Embodiment 1

[0029] Embodiment 1: The manufacturing method of thermoplastic resin wood composite board comprises several layers of wooden rotary-cut veneer and plastic film, and plastic film is polyethylene new film, and veneer and plastic film are arranged alternately to form slab, and plastic film can be 1 in every layer Sheets, or several sheets can be stacked together to form a glue layer. The combined slabs are sent to a hot press for hot pressing, and then quickly sent to a cold press for cold pressing. The hot pressing temperature is greater than or equal to that of the wood composite board. Plastic film melting temperature, pressure 1-50kg / cm 2 , the hot pressing time is greater than or equal to the melting time of the plastic film in the wood composite board, and the cold pressing pressure is 1-50kg / cm 2 , The wooden composite slab is released from the hot press to the cold press for less than 2 minutes, and the molten thermoplastic resin is condensed and hardened by cold pressing...

Embodiment 2

[0030] Embodiment 2: other is the same as embodiment 1, but hot pressing temperature is 140-180 ℃.

Embodiment 3

[0031] Embodiment 3: Others are the same as in Embodiment 2, but the time for the wooden composite board to be pushed out from the hot press to the cold press is 1-60 seconds.
