Description
Technical field
The present invention relates to automobile exhaust pipe processing technique field, be specifically related to a kind of rubber for automobile exhaust pipe
Material.
Background technology
Automobile exhaust pipe, it is installed in the exhaustor between engine exhaust branch pipe and acoustic filter, makes whole exhaust system
System is in Flexible spacecraft, thus plays vibration and noise reducing, the convenient effect installed and extend the exhausting silencer system life-span.It is mainly used in
Light-duty Vehicle, minicar and passenger vehicle, its structure is that double-ply bellows is cladded with wire sets, the structure of two ends straight section overcoat snap ring.
At present, elastomeric material has been applied in the manufacture of automobile exhaust pipe, but, owing to Tail Pipe Temperature is higher, institute
The highest requirement is had with the resistance to elevated temperatures to elastomeric material.
Summary of the invention
An object of the present invention is to provide a kind of elastomeric material for automobile exhaust pipe and preparation method thereof, can
Perfection overcomes the above-mentioned problems in the prior art.For achieving the above object, present invention employs techniques below scheme:
A kind of elastomeric material for automobile exhaust pipe, is made up of the raw material of following weight portion:
Oil extended EPDM 45 parts；
Trithiocyanuric acid 10 parts；
Bisphenol A polycarbonate 10 parts；
Polyether polyol DMN-3050 10 parts；
Light stabilizer 2 parts；
3 parts of age resistor；
Accelerator 2 parts；
1 part of paraffin；
Stearic acid 2 parts；
Vulcanizing agent 2 parts；
Martynoside. D 3 parts；
Paraffin oil 10 parts.
For the preparation method of the elastomeric material of automobile exhaust pipe, step is as follows:
1), oil extended EPDM, trithiocyanuric acid and bisphenol A polycarbonate are put in banbury, close at 90 DEG C
Refine 60 minutes；
2), in banbury, polyether polyol DMN-305010, light stabilizer, age resistor, accelerator and paraffin are added, at 90 DEG C
Lower banburying 20 minutes, after banburying terminates, controls its glue temperature binder removal below 100 DEG C, it is thus achieved that masterbatch；
3), masterbatch is put in vulcanizing equipment, adds stearic acid, vulcanizing agent, Martynoside. D and paraffin oil, successively 60 DEG C,
65 DEG C, 70 DEG C, 75 DEG C, 80 DEG C vulcanize successively 5,5,5,8,3 minutes in 5 temperature ranges, then control its glue temperature at 80 DEG C totally
Hereinafter extrude, prepare the elastomeric material for automobile exhaust pipe.
Elastomeric material for automobile exhaust pipe of the present invention and preparation method thereof, its beneficial effect shows:
1), the elastomeric material for automobile exhaust pipe of the present invention, by oil extended EPDM, trithiocyanuric acid, bisphenol-A
Type Merlon, polyether polyol DMN-305010, light stabilizer, age resistor, accelerator, paraffin, stearic acid, vulcanizing agent,
Xanthosine D and paraffin oil are made, and the elastomeric material of preparation has higher heat resistance, meanwhile, can be obviously improved exhaustor and use rubber
The service life of glue goods.
2), the preparation method of the elastomeric material for automobile exhaust pipe of the present invention, production cost is low, makes elastomeric material
Resistance to elevated temperatures be significantly improved.Meanwhile, the course of processing is relatively simple, saves the energy, meets country and subtracts about energy-conservation
The requirement of row, environmental sound, it is worth promoting.
Detailed description of the invention
Below with reference to embodiment, the present invention is described in detail.But, embodiment content is only to this
Bright example and explanation, described specific embodiment is done various repairing by affiliated those skilled in the art
Change or supplement or use similar mode to substitute, without departing from the design of invention or surmount defined in the claims
Scope, all should belong to protection scope of the present invention.
Embodiment 1
A kind of elastomeric material for automobile exhaust pipe, is made up of the raw material of following weight portion:
Oil extended EPDM 45 parts；
Trithiocyanuric acid 10 parts；

Light stabilizer 2 parts；
3 parts of age resistor；
Accelerator 2 parts；
1 part of paraffin；
Stearic acid 2 parts；
Vulcanizing agent 2 parts；
Martynoside. D 3 parts；
Paraffin oil 10 parts.
For the preparation method of the elastomeric material of automobile exhaust pipe, step is as follows:
1), oil extended EPDM, trithiocyanuric acid and bisphenol A polycarbonate are put in banbury, close at 90 DEG C
Refine 60 minutes；
2), in banbury, polyether polyol DMN-305010, light stabilizer, age resistor, accelerator and paraffin are added, at 90 DEG C
Lower banburying 20 minutes, after banburying terminates, controls its glue temperature binder removal below 100 DEG C, it is thus achieved that masterbatch；
3), masterbatch is put in vulcanizing equipment, adds stearic acid, vulcanizing agent, Martynoside. D and paraffin oil, successively 60 DEG C,
