Abstract

The utility model relates to a plywood, which is composed of a single board and a fiber board glued together. A surface layer is glued to the outer side surface of the fiber board, wherein, the single board is a thin plate rotatablely cut from a log. The fiber board is formed by wood chips, wood processing surplus chips and other logs with small diameters ground into wood fibers and adhesive is added to be pressed in high pressure, wherein, the wood fibers is in a multidirectional staggered shape. After glued and pressed in the high pressure, not only the strength is high but also the shaped surface is flat and no large manpower is consumed for the repairing work to enable the surface layer to be flatly attached.

Existing traditional laminated structure as shown in Figure 3, Figure 4, it is formed by stacking by three layers of veneer 40, veneer 40 is thin slices of rounding, and the grain direction of 40 of each adjacent veneers all is vertical mutually and is provided with, and the superficial layer 50 that is sticked on the veneer 40 of a side therein more thereafter gets final product.

But above-mentioned existing traditional glued board but has following shortcoming:

1, production cost height: because the veneer material is the rotary-cut thin slice of natural wood, and also in recent years owing to environmental consciousness comes back, and the cry of rescue rainforest is surging, the log price in the feasible whole world is improve relatively all, so can directly have influence on its production cost.

2, structural strength is not good: because the veneer material is the thin slice of log, and the intensity extreme difference of log thin slice itself, though the structure of existing conventional veneer boards is to be superimposed with each other with three layers of veneer, and make the grain direction between each adjacent veneer all be vertical mutually setting, though its structural strength has been enough to satisfy the purposes that provides as indoor compartment or decoration construction, but still can't bear bigger external force effect, its structural strength obviously still has some deficits.

3, superficial layer attaches out-of-flatness: because the surface of veneer wood has wood grain, so when superficial layer (superficial layer can be veneer, PVC or facing paper) when attaching thereon, except being not easy to adhere to, also be not easy smooth attaching.

This shows that still there are many defectives in above-mentioned existing glued board, and the assistant officer waits to be improved.Because the defective that above-mentioned existing glued board exists, the design people actively study innovation based on abundant practical experience and professional knowledge, through constantly studying, design, and after studying sample and improvement repeatedly, creates the utility model finally.

Main purpose of the present utility model is, overcome the defective that existing glued board exists, and provide a kind of cheap for manufacturing cost, smooth glued board attractive in appearance after structural strength height and superficial layer attach, make it be glued together by veneer and fiberboard to form, and superficial layer is the lateral surface that is attached at fiberboard, wherein veneer is the thin slice of rounding, fiberboard is with wood chip, the smaller diameter logs of timber processing residue material bits or artificial afforestration grinds to form wood fibre, and add stalemate agent after make by the high pressure pressing, utilize natural wood to make production cost so can save, and the wood chip of fiberboard inside, it is to be multidirectional staggered that the log than minor diameter of timber processing residue material bits or artificial afforestration grinds to form wood fibre, and stalemate agent can make polymerism therebetween better, pass through the pressing of high pressure again, structural strength height not only, and the surfacing after the moulding, the smooth attaching of superficial layer can be made thereon, and low cost of manufacture can be reached, the smooth effect attractive in appearance of structural strength height and superficial layer.

The purpose of this utility model is realized by following technical scheme.According to a kind of glued board that the utility model proposes, it is characterized in that this glued board is glued together and is integral by veneer and fiberboard, veneer is the rounding thin slice, fiberboard is to expect that with wood chip, timber processing residue the smaller diameter logs of bits and artificial afforestration grinds to form wood fibre, and be added with stalemate agent, be made for one via the high pressure pressing, the lateral surface of the fiberboard superficial layer that can be sticked.

The utility model compared with prior art has tangible advantage and good effect.By above technical scheme as can be known, the utility model glued board has the following advantages:

1, low cost of manufacture: its fiberboard is to expect that with wood chip, timber processing residue the log than minor diameter of bits or artificial afforestration grinds to form wood fibre, and form via high pressure pressing manufacturing again behind the interpolation stalemate agent, and be not that direct use natural timber raw material is made production, so production cost is low.

2, structural strength height: because the log than minor diameter of the wood chip of fiberboard inside, timber processing residue material bits or artificial afforestration grinds to form wood fibre is to be multidirectional staggered, and via after the interpolation stalemate agent, the polymerism that the log than minor diameter of wood chip, timber processing residue material bits or artificial afforestration grinds to form between the wood fibre is better, pass through the pressing and forming of high pressure again, make its structural strength height.

3, superficial layer is smooth attractive in appearance after attaching: because fiberboard itself is the moulding via the high pressure pressing, so the surfacing after its moulding does not have microgroove, so superficial layer also can be smooth is attached on the fiberboard.

In sum, the utility model is to be formed by veneer and fiberboard gummed, superficial layer is the lateral surface that is attached at fiberboard, wherein veneer is the rounding thin slice, fiberboard is to grind to form wood fibre with wood chip, timber processing residue material bits etc. than the log of minor diameter, and add stalemate agent after make by the high pressure pressing, and wherein wood fibre is to be multidirectional staggered, after deadlocked and high pressure pressing, intensity height not only, and the surfacing after the moulding, need not expend the work that great amount of manpower is done repairing, superficial layer can smoothly be attached.No matter it structurally or bigger improvement is all arranged on the function, and produced handy and practical effect, and have the enhancement effect really, thereby be suitable for practicality more, really is a new and innovative, progressive, practical new design.
