Studi Penggunaan Campuran Fenol Sebagai Antioksidan Pada Karet Alam Sir 20 Dengan Pemvulkanisasi Sulfur Dan Peroksida

Abstract

Blending the research done on phenol as antioxidant SIR 20 natural rubber with sulfur and peroxide vulcanization, the mixing is done by varying the ratio between the antioxidants BHT: Phenol with sulfur and peroxide, as for the comparison of 5:0,1:4, 2:3, 4:1. As for mechanical properties testing conducted is tensile strength test, personal test, Mooney viscosity, ash content test and FTIR tests. from research conducted tensile test results obtained by maximum of 20 with a tensile strength SIR 264.87 KN / m2 vulcanization with sulfur, while the benzoyl peroxide value of the tensile test is the most maximum 5562.27 KN / m2 BHT with a ratio 5:0. whereas the maximum value of Po and PRI vulcanization maximum with benzoyl peroxide is BHT: phenol 1:4 with a value of 56.5%. whereas with sulfur vulcanization with personal values and the most Po maximum without antioxidant that is 92%. Mooney viscosity values, while for most maximum with sulfur vulcanization without the antioxidant value of 112 ML (1+4)’ x 100’ 0 C premises. whereas with benzoyl peroxide vulcanization mooney viscosity values of the most high is SIR 20 with a value of 62 ML (1+4)’ x 100’ 0 C. while ash content with sulfur vulcanization have maximum value is comparison of BHT: Phenol 1:4 is 4.098 %. The value of ash content with benzoyl peroxide that is BHT vulcanization 5:0 with the value 4.006 %. FTIR analysis that there is a change from the chemical interaction of functional groups.
