Description
Technical field
The present invention relates to field of rubber technology more particularly to a kind of sealing metal rubber and preparation method thereof.
Background technique
Rubber material is the high elastic polymer material with reversible deformation, high resilience at room temperature, in the outer of very little
Power effect is lower to generate larger deformation, remove resilient after external force.Rubber is as sealing material for the close of metal device
Feng Zhong, the noise of metal device can be effectively reduced, absorb shock and vibration etc..Rubber and metal are two different materials, it
Chemical structure and mechanical performance have very big difference, by the two effective binding energy meet people automobile, aerospace,
The demand of the various aspects such as machinery.
Hydrogenated nitrile-butadiene rubber (HNBR) is that carry out one kind obtained from special hydrotreating as nitrile rubber HI SA highly saturated
Elastomer.Hydrogenated nitrile-butadiene rubber has good oil resistance (good to fuel oil, lubricating oil, fragrant series solvent resistance)；And
And due to its HI SA highly saturated structure, its is made to have a good heat resistance, excellent resistance to chemical corrosion (to freon, acid,
Alkali has good resistance), excellent ozone resistance, higher incompressible permanent deformation performance；Hydrogenated butyronitrile simultaneously
Rubber also has high intensity, and high tear energy, the features such as wear-resisting property is excellent, are one of supereminent rubber of comprehensive performance.
Existing rubber as sealing element and when metal bonding or need to carry out by binder compactness connection or
Rubber without any caking property under the premise of be fastened in metal device and be sealed, though the former is completely embedded, after bonding just
It can not remove, inconvenience replacement and use, the latter loose or dislocation phenomenon often occur with convenience of taking, is unfavorable for sealing.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of sealing metal rubber and its preparation sides
Method, the rubber applications that this method is prepared can effectively adsorb metal in metal device, both avoid loose or dislocation
Guarantee leakproofness, and conveniently take and replace, forms class " magnet " effect with metal.
A kind of sealing metal rubber proposed by the present invention, the rubber are composed of the following raw materials by weight:
Preferably, the rubber is composed of the following raw materials by weight:
A kind of preparation method of sealing metal rubber, comprising the following steps:
(1) premix is handled: hydrogenated nitrile-butadiene rubber, white carbon black, zinc oxide and softening agent are added to mixing after mixing
It is moulded in machine and practices 5-20min, hydrogenated butyronitrile masterbatch is made；Epoxy resin, liquid polysulfide rubber and coupling agent are added to mixing
It is moulded in machine and practices 2-6min, modified refining glue is made；
(2) it is kneaded: above-mentioned hydrogenated butyronitrile masterbatch, modified refining glue, curing agent and coupling agent is kneaded 10- in mixer
20min squeezes out pelletizing；
(3) vulcanizing treatment: above-mentioned pelletizing and vulcanizing agent are placed in vulcanizing treatment 10-30min in vulcanizing agent, curing temperature is
180-190 DEG C, molding, file polishing obtains the rubber.Sulfidation at high temperature complete in the short time by short vulcanization, has
Conducive to rubber viscosity is improved, to enhance the leakproofness of rubber.
Preferably, the rubber is composed of the following raw materials by weight:
Preferably, it is 60-90 DEG C that temperature is practiced in the modeling of the hydrogenated butyronitrile masterbatch, the modified refining glue in step (1)
Modeling practice temperature be 80-100 DEG C.
Preferably, temperature is 60-70 DEG C in mixer in step (2).
Preferably, the ratio between coupling agent additive amount is 2-5:1 in coupling agent additive amount and step (2) in step (1).
Preferably, the liquid polysulfide rubber average molecular weight be 800-1000, the coupling agent be selected from KH-560 or
KH-570 organo silane coupling agent；The white carbon black is fume colloidal silica.The adhesive strength of rubber and metal is with silane coupled
The increase first increases and then decreases of agent dosage, shear strength increase with the increase of silane coupling agent dosage, and are added silane coupled
The water resistance, heat resistance of sample all will enhancing after agent；Fume colloidal silica grain diameter is smaller, is easy to be embedded in metal solid material
In the hole for expecting surface, therefore rubber and lucky suitable wetting property are preferable, enhance shear strength between the two.
In technical solution of the present invention, excellent performance is shown after epoxy resin is cured, adhesion strength is high and has resistance to
The excellent performances such as oil, acid and alkali-resistance, solvent resistant, when epobond epoxyn carries out the bonding of rubber and metal, due to asphalt mixtures modified by epoxy resin
Rouge solidify after elasticity modulus close to metal, much larger than common vulcanized rubber, to make the adhesiveness of epoxy resin and metal
Can preferably, adhesive strength sometimes even over metal material self-strength, using the preparation side in technical solution of the present invention
Epoxy resin Uniform Doped is crosslinked effect into hydrogenated butyronitrile masterbatch by method, is realized and is modified to hydrogenated butyronitrile masterbatch,
To change the elasticity modulus of hydrogenated nitrile-butadiene rubber, in the excellent properties base that hydrogenated nitrile-butadiene rubber itself is used as sealing material to have
On plinth, make it that there is certain viscosity to metal.Liquid polysulfide rubber is first kneaded with epoxy resin, the addition of liquid polysulfide rubber
Gained rubber structure can be made to form gradient distribution, avoid concentrating and cause the destruction of rigid epoxy resin due to stress, effectively keep away
Exempt from gained rubber tomography or risk of splitting, extends service life.Each group distribution ratio makes gained rubber in technical solution of the present invention
Glue to metal modest viscosity, and will not opponent or clothing etc. have caking property, be applied to metal device in, can be effectively to metal
It is adsorbed, has not only avoided loose or dislocation from guaranteeing leakproofness, but also conveniently take and replace, form class " magnet " effect with metal.
