Abstract

Lube oil additive of the invention is characterized in that, it is the lube oil additive for making an addition to lubricating oil, and it includes sulfonic acid calcium salt, polyalphaolefin oligomer, zinc dithiophosphate system antioxidant, succinimide, thiadiazoles system extreme pressure agent and the phenolic antioxidants of the calcium carbonate comprising calcite crystal structure that the content in the polyol ester system synthetic base oil that the content in the lube oil additive is 30.0 weight of weight %~60 %, the lube oil additive is 5.0 weight of weight %~30.0 %.

Description

The manufacturing method of lube oil additive and lube oil additive
Introduce reference
This application claims 2 months 2017 Japanese patent application laid filed in 22 days to be willing to the priority of 2017-31602, passes through The application is introduced with reference to its content.
Technical field
The present invention relates to the manufacturing methods of additive for lubricant and lube oil additive.
Background technique
Conventionally, there is known for making engine, gear (speed changer), differential gearing (differential gear) of the vehicles such as automobile etc. The lubricating oil successfully acted on.Consider from the purpose for the greasy property for strengthening, improving lubricating oil, is matched according to the purposes of lubricating oil Close various additives.Additive for lubricant (hereinafter also referred to as " lube oil additive ") can enumerate antiwear additive, friction Regulator, detergent-dispersant additive, viscosity index improving agent, extreme pressure agent, antioxidant etc..Moreover, according to the purposes of lubricating oil from this Selection is suitable for the additive of the purposes to cooperate in a little multiple additives.With regard to such lube oil additive, various hairs have been carried out Bright (referring for example to patent document 1,2).
Patent document 1 discloses a kind of lube oil additive, includes the high molecular weight for dissolving in lube base oil Lubrication portion；And a pair of of suction with the functional group that can be adsorbed with material and in a manner of clamping lubrication portion in conjunction with lubrication portion Attached portion.According to the technology of patent document 1, a pair of of adsorption section and material adsorb, and dissolve in base oil by what each adsorption section clamped The lubrication portion of high molecular weight also remains between material.Lubrication portion, each adsorption section between the material are sent out as oiliness enhancer The effect of waving, this makes it possible to obtain excellent friction reducing effects.
It is 6.00mm that patent document 2, which discloses the kinematic viscosity at 100 DEG C of one kind,2/ second lubricant oil composite below, By at least cooperating the kinematic viscosity at 100 DEG C to be 0.50~2.50mm2Movement at the dialkyl group monoether (A) of/second and 100 DEG C Viscosity is 50mm2The base oil of/poly-alpha-olefin (B) more than the second forms.According to the technology of patent document 2, following effects can be obtained Fruit: although being low viscosity, viscosity-temperature profile, low temperature flow and evaporation characteristic are excellent, shear stability and oxidation-stabilized Property is good, and the organic materials such as rubber are not easy to be swollen.

Summary of the invention
Problems to be solved by the invention
In addition, as described above, lube oil additive from multiple additives by selecting adding for the purposes for being suitable for lubricating oil Add agent and is generated to cooperate.Thus, for example cylinder oil additive is different from lubricant for gears additive, engine It may not can become the lube oil additive suitable for gear with lube oil additive.Therefore, lubricating oil is applied to vehicle in user Each device in the case where, there are problems that must to each device prepare lube oil additive.
On the other hand, as shown in the technology for being recorded in above patent document 1,2, existing invention is usually intended to improve individual The invention of the performance of lube oil additive etc. can not solve the above problems.
The present invention has been made in view of the above problems, its object is to: offer can synthetically be applied to various uses Lubricating oil lube oil additive and lube oil additive manufacturing method.
