Problems solved by technology

[0003] Among them, silicone grease is widely used in many industrial product parts due to its excellent comprehensive performance, but the silicone grease sold and used in the market still has low lubricating performance, dielectric constant and dielectric loss. High, poor electrical performance, poor stability and extreme fluidity and other defects, these defects greatly limit the use of silicone grease space, reduce its market added value; High-quality products bring safety hazards, shorten the service life of some high-precision instruments, cause waste of social resources, and increase social costs

Embodiment 1

[0036] A silicone lubricating grease; containing by mass percentage: 74% of methyl silicone oil, 1% of polyisobutylene, and 25% of fumed silicon dioxide.

[0037] The preparation method is as follows:

[0038] Weigh the above amount of methyl silicone oil; first control the stirring at 2000rpm for 30 minutes, then reduce the speed to 500rpm within 10 minutes, add the above amount of polyisobutylene into the methyl silicone oil and stir evenly, then adjust the speed to 1900rpm and stir at high speed for 10 minutes; Then adjust the speed back to 400rpm, add hydrophilic and lipophilic modified fumed silica within 20min, then increase the speed to 1500rpm and stir for 40min, cool the sample to the laboratory temperature, and pass through a colloid mill and two three-roller processing , to obtain the final silicone grease.

Embodiment 2

[0040] A silicone grease; containing by mass percentage: methyl silicone oil and polyester 70%, polytetrafluoroethylene 5% and fumed silicon dioxide 25%.

[0041] The preparation method is as follows:

[0042] Weigh the above amount of methyl silicone oil and polyester, the ratio is 5:1, first control at 2000rpm and stir for 30min, then reduce the speed to 500rpm within 10min, add the above amount of polytetrafluoroethylene into methyl silicone oil and polytetrafluoroethylene Stir evenly in the mixed oil of ester, then adjust the speed to 1900rpm and stir at high speed for 10min; Cool to laboratory temperature, pass through a colloid mill and two three-roll mills to obtain the final silicone grease.

Embodiment 3

[0044] A silicone lubricating grease; comprising: 80% of methyl silicone oil and polyether, 6% of polytetrafluoroethylene and polyisobutylene, and 14% of fumed silicon dioxide calculated by mass percentage;

[0045] The preparation method is as follows:

[0046]Weigh the above amount of methyl silicone oil and polyether, the ratio is 5:1, first control at 2200rpm and stir for 30min, then reduce the speed to 485rpm, within 10min, add the above amount of polytetrafluoroethylene and polyisobutylene into the formaldehyde Stir evenly in the mixed oil of base silicone oil and polyether, in which polytetrafluoroethylene accounts for 5% of the total mass, polyisobutylene 1%, and then adjust the speed to 1920rpm and stir for 10min; then adjust the speed back to 400rpm and add hydrophilic and hydrophilic The oil-modified fumed silica was stirred at an increased speed of 1510rpm for 40 minutes, the sample was cooled to laboratory temperature, and the final silicone grease was obtained th...

Abstract

The invention relates to the technical field of lubricating grease, in particular to organic silicon lubricating grease and a preparation method thereof. The organic silicon lubricating grease comprises the following components in percentage by mass: 10 to 80 percent of base oil, 1 to 30 percent of modifier and 5 to 25 percent of thickening agent. The organic silicon lubricating grease has the advantages of wide application range, excellent dielectric property, insulating property, sealing property, thermal stability, shockproof property and lubricating property, and obvious improvement on lubricating property and thermal stability particularly.

Description

Technical field: [0001] The invention relates to the technical field of lubricating grease, in particular to a silicone lubricating grease and a preparation method thereof. Background technique: [0002] The rapid progress of science and technology has brought about the rapid development of modern industry. Especially in the 21st century, due to the continuous consumption of world resources, all countries have implemented the strategy of "high, refined and advanced" industries, making modern industrial products gradually realize multi- The integration of various practical technologies has prompted the industrial production industries all over the world to put forward higher requirements for the comprehensive performance of lubricating greases. Greases with single performance or low comprehensive performance can no longer meet the needs of modern industry. Due to the late start of my country's lubricating grease industry, the lack of independent technology research, and the r...
