Abstract
The invention discloses a sealing gasket for an oil tank. The sealing gasket for the oil tank comprises, by weight, 42-46 parts of precipitated white carbon black, 2.5 parts of 2, 2'-disulfbenzothiazole, 70-75 parts of chemigum, 1-1.5 parts of tetra methylthiuram disulphide, 19-28 parts of dibutyl phthalate, 28-34 parts of polyvinyl chloride, 4-5 parts of zinc oxide, 2 parts of stearic acid, 1.5 parts of sulphur, 2-3 parts of N-isopropyl-N'-phenyl p-phenylenediamine, 2 parts of anti-aging agent RD and 2-3 parts of diethylene glycol. The sealing gasket for the fuel tank can effectively overcome the short service life caused by the poor oil-resistant performance and ensures the overall using performance of the sealing gasket.
Description
Technical field
The present invention relates to auto parts machinery field, be specifically related to a kind of fuel tank gasket.
Background technology
The selection of gasket material to its sealing property and work-ing life important in inhibiting.The performance of material directly affects the use properties of gasket.Automotive oil tank gasket in use will contact with oils, and at this moment oils can penetrate into gasket inside to make it produce swelling, causes the intensity of gasket and other mechanical properties to reduce.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of fuel tank gasket, sealing spacer has high-strength oil resistance, ensures the use properties of gasket entirety.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of fuel tank gasket, comprises each component by following parts by weight proportioning:
Precipitated silica: 42-46 part
2,2'-dithio-bis-benzothiazole: 2.5 parts
Paracril: 70-75 part
Tetramethyl thiuram disulfide: 1-1.5 part
Dibutyl phthalate: 19-28 part
Polyvinyl chloride: 28-34 part
Zinc oxide: 4-5 part
Stearic acid: 2 parts
Sulphur: 1.5 parts
N-sec.-propyl-N '-diphenyl-para-phenylene diamine: 2-3 part
Anti-aging agent RD: 2 parts
Glycol ether: 2-3 part.
Further, by each component by mixing after corresponding parts by weight proportioning, the rubber unvulcanizate after mixing is carried out extrusion molding, sulfuration is carried out to the goods after extruding and obtains gasket finished product.
A kind of fuel tank gasket of the present invention, comprise paracril, polyvinyl chloride, zinc oxide, stearic acid, sulphur, precipitated silica, 2,2'-dithio-bis-benzothiazole, tetramethyl thiuram disulfide, dibutyl phthalate, N-sec.-propyl-N '-diphenyl-para-phenylene diamine, anti-aging agent RD, glycol ether, and be provided with respective weight fraction proportioning, thus short defect in work-ing life that the difference of oil resistance in prior art causes can be overcome, ensure the use properties of gasket entirety.
Embodiment
A kind of fuel tank gasket described in the embodiment of the present invention, comprises each component by following parts by weight proportioning:

Tetramethyl thiuram disulfide: 1-1.5 part
Dibutyl phthalate: 19-28 part
Polyvinyl chloride: 28-34 part
Zinc oxide: 4-5 part
Stearic acid: 2 parts
Sulphur: 1.5 parts
N-sec.-propyl-N '-diphenyl-para-phenylene diamine: 2-3 part
Anti-aging agent RD: 2 parts
Glycol ether: 2-3 part.
Further, by each component by mixing after corresponding parts by weight proportioning, the rubber unvulcanizate after mixing is carried out extrusion molding, sulfuration is carried out to the goods after extruding and obtains gasket finished product.
A kind of fuel tank gasket of the present invention, comprise paracril, polyvinyl chloride, zinc oxide, stearic acid, sulphur, precipitated silica, 2,2'-dithio-bis-benzothiazole, tetramethyl thiuram disulfide, dibutyl phthalate, N-sec.-propyl-N '-diphenyl-para-phenylene diamine, anti-aging agent RD, glycol ether, and be provided with respective weight fraction proportioning, thus short defect in work-ing life that the difference of oil resistance in prior art causes can be overcome, ensure the use properties of gasket entirety.
Last it is noted that the foregoing is only the preferred embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; it still can regulate the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
