Abstract:
Results from the differential scanning calorimetry (DSC) analysis indicated that the reaction of NLFS-1 scavenge with formaldehyde could be measured, most of free formaldehyde in UF resin could react with the scavenge, and reacting amount would depend on molar ratio or free formaldehyde of the resin. The scavenge of 5% is high capable of catching formaldehyde in particleboard and medium density fiberboard panels with low molar ratio and without dehydration UF resins, and the formaldehyde emission value can meet European standard E1 or Chinese Standard GB-T11718-1999 Grade A. The IB values could be improved well after post isothermal treatment, but the formaldehyde emission would increase a little.
Key words: Low formaldehyde emission particleboard, Scavenger, Urea formaldehyde resin without dehydration
