A kind of anti-friction synergist of rotary kiln supporting wheel bearing pad lubricating oil and preparation method thereof

Abstract

The invention discloses a friction-reducing synergist and a preparation method thereof for the lubricating oil of the supporting wheel bearing bush of a rotary kiln. The mass ratio of each component is as follows: 40-60 parts of polybutene synthetic oil, 20-40 parts of nano molybdenum disulfide 8-17 parts of plastic mixture, 8-12 parts of nano-alumina, 4-6 parts of nano-titanium oxide, 4-6 parts of nano-copper, 2-3 parts of nano-nickel, 6-8 parts of composite antioxidant mixture, poly 3-8 parts of isobutylene and ethylene propylene rubber mixture, wherein the plastic mixture is a mixture of nano polytetrafluoroethylene, polyphenylene sulfide powder and polyimide powder. The beneficial effects of the present invention are: excellent resistance to extreme pressure and wear, low temperature fluidity, high temperature resistance, water shower resistance, anti-oxidation performance and anti-rust and anti-corrosion properties, which can fully repair bearing pad wear, reduce bearing pad heating, and hold pad. , even tile overturning and other phenomena, reduce wear and tear, prolong the service life of the supporting wheel bearing bush, and achieve the purpose of saving energy and reducing consumption; it is easy to operate during use.

Description

technical field [0001] The invention relates to lubricating oil, and more particularly relates to a friction-reducing synergist for the lubricating oil of the supporting wheel of a rotary kiln and a preparation method thereof. Background technique [0002] Rotary kiln is widely used in cement plants and aluminum plants. Its operation directly affects the production capacity and operating efficiency of the entire plant. Its characteristics are: heavy load, slow speed, high temperature, large temperature difference, open-air operation, long-term Operate under harsh environmental conditions. The rotary kiln is lined with refractory bricks, the sintering temperature is thousands of degrees, and the total weight of the kiln body is hundreds of tons. It is supported by six supporting rollers. On average, each bearing pad of a supporting wheel bears a load of tens of tons, and the bearing pads of the supporting roller are often subjected to impact loads and Adjustment effects. ...

AI Technical Summary

Problems solved by technology

[0007] Now most of the rotary kiln's supporting rollers and supporting roller bearing bushes are lubricated with 38# or 65# cylinder oil, because the cylinder oil in such a case the lubricating oil film becomes thinner, the oxidation is accelerated and it is emulsified with water, it is difficult to operate under high load and high temperature Under normal circumstances, effective lubrication is formed to ensure the normal operation of the bearing pad of the supporting wheel. The bearing pad of the supporting wheel is in a state of severe wear, and phenomena such as wire drawing, heat generation, tile clinging, and even tile overturning often occur on the bearing pad, and the kiln has to be shut down for overhaul, disrupting the normal operation. production order, resulting in significant loss of manpower, material and financial resources

The lubricating problem of bearing pads of supporting rollers has been difficult to solve for a long time, but there are not many good lubricating oils for bearing pads of supporting rollers. Lubricate to maintain the normal production of the rotary kiln
