Background
In the running process of an automobile, noise and vibration can be generated outside or in the automobile, and in order to improve the comfort of people in the automobile, damping plates are adopted to filter vibration and absorb sound. At present, most of automobiles produced in China adopt an asphalt damping plate for damping, asphalt contains a large amount of volatile harmful gas, the smell is larger when the asphalt is heated, air in the automobile can be polluted, and the asphalt is greatly unfavorable for the health of drivers and passengers in the automobile. The sound absorption is generally that sound absorption materials convert the energy of sound waves into mechanical energy by vibration and then into internal energy of the sound absorption materials, and the general sound absorption materials are filled in the sound absorption materials, so that the central heat cannot be transmitted in time, the internal temperature can be increased, and the sound absorption performance of the sound absorption materials is influenced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a can not form that harmful substance volatilizees, inhale the sound shock attenuation damping plate that sound material heat can in time distribute.
The technical scheme of the utility model is that:
a sound-absorbing damping plate comprises a surface layer, a butyl rubber layer, a TPE layer and a metal heat dissipation plate from top to bottom in sequence, wherein the layers are bonded by adopting polymerized rosin; the TPE in situ is provided with the intermediate layer, is provided with honeycomb heat conduction backup pad in the intermediate layer, all fill in the hole of honeycomb heat conduction backup pad and inhale the sound filler.
Furthermore, the surface layer adopts foaming resin.
Furthermore, the honeycomb heat conduction supporting plate is formed by processing a PP plate.
Further, the metal heat dissipation plate is made of an aluminum plate or a cold-rolled steel plate.
Furthermore, a fireproof paint layer is coated outside the metal heat dissipation plate.
Furthermore, the sound absorption filler adopts aerogel.
The utility model discloses an useful part lies in:
the utility model discloses a butyl rubber and TPE become etc. as main damping shock-absorbing layer, adopt the polymerization rosin bonding between each layer, do not adopt pitch as the material, stop volatilizing of harmful substance. Simultaneously set up honeycomb heat conduction backup pad between the intermediate layer on TPE layer, on the one hand for the intermediate layer provides the supporting role, and on the other hand is in order to increase the heat conductivity, and the heat that produces the acoustical absorbent at intermediate layer center passes through its transmission to TPE layer surface, then cooperates the good metal cooling panel of heat conductivity to give off, effectively avoids acoustical absorbent high temperature.

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1-2:
a sound-absorbing damping plate comprises a surface layer 1, a butyl rubber layer 2, a TPE layer 3 and a metal heat dissipation plate 6 from top to bottom in sequence, wherein the layers are bonded by adopting polymerized rosin; be provided with intermediate layer 31 in the TPE layer 3, be provided with honeycomb heat conduction backup pad 4 in the intermediate layer 31, all fill in the hole of honeycomb heat conduction backup pad 4 and inhale sound filler 5.
Specifically, the surface layer 1 is made of a foamed resin.
Specifically, the honeycomb heat-conducting support plate 4 is formed by processing a PP plate.
Specifically, the metal heat sink 6 is made of an aluminum plate or a cold-rolled steel plate.
Specifically, the metal heat dissipation plate 6 is coated with a fireproof paint layer 7.
Specifically, the sound-absorbing filler 5 is aerogel.
Polymerized rosin has a low volatility at high temperatures due to its high molecular weight, which is much lower than that of rosin. And because unsaturated double bonds in the polymerized rosin are few, the high temperature resistance and oxidation resistance of the polymerized rosin are greatly improved, the cohesive force of the polymerized rosin is higher than that of common rosin, and harmful gas similar to the traditional asphalt cannot be generated at high temperature.
TPE (thermoplastic elastomer (R1511-01)), also known as thermoplastic rubber, combines the characteristics of rubber and thermoplastics and exhibits rubber elasticity at ambient temperatures. Can plasticize the formed high polymer material at high temperature. Is the third generation rubber following natural rubber and synthetic rubber. The rubber has the excellent performances of high elasticity, aging resistance and oil resistance of the traditional cross-linked vulcanized rubber, and has the characteristics of convenient processing and wide processing mode of common plastics. The process of inhaling the sound utilizes the sound absorbing material to pass through the energy of sound wave vibration conversion to internal energy, and the sound absorbing material temperature risees at this in-process, in order to derive the heat in time, has set up honeycomb heat conduction backup pad 4 in intermediate layer 31, provides the supporting role for the intermediate layer on the one hand, and on the other hand is for increasing the heat conductivity, and the heat that produces the sound absorbing material at intermediate layer 31 center is through its transmission to TPE layer surface, then cooperates the good metal cooling plate 6 of heat conductivity to give off.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
