Detailed Description

In order to make the objects, technical solutions and advantageous effects of the present invention more clearly understood, the following technical solutions of the present invention are further described with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 3, the present invention provides a fiberboard convenient for punching, which comprises a first composite layer 1 and a second composite layer 2 sequentially arranged from top to bottom, wherein the first composite layer 1 and the second composite layer 2 are bonded by an adhesive layer 3; the first composite layer 1 and the second composite layer 2 are both made of wood fibers or other plant cellulose fibers as raw materials. Due to the limitation of the processing technology, the lower surface of the fiber board is usually provided with the reticulate pattern, while the traditional fiber board is usually of an integral structure, so that when the lower surface of the fiber board absorbs moisture and deforms, the upper surface of the fiber board is also bent to different degrees; in the embodiment, the first composite layer 1 and the second composite layer 2 are relatively independent bodies, and when the second composite layer 2 absorbs moisture and deforms, the first composite layer 1 cannot deform along with the moisture and deformation; in addition, the second composite layer 2 has the moisture of subtotal to depend on the lower surface of viscose layer 3 after absorbing moisture, and viscose layer 3 can completely cut off the moisture of subtotal, and then can prevent to warp after first composite layer 1 absorbs moisture.

The inside of first composite bed 1 has two-layer linear array's through-hole 4, and two-layer through-hole 4 is staggered arrangement respectively, and the side around first composite bed 1 is run through to the through-hole 4 straight line to can guarantee that the drill bit can both contact with arbitrary one through-hole 4 when punching on the optional position. The presence of the through-holes 4 in the first composite layer 1 has several advantages: firstly, a part of raw materials can be saved, and the hardness of the first composite layer 1 can be reduced; secondly, when the drill bit passes through the through hole 4, the drill bit can directly penetrate through the through hole 4 without applying external force, so that labor is saved; thirdly, in the process of drilling, the edge of the punched hole is not easy to break due to the through holes 4 for dispersing the pressure applied on the first composite layer 1; fourth, during the drilling process, the friction between the drill and the first composite layer 1 generates a large amount of heat, which can be discharged through the through-holes 4 at an increased speed.

The second composite layer 2 comprises a plurality of groups of anti-bending blocks 20 which are arranged in parallel left and right, the adjacent anti-bending blocks 20 are pressed, the upper surfaces of the groups of anti-bending blocks 20 form the upper surface of the second composite layer 2, and the lower surfaces of the groups of anti-bending blocks 20 form the lower surface of the second composite layer 2. The multiple sets of anti-bending blocks 20 are arranged in parallel, so that the bending section coefficient of the second composite layer 2 on the horizontal plane can be increased, and the problem that the second composite layer 2 is warped and deformed due to the difference of expansion force generated after the lower surface of the second composite layer 2 absorbs moisture is solved.

Each group of anti-bending blocks 20 comprises a first fixing part 200 and a second fixing part 201 which are sequentially arranged from top to bottom, a groove 202 is formed in the lower surface of the first fixing part 200, a protrusion 203 matched with the groove 202 is formed in the upper surface of the second fixing part 201, and the first fixing part 200 and the second fixing part 201 are connected or bonded through the groove 202 and the protrusion 203 in a pressing mode. The first fixing portion 200, the second fixing portion 201, the groove 202 and the protrusion 203 can increase the bending section coefficient of the anti-bending block 20 in the vertical plane, and thus can prevent the second composite layer 2 from being deformed after moisture absorption.

The lower surface of the second composite layer 2 is coated with a waterproof layer 5, which can effectively prevent water from contacting with the lower surface of the second composite layer 2 and prevent the water from absorbing or decaying.

The upper surface of the first composite layer 1 is coated with the wear-resistant layer 6, which can prevent the first composite layer 1 from being scratched during transportation or construction.

This embodiment is through replacing the fibreboard of traditional overall structure by the fibreboard that comprises first composite bed 1 and second composite bed 2 to can solve the problem of fibreboard moisture absorption back deformation, arrange a plurality of through-holes 4 simultaneously in first composite bed 1, be convenient for punch the processing to the fibreboard.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
