Description
Technical field
The invention belongs to field of rubber materials, more particularly to a kind of oil resistant low temperature resistant rubber and preparation method thereof.
Technical background
With extensive use of the rubber material in the heavy industry and new industry such as digging, traffic, building, machinery, electronics,
To the performance of rubber material, more stringent requirements are proposed, especially the oil resistant low temperature resistant performance of rubber, and low temperature resistant and oil resistivity
It can be a pair of contradictory body, according to similar compatibility principle, rubber molecule polarity is stronger, and small molecule oil product is poorer to its permeability,
Oil resistivity is better, and molecular polarity more force it is intermolecular interaction it is bigger, to the binding force of the movement of strand and segment
Also bigger, so that glass transition temperature Tg increases, to make rubber keep elastic reduced capability under certain low temperature, i.e.,
Resistance to low temperature is deteriorated.Therefore single rubber base material is no longer satisfied use demand.
The performance of rubber product also has close ties, rubber in addition to related with the property of rubber matrix itself with balanced constant
The locomitivity that the cold resistance of glue is mainly reflected in strand is stronger, and intermolecular movement is relatively easy, the energy of molecule cohesion
Opposite is low.Presently most used solution first is that the selection and use of plasticizer, plasticizer can be such that rubber molecule moves
It becomes easy, reduces the active force between rubber molecule, to reduce the glass transition temperature of rubber, improve rubber plasticity and flowing
Property, convenient for calendering, the forming operations such as extrude, while certain physical mechanical properties of vulcanizate can also be improved, such as reduce hardness and
Stress at definite elongation assigns higher elasticity and lower heat, raising cold resistance etc..
Summary of the invention
The purpose of the present invention is to provide a kind of oil resistant and resistance to low temperature balance are preferable, while having both good physical machine
Tool performance, production method is simple, oil resistant low temperature resistant rubber easy to industrialized production, to meet the use need of people's production and living
It asks.
To achieve this purpose, the present invention adopts the following technical scheme:
A kind of oil resistant low temperature resistant rubber of the present invention, the raw material composition of following components by weight percent: 50-80 parts of natural rubber, butyronitrile
20-50 parts of rubber, 40-80 parts of carbon black, 5-20 parts of plasticizer, 2-20 parts of zinc oxide, 1-5 parts of stearic acid, 1-10 parts of anti-aging agent, sulphur
1-8 parts of sulphur, 1-8 parts of vulcanization accelerator, L-181-4 parts of processing aid.
The natural rubber is any one of pimpled rubber, smoke sheet rubber, air dried sheet glue, crepe rubber.
The nitrile rubber is nitrile rubber 1052, and wherein acrylonitrile content is 31%-35%.
The carbon black is high abrasion furnace carbon black N330, general purpose furnace black N660, spray carbon black, one in semi-reinforcing carbon black N774
Kind or several combinations.
The plasticizer is one of polyethers plasticizer TP-90B and Etheric ester type plasticizer TP-95.
The anti-aging agent is the two kinds of arbitrary proportion mixing of anti-aging agent RD and antioxidant BLE.
The vulcanization accelerator is one of sulfenamide accelerator CZ and accelerator D TDM or two
Kind combination.
A kind of preparation method of oil resistant low temperature resistant rubber, including following operating procedure:
(1) take natural rubber on a mill it is thin it is logical beat after triangle bag plasticates 5 times, add nitrile rubber together it is thin lead to beat
Triangle bag is plasticated 20 times, and temperature is controlled at≤60 DEG C, after plasticating, broken-down rubber is obtained after bin aging 8h, and can detecte door
Buddhist nun's viscosity examines Mooney viscosity result to be no more than 40, and relatively low Mooney viscosity is conducive to improve the dispersibility of sizing material.
(2) broken-down rubber and carbon black, zinc oxide, stearic acid, plasticizer, processing aid step (1) plasticated are thrown in succession
Enter in the banburying chamber of mixer, mixing room temperature is no more than 50 DEG C when throwing glue, and mixing time 12-18min, mixing room temperature reaches
To 100 DEG C of dumping blowings, 8 hours are parked for use.
(3) sizing material and anti-aging agent, sulphur, vulcanization accelerator that are kneaded in step (2) are put into mixer be kneaded together
6-10min, mixing room temperature is no more than 35 DEG C when throwing glue, and mixing room temperature reaches 70 DEG C of dumping blowings, after parking 8 hours to obtain the final product
Oil resistant low temperature resistant rubber.
Beneficial effects of the present invention: rubbery system of the present invention is used in combination using natural rubber with nitrile rubber, and natural rubber is
Most widely used general purpose rubber, because of its elasticity with higher, slightly band plasticity, cold resistance has extraordinary machinery after reinforcement
Intensity, but natural rubber main chain contains double bond, is easy under attack, not ageing-resistant, oil resistivity, chemicals-resistant (in addition to alkali) performance
It is bad, therefore application is restricted.Nitrile rubber is a kind of synthetic rubber as prepared by butadiene and acrylonitrile compolymer, is
Oil resistant (especially alkane oil), the preferable synthetic rubber of ageing-resistant performance, mainly for the manufacture of oil resistant rubber product, acrylonitrile contains
Amount is more, and oil resistivity is better, but cold resistance then accordingly declines.The two is used in combination, the oil resistant that can not only improve rubbery system is resistance to
Low temperature properties can also be effectively improved processing performance.
Rubbery system of the invention is used in the excellent natural rubber of resistance to low temperature and the excellent butyronitrile rubber of oil resistance
Glue 1052 simultaneously uses and uses TP-90B or TP-95 as rubber plastizing agent, compared with common natural rubber, rubber of the invention
Glue is with oil resistant, resistance to low temperature, and suitable for the use of the continuous duration under cryogenic conditions, and rubber preparation method is simple
Single, at low cost, sizing material processing performance is good, easy to industrialized production.
