Study on the Surface Properties of Hot-Waxed Wood with MCC Filled Fischer-Tropsch Synthetic Wax

This study aims to enhance the mechanical properties of hot-waxed wood by incorporating microcrystalline cellulose (MCC), thereby addressing the issue of inadequate surface durability. We investigated the effects of varying mass fractions (0%, 5%, 10%, 15%) of MCC on multiple surface properties of hot-waxed wood modified with natural wax and maleic anhydride-ethyl acetate copolymer-grafted Fischer-Tropsch wax. These properties encompass adhesion, hardness, abrasion resistance, impact resistance, surface roughness, gloss, and hydrophobicity. To gain deeper insights into the reinforcing role of MCC, analytical techniques such as Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), and Scanning Electron Microscopy (SEM) were employed to comprehensively characterize the chemical structure, crystalline structure, and surface morphology of the samples. The results reveal that, upon the addition of 5% MCC, the hot-waxed wood treated with modified Fischer-Tropsch wax demonstrates a 41% increase in surface adhesive strength, an improvement in hardness from 2H to 3H, a reduction in surface impact resistance from grade 5 to grade 2, and a 72% decrease in wear mass. Additionally, it exhibits enhanced surface hydrophobicity and thermal stability, while preserving its decorative appearance. These findings endorse the use of MCC in hot-waxed wood, offering significant potential in fields like wooden architecture, indoor wooden decorative panels, and furniture.
