RECYCLED VINYL WALLPAPER- A NEW COMPOSITE

摘要

Mechanical recycling of waste polymeric based composites allows production of same or similar products, but in the case of vinyl wallpaper the quality of recovered material combines the cellulose component with the vinyl PVC resulting in a new composite which can have completely different applications compared with the original vinyl wallpaper. Vinyl wallpaper is generally composed of Polyvinyl chloride combined with cellulose fibre and with certain formulations a small percentage of different polymer based additives. It has been demonstrated and described in a previous presentation that this post industrial waste material can be recycled, the present paper will demonstrate that this recyclate can be claimed to be a new vinyl based composite. The present paper will also demonstrate advantages of using modified extrusion technology to recycle wallpaper continuously without degradation of base components. With properties characterisation and evaluation it will be demonstrated that this material can have different applications compared with vinyl wallpaper.
