摘要

Natural products used as plasticizer can inhibit its migration in rubber and improve the dispersion of inorganic power. Herein, styrene butadiene rubber (SBR) was plasticized by poly-cardanol (PCA) originated from the Friedel-Crafts alkylation without solvent of cardanol which was extracted from abandoned cashew nut shell. Results show that the Mooney viscosity of SBR/PCA compounds decreases from 45.8 to 34.7 and T-g from -52 degrees C to -56.3 degrees C when PCA is added from 0 to 30 phr. Moreover, the elongation at break of SBR contained 30 phr PCA increases by 515% compared with SBR. PCA also shows amphiphilic, which is verified by the improved dispersion of SiO2 in SBR/PCA compounds. The swelling ratio of SBR/PCA/SiO2 vulcanized rubber decreases and the crosslinking density increases. Meanwhile, the elongation at break of SBR70-40 vulcanized rubber is 17.3%, which is higher than that of SBR100-40 vulcanized rubber. PCA, acted as plasticizer and compatibilizer, provides a simple and green way for the application of natural products in the rubber industry.
