Description

A kind of capsule wallboard of effective barrier low-frequency noise
Technical field
The present invention relates to construction industry wall body structure fields, and in particular to a kind of capsule wallboard of effective barrier low-frequency noise.
Background technology
The discernmible sound of ear of the mankind is within the scope of 15 hertz to 20,000 hertz.In general, Ren Leiyong Within the scope of the various sound of exchange are at 200 hertz to 8000 hertz, 200 hertz of sound below are bass, Wherein to the more apparent frequency of body effect, the predominantly frequency range of 3-50Hz.High frequency noise with distance it is remoter or Barrier is met with, can be decayed rapidly, such as the point sound source of high frequency noise, every 10 meters of distances can decline 6 decibels.And low frequency noise Successively decrease very slow, sound wave is again longer, can pass through barrier easily, long range long-range raid and transmural through walls directly enter human ear.Although low frequency Noise is apparent not as high frequency noise to directly affecting for human physiology, but it but will generate health long-range influence, Amplitude of the low frequency noise in antinode is most strong, and the physiology and mental health harm to people are most heavy.It is tired that psychological impact, which mainly shows, Disturb, and influenced mainly in relatively strong Sound stimulat on physiological, can cause middle ear constriction, otalgia, tympanic membrane injury, tinnitus and Headache, Nausea and vomiting, dysequilibrium, dimness of vision etc. also have been reported that infrasonic sound makes blood pressure, the rhythm of the heart, breathing anomalous variation occur, All there is detrimental effect in terms of to auditory system, nervous system, cardiovascular system, digestive system and metabolic function.
Wallboard generally uses multiple layers of different materials stepped construction at present, has also effectively obstructed 200 hertz or more of middle height Frequency noise, but bass barriering effect is barely satisfactory always.
Invention content
The technical problem to be solved in the present invention is to provide a kind of capsule wallboards of effective barrier low-frequency noise, pass through capsule battle array The three-dimensional photonic crystal structure of row, the micro mist in capsule vibrate in noise especially low-frequency noise transmittance process, consume Noise energy, it is effective to remove senior middle school's low frequency noise in conjunction with the sandwich of traditional multiple layers of different materials.
The invention is realized by the following technical scheme:
A kind of capsule wallboard of effective barrier low-frequency noise, includes the fire prevention resistance of sandwich layer, sandwich layer both sides made of PU expanded materials It is metal faced on the outside of damping layer and damping layer made of combustible material, at least one layer of capsule array, glue are spread in the sandwich layer The micro powder granule object of the 20-30% of intracapsular portion filling capsule cavity volume, micro powder granule object by two kinds of different-grain diameters A micro mists and B Micro mist mixes.
The present invention is further improved scheme, and the capsule diameter is d, and the spacing between capsule is D, then d≤D≤5d; The A grain size of micropowder is 80-200 mesh, and B grain size of micropowder is 2-3 times of A grain size of micropowder, and A micro mist quality accounts for overall micro mist quality 85-95%.According to use environment, the packing ratio of capsule array and micro powder granule object is adjusted, reaches isolation different frequency characteristic noise Purpose.
The further improvement project of the present invention is uniformly dispersing when the capsule array is single layer.
The further improvement project of the present invention is, when the capsule array is one layer or more, each layer capsule alternating expression arrangement. Core layer thickness thickness is staggered using multiple tier array, and soundproof effect is more preferably.
The further improvement project of the present invention is that capsule cortex is made of pvc material, micro powder granule in capsule Object is glass microballoon or solid waste material micro mist.
The further improvement project of the present invention is that the face layer uses aluminium sheet or iron plate.
Compared with prior art, the present invention having following obvious advantage:
The present invention is the sound-proofing for enhancing wallboard by the sandwich that multiple layers of different materials constructs from overall structure Can, wherein by the three-dimensional photonic crystal structure of capsule array structure, further eliminates the low frequency that sandwich cannot be separated and make an uproar Sound, the micro powder granule in capsule vibrate in noise especially low-frequency noise transmittance process, effectively consume low-frequency noise energy Amount.
