Description

technical field

[0001] The invention relates to the field of modified rubber, in particular to a rubber material with high electrical conductivity, thermal conductivity, oil resistance and aging resistance, and a preparation method and application thereof. 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 thousands or hundreds of ohm cm, and the thermal conductivity is usually 1.2 ~ 3W / (m.K). However, these materials can only have one characteristic, and due to the characteristics of the silica gel itself, the mechanical properties are greatly reduced after the addition of conductive and thermally conductive fillers (tensile strength is about 1 to 4 MPa, and elongation at break is about 100 to 300%), and Its...
