Abstract

In order to solve the recycling problem of waste
fibers, waste fiber/polyurethane flame retardant insulation board was prepared
by blending- hot pressing method with waste cotton fiber, discarded
polyurethane, AC (azodimethylamide) foaming agent and APP (ammonium
polyphosphate) flame retardant as raw materials. The necessary conditions to
the optimized technology was mass fraction of waste fibers 10%, mass fraction
of AC foaming agent 3%, mass fraction of APP flame retardant 15%, hot pressing
pressure 7MPa, hot pressing temperature 180℃, length of waste fibers 20mm,
mixing temperature 175-180℃, hot pressing time 8min, cool-down time 2h, which
were optimized by thermal conductivity coefficient, limit oxygen index and
mechanical properties.The flame retardant mechanism and effect of the waste
fiber/polyurethane flame retardant insulation board was analyzed by TGA
(Thermogravimetric Analysis) and residual carbon ratio. Finally, the abaqus finite
element simulation software was used to simulate the thermal conduction process
and verify the correctness of model.
