Patent DE-4312564-A1 (DE)
Inventor: HOFMANN MICHAEL
IPC: C08L97/02
Filed: 1993-04-17
Abstract: The method proposed calls for the manufacture of fibreboard made of lump-form wood particles plus less than 10 % by wt. of polyurethane adhesive as binder. The wood particles are heated in steam at an overpressure and thus broken up to form fibres. The fibres are used at a concentration giving an overall bulk density of about 550 to 650 kg/m<3> and the binder at a concentration of about 0.5 to 4.0 % by wt., in particular 1.0 to 3.0 % by wt., relative to the dry wood. The water vapour formed on heating is also passed, without preliminary condensation, through the drier and hence used to form a coating of polycarbamide which prevents premature reaction of the binder.
