Background technology
Amortisseur in the market, especially relates to the amortisseur on electric motor car, motorcycle, is all with spring and spring lever etc.
Composition.When or emergency case bad in road conditions so that the spring in shock mitigation system bears the pressure of increasing, easily causes spring
Damage.To this end, people install buffer rubber gasket the most in the spring, support that spring plays by yielding rubber and buffering is utilized to make
It is used for reducing the damage of spring, improves the life-span of spring.
But due to rubber compounding and production technology problem, the resistance to fracture property of existing yielding rubber is poor, holds the most very much
It is easily generated rubber crack performance, therefore, needs a kind of buffer rubber gasket with higher resistance to fracture property badly.
Additionally, the tired degradation phenomena caused by repeatedly vibrating also can reduce the damping performance of rubber blanket.Therefore, how to improve
The consistency and elasticity modulus of yielding rubber is also the problem that solution is presently required.
Filling-modified is to improve the mechanical performance of polymer and hot in polymeric material by certain or different materials being added
The cost of material or can be reduced simultaneously.For polymeric material filling-modified mainly have inorganic mineral filler and fibrous material etc..
The physical and mechanical properties that most of inorganic mineral filler can either improve material can be greatly lowered again the production cost of material；One
A little fiber-filled materials can improve mechanical performance and the hot property of polymeric matrix simultaneously.In cushioning rubber composition modal
Inorganic filler is white carbon black, but the use of white carbon black can improve the loss tangent of cushioning rubber composition.Another kind of common filler
It is vulcanizing agent, reduces the loss tangent of cushioning rubber composition by strengthening the consumption of vulcanizing agent filler, but vulcanizing agent
Increase the reduction that can bring again resistance to breaking property.Known technology also has the technical scheme using silicon dioxide to replace white carbon black, to
Yielding rubber can be made to obtain higher hardness, but due to silicon dioxide bad dispersibility in rubber, make again yielding rubber produce bullet
Property modulus reduce trend.
Along with the development of nanotechnology, application nanometer composite technology will provide new way with new for development yielding rubber modified method
Thinking.Research shows, any material enter nano-scale time all can have unusual or unusual characteristic, as surface-interface effect,
Small-size effect, quantum size effect and macro quanta tunnel effect etc..It is unusual that these characteristics make nanoparticle structural table reveal
Wuli-Shili-Renli system approach, have brilliance light, power, electricity, heat, radiate, the specific function such as absorption.
Nano inorganic powder filled polymer material can improve the performances such as the rigidity of polymeric material, hardness and wearability, and general
Logical inorganic particle filler filled polymer material all can reduce the intensity of polymeric material and tough while strengthening these performances
Property.Nano inorganic powder, owing to particle diameter is little, specific surface area big, in polymer composites, and has the strongest combination between matrix
Power, this rigidity that can not only improve material and hardness, it is also possible to play toughness reinforcing effect.Nano-particle is added to equably slow
Rush rubber can reach and improve the purpose strengthening rubber performance comprehensively.
Summary of the invention
It is an object of the invention on the basis of existing motorcycle or damping of electric vehicles device, by select the buffer rubber gasket prepared of suitable material for
The damping effect of amortisseur is improved.
Technical scheme is as follows:

Detailed description of the invention
(shock absorber structure)
A kind of shock damper, including damping cylinder 6, lead bracket 9, one end of described damping cylinder 6 is arranged on lead bracket 9 by connecting rod 7
On the other end of upper, damping cylinder 6, spring base 4 is installed, between spring base 4 and lead bracket 9, is provided with spring 5, described spring 5 and lead
Between bracket 9, junction is provided with rubber buffer 8, and rubber buffer 8 is fixed on connecting rod 7.
(cushioning rubber composition)
Table 1
| Sample | Natural rubber | Nano carbon black | Nano composite oxide | Sulfur | Mercaptobenzimidazole | Di-tert-butyl peroxide |
| 1 | 100 | 25 | 30 | 2 | 1 | 2 |
| 2 | 100 | 30 | 50 | 8 | 2 | 3 |
| 3 | 100 | 28 | 40 | 5 | 1 | 3 |
Rubber composition according to the present invention can be prepared by methods well known in the art, it may for example comprise following steps, weighs preset blending ratio
Above-mentioned material, then in rubber kneading machine, at a temperature of 100-250 DEG C, above-mentioned material is mediated 5-60 minute.
(embodiment 1-5 and reference examples 6-14)
Table 2
Use the formula shown in table 1 sample 3, by adjusting the composition of nano-oxide filler, the properties of yielding rubber is compared.
Use A type hardness tester meter to measure rubber hardness, the results are shown in Table 2.

Resistance to breaking property) × 100.
To deform the sequential determination storage elastic modulus E 1 of 1 μm → 900 μm, measure as 1 time.Calculate (E1 now(1μm)-E1(900μm))/E1(900μm).This mensuration is repeated 3 times, calculates (the E1 of the 1st time(1μm)-E1(900μm))/E1(900μm)
With (the E1 of the 3rd time(1μm)-E1(900μm))/E1(900μm)Difference.This difference is equivalent to elastic modelling quantity old oil, and this difference is little, table
Show the reduction of the elastic modelling quantity after suppression deformation load.Result is as shown in table 2.
As shown in Table 2, the nano composite oxide of employing definite composition is as inorganic filler, with the nothing individually added
Machine nano-oxide filler is compared, and has the fracture toughness of raising, and after load, the deterioration of elastic modelling quantity is inhibited, meanwhile, and tool
There is suitable hardness.
Above-described embodiment is the present invention preferably embodiment, but embodiments of the present invention being not restricted to the described embodiments,
The change made under other any spirit without departing from the present invention and principle, modify, substitute, combine, simplify, all should
For equivalence substitute mode, within being included in protection scope of the present invention.
