Novel UV/EB Curable Flame Retardant Coatings Using Unique Water Compatible Oligomers; Applications of the Coatings Particularly for Recycling Waste Products Such as Banana Tree Trunks.

摘要

The use of novel water compatible epoxy acrylate oligomers in UV curing of unique coatings onto cellulosic materials particularly of waste origin is described. The application of the process in treating a novel veneer/paper product obtained from the peeling of waste banana tree trunks is discussed. This product which is not pulped is shown to possess exceptional flame retardancy properties, the potential of which is discussed in the fields of packaging, timber veneers and general paper applications. Mechanically pulped paper from the waste banana tree has also been prepared, coated and UV cured and its flame retardancy compared with the peeled product, and also commercial chemically pulped papers. The mechanism of the flame retardancy is examined, especially the environmental advantages of not using halogens for this purpose. The commercial potential of the flame retardant product from the peeling process is discussed and is supported by a carbon trading/ecological footprint analysis.
