Abstract
The invention relates to a glass cotton elastic acoustic board, which comprises a frame, wherein the periphery of the frame is provided with a surface layer; and three base material layers are arranged in the frame, consist of a glass cotton board, a glass cotton felt and a glass cotton board respectively and are seamlessly adhered with one another. The acoustic board has the advantages of wide adsorption spectrum, high sound absorption coefficient and excellent sound absorption effect on low-frequency, intermediate-frequency and high-frequency noise. Compared with the domestic similar products, the acoustic board has the advantages of extremely high sound absorption coefficient, particularly high elasticity at the low frequency of 100-315HZ, but the domestic similar products hardly have elasticity.
Description
Technical field
The present invention relates to a kind of glass wool elasticity abatvoix.
Background technology
Most in the market engineerings all be with glass wool or rock wool as sound absorption material, all are the raw materials of shape of loosing, not only long in time limit, the trouble of so direct form of construction work does not meet environmental protection, labour protection condition yet.The acoustically effective of existing a few glass wool abatvoix is not ideal enough at home, especially to the low frequency noise reduction, makes that the low frequency reverberation time is long, and hall tonequality is ambiguous.
Summary of the invention
The purpose of this invention is to provide a kind of noise to low frequency, intermediate frequency, high frequency all has the glass wool elasticity abatvoix of splendid sound-absorbing effect.
The objective of the invention is to be achieved through the following technical solutions:
A kind of glass wool elasticity abatvoix comprises frame, and described frame periphery is provided with the top layer, in establish three layers of base material, described three layers of base material are respectively block of glass wool, blanket of glass wool, block of glass wool, three layers of mutual seamless bonding of base material.
Beneficial effect of the present invention is: the abatvoix absorption spectrum is wide, and the sound absorption coefficient height all has splendid sound-absorbing effect to the noise of low frequency, intermediate frequency, high frequency.With domestic like product relatively, sound absorption coefficient of the present invention exceeds a lot, low frequency (100-315HZ) elasticity preferably especially, and domestic like product does not almost have elasticity.
Description of drawings
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is the structural representation of the described a kind of glass wool elasticity abatvoix of the embodiment of the invention.
Among the figure:
1, top layer; 2, frame; 3, base material; 31, block of glass wool; 32, blanket of glass wool; 33, block of glass wool.
The specific embodiment
As shown in Figure 1, the described a kind of glass wool elasticity abatvoix of the embodiment of the invention comprises frame 2, described frame 2 peripheries are provided with top layer 1, in establish three layers of base material 3, described three layers of base material 3 are respectively block of glass wool 31, blanket of glass wool 32, the 3 mutual seamless bondings of 33, three layers of base material of block of glass wool.
The effect of base material 3: as independent use blanket of glass wool 32, though flexible, because it is softer, product is difficult to moulding, and outward appearance is bad and low frequency absorption is bad.As independent use block of glass wool 31,33, because it is harder, there is not elasticity, influence the acoustically effective of medium-high frequency.With the use that combines of block of glass wool 31,33 and blanket of glass wool 32, can remedy the defective that it uses alone, existing outward appearance preferably has elasticity preferably again, and sound-absorption coefficient is improved greatly.
The effect of frame 2: make compound base material 3 fixed-type.
Top layer 1: can make by various fabrics.Base material 3, frame 2 are wrapped tightly.Its interface connects with linear slit or glue cements.Making sound enter base material 3 smoothly is absorbed; Base material 3 and frame 2 are fixed together; The dust that prevents glass fiber flies out; Provide a good outward appearance to product, make the user that the impression an of U.S. be arranged.
Claims (1)
1. glass wool elasticity abatvoix, comprise frame (2), it is characterized in that: described frame (2) periphery is provided with top layer (1), establish three layers of base material (3) in the frame (2), described three layers of base material (3) are respectively block of glass wool (31), blanket of glass wool (32), block of glass wool (33), the mutual seamless bonding of three layers of base material (3).
