Abstract

Beeswax was modified through the direct blending of nano-TiO2, chitosan, acid dyes, and neutral dyes. With the varied modified beeswax, hot waxing was conducted on compressed poplar wood. Treated wood surfaces were characterized with scanning electron microscopy and thermogravimetric analysis. Results show that the C, O, N, Au, S, and Ti elements in modified beeswax successfully penetrated into pits of compressed poplar wood, imparting rich colors to the wood surface. The blending of 10% (mass fraction) beeswax, 0.2% chitosan, and 0.05% neutral red was the best treatment for mulation for improving the in-surface staining uniformity, durability, surface gloss, contact angle, and texture conspicuity of compressed poplar.

Highlights

  • Beeswax is a widely used protective material in traditional Chinese wooden architecture and hardwood furniture

  • 0.2% chitosan into 10% beeswax can produce the greatest improvement for the surface performance of compressed poplar wood after hot waxing

  • The B3 = beeswax + neutral red + chitosan, range was widened through the addition of chitosan to

Summary

Introduction

Beeswax is a widely used protective material in traditional Chinese wooden architecture and hardwood furniture. During the hot waxing of hardwoods, problems such as discoloration, poor durability, and high cost often occur. China is a country lacking valuable timber resources but is rich in fast-growing wood resources. How does one effectively use fast-growing wood resources, reduce costs, and improve the surface properties of wood? One possible solution is to treat the wood surface with hot modified beeswax. Scholars have studied the engineering process of wax modification and traditional waxing, and factors affecting the quality of waxing [1,2,3]. Krause et al studied the preparation process of lignite wax and improved antibacterial and anticorrosion properties of the wax on wood surfaces [4]
