Abstract
The invention discloses an oil-resistant nitrile butadiene rubber seal ring. The seal ring consists of the following raw material components in parts by weight: 100 parts of nitrile butadiene rubber, 15 parts of activator FT, 5 parts of activator zinc oxide, 3 parts of plasticizer sebacic acid dibutyl phthalate, 3 parts of anti-aging agent octylated diphenylamine, 8 parts of reinforcing agent nano calcium carbonate, 10 parts of plasticizer dioctyl phthalate, 2 parts of accelerator TMTD, 2 parts of accelerator and 0.5 part of sulfur. The oil-resistant nitrile butadiene rubber seal ring has high surface polarity, good stability, low probability of swelling and good oil resistance and is particularly used for working mediums such as fuel, hydraulic oil and engine oil at 150 DEG C.
Description
Technical field
The present invention relates to a kind of sealing-ring, be specifically related to a kind of oil resistant butadiene-acrylonitrile rubber seal.
Background technology
Sealing-ring, the circular cowling being made up of one or several part, is fixed on lasso of bearing or packing ring and contacts or form narrow labyrinth clearance with another lasso or packing ring, prevents that lubricating oil from spilling and foreign object is invaded; Sealing-ring performance is with following some is relevant: as tensile strength, wear resistance, stability, tear strength, resistance toheat, erosion resistance etc.; In prior art, the above-mentioned performance of oil resistant butadiene-acrylonitrile rubber seal does not also reach good service requirements, requires further improvement.
Paracril claims again divinyl one acrylic-nitrile rubber, molecular-weight average 700,000 left and right; Canescence is to light yellow bulk or powdery solid, relative density 0.95～1.0; Acrylonitrile content is 26% paracril second-order transition temperature Tg=-52 DEG C, embrittlement temperature Tb=-47 DEG C, and the paracril second-order transition temperature Tg=-22 DEG C that acrylonitrile content is 40%; Solubility parameter δ=8.9～9.9, paracril has good oil-proofness, and its oil-proofness is only second to thiorubber and viton, and the wear resistance having and resistance to air loss.Thermotolerance is better than styrene-butadiene rubber(SBR), chloroprene rubber, can be 120 DEG C of long term operations; Resistance to air loss is only second to isoprene-isobutylene rubber; The performance of paracril is affected by acrylonitrile content, and along with acrylonitrile content increases, tensile strength, thermotolerance, oil-proofness, resistance to air loss, hardness improve, but elasticity, winter hardiness reduce; Water tolerance is better.
Summary of the invention
For addressing the above problem, the object of the invention is to provide that a kind of sealing-ring surface polarity is large, good stability and be difficult for swelling oil resistant butadiene-acrylonitrile rubber seal.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of oil resistant butadiene-acrylonitrile rubber seal, it is made up of following material composition and weight part: 100 parts of paracrils; 15 parts of activator FT; 5 parts, promoting agent zinc oxide; 3 parts of softening agent sebacic acid dibutylesters; 3 parts of protective agent octylated diphenylamines; 8 parts of strengthening agent nano-calcium carbonates; 10 parts of fluidizer dioctyl phthalate (DOP)s; 2 parts of Vulcanization accelerator TMTDs; 2 parts of accelerant CZs; 0.5 part, sulphur.
Beneficial effect:
Compared with prior art, oil resistant butadiene-acrylonitrile rubber seal of the present invention is using butyronitrile rubber as main raw material(s), and paracril has the following advantages, and tensile strength, thermotolerance, oil-proofness, resistance to air loss and hardness are all higher, and water tolerance is better; By proportionally add above-mentioned other starting material in butyronitrile rubber, the sealing-ring surface polarity of producing is large, and good stability is difficult for swellingly, and oil-proofness is good, is used in especially the working mediums such as the fuel oil of temperature at 150 DEG C, hydraulic efficiency oil, machine oil.
Embodiment
The present invention will be further described below:
Oil resistant butadiene-acrylonitrile rubber seal of the present invention, it is made up of following material composition and weight part: 100 parts of paracrils; 15 parts of activator FT; 5 parts, promoting agent zinc oxide; 3 parts of softening agent sebacic acid dibutylesters; 3 parts of protective agent octylated diphenylamines; 8 parts of strengthening agent nano-calcium carbonates; 10 parts of fluidizer dioctyl phthalate (DOP)s; 2 parts of Vulcanization accelerator TMTDs; 2 parts of accelerant CZs; 0.5 part, sulphur.
By proportionally add above-mentioned other starting material in butyronitrile rubber, the sealing-ring surface polarity of producing is large, and good stability is difficult for swellingly, and oil-proofness is good, is used in especially the working mediums such as the fuel oil of temperature at 150 DEG C, hydraulic efficiency oil, machine oil.
Embodiment recited above is described the preferred embodiment of the present invention, not the spirit and scope of the present invention is limited.Do not departing under the prerequisite of design concept of the present invention; various modification and improvement that this area ordinary person makes technical scheme of the present invention; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, has all been documented in claims.
