| Summary: | The objective of this study was to evaluate the properties of particleboard prepared from starch-based adhesive,
modified with sodium trimetaphosphate as a binder. Three-layer experimental panels were manufactured from a homogenous
mixture of Acacia mangium and rubberwood. Panels were prepared from two different target densities of 0.60 g/cm3
and 0.80
g/cm3
and four different combinations of adhesive. The four combinations of adhesives were sequentially urea-formaldehyde
(UF), native oil palm trunk starch (OPT-starch), sodium trimetaphosphate (STMP), modified starch, and STMP-starch mixed
with 2% UF. Adhesive properties were analyzed by thermogravimetric (TGA), differential calorimetry (DSC), X-ray
diffractometer (XRD), and scanning electron microscopy (SEM). The prepared panels were evaluated for their physical and
mechanical properties. An experimental panel with 0.80 g/cm3
density showed better mechanical and physical properties
compared to 0.60 g/cm3
. Oil palm trunk starch modified with sodium trimetaphosphate exhibited an improvement in physical
and mechanical properties when it was used in combination with UF resin. |
