Abstract
Excellent wood plastic composite produced by reaction of rice husk, recycled high-density polyethylene (RH/HDPE) and polyethylene grafted maleic anhydride (PEGMA). The impact of varying concentrations of polyethylene grafted maleic anhydride (PEGMA) as a coupling agent in rice husk and recycled high-density polyethylene composites (RH/HDPE) on their mechanical and physical properties was examined. Analysis using scanning electron microscopy (SEM) revealed improved homogeneity of RH fibers within the HDPE matrix due to the presence of PEGMA. FT-IR findings indicated the formation of a new chemical bond at 1734 cm-1 between RH fibers and HDPE chains. Thermal gravimetric analysis (TGA) demonstrated enhanced thermal stability with higher PEGMA concentrations. The results revealed that the modulus of elasticity, maximum stress, maximum strain, and Shore D hardness of the samples increased with increasing PEGMA concentration, reaching a peak and then decreasing after reaching 2% wt. Abrasion resistance improved with higher PEGMA concentrations. Furthermore, swelling parameters in distilled water exhibited significant enhancement with increasing PEGMA concentration. The study will help in efficient utilizing rice husk and recycled HDPE as an alternate resource for the industrial manufacture of particleboards.
