Abstract
The utility model discloses a foaming damping rubber piece for an automobile and relates to the technical field of automobile materials. The foaming damping rubber piece comprises an EVA foaming material layer, a self-sticking rubber damping layer and an isolation paper layer. The thickness of the EVA foaming material layer is 1.0-3.0mm, the thickness of the self-sticking rubber damping layer is 0.5-2.0mm, according to the foaming damping rubber piece, self-sticking performance is achieved, attaching force with a steel plate or a galvanized steel sheet is good, the rubber piece is non-toxic and environment-friendly, foaming can be achieved in the temperature range of 140-210 DEG C, the foaming damping rubber piece is suitable for flow line production, and vibration and noise reduction effect is good after the foaming damping rubber piece is assembled on the automobile.
Description
Technical field
The utility model relates to a kind of damp film, relates in particular to a kind of automobile foaming damp film.
Background technology
In the auto body manufacturing process, between car door, cover outside plate and reinforced rib, skeleton, there is cavity, can produces high velocity air during galloping, bring strong vibration and noise to the passenger.Therefore in light weight, adhesive ability good, the expanded material that possesses damping and acoustically effective in the application of auto trade more and more widely.Advantages such as the EVA(ethylene-vinyl acetate copolymer) material has expansion rate height, in light weight, and the vibration damping soundproof effect is good, but relatively poor with the adhesive ability of vehicle body steel plate or galvanized plate, in cavity, use easy deformation to come off for a long time.Another kind method is by buckle the EVA expanded material to be fixed in the cavity, but the method construction is easy inadequately, is unsuitable for conveyor line production.
Summary of the invention
According to above deficiency, the utility model provides a kind of automobile foaming damp film, and not only good with vehicle body steel plate or galvanized plate adhesive ability, asepsis environment-protecting is suitable for conveyor line production, has the favorable damping noise reduction simultaneously.
The technical solution adopted in the utility model is: automobile is made of EVA foamed material layer 1, self-adhering rubber damping layer 2 and separator paper layer 3 with the foaming damp film.
Wherein EVA foamed material layer 1 thickness is 1.0-3.0mm, and foaming back expansion rate is 100%-500%.；
Self-adhering rubber damping layer 2 has autohension, and thickness is 0.5-2.0mm;
The foaming damp film that adopts the utility model to obtain has autohension, good with steel plate or zincing steel sheet adhesive ability, asepsis environment-protecting, can in 140-210 ℃ of range of temperatures, foam, be suitable for conveyor line production, effect of vibration and noise reduction is good after the entrucking, and is in light weight, adhesive ability good, possess damping and acoustically effective.
Description of drawings
Further the utility model is illustrated with reference to the accompanying drawings below:
Accompanying drawing 1 is the utility model structural representation
Shown in the figure: 1--EVA foamed material layer, 2--self-adhering rubber damping layer, 3--separator paper layer
The specific embodiment
Further the utility model is illustrated according to the specific embodiment and accompanying drawing below:
Embodiment: as shown in Figure 1, automobile is made of EVA foamed material layer 1, self-adhering rubber damping layer 2 and separator paper layer 3 with the foaming damp film.
Wherein EVA expanded material layer thickness 1 is 1.0-3.0mm, and foaming back expansion rate is 100%-500%;
Self-adhering rubber damping layer 2 has autohension, and thickness is 0.5-2.0mm;
Claims (3)
1. an automobile is characterized in that being made of EVA foamed material layer (1), self-adhering rubber damping layer (2) and separator paper layer (3) with the foaming damp film.
2. a kind of automobile according to claim 1 is characterized in that with the foaming damp film described EVA foamed material layer (1) thickness is 1.0-3.0mm, and foaming back expansion rate is 100%-500%.
3. a kind of automobile according to claim 1 is characterized in that with the foaming damp film described self-adhering rubber damping layer (2) has autohension, and thickness is 0.5-2.0mm.
