摘　　要：目的通过双层涂层材料结构,获得性能优良的适用于舰船甲板的耐烧蚀涂层。方法以环氧树脂为底层基体材料,加入不同的助剂和填料,再以莫来石为表层基体材料,加入不同的耐火原料,制备出一种适用于舰船甲板的耐烧蚀涂层。通过附着力和剪切力测试对耐烧蚀涂层的底层进行性能研究,通过常温抗折强度、常温耐压强度、耐火度、导热系数、热膨胀系数测试对耐烧蚀涂层的表层进行性能研究,通过耐盐雾性能、老化性能、耐冲击性能、隔热性能和耐烧蚀性能测试对耐烧蚀复合涂层进行性能研究。最后,考察了耐烧蚀涂层的涂抹工艺。结果该耐烧蚀涂层材料底层附着力为24.03 MPa,剪切力为7.8 MPa,表层耐火度为1580℃,常温抗折强度为9.1 MPa,耐压强度为65.7 MPa,导热系数为0.762 W/(m·K)。涂层具有良好的耐盐雾性能、老化性能、耐冲击性能、隔热性能和耐烧蚀性能。结论该耐烧蚀涂层材料可用于舰船甲板表面的外防护,并且具有良好的涂抹施工性。The work aims to make an ablation-resistant coating with excellent properties for ship deck from a double layer coating material structure. With epoxy resin as bottom base material and mullite as surface base material, a kind of ablation-resistant coating material for ship deck was prepared by adding several adjuvants and filler as well as various refractory raw materials. Properties of the ablation-resistant coating bottom were studied by testing adhesive force and shear force. Properties of the ablation-resistant coating surface were studied by testing modulus of rupture, cold crushing strength, refractoriness, thermal conductivity and coefficient of thermal expansion. Properties of the ablation-resistant composite coating were studied by testing neutral salt spray resistance, artificial weathering-resistant property, impact resistance, heat-insulating property and ablation resistance. At last, smear process of the ablation-resistant coating was investigated. Adhesion of the coating bottom was upto 24.03 MPa, shear force 7.8 MPa, surface coating refractoriness up to 1580 ℃, modulus of rupture 9.1 MPa, cold crushing strength 65.7 MPa and thermal conductivity 0.762 W/（m·K）. The coating material possesses better neutral salt spray resistance, artificial weathering-resistant property, impact resistance, heat-insulating property and ablation resistance. The developed ablation-resistant coating material can be used for external protection of ship deck surface, and it exhibits excellent smear application property.
