Green and environment-friendly water-based hydraulic fluid

Abstract

The invention provides green and environment-friendly water-based hydraulic fluid. The water-based hydraulic fluid comprises, in weight ratio, 57-65% of deionized water, 25-32% of propylene glycol, 8% of thickening agents (polyethylene glycol), 2% of lubricants (triethylene glycol coupling agents), 0.4% of water-soluble molybdenum extreme-pressure agents and 0.6% of anti-rusting agents (triethanolamine phosphate). The green and environment-friendly water-based hydraulic fluid is non-flammable, a main component of the water-based hydraulic fluid is water, helper components of the water-based hydraulic fluid do not contain nitrite or benzene series toxic compounds and absolutely do not contain toxic substances, and the vast majority of the helper components can be decomposed by microorganisms in a short time. The water-based hydraulic fluid is mainly used in a flammable and explosive production environment, is specially used for a hydraulic system, is applicable to hydraulic equipment for coal mining and petrochemical industries, and replaces current hydraulic oil synthesized with refined mineral oil or polyolefin.

Description

technical field [0001] The invention relates to hydraulic oil, in particular to a green and environment-friendly water-based hydraulic fluid. Background technique [0002] The common characteristics of hydraulic oil are flammability and poor biodegradability, the additives contained in it have certain toxicity, and the leakage is harmful to the surrounding environment. Coupled with the continuous reduction of oil resources, people's awareness of environmental protection and environmental protection legislation are increasingly strengthened, forcing us to develop more environmentally friendly and non-polluting hydraulic oil substitutes. [0003] At present, the water-based hydraulic fluid produced in China does not consider the content of toxic substances, the ability of microorganisms to decompose under natural conditions, and the decomposition speed, because the water-based hydraulic fluid is compatible with water and easily pollutes water bodies.

Problems solved by technology

[0003] At present, the water-based hydraulic fluid produced in China does not consider the content of toxic substances, microbial decomposition ability and decomposition speed under natural conditions, because water-based hydraulic fluid can be recognized with water The ratio is compatible, and it is easy to pollute the water body

[0004] Patent No. 99119283.4 "Water-based Hydraulic Fluid Composition" contains C6~C24 fatty acids Although ethanolamine salt and water have good anti-friction performance and anti-wear performance, and the anti-wear performance is stable, the friction coefficient is small, and the oil film strength is high, but the fatty acid ethanolamine salt is very easy to pollute the water body
