Preparation method of high-performance oriented structural plate and oriented wood chip composite laminated wood

The invention discloses a preparation method of a high-performance oriented structural plate and oriented wood chip composite laminated wood, and the high-performance oriented structural plate is obtained by using long-size poplar wood shavings through the processes of full-longitudinal paving, high compression ratio, continuous hot pressing and the like. And the oriented wood chip composite laminated wood is further prepared by laminating the oriented wood chip composite laminated wood serving as a base material or compounding and laminating the oriented wood chip composite laminated wood with other structural sawn timber. The longitudinal paving consistency of the flakes of the high-performance oriented structural plate reaches 70% or above, and the mechanical indexes of the high-performance oriented structural plate are detected according to GB/T 28993-2012 four-point bending: the longitudinal bending strength is 70 Mpa or above, the longitudinal elastic modulus is 11000 Mpa or above, and the internal bond
