Abstract
The invention relates to a hydrogenated nitrile-butadiene rubber composition. The composition comprises hydrogenated nitrile-butadiene rubber, butadiene rubber, an anti-aging agent MBZ, an anti-aging agent DDA, mixed gas carbon black, quick pressed-out carbon black N550, dioctyl adipate, dioctyl sebacate, dicumyl peroxide, triallyl isocyanurate, selenium diethyl dithiocarbamate and gamma-amino propyl triethoxysilane. The low-temperature resistance of the hydrogenated nitrile-butadiene rubber is further enhanced by using the hydrogenated nitrile-butadiene rubber and the butadiene rubber together under the combined action of auxiliary agents such as the dioctyl adipate, the dioctyl sebacate and like; the hydrogenated nitrile-butadiene rubber has the brittleness temperature of up to -56 DEG C, no breakage and still good oil resistance; and other performance of the rubber is not changed obviously. The low-temperature resistance of the hydrogenated nitrile-butadiene rubber is improved and simultaneously the use value of the rubber is improved, which has great significance for better use of the hydrogenated nitrile-butadiene and products thereof in automobile industry, petrochemical industry and the like. Moreover, the safety insurance of the products is improved and the service life of the products is prolonged.
Description
Technical field
The present invention relates to the rubber technology field, particularly the winter hardiness hydrogenated nitrile rubber composition.
Background technology
In recent years, along with the High Level of automobile with rubber item, paracril is to material transition such as acrylic elastomer and hydrogenated nitrile-butadiene rubbers.Hydrogenated nitrile-butadiene rubber is widely used in automotive industry, field of petrochemical industry with its excellent comprehensive performance.
Hydrogenated nitrile-butadiene rubber is to carry out special hydrotreatment and a kind of HI SA highly saturated elastomerics that obtains by paracril.Hydrogenated nitrile-butadiene rubber has good oil resistance; And because its HI SA highly saturated structure, it is become have good heat-resistant, one of good resistance to chemical corrosion, anti-ozone, supereminent rubber of over-all properties such as wear-resisting.At present, it is widely used in goods such as barrier film that the rolling stock brake uses, Y-shaped ring, sealing-ring as a kind of general oil-proofness rubber.This type of sealing article is the key part of whole brake, and the quality of its performance directly influences traffic safety.In the use of these oil resistant goods, because the needs of Working environment, except requiring to have the excellent oil resistance energy, also require to have extraordinary low temperature cold tolerance, temperature limit of brittleness is the most frequently used method for expressing of rubber resistance to low temperature, be meant that the disruptive top temperature appears in sample when low temperature is subjected to certain surging force, it is low more the disruptive top temperature to occur, and low temperature winter hardiness is good more.And the winter hardiness deficiency of hydrogenated nitrile-butadiene rubber, thereby influenced work-ing life of oil resistant goods.All there is the deficiency of the cold-resistant aspect of low temperature in the rubber item of standard technology production.In today of automotive industry fast development, being extensive use of of hydrogenated nitrile-butadiene rubber requires the grade of winter hardiness can be more and more higher, and insufficient winter hardiness has restrictive function for the development of the good hydrogenated nitrile-butadiene rubber of over-all properties.
Tradition hydrogenated nitrile-butadiene rubber prescription is as follows:
| Sequence number | Component | Massfraction (g) |
| 1 | Hydrogenated nitrile-butadiene rubber | 100 |
| 2 | Zinc oxide | 5 |
| 3 | Stearic acid | 0.5 |
| 4 | Sulphur | 2 |
| 5 | Antioxidant 4010 | 1 |
| 6 | Altax | 2 |
| 7 | TM monex TD | 0.4 |
| 8 | Uniflex DBS | 35 |
| 9 | High abrasion furnace black(HAF) | 80 |
Summary of the invention
Purpose of the present invention mainly is a kind of hydrogenated nitrile rubber composition of exploitation, further improve its winter hardiness, guarantee that simultaneously other performance did not have obviously to change or change to occur in the allowed band when adding some auxiliary agent improved winter hardiness, guarantee cold-resistant effect and other performance requriements of sizing material.
Hydrogenated nitrile-butadiene rubber is the interpolymer of divinyl and vinyl cyanide, the height of acrylonitrile content has bigger influence to the winter hardiness of vulcanized rubber, reach a large amount of test practices by the data of searching and determine that hydrogenated nitrile-butadiene rubber and cis-1,4-polybutadiene rubber are also with the low temperature cold tolerance that can improve sizing material.And be equivalent to reduce the acrylonitrile content of sizing material with cis-1,4-polybutadiene rubber, also reduce whole polarity of chain simultaneously, thereby reached the purpose that improves winter hardiness.Reinforcement system then adopts winter hardiness to extrude carbon black and mixed gas carbon black preferably soon.Tenderizer is to influence one of most important Synergist S-421 95 of sizing material cold tolerance, two kinds of different tenderizers are also with producing synergy, the also usefulness of hexanodioic acid dibutyl ester, sebacic acid dibutyl ester can improve the winter hardiness of sizing material greatly, also can improve the flowability and the processibility of sizing material simultaneously.
Hydrogenated nitrile rubber composition component of the present invention and ratio of quality and the number of copies are:
| Sequence number | Component | Massfraction |
| 1 | Hydrogenated nitrile-butadiene rubber | 50～90 |
| 2 | Cis-1,4-polybutadiene rubber | 10～50 |
| 3 | Antioxidant MB Z | 0.5～1 |
| 4 | Antioxidant D DA | 0.5～1.5 |
| 5 | Mixed gas carbon black | 20～40 |
| 6 | The fast carbon black N550 that extrudes | 30～60 |
| 7 | The hexanodioic acid dibutyl ester | 5～10 |
| 8 | The sebacic acid dibutyl ester | 5～10 |
| 9 | Dicumyl peroxide | 1～2 |
| 10 | Iso-cyanuric acid triallyl ester | 1～2 |
| 11 | Selenium diethyl dithiocarbamate | 1～2 |
| 12 | γ-An Jibingjisanyiyangjiguiwan | 0.5～1.5 |
By adopting hydrogenated nitrile-butadiene rubber and cis-1,4-polybutadiene rubber and usefulness and under the acting in conjunction of auxiliary agents such as hexanodioic acid dibutyl ester, sebacic acid dibutyl ester, the low temperature winter hardiness of hydrogenated nitrile-butadiene rubber has had further raising, it is still good that temperature limit of brittleness can reach-56 ℃ of non-cracking oil-proofnesss, and other performances of rubber obviously do not change yet.
The raising of hydrogenated nitrile-butadiene rubber winter hardiness has also improved the use value of rubber simultaneously, for hydrogenated nitrile-butadiene rubber material and goods thereof in automotive field, the field of petrochemical industry significance that can better play a role, the safety control and the work-ing life of having improved goods.
