Abstract

The invention discloses a bamboo / wood antiseptic, a preparation method thereof and a treating method for modifying bamboo / wood by using the antiseptic. The antiseptic comprises a camphortree leaf water extract and urea-formaldehyde resin, wherein the percentage concentration by mass of the camphortree leaf water extract is 5-10 percent, and the solid content of the urea-formaldehyde resin is 40-60 percent. The antiseptic contains the camphortree leaf extract, and serves as a natural environmentally-friendly antiseptic without heavy metal or any toxic or side effect on people and livestock; and corrosion-resistant wood / bamboo prepared with the method has a remarkable antiseptic effect, high anticorrosion performance, mold preventing and controlling efficiencies of up to 75-50 percent and stain mold preventing and controlling efficiencies of up to 50-25 percent, and meets the requirement of level II (corrosion resistant level) specified in the national standard GB / T13942.1-1992.

Description

technical field

[0001] The invention relates to an infiltration liquid for impregnating wood / bamboo, a preparation method of the infiltration liquid, a preparation method using the infiltration liquid and a treatment method for impregnating wood / bamboo with the infiltration liquid, in particular to an antiseptic liquid and a preparation method thereof And utilize this preservative solution to process wood / bamboo wood method. Background technique

[0002] As a biological material composed of natural polymer compounds, wood / bamboo has the advantages of high strength-to-weight ratio, low processing energy consumption, and relatively small environmental pollution. And the deficiency of being destroyed by the infringement of microorganisms.

[0003] Traditional wood / bamboo preservative treatment can effectively improve wood / bamboo corrosion resistance to a certain extent and prolong the service life of wood / bamboo, but traditional wood / bamboo preservative treatment can improve t...
