Abstract
The invention discloses a kind of nitrile rubber washer oil seal material, the constituent of the oil sealing material is included：80 100 parts of nitrile rubber, 20 30 parts of N550 carbon blacks, 20 30 parts of fume colloidal silica, 35 parts of molybdenum bisuphide, 35 parts of polytetrafluoroethylene powder, 5 10 parts of ethers plasticizer, 0.5 part of sulphur, 1 4.5 parts of accelerator, 1 part of stearic acid, 13 parts of paraffin；Oil sealing self-lubricating property can be significantly improved by using molybdenum bisuphide, polytetrafluoroethylene powder, it is good low, sealing property to be worn away with bearing touch, again by using fume colloidal silica, improve sizing material heat resistance, at a relatively high elasticity is maintained, washer oil seal obtained in inventive formulation can for a long time be used under environment containing soap lye.
Description
Technical field
The present invention relates to field of rubber technology, more particularly to a kind of nitrile rubber washer oil seal material.
Background technology
Nitrile rubber is that as obtained in butadiene and acrylonitrile through emulsion polymerization, nitrile rubber mainly uses low temperature emulsion
Polymerization is produced, and oil resistivity is fabulous, and wearability is higher, and preferably, bonding force is strong for heat resistance, but the oil being made using nitrile rubber
Envelope lower temperature resistance is poor, insulating properties are inferior, elasticity is slightly lower, therefore, solve the problems, such as that this class is particularly important.
The content of the invention
In view of the shortcomings of the prior art, oil sealing is improved the invention provides a kind of nitrile rubber washer oil seal material
Elasticity and heat resistance.
In order to solve the above problems, the invention provides a kind of nitrile rubber washer oil seal material, the composition of the oil sealing material
Composition is included：Nitrile rubber 80-100 parts, 20-30 parts of N550 carbon blacks, fume colloidal silica 20-30 parts, molybdenum bisuphide 3-5
Part, polytetrafluoroethylene powder 3-5 parts, 5-10 parts of ethers plasticizer, 0.5 part of sulphur, accelerator 1-4.5 parts, 1 part of stearic acid, paraffin
1-3 parts.
Further improvement is that：The constituent of the oil sealing material is included：90 parts of nitrile rubber, 25 parts of N550 carbon blacks, gas
25 parts of phase method white carbon, 4 parts of molybdenum bisuphide, 4 parts of polytetrafluoroethylene powder, 7 parts of ethers plasticizer, 0.5 part of sulphur, accelerator 3
Part, 1 part of stearic acid, 2 parts of paraffin.
Further improvement is that：The accelerator is 2- benzothiazolyl mercaptans or dibenzothiazyl disulfide.
The beneficial effects of the invention are as follows：The present invention can significantly improve oil sealing certainly using molybdenum bisuphide, polytetrafluoroethylene powder
Greasy property, it is good with the low, sealing property of bearing touch abrasion, then by using fume colloidal silica, improve sizing material heat resistance
Can, at a relatively high elasticity is maintained, washer oil seal obtained in inventive formulation can for a long time make under environment containing soap lye
With.
Specific embodiment
In order to deepen the understanding of the present invention, the present invention is further described below in conjunction with embodiment, the present embodiment
It is only used for explaining the present invention, is not intended to limit the scope of the present invention..

A kind of nitrile rubber washer oil seal material, the constituent of the oil sealing material is included：80 parts of nitrile rubber, N550 carbon blacks 20
Part, 20 parts of fume colloidal silica, 3 parts of molybdenum bisuphide, 3 parts of polytetrafluoroethylene powder, 5 parts of ethers plasticizer, 0.5 part of sulphur, promotion
1 part of agent, 1 part of stearic acid, 1 part of paraffin, add up to 143.5 parts.The accelerator is 2- benzothiazolyl mercaptans or diphenyl disulfide
And thiazole.
Embodiment three
A kind of nitrile rubber washer oil seal material, the constituent of the oil sealing material is included：90 parts of sound of chopping wood nitrile rubber, N550 carbon blacks
25 parts, 25 parts of fume colloidal silica, 4 parts of molybdenum bisuphide, 4 parts of polytetrafluoroethylene powder, 7 parts of ethers plasticizer, 0.5 part of sulphur, promote
Enter 3 parts of agent, 1 part of stearic acid, 2 parts of paraffin, add up to 161.5 parts.The accelerator is 2- benzothiazolyl mercaptans or curing two
Benzothiazole.
The present invention can significantly improve oil sealing self-lubricating property using molybdenum bisuphide, polytetrafluoroethylene powder, with bearing touch
Wear away low, sealing property good, then by using fume colloidal silica, improve sizing material heat resistance, maintain at a relatively high
Elasticity, washer oil seal obtained in inventive formulation can for a long time use under environment containing soap lye.
