Ester flame-proof hydraulic-oil containing nano abrasion-resistant additive and production method thereof

Abstract

The invention relates to ester type flame retardant hydraulic oil containing nano antiwear additive. The mixture ratio by weight of the raw materials is that: 90-95 percent of synthetic ester compoundbase oil, 1.0-5.0 percent of synthetic multifunctional additive and 1.0-5.0 percent of nano antiwear additive. The production method is that: first, the synthetic ester compound base oil is heated upto 100-120 DEG C, antioxidant is added and stirred for 1-2 hours at 100-120 DEG C until the solid is completely dissolved, then antirust agent and demulsifying agent are added, finally the finished products are filtered to be used; second, the synthetic ester compound base oil is heated up to 60-80 DEG C, and the synthetic multifunctional additive, the nano antiwear additive and antifoamer are added and stirred for 1-3 hours at a constant temperature of 60-80 DEG C, then heating is stopped, and sample is selected for analysis and packaged into finished products after the analysis. The beneficial effects of the invention are that: high temperature using performance and long time lubricant performance of the products are greatly promoted, the service life of hydraulic systems and oil changeperiod can be greatly prolonged.

Description

technical field [0001] The invention relates to the field of hydraulic oil, and mainly relates to an ester-type flame-retardant hydraulic oil containing nano anti-wear additives and a production method, which is suitable for hydraulic systems in metallurgy, automobile manufacturing, mines, power plants, etc. that are prone to fire when exposed to open flames. Background technique [0002] Since the advent of nanomaterials in the 1980s, due to their properties in the fields of electricity, force, magnetism, heat, light, chemistry and corrosion, the scope of research and application of nanomaterials has been continuously expanding. In the field of lubricating oil and grease, due to the characteristics of large specific surface area, good diffusivity, easy sintering, and low melting point of nano-lubricating materials, new lubricating materials based on nano-materials are used in friction systems, which will be different from traditional lubricating materials. The mode of actio...

AI Technical Summary

Problems solved by technology

Before the 1970s, countries were mainly committed to the development of chlorinated hydrocarbon type, phosphate ester type fire-resistant hydraulic oil, water-containing emulsion (W / O type or O / W type) and water-ethylene glycol type fire-resistant hydraulic oil, although These fire-resistant hydraulic oils are still the main body of fire-resistant hydraulic oils, but due to the limitations of operating temperature, operating pressure, material adaptability, safety and environmental protection, they can no longer fully meet the requirements of modern industries.

[0007] (2) It is easy to cause metal corrosion of the hydraulic system

When sulfur-containing and phosphorus-containing compounds are decomposed by heat, acidic substances will be produced, and these acidic substances will react with metals, resulting in metal corrosion problems

[0008] (3) The friction parts of the hydraulic system wear quickly

Due to the rapid decomposition and consumption of anti-wear extreme pressure additives, it is difficult to ensure good lubrication of the friction parts of the hydraulic system, resulting in rapid wear of the friction parts of the hydraulic system and short equipment life

[0009] (4) The oil change cycle of hydraulic oil is short, and the cost of oil products is high
