Pengaruh anti oksidan phenyl beta naphtylamine (PBN), dan variasi rss dengan SBR terhadap sifat fisika kompon talang karet

The aim of the research was to find some important characteristics of rubber gutter compound such as tensile strength, elongation at break, and constant deflection because of adding Phenyl Beta Naphtylamine on it. Rubber gutter compound was made from mixing of natural (RSS) and synthetic rubber (SBR) and some aditives such Zink Oxide, Stearic Acid, Napthenic Oil, HAF black, Phenyl Beta Naphtylamine, Mercapto Benz Thiazol Disulfide, Diphenyl Guanidine and Sulphur. Three compositions of RSS/SBR and Phenyl Beta Naphtylamine were used in the research, namely 40/60; 50/50; 60/40, and 1 : 1,5 ; 2 respectively. A statistical procedure was used to analyze the data of the physical characteristic of rubber gutter compound produced. The results were compared to the data of the physical characteristic of rubber gutter compound produced. The results were compared to the physical strength of rubber gutter available in the market. From the statistical analyses they denoted that the levels of Phenyl Beta Naphtylamine gave significant effects on elongation at break and constant deflection however there was no effect on tensile strength. The composition levels of RSS /SBR could produce compounds which were significant difference in the tensile strength, elongation at break and constant deflection. Compounds resulted from this research had better tensile strength and elongation compared to rubber gutter available in the market.
