Problems solved by technology

However, the current lubricating oil is only suitable for use under light load conditions. When the mechanical equipment is under heavy load boundary friction conditions, the protective film formed by the general lubricating oil is very easy to cause wear, thus losing the ability to reduce wear and resist wear.

Embodiment 1

[0031] An anti-wear additive for lubricating oil, composed of the following components in mass percentage: base oil (mineral oil) 70%, molybdate 10%, sorbitan monooleate 3%, dipentyl disulfide 0.8% zinc carbamate, 1% nano-graphene, and the balance of additives. Among them, the additive is mixed with 20% antirust agent, 10% defoamer, and 70% extreme pressure antiwear agent. The antifoaming agent is polydimethylsilicone oil, the antirust agent is sorbitan monooleate, and the extreme pressure and antiwear agent is isobutylene sulfur.

[0032] Nano-graphene is mixed with sorbitan monooleate and then ultrasonically dispersed, and finally base oil, molybdate, dipentyl dithiocarbamate and additives are added, and the mixture is evenly stirred to obtain an anti-wear additive for lubricating oil.

[0033]

Embodiment 2

[0035] An anti-wear additive for lubricating oil, which is composed of the following components in mass percentage: 70-80% base oil (poly-α-olefin synthetic oil), 5-10% molybdate, sorbitan monooleate 1~3%, zinc diamyl dithiocarbamate 0.7~0.8%, nanographene 1~3%, additive balance, among them, the additive consists of 25% antirust agent, 12% defoamer, 63 % of extreme pressure antiwear agent, the antifoaming agent in the additive is polydimethylsilicone oil, the antirust agent is fatty acid pentaerythritol ester, and the extreme pressure antiwear agent is isobutylene sulfur.

[0036] First mix nano-graphene with sorbitan monooleate and then ultrasonically disperse, then add base oil, molybdate, dipentyl dithiocarbamate and additives, and stir evenly to obtain the lubricating oil anti-wear additive.

[0037]

Embodiment 3

[0039] An anti-wear additive for lubricating oil, consisting of the following components in mass percentage: 80% base oil, 5% molybdate, 1% sorbitan monooleate, zinc dipentyl dithiocarbamate 0.7%, nano-graphene 3%, additive balance, wherein, the additive is mixed by 30% antirust agent, 20% defoamer, 50% extreme pressure antiwear agent, and the defoamer in the additive is Polyether modified silicone oil, antirust agent is sorbitan monooleate and fatty acid pentaerythritol ester (mass ratio 1:1 mixed), extreme pressure antiwear agent is sulfurized isobutylene.

[0040] Nano-graphene is mixed with sorbitan monooleate and then ultrasonically dispersed, and finally base oil, molybdate, dipentyl dithiocarbamate and additives are added, and the mixture is evenly stirred to obtain an anti-wear additive for lubricating oil.

[0041] application:

[0042] The lubricating oil anti-wear additive of the present invention can be directly added into the lubricating oil and stirred evenly, a...

Abstract

The invention discloses a lubricating oil wear resistant additive. The lubricating oil wear resistant additive comprises, by mass, 70-80% of base oil, 5-10% of organic molybdate, 1-3% of sorbitan monooleate, 0.7-0.8% of zinc diamyldithiocarbamate, 1-3% of nanometer graphene, and the balance of additives. The lubricating oil wear resistant additive has wear resistance and reduction effects on various lubricating oils, has a restoration function, can reduce the mechanical work noise and power loss, and is suitable for any brand of machine oils, gear oils, hydraulic oils, track oils and other lubricating oils. The invention also discloses a preparation method of the lubricating oil wear resistant additive. The method comprises the following steps: mixing nanometer graphene with sorbitan monooleate, carrying out ultrasonic dispersion, adding base oil, organic molybdate, zinc diamyldithiocarbamate and the additives, and uniformly stirring. The preparation method has the advantages of simple process steps, low cost, and suitableness for industrial production.

Description

[0001] technical field [0002] The invention relates to the technical field of lubricating oil, in particular to an anti-wear additive for lubricating oil and its preparation method and application. [0003] Background technique [0004] For any mechanical equipment and means of transportation, there is friction and wear between the relative moving parts, which may cause equipment malfunction and power loss, or cause mechanical damage, consume lubricating oil, and reduce the service life of the machine. [0005] In order to ensure the normal operation of mechanical equipment and transportation tools and improve their service life, lubricating oil is usually added between relative moving parts. However, the current lubricating oil is only suitable for use under light load conditions. When mechanical equipment is under heavy load boundary friction conditions, the protective film formed by general lubricating oil is very easy to cause wear, thus losing the ability to reduce w...
