[0038] The existing multi-grade hydraulic oil products used in hydraulic systems are called high-viscosity index hydraulic oils, including HV and HS hydraulic oils. Due to their high viscosity index (viscosity index not less than 150), they have good low-temperature The starting performance can reduce the loss of working efficiency of the hydraulic oil, so the low temperature also has a certain energy-saving effect.

Abstract

The invention provides a high efficiency hydraulic oil composition, which is composed of the following components by weight: 0.2-0.3% of alkyl diphenylamine; 0.3-0.5% of a liquid phenol type antioxidant; 0.8-1.2% of an antiwear hydraulic oil multifunctional additive; 13-17% of polymethacrylate; 0.03-0.1% of phenothiazine; and the balance base oil. The high efficiency hydraulic oil composition provided by the invention has a very high viscosity index, and also has excellent high antioxidant properties. Compared with common HM hydraulic oil (with a viscosity index of 100), the high efficiency hydraulic oil composition has an energy saving effect of more than 5%. Also, the product provided by the invention has the advantages of reasonable compatibility of raw materials, simple preparation method, wide application range, and easily available raw materials. The high efficiency hydraulic oil composition provided by the invention has product performance significantly superior to that of similar products at home and abroad, and is suitable for the hydraulic systems of various industrial equipment, engineering machineries, metallurgical machineries, etc.

Description

technical field [0001] The invention relates to a high-efficiency and energy-saving lubricating oil composition, in particular to a high-efficiency and energy-saving hydraulic oil, which is suitable for hydraulic systems of various industrial equipment, engineering machinery, metallurgical machinery, etc., and belongs to the field of chemical industry. Background technique [0002] The level of energy consumption is a comprehensive reflection of a country's economic structure, growth mode, technological level, management ability, consumption pattern and national quality. The country's "Eleventh Five-Year Plan" "Outline" further set the "Eleventh Five-Year Plan" period to reduce energy consumption per unit of GDP by about 20% as a binding target, and six measures must be taken to save energy. "Energy saving through technological progress" is listed into it. Energy conservation is at the core of China's energy strategy and policies. my country's energy utilization efficiency...
