Manufacturing method of high-stability type solid wood composite floors

The invention relates to a method for preparing high-stability type solid wood composite floors. The preparation method comprises the following steps: (1) preparation of base materials: selecting wood veneers of which the moisture is 6 to 12 percent; sequentially carrying out the steps of glue distribution, blank grouping, cold pressing and hot pressing to obtain the base materials, wherein the blank grouping adopts an odd-even symmetrical way, specially, odd layers adopt the wood veneers of which elements are all the same while even layers adopt the wood veneers of which elements are all the same and the elements comprise moisture rate, texture , the variety of trees and thickness; (2) carrying out surface overlaying; (3) forming a mortise; (4) carrying out surface coating; and (5) carrying out edge sealing treatment. The high-stability type solid wood composite floors manufactured by the invention have low release amount, uniform moisture rate and good size stability; moreover, the waterproof resistance is
