Abstract
The invention discloses a sound-absorbing board which comprises a frame, a sound absorption layer and non-woven cloth, wherein the sound absorption layer sequentially comprises a centrifugal glass cotton layer and a rock cotton layer from top down; the sound absorption layer is surrounded by the frame; the non-woven cloth is arranged on the upper side of the centrifugal glass cotton layer and the lower side of the rock cotton layer; and the frame is made of a density board with round holes in front and rear surfaces. According to the sound-absorbing board, the centrifugal glass cotton layer and the rock cotton layer which both have good sound-absorbing effect cooperate with each other, so that the sound-absorbing board is better in sound-absorbing property; meanwhile, the frame adopts the density board with the round holes in the front and rear surfaces, so that the sound-absorbing property of the sound-absorbing board is further improved; and the sound-absorbing board has good sound-absorbing effect and is worthy of popularization.
Description
Technical field
The present invention relates to a kind of sheet material, be specifically related to that a kind of sound-absorbing effect strengthens sheet material.
Background technology
Now, noise pollution has become influences people able-bodied one big harm source, noise can influence people's hearing, cause negative effects such as hearing impairment, headache, noise can also bring out multiple disease simultaneously, lives, works and learn for people normally and make troubles, therefore, people are more and more higher to the requirement of residing architectural environment sound-absorbing effect, just are necessary to design a kind of sound absorption material that can highly effectively absorb incident acoustic wave.
Summary of the invention
In order to solve problems of the prior art, the invention provides a kind of abatvoix, the centrifugally glass-wool layer has superior acoustical absorbance properties, the rock wool layer has good sound insulation and acoustical absorbance properties, cooperatively interacting of the two makes this abatvoix have stronger sound-absorbing effect, simultaneously, frame adopts sound-absorbing effect hole wood abatvoix preferably, has further strengthened the sound absorption qualities of this abatvoix.
A kind of abatvoix is characterized in that: comprise frame and sound absorbing layer, described sound absorbing layer comprises centrifugally glass-wool layer and rock wool layer from top to bottom successively, and described frame is centered around around the sound absorbing layer.
Aforesaid a kind of abatvoix is characterized in that: also comprise nonwoven, described nonwoven is arranged on the upside of centrifugally glass-wool layer and the downside of rock wool layer.
Aforesaid a kind of abatvoix is characterized in that: described centrifugally glass-wool layer and rock wool layer are bonded together by glue-line.
Aforesaid a kind of abatvoix is characterized in that: described frame is made by hole wood abatvoix.
The invention has the beneficial effects as follows: a kind of abatvoix provided by the invention, dual sound-absorbing effect by centrifugally glass-wool layer and rock wool layer, make this abatvoix have stronger acoustical absorbance properties, frame adopts the hole wood abatvoix with good sound-absorbing character to make, and has further strengthened the attraction characteristic of this abatvoix.
Description of drawings
Fig. 1 is the structural representation of abatvoix of the present invention.
The mark implication of accompanying drawing is as follows:
1: frame; 2: the rock wool layer; 3: the centrifugally glass-wool layer; 4: nonwoven.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of abatvoix, comprise frame 1, sound absorbing layer and nonwoven 4, sound absorbing layer comprises centrifugally glass-wool layer 3 and rock wool layer 2 from top to bottom successively, centrifugally glass-wool layer 3 has superior acoustical absorbance properties, rock wool layer 2 has good sound insulation and acoustical absorbance properties, cooperatively interacting of the two makes this abatvoix have stronger sound-absorbing effect, centrifugally glass-wool layer 3 and rock wool layer 2 are bonded together by glue-line, simple to operate, materials are cheap, save production cost, and nonwoven 4 is arranged on the upside of centrifugally glass-wool layer 3, be between centrifugally glass-wool layer 3 and the upper side frame, nonwoven 4 also is arranged on the downside of rock wool layer 2, and promptly between rock wool layer 2 and the lower frame, being provided with of nonwoven 4 effectively prevents the unrestrained of rotary glass cotton fiber and rock wool fiber, stablize the acoustical absorbance properties of this abatvoix, frame is centered around around the sound absorbing layer, and frame made by the hole wood abatvoix with good sound-absorbing effect, has further increased the acoustical absorbance properties of this abatvoix.
A kind of abatvoix provided by the invention, cooperatively interact by centrifugally glass-wool layer and the rock wool layer that all has good sound-absorbing effect, make this abatvoix have stronger attraction characteristic, simultaneously, frame adopts hole wood abatvoix, further strengthened the acoustical absorbance properties of this abatvoix, sound-absorbing effect is good, is worthy to be popularized.
More than show and described basic principle of the present invention, principal character and advantage.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
