An Investigation of Fabrication Thermal Insulation Wood-Based Composite Using Nanotechnology

摘要

In the present study, the potential use of nanotechnology was examined to improve thermal insulation properties of medium density fiberboard (MDF). For this, Na~+ montmorillonite (NaMMT) nanoclay was added to urea formaldehyde resin at three levels of 0%, 2.5% and 5% based on the oven dry weight of resin for produce the MDF. The boards were produced with two densities of 0.65 and 0.75 g/cm . In order to characterize the structure of the MDF, scanning electron microscopy (SEM) was applied, and the thermal insulation properties were examined using thermal conductivity test. Characterization of the MDFs shows that dispersed and exfoliated structures were generated by the hot press. The results of thermal conductivity test indicated a desirable effect of nanoclay on thermal properties of MDF. The nanoclay reduced thermal conductivity by 10-45%.
