Abstract
The utility model discloses an automobile heat insulating and noise reducing device, which is characterized in that the device comprises a foam rubber material layer, a polyurethane layer bonded to the foam rubber material layer and a glass fiber aluminum foil cloth hotly pressed and compounded on the surface of the polyurethane layer. The device in the utility model which is free of toxicity, pollution and corrosion is not liable to combustion and can have heating insulating as well as noise reducing effects. The device can be applied in covering an automobile, a car engine periphery, a front wall, a floor layer and a top cover and the interlayer between two sidewalls of a train or a coach. The utility model which can prevent a heat reflection and a heat transmission can lower the temperature and reduce the noise in a cab. Meanwhile the utility model can increase the heat reflection and heat dispersion in an engine compartment and thus the fuel consumption is reduced. The utility model can further reduce automobile exhaust emission.
Description
Technical field
The utility model relates to heat insulation, the denoising device that a kind of automobile is used, and this device also can be used for locomotive.
Background technology
As everyone knows, sound absorption heat insulating material can be used as and a kind ofly suppresses flowing of heat when improving acoustics and suppressing noise, and has the material that the indoor temperature of making keeps certain effect.
Sound absorption heat insulating material mainly is used as car roof material, life material, residential housing material etc., uses the sound absorption heat insulating material of various structures according to purposes.
When using as the car roof material, be fit to adopt in foamed resin, to comprise the cushion of inorfil or tabular material, and the material etc. that polypropylene fibre and inorfil is laminated into the felt shape.
Because these sound absorption heat insulating materials not only have good hear resistance and durability, and can easily obtain raw material, therefore can reduce manufacturing cost, the problem that should solve is also arranged on the other hand.
For example, using under the situation of inorfil, when seeking the lightweight of sound absorption heat insulating material, considering the proportion of inorfil and reduce the result of fiber use amount, thereby cause material internal to form the problem that the space reduces thermal insulation.
In addition, foamed resin structurally helps improving the thermal insulation and the resistance to water of sound absorption heat insulating material, but has the problem that reduces sound absorption properties, anti-flammability on the contrary.
The utility model content
The purpose of this utility model is: at the deficiencies in the prior art, provide a kind of lower-cost automobile heat insulation denoising device.
The technical solution of the utility model is:
A kind of automobile heat insulation denoising device is characterized in that: this device comprises foam rubber-plastics material layer, and with the bonding layer of polyurethane of foam rubber-plastics material layer, also hot pressing is compounded with the layer of glass fiber aluminium foil cloth on the surface of layer of polyurethane.
Supplementary technology scheme of the present utility model is as follows:
Preferably, on fiberglass aluminum foil cloth, be evenly distributed with pore.
Preferably, on the top layer of foam rubber-plastics material layer, be coated with bonding paster.
The beneficial effects of the utility model are: this device is nontoxic, pollution-free, nothing corrosion and nonflammable, can play the effect of heat insulation noise reduction.This device can be used to cover around automobile, the motorcar engine, precedingly enclose, floor layer, top cover; Train, passenger vehicle two side intraformational bed can prevent heat reflection, and heat is transmitted, and reduce temperature and noise in the driver's cabin, and oil consumption is saved in heat reflection, heat leakage, the help that can increase simultaneously in the enging cabin.Reduce motor vehicle exhaust emission.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the schematic diagram of the utility model automobile heat insulation denoising device.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Specific embodiment of the utility model, as shown in Figure 1, a kind of automobile heat insulation denoising device, this device comprise foam rubber-plastics material layer 1, the layer of polyurethane 2 bonding with foam rubber-plastics material layer 1, also hot pressing is compounded with layer of glass fiber aluminium foil cloth 3 on the surface of layer of polyurethane 2.Change heat insulation denoising device through experimental test, when it was exposed in the flame, burning velocity satisfied the firing resistance requirement fully less than 10mm/min, and can reach relevant insulation and noise control requirement.
On the basis of the foregoing description,, can on fiberglass aluminum foil cloth, be provided with pore 4 uniformly in order to increase the anti-acoustic capability of this device.For the ease of installing, can on the top layer of foam rubber-plastics material layer, be coated with bonding paster.
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
