Abstract

In the present study, the properties of medium-density fiberboard made with urea formaldehyde resin as a control sample and compared with MDF made using chitosan and carboxylic acids were investigated. Various compounds including chitosan acetate solution, chitosan acetate – butane tetra carboxylic acid solution, chitosan acetate-citric acid solution and citric acid solution were investigated. The chemical structure of specimens was investigated by Fourier transformed infrared spectroscopy (FTIR). The results of spectroscopy clearly showed the difference in the use of different compounds. The formation of cross-links between cellulose chains and carboxylic acids was confirmed, as well as the formation of hydrogen bonds between chitosan and lignin. Specimens made with the combination of acetate chitosan-BTCA showed better dimensional stability and the internal bonding of MDF specimens made with chitosan acetate solution was higher than controls. chitosan acetate-BTCA compound can be considered as a successful substitute for urea-formaldehyde adhesive due better dimensional stability and good internal bonding of the fiberboards.
