The utility model provides a composite artificial board, this composite artificial board can be arranged in the indoor environment, and this composite artificial board can improve the noise reduction effect that gives sound insulation of current composite artificial board.
Referring to fig. 1, in an embodiment of the artificial composite board 10 of the present invention, the artificial composite board 10 is a layered structure, and the artificial composite board 10 includes a wood veneer layer 100 and a metal plate layer 200. Wherein, the wood veneer layer 100 has at least two layers; the metal plate layer 200 is arranged between two adjacent wooden veneer layers 100, the metal plate layer 200 is a magnesium metal plate, and the wooden veneer layers 100 and the metal plate layer 200 are bonded into a whole through an adhesive 300.
Specifically, the metal plate layer 200 is a magnesium metal plate having a characteristic of high damping performance, and the magnesium metal plate is one of a magnesium plate and a magnesium-zirconium alloy plate, wherein the magnesium plate is an industrial grade pure magnesium metal plate having a purity of 99.8% or more, and the magnesium-zirconium alloy plate is a Mg-0.6Zr alloy plate. The magnesium metal plate can weaken the bending vibration strength of the composite artificial board 10, and when the composite artificial board 10 generates bending vibration, the vibration energy is rapidly transmitted to the magnesium metal plate tightly adhered to the wood veneer layer 100, so that the friction and the mutual dislocation inside the magnesium metal plate are caused. Because of the large internal friction and the large internal consumption of the magnesium metal plate, a part of the vibration energy of the composite artificial board 10 is converted into heat energy and dissipated, thereby weakening the bending vibration of the composite artificial board and reducing the vibration noise radiation of the composite artificial board 10. When the requirement for the sound insulation performance of the artificial composite board 10 is high, the magnesium metal board and the wood veneer layer 100 may be sequentially adhered at intervals to be composited together, so as to meet the requirement for sound insulation, that is, the wood veneer may be two, three or more layers, which will be described in detail later.
Further, the artificial composite board 10 has a layered structure, when sound waves are incident on the surface of the artificial composite board 10, the sound waves undergo a process of one reflection and transmission on each layer of the artificial composite board 10, and reflected waves and transmitted waves are reflected and transmitted between the magnesium metal plate and the wood veneer layer 100 for many times, so that energy of the sound waves is greatly consumed, and the purposes of sound insulation and noise reduction are achieved. For the noise in the middle and low frequency range, the magnesium metal plate can reduce the vibration amplitude of the composite artificial board 10 and weaken the resonance phenomenon, and for the noise in the high frequency range, the magnesium metal plate makes the fit valley become shallow, thereby improving the sound insulation and noise reduction effects of the composite artificial board 10. Under the critical frequency, due to the high damping effect of the magnesium metal plate in the two adjacent wood veneer layers 100, the two wood veneer layers 100 are separated from each other, the sound insulation amount of the composite structure can reach the sum of the sound insulation amounts of the two wood veneers, and compared with the method of increasing the thickness of the wood composite artificial board 10, the composite artificial board 10 formed by adding the magnesium metal plate for laminar composite has a better sound insulation effect.
In addition, the composite artificial board 10 is formed by bonding the wood veneer layer 100 and the metal veneer layer 200 into a whole through the adhesive 300, when the composite artificial board 10 is assembled, the metal veneer layer 200 coated with the adhesive 300 and the wood veneer layer 100 are sequentially bonded together in a criss-cross manner according to the grain direction of the wood veneer, and then the bonded composite artificial board 10 is sent into a hot press for hot pressing and curing.
It can be understood, to having the same thickness the utility model discloses a compound wood-based plate 10 and current wooden compound wood-based plate, because of high damping material magnesium metal sheet and the special syllable-dividing principle of wooden veneer, make the utility model discloses a compound wood-based plate 10's syllable-dividing effect is better, under the same syllable-dividing requirement of indoor environment promptly, the utility model discloses a compound wood-based plate thickness is thinner, has also solved current wooden compound wood-based plate bulky and occupation space's problem appears.
The technical scheme of the utility model, through setting up wooden veneer layer 100, wooden veneer layer 100 has two-layerly at least, and locate between the adjacent two-layer wooden veneer layer 100 with metal sheet layer 200, wooden veneer layer 100 bonds through adhesive 300 with metal sheet layer 200 and becomes integrative, metal sheet layer 200 is the magnesium metal board, the magnesium metal board has the high characteristic of damping performance for wooden board, the magnesium metal board can reduce composite wood-based plate 10's vibration range, weaken resonance phenomenon, through the composite wood-based plate 10 that forms magnesium metal board and wooden veneer layer 100 complex, compare with the wooden composite wood-based plate 10 of current looks isostructure, the utility model discloses a noise reduction effect that gives sound insulation of composite wood-based plate 10 is better. Therefore, the utility model discloses a composite artificial board 10 has improved the noise reduction effect that gives sound insulation of current composite artificial board 10.

When the adhesive is coated, any one of phenol resin, urea resin, melamine resin or vinyl acetate resin may be coated on one side of the wood veneer layer 100 facing the metal plate layer 200, or may be coated on both sides of the metal plate layer 200 facing the wood veneer layer 100, and only the adhesive 300 needs to firmly bond the adjacent wood veneer layer 100 and the metal plate layer 200.
Referring to fig. 1, in an embodiment, in order to improve the sound insulation and noise reduction effects of the artificial composite board 10, the thicknesses of two adjacent wood veneer layers 100 are optionally different. The thickness through with wooden veneer layer 100 sets up to mutually unequal size for composite wood-based plate 10 is asymmetric setting, can weaken the resonance phenomenon that the sound wave caused like this, to the noise in the high frequency range, makes the identical millet shallow, is favorable to improving composite wood-based plate 10's syllable-dividing noise reduction effect.
