Be provided with the sound insulation cavity that thickness is the cotton layer of 1/2nd PP in the middle part of the cotton layer of described PP, in described sound insulation cavity, be provided with polyurethane alveolar layer.
Described butyl layers is provided with the PE film that one deck covers butyl layers.
Compared with prior art, the beneficial effects of the utility model are as follows:
By arranging butyl layers and can effectively reduce the vibrations of roof of the vehicle in the utility model, utilize butyl rubber heat-resisting, ageing-resistant, chemical-resistant resistance, and have the performances such as shock-absorbing, and on butyl rubber, be coated with PE film prevent from butyl rubber from gluing note cannot removing to ceiling, by arranging terylene needled felt under butyl layers, sponge foaming, PP cotton and micro fiber leather can utilize the performance of the sound insulation damping of terylene needled felt greatly, the performance of the sound insulation noise reduction of sea foaming, the cotton good springiness of PP, bulkiness is strong, good muffling effect, micro fiber leather has wear-resisting, ventilative, ageing-resistant, environmental protection and the advantage such as outward appearance is beautiful, micro fiber leather improves the practicality of sound insulating pad further, the utility model structure is simple, easy to usely to be worth of widely use.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation with the automobile roof sound insulation cushion of damping and silencing.
In figure, 1 is butyl layers; 2 is terylene needled felt layer; 3 is sponge foaming layer; 4 is the cotton layer of PP; 5 is micro fiber leather layer; 6 is sound insulation cavity; 7 is polyurethane foam; 8 is PE film.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.
As shown in Figure 1, technical solution adopted in the utility model is: a kind of automobile roof sound insulation cushion with damping and silencing, and in order to reach the object of damping, use butyl layers 1 for buffer layer in this case, butyl rubber can be heat-resisting, resistance to ozone, ageing-resistant, chemical-resistant resistance, and have shock-absorbing, electrical insulation capability, makes full use of the buffer layer of damping as this case of butyl rubber in this case, wherein in order to improve the cushioning effect of automobile roof sound insulation cushion, be also arranged with terylene needled felt layer 2 at butyl layers 1, and terylene needled felt is through having good sound insulation, the effect of sound-absorbing and damping, arranges and can improve damping and noise reduction further under butyl rubber, the effect of sound insulation, in order to put forward sound insulation erasure effect further, be arranged with sponge foaming layer 3 at terylene needled felt layer 2, sponge foaming layer 3 has good sound insulation, damping, environmental protection, fire-retardant and formability, in order to further put forward the sound insulation value of sound insulating pad, is arranged with the cotton good springiness of the cotton layer 4, PP of PP at sponge foaming layer 3, bulkiness is strong, be not afraid of the characteristic of extruding, there is the general character of good sound insulation damping, wherein in order to improve environmental protection and the practicality of sound insulating pad further, micro fiber leather layer 5 is arranged with at the cotton layer 4 of PP, wherein, the cotton layer 4 of butyl layers 1, terylene needled felt layer 2, sponge foaming layer 3, PP and micro fiber leather layer 5 all bonding by melmac, use melmac to be the anti-flammability improving product further in this case.
As shown in Figure 1, the sound insulation cavity 6 that thickness is the cotton layer 4 of 1/2nd PP is provided with in the middle part of the cotton layer 4 of PP, wherein sound insulation cavity 6 can by emitting noise, thus reach environmental protection sound insulation, intercept and reflection sound insulation, be provided with polyurethane alveolar layer 7 in sound insulation cavity 6, polyurethane foam be set and be more conducive to sound insulation and damping; In order to prevent butyl rubber and ceiling bonding from cannot remove, PE film 8, PE film butyl layers 1 being provided with one deck covering butyl layers plays buffer action.
Compared with prior art, the beneficial effects of the utility model are as follows:
