摘　　要：以聚碳酸酯(PC)为基体材料,加入自制的激光吸收剂VI530和IR1060,并在基材表面镀上多层激光反射膜,制备出了能够同时对紫外光区、可见光区和红外光区的多个波长激光起到有效防护作用的激光防护PC材料。研究结果表明,在PC材料中加入质量分数为0.01%的VI530和0.05%的IR1060,并在PC材料表面镀23层激光反射膜后,所制得的激光防护材料对多个波长的激光都具有很好的防护性能。在355nm,532nm,1064nm等多个波长处的透过率都低于0.01%(光学密度D>4)。可见光区的白光平均透过率为13.7%,抗冲击强度为53.3kJ/m2,抗弯强度为118MPa。是一种高性能的激光防护材料。The laser protective material was prepared by using PC as substrate,laser absorption VI530 and IR1060 as function additives,plated multi-layer reflective coatings on its surface,which could protect effectively from multi-wavelength laser.As a result,after adding 0.01%（mass percent） VI530 and 0.05%（mass percent） IR1060 into PC,and plating 23-layer reflective coatings on the surface of PC,the laser protection ability of the laser protective material was very well.The transmittance of the laser protective PC material was lower than 0.01% at the wavelength of 355nm,532nm,1064nm and so on,the optical density D〉4.At the mean time,the average transmission ratio of visible light was 13.7%,the impact strength of the material was 53.3kJ/m^2,and the bending strength was 118MPa.All the results were attained that the material was a very well laser protective material.
