Abstract
The invention discloses a high temperature-resistant sealing ring. The high temperature-resistant sealing ring comprises the following raw materials in parts by weight: 9-12 parts of ethylene propylene diene monomer rubber, 6-7 parts of butadiene-styrene rubber, 2-4 parts of zinc oxide, 7-12 parts of white carbon black, 3-5 parts of a promoter, 4-6 parts of a foaming agent, 7-8 parts of naphthenic oil, 26-29 parts of titanium dioxide, 30-40 parts of natural rubber, 12-15 parts of Rhein chemie processing auxiliary, 12-13 parts of silicone rubber, 1-2 parts of silicon carbide, 1-3 parts of melamine, 13-16 parts of a vinyl fluoride, and 5-8 parts of hexafluoropropene. The high temperature-resistant sealing ring has the beneficial effects that the materials having excellent fire resistance, gas tightness and high temperature resistance such as vinyl fluoride and hexafluoropropene are added, high temperature-resistance performance is increased, and the high temperature-resistant sealing ring is not easily damaged due to high temperature.
Description
Technical field
The invention belongs to a kind of high-temperature resistant seal ring.
Background technology
It prior art is the rubber seal of a kind of axial action, as rotating shaft without means of press seals, sealing lip has preferable activeness and adaptability, can compensate for bigger tolerance and angular deviation, internal grease or fluid can be prevented to external leakage, it is possible to prevent dabbling or the intrusion of dust of the external world
, but owing to not stopping at a high speed friction between object, workpiece, after raising sealed ring deformation along with the growth temperature of fraction time, sealing can be caused to decline.So rubber seal, need to prevent high temperature wear, thus ensure good sealing effectiveness.Therefore, the resistance to elevated temperatures of rubber seal has its realistic meaning.
Summary of the invention
The deficiency existed in view of prior art, it is an object of the invention to provide a kind of novel fire resistant sealing ring.
The technical scheme realizing the object of the invention is as follows:
A kind of high-temperature resistant seal ring, it is characterised in that: it is made up of the raw material of following parts by weight: ethylene propylene diene rubber 9-12 part, butadiene-styrene rubber 6-7 part, zinc oxide 2-4
Part, white carbon 7-12 part, accelerator 3-5 part, foaming agent 4-6 part, naphthenic oil 7-8 part, titanium dioxide 26-29 part, natural rubber 30-40 part, Rhein dissipates 12-15 part, silicone rubber 12-13 part, carborundum 1-2 part, Melamine 1-3 part, vinyl fluoride 13-16 part, hexafluoropropene 5-8 part.
The present invention the invention have the benefit that the present invention possesses the anti-flammability of excellence, air-tightness, resistant to elevated temperatures material by adding vinyl fluoride and hexafluoropropene etc., can improve heat-resisting quantity, thus be difficult to high temperature failure.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, and its operation requires as follows:
A kind of high-temperature resistant seal ring, is made up of the raw material of following parts by weight: ethylene propylene diene rubber 9-12 part, butadiene-styrene rubber 6-7 part, zinc oxide 2-4 part, white carbon 7-12 part, accelerator 3-5 part, foaming agent 4-6 part, naphthenic oil 7-8
Part, titanium dioxide 26-29 part, natural rubber 30-40 part, Rhein dissipates 12-15 part, silicone rubber 12-13 part, carborundum 1-2 part, Melamine 1-3 part, vinyl fluoride 13-16 part, hexafluoropropene 5-8 part.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.Therefore, all technical staff in the art, all should be at the protection domain being defined in the patent claims the most on the basis of existing technology by logic minute analysis, reasoning or the available technical scheme of limited experiment.
