Problems solved by technology

Ordinary plywood can only be used as a plane, and cannot be bent into a certain shape or curvature. When these plywood is used in a structure with a curvature, more plywood is needed to splice, which wastes resources and takes time. , there are also bendable plywood in the prior art. These curved boards are mainly provided with slits on the face plate and bottom plate of the curved board. Under the condition of external heating, it is softened, and then bent and thermoset. There are gaps on the panel, which is not beautiful

Embodiment

[0026] As shown in the figure, a curved plate of the present invention is composed of a panel 1 and a middle panel 3. The panel 1 is arranged on the upper and lower sides of the middle panel 3, and the wood fiber lines of the panel 1 and the middle panel 3 are distributed crosswise. The panel 1 and the middle panel 3 One or more layers of core boards 2 are arranged in cooperation with each other, or no core board is provided, and the wood fiber texture of the core board 2 is the same as that of the panel 1 . The curved board of the present invention can be divided into a horizontal curved board and a long curved board. Distributed along the length direction (also can be veneer of any specification), the transverse curved plate is bent in the width direction, and the wood fiber grains of the long surface curved panel 1 and core plate 2 are distributed along the direction of length (also can be veneer of any specification), and the middle Board 3. The wood fiber grains are distr...

Abstract

The present invention provides a bending board and a manufacturing method thereof, which belongs to the technical field of veneer board. The bending board comprises surface boards and a middle board. The invention is characterized in that the upper surface and lower surface of middle board are set with surface boards precisely. Furthermore the wood fiber grain of surface board and wood fiber grain of middle board are distributed across. The manufacturing method comprises the following steps: selecting material, rotary cutting, board bending, drying, adhesive confecting, adhesive spreading, prepressing, hot pressing and grinding with sand. The bending board of the invention selects appropriate wood as raw material and executes strict board matching. The inherent fiber characteristic of wood is scientifically, reasonably and sufficiently. The bending board is bent randomly along with wood fiber. The manufacturing method is confirmed with an optimal adhesive confecting method after long-term experiment. The performance of bending board is more sufficiently represented through the approximate adding amount of solidifying agent and filling agent in adhesive confecting.

Description

technical field [0001] The invention belongs to the technical field of plywood, and in particular relates to a bendable plywood and a manufacturing method thereof. Background technique [0002] At present, plywood has been widely used for its superior performance, especially in the field of home decoration. Ordinary plywood can only be used as a plane, and cannot be bent into a certain shape or curvature. When these plywood is used in a structure with a curvature, more plywood is needed to splice, which wastes resources and takes time. , there are also bendable plywood in the prior art. These curved boards are mainly provided with slits on the face plate and bottom plate of the curved board. Under the condition of external heating, it is softened, and then bent and thermoset. There are gaps on the panel, which is not beautiful. SUMMARY OF THE INVENTION [0003] Aiming at the problems existing in the prior art, the present invention designs and provides a technical soluti...
