| abstract |
The invention relates to the field of rubber materials, and discloses a flame-retardant nitrile-butadiene rubber composition, a flame-retardant nitrile-butadiene rubber/lignin composite material, and a preparation method and application thereof. The composition contains the following components: nitrile rubber matrix, lignin, interfacial modifier, softener, vulcanization aid and flame retardant, wherein the interfacial modifier is epoxidized hydroxyl terminated polybutylene At least one of olefin rubber, epoxy-terminated nitrile rubber and epoxidized carboxyl-terminated nitrile rubber, and the flame retardant is zinc phytate and/or calcium phytate. In the flame-retardant nitrile-butadiene rubber composition provided by the present invention, the prepared nitrile-butadiene rubber/lignin composite material has excellent comprehensive mechanical properties through the synergistic effect of each component. |
