Process formula of micro-emulsion water-in-oil fire resistant hydraulic fluid

Abstract

The invention relates to the chemical formula process and in particular relates to a process formula of a micro-emulsion water-in-oil fire resistant hydraulic fluid. The process formula is characterized in that the hydraulic fluid comprises the following components by weight percent: 50% of mineral oil, 12% of micro-emulsifier, 0.5% of rust preventer, 0.5% of antioxidant, 2% of extreme pressure additive and 35% of softened water. The preparation method of the hydraulic fluid comprises the following steps: mixing the mineral oil and the micro-emulsifier to be homogeneous and transparent; then adding the rust preventer, the antioxidant and the extreme pressure additive, and mixing until the solution is homogeneous and transparent; and finally adding softened water, and mixing until the solution is homogeneous and transparent. Compared with the existing emulsified water-in-oil fire resistant hydraulic fluid, the micro-emulsion water-in-oil fire resistant hydraulic fluid has the characteristics of strong lubricating property, good system stability, good rust resistance, extreme pressure property and the like, and can be used for saving more than half of the mineral oil energy.

Description

technical field [0001] The invention relates to a chemical formula process, in particular to a process formula of microemulsified water-in-oil flame retardant hydraulic fluid Background technique [0002] The main components of the existing emulsified water-in-oil fire-resistant hydraulic fluid are composed of mineral oil, emulsifier, rust inhibitor, antioxidant and softened water. Mineral oil and water containing emulsifier form a water-in-oil unstable system. Emulsions, mineral oil and water are more or less separated into two phases, and its disadvantages are that the flame retardant hydraulic fluid system is unstable, the amount of mineral oil is large, the lubricating performance is poor, and the rust resistance and extreme pressure performance are poor. Contents of the invention [0003] The present invention needs to solve the technical problems of the emulsified flame retardant hydraulic fluid, and provides a technical formula of the microemulsified water-in-oil fl...
