The specific embodiment
As illustrated in fig. 1 and 2, comprise according to sound absorption of the present utility model, noise elimination, sound insulation composite plate: absorbent treatment 1 is provided with a plurality of through holes 5 on absorbent treatment 1; Soundproof course 2, described soundproof course 2 is bonded together with absorbent treatment 1 by the adhesive layer 3 of polyurethane glue and so on, thereby forms cavity 4 at absorbent treatment 1 and soundproof course 2.Absorbent treatment 1 and soundproof course 2 can be mineral wool board well known in the art, polymerization vegetable fibre board or fiberboard, also can be the plates of being made by polyester material well known in the art.Preferably, described soundproof course is more smoothly closely knit with respect to absorbent treatment, and thicker, to strengthen soundproof effect.
As shown in Figure 3, the external surface 1a of absorbent treatment 1 can be rough surface, reducing the reflection to sound wave, thereby strengthens acoustically effective.Preferably, can the floral designs of create an aesthetic feeling on external surface 1a, with when strengthening acoustically effective, more pleasing.In addition, as shown in Figure 3, in order further to strengthen acoustically effective, can bond to the deadener 6 of glass wool, brown sheet and so on the inner surface of absorbent treatment 1 by cementing agent, and it is corresponding with cavity, perhaps also can bond on the part corresponding with cavity of inner surface of soundproof course 2, the thickness t of wherein said deadener is less than the height h of cavity.Thereby the periphery place near each side that the viscose glue of polyurethane glue and so on is coated on absorbent treatment 1 and soundproof course 2 forms adhesive layer 2 between absorbent treatment 1 and soundproof course 2, be defined as closed cavity 4 by absorbent treatment 1, soundproof course 2 and adhesive layer 3 like this, can be with glass wool attached in the hollow part, with further enhancing noise elimination effect.Alternatively, also can be coated on the viscose glue of polyurethane glue and so between absorbent treatment 1 and the soundproof course 2 with multiple spot and/or multi-thread form, between absorbent treatment 1 and soundproof course 2, form discontinuous adhesive layer 2 thus, between absorbent treatment 1, soundproof course 2 and adhesive layer 3, be defined as the cavity 4 of a plurality of openings like this, the deadener 6 of filling glass cotton and so in cavity 4.
Further preferably, be provided with parallel in the cavity 4 and it is divided into two-part dividing plate 7 with cavity 4, have aperture 8 on the dividing plate 7, and on the face relative of dividing plate 7, be bonded with deadener 6 with absorbent treatment 1 with soundproof course 2 and absorbent treatment 1.Deadener 6 is bonded on the dividing plate 7 like this, has promptly increased the steadiness of deadener, has also increased the soundness of whole composite plate, has also increased the acoustically effective of deadener 6 simultaneously.
In said structure,, therefore can improve absorptive capacity on absorbent treatment to noise because a plurality of through holes are set.And, owing to be provided with cavity between absorbent treatment and the soundproof course, rather than filled by polyamine fat glue material fully, therefore can improve acoustically effective.In addition, owing to, therefore compared by bonding by polyamine fat glue partly between absorbent treatment and the soundproof course with the situation that is coated with polyamine fat glue between the two fully, can economical with materials, reduce cost.In addition, can add materials such as glass wool by the roughness of change absorbent treatment external surface or at cavity, and further strengthen acoustically effective.
Although diagram has also illustrated embodiment more of the present utility model; but it will be appreciated by those skilled in the art that; do not depart from the protection domain that principle of the present utility model and spiritual essence, appended claims book limited and be equal to replacement, can also change these embodiments.
