Description
Technical field
The present invention relates to a kind of preparation method of rubber, more particularly, to a kind of preparation method of high damping cushion rubber.
Background technology
With the development of auto industry, people require more and more higher, vapour to vehicle safety, comfortableness and driver behavior
Car damping part plays vital effect to driver comfort and security.In automobile industry, common damping part
Generally rubber-metal damping part, in order to reach good shock-absorbing function, it is desirable to which these rubber-metal damping parts possess height
Damping capacity, and the damping capacity of rubber-metal damping part is mainly provided by rubber part therein, therefore it is required that setting
Rubber part in rubber-metal damping part possesses high damping properties.
The high-damping rubber for metal damping part in automobile industry typically uses butyl rubber or halogenation fourth at present
Base rubber be main base, although prepared rubber is with very high damping capacity, generally existing tensile strength it is low,
Fatigue performance difference and Nian Jie poor, the shortcomings of cure time is long, it is difficult to the need for meeting practical engineering application between metal, because
This, it is current urgent problem to develop a kind of high-damping rubber of suitable automobile shock.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of preparation method of high damping cushion rubber, pass through the preparation
The high damping cushion rubber that method is obtained has high tensile, high-adhesive-strength and fatigue proof premium properties.
The present invention solve the technical scheme that is used of above-mentioned technical problem for：
A kind of preparation method of high damping cushion rubber, comprises the following steps：
(1) on a mill add 50-55 mass parts epoxy natural rubbers, 45-50 mass parts natural rubbers, 40-
80 mass parts reinforced fillings, 10-20 mass parts softening agents, 5-10 mass parts tackifying resins, 5-10 mass parts mica sheets,
1-3 mass parts processing aids, 4-6 mass parts vulcanization of rubber activating agents, 1.5-2.5 mass parts thiofides and
1-1.5 mass parts vulcanizers, turn refining thin logical 5-7 times, blanking slice obtains glue under 45-60 DEG C of processing temperature
Material；
(2) the sizing material clot obtained above-mentioned steps (1) 5-7 times, then will be above-mentioned to exclude the bubble inside sizing material
Sizing material after clot is cut, and is put into mould, under 150-170 DEG C of curing temperature, is vulcanized 15-20 minutes,
Obtain high damping cushion rubber.
Epoxy natural rubber used is the natural rubber of epoxidation that epoxidation level is 50% in described step (1)
Glue.Epoxide group on epoxy natural rubber strand is present, and makes it have polarity, improves the glass of epoxy natural rubber
Change transition temperature, finally greatly improve the damping capacity under its normal temperature；Meanwhile, epoxy natural rubber also retains natural rubber
Basic structure and performance characteristics, can produce partially compatible and co-vulcanization, therefore selection ring with the non-polar rubber such as natural rubber
Degree of oxidation is 50% epoxy natural rubber, is ensureing that rubber has high tensile, high-adhesive-strength and fatigue proof
High damping characteristic is shown while performance.
Reinforced filling used is N330 carbon blacks and N550 carbon blacks in described step (1).N330 carbon blacks are a kind of reinforcement
Carbon black of good performance, can assign the preferable tensile property of sizing material, tear resistance, wearability；Simultaneously because its particle diameter is smaller,
Specific surface area is larger, can greatly improve the damping capacity of rubber.But N330 particle size carbon blacks are smaller, disperse poor, N330 carbon blacks
With N550 carbon blacks and with the dispersive property of carbon black can be improved using both synergies, the physics of rubber is further improved
Performance.
Softening agent used is aromatic naphtha in described step (1).Contain phenyl ring, molecule interchain in the strand of aromatic naphtha
Space steric effect can improve the damping capacity of rubber.
Tackifying resin used is P-Tert-Octyl phenol aldehyde tackifying resin in described step (1).P-Tert-Octyl phenol aldehyde
Tackifying resin is a kind of thermoplastic non-reactive, and the adhesive property and damping capacity of rubber can be improved simultaneously.
Mica sheet used is 600 mesh mica sheets in described step (1).Mica sheet to be laminar structured, rubber by
When being acted on to alternate stress, the rubbing action between mica splittings or between mica sheet and rubber molecular chain can improve rubber
Loss is acted on, and improves the damping capacity of sizing material.
Processing aid used is STRUKTOL WB212 processing aids in described step (1).STRUKTOL WB212
The scattered of the less N330 carbon blacks of particle diameter can be improved, so as to improve the tensile strength of rubber.
Activating agent used is zinc oxide in described step (1).
Thiofide used is accelerant CZ and accelerant MBT S in described step (1).
Vulcanizer used is sulphur in described step (1).In sulfur cross-linking system there is polysulfide bond in cross-bond,
The fatigue behaviour and tensile strength of rubber can be improved.
Compared with prior art, the advantage of the invention is that：
(1) this method uses epoxy natural rubber/natural rubber Blend rubber to ensure that the damping of rubber for matrix and resistance to
Fatigue behaviour：Epoxy natural rubber is a kind of natural rubber of modification, be by hydrogen peroxide or Peracetic acid with it is natural
Epoxidation reaction occurs for the double bond on rubber molecular chain, and epoxide group is introduced in its strand, therefore, the natural rubber of epoxidation
Glue has excellent damping capacity, simultaneously because stress induced crystallization phenomenon, epoxy natural rubber still has excellent thing
Manage mechanical performance and fatigue performance；
(2) this method introduces the damping capacity and adhesive strength that tackifying resin further improves rubber：Due to the glass of rubber
Glass transition temperature is generally relatively low, far below the temperature in use of automobile shock part, therefore have impact on the damping capacity of shock absorber part, and
Tackifying resin has higher glass transition temperature, and tackifying resin is introduced in rubber compounding can turn the vitrifying of rubber
Temperature is moved to high temperature direction, so as to improve the damping capacity of high-damping rubber at service temperatures.
