Abstract

The invention discloses a method for modifying bamboo wood materials and a bamboo wood board, belonging to the field of bamboo wood materials. The invention discloses a method for modifying bamboo and wood materials. Under the action of a high-voltage electrostatic field of 20KV to 60KV, high-voltage electrostatic treatment is performed on a bamboo and wood board body with silver plates pasted on its upper and lower ends. The sheet material modified by the present invention sequentially comprises a nano-silver element permeation layer, a bamboo wood plate body, and a nano-silver element deposition layer / nano-silver element permeation layer along the thickness direction of the sheet material. The bamboo wood material modified by high-voltage static electricity in the present invention has a deeper anticorrosion and mildew-proof treatment depth, and the penetration depth of the nano-silver element inside the board is 0.05 mm to 1 mm, and the anti-corrosion and mildew-proof effect of the modified bamboo wood material is more stable .

Description

Technical field [0001] The present invention belongs to the field of bamboo materials, and in particular, to a biosaterial modification method and a bamboo wood plate. Background technique [0002] Wood and bamboo are all natural polymer materials, since ancient times, has been widely used in humans. Today, the scientific and technological is highly developed, although many new materials are endless, wood and bamboo are in a very important role in people's lives with their own advantages and natural, beautiful textures in people's lives. However, as a biological material, wood and bamboo have its natural defects, it is easy to be bacteria, insects, marine drilling, and these shortcomings limit their application. Anti-corrosion is an important measures to extend the life of wood and bamboo, it is important. From macro, anti-corrosion treatment for wood and bamboo can reduce economic activities and people's lives to wood and bamboo demand, reduce forest cutting, protect forest reso...
