Eucalyptus plate modifying method

The invention discloses a eucalyptus plate modifying method which comprises the following steps: preparing a modifying agent; impregnating a eucalyptus plate; and carrying out drying, polymerization and modification. According to the eucalyptus plate modifying method, chitosan is easy to dissolve in a weak-acid solvent; particularly, a solution obtained after the dissolution contains amidogen (NH2+), and amidogen is bonded with a negative electron so as to inhibit bacteria, so that the anti-corrosion property of the eucalyptus plate can be effectively improved by bonding the modifying agent which contains the chitosan component with the eucalyptus plate; furthermore, chitosan has a significant characteristic of adsorbing capacity, that is, chitosan is capable of adsorbing and discharging heavy metal, so that the environment can be purified and the harm to the human body can be reduced; and accordingly, when the modifying agent which contains chitosan is bonded with the eucalyptus platethrough the eucalyptus p
