Manufacturing method of laminated flooring

Abstract

The invention discloses a manufacturing method of laminated flooring. The method comprises the following steps: A) machining a groove on an untreated fiber board at a certain interval, so that a lateral wall of the groove and a walking surface of the untreated fiber board have a smooth transition; B) laying equilibrium paper, the untreated fiber board with machined grooves, grainy paper and wear-resistant paper on a lower die steel sheet of a hot press in turn, with an upper die steel sheet of the hot press being ribs matched with the grooves on the untreated fiber board; C) matching and hot pressing the upper die steel sheet of the hot press and the lower die steel sheet of the hot press to obtain a panel of the laminated flooring; D) displaying the panel of the laminated flooring; and E) cutting the panel along a central line of the grooves to obtain floor battens, and then cutting out a splineway along periphery of the cut floor battens. Compared with conventional molded laminated flooring, the laminated flooring made by the method has the advantages of higher chamfering prevision, higher internal bonding strength at the chamfer, and longer service life; compared with production by conventional methods, production by the method helps save 30% of die cost, thus reducing production cost.

Description

technical field [0001] The invention relates to a method for making reinforced wood flooring. Background technique [0002] Laminate flooring has gained a place in the wood flooring market due to its high wear resistance of the surface and its low price. In terms of appearance and function, laminate flooring has always imitated and pursued solid wood flooring. Chinese patent 03112761.4 discloses a laminated wood floor and its production method, which discloses the process and method of chamfering the laminated wood floor at the edges of both sides of the imitation solid wood floor. The technical scheme adopted is: Balance paper, fiberboard, wood grain paper and wear-resistant paper are laid on the lower mold steel plate. The upper mold steel plate of the hot press adopts a steel plate with multiple ribs. The abrasive paper is hot-pressed at one time, and at the same time, a groove that matches the rib is molded on the surface of the large board at one time, and then the la...

Problems solved by technology

However, after testing, we found that the internal bonding strength of the laminate flooring produced by this molding method is 10% lower than that of the plane at the chamfer. This is because the fiberboard itself has formed a stable and dense fiber structure. Rigid pressure on the upper mold steel plate of the convex rib will destroy its original organizational structure and reduce its strength; in addition, it is produced by molding method, and the wear-resistant paper, wood grain paper and fiberboard are pressed into V-shaped grooves at one time. Excessive deformation at the V-shaped groove will lead to cracking of
