Abstract

Abstract:

Objective: The aim of this study was to investigate the effects of antibacterial agent treatment processes on the anti-blue stain bamboo scrimber and to provide technical support for its outdoor applications. Method: In the paper, the 3-iodo-2-propynyl butylcarbamate(IPBC) was used as an antibacterial agent. The anti-blue stain properties of bamboo scrimber manufactured by the soaking IPBC/soaking process, the soaking IPBC/coating process, and bamboo scrimber soaking in the IPBC process were studied through the indoor laboratory method and outdoor exposure test. Meanwhile, the scanning electron microscope(SEM), laser scanning confocal microscope(LSCM) and computed tomography(CT) were applied to investigate the distribution of IPBC in the bamboo fiber bundles and bamboo scrimber manufactured by the soaking IPBC/coating process. Result: The indoor experimental results showed that the grade of infected blue stain of the control sample and the bamboo scrimber manufactured by soaking IPBC/soaking process reached 4 level, while those of the bamboo scrimber manufactured by the soaking IPBC/coating process and bamboo scrimber soaking in the IPBC process reached 1 and 0 level, respectively. The outdoor exposure test was carried out in high humidity environments of Chengdu, Sichuan Province. The results indicated that the blue stain occurred on the surface of the control sample, the bamboo scrimber manufactured by soaking IPBC/soaking process and bamboo scrimber soaking in the IPBC process for about two months. Whereas, no blue stain occurred on the surface of the bamboo scrimber manufactured by the soaking IPBC/coating process for a duration of 12 months. The antibacterial agent was found in the cracks, parenchyma cells, vessels, intercellular cracks et al., which was confirmed by CT and LSCM result. The anti-blue stain efficiency of the bamboo scrimber manufactured by the soaking IPBC/coating process was due to the uniform distribution of IPBC in the bamboo fiber bundles, the formation of phenol-formaldehyde resin film on the bamboo fiber bundles enclosed the IPBC in the bamboo scrimber, which formed an effective fixation system of the PF resin during the curing process at high temperature, and then it acted as an antibacterial agent inhibitor and decreased the loss of antibacterial agent. Conclusion: The bamboo scrimber manufactured by soaking IPBC/coating process could be efficient for the prevention and amelioration of the blue stain and could be wildly used in outdoor environments.

Key words: blue stain, bamboo scrimber, antibacterial agent, 3-iodo-2-propynyl butylcarbamate(IPBC)
