Description

technical field

[0001] The invention relates to the field of modified rubber, in particular to a high-performance conductive rubber material for aerospace and its preparation method and application. Background technique

[0002] At present, the conductive and thermally conductive rubber materials on the market are mainly conductive and thermally conductive rubber based on silicone rubber, and the volume resistivity is generally 10. 5 ~10 9 About Ω·cm, after adding some metal conductive powder fillers, it can reach several thousand or hundreds of ohm cm, and the thermal conductivity is usually 1.2~3W / (m.K). Some conductive and thermally conductive materials based on nitrile rubber or butadiene rubber are better than silica gel in terms of mechanical properties and chemical resistance, but due to the characteristics of the material itself, these conductive materials cannot be applied to aviation with harsh conditions. aerospace field. Now, with the development of my country...
