|Summary / Kata Kunci||:||ABSTRACT
Reclaiming rubber was one of alternative effort to depress the environmental problem caused of used tyre. Reclaiming was a procedure in which vulcanized waste was converted, using mechanical and thermal energy, into a state in which it could be mixed, processed and vulcanized again. Several reclaiming procedures were known, the common feature of which was the effect of elevated temperature. Microwave could be used for heat treatment of rubber waste.
The aim of the research were to study the effect of microwave heating in preparation reclaimed rubber from used tyre and to study the effect of reclaimed rubber usage on vulcanization character of compound and physical properties of vulcanizate produced.
Completely Randomized Design in factorial pattern was used in this study. The first factor was power output of microwave heating for heat treatment of used tyre rubber i.e. without heating (DO); microwave heating with power output of 100 watt and 200 watt. The second factor was ratio Ribbed Smoke Sheet 1 (RSS 1) to reclaimed rubber i.e. 80 : 20 (B20); 60 : 40 (B40); and 40 : 60 (B60).
The results showed that all treatments had not significantly different on vulcanization character covered time scorch (ts2), optimum cure time (tc90), and vulcanization rate, except torque modulus (Dt). Reclaimed rubber prepared without heating and 40 part of it in vulcanizate showed the highest torque modulus (29.24 kgf cm). Reclaimed rubber prepared with microwave heating for 100 watt and 40 part of it showed relatively better physical properties than other treatments on modulus 100% (2.24 MPa), tensile strength (5.67 MPa), tear resistance (24.34 N/mm), and permanent set (3.80%).
