Construction of renewable biomass cardanol functionalized spherical nanoparticles achieving favorable interfacial interaction and thermostability in styrene butadiene rubber matrix

Abstract

AbstractTo expand the application of natural resources in the green rubber industry and reduce the dependence of rubber additives on the non‐renewable petrochemical resources, a novel cardanol‐based natural rubber additive (silica‐s‐LPCGE) is prepared. Compared with the directly adding of silica and LPCGE, silica‐s‐LPCGE is assisted to form an effective interfacial interaction between the rubber matrix and the filler during rubber vulcanization by the immobilized LPCGE on silica surface, to improve the mechanical property and processability of styrene‐butadiene rubber (SBR)/silica‐s‐LPCGE composites. Meanwhile, with the introduce of silica‐s‐LPCGE, the aging resistance and migration resistance of the SBR composites are also improved obviously. The preparation of this novel multifunctional supported natural biomass processing additive provides a new possibility for the preparation of green rubber additives.
