Study on the Rice Straw-Particleboard by Starch-Based API Adhesive
The rice straw particleboard was prepared using corn starch-based polymer-isocyanate adhesive, and the factors which affected the particleboard properties were investigated .The hot-pressing parameters were fixed as follows: 700kg/m3 of density, 160°Cand15min of hot-pressing temperature and time, 4.2 MPa of unit pressure. The results showed that using the acetic acid which concentration is 1% to spray the surface of straw ,the ratio of straw to wood shavings ：85︰15，the ratio of SBR/PVA：70︰30, glue- spreading 25%, the PMDI addition 3%. Using this adhesive the straw particleboard could meet the requirement of GB/T4897.3-2003.
