The rubber metal composite material comprises a metal matrix, wherein bonding layers are coated on two side walls of the metal matrix, each bonding layer is bonded with a low density rubber layer obtained by adopting a rubber expansion foaming technology, and an anti-sticking layer is arranged on the outer surface of each low density rubber layer. The bonding layers are tightly bonded with the metal matrix and the rubber layers, so that the rubber layers are prevented from separating from and falling off the metal matrix; the anti-sticking layers are arranged, so that damage of the rubber layers and mutual bonding of rubber materials can be prevented, and the rubber metal composite material is applicable to volume production; the rubber metal composite material has the advantages of compressibility, oil resistance, temperature resistance, pressure resistance, compensatory property, resistance to stripping, excellent processability and low cost.
Description
Technical field
The utility model relates to a kind of rubber-metal composite.
Background technology
Common rubber-metal composite is middle be sheet metal, the direct coating rubber material in sheet metal top and bottom.The sheet material of this structure is owing to the reason of rubber property, the density of rubber layer is higher, so the whole rubber of sheet material is comparatively smooth, the sealing compensation relative mistake is a little, therefore this material relatively is applicable to the connection between the more smooth casing of flange face, and is higher to the flange face processing request.When tank surface was more coarse, the rubber layer of top and bottom can't compensate the roughness of casing, and sealing property is had a great impact, so the material of this structure generally is used for the sealing that the engine cylinder-body high surface pressure requires, instructions for use is higher.
The material that connection between common gas handling system, crankcase, the gearbox etc. is used mostly is the non-asbestos paper pad, price is medium, but because the characteristic of non-asbestos material, at the bottom of the tensile strength, the oil resistant heat resistance is relatively poor, so limited to a great extent the application of non-asbestos paper pad, very unfavorable to development from now on, therefore necessaryly develop new sealing plate material.
Summary of the invention
The utility model is not enough for prior art, and a kind of rubber-metal composite is provided, and this material has excellent compressibility, oil resistant, heatproof, withstand voltage, excellent stripper-resistance, can remedy well the roughness of flange surface.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of rubber-metal composite, comprise metallic matrix, the two side of described metallic matrix is coated with tack coat, be bonded with the low-density rubber layer that obtains by the rubber swelling foaming technique on the described tack coat, described rubber layer outer surface is provided with adherent layer.Tack coat is binding metal matrix and rubber layer closely, prevents from that rubber layer from separating with metallic matrix to come off, and is provided with adherent layer and can prevents the rubber layer damage and prevent that elastomeric material from boning mutually, is fit to the rolling batch production.
In the technique scheme, described rubber layer density is less than 1.0g/cm
3Can be easy to be extruded (good compression property), but can recover again prototype (rebound performance is good) after the extruding, the surface of rubber layer is not smooth smooth, but certain graininess roughness properties is arranged, this roughness properties can remedy the roughness of flange surface well, satisfies the requirement of sealing property.
In the technique scheme, described metallic matrix thickness is 0.1mm ~ 0.5mm.The thickness of this sheet metal can make things convenient for the production of rolling continuous batch, promotes operating efficiency.
The utility model compared with prior art, have following beneficial effect: the utility model tack coat is binding metal matrix and rubber layer closely, make not easily separated coming off of rubber layer and metallic matrix, be provided with adherent layer and can prevent the rubber layer damage and prevent that elastomeric material from boning mutually, be fit to the rolling batch production.Metallic matrix thickness is that 0.1mm ~ 0.5mm can make things convenient for the production of rolling continuous batch equally, promotes operating efficiency.By the rubber swelling foaming technique, the low-density surface rubber layer of development can better remedy the flange surface roughness.Have compressibility, oil resistant, heatproof, withstand voltage, compensatory, stripper-resistance, excellent processability, low cost and other advantages.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail: referring to Fig. 1, a kind of rubber-metal composite seal comprises metallic matrix 1, the thickness 0.1mm ~ 0.5mm of described metallic matrix 1.Described metallic matrix 1 material can be iron material matter, also can be stainless steel or other metal materials.The effect that the thickness of metallic matrix 1 is arranged to 0.1mm ~ 0.5mm is can the production of rolling continuous batch, promotes operating efficiency, and the material of metallic matrix can be iron material matter, also can be stainless steel or other metal materials.
Obtain low-density rubber layer 3 by the rubber swelling foaming technique, be coated with by quantitative glue spreading system in the two side of described metallic matrix 1 and be covered with binding agent, by the flat catalysis technique of high-temperature roller baric flow low-density elastic rubber layer 3 is sticked on this binding agent afterwards, described rubber layer density is less than 1.0g/cm
3, quality of rubber materials is selectively many, such as acrylonitrile-butadiene rubber, fluorubber, silicon rubber etc.Solidify streamline at Full-automatic high-temperature afterwards and solidify, make binding agent form the tack coat 2 of one deck densification.Like this, metallic matrix 1, tack coat 2, rubber layer 3 just closely are bonded together.
Described rubber layer 3 makes the surface produce rough graininess by the effect of catalysis, and coarse surface energy remedies the roughness of flange surface well, satisfies the requirement of sealing property.The outer surface of rubber layer 3 is provided with adherent layer 4, the adherent layer 4 that arranges can prevent rubber layer 3 damages and prevent that elastomeric material from boning mutually, so just be fit to the rolling batch production, after in addition the utility model being processed gasket seal, can prevent rubber and the bonding that box flange is installed, reusable.
The thickness of the whole sheet material of the utility model can be set according to specific circumstances, and its sheet metal thickness can be between 0.3mm ~ 1.5mm.
Metallic matrix 1 is firm with elastic rubber layer 3 bondings, the top layer has again the antiseized performance of enhancing, so that the utlity model has compressibility, oil resistant, heatproof, withstand voltage, compensatory, stripper-resistance, excellent processability, low cost and other advantages reach the sealing instructions for use.
