At present, the flexible heat-resistant materials comprise nitrile rubber, ethylene propylene diene monomer rubber, silicone rubber and polyphosphazene elastomers. The nitrile rubber has alkene reaction activity, low decomposition rate, strong binding power and excellent ablation resistance, but has high density, high hardness and poor rebound resilience. And the cold resistance of the NBR structure is deteriorated due to the increase of the content of CAN in the NBR structure. The ethylene propylene diene monomer rubber has excellent ablation resistance and mechanical property, good chemical stability, lowest density, weak polarity, low surface energy, low bonding strength with metal, and poor self-adhesion and mutual adhesion. The silicon rubber has organic and inorganic properties, the Si-O bond energy of the silicon rubber is higher than that of C-C, the silicon rubber is not easy to break and decompose at high temperature, and the low-temperature performance is good. The organic part of the silicon rubber is decomposed into light non-condensation particles at high temperature, and the signal transmittance of the mineral part is high. The silicone rubber has good oxidation resistance and flame retardance, and is strong in micromolecule migration resistance, but the mechanical property of the silicone rubber is poor. To increase the flame retardant and ablation resistance, the amount of inorganic filler is increased, which results in an increased density of the material.
Accordingly, there is a need to ameliorate one or more of the problems with the related art solutions described above.
It is noted that this section is intended to provide a background or context to the disclosure as recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.
