Karakterisasi dan Aplikasi Super-Hydrophobic Coatings Berbasis Lignin pada Papan Serat

Abstract

Fiberboard is widely produced and used as a building material and furniture in various countries. The fiberboard market offers a wide range of high quality fiberboard options in terms of strength, lightweight, and environmental friendliness. This research aims to analyze the characteristics and applications of lignin-based super-hydrophobic coatings on the quality of fiberboard. Lignin is used as a natural additive with the potential to enhance water resistance, while polyurethane serves as the matrix forming the coating. This research conducted physical and mechanical property tests on fiberboard, including density, moisture content, water absorption, thickness swelling, MOE, MOR, and compressive strength, as well as FTIR, XRD, and Py-GC MS analyses. The results showed improvements in mechanical properties and density. Additionally, the characteristics of the coating exhibited hydrophobic properties and structural regularity.
