Effect of the Flux on the Fire

In this paper, two kinds of glass frit and zinc borate as fluxes were used to prepare ceramifiable EPDM rubber composites, and the mechanical test, SEM, XRD and TG-DSC were used to study the effects of fluxes on the thermal stability and pyrolysis performance of composite materials. The results showed that the addition of the three kind of fluxes helped the filler to form a large amount of liquid phase structure at high temperature, and then a good ceramic structure formed to improve the thermal stability of the composite material and the bending strength of the pyrolysis product. The XRD analysis showed that the main phases after pyrolysis of composite materials adding glass frit A were forsterite and quartz, and the main phases after pyrolysis of composite materials adding glass frit B or zinc borate were spinel and quartz
