Abstract: | The effects of manufacturing parameters on mechanical properties of medium density fibreboard (MDF) bonded with modified soy
protein-based glue were studied to find an appropriate manufacture technology. Physical properties of MDF made with different
amount of wax emulsion were measured. Results indicated that water repellent had no obvious influence on physical properties
of soy protein-based MDF boards. The fiberboards bonded with soy protein-based glue showed stronger water resistance properties
than those bonded with urea–formaldehyde (UF) resins. Furthermore, the soy protein-based MDF boards had good quality 25.2%
24 h soak thickness swell (TS), 29.9 MPa modulus of rupture (MOR), 3130 MPa modulus of elasticity (MOE)], which met requirements
of Chinese national standard. Practical processing parameters were obtained by orthogonal experiment, i.e., glue content 8.0%,
hot-press temperature 200 °C, and hot-press time 150 s. |
