High-temperature-resistant and corrosion-resistant radar wave-absorbing composite material and preparation process thereof
The invention discloses a high-temperature-resistant and corrosion-resistant radar wave-absorbing composite material. The composite material is prepared from, by mass, 10 to 20 parts of nano-graphene,5 to 20 parts of a multi-walled carbon nanotube, 10 to 15 parts of nanometer nickel oxide, 10 to 15 parts of nanometer titanium dioxide, 15 to 20 parts of a ceramic matrix, 15 to 20 parts of a resinmatrix, 5-15 parts of a reinforcement and 100 to 200 parts of a solvent. The nano-graphene, the multi-walled carbon nanotube, the ceramic matrix and the reinforcement are jointly used as an absorbent,so that the absorption band range of electromagnetic waves is expanded, and the absorption rate is increased; meanwhile, due to the mixed arrangement of the ceramic matrix and the reinforcement, thetolerance temperature of the high-temperature-resistant stealth material is further increased; and the nanometer nickel oxide and the nanometer titanium dioxide increase the hardness, and meanwhile, the electromagnetic wave absorption rate of the high-temperature-resistant stealth material is improved.
本发明公开了一种耐高温耐腐蚀的雷达吸波复合材料，按质量份数计，包括纳米石墨烯，10‑20份；多壁碳纳米管，5‑20份；纳米氧化镍，10‑15份；纳米二氧化钛，10‑15份；陶瓷基体，15‑20份；树脂基体，15‑20份；增强体，5‑15份；溶剂，100‑200份。本发明中纳米石墨烯、多壁碳纳米管、陶瓷基体和增强体共同作为吸收剂，扩大对电磁波的吸收波段范围，增强吸收率；同时陶瓷基体和增强体的混合设置进一步提升耐高温隐身材料的耐受温度；纳米氧化镍和纳米二氧化钛增加硬度，同时提升耐高温隐身材料的电磁波吸收率。
