Abstract
Fireproof panels, and methods for their construction are provided. The fireproof panels comprise at least one sheet including a layer of glass fibres impregnated with at least one fireproof resin free from solvent. The method for the construction includes the successive steps of distributing a fireproof resin in the form of a powder free from solvents on a layer of glass fibres, subjecting the latter to a first compression and heating step to soften the resin and, to a second compression and heating step to cross-link the resin and form the said panel. The panels find particular use in the production of partitions and furnishings.
Claims11
A method for the production of fireproof panels according to RINA standards, said panels including at least one fireproof sheet which consists of glass fibers and a fireproof phenol-formaldehyde resin, the method comprising the successive steps of:
- forming a layer of the glass fibers:
- distributing the fireproof phenol-formaldehyde resin uniformly, in the form of a powder free from solvents, on the layer of glass fibers, in quantities of at least 5 g but no higher than 6 g of the resin per 100 g of the glass fibers;
- simultaneously compressing and heating the layer and the distributed resin to a temperature at which the resin softens for sufficient time to cause the softening of the resin, thereby impregnating the layer of glass fibers with the resin to form an impregnated layer;
- and
- compressing the impregnated layer at the cross-linking temperature of the resin to obtain said fireproof sheet.
