METHOD FOR RECYCLING INSULATING WOOL, APPARATUS FOR PROCESSING INSULATING WOOL, FIBRE-REINFORCED FOAM, WOOD-BASED MATERIAL WITH COMBUSTION RESISTABILITY AND METHOD FOR PRODUCING A WOOD-BASED MATERIAL WITH COMBUSTION RESISTABILITY

摘要

The present invention relates to a method for producing a recycled insulating material from insulating wool, said method comprising the steps of: comminuting insulating wool to give a first intermediate comprising fibre balls; adding binder to the first intermediate to give a second intermediate; hot-pressing the second intermediate into the desired shape, to give a third intermediate; and curing the third intermediate to give the recycled insulating material. The present invention further relates to a method for recycling insulating wool, an apparatus for processing insulating wool, and a fibre-reinforced foam. The invention additionally embraces a fire-resistant wood-based material and a method for producing it.
