; Patented Jan'- 3, 1933 UNITED STATES PATENT OFFICE SHINTA EATSUNAWA, OI IOGI KACHI, TOYOTAMA GUN, AND FUSATOSHI NOZAWA, OF
' EIGASHI GHOFU MAORI, EBABA GUN, TOKYO F'U, JAPAN LUIBBIQAHT AND METHOD OF PREPARING- SAME worming. Application m September 21, 1981, Serial no. 564,248, and in J'apan October 4, 1930.
This invention relates to a method of preparing a lubricant, which consists in adding to lubricating mineral oil a proper quantity of petrolene. The petrolene is obtained by dissolving a bituminous substance in a solvent such as naphtha (benzine) or carbon tetrachloride and driving out the said solvent.
The object of this invention is to obtain a good lubricant at a small cost.
Ouiinvention is based upon a newly-discovered fact assummarized below When 'petrolene as popularly known, is added to lubricatin mineral oil, the surface tension of the oil is remarkably decreased,
, the film of oil can be kept unbroken for a long time and furthermore emulsification can easily be eifected.
A clear idea may be had of the invention by referring to the following instances ascertained as a result of many years of research and experimentation When lubricating mineral oil is mixed with 0.2% to 8% by weight of petrolene, its lubricating property is greatly improved. Therefore, it goes without saying that lubricating mineral oil itself to which nothing but petrolene is added can be advantageously used as alubricant.
'Further, the solution of 0.2% to 8% by weight of petrolene in lubricating mineral oil can easily be emulsified by gradually adding toit a quantity of lime water, say, 1% to 60% in volume of the total and by stirring the mixture. y
The emulsified lubricant thus obtained is in a state like water in oil, and,,being very stable, can be kept long in an emulsified state.
I The film of the oil is strong and very suitable for lubricating and cooling those parts of mec anism subjected to friction. The emulsified lubricant itself can be used as a substitute for mineral oil.
As to the theory of the emulsifing process, it is believed that petrolene acts as an adsorptive in lubricating mineral oil, and the emulsificat-ion with lime water is facilitated by a great decrease in the surface tension of the lubricating mineral oil, while the lime water is being added and the mixture stirred.
ployed as the constituent lubricating mineral oil when a lubricant of higher viscosity is necessary. In this. case, better results are obtained by the following process than with the solution obtained by directly adding petrolene to cylinder oil. I
Petrolene ranging from 10% to 40% of the total weight is dissolved in 90 to of mineral oil of low viscosity such as machine oil (this solution we call auxiliary emulsifier). This auxiliary emulsifier is gradually added at the ordinary temperature, say about 60 F., to mineral oil of h gher viscosity such as cylinder oil, while both are being stirred, in such a way that the petrolene content of the said auxiliary emulsifier is 0.2% to 8% in weight of the constituent lubricating mineral oil.
Then, some quantity, say, 1% to 60% of lime Water is also gradually added thereto, as it is stirred at the ordinary temperature. Thus, the emulsification is effected,
The lubricant thus obtained can also be kept in an emulsified state for a lon period and can itself be used as a substitute or ordimar cylinder oils.
enerally, far less time is required for this operation, especially in winter, if petrolene is dissolved in the mineral oil heated to a higher temperature than at the ordinary room temperature of, say, 60 F.
One of the main features of the present invention is that the mixture with lime Water is emulsified and can be used as a substitute for lubricating mineral oil. Lubricat ng 86 mineral oil can be saved about in so much as limewater is added, which economizes the consumption of lubricant considerably.
We claim.
1. A lubricant cons sting of lubricating 00 mineral oil and 0.2% to 8% of pctrolene.
2. The method of preparing a lubricant which consists in dissolving a lubricating mineral oil of relatively low viscosity wth 10% to 40% petrolene and then adding thereto enough lubricating mineral oil of relatively higher viscosity to reduce the percentage of petroleneto 0.2% to 8%.
3. The method of preparing a lubrican which consists in dissolving lubricating mineral oil of relatively lower viscosity, for example, machine oil, with petrolene and then adding thereto lubricating mineral oil .of a higher viscosity, as cylinder oil, the 6 amount of petrolene in the final product being between 0.2% and 8% of the total'mixture. 4. The method of preparing a lubricant which consists in adding 10 to 40% by weight petrolene to lubricatin mineraltoil 10 of low viscosity, stirring and issolving the mixture, adding the mixture to oil of higher viscosity in proportions so that the quantity of petrolene contained therein is from 0.2% to 8% and then adding a quantity of lime 15 water and stirring the same for emulsification. 1
