The present application relates to the technical field of artificial board, and discloses a kind of mould-proof composite board for wardrobe and a preparation method thereof.The composite board for wardrobe prepared by the present application is prepared by using
rubberwood sheet as main
raw material, impregnating treatment with mould-proof and
antibacterial agent, and then
adhesive treatment with
adhesive containing mould-proof and
antibacterial agent.The composite board realizes long-term inhibition of mould through multi-mechanism sterilization of components, synergistic effect and material level protection, and is suitable for wardrobe application in high-
humidity environment.In addition, the use of mould-proof and antibacterial
adhesive also endows the composite board with excellent
bonding strength.
