Abstract
The utility model discloses a double-layer surface perlite lightweight waterproof sound absorbing board which comprises a perlite base and strengthening meshes; the strengthening meshes are respectively arranged in the middle of the perlite base and two corresponding rock surfaces of a perlite, wherein, one rock surface is also provided with a waterproof layer which is tightly connected with the rock surface; the waterproof layer is provided with a sound absorbing hole, the depth of which is more than the thickness of the waterproof layer, and the bottom part of which is connected with the strengthening meshes. The strengthening mesh in the middle of the perlite base is fiberglass mesh fabrics and the strengthening meshes on the two rock surfaces are fiberglass mats. As the double-layer surface perlite lightweight waterproof sound absorbing board is provided with three layers of strengthening meshes, the rock surface layer is provided with a waterproof coating layer, and the waterproof layer is externally provided with the sound absorbing hole which can penetrate through the strengthening meshes, the sound absorbing board has strong integrity and non-easy deformation and crack. Moreover, on the condition of guaranteeing the strength of the board, the proportion thereof can be significantly reduced and the sound absorbing coefficient thereof can be increased; the waterproof layer with the sound absorbing hole can not only effectively block the water vapor so as to prevent the perlite layer from deformation due to water absorption, but also does not reduce the effect of sound absorption.
Description
Technical field
The utility model belongs to building material technical field, especially relates to the high perlite sound absorption of a kind of lightweight protection against the tide, intensity and pulls.
Background technology
Perlite acoustical board sound absorbing capabilities is good, but intensity is low, easy deformation and fracture, and it is low yield rate when not only producing, and is unfavorable for installing and using; For improving product strength, reduce breakage, the method for taking to strengthen product density that has though play certain effect, has reduced porosity, has reduced the product sound absorption coefficient; The mode of the employing reinforcing mat that also has has played certain effect to distortion, but anti-fracture effect is undesirable.
Summary of the invention
The technical problems to be solved in the utility model provides that a kind of proportion is little, intensity is high, protection against the tide and the good perlite acoustical board of sound-absorbing effect.
For solving the problems of the technologies described above, the utility model comprises perlite basic unit and reinforcing mat, its design feature is in the middle of perlite basic unit and relative two scars are equipped with reinforcing mat, also be provided with the waterproofing course of close proximity with it on one of them scar, this waterproofing course is provided with the sound absorption hole, the sound absorption hole depth is greater than waterproofing layer thickness, and its bottom joins with reinforcing mat.
The middle reinforcing mat of described perlite basic unit is a glass fiber mesh, and two scar reinforcing mats are glass mat.
Described waterproofing course is a dope layer, and its thickness is the 1-2 millimeter.
Because the utility model is provided with 3 layers of reinforcing mat, the scar layer is provided with the water-repellent paint layer outward, and waterproofing course is provided with the sound-absorption hole that is deep into reinforcing mat outward, and the acoustical board globality is strong, not yielding and broken, and under the situation that guarantees plank intensity, the proportion that can reduce significantly improves sound absorption coefficient, the waterproofing course that has the hole that absorbs sound, both can effectively block steam, prevent the suction distortion of pearl rock stratum, not reduce acoustically effective again.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is that side of the present utility model is cutd open schematic diagram.
Among the figure: 1, perlite basic unit, 2, reinforcing mat, 3, waterproofing course, 4, the sound absorption hole, 5, reinforcing mat in the middle of the basic unit.
The specific embodiment
By shown in Figure 1, this bilayer face pearlite light waterproof sound absorption is pulled and is comprised perlite basic unit 1, reinforcing mat in the middle of being provided with in the middle of the perlite basic unit 1, this centre reinforcing mat is a glass fiber mesh 5, on perlite basic unit 1 relative two scars, be provided with reinforcing mat 2, two scar reinforcing mats 2 are glass mat, on a scar of perlite basic unit 1, be provided with the waterproofing course 3 of close proximity with it, the thickness of this waterproofing course 3 is the 1-2 millimeter, can brush with latex paint, be provided with sound absorption hole 4 on the waterproofing course unevenly, sound absorption hole 4 degree of depth are greater than waterproofing course 3 thickness, and its bottom joins with reinforcing mat 2.
Claims (3)
