Abstract

The invention discloses a bamboo mildew-proof treatment method. The method includes: drying bamboos until the moisture content is 12.5-14wt%, and ultrasonically treating in water to obtain a bamboo material A; treating the bamboo material A for 60-100min under vacuum of 0.06-0.1MPa to obtain a bamboo material B; adding the bamboo material B into a protecting agent, and treating for 30-45min underthe pressure of 2-2.5MPa to obtain a bamboo material C; well mixing zinc acetate, copper acetate and methyl alcohol, heating to 45-55 DEG C, dropwise adding methanol solution of sodium hydroxide, stirring for 10-25min, cooling, aging, soaking the bamboo material C to treat for 10-20min, and drying to obtain a bamboo material D; mixing zinc nitrate hexahydrate, copper nitrate, hexamethylenetetramine, polyethylene glycol and water, adding the bamboo material D, and performing hydrothermal reaction, washing and drying. The bamboo mildew-proof treatment method is simple in process, and treated bamboos are high in mildew-proof effectiveness and long in mildew-proof time.

Description

technical field [0001] The invention relates to the technical field of bamboo, in particular to a method for treating mildew of bamboo. Background technique [0002] Bamboo is hard, flexible, tensile, and compressive, and has a short growth cycle and strong renewability. It is an ideal alternative resource to alleviate the contradiction between wood supply and demand. It has been widely used in indoor and outdoor furniture, construction, decoration, and musical instruments. and automobile manufacturing. However, bamboo is rich in nutrients such as sugar, protein and fat, and it is prone to mildew and decay during storage, transportation and use, which not only causes waste of resources but also endangers human health, severely limiting its application. Multiple anti-mildew treatment methods have been disclosed at present, but generally have the defect that the effect is not good enough. Contents of the invention [0003] Based on the technical problems in the background ...
