Effects of UV for cycloaliphatic epoxy resin via thermokinetic models, novel calorimetric technology, and gaseous product analysis

摘要

The cycloaliphatic epoxy resin which we selected was 3,4-epoxycyclohexane methyl-3'4'-epoxycyclohexyl-carboxylate (EEC). Epoxy resin has numerous applications, such as in varnishes, tires, and electronic materials. However, the extensive uses of chlorofluorocarbon (CFC) compounds in the last century resulted in the formation of a hole in the ozone layer. As a consequence, solar radiation is intensifying gradually, so we should avoid continuous irradiation by sunlight. The results of solar radiation could exacerbate its deterioration and photolysis. Through thermogravimetry, and gas chromatography/mass spectrometry, we analyzed the onset temperature and gaseous products of EEC. Thermokinetic data were used to determine the thermal stability parameters through simulation using a best-fit approach via applying high-level simulation software to assess the degree of decomposition heat. The goal of this study was to establish the thermal hazard parameters and gaseous product analysis for the effects of UV for EEC in turn, as well as the probability of severity of thermal catastrophe.
