COMPOSITION FOR MANUFACTURE OF PAPER-BASED FILM MATERIALS Russian patent published in 2001 - IPC

FIELD: production of papers used in furniture manufacture and standard house building. SUBSTANCE: composition contains amino formaldehyde resin such as carbamidomelamine formaldehyde resin, stabilizer and activator. Carbamidomelamine formaldehyde resin is produced at initial melamine- formaldehyde ratio of 1:3-6, with following condensation of prepolymer with carbamide until final amino component and formaldehyde ratio is 1:1.44-0.8. Such composition allows high-quality, low-toxic facing materials with improved hydrolytic stability and elasticity to be produced. EFFECT: improved quality of paper and wider range of usages. 2 cl, 1 tbl, 12 ex
