Abstract
The invention relates to a high-oil-resistance ethylene propylene diene monomer rubber composition which comprises 100 parts of unvulcanized ethylene propylene diene monomer rubber, 3-5 parts of zinc oxide, 1-3 parts of polyethyleneglycol, 1-3 parts of coumarone, 1-3 parts of stearic acid, 0.5-2.0 parts of anti-aging agent RD, 10-50 parts of carbon black N550, 100-150 parts of argil, 10-50 parts of silicon oxide, 1-5 parts of silane coupling agent, 0.5-1.5 parts of accelerator M, 1.5-2.5 parts of accelerator CZ, 0.5-1.5 parts of accelerator TMTD (tetramethyl thiuram disulfide), 0.8-2.0 parts of accelerator DTDM and 0.5-1.5 parts of vulcanizing agent. The high-oil-resistance ethylene propylene diene monomer rubber composition has excellent machine oil aging resistance, and can keep certain mechanical properties, resilience and dimensional stability under the conditions of contact with machine oil.
Description
Technical field
The present invention relates to field of rubber technology, relate to a kind of EPT rubber composition of high oil-proofness particularly.
Background technology
Along with per capita income increased in recent years, automobile comes into family gradually as the first-selected trip instrument of people, the develop rapidly of the automotive industry in recent years brought thus, the competition of automobile industry, therefore each main engine plants are more and more harsher for providing the sebific duct material therefor performance requriements of transmission medium function.
Terpolymer EP rubber because of its good high thermal resistance, ozone resistance, good processing characteristics a large amount of be used in automotive interior fluid circuit, the structure of its uniqueness can make it can use for a long time under the ozone environment of comparatively high temps, but belong to the poor-performing of resistance to machine oil of the terpolymer EP rubber of saturated nonpolar, after contact machine oil, cubical expansivity is 70% ~ 150%, hardness drops to 50% ~ 80%, tensile strength rate of descent is 60% ~ 80%, improves the new direction that the resistance to machine oil of terpolymer EP rubber also becomes terpolymer EP rubber research and development in recent years.
Summary of the invention
The object of the present invention is to provide a kind of EPT rubber composition of high oil-proofness, to improve terpolymer EP rubber injecting glue product, molded product and the resistance to aeronautic ATE of fluid circuit product.
The component of described high oil resistant terpolymer EP rubber is:
The terpolymer EP rubber of mooney viscosity 60 ~ 70, ethylene content 60% ~ 80% is selected in the present invention.
Select potter's clay and silicon oxide as main strengthening agent in the present invention, there is oleophilic group in ordinary carbon black, oil-absorption(number) is generally greater than 100ml/100g, too much interpolation can cause rubber to occur lipophilicity, machine oil is caused to contact with terpolymer EP rubber more, thus reduce terpolymer EP rubber performance, therefore select coupling agent surface modification and oil-absorption(number) be less than 30ml/100g potter's clay and surface modification after containing hydroxyl (hating oil base group) silicon oxide as strengthening agent.
Anti-aging agent RD is 2 in the present invention, 2,4-trimethylammonium-1,2-dihyaroquinoline, silane coupling agent are γ-aminopropyl triethoxysilane, captax is 2-benzothiazolyl mercaptan, accelerant CZ is N-cyclohexyl-2-benzothiazole sulfonamide, Vulcanization accelerator TMTD is tetramethyl-thiuram disulfide, vulkacit D TDM is dithiodimorpholine, and vulcanizing agent is sulphur.
The present invention, by using the rubber of the terpolymer EP rubber of high filled stone wax oil, adds the inorganic fill particle of high oil-absorption(number), increases the consumption of vulcanizing agent, makes product obtain splendid resistance to machine oil performance.Material of the present invention not only maintains the original high and low temperature resistance of terpolymer EP rubber, ozone resistance has given prominence to the key points oil resistance, can improve the resistance to aeronautic ATE of terpolymer EP rubber.
Embodiment
High oil resistant EPT rubber composition embodiment:
Select the terpolymer EP rubber of mooney viscosity 60 ~ 70 ethylene content 60% ~ 80% in the present invention, be less than the potter's clay of 30ml/100g with oil-absorption(number) and contain hydroxyl oxygen SiClx.
In mass fraction:
Make film by starting material in Example formulations and carry out testing inspection, high oil resistant terpolymer EP rubber physical performance is as follows:
Use the terpolymer EP rubber of mooney viscosity 60 ~ 70 ethylene content 60% ~ 80%.Replace part carbon black as the terpolymer EP rubber of strengthening agent using the potter's clay of surface modification and silicon oxide, resistance to aeronautic ATE condition 3# machine oil 125 DEG C × 72h, within hardness decline 15%, within tensile strength decline 25%, within volumetric expansion amount 15%, resistance to aeronautic ATE performance significantly improves, and can meet current service requirements.
