Abstract

A lubricating MoS2 oil containing MoS2 (4-10 wt.%) is prepared from Mo dissolved solid oil and basic lubricating oil through emulsifying, deposition, mixing, dissolving and mingling. Its advantages include excellent high-temp performance (120 deg.C for 48 hrs without layering, deposit and suspension and high ordinary-temp stability (ordinary temp and ordinary pressure for 30 days without layering, deposit and suspension).

Description

Lubricating MoS 2 oil

The present invention relates to a kind of Chemicals, particularly a kind of lubricating MoS 2 oil.

Existing lubricating oil mainly is to add various additive blendings with lubricant base to form, and various SAE number and purposes are seen " newly organized petroleum goods knowledge handbook ", and various additives can be found in " tensio-active agent is used complete works of "; Molybdenumdisulphide is a kind of solid lubricant, and its stability is very high, is insoluble to oil, and it is used mainly to be limited to and makes an addition in the lubricating grease or directly add in the mechanical means fuel tank, and its defective is easy precipitation fault such as result in blockage, and can not make processed oil to sell; The external oily molten Mo of producing all is liquid products, and it is too low to make an addition in the lubricating oil molybdenum content, and DeGrain, the molten molybdenum product of solid oil that Yongning Organic Chemical Plant produces, molybdenumdisulphide content be more than 99%, but only uses as solid lubricant.

The purpose of this invention is to provide that the molten molybdenum content of a kind of oil is higher, lubricant effect is better, close that the oil back stablize, is not precipitated, layering, suspend, can be made into the lubricating MoS 2 oil of commodity lubricating MoS 2 oil sale.

The present invention realizes by following scheme:

A kind of lubricating MoS 2 oil, its outward appearance is that light blue ash is to deep blue gray stable oily liquids, its molybdenumdisulphide content is 4-10% (weight), its liquid is not stratified, do not precipitate, do not suspend, its production method be with molten molybdenum of solid oil and lubricant base be raw material by emulsification, precipitate, close oil, miscible, total blending is made;

The molten molybdenum of said fixing oil is to make by catalytic reduction method, its oily molten molybdenum content 〉=99%, and moisture content≤0.5, outward appearance is blue grey black look, has the powder China ink of metalluster, 325 screen residues≤0.5%, percentage 〉=95% of oily molten molybdenum granularity≤2.3 μ.

Effect of the present invention is embodied on the following index: the product high temperature stability performance: do not have in 120 ℃, 48 hours precipitation, not stratified, suspend; Stability in storage: under normal temperature, the normal pressure, deposit 30 days, not stratified, do not have precipitation, suspend; Last non seizure load Pb, N, (test method: SH/T0202), other each index meets the GB GB greater than 520.

Below the present invention is described in more detail.

The molten molybdenum of solid oil that adopts Yongning Organic Chemical Plant to produce, the quality index of the molten molybdenum of this oil is: oily molten molybdenum content 〉=99%, oily molten molybdenum granularity: the percentage of≤2.3 μ 〉=95%; Screenings (by 325 eye mesh screens)≤0.5%, moisture content≤0.5%, the blue grey black look of outward appearance has metalluster powder China ink; The molten molybdenum of above-mentioned solid oil and parts of lubricating oil base oil circulating emulsion in colloidal mill, staticly settle after the emulsification, remove post precipitation and mix (abbreviation closes oil) with residue lubricating oil again, stir evenly the back and add other traditional lubrication oil additive again according to different purposes, promptly make finished product, the finished product outward appearance is light blue grey to deep blue grey, according to the purposes difference, the content of the molten molybdenum of oil is between 4-10% (weight), this lubricating oil can be used as I. C. engine oil, gear oil, hydraulic efficiency oil, the steam turbine wet goods, the processed oil standing storage is not stratified, there is not precipitation, suspend, the present invention can be used as tank oil and sells, and the molten molybdenum of main raw material(s) solid oil is that Yongning county Organic Chemical Plant produces.

Claims

1. lubricating MoS 2 oil, it is characterized in that its outward appearance is that light blue ash is to deep blue gray stable oily liquids, its molybdenumdisulphide content is 4%-10% (weight), liquid is not stratified, do not precipitate, suspend, its production method be with molten molybdenum of solid oil and lubricant base be raw material by emulsification, precipitate, close oil, miscible, total blending is made.

2. lubricating MoS 2 oil according to claim 1, it is characterized in that the molten molybdenum of its used solid oil makes by catalytic reduction method, its oily molten molybdenum content 〉=99%, moisture content≤0.5, outward appearance is blue grey blackization, powder China ink with metalluster, 325 screen residues≤0.5%, percentage 〉=95% of oily molten molybdenum granularity≤2.3 μ.
