AI Technical Summary
Technical Problem
Existing bamboo anti-mildew agents have problems such as high toxicity and easy loss, making it difficult to meet health and environmental protection requirements. In addition, traditional laccase has low catalytic efficiency, resulting in insufficient anti-mildew properties.
Method used
Hydrothermal pretreatment is used to enhance the porosity of bamboo cell walls and improve lignin accessibility. Then, laccase is used to catalyze the modification of bamboo cell walls with natural antibacterial phenols to fix antibacterial components and improve anti-mildew efficacy.
Benefits of technology
It significantly improves the anti-mildew efficacy and anti-leaking properties of bamboo, meets environmental and safety requirements, and is suitable for "bamboo-based plastic" products.

Abstract
This invention discloses a method for improving the anti-mildew properties of bamboo, relating to the field of bamboo protection technology. The method first increases the lignin concentration on the surface of bamboo cell walls through hydrothermal pretreatment, and then synergistically modifies the bamboo cell walls with natural antibacterial phenols catalyzed by laccase. This synergistic treatment process increases the accessibility of laccase to lignin in bamboo cell walls, improving the catalytic modification efficiency by 30%. After treatment, the anti-mildew efficiency of the modified bamboo can reach 100%.
