Abstract
The utility model relates to a heat reflection damping plywood with the functions of thermal insulation and damping, which is combined by different materials which are distributed in layers, one side surface is a heat reflection layer below which a heat insulation material layer and a damping vibration layer are arranged, and the other side surface can be covered with a pressure sensitive adhesive layer which can be covered by a piece of antisticking paper so that the utility model is convenient in operation.
Description
The utility model relates to a kind of laminate shape material, be specially adapted to improve, the equipment environmental condition on every side of vibration and noise is arranged again as existing heat radiations such as engines with heat reflection and damping vibration attenuation function.
Various hot machine kind equipments, as be widely used in engine in automobile, train, boats and ships and the engineering machinery, when work, environment distribute heat towards periphery, produce very strong vibration noise again, make its working environment on every side very abominable, and harmful health.With the automobile engine is example, and high temperature and strong vibration noise circumstance in the driver's cabin are on record.This is not still had effective measures at present solved, many employings are filled in around the hood as materials such as mineral wool, mineral wools, but its easy delamination, and have fiber to fly upward, chafe or breathing.
The purpose of this utility model is to provide a kind of heat reflection that both had for addressing the above problem, and has the laminate shape material of heat insulation vibration-damping function again.
Laminate of the present utility model is composited by the different materials of layered distribution.The outer heat-reflecting layer for the reflecting material formation in the surface of one side, as aluminium foil commonly used, the paper of aluminizing, sandwich reinforced aluminium foil etc. all can adopt.Insulation material layer should be arranged, get plate, fiberglass etc. as asbestos yarn thereafter, and the inner damping vibration attenuation layer that has micropore, the most frequently used plastic foam material can be adopted.Can adopt adhesives compound between these material layers.In use, this laminate shape material is coated on the outer cover medial surface of equipment such as engine, gearbox, makes heat-reflecting layer face heating and vibrating mass such as engine, blast pipe.Heat-reflecting layer at first can stop the heat radiation process, and insulation material layer thereafter and damping vibration attenuation layer then both can be further heat insulation, because of forming an integral body with parts such as equipment housing, changed its eigentone, so effectiveness in vibration suppression is also splendid again.
Use for convenient, the opposite side outer surface relative with heat-reflecting layer can be coated with one deck pressure sensitive adhesive adhesion coating in this laminate material, can cover one deck separate paper again outside it in case of necessity.Throwing off separate paper during use just can directly cover this laminate material at the desired area place.
Below structure of the present utility model is described, but scope of the present utility model is not limited only to this example with example shown in the drawings.
Fig. 1 structure of the present utility model
As figure, bonding is compound mutually becomes by aluminium foil layer 1, asbestos collecting plate layer 2 and polyethylene foams layer 3 successively for this routine heat reflection damping laminate.Outer surface at polyethylene foams layer 3 also is coated with one deck pressure sensitive adhesive layer 4, and is coated with one deck separate paper 5.
The test result that adopts the utility model material to carry out heat insulation experiment and sound insulation experiment sees Table 1 and table 2 respectively.Oppose than test with the rubber asbestos plate (10 millimeters thick) of present use, the temperature of engine housing cover is 36 ℃ when using this asbestos board, noise is 97.5 decibels under the engine bonnet, used the corresponding index that routine material (4 millimeters thick) records on the utility model then to be respectively 32 ℃ and 94 decibels, visible heat insulation effectiveness in vibration suppression is obvious.
Except that the veneer structure of simple flat plate type, the utility model material also can adopt mould forming method to produce the product that is fit to various special shape requirements as required.
Table 1 (test room temperature: 18 ℃)
