Problems solved by technology

[0003] Nowadays, when preparing lubricating oil, wear-resistant additives such as silica are generally added. These wear-resistant additives have poor compatibility with lubricating oil and are easy to agglomerate in lubricating oil. Not only cannot improve its anti-wear performance, but will Reduce its use effect, and at the same time, the direction of biodegradation is also a topic of our concern

Abstract

The invention discloses a biodegradable composite lubricating oil and a preparation process thereof. The raw materials of each component of the composite lubricating oil include: by weight, 4-6 parts of modified wear-resistant materials, 3-4 parts of additives, phosphoric acid 10-15 parts, n-stearyl alcohol 15-18 parts, vegetable oil 30-40 parts, oleic acid surfactant 2-3 parts, antioxidant 2-3 parts, extreme pressure agent 2-3 parts, defoamer 1 -2 parts, 5-6 parts of viscosity regulator, 15-20 parts of water; the vegetable oil includes castor oil and cottonseed oil, and the mass ratio of castor oil and cottonseed oil is 1:1; the modified anti-wear agent It is an oil-soluble microsphere, and the microsphere is mainly made of silica-coated filler. The invention discloses a biodegradable composite lubricating oil and its preparation process. The process design is reasonable and the operation is simple. The prepared lubricating oil has excellent anti-wear and anti-friction properties, good lubricating performance, good storage stability, and can be biodegradable. Degradation, will not destroy the ecological environment, practical and environmentally friendly.

Description

Technical field [0001] The present invention relates to the field of lubricating oil technology, specifically a biodegradable composite lubricating oil and the preparation process thereof. Background [0002] With the progress and development of science and technology, we pay more and more attention to environmental pollution, green environmental protection has become the development direction we have been providing, and for lubricating oil, the research and development of a biodegradable, sustainable development of green lubricants has also become one of our main research directions. [0003] Nowadays, when preparing lubricating oil, silica and other wear-resistant additives are generally added, these wear-resistant additives have poor compatibility with lubricating oil, and are easy to agglomerate in lubricating oil, which not only cannot improve its anti-wear performance, but will reduce its use effect, and at the same time, for the direction of biodegradation, it is also a t...
