Abstract
A process for producing a flaked cellulose-based thermal- and/or acoustic-insulating material includes preparing a cellulose-based pulp and providing a web of paper having a given thickness, starting from the pulp. A coating having a mixture containing a first substance having a flame-retardant function and a second substance having an anti-mould function is applied on the web. The coated web is subjected to a milling operation so as to provide flakes of flaked insulating material.
Claims9
A process for producing a flaked cellulose-based thermal- and/or acoustic-insulating material, comprising:
- preparing a cellulose-based pulp;
- providing a web of paper having a given grammage and a given thickness, starting from said pulp;
- applying on said web a coating comprising a mixture containing a first substance having a flame-retardant function and a second substance having an anti-mould function;
- and
- subjecting said coated web to a milling operation so as to provide flakes of said flaked insulating material.
A process for producing flaked insulating material using a paper-production line, comprising,
- supplying a mixture containing a first substance having a flame-retardant function and a second substance having an anti-mould function to a size-press or film-press station;
- and
- producing, via said line, a web of paper having a given grammage and thickness, and via said size-press or film-press station applying on said web a coating constituted by said mixture.
