摘　　要：硼酚醛树脂的高温稳定性和耐烧蚀性能较好,在抗激光烧蚀领域有巨大的应用潜力。以硼酚醛树脂为基体,以碳化硅/二氧化锆/纳米炭黑为无机改性填料,制备新型硼酚醛树脂基激光防护复合涂层,并对其抗激光烧蚀性能进行研究。结果表明:复合涂层具有良好的抗激光烧蚀性能,经平均功率为500 W/cm~2的高斯光斑激光烧蚀15 s后,涂层整体完好,质量烧蚀率仅为0.011 g/s,同时基体材料背表面无损伤,最高背温仅为230.4℃;无机填料在激光烧蚀过程中发生氧化、相变等反应,起到消耗能量、遮蔽激光、阻氧及隔热等作用,能提高硼酚醛树脂涂层的抗激光烧蚀性能。Boron-phenolic resin(BPR)has good high-temperature stability and anti-ablation resistance,and represents a great application potential in the field of anti-laser ablation.A new type of laser protection composite coating was prepared in the study,with boron-phenolic resin as base material and with silicon carbide/zirconium dioxide/nano carbon black as inorganic filler material.The anti-laser ablation resistance of the prepared coating was studied.The results show that the composite coating has a good anti-laser ablation resistance.After the Gaussian-spot laser ablation under an average power of 500 W/cm~2 for 15 s,the coating remains intact,and the mass ablation rate is only 0.011 g/s.The back-surface of the substrate is not damaged,and the maximum back-surface temperature is only 230.4 ℃.Oxidation,phase transformation and other reactions occur during laser ablation of inorganic fillers,which play a role in laser energy consumption,shielding laser ablation,oxygen resistance,heat insulation,and effectively improving the anti-laser ablation resistance of the boron-phenolic resin coating.
