Abstract

Medium density fiberboard is a kind of man-made board made of wood fiber or other plant fiber, which is crushed, separated and dried, then applied with urea formaldehyde resin or other applicable adhesives, and then hot pressed. As MDF is a kind of composite material made of natural biomass materials, its internal nutrients are rich, and it is vulnerable to microbial erosion and mildew. The strains causing MDF mildew mainly include Aspergillus niger, Trichoderma viride, Penicillium tangerine, etc. The surface of MDF shows black or dark green mildew spots after mildew, which reduces its decorative performance and use performance, pollutes the living environment, and causes serious economic losses and waste of resources. Studies have shown that when the fungal spores in the air reach a certain concentration, indoor residents or workers will have allergies, asthma and other respiratory diseases. Therefore, the research and development of wood-based composites with antimildew function is of great value to improve the quality of living environment, prolong the service life of wood products and improve the comprehensive utilization rate of wood. In this study, a new mold inhibitor was added to the glue solution to prepare fiberboard. The effects of the addition of mold inhibitor on the physical and mechanical properties and mold resistance of fiberboard were investigated. The results showed that the viscosity of the resin system decreased with the increase of the amount of the two mold inhibitors. With the increase of the amount of mold inhibitor, the internal bonding strength, elastic modulus and static bending strength of the plate decreased in varying degrees. However, the addition of mold inhibitor significantly improves the mold resistance of the plate. The addition of mold inhibitor A is more conducive to the control of Trichoderma viride, while the addition of mold inhibitor B is more conducive to the control of Aspergillus niger. The amount of mold inhibitor B is appropriate at about 2%-3%. This study provides a new possible way for the application of new mold inhibitor in MDF, and has good practical significance.
