Abstract
The invention discloses a sealing gasket which comprises a first outer layer, a metal layer, a middle layer and a second outer layer. The first outer layer and the second outer layer are elastic rubber cushion layers. The middle layer is a composite high-strength rubber layer or an elastic rubber layer. The elastic outer layer enables the sealing gasket to be fit better with a mechanical part. The metal layer increases mechanical properties, and more importantly protects the middle layer against corrosion and other damage to a certain extent. The service life of the sealing gasket is prolonged obviously.
Description
Technical field
The present invention relates to a kind of sealing gasket, the sealing gasket especially using in hydraulic equipment.
Background technique
Sealing gasket is very extensive in the application of engineering equipment technical field, the Main Function of sealing gasket is two sealings between mechanical part, the most rubber of existing sealing gasket is made, rigidity and corrosion resistance be non-constant all, life time is also shorter, especially for the sealing gasket of the hydraulic equipment for chemical industry, require more high.
Summary of the invention
The present invention aims to provide a kind of corrosion-resistant, and intensity is good, the sealing gasket that combination property is higher.
The present invention is achieved through the following technical solutions:
A sealing gasket, comprises the first skin, metal layer, mesosphere and the second skin successively.
Described metal layer is thin slice copper layer or thin slice stainless steel lining.
Described the first skin is elastic caoutchouc bed course with the second skin; Described mesosphere is composite high-strength rubber layer or elastic rubber layer.
Described the first skin comprises 30%-40% neoprene and nylon 10%-15% with the second outer elastic caoutchouc bed course, additive 10%, and all the other are natural rubber.
Described mesosphere includes graphite granule.
Beneficial effect of the present invention is: elastic outer layer make and mechanical part between more laminating; Metal layer has not only increased mechanical property, the more important thing is and protects to a certain extent mesosphere to avoid the destructions such as corrosion; Very significantly improved working life, industrial be a much progress.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of sealing gasket of the present invention.
Wherein 1, metal layer; 2, mesosphere; 31, the first skins; 32, the second skins.
Embodiment
First technological scheme how of the present invention is set forth by reference to the accompanying drawings.
As shown in Figure 1, sealing gasket, comprises the first skin 31, metal layer 1, mesosphere 2 and the second skin 32 successively.Described metal layer is thin slice copper layer or thin slice stainless steel lining.
Further, described the first skin is elastic caoutchouc bed course with the second skin; Described mesosphere is composite high-strength rubber layer or elastic rubber layer.
Described the first skin comprises 30%-40% neoprene and nylon 10%-15% with the second outer elastic caoutchouc bed course further, additive 10%, and all the other are natural rubber.
Further, described mesosphere includes graphite granule.
