EFFECT OF THE PERCENTAGE OF RUBBER COMPOSED BY NATURAL RUBBER, RUBBERIZED FILLED WITH SOOT ON THEIR TENSILE PROPERTIES AND BAKING BEHAVIOR
Resumo
The purpose of the present studies is to provide a perspective of the main factor of the soot reinforcement effect as filler in composite with the base of natural rubber, rubberized or limited tires. For this purpose, natural rubber composites (NR-CB) were extracted by Soxhlet and thermal extraction, finally, Soxhlet extraction with the longest operating time removed more untreated rubber than thermal extraction and performed more efficiently and optimally.
Using Tg curves to extract Soxhlet for 120 hours and thermal extraction for 24 hours for NR-CB N550 composite, the results obtained from the extraction step were evaluated.
To further investigate the difference of soot type in the reinforcement of the composite, the aforementioned methods were performed with two natural rubber composites with two types of soot N550 and N660 after determining the carbon content of the gel, the results were compared with the results obtained from the measurement of soot surface structure and the physical and rheological properties of the composite.
