Abstract

The invention discloses total-synthesis hydraulic oil with a super-long oil change period. The hydraulic oil is characterized by consisting of base oil, an antioxidant, a detergent, a dispersing agent, a corrosion inhibitor, an antifoaming agent, a metal deactivator, a demulsifying agent, an anti-wear agent, an anti-extreme pressure agent, a viscosity index improver and a pour point reducer. In the invention, the production scheme is simple; and the product is cheaper than other products of the same type, has high quality and can effectively and comprehensively improve the performance requirements of lubricating oil. The anti-wear and anti-extreme pressure effects are enhanced to the greatest degree while the properties of lubricating oil including oxidation resistance, corrosion resistance, cleaning and dispersion, foam resistance, rust prevention and prevention of oil sludge generation are comprehensively improved. The life cycle of the hydraulic oil is greatly prolonged, and the noise of mechanical equipment and the energy consumption are reduced. The environmental protection requirements of existing products of the same type are completely exceeded.

Description

(1) Technical field [0001] The invention relates to an industrial process lubricating oil, in particular to a preparation scheme and a manufacturing method of a fully synthetic ultra-long oil change period hydraulic oil. (2) Background technology [0002] At present, with the progress of society and the continuous innovation of science and technology, people are also improving the advanced nature of various products to varying degrees, and with the progress of society, various types of mechanical equipment are also reforming and innovating to varying degrees. The continuous innovation of various types of machinery makes all types of lubricating oils also continuously improve the quality to meet the operation requirements of various types of mechanical equipment. In particular, the scale of the machinery manufacturing industry continues to expand. In the past ten years, my country's "three basic" industries have continued to grow steadily, and the product variety and level h...
