Abstract
The invention relates to an extreme pressure additive for industrial lubricating grease. The additive is basically characterized in that the additive comprises the following components, by weight, 29-31% of molybdenum disulfide, 19-23% of chlorinated paraffin, 2-6% of diarylamine, 2-6% of an ethoxy phenol, 2-6% of bis-salicylidene propanediamine, 4-8% of a dialkyldithiophosphate, 3-7% of polyisobutylene, 2-3% of polyethylene, and the balance base oil. The additive has the advantages of simple preparation, convenience and easy implementation, and economy and utility, and can maintain the good denseness of the lubricating grease. The additive which ensures the extreme pressure resistance stability of a gear, a bearing and a mechanical part which have heavy load or suffer from shock load allows devices using the lubricating grease to be comprehensively maintained; and the additive which ensures the improvement of extreme pressure resistances of various mechanical devices allows various performances of the lubricating grease to be comprehensively upgraded, so the use period of the lubricating grease is prolonged.
Description
(1) technical field
The present invention relates to a kind of grease additive, particularly a kind of preparation scheme and method of manufacture of industrial grease extreme-pressure additive.
(2) background technology:
Because the semi-solid state of railway grease makes railway grease be sealed in the bearing more easily, and railway grease moist can also serve as down to seal with the environment that dust is arranged resist pollution.Therefore the user demand of railway grease is very big, along with the progress of society and human sciences's development, makes all kinds of mechanical means in continuous development, so require to improve the serviceability of each series lubricant agent.Railway grease more should improve all kinds of performances because of the factor of its work characteristics.In the application of meeting generation shock load; As in the bearing and some travelling belt bearing of large-scale navvy; The quick loading meeting of load generates the scratch that expendable film caused metal in the past in the reaction of dissolved extreme-pressure additive, so extreme pressure lubricant generally is can form film in the metallic surface to alleviate sliding friction.But effect does not highlight.And more can not in anti-extreme pressure, promote the over-all properties of railway grease comprehensively.Therefore do not reach comprehensive maintenance to all kinds of mechanical means.The price of existing railway grease extreme-pressure additive is also higher.
(3) summary of the invention
The objective of the invention is to the problem that exists in the above-mentioned technology; Provide a kind of high-quality; Low price is guaranteed at heavy lift and is subjected to form protective membrane on gear, bearing and the mechanical means parts of shock load, needs to use the mechanical means of railway grease can play comprehensive maintenance to all kinds of; And guarantee when promoting anti-extreme pressure, to promote the railway grease extreme-pressure additive of railway grease over-all properties comprehensively.
Technical scheme of the present invention:
A kind of industrial grease extreme-pressure additive, essential characteristic is: by base oil; Molybdenumdisulphide; Clorafin; Diaryl-amine; The oxyethyl group phenols; Two salicylidene tn; Dialkyl dithiophosphate; Polyisobutene; Vilaterm is formed.The weight percent of each component is: molybdenumdisulphide 29-31%; Clorafin 19-23%; Diaryl-amine 2-6%; Oxyethyl group phenols 2-6%; Two salicylidene tn 2-6%; Dialkyl dithiophosphate 4-8%; Polyisobutene 3-7%; Vilaterm 2-3%.Surplus is a base oil.
A kind of above-mentioned industrial grease extreme-pressure additive; Essential characteristic is: base oil is a mineral base oil: 5 centistokes, 10 centistokes, 500SN; M14; The combination of wherein any one component in the VT 18 of 32#, 68# any two kinds of components and vegetables oil wherein, rapeseed oil, Oleum Gossypii semen, the Viscotrol C, the weight quota of three kinds of components is: 1: 1: 1.Or by 5 centistokes of MO, 10 centistokes, 500SN, M14,32#, any one component combination in any one component among the 68# and the VT 18 of vegetables oil, rapeseed oil, Oleum Gossypii semen, the Viscotrol C, the weight quota of two components is 2: 1 or 1: 1.
A kind of method of manufacture of above-mentioned industrial grease extreme-pressure additive, essential characteristic is: with base oil; Molybdenumdisulphide; Clorafin; Diaryl-amine; The oxyethyl group phenols; Two salicylidene tn; Dialkyl dithiophosphate; Polyisobutene; Vilaterm mixes, and heating also, controlled temperature stirred 120-240 minute between 60-80 ℃.Promptly get product.
Advantage of the present invention: the present invention prepares simply, and is convenient and easy, economical and practical.Can keep good grease consistency for a long time.And guarantee heavy lift with and be subjected to the equipment that the anti-extreme pressure of gear, bearing and the mechanical part of shock load can stabilize and increase all kinds of use railway grease and play comprehensive maintenance.When guaranteeing, promote all kinds of performances of railway grease to all kinds of mechanical means raising anti-extreme pressures abilities comprehensively.Prolong the life cycle of railway grease.
