Abstract:

Pyrolysis of printed circuit boards （PCB）made with anti-Br type epoxy resin were investigated in nitrogen.The effect of temperature(300—900℃), heating rate(10—40℃·min^-1)and holding time（30—60 min）on the yield of pyrolysis products was studied.Pyrolysis oil and residue were analyzed by infrared spectra, gas chromatography-mass spectroscopy（GC/MS）, elementary analysis and scanning electron microscope.Results show that solid residues account for about 61.74%—71.08%
