Description
Technical field
The invention belongs to rubber seal processing and manufacturing technology, and in particular to a kind of motorcycle cold resistant rubber is close
Sealing.
Background technology
Rubber seal is that a kind of general basic element rubber seal in sealing device extensively should in Sealing Technology
A kind of rubber.Because its flexible modulus is small, elongation is high, is widely used in pacifying the advantages of resistance to gas permeability
In various plant equipment.Need also exist for using rubber seal, the quality of rubber seal in motorcycle brake pincers part
The safety and stability of motorcycle brake system is seriously affected, when motorcycle is run at low ambient temperatures, rubber seal
Part deforms to the cold, and mechanical characteristic declines, and causes it using the fluctuation of quality or even fails.Existing most of rubber seals are resistance to
Low-temperature characteristics is not satisfactory.
The content of the invention
The purpose of the present invention is to be directed to the problem of existing, there is provided a kind of motorcycle cold resistant rubber seal.
The present invention is achieved by the following technical solutions：
A kind of motorcycle cold resistant rubber seal, by the material composition of following parts by weight：

Part glass fibre, 1 ~ 3 part of dispersant, 5 ~ 7 parts of vulcanizing agents.
Preferably, by the material composition of following parts by weight：
85 parts of nitrile rubbers, 18 parts of silica flours, 13 parts of nano titanium oxides, 33 parts attapulgite modified, 10 parts of glass fibres, 2 parts
Dispersant, 6 parts of vulcanizing agents.
Further, the granular size of described silica flour is 300 ~ 350 mesh.
Further, the granular size of described nano titanium oxide is 30 ~ 80nm.
Further, described attapulgite modified preparation method comprises the following steps：
（1）Attapulgite is put into temperature as 50 ~ 60min of calcination processing under conditions of 800 ~ 850 DEG C, after the completion of take out standby
With；
（2）By step（1）Attapulgite after processing is put into modified solution and filtered out after 40 ~ 50min of immersion treatment, during which adds
It is 70 ~ 75 DEG C that heat, which keeps the temperature of modified solution, while enters the ultrasonication that line frequency is 80 ~ 85kHz, and finally it is dried
Handle to constant weight；Each composition and its corresponding parts by weight are in the modified solution：10 ~ 15 parts of iron powders, 5 ~ 8 parts of octadecyls

Potassium, 180 ~ 200 parts of water.
Further, step（2）Described in drying process temperature be 85 ~ 90 DEG C.
Further, step（2）Described in the granular size of iron powder be 20 ~ 50nm.
Attapulgite has been one of filler common in rubber parts processing and manufacturing, and it can effectively improve the power of rubber parts
Characteristic, abrasion-proof corrosion-proof etc. are learned, but is contributed less for the resistance to low temperature of rubber parts, while attapulgite at low temperatures
Interface unbound occurs between particle shrinkage, with the rubber matrix tissue of surrounding, have impact on the mechanical characteristic of rubber parts and resistance to low on the contrary
Warm nature energy, the present invention have carried out targetedly improvement processing to this problem, wherein first having carried out calcination processing to attapulgite, carried
Its surface-active is risen, its loose institutional framework, has added the spacing of lamella inside its particle, established for follow-up processing
Basis, processing is then modified to it with modified solution, by the iron powder intercalation of nano particle size inside attapulgite particle, profit
With the characteristic of the special pyrocondensation cold expanding having of iron powder, the shrinkage effect of attapulgite under low temperature condition can be effectively offset, is lifted
The volume and stability of attapulgite filler particles, so as to improving the low temperature resistant of rubber seal, mechanical characteristic etc..
The present invention has advantages below compared with prior art：
The present invention has carried out special optimization collocation to the constituent of rubber seal and handled, final obtained rubber seal
With good low temperature resistant and mechanical characteristic, the safety in utilization of motorcycle brake pincers part is improved, has and promotes well
Use value.
