According to the biomass charcoal-based anticorrosion mildew-proof environment-friendly artificial board, the preservative is one of ammonia-soluble alkyl cuprammonium, copper azole, 1, 2-benzisothiazolin-3-one or copper dimethyldithiocarbamate.

In the biomass charcoal-based anticorrosive mildew-proof environment-friendly artificial board, the mildew preventive is one of mildewproof azole and 8-hydroxyquinoline copper or boride.

In the anticorrosion, mildewproof and environment-friendly artificial board based on the biomass charcoal, the dispersant is one of sodium carboxymethylcellulose, or glyceryl tristearate.

According to the biomass charcoal-based anticorrosion mildew-proof environment-friendly artificial board, the wood adhesive base material is one of soybean protein adhesive, phenolic resin adhesive or white latex.

After the step a, the biomass charcoal based anticorrosive, mildewproof and environment-friendly artificial board is further subjected to oxidation treatment on the biomass charcoal powder, and the oxidized biomass charcoal is used in the step c.

In the above-mentioned artificial board based on biomass charcoal, the oxidation treatment is carried out by irradiating biomass charcoal powder with an irradiation intensity of 0.35w/m²and (3) oxidizing for 72-96h under the irradiation of an at 340nm xenon arc lamp.
