Abstract
The invention relates to special-purposed lubricating grease for a screw thread. The lubricating grease is characterized in that: the lubricating grease is composed of, by weight: 30% of grease, 42% of lead powder, 5% of copper oxide powder, 4% of zinc powder, 5% of an alkyl succinic acid derivative, 3% of polyisobutylene, 5% of natural graphite, and 6% of metal dialkyl dithiocarbamate. The preparing method is simple and practical. With the method, the manufactured special-purposed screw thread lubricating grease has a low cost. The lubricating grease provides a relatively high protection effect for the screw thread, and provides effects of corrosion resisting and oxidation resisting. With the lubricating grease, the service life of the screw thread is prolonged, and the quality of screw thread grease can be maintained for a long time.
Description
(1) technical field
The present invention relates to a kind of railway grease, particularly a kind of railway grease that is exclusively used in the screw thread use.
(2) background technology
Railway grease is made up of lubricating oil, performance additive and viscosifying agent, and its viscosifying agent is a kind of good distribution system of insoluble solids, and this insoluble solids can form the matrix that remains on oil semi-solid state.Because the semi-solid denseness of railway grease; They have some advantages that surpass lubricating oil, and railway grease is easy to the place that can't use because of lubricating oil because of its characterization factor, and domestic and international research is not a lot of aspect special grease now; And it is just rarer in the research of screw thread special grease; All adopt lubricating oil to replace at the very most of screw thread of China, use railway grease on a small quantity, but neither the screw thread special grease.Screw thread special grease price rare on the market is also very expensive, and result of use is also undesirable.
(3) summary of the invention
The objective of the invention is to the problem that exists in the above-mentioned technology,, providing a kind of has significantly anticorrosively, anti-oxidant to screw thread, have very strong maintainability, screw thread is had no damage, the high-quality screw thread special grease that cost is lower.
Technical scheme of the present invention:
A kind of railway grease that is exclusively used in the screw thread use, essential characteristic is: by railway grease; Lead powder; Cupric oxide powder; Zinc powder; The alkyl succinic acid verivate; Polyisobutene; Natural graphite; The dialkyldithiocarbamacompositions metal-salt is formed.The weight percent of each component is: railway grease 30%; Lead powder 42%; Cupric oxide powder 5%; Zinc powder 4%; Alkyl succinic acid verivate 5%; Polyisobutene 3%; Natural graphite 5%; Dialkyldithiocarbamacompositions metal-salt 6%.
A kind of above-mentioned railway grease that screw thread uses that is exclusively used in, essential characteristic is: railway grease is any one railway grease.
A kind of above-mentioned railway grease that screw thread uses that is exclusively used in, essential characteristic is: the granularity of cupric oxide powder is 5-10nm.
A kind of above-mentioned railway grease that screw thread uses that is exclusively used in, essential characteristic is: with railway grease; Lead powder; Cupric oxide powder; Zinc powder; The alkyl succinic acid verivate; Polyisobutene; Natural graphite; The dialkyldithiocarbamacompositions metal-salt mixes, heat and controlled temperature between 60-65 ℃, stirred 180 minutes, promptly go out this product.
Advantage of the present invention: this method of manufacture is simple and practical, and the screw thread special grease cost that makes is low, can play higher provide protection to screw thread, have corrosion-resistant, oxidation resistant effect.Prolong the practical time limit of screw thread.And can keep the quality of screw thread fat for a long time.
(4) embodiment
Embodiment
A kind of railway grease that is exclusively used in the screw thread use is by the 3# quicklime grease; Lead powder; Cupric oxide powder; Zinc powder; The alkyl succinic acid verivate; Polyisobutene; Natural graphite; The dialkyldithiocarbamacompositions metal-salt is formed.The weight percent of each component is: railway grease 30%; Lead powder 42%; Cupric oxide powder 5%; Zinc powder 4%; Alkyl succinic acid verivate 5%; Polyisobutene 3%; Natural graphite 5%; Dialkyldithiocarbamacompositions metal-salt 6%.With above-mentioned railway grease; Lead powder; Cupric oxide powder; Zinc powder; The alkyl succinic acid verivate; Polyisobutene; Natural graphite; The dialkyldithiocarbamacompositions metal-salt; Should add the weight metering by the each component weight percent, mix, heating also, controlled temperature stirred 180 minutes between 60-65 ℃.Promptly get this product.Through using these article that following advantage is arranged:
1. this product is the screw thread special grease, improves more than 1.5 times than common railway grease time limit of service.
2. this product is that screw thread special grease and congenerous special grease cost reduce about 22-26%.
3. this product is the screw thread special grease, anticorrosive than common railway grease, and resistance of oxidation increases more than 1.5 times.
Claims (4)
1. one kind is exclusively used in the railway grease that screw thread uses, and essential characteristic is: by railway grease; Lead powder; Cupric oxide powder; Zinc powder; The alkyl succinic acid verivate; Polyisobutene; Natural graphite; The dialkyldithiocarbamacompositions metal-salt is formed.The weight percent of each component is: railway grease 30%; Lead powder 42%; Cupric oxide powder 5%; Zinc powder 4%; Alkyl succinic acid verivate 5%; Polyisobutene 3%; Natural graphite 5%; Dialkyldithiocarbamacompositions metal-salt 6%.
2. according to the described a kind of railway grease that screw thread uses that is exclusively used in of claim one, essential characteristic is; Railway grease is any one railway grease.
3. according to the described a kind of railway grease that screw thread uses that is exclusively used in of claim one, essential characteristic is: the granularity of cupric oxide powder is 5-10nm.
4. according to the described a kind of railway grease that screw thread uses that is exclusively used in of claim one, essential characteristic is: with railway grease; Lead powder; Cupric oxide powder; Zinc powder; The alkyl succinic acid verivate; Polyisobutene; Natural graphite; The dialkyldithiocarbamacompositions metal-salt mixes, heat and controlled temperature in 60-65 ℃, stirred 180 minutes, promptly go out product.
