Improvement of the Dimensional Stability of Rubber Wood Based on the Synergies of Sucrose and Tung Oil Impregnation

Rubber wood often exhibits dimensional instability during use, which seriously hinders its widespread application. In order to enhance the stability of rubber wood, a two-step method was employed in this study modify using two plant-derived compounds, namely sucrose and tung oil. Samples treated alone with or oil were also prepared. The water absorption, stability, thermal modified untreated evaluated. results show that samples 30% had excellent resistance based on synergistic effect After 384 h immersion, group presented reduction absorption by 76.7% compared control group, anti-swelling efficiency 57.85%, 66.81% higher than treatment alone. Additionally, leaching rate decreased 81.27% sample solution Simultaneously, showed better stability. Therefore, demonstrates is an eco-friendly, economical, highly efficient approach potential expand range applications products.
