Title:
CELLULOSE MATERIAL WITH ENHANCED FIRE RESISTANCE
Document Type and Number:
WIPO Patent Application WO2004033787
Kind Code:
A3
Abstract:
The invention concerns a cellulose material having enhanced fire resistance, comprising, covalently bound to its cellulose structure, a polymer having the following structural unit: (A), partly substituted by dehydroxyphosphoryl groups, said covalent bond being in particular obtained by reacting urea. The method for preparing said cellulose material with enhanced fire resistance consists in: a) preparing a water-soluble polymer having the structural unit (A), partly substituted by dehydroxyphosphoryl groups, b) optionally mixing said polymer with urea, c) contacting said polymer or said mixture with the cellulose material, d) bringing the whole resulting product to a temperature ranging between 140 and 180 DEG C.
