Particulate composite based on coconut fiber and castor oil polyurethane adhesive: An eco-efficient product
چکیده انگلیسی

This paper presents a study on the potential use of coconut fiber as material to produce particleboards, with two different densities (0.8 g/cm3 and 1.0 g/cm3), using castor oil-based polyurethane adhesive and urea-formaldehyde. The quality of the product that can be produced by industry was evaluated according to the normative NBR 14.810:2006, where density, thickness swell (TS), absorption, modulus of elasticity (MOE), modulus of rupture (MOR) in static bending and internal bond (IB) were determined. From the results, there was a decrease in TS and increase in MOR of coconut fiber panels with polyurethane resin panels compared with coconut fiber and resin urea-formaldehyde. Scanning microscopy electronic images (SEM) indicated that castor oil-based polyurethane adhesive occupies the gaps between the particles, a factor that contributes to improved physical and mechanical properties of the panels. The assessment of durability through accelerated aging tests shows that panels protected with waterproofing material can be used in environments that have contact with moisture.


► Particleboards of coconut fiber.
► Particleboards with agro industrial wastes and castor oil-based adhesive.
► Durability of particleboards.
