Abstract
This basic research was conducted to support the development of woodcraft bio-adhesives using peach gum, which is the resin produced by peach trees. The synthesis conditions of these adhesives were optimized by performing 144 experiments. The application potential of peach gum adhesives was explored by comparing their properties with those of three natural adhesives and four synthetic adhesives. The best adhesive strength was obtained by dissolving the resin in 80 mL of distilled water containing 1.5 g NaOH, 1.65 g H2O2 ( pH 8.0-9.0), 0.5 g NaClO, and 0.5 g H2BO2. The adhesive strength, which showed minimal changes and excellent reversibility, was 125.39 kgf/cm2. Ultraviolet radiation-mediated deterioration in strength in the absence of total aerobic bacteria was negligible (△E*ab = 2.75). These data confirm the potential value of peach gum-based bio-adhesives for woodcraft as well as their utility as alternatives for natural and synthetic adhesives used for the manufacture and restoration of handicrafts and preservation of cultural assets.
