The wood-plastic composite board according to claim 1, wherein: the sealing plate is characterized in that side edge insertion blocks (10) are arranged on two sides of the sealing plate (9), a middle insertion block (11) is arranged in the middle of the sealing plate (9), the middle insertion block (11) is inserted into the corresponding middle slot (6), and the side edge insertion blocks (10) are inserted into the corresponding side edge slots (5).
3. The wood-plastic composite board according to claim 2, wherein: the sealing plate (9) is integrally formed with a side edge insertion block (10) and a middle insertion block (11) thereon.
4. The wood-plastic composite board according to claim 1, wherein: go up wood and mould composite sheet (1) and first L type buckle (4) and set up for integrated into one piece, wood is moulded composite sheet (3) down and is set up for integrated into one piece with second L type buckle (2).
5. A processing technology of the wood-plastic composite board as claimed in claim 1, which is characterized in that: the method specifically comprises the following steps:
s1, mixing the mixture of the plant fiber, the vinyl chloride plastic and the graft plastic, the polyolefin resin, the foaming regulator, the stearic acid, the azobisisobutyronitrile, the pigment, 2-3 parts of the flame retardant, the mildew preventive, the silane coupling agent and the compatilizer, stirring at the rotating speed of 320 revolutions per minute for 10-15 minutes, and injecting into a mold after stirring uniformly;
s2, putting the board into a hot press, and hot-pressing the board for 3-5 min at the temperature of 170-190 ℃ and under the pressure of 0.5-2 MPa to obtain a semi-finished board;
s3, placing the semi-finished plate in a cold press, cooling to below 60 ℃ under the pressure of 0.4-1.5 MPa, taking out the semi-finished plate from the cold press, placing the semi-finished plate in a greenhouse for steam curing, maintaining the temperature of the greenhouse at 40 ℃ for 8 hours to obtain the upper wood-plastic composite plate (1), and preparing the lower wood-plastic composite plate (3) by adopting the same method.
