METHOD OF MODIFICATING SURFACE OF POLYOLEFIN COMPOSITION USING WASTEPOLYURETHANE BY USING RAY AND POLYOLEFIN COMPOSITION THEREOF

摘要

The present invention relates to a method for modifying a polyolefin-based polymer by utilizing waste polyurethane by using radiation and a polyolefin-based polymer modified through the same. Waste polyurethane is made into fine powder, and surface modification is performed through a radiation technique, and compatibility with a conventional polymer is improved. An environmentally-friendly waste polyurethane recycling technique according to the present invention may minimize environmental pollution caused by landfill and calcining of waste polyurethane. Moreover, waste polyurethane is utilized as a filler of a polyolefin-based polymer, so physical properties of a conventional polyolefin-based polymer may be improved. Furthermore, a used amount of an environmental pollution material is minimized by replacing a conventional chemical treating technique, thermal/mechanical properties of a conventional polymer material is improved to be applied and utilized in various fields.
