Description
Technical field
The utility model relates to a kind of noise insulation equipment, particularly relates to a kind of complex sound insulation pad.
Background technology
As everyone knows, sound source is in the vibration of object, and vibration is propagated in atmosphere and just defined sound wave, and when sound wave incident is to body of wall or floor, body of wall or floor will be made also to produce vibrate and to external radiation.In daily life, modal is exactly that resident family is upstairs when walking, step can give floor impulsive force, this impulsive force is enough to make floor produce vibration, if the effectiveness in vibration suppression of floor is bad, footsteps will be delivered in the family of resident family downstairs by floor, wall, causes either large or small influence of noise.So our sound insulating pad of saying, should be cushion blocking strictly speaking.
Step upstairs, the wide frequency range involved by sound such as to speak, only use the sound-absorbing material of individual layer or acoustic material to be difficult to reach desirable effect.Simultaneously according to the propagation characteristic of sound wave, sound wave all can produce reflection, transmission when the material by different densities.
Utility model content
The purpose of this utility model is the defect of the soundproof effect difference overcoming existing sound insulating pad, provides a kind of complex sound insulation pad, adopts the puigging of different densities, effectively can completely cut off the propagation path of sound, effectively improves the sound insulation value of floor.
The utility model is achieved in that
A kind of complex sound insulation pad, comprises one or more layers low-density puigging, one or more layers Midst density puigging and one or more layers high density puigging, the arrangement of low-density puigging, Midst density puigging and high density puigging any combination.
Further, described complex sound insulation pad comprises one deck low-density puigging, one deck Midst density puigging and one deck high density puigging, in accordance with the order from top to bottom, is followed successively by low-density puigging, Midst density puigging and high density puigging.
Further, the gross thickness of low-density puigging, the gross thickness of Midst density puigging are all not identical with the gross thickness of high density puigging.
Further, the thickness of low-density puigging gross thickness, Midst density puigging and high density puigging is: the gross thickness of the gross thickness > high density puigging of the gross thickness > Midst density puigging of low-density puigging.
Further, the ratio of the gross thickness of the gross thickness of described low-density puigging, the gross thickness of Midst density puigging and density puigging is 4 ~ 7: 2 ~ 4: 1 ~ 3.5.
Further, the gross thickness of described low-density puigging is 4 ~ 7mm, and the gross thickness of Midst density puigging is 2 ~ 4mm, and the gross thickness of high density puigging is 1 ~ 3.5mm.
Further, the gross thickness of described low-density puigging is 5mm, and the gross thickness of Midst density puigging is 3mm, and the gross thickness of high density puigging is 2mm.
Wherein, the thickness of every layer of low-density puigging, Midst density puigging and high density puigging can consider according to its aspect such as the number of plies, slab thickness and determines.
Those skilled in the art should be realized that the density of the density < high density puigging of the density < Midst density puigging of low-density puigging.
Further, the density of described low-density puigging is 30 ~ 40kg/m
3, the density of described Midst density puigging is 35 ~ 45kg/m
3, the density of described high density puigging is 40 ~ 60kg/m
3.
Further, density puigging, Midst density puigging and high density puigging are polyethylene-butyl rubber mixed layer (polyethylene is with the material of butyl rubber mixing).
The utility model adopts the puigging of different densities, can effectively completely cut off the propagation path of sound, effectively improves the sound insulation value of floor, and while can be avoided echoing the generation of sound effectively.Adopt the floor of complex sound insulation pad of the present utility model to clash into defening effect and can improve more than 3-5 decibel than traditional sound insulating pad, thus protect our living space not by the interference of noise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to the accompanying drawings, in conjunction with specific embodiments the utility model is described further, to understand the utility model better.
With reference to Fig. 1, a kind of complex sound insulation pad, comprises three layers, in accordance with the order from top to bottom, is followed successively by low-density puigging 1, Midst density puigging 2 and high density puigging 3, is formed by high temperature automatic bonding.
Those skilled in the art should be realized that the density of the density < high density puigging 3 of the density < Midst density puigging 2 of low-density puigging 1.In the present embodiment, low-density puigging 1, Midst density puigging 2 and high density puigging 3 are polyethylene-butyl rubber mixed layer (polyethylene is with the material of butyl rubber mixing), and the density of described low-density puigging 1 is 30 ~ 40kg/m
3, the density of described Midst density puigging 2 is 35 ~ 45kg/m
