Abstract
The invention discloses a kind of low pressure contracting resistance to deformation rubber seal, includes reinforced plastic layer, rubber layer from internal layer outer layers, the reinforced plastic layer, rubber layer are symmetrical and are bonded between reinforced plastic layer and rubber layer with bonding agent；The sealing ring both ends have the mounting groove group for being adapted to object installation, and the rubber layer outer surface also has surge layer.The sealing ring resistance to compression anti-deformation of the present invention is preferable, it is not necessary to worries to press long rubber layer bad the problem of, while the fiber-reinforced layer near mounting groove group plays preferably sealing humidification.
Description
Technical field
The present invention relates to seal technical field, more particularly to a kind of low pressure contracting resistance to deformation rubber seal.
Background technology
Sealing ring family, industry generally use, traditional sealing ring with nitrile rubber (NBR) for main raw material(s),
It is formulated design often can be as important considerations using tear resistance, anti-wear performance and crush resistance.But as life requires
More and more higher, single rubber seal are easy to be deformed using long, and due to elastic big easy compression, it is this
Deformation accumulation is just irreversible, has a strong impact on sealing property.
Therefore, the material to rubber seal, layer redesign is seemed extremely with strengthening its resistance to deformation and anti-compression properties
It is necessary.
The content of the invention
It is an object of the invention to provide a kind of low pressure contracting resistance to deformation rubber seal, change from incompressible, resistance to deformation angle
Enter existing rubber seal to be improved, to overcome problems of the prior art.
In order to realize the above object the technical scheme is that：
A kind of low pressure contracting resistance to deformation rubber seal, include reinforced plastic layer, rubber layer, the reinforced plastics from internal layer outer layers
Layer, rubber layer is symmetrical and is bonded between reinforced plastic layer and rubber layer with bonding agent；The sealing ring both ends have suitable
The mounting groove group of compound part installation, the rubber layer outer surface also has surge layer；The rubber layer includes following parts by weight
Component：
Isopropyl silicon rubber 50-65 parts
Neoprene 35-40 parts
Natural rubber 15-20 parts
Chlorinated polyethylene rubber 30-36 parts

Preferably, the reinforced plastic layer is polytetrafluoroethylene (PTFE) or Kynoar.Polytetrafluoroethylene (PTFE) or polyvinylidene fluoride
The resistance to compression of alkene, intensity and decay resistance are all good.
Preferably, the reinforced plastic layer is 2 ~ 3 layers of superposition.The number of plies of reinforced plastic layer ensure that internal intensity obtains
To good carrying.
Preferably, thickness of the rubber layer in both sides respectively is equal.Rubber layer thickness is equal with upper and lower uniform properties.
Preferably, the reinforced plastic layer is shorter in length than rubber layer and is placed among rubber layer, reinforced plastic layer two
Side is partially filled with fiber-reinforced layer by what rubber layer was surrounded.Gently strong layer plays sealing to fiber near mounting groove group and buffering is made
With.
The beneficial effects of the present invention are：The ring structure of the present invention is well arranged.Reinforced plastic layer has skeleton work
With rubber layer has flexible sealing effect, and the cooperation of this two kinds of layers is improved overall crushing resistance, deformation resistance；Installation
Groove group coordinates closely with object, and surge layer enhancing surface elasticity performance；Fiber-reinforced layer enhances strong near mounting groove group
Degree, buffering, sealing.The sealing ring resistance to compression anti-deformation of the present invention is preferable, it is not necessary to worries to press long rubber layer bad the problem of, together
When mounting groove group near fiber-reinforced layer play preferably sealing humidification.
