摘要： Recent advances address the development of anti-mildew and UV-resistance microcapsules for wood. IPBC (3-iodo-2-propynylbutylcarbamate) is enclosed in the drug-loaded carriers through slow release, resulting in the anti-mildew process. Anti-mildew experiments showed that the control effectiveness of 1.25wt% nano SiO2-IPBC microcapsules was 78.125% against Botryodiplodia theobromae. In addition, a novel angle of view is discussed, which is the UV-resistance, including different mass fractions of nano SiO2-IPBC microcapsules, IPBC and the control group. Different FTIR characterizations and surface colors related to impregnated wood samples are discussed. Nano SiO2-IPBC microcapsules had better bonding performance and UV-resistance than IPBC due to the synergistic effect of nano SiO2 and IPBC in the microcapsules. Color measurements showed that the UV-resistance of microcapsules was better than 1.25wt% IPBC-impregnated wood samples. It helps us open new horizons to anti-mould agent, which offers multi-function of great anti-mildew effect and excellent UV-resistance. The simple and green method for the preparation of microcapsules could have tremendous potential for the extensive development of wood protection.
