Abstract

OSB (Oriented Strand Board) have a great prominence in the sector of engineered wooden panels, especially with application in construction industry, due to their mechanical properties. However, to ensure ideal and competitive properties with other building materials, better performance of their physical properties such as moisture content and thick swelling should occur, aiming at greater durability. One alternative to improve such properties is the addition of nanomaterials to the boards, as they have dimensions at nanometric levels and have favorable characteristics in relation to them in macroscale. The purpose of this work is to evaluate the influence on the physical-mechanical performance and heat transfer inside the panels from the addition of zinc oxide (ZnO) nanoparticles in two different percentages (0.25% e 0.50% in relation to the adhesive mass) in OSB panels produced with Pinus wood and two different adhesive (phenol-formaldehyde and castor oil). The study aims to evaluate the influence of nanomaterial on the physical-mechanical performance of the panels, using as a reference for the analysis of the results boards produced without the addition of nanoparticles and commercial values and related literature. The characterization will be carried out according to the specifications of the normative documents and the statistical analysis of the data to verify the normality and significant differences between treatments.
