Description
Technical field
The present invention relates to rubber parts production field, be specifically related to a kind of wide temperature range high-velocity fluid power oil sealing, and the manufacture method of this oil sealing.
Background technology
Polymer seal, as a vitals of mechanical basic part, is the important guarantee of all kinds of mechanical host performance, quality, security, reliability etc.No matter be the major areas such as the industry such as traffic (automobile, train), engineering machinery, mining machinery, environmental protection machinery, or Aeronautics and Astronautics, all be unable to do without rubber seal, and there is irreplaceability.
Oil sealing, due to working conditions harshness, determines elastomeric material requirement harsh.The oil sealing material of current use, except common occasion adopts paracril, the special materials such as fluoropolymer, acrylate copolymer, silicon polymer, silicon-fluorine polymer thing, Hydrogenated nitrile, tetrafluoroethylene are widely adopted.
Traditional polymeric resilient seal material butyronitrile polymkeric substance (NBR), acrylic ester polymer (ACM), fluoropolymer (FPM), due to the linear velocity that it bears, cannot meet high temperature, at a high speed, the actual applying working condition of high abrasion, thus higher technical requirements is proposed to sealing base mateiral.The approach solving material technology performance reduces frictional coefficient and friction Temperature Rise, improves use linear velocity and the heat resistance of material, material is had physical and chemical performances such as wear-resisting, high temperature resistant, resistance to height is oily, ageing-resistant.
Summary of the invention
For above problems of the prior art, the invention provides a kind of wide temperature range high-velocity fluid power oil sealing.
The present invention is achieved by the following technical solutions:
A kind of wide temperature range high-velocity fluid power oil sealing, described feed composition and weight part as follows:
Oil sealing base material 100
Fortifying fibre 5 ~ 35
Nano filling 3 ~ 20
Wherein, described oil sealing base material is the mixture of Hydrogenated nitrile, tetrafluoroethylene, styrene based copolymer, or oil sealing base material is the mixture of Hydrogenated nitrile and styrene based copolymer, and relative proportion is any; Or oil sealing base material is styrene based copolymer, or oil sealing base material is Hydrogenated nitrile; Described styrene based copolymer is styrene-ethylene/propylene-styrene copolymer; Described Nano filling is one or several in nano composite material of anionic polymerization nylon, nano layered silicate, nano-calcium carbonate, nano-aluminium oxide, and comparative example is any; Described oil sealing is interpenetrating polymer networks structure.
Described fortifying fibre comprises inorganic fibre and/or organic fibre, and relative proportion is any.
Described inorganic fibre is carbon fiber.
Described organic fibre is aramid fiber.
Beneficial effect of the present invention is: based on oil sealing base material, be aided with that fortifying fibre and Nano filling make, there is the wide temperature range high-velocity fluid power oil sealing of interpenetrating polymer networks structure, due to the fluoropolymer adopting common substrate to replace price high, and the acrylate adhesive of process tolerance difference, significantly reduce production cost; Under the prerequisite of simplifying raw material, by preparing burden, plasticating, mixing, sulfuration, the operation such as post-treatment complete the manufacture of oil sealing, simplifies the technological process of production, improve production efficiency; The oil sealing made has suitable oily swelling property, sealing effectiveness is good, the inierpeneirating network structure (IPN) formed, improve finished product to high rotating speed, high/low temperature, the adaptability of oil resistant operating mode and the reliability of use, its temperature resistant grade is at one 35 DEG C ~+200 DEG C, and transient temperature can reach 300 DEG C; Sealing fluid line speed reaches 20 meter per seconds, and therefore oil seal product of the present invention has satisfactory prod advantage and cost performance.
Embodiment
Above raw material all can from market purchasing.
Wherein: oil sealing base material, as the basic raw material that oil sealing manufactures, its selection must consider that the consistency of material to working medium, the adaptability to operating temperature range and antelabium are to follow-up capability during turning axle high speed rotating.What the present invention adopted is one or several in Hydrogenated nitrile, tetrafluoroethylene, styrene based copolymer, and relative proportion is any.Wherein styrene based copolymer select to as if styrene-ethylene/propylene-styrene copolymer.
Fortifying fibre, refer to resin (polymkeric substance) compound after can improve polymkeric substance mechanical strength and product size stability, reduce shrinking percentage or reduce the fibrous material of thermal distortion.In the present invention, suggestion adopts inorganic fibre and/or organic fibre, as carbon fiber, aramid fiber.
Application target in Nano filling the present invention, is special purpose for realizing rubber or function and provide toughened and reinforced or propose high performance effect.Wherein, nano composite material of anionic polymerization nylon, for China's granted patent protection product, (patent No. is: 02138152.6).
The method that the composition of raw materials provided according to above-described embodiment carries out oil sealing manufacture is:
1, prepare burden: by the recipe requirements precise in each embodiment.
2, plasticate: adopt plasticator, by broken glue, one section plasticate, park cooling, close refining, two sections plasticate, three sections plasticate, the sampling of bag roller, divide the operation such as car stacking to complete operation of plasticating;
3, mixing: to adopt mixing roll, by bag roller, mixing, beat the operations such as triangle bag, horizontal look, slice sampling, film cooling and complete mixing operation;
4, sulfuration: adopt vulcanizer, by die cavity being put skeleton, pressure is opened in filler, start, suppress the operation such as exhaust, sulfuration depanning completes curing operation;
