ABSTRACT:
Fiber boards of high strength which are highly water- and flame-resistant are disclosed, as well as a method for making such boards and an inorganic binder composition for bonding wood fibers. The boards comprise a lignin-containing fiber material, a binder derived from a binder composition comprising an alkali silicate solution, sulphur and/or an inorganic sulphur compound, and a calcium and/or magnesium compound and, optionally, fillers and/or hydrophobing agents.
The fiber boards are manufactured by mixing the lignin-containing fiber material with the binder composition and optional further additives, whereupon the mix is compressed at a high pressure and at a temperature of 130.degree.-230.degree. C.
