Description
Technical field
The invention belongs to polymer processing field, and in particular to a kind of oil resistivity road being used as under railway switch with rubber
Trouble rubber and preparation method thereof and application.
Background technology
China is carrying out large-scale Line for Passenger Transportation and high speed railway construction, will build up Line for Passenger Transportation 10,000 to the year two thousand twenty
Many kilometers, the Line for Passenger Transportation skeleton of " four vertical four is horizontal " is formed, the high-speed iron in Circum-Bohai Sea Hai Quan, the Yangtze River Delta and Pearl River Delta area is built up
More than 2000 kilometers of road.With the continuous improvement that people are required to train running speed, cause in how solving vehicle travel process
Vibrations and impact become a very crucial problem.
In order to reduce vibrations, reduce noise, novel fastener system devises resilient sleeper-bearing under iron chair, is high-speed railway
Key elastic element in fastener system, the rigidity, fatigue behaviour and combination property to whole fastener system play decisive work
With.
With rubber mat plate due to being corroded by lubricating and antirust oils and fatss for a long time under railway switch, cause its premature deformations, old
Melt split, conquassation, cause track insulation pooling feature lose, under the railway switch of part with rubber mat plate upper track using three months be
Must change.It is excessively poor with rubber mat plate oil resistivity under active service railway switch, if be continuing with, change the frequency and increase, particularly
Northwest is high and cold, high altitude localitiess change increasingly difficult, frequently changes not only constructional difficulties, also increases maintenance cost, work and bears
Load and security risk, more affect railway normal transport and safety coefficient.
At present with polychlorostyrene ester elastomer and rubber (natural rubber, butadiene-styrene rubber, ethylene propylene diene rubber) as material of main part system
The elastic insert oil absorbency used for high-speed railway made is within the scope of 8.01%～9.99%, though meet ferrum mark TB/T2626-
1995 and high ferro standard TB/T3395. (1-5) 2015 regulation oil resistivity be not more than 20% regulation, but as long as oil absorbency drop
Low one percentage point just influences whether the density degree of strand distribution, can make rubber that a range of expansion area occurs, from
And affect the physical properties index under railway switch with rubber mat plate.
Disclose using thermoplasticity polychlorostyrene ester foaming in Chinese invention patent application of the publication No. for CN102153854A
Obtained backing plate, improves hydrolytic resistance, lower temperature resistance and the resistance to ag(e)ing of backing plate, but to oil resistivity, oil absorbency, corrosion resistance
Can consider with rigidity.
The pad made with polychlorostyrene ester foaming is disclosed in Chinese invention patent application of the publication No. for CN101058629A
Plate has a low feature of low compression property, high mechanical strength and water absorption rate, but the test of fatigue behaviour 50mm × 50mm ×
Apply the vibrations of 10,000,000 (9 ± 6) KN on the test film of 10mm, do not meet " the provisional technical conditions of passenger special railway line fastener system "
The testing standard of middle fatigue behaviour, does not also consider to oil resistivity, oil absorbency, decay resistance.
Disclose in the Chinese invention patent application of publication No. CN101831118A and backing plate made using chlorinated polyethylene,
Weatherability and ageing-resistant performance are improve, but which is considered to oil resistivity, oil absorbency, decay resistance and rigidity.
Need one kind at present badly and not only conform with railroad industry standard TB/T2626-1995 high ferro standard TB/T3395. (1-5)
