Preparation method of antibacterial and mold and rottenness proofing wooden fibers

The invention provides a preparation method of antibacterial and mold and rottenness proofing wooden fibers, and aims at solving the technical problems of small combining strength of the existing wooden cellulosic fibers with antibacterial and anticorrosive effects. The method comprises the steps of soaking the wooden fibers with an ethanol or diethanol amine solution; drying; soaking through an antibacterial and anticorrosive agent solution; drying to obtain the antibacterial and mold and rottenness proofing wooden fibers; the antibacterial and anticorrosive agent is SR-A-103 type antibacterial and anticorrosive agent or SR-O-M101 type antibacterial and anticorrosive agent; the elasticity modulus is up to 18000 to 1900MPa; the mechanical strength is improved; in addition, the process is simple; special devices are saved; the preparation method has the characteristics of being small in investment and economic and can be used for manufacturing fiber boards.
