Use of antiBr printed circuit boards（PCBs） made epoxy resin is more and more popular and can generate large amount of solid wasteTheir thermostability and characteristics of pyrolysis reaction including kinetics was investigated in atmosphere of argon using thermogravimetric(TG)analysis at various hearting rates(5

10

20

30℃·min-1).The kinetic parameters of pyrolysis reaction including activation energy E were determined by Kissinger’s differentiation and FlynnWallOzawa’s integration methodsA study by CoatsRedfern method indicated that the Valensi equation was a good approximation of the thermal decomposition reaction kinetics

the order of decomposition reaction was 2

the average activation energy E160.62 kJ·mol-1

and the thermal decomposition mechanism function α+(1-α)×ln(1-α).
