Application of gas grafting with palmitoyl chloride to manufacture hydrophobic decorative wood veneer

초록

In this study, the feasibility of hydrophobizing pine wood veneers through gas grafting with palmitoyl chloride using a hot press was explored. To achieve this, the hydrophobization characteristics of wood veneer were analyzed under various conditions, including pressing temperature, time, and concentration of palmitoyl chloride. The results showed that the gas grafting treatment successfully hydrophobized the pine wood veneer, and that the pressing temperature and concentration of palmitoyl chloride were the main factors influencing the grafting. The hydrophobization efficiency increased with an increase in the pressing temperature and palmitoyl chloride concentration, whereas the pressing time had little effect. However, under conditions of excessively high palmitoyl chloride concentration, pressing temperature, and excessively long pressing time, relatively large color changes and a pH drop in the veneer were observed. Therefore, it was concluded that to treat pine wood veneer with a diluted solution of 0.5 % palmitoyl chloride at 180 degrees C for 6 s was appropriate.
