Abstract
The utility model discloses a damping silencer plate, comprising a plate body which comprises a flame retardant sponge layer, a thickened sponge layer and a noise-absorbing felt layer which are sequentially arranged from top to bottom. A rubber plastic damping plate is arranged between the flame retardant sponge layer and the thickened sponge layer. A layer of release paper with pressure sensitive adhesive is arranged on the upper surface of the flame retardant sponge layer. Through the technical solution, the flame retardant sponge layer plays a role of absorbing noise, the thickened sponge layer plays a role of buffering and damping, the noise-absorbing felt layer plays a role of duplexly absorbing noise and the rubber plastic damping plate plays a role of increasing the strength of the whole plate. After the release paper is removed, a plate with pressure sensitive adhesive can be directly adhered to the lower surface of a base plate above the space between an engine and a rear axle of a coach, so that the damping silencer plate is convenient and fast to mount. The damping silencer plate is simple in structure, easy to manufacture and is very good in silencing and damping effects, besides, the noise in the coach is fully reduced and a good travelling environment is provided for passengers.
Description
Technical field
The utility model relates to a kind of damping and silencing plate that is used on the automobile.
Background technology
For the engine of passenger vehicle to problems such as high noisy between the back axle and strong motions, present most of passenger vehicle manufacturer's employing plank external packing one deck heat insulation foam or nonwoven are set to the base plate lower surface, this damping and silencing measure is fairly simple, damping and erasure effect are all bad, greatly influence and have destroyed the good environment by bus of passenger vehicle.
The utility model content
The utility model provides a kind of damping and erasure effect splendid damping and silencing plate in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the damping and silencing plate, comprise plate body, and described plate body comprises flame-retardant sponge layer, encryption spongy layer and the sound-absorbing carpet veneer that sets gradually from top to bottom.
Be provided with the rubber and plastic damping sheet between described flame-retardant sponge layer and the encryption spongy layer.
Described flame-retardant sponge layer upper surface is provided with the release liners of one deck band pressure sensitive adhesive.
Adopt technique scheme, the flame-retardant sponge layer works to absorb noise, encrypts spongy layer and plays buffering and damping; The sound-absorbing carpet veneer plays two-sided sound-absorbing; The rubber and plastic damping sheet plays the effect that increases whole plate body intensity; Take release liners off, the plate body that has pressure sensitive adhesive directly can be adhered to the base plate lower surface of the engine of passenger vehicle to top between the back axle, quick and easy for installation.The utility model is simple in structure, be easy to make, the good damping effect of noise reduction is very good, fully reduced the noise in the passenger vehicle, for numerous passengers provide a good environment by bus.
Description of drawings
Fig. 1 is a cross section structure schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, damping and silencing plate of the present utility model comprises plate body, and plate body is made up of the flame-retardant sponge layer 1 that sets gradually from top to bottom, rubber and plastic damping sheet 2, encryption spongy layer 3 and sound-absorbing carpet veneer 4.Be provided with the release liners 5 of one deck band pressure sensitive adhesive at flame-retardant sponge layer 1 upper surface.
During use, according to actual passenger vehicle needs, a certain size plate body of cutting is taken release liners 5 off, and the plate body that will have pressure sensitive adhesive directly adheres to the base plate lower surface of the engine of passenger vehicle to top between the back axle, so just can reach the good result of damping and noise reduction.
