Problems solved by technology

The high anti-wear properties of lubricating grease are challenged by some machinery and equipment, so human beings are required to prepare more anti-wear lubricating grease. At present, there are not many anti-wear additives for lubricating grease at home and abroad, and the price is very expensive. The preparation process Complicated, poor versatility, poor effect

Embodiment 1

[0018] Slideway lubricating grease, wherein the proportioning by weight of each raw material component is as follows:

[0019] Base oil (synthetic oil): 80 parts;

[0020] Soap base thickener (lithium stearate): 12 parts;

[0021] Anti-wear additive (lanthanum fluoride): 2 parts;

[0022] Anti-rust additive (dodecenyl succinic acid): 4 parts;

[0023] Antioxidant additive (lead dibutyldithiocarbamate): 2 parts.

Embodiment 2

[0025] Slideway lubricating grease, wherein the proportioning by weight of each raw material component is as follows:

[0026] Base oil (mineral oil): 94 parts;

[0027] Soap-based thickener (lithium 12-hydroxystearate): 4 parts;

[0028] Anti-wear additive (calcium acetate): 0.5 parts;

[0029] Anti-rust additive (benzotriazepam): 0.5 parts;

[0030] Antioxidant additive (diphenylamine): 1 part.

[0031] In the above-mentioned examples, the lubricating grease containing calcium acetate undergoes a tribochemical reaction under the action of higher load and frictional heat to generate CaCO 3 , CaCO 3 Further reaction to generate CaO and CaC 2 , while CaO and CaC 2 Has good anti-wear effect.

Embodiment 3

[0033] Slideway lubricating grease, wherein the proportioning by weight of each raw material component is as follows:

[0034] Base oil (mineral oil): 88 parts;

[0035] Soap base thickener (12-hydroxy lithium stearate): 8 parts;

[0036] Anti-wear additive (thiocarbamate): 0.5 parts;

[0037] Anti-rust additive (benzotriazepam): parts;

[0038] Antioxidant additive (2,4-diaminodiphenyl ether): 1 part.

Abstract

The invention relates to a slide rail lubricating grease composition which comprises the following raw material components in parts by weight: 80-94 parts of base oil, 4-12 parts of soap-base thickening agents, 0.5-2 parts of anti-abrasion additives, 0.5-8 parts of antirust additives and 1-2 parts of antioxidant additives. According to the slide rail lubricating grease composition, lanthanum fluoride, calcium acetate and thiocarbamate can reduce the friction coefficient of lubricating grease as the anti-abrasion additives; the lubricating grease which contains calcium acetate generates friction chemical reaction under the action of relatively high load and friction heat to generate CaCO3, CaCO3 further reacts to generate CaO and CaC2, and CaO and CaC2 have better anti-abrasion effects.

Description

technical field [0001] The invention relates to a lubricating grease composition, in particular to a sliding rail lubricating grease composition with good wear resistance. Background technique [0002] Grease is composed of lubricating oil, performance additives and a thickener, which is a well-dispersed system of insoluble solids that form a matrix that holds the oil in a semi-solid state. Greases have some advantages over oils because of their semi-solid consistency. Greases are easier to seal into bearings than oils; greases do not require a circulation system; and greases also act as Sealed to resist contamination. Because of these factors, grease is often the lubricant of choice for ball or roller bearings in electric motors, household appliances, bicycle wheels, mobile equipment wheel and chassis lubrication, and some industrial plain and roller bearings. [0003] However, with the development of human beings and the technical development of various machinery and equ...
