Abstract

The wear-resistant plywood comprises a core board, wherein a plurality of uniformly distributed flanges are arranged on the upper surface and the lower surface of the core board; a carbon fiber layer is arranged above the core plate; a buffer layer made of rubber is arranged below the core plate; the wear-resistant layer is connected with the upper surface of the carbon fiber layer through the bonding layer; the bottom plate layer pass through the tie coat with the lower surface of buffer layer links to each other, the wear-resisting plywood of this practicality adopts to be equipped with the one deck wearing layer on the surface layer board and through having better adhesion degree, therefore enable the plywood to have better wearability, in addition, be equipped with the carbon fiber layer that has better intensity and the rubber layer that has cushioning effect from top to bottom at the core, therefore, can also make whole plywood have the structural strength and the buffering effect of preferred, because certain elasticity has, make to a certain extent alleviate the impact to the plywood surface, excellent in use effect, therefore, better practicality has, and is suitable for popularization and application.

Description

Wear-resisting plywood

Technical Field

The utility model relates to an wood-based plate technical field specifically is a wear-resisting plywood.

Background

The plywood is one of common furniture materials, is one of three large plates of an artificial plate, and can also be used as a material for airplanes, ships, trains, automobiles, buildings, packing boxes and the like.

A group of veneers are typically assembled and glued perpendicular to each other in the direction of the adjacent layers of wood grain, and the skins and inner sheets are typically symmetrically disposed on either side of the center layer or core.

The glued veneers are pressed into a plate blank which is formed by criss-cross matching of the glued veneers according to the wood grain direction under the condition of heating or not heating, and the glued veneers need to be applied to places which have certain frictional contact with the external environment, such as floors, pedals and the like, but most of the surface layers of the used glued veneers do not have wear resistance at present, so the service life is short, and the mechanical strength is not good, thereby the actual use effect is influenced.

Disclosure of Invention

The utility model aims at providing a wear-resisting plywood just in order to solve above-mentioned problem.

The utility model discloses a following technical scheme realizes above-mentioned purpose: the wear-resistant plywood comprises a core board, wherein a plurality of uniformly distributed flanges are arranged on the upper surface and the lower surface of the core board, and a carbon fiber layer is arranged above the core board; a buffer layer made of rubber is arranged below the core plate; the wear-resistant layer is connected with the upper surface of the carbon fiber layer through the bonding layer; the bottom plate layer is connected with the lower surface of the buffer layer through the bonding layer.

Preferably, the bonding layer is urea-formaldehyde resin glue.

Preferably, the wear-resistant layer is made of aluminum oxide and has a thickness of 1-2 mm.

Preferably, the flanges are hemispherical or conical or elongated in appearance, and the outermost contour apex of the flange protrudes from the core plate surface by not less than 2 mm.

Preferably, the thickness of the carbon fiber layer is 2.5-3 mm.

Preferably, the thickness of the buffer layer is 1-1.5 mm.

Advantageous effects

The utility model has the advantages that:

the utility model discloses a wear-resisting plywood adopts to be equipped with the one deck wearing layer on the surface layer board and through having better adhesion degree, therefore enable the plywood and have better wearability, in addition, be equipped with the carbon fiber layer that has better intensity and the rubber layer that has the cushioning effect from top to bottom at the core, therefore still can make whole plywood have the structural strength and the buffering effect of preferred, because certain elasticity has, make to a certain extent alleviate the impact to the plywood surface, the result of use is better, therefore, better practicality has, and is suitable for popularization and application.

Drawings

FIG. 1 is a front view of the structure of the present invention;

in the figure: 1-core plate, 2-buffer layer, 3-bonding layer, 4-bottom plate layer, 5-flange, 6-wear layer and 7-carbon fiber layer.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings and embodiments, which are to be understood as illustrative only and not limiting the scope of the invention. It should be noted that, in the following description, the words "front", "back", "left", "right", "upper" and "lower" are used, the words "left", "right", "upper" and "lower" refer to directions in the drawings, the words "front" and "back" refer to directions toward or away from the geometric center of a specific component, respectively, and in combination with the drawings in the embodiments of the present invention, the technical solution in the embodiments of the present invention is clearly and completely described, it is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments.

Please refer to fig. 1, which is a wear-resistant plywood of the present embodiment, including a core board 1, wherein a plurality of flanges 5 are uniformly arranged on both upper and lower surfaces of the core board 1, the flanges 5 are in a hemispherical shape, a conical shape or a strip shape, so as to increase the bonding strength with the upper and lower layers, the vertex of the outermost contour of the flange 5 protrudes from the surface of the core board 1 by not less than 2mm, and a carbon fiber layer 7 is arranged above the core board 1, and has a thickness of 2.5-3mm, preferably 3 mm; a buffer layer 2 made of rubber is arranged below the core plate 1, the thickness is 1-1.5mm, 1.5mm is preferred, the buffer effect is better after the buffer layer is arranged, but the buffer layer is 1.5mm in combination with actual conditions.

The top of the plywood is provided with a wear-resistant layer 6 with the thickness of 1-2mm, the wear-resistant layer 6 is made of alumina, and the wear-resistant layer 6 is connected with the upper surface of a carbon fiber layer 7 through a bonding layer 3;

the top of this plywood is equipped with bottom plate layer 4, and bottom plate layer 4 links to each other with buffer layer 2's lower surface through tie coat 3.

Two tie coat 3 all adopt the material to glue for urea-formaldehyde resin about, and it has good thermal stability and durability to glue of this material, improves life.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
