摘　　要：采用聚碳酸酯为基材,掺杂激光吸收剂制备了防530nm和1060nm波长激光的防护材料,通过对加工温度和混合料在料筒中停留时间的研究,确定了材料的加工温度为280℃,混合料在料筒中的时间为3min,确定了防护材料的加工工艺条件,并对其光学密度、激光防护能量、可见光透过率和抗冲击强度进行了测试。结果表明防护材料在530nm和1060nm波长的光密度大于4,其防激光能量达150mJ,可见光透过率为17%,抗冲击强度高,完全可以满足一般激光防护材料的要求。By the study of processing temperature and time mixed material remaining in the reel, the processing technology was determined. The material was put on a UV-Vis-NIR Scanning Spectrophotometers and tested. The re.suit showed that optical densities of material in 530nm and 1060nm wavelength were more than four, transmission of visible light of the material was 17%, laser protective energy run up to 150mJ and the anti-impact strength was enough high. So the laser protective material was satisfied with the general requirement.
