ABSTRACT

It has been proved that the more than 80% leukemia were caused by indoor formaldehyde pollution. To improve the self-bonding reactivity and prepare self-bonded board with formaldehyde-free, Eucalyptus wood?fibers were pretreated, processed and analyzed by 13C-NMR and FT-IR. The results showed that the IB of SBBs reached the maximum of 1.53MPa with the pretreatment time of 3h. FT-IR and 13C-NMR spectra showed that the group and reactivity of wood?fibers?had different?changes by acidic?oxidation pretreatment. It suggested that cellulose,?hemicellulose and lignin produced the bonding?reaction, helped the pretreated fiber to be self-bonded, improved the water resistance and the high IB.
