Polytetrafluoroethylene (PTFE) lubricating grease filled and preparation method thereof.
[background technique]
In modern industry, the application of bearing is ubiquitous, and clearance size is the important indicator of measurement bearing accuracy, and
In this field, external product leads over always home products, and under conditions of identical clearance, domestic bearing is easier in high revolving speed
When, because stuck caused by losing oil dry grinding, domestic bearing is because the problem of material, such as steel ball, iron-clad, and wearability is lower than import production
Product, therefore the clearance of product is often all reserved very big, to overcome the problems, such as the inadequate natural endowment of material, however the clearance of big specification,
Further cause bearing guide function poor, axis beat problem is serious, seriously restricts the development of domestic bearing, also limits state
Produce the quality of Related product.
[summary of the invention]
It is a kind of applied to the low clearance bearing filling of high revolving speed the purpose of the present invention is overcoming the deficiencies of the prior art and provide
Polytetrafluoroethylene (PTFE) lubricating grease it is too small to be able to solve bearing manufacturer clearance in the case where not changing existing bearing mnanufacture process condition
Problem.
The present invention also provides a kind of polytetrafluoroethylene (PTFE) preparation of greases sides applied to the low clearance bearing filling of high revolving speed
Method.
Technical solution of the present invention is as follows:
A kind of polytetrafluoroethylene (PTFE) lubricating grease applied to the low clearance bearing filling of high revolving speed, is made of following components by weight percent:
Further, the polytetrafluoroethylene (PTFE) super fine is the particle of 5~10um.Polytetrafluoroethylene (PTFE), abbreviation PTFE,
It has excellent frictional behaviour, and friction factor is the smallest one kind in plastics, and polytetrafluoroethylene (PTFE) super fine is molecular weight 100,000
Rank, 10 microns of um of average grain diameter, polytetrafluoroethylene (PTFE) is to separate with oil in super high molecular weight, by polytetrafluoroethyl-ne
Alkene powder further crushes irradiation-induced degradation as 10um particle below, can be deposited to bearing in high speed conditions
Lasting to be lubricated cooling, polyimides to bearing among small clearance, abbreviation PI itself has good wear resistance, and
And have very strong adhesion strength, while plastic hardness can also be increased, improve the property such as anticorrosive, antifatigue, wear-resistant, impact resistance
Can, it is used in combination with PTFE and will increase bond strength, and dispersion effect of the PTFE in grease can be promoted, reach antifriction
Effect.
Further, the grease includes one or more of 15#, 32#, 68# grease mixture, the grease
Flash-point is 237~265 DEG C.
Further, the iron oxide is iron oxide red.The addition of iron oxide red can be improved Wear Resistance.
Further, the partial size of the polybenzoate is less than 2000 mesh.Polyphenyl rouge, abbreviation Ekonol, with other engineering plastics
It compares, maximum feature is that antifriction performance is good, and heatproof is higher, and has good wearability, and polybenzoate, planar structure energy is added
The coefficient of friction of system is enough reduced, and product is enable to use under high temperature environment for a long time.
A kind of polytetrafluoroethylene (PTFE) preparation of greases method applied to the low clearance bearing filling of high revolving speed, including it is as follows
Step:
(1), grease is mixed with iron oxide, polybenzoate, PI, 10~25min of time；
(2), the subtle powder of polytetrafluoroethylene (PTFE) is added in said mixture, and catalyst is added, stirred in 55~75 DEG C of conditions
5~30min is mixed, mixing speed 1~30,000 r/h obtains the polytetrafluoroethylene (PTFE) lubrication for being applied to the low clearance bearing filling of high revolving speed
Rouge.
The present invention compared with the existing technology, has the advantage that
1, a kind of polytetrafluoroethylene (PTFE) lubricating grease applied to the low clearance bearing filling of high revolving speed of the invention, utilizes poly- four
Vinyl fluoride super fine can be attached to the characteristic of other substance capillary porosities, and cooperation grease is dispersed, and can be good at gram
Take problem stuck when the small clearance of high revolving speed bearing, when polytetrafluoroethylene (PTFE) intermolecular friction, frictional resistance can be down to relatively
It is minimum；
2, a kind of polytetrafluoroethylene (PTFE) lubricating grease applied to the low clearance bearing filling of high revolving speed of the invention, in the conventional people
With Material Field, polytetrafluoroethylene (PTFE) is the smallest material of frictional resistance in all easy acquirement substances, when bearing rotation, wherein
Steel ball relatively rotate with bearing case, inner cavity, ball surfaces and bearing cavity gap location are full of polytetrafluoroethylene (PTFE) lubrication
Filling contains a large amount of polytetrafluoroethylene (PTFE) super fines at the capillary porosity of rouge, ball surfaces gap and bearing internal external chamber
Lubricating grease can greatly lower the frictional resistance between moving component, under recipe ingredient effect, polytetrafluoroethylene (PTFE) superfine
Powder is able to fully dispersed, and is uniformly mixed, and the abrasion of component can also be greatly decreased, and low noise, with small vibration, further increases
The abrasion resistance properties of bearing, when overcoming high revolving speed the problem of Bearing Temperature, are suitble to the small clearance of domestic bearing high-precision
The demand of degree；
3, a kind of polytetrafluoroethylene (PTFE) preparation of greases side applied to the low clearance bearing filling of high revolving speed of the invention
