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.
According to the oxidation treatment of the anticorrosion mildew-proof environment-friendly artificial board based on the biomass charcoal, the biomass charcoal powder is added into sulfuric acid with the concentration of 98%, ultrasonic dispersion is carried out at room temperature for 30-45min, the biomass charcoal powder is uniformly dispersed in the sulfuric acid, then condensation reflux reaction is carried out in an oil bath at the temperature of 80-90 ℃ for 2-2.5h, after the reaction is finished, natural cooling is carried out to the room temperature, deionized water is added for dilution, finally, an organic filter membrane is adopted for suction filtration and washing until the pH value of filtrate is neutral, and a product obtained by suction filtration and washing is placed into a drying oven for drying, so that oxidized biomass charcoal is obtained.

Comparative example: taking a conventional anticorrosion and mildewproof artificial board sold in the market.
The artificial boards of examples 1 to 11 and the artificial boards of the comparative example were processed into 2 samples of 50mm × 20mm × 5mm, the first sample was placed in a petri dish with aspergillus niger, trichoderma viride and penicillium citrinum, the fungal infection area of the artificial board was counted by a number square method after being placed at 25 ℃ for 30 to 35 days, and the mildew-proof effect was expressed by the percentage of the infected area, the second sample was placed in a petri dish with white rot fungi, the artificial board was tested for mass loss at 25 ℃ for 30 to 35 days, and the corrosion resistance was expressed by the erosion mass loss rate, and finally the data shown in table 1 were obtained:
TABLE 1
As can be seen from Table 1, the artificial board of the invention has excellent anti-corrosion and anti-mildew effects, and compared with the conventional anti-corrosion and anti-mildew artificial board, the anti-corrosion and anti-mildew artificial board has the advantages that the mildew infection area on the surface of the artificial board is greatly reduced, and the quality loss rate of the artificial board is also greatly reduced under the corrosion of white rot fungi. As can be seen from the data in the comparative examples, the effects of the present invention are more remarkable in examples 10 and 11, this is because, since the biomass char before oxidation is agglomerated due to its high surface energy, even if the biomass char in the biomass char-soaking solution is dispersed by the dispersant, it is also difficult to uniformly disperse in the biomass charcoal soaking solution, is not beneficial to adsorbing the preservative and the mildew preventive, and the hydroxyl on the surface of the oxidized biomass charcoal can provide negative charges, thereby generating long-term charge stability, so that the oxidized biomass charcoal is stably dispersed in the biomass charcoal soaking agent, the preservative and the mildew preventive are adsorbed on the whole area, thereby achieving the best adsorption effect, leading the antiseptic and mildew-proof biomass charcoal in the follow-up artificial board to release the antiseptic and mildew-proof agent for a longer time, and further prolonging the service life of the artificial board.
The artificial boards obtained in examples 1 to 11 and the artificial board of the comparative example were further left standing in an open room for 15 days to detect the components of the air in the room by using a gas detector, and the contents of formaldehyde and toluene (unit: mg/m) in VOC were mainly detected3) The results are shown in table 2:
TABLE 2
As is apparent from table 2, the contents of formaldehyde and toluene in the detected VOCs in examples 1 to 11 of the present invention are far less than those in the comparative example, because biomass charcoal is added to the adhesive, and then the adhesive is used to process the artificial board, the artificial board is prepared by using the mixture of the adhesive and the biomass charcoal, and because the biomass charcoal has a strong adsorption capacity, the VOCs generated in the adhesive or the VOCs in the air can be absorbed by the biomass charcoal, on the one hand, the problem of VOC release from the adhesive can be fundamentally solved, and therefore, the present invention can effectively block the VOC release from the artificial board, thereby effectively reducing indoor air pollution and improving living environment. It can be seen from the examples 10 and 11 that the contents of formaldehyde and toluene in VOC are substantially the lowest and the effect is the best, because the present invention oxidizes the surface of the biomass charcoal by using the oxidation treatment, the surface of the oxidized biomass charcoal has a wrinkle phenomenon, and the surface area of the oxidized biomass charcoal is enlarged, so the biomass charcoal can be in better contact with gas, and is beneficial to adsorbing harmful gases such as formaldehyde in the adhesive, thereby the effect of removing the harmful gases in the artificial board in advance from the source of the adhesive is realized, and the artificial board has more safety.
In conclusion, the invention not only can keep the anti-corrosion and anti-mildew effects for a long time and prolong the service life of the artificial board, but also can reduce VOC (volatile organic compounds) release, reduce indoor air pollution and improve the living environment.
