The main chemical components of tea tree essential oil (TTO) are monoterpene compounds, including terpine-4-ol,1,8-cineole, para-cymene and γ-terpene. Among them, terpine-4-ol 1,8-cineole the antibacterial components. microcapsules were prepared by orthogonal experiments with core-wall ratio, emulsifier concentration, mass ratio Tween-80 to SDBS oil-water as variables. Through analysis yield coverage rate nine kinds microcapsules, concentration was determined most influential factor for TTO-chitosan six a single-factor experiment. With increase in Escherichia coli increased first then decreased, Staphylococcus aureus first, decreased increased, effect better than that coli. When 4% (13# microcapsule), overall performance coating better, microcapsule dispersion uniform, showing round spheroid shape, particle size mostly distributed between 4 8 μm. against 72.95%, 75.81%. color difference 2.77, glossiness at 60° incidence angle 22.8 GU, visible light transmittance 87.80%. roughness 0.304 μm, elongation 17.47%. research results provide technical reference application an water-based on wood surface.
