摘要
研究了白炭黑对室温硫化(RTV)硅橡胶包覆层材料力学性能、粘接性能和烧蚀性能的影响。结果表明,白炭黑是硅橡胶包覆层材料较为理想的补强填料。随着白炭黑用量的增加,它能够提高硅橡胶的拉伸强度、伸长率和粘接强度,但是却使氧乙炔线烧蚀率增加,耐烧蚀性能变差。
The effect of silica aerogel (SiO 2) on the mechanical and bonding strength and ablativity of room temperature vulcanized (RTV) silicone rubber used for inhibiting of solid rocket propellants were investigated. The results show that SiO 2 is an effective reinforce filler. With the increase of SiO 2 content, the tensile strength of silicone rubber and the bonding strength of silicone rubber coated HMX CMDB propellant or Al RDX CMDB propellant increase, but the ablation resistance of silicone rubber decreases.
