聚丙烯复合材料进行红外激光打标，考察了各工艺参数对材料激光打标性能的影响，采用色差变化(ΔE)和明暗度变化(ΔL)定量地表征车用聚丙烯复合材料的激光打标效果，筛选出了最佳工艺参数。结果表明，步长、电流和频率是影响车用聚丙烯材料激光打标效果的主要参数，要获得理想的打标效果，参数选择需要控制在合适的范围之内。对于本实验车用聚丙烯复合材料而言，理想的红外激光打标工艺参数为电流14～15 A、频率1～3 kHz、步长0.005 mm。

With different design parameters,infrared laser marking on vehicle polypropylene material was performed by using Nd-YAG 1 064 nm laser marking machine. The effect of technological parameter on infrared laser marking property of polypropylene composite for automobile was investigated. The laser marking performance of polypropylene blend was quantificationally evaluated by color aberration index (ΔE) and shading changes(ΔL),and the optimum technological parameters were selected. The result indicate that the current intensity,step length and frequency are the main influence factors on laser marking effect. The technological parameters should be adjusted properly for the better performance of laser marking. For polypropylene blend researched in this article,the current intensity of 14~15 A,step length of 1~3 kHz and frequency of 0.005 mm are the ideal parameters for infrared laser marking.
