Abstract

The utility model discloses a kind of China fir circuit board, its drip irrigation device is: comprise central layer, and be arranged on top plate and the bottom plate of central layer both sides, the top layer that described top plate comprises sound absorbing layer and fits with sound absorbing layer both sides respectively, described lower plywood comprises weedtree layer, and described weedtree layer both sides are equipped with top layer; This China fir circuit board has certain intensity, and has the effect of sound-absorbing and sound insulation, and soundproof effect can not be made due to problem of aging can not to reduce along with the time.

Description

China fir circuit board
Technical field
The utility model relates to a kind of plank, and more particularly, it relates to a kind of China fir circuit board.
Background technology
Chinese fir board utilizes short and small material long by referring to joggle, spells the large format heavy-gauge sheeting of wide synthesis.It generally adopts high-quality timber (more is with China fir at present, so be commonly called as Chinese fir board) as base material, to be made through techniques such as high temperature degreaser drying, finger, jigsaw, sandings.Which overcome some sheet material and use a large amount of glue, bonding operational characteristic.At present, this product is widely current the medium-to-high grade finishing in western developed country and China big and medium-sized cities, is also one of dalle of the most environmental protection of interior decoration simultaneously.Chinese fir board, is again China fir circuit board, China fir finger-jointed plate.
Market there are some sound insulating panels rubber layer, damping material or deadening felt etc. are installed between the two plates to make, adopt in this way, soundproof effect can be improved to a certain extent in short-term, but its soundproof effect can reduce gradually along with the time; As everyone knows, the materials such as rubber in atmosphere can be slowly aging, causes it hardening gradually and lose elasticity, thus causing soundproof effect to reduce gradually along with the time; On the other hand, this way of installing rubber layer or sound insulation carpet veneer in the middle of two boards, construction costs is also very high, and need to ensure in the occasion of inner tonequality at some, sound insulation only can prevent sound wave from spreading out of, cause external noise, and the density of sound insulating panel is higher, inner acoustic reflection can cause the both poor sound quality of inner occasion.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of China fir circuit board, and this Chinese fir board has certain intensity, and has the effect of sound-absorbing and sound insulation, can ensure inner tonequality while preventing noise unofficial biography.
For achieving the above object, the utility model provides following technical scheme: a kind of China fir circuit board, comprise central layer, and be arranged on top plate and the bottom plate of central layer both sides, the top layer that described top plate comprises sound absorbing layer and fits with sound absorbing layer both sides respectively, described lower plywood comprises weedtree layer, and described weedtree layer both sides are equipped with top layer.
The utility model is set to further: described puigging is made up of steel plate.
The utility model is set to further: described sound absorbing layer is made up of mineral wool material.
The utility model is set to further: the face that described top layer contacts with air is provided with overlay coating.
The beneficial effects of the utility model:
1, central layer can ensure the intensity of plate, sound wave can absorb by the sound absorbing layer formed by arranging bulk material, thus make this plate can be used in noise and need to ensure the occasion of inner tonequality, and by the setting of sound absorbing layer, the transmission of sound wave can be weakened, and in central layer inside, puigging is set again, thus soundproof effect is made to become better.
2, by the setting of steel plate and two central layer interlayers, make the intensity of plate higher, and steel plate be provided with very large soundproof effect, thus make its soundproof effect better, and its intensity can be strengthened, make sheet material more durable, and there will not be the phenomenons such as aging, soundproof effect variation.
3, mineral wool have light weight, coefficient of thermal conductivity little, do not burn, the feature such as mothproof, inexpensive, corrosion-resistant, chemical stability is good, sound absorbing capabilities is good, adopt it can the combination property of reinforcement plate as sound absorbing layer; The setting of overlay coating can be user-friendly to.
Accompanying drawing explanation
Fig. 1 is the structure chart of the utility model China fir circuit board embodiment.
Reference numeral: 1, central layer; 11, steel plate; 12, Chinese fir board; 2, top plate; 21, top layer; 22, sound absorbing layer; 3, bottom plate; 31, weedtree layer.
Detailed description of the invention
With reference to Fig. 1, the utility model Chinese fir board embodiment is described further.
As shown in Figure 1, a kind of China fir circuit board, comprise central layer 1, and be arranged on top plate 2 and the bottom plate 3 of central layer 1 both sides, the top layer 21 that described top plate 2 comprises sound absorbing layer 22 and fits with sound absorbing layer 22 both sides respectively, described lower plywood comprises weedtree layer 31, and described weedtree layer 31 both sides are equipped with top layer 21; Described central layer 1 comprises steel plate 11 and is close to the Chinese fir board 12 of steel plate 11 both sides.
Central layer 1 can ensure the intensity of plate, sound wave can be absorbed by arranging sound absorbing layer 22, thus make this plate can be used in noise and need to ensure the occasion of inner tonequality, and pass through the setting of sound absorbing layer 22, the transmission of sound wave can be weakened, thus make soundproof effect become better.
Described sound absorbing layer 22 is made up of mineral wool material; The face that described top layer 21 contacts with air is provided with overlay coating.
By the setting of steel plate 11 and two central layer 1 interlayers, make the intensity of plate higher, and steel plate 11 be provided with very large soundproof effect, thus make its soundproof effect better, and its intensity can be strengthened, make sheet material more durable, and there will not be the phenomenons such as aging, soundproof effect variation; Mineral wool have light weight, coefficient of thermal conductivity little, do not burn, the feature such as mothproof, inexpensive, corrosion-resistant, chemical stability is good, sound absorbing capabilities is good, adopt it can the combination property of reinforcement plate as sound absorbing layer 22; The setting of overlay coating can be user-friendly to.
Preferably, between each layer described, adopt wood glue to bond, HY-106AB glue also can be adopted to bond, adopt the bonding resistance to elevated temperatures that can improve plank of this glue.
The above makes preferred embodiment of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
