Effect of recycled ceramic waste particles on kinetic of curing and thermal degradation of unsaturated polyester resin

Abstract

In this study, the effect of recycled ceramic waste particles on the curing reaction and thermal degradation of unsaturated polyester resin has been studied kinetically. Methyl ethyl ketone peroxide and cobalt octoate were used as initiator and promotor, respectively. The porcelain powder obtained from ceramic waste was used as filler. The effect of methyl ethyl ketone peroxide and porcelain powder were investigated by measuring the gel time and exotherm behavior. Also, thermal properties have been carried out using TGA at different heating rates in an argon atmosphere, and the results were analyzed by the Friedman method. The results indicate that the curing process is affected by the incorporation of ceramic particles in two ways. Therefore, the use of ceramic particles increases the induction time and decreases the exotherm properties of unsaturated polyester resin. In addition, the results obtained by Friedman method demonstrates that the incorporation of ceramic particles in the resin increases the activation energy, and consequently improves the thermal stability of unsaturated polyester resin.
