The compounding of phenyl silicone oil with other lubricants is a complex process that requires consideration of multiple factors, including lubricant compatibility, performance requirements, and application scenarios. The following is a detailed analysis of the compounding of phenyl silicone oil with other lubricants:

1. Characteristics of phenyl silicone oil
Phenyl silicone oil is a product in which some methyl groups in methyl silicone oil are replaced by phenyl groups, and has a variety of excellent properties:

Good thermal stability: It can maintain stable lubrication performance at high temperatures.
Outstanding low temperature resistance: It has good fluidity even in low temperature environments.
Excellent lubrication performance: It can effectively reduce the friction coefficient and improve the operating efficiency of the equipment.
Chemical corrosion resistance: It has good stability to a variety of chemical substances.

2. Compounding principles with other lubricants
Compatibility:
Different lubricants may have different chemical compositions and properties, so their compatibility needs to be evaluated before compounding.
Lubricants with poor compatibility may cause performance degradation, phase separation, or adverse reactions after compounding.

Performance requirements:
Select appropriate lubricants for compounding according to application scenarios and performance requirements.
For example, in situations where high temperature stability is required, lubricants with good thermal stability can be selected to be compounded with phenyl silicone oil; in situations where low temperature fluidity is required, lubricants with good low temperature resistance can be selected.
Synergistic effect of additives:
Lubricants often contain various additives to improve their performance.
When compounding, the synergistic effect between additives needs to be considered to avoid adverse reactions or reduced performance.

3. Common compounded lubricants
PAO base oil:
PAO (polyalphaolefin) base oil is a high-performance synthetic lubricant.
Compounding with phenyl silicone oil can improve the low temperature fluidity and high temperature stability of grease.
Thickener:
Such as 12-hydroxystearate lithium, lithium stearate and organic bentonite.
These thickeners can be compounded with phenyl silicone oil to form grease, improving the curing degree, stability and lubricity of the grease.
Polytetrafluoroethylene powder:
Polytetrafluoroethylene (PTFE) powder has excellent wear resistance and chemical stability.
Compounding with phenyl silicone oil can significantly improve the wear resistance and chemical stability of grease.
Auxiliary additives:
Free radical scavengers such as di-tert-butyl-p-cresol and diphenylamine.
These additives can capture active free electrons and inhibit continuous electron loss reactions, thereby improving the low-temperature stability of greases.

4. Compounding precautions
Compounding ratio:
Different compounding ratios may result in different performance of greases.
It is necessary to determine the best compounding ratio through experiments to meet performance requirements.
Mixing uniformity:
During compounding, it is necessary to ensure that various lubricants are fully mixed and uniform.
Uneven mixing may lead to performance degradation or adverse reactions.
Storage stability:
The compounded grease needs to be stable in storage.
After long-term storage, it is necessary to evaluate again whether its performance meets the requirements.

In summary, the compounding of phenyl silicone oil with other lubricants is a complex process that requires consideration of multiple factors. Through reasonable selection and compounding, greases with excellent performance can be prepared to meet the needs of different application scenarios.
