Problems solved by technology

Since open gears are semi-open or fully open, open gears require lubricating grease to have excellent water resistance, extreme pressure and anti-wear performance, adhesion performance, high and low temperature performance, and protection performance; general gear grease production process Relatively simple, the solid additive is single and dispersed unevenly, the product has poor water resistance and extreme pressure and anti-wear performance, and cannot fully meet the lubrication requirements of equipment, so it is not suitable for application on large open gears

preparation example Construction

[0024] The preparation method of the open gear waterproof grease composition provided in this example includes the following steps: After uniformly mixing the components according to the set weight percentage, heating to a temperature of 60-80°C, and then grinding to obtain the open gear Type gear waterproof grease composition; it is preferable to uniformly mix each component according to the set weight percentage, heat to a temperature of 70°C, and then grind; Stable quality, excellent water resistance and extreme pressure anti-wear performance, proper heating and grinding is beneficial to reduce the viscosity of liquid raw materials, so that solid additives can be fully ground and dispersed.

[0025] In this example, all the raw materials used can be purchased from the market.

Embodiment 1

[0028] Take 50% of composite calcium sulfonate base grease, 25% of MCA, 10% of polyisobutylene (average molecular weight is 2400), 5% of fumed silicon dioxide, and 10% of zinc oxide (1000 mesh) in the small test kettle by weight percentage , after uniform mixing, heating to a temperature of 80° C., and then putting the heated mixture into a three-roll mill to grind until the solid additives are fully dispersed, thereby obtaining an open gear waterproof grease composition.

Embodiment 2

[0030] Take 80% of composite calcium sulfonate-based grease, 16% of MCA, 2% of polyisobutylene (average molecular weight of 1300), 1% of fumed silicon dioxide, and 1% of zinc oxide (500 mesh) in the small test kettle by weight percentage , after uniform mixing, heating to a temperature of 60° C., and then putting the heated mixture into a three-roll mill to grind until the solid additives are fully dispersed, and the open gear waterproof grease composition is obtained.

Abstract

The invention provides an open gear waterproof lubricating grease composition and a preparation method thereof. The lubricating grease composition comprises, by weight, 50-80% of compound calcium sulfonate-based lubricating grease, 16-25% of MCA, 1-10% of polyisobutylene, 1-5% of fumed silica and 1-10% of zinc oxide, and the total percentage of all above raw material components is 100%. The raw materials used in the open gear waterproof lubricating grease composition have excellent performances, and have self excellent performances and mutual synergism after being added; and the components are reasonably proportioned, and mutually have synergism, so the prepared composition has stable quality, and meets use requirements of open gears. The preparation method of the open gear waterproof lubricating grease composition has the advantages of simplicity, few processes, stable product quality, and easiness in monitoring.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to an open gear waterproof lubricating grease composition and a preparation method thereof. Background technique [0002] With the improvement of manufacturing technology and management level and high requirements for the production efficiency of single machines, industrial and mining equipment has the potential to develop towards large-scale and high automation. Rotary kilns in cement plants, ball mills in metallurgical industries or mines, and sintering plants in The rotary mechanism of engineering machinery such as mixer, rotary kiln in pelletizing plant, electric shovel, and the open gear in the yaw and pitch system of wind power equipment have higher and higher requirements on the performance of lubricating grease. [0003] Open gear transmission refers to gear transmission that is fully or partially exposed to space. Due to the simple structure of open gears and goo...
