Abstract: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/m2,and the bending strength was 118MPa.All the results were attained that the material was a very well laser protective material.
