Environment-friendly high-strength lignocellulose plate and preparing method thereof

The invention discloses an environment-friendly high-strength lignocellulose plate and a preparing method thereof. The preparing method of the environment-friendly high-strength lignocellulose plate comprises the following steps that firstly, plant raw material pretreatment is conducted, lignocellulose powder with the size smaller than 40 meshes is directly taken, or, plant raw materials rich in lignocellulose fiber are utilized for conducting flash explosion treatment, and the lignocellulose fiber is obtained, wherein the size of the plant raw materials rich in lignocellulose fiber ranges from 2 meshes to 80 meshes; secondly, the lignocelluloses fiber is mixed with a bonding agent, and the bonding agent is PVA and/or gelatin; thirdly, paving is conducted; fourthly, hot pressing is conducted; and fifthly, cooling forming is conducted. The preparing method of the environment-friendly high-strength lignocellulose plate is simple in process, usage of reagents such as acid and alkali is avoided in the whole proce
