Abstract
The invention discloses an energy-saving oil seal rubber composition, which comprises the following raw materials in part by weight: 75 to 95 parts of fluororubber, 25 to 50 parts of polyfluortetraethylene, 25 to 50 parts of filler, 0.5 to 2 parts of processing aid, 0.2 to 8 parts of colorant and 4.3 to 12.5 parts of vulcanizing agent. The product of the invention has the same process flow as that of the fluororubber, saves a surface processing process required when the polyfluortetraethylene is used and saves a spring; and at the same time, the product has high elasticity, good following performance of the fluororubber, low friction coefficient and wide high-low temperature range of the polyfluortetraethylene, so compared with the conventional product, the product has the advantages of longer service life, lower energy consumption and wider application range.
Description
Technical field
The present invention relates to a kind of rubber combination, especially relate to a kind of energy-saving oil seal rubber combination.
Background technology
Present oil sealing master lip serves as main production with two class materials, and one is a rubber elastomer, as paracril, hydrogenated nitrile-butadiene rubber, acrylic elastomer, ethylene-acrylate rubber, silicon rubber, viton etc.;
It two is used for oil sealing master lip for tetrafluoroethylene after sintering section;
This two classes material respectively has relative merits: when using rubber elastomer, good springiness, oil sealing followability are good, but the high low temperature of each material is limited in scope, and wear resistance is on the weak side; And frictional coefficient is low when using polytetrafluoroethylmaterial material, high low temperature wide ranges, but plasticity is big, a little less than the axle property, adds the adhesion problem that also will solve itself and rubber or metallic framework man-hour.So the use of above-mentioned two kinds of materials is all undesirable.
Summary of the invention
First technical problem that the present invention will solve provides a kind of energy-saving oil seal rubber combination; This rubber combination is to utilize viton and tetrafluoroethylene to belong to the fluorine material together, intermiscibility is good, get the low-friction coefficient high low temperature scope of application wide of the snappiness and the tetrafluoroethylene of viton with it, the two is together mixing, produce the oil sealing of length of holding concurrently the two by the work flow of rubber, also can save spring.
For solving the problems of the technologies described above, a kind of energy-saving oil seal rubber combination of the present invention comprises following materials based on weight:
Viton 75--95, tetrafluoroethylene 25--50, filler 25--50,
Processing aid 0.5--2, tinting material 0.2--8, vulcanizing agent 4.3--12.5;
Further, described filler is barium sulfate, Graphite Powder 99 or wollastonite powder.
Further, described processing aid is erucicamide, palm wax or low-molecular polyethylene wax.
Further, described tinting material is ferric oxide, phthalocyanine green or chrome yellow.
Further, described vulcanizing agent is extra light calcined magnesia, calcium hydroxide or dicumyl peroxide.
Sizing material physicals such as following table that above-mentioned rubber combination is prepared:
The manufacturing process of utilizing energy-saving oil seal rubber combination of the present invention to prepare energy-saving oil seal is as follows: by mill mixing rubber, mixing of rubber is by the mill heat refining, the preform machine moulding, in addition the skeleton that uses is carried out phosphatization and application of adhesive, mixing of rubber and skeleton are put into mould vulcanize, half product after the sulfuration is repaired, checks, packs, put in storage.This energy-saving oil seal product can improve flexible resistance, oil resistance, resistance to low temperature, heat aging property, the premium properties of hardness, tensile strength, tensile yield, heat-proof aging, the hydraulic efficiency oil of anti-T32, flexible resistance and the resistance to low temperature of material satisfies the product work-ing life requirement of use more than 18 months continuously simultaneously.
Product process flow after the invention process is the same with viton, reduced surface treatment process when using tetrafluoroethylene, also saved spring; Simultaneously, product has the snappiness of viton, good followability, the low-friction coefficient of tetrafluoroethylene and wide high low temperature range (through verification experimental verification, oil sealing is out of question-40～260 ℃ of uses at least) concurrently, and this makes product longer than the former life-span, energy consumption is lower, and the scope of application is wider.
