Abstract
The utility model relates to a noise-reducing water-blocking film of an automobile, which is provided with a noise-reducing water-blocking film body. One side of the noise-reducing water-blocking film body is provided with a sound absorbing layer. In the noise-reducing water-blocking film, hot-melt glue is used for firmly sticking polyester fiber sound-absorbing cotton and the water-blocking film body, therefore, for the automobile noise transferred into a door, a great part of the sound-wave energy is consumed in the polyester fiber sound-absorbing cotton, and the noise is converted into heat energy in the multilayered polyester fiber sound-absorbing cotton with porous gaps, so that the sound-insulating and noise-reducing effects are better.
Description
Technical field
The utility model relates to a kind of auto sound waterproof part, particularly a kind of automobile noise reduction dash film.
Background technology
Along with developing of automobile industry, people to the travelling comfort of car and vibrationproof, every make an uproar and performance requriements such as waterproof more and more higher.Arrangements for automotive doors is baroque parts, car door all is to be made by sheet metal on the one hand, part noise (as engine noise, tire noise) can be by vehicle body panel beating and framework transfer of vibration in the operator's compartment, and these noises can drive the car door metal vibrating plate in transmittance process, produce the secondary noise, the normal dash film of pasting plays sound insulation between car door inboard and the vehicle door interior trim panel, the effect of damping can reduce penetrating of external heat again; Automobile dash film is installed on the circuit normal operation that is used in the arrangements for automotive doors protect in the arrangements for automotive doors on the other hand, prevents extraneous rainwater, and dust etc. enter, and prolongs the service life of spraying paint in the top layer.
The general-utility car dash films that adopt are gone up in the car door design of present many vehicles more, have played sound insulation a little, the effect of damping; One sidecar Men Jun is equipped with the vehicle window that slidably opens and closes, one slat gum bar is arranged between glass for vehicle window and the door outside sheet metal component, the one, waterproof, the 2nd, the position that keeps glass for vehicle window, this is that car door leaks, dust and noise enter a weak link in the car door body; Noise during automobile is advanced makes the people feel tired and carsick.Therefore general-utility car dash film can not satisfy the requirement that battle wagon requires obviously to reduce noise.
The utility model content
The purpose of this utility model provides a kind of above-mentioned shortcoming that overcomes, and the sound insulation and noise reduction effect is automobile noise reduction dash film preferably.
The technical scheme that realizes the utility model purpose is: a kind of automobile noise reduction dash film, have the dash membrane body, and described dash membrane body one side is provided with sound absorbing layer.
The sound absorbing layer of above-mentioned automobile noise reduction dash film is the poly-ester fibres acoustical cotton, by hot melt glue and dash membrane body fixed bonding.
The utlity model has positive effect: the utility model is in dash membrane body relevant position, with hot melt glue poly-ester fibres acoustical cotton and dash membrane body are pasted firmly, automobile imports most of the consumption in the poly-ester fibres acoustical cotton of acoustic wave energy of the noise in the car door into like this, noise has been transformed into heat energy in the poly-ester fibres acoustical cotton in multi-layer porous gap, the sound insulation and noise reduction effect is better.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and according to specific embodiment also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 part sectional view.
The specific embodiment
See Fig. 1 and Fig. 2, the utlity model has dash membrane body 1, dash membrane body 1 is the PVC film, and dash membrane body 1 one sides are provided with sound absorbing layer 2, and described sound absorbing layer 2 is the poly-ester fibres acoustical cotton, by hot melt glue 3 and dash membrane body 1 fixed bonding.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is a specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
1. an automobile noise reduction dash film has dash membrane body (1); It is characterized in that: described dash membrane body (1) one side is provided with sound absorbing layer (2).
2. automobile noise reduction dash film according to claim 1, it is characterized in that: described sound absorbing layer (2) is the poly-ester fibres acoustical cotton, by hot melt glue and dash membrane body (1) fixed bonding.
