Embodiment 1

[0022] The roller bearing grease in this example is prepared according to the following components and weight ratio: 50% base oil; 15% adhesive; 20% stearic acid; 5% anti-rust additive; Mill additive 5%; polyisobutylene additive 1%. Taking the preparation of 1000kg of roller bearing grease as an example, the weight of each component required is: 500kg of base oil; 150kg of adhesive; 200kg of stearic acid; 50kg of anti-rust additive; 40kg of anti-oxidation additive; Polyisobutylene additive 10kg.

[0023] The above-mentioned base oil includes the first base oil and the second base oil, and its weight percentage is: 25% of the first base oil; 25% of the second base oil. Therefore the weight of above-mentioned composition that needs is: first base oil 250kg; Second base oil 250kg.

[0024] The above-mentioned first base oil is a mineral base oil with a viscosity of 140 cst at a temperature of 45°C, and the above-mentioned second base oil is a mineral base oil with a viscosity o...

Embodiment 2

[0030] The roller bearing grease in this embodiment is prepared according to the following components and weight ratio: 55% base oil; 12% adhesive; 17% stearic acid; 6% anti-rust additive; Grinding additive 3.5%; polyisobutylene additive 1.5%. Taking the preparation of 1000kg roller bearing grease as an example, the weight of each component required is: base oil 550kg; adhesive 120kg; stearic acid 170kg; anti-rust additive 60kg; anti-oxidation additive 50kg; extreme pressure and anti-wear additive 35kg; Polyisobutylene additive 15kg.

[0031] The above-mentioned base oil includes the first base oil and the second base oil, and its weight percentage is: the first base oil 27.5%; the second base oil 27.5%. Therefore the weight of above-mentioned composition that needs is: first base oil 275kg; Second base oil 275kg.

[0032] The above-mentioned first base oil is a mineral base oil with a viscosity of 140 cst at a temperature of 45°C, and the above-mentioned second base oil is ...

Embodiment 3

[0038] The roller bearing grease in this example is prepared according to the following components and weight ratio: 60% base oil; 10% adhesive; 15% stearic acid; 7% anti-rust additive; 3% anti-oxidation additive; Mill additive 3%; polyisobutylene additive 2%. Taking the preparation of 1000kg of roller bearing grease as an example, the weight of each component required is: 600kg of base oil; 100kg of adhesive; 150kg of stearic acid; 70kg of anti-rust additive; 30kg of anti-oxidation additive; 30kg of extreme pressure and anti-wear additive; Polyisobutylene additive 20kg.

[0039] The above-mentioned base oil includes the first base oil and the second base oil, and its weight percentage is: the first base oil 30%; the second base oil 30%. Therefore the weight of above-mentioned composition that needs is: first base oil 300kg; Second base oil 300kg.

[0040] The above-mentioned first base oil is a mineral base oil with a viscosity of 140 cst at a temperature of 45°C, and the a...

Abstract

The invention discloses a roll bearing lubricating grease. The roll bearing lubricating grease is prepared from the following components in percentage by weight: 50-60% of base oil, 10%-15% of adhesive, 15%-20% of stearic acid, 5%-7% of antirust additive, 3%-5% of anti-oxidization additive, 3%-5% of antiwear additive at extreme pressure and 1%-2% of polyisobutene additive. Compared with the tradition roll bearing lubricating grease, the roll bearing lubricating grease is better in high temperature resistance, lubricity, water resistance and mechanical stability, and capable of meeting the lubrication requirements of high-temperature and high-load mechanical equipment.

Description

technical field [0001] The invention relates to a lubricating grease, in particular to a rolling bearing lubricating grease. Background technique [0002] 3# roller bearing grease is widely used in the continuous rolling mill, continuous casting machine, sintering machine, tapping roller table in the metallurgical industry, as well as printing and dyeing, large motors, pit cars, and hot oil pump lighting equipment for high-temperature friction and unstable lubrication. [0003] The current roll bearing lubricating grease is still insufficient in terms of high temperature performance, lubricity, water resistance and mechanical stability, and cannot meet the requirements of high temperature and heavy load mechanical equipment for lubrication. Contents of the invention [0004] The object of the present invention is to address the above problems and provide roll bearing lubricating grease that meets the lubricating requirements of high-temperature and heavy-duty mechanical eq...
