Description
Technical field
The invention belongs to automobile mechanical field, be specifically related to the ceiling of a kind of high sound absorption properties.
Background technology
Along with society is growing, client is tightened up to the requirement of car load NVH performance, and the automotive trim of high sound absorption qualities becomes the target of development, and as the ceiling design that NVH performance contribution amount is very big, its high sound absorption properties requires to be particularly important.
The automobile ceiling structure of present stage is followed successively by bottom non-woven fabrics, glass+glue, PU plate, glass+glue, fabric from bottom to top, the ceiling design of this employing monolayer PU plate is not ideal to sound absorption properties, therefore, those skilled in the art is devoted to the ceiling developing a kind of desirable high sound absorption qualities, to improving NVH performance, the satisfaction promoting passenger just seems extremely important.
Summary of the invention
For solving the problems referred to above, the invention discloses the ceiling of a kind of high sound absorption properties, to be used for solving the problem that ceiling attractability is undesirable.
For reaching above-mentioned purpose, technical scheme is as follows:
A kind of ceiling of high sound absorption properties, including finish coat and sound absorbing layer, described finish coat includes nonwoven layer and interior finish coat, described nonwoven layer ground floor located above, interior finish coat is positioned at bottom surface, described sound absorbing layer includes glass rubber layer, PU plate one, Corii Bovis seu Bubali epoxy adhesive layer, PU plate two and glass epoxy adhesive layer, described glass rubber layer is positioned at below nonwoven layer, PU plate one and PU plate two are set under glass rubber layer, arranging Corii Bovis seu Bubali epoxy adhesive layer between described PU plate one and PU plate two, PU plate arranges glass epoxy adhesive layer two times.
As a modification of the present invention, described nonwoven layer thickness is thicker than interior finish coat.
As a modification of the present invention, the Corii Bovis seu Bubali in described Corii Bovis seu Bubali epoxy adhesive layer is bar shaped, and width is less than 8 millimeters.
As a modification of the present invention, described finish coat is hot-forming with sound absorbing layer, and gap is less than 0.1 millimeter.
As a modification of the present invention, the thickness of described glass rubber layer, Corii Bovis seu Bubali epoxy adhesive layer and glass epoxy adhesive layer is lower than PU plate one and PU plate two.
As a modification of the present invention, the density of described PU plate one is more than the density of PU plate two.
The invention has the beneficial effects as follows:
The ceiling of a kind of high sound absorption properties of the present invention, utilize multiple structure hot-forming, gap is less than 0.1 millimeter, each lamination is tightly integral, and the Corii Bovis seu Bubali in Corii Bovis seu Bubali epoxy adhesive layer is bar shaped, not only increases the safety of roof of the vehicle, more enhance the noise reduction of roof of the vehicle, the density of PU plate one is more than the density of PU plate two, and different densities can absorb the noise of different frequency range, enhances decrease of noise functions.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Reference numerals list:
1. nonwoven layer, 2. glass rubber layer, 3.PU plate one, 4. Corii Bovis seu Bubali epoxy adhesive layer, 5.PU plate two, 6. glass epoxy adhesive layer, finish coat in 7..
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, it is further elucidated with the present invention, it should be understood that following detailed description of the invention is merely to illustrate the present invention rather than restriction the scope of the present invention. It should be noted that, the word "front", "rear" of use is described below, direction that "left", "right", "up" and "down" refer in accompanying drawing, word " interior " and " outward " refer respectively to the direction towards or away from particular elements geometric center.
As shown in the figure, a kind of ceiling of high sound absorption properties, including finish coat and sound absorbing layer, described finish coat includes nonwoven layer 1 and interior finish coat 7, described nonwoven layer 1 ground floor located above, interior finish coat 7 is positioned at bottom surface, described sound absorbing layer includes glass rubber layer 2, PU plate 1, Corii Bovis seu Bubali epoxy adhesive layer 4, PU plate 25 and glass epoxy adhesive layer 6, described glass rubber layer 2 is positioned at below nonwoven layer 1, glass rubber layer arranges PU plate 1 and PU plate 25 for 2 times, between described PU plate 1 and PU plate 25, Corii Bovis seu Bubali epoxy adhesive layer 4 is set, PU plate arranges glass epoxy adhesive layer 625 times, utilize multiple structure, not only increase the safety of roof of the vehicle, more enhance the noise reduction of roof of the vehicle.
As shown in the figure, described nonwoven layer 1 thickness is thicker than interior finish coat 7, the thickness of glass rubber layer 2, Corii Bovis seu Bubali epoxy adhesive layer 4 and glass epoxy adhesive layer 6, lower than PU plate 1 and PU plate 25, utilizes PU plate 1 and the noise-absorbing function of PU plate 25, can be effectively reduced the noise in automobile.
As it can be seen, the Corii Bovis seu Bubali in described Corii Bovis seu Bubali epoxy adhesive layer 4 is bar shaped, width is less than 8 millimeters, it is possible to uniformly mixes with epoxy glue, and can increase toughness.
As it can be seen, described finish coat is hot-forming with sound absorbing layer, gap is less than 0.1 millimeter, and each lamination is tightly integral, more enhances security performance when strengthening anti-acoustic capability.
As it can be seen, the density of PU plate 1 is more than the density of PU plate 25, different densities can absorb the noise of different frequency range, enhances decrease of noise functions.
As shown in the figure, first nonwoven layer 1 sprayed liquid rubber and sprinkle glass, PU plate 1 sprays Corii Bovis seu Bubali on epoxy glue uniform spreading, PU plate 25 sprays epoxy glue and sprinkles glass, then by nonwoven layer 1, PU plate 1 and PU plate 25 stack hot-forming with interior finish coat 7, and last water is cut into the ceiling of high sound absorption properties.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned embodiment, also includes the technical scheme being made up of above technical characteristic combination in any.
