METHOD OF RECYCLING CROSSLINKED WASTE FOAMS OF LOW-DENSITY POLYETHYLENE

摘要

PURPOSE: A method of recycling a waste foam agent based on low-density polyethylene is provided is provided to remarkably reduce the amount of buried or burned waste low-density polyethylene. CONSTITUTION: A method of recycling a waste foam agent based on low-density polyethylene comprises the following steps: de-crosslinking the waste foam agent at 350~500 deg C with a reaction condition of the pressure of 5~30 mega pascals for 2~30 minutes using supercritical ethanol; and converting the waste foam agent based on the low-density polyethylene into a recycling low density polyethylene class resin. The waste foam agent based on the low-density polyethylene is the waste foam agent using either an organic peroxide cross-linking method or an electron beam cross-linking method.
