Abstract (en)
A process for manufacturing a flocks-based, cellulose-based thermal and/or acoustic insulating materials is described. The process is characterized by the fact it comprises the following steps: - preparing a cellulose-based pulp; - adding to said pulp a mixture (A) comprising at least one substance having a fireproof property and/or at least one substance having an anti-mould property; - making a paper web having a determined thickness and grammage, from said pulp; - applying on both sides of the web the mixture (B) by means of "applicators" inserted during the re-wetting and drying steps; - subjecting said web to a grinding operation in order to obtain flocks forming said flocks-based insulating material.
