Abstract EN
Micro- and nanofibrillated cellulose (MNFC) was extracted from pineapple stems by acid hydrolysis, then characterized and tested in two concentrations (0.5 and 1.0 wt%) in polyvinyl acetate (PVAc) and urea-formaldehyde (UF) adhesives.
The modified adhesives were used to glue three tropical wood species (Vochysia ferruginea, Cordia alliodora, and Gmelina arborea), and their corresponding bond strength resistance was determined.
MNFC and the correspondent adhesives were characterized by TGA, FTIR, SEM, TEM, AFM, and viscosity determination.
The TGA analysis of MNFC showed three decomposition reactions.
The SEM, TEM, and AFM evaluations demonstrated the presence of micro- and nanosized dimensions of particles after the acid hydrolysis of pineapple stems.
Adding 1 wt% MNFC to PVAc and UF adhesives increased their thermal stability in similar manner.
Viscosity diminished in both modified adhesives with MNFC; however, this reduction did not affect the adhesion properties in the tropical wood tested.
MNFC added to PVAc and UF adhesives improved shear strength (SS) of the glue line in the three tropical species tested.
The highest SS increase was obtained when adding 0.5 wt% MNFC to PVAc in V.
ferruginea, and 1 wt% MNFC concentration in the case of C.
alliodora and G.
arborea.
In the case of UF adhesives, the application of 1 wt% MNFC produced significant differences in SS for the three tropical species studied.
