Application of nano SiO 2 -IPBC microcapsules in the anti-mildew and UV- resistance of rubber wood

Abstract

Recent advances addressing the development of anti-mildew and UV-resistance microcapsules for wood. IPBC 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 fraction of nano SiO2-IPBC microcapsules, IPBC and the control group. Different FTIR characterizations and surface color 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 would have tremendous potential for the extensive development of wood protection.
