High-viscosity water-based rust-proof and anti-flame hydraulic oil and preparation technology thereof

Abstract

The invention discloses a high-viscosity water-based rust-proof and anti-flame hydraulic oil and a preparation technology thereof. The high-viscosity water-based rust-proof and anti-flame hydraulic oil comprises a, b and c constituents, and the mass ratio of the a, b and c constituents is 1:1.5:2. The a constituent comprises an A constituent and a B constituent, wherein the A constituent comprises the following constituents in parts by weight: one part of sodium dodecyl benzene sulfonate, 4 parts of monopotassium phosphate, 3 parts of sulfurized calcium alkyl phenolate, 26 parts of sodium citrate, 16 parts of polyacrylamide and 15 parts of nanometer borate; and the B constituent comprises 8 parts of polyacrylamide, 9 parts of phosphoric acid, 11 parts of polysorbate, 12 parts of glycerine, 16 parts of polyethylene glycol and 15 parts of monopotassium phosphate. The b constituent comprises 31 parts of sulfurized isobutylene, 18 parts of epoxidized vegetable oil, 24 parts of lupeol palmitate, 16 parts of poly-n-butyl vinyl ether and 11 parts of polymethacrylate. The hydraulic oil is green and environmentally-friendly; the production process is safe; meanwhile, the constituent ratio is stable; and the prepared water-based rust-proof and anti-flame hydraulic oil has excellent anti-flame performance, lubricating performance and anti-rust property.

Description

technical field [0001] The invention relates to the technical field of hydraulic equipment, in particular to a high-viscosity water-based anti-rust and fire-resistant hydraulic oil and a preparation process thereof. Background technique [0002] In the field of hydraulic oil production, due to the lack of performance and sources of mineral oil base oils, non-petroleum hydraulic oils have been more widely and deeply used. At present, the most widely used fire-resistant hydraulic oil is water-ethylene glycol Liquid, but it has problems such as corrosion of metal, poor lubricity, flame resistance and wear resistance, and long defoaming time in use, which limits the scope of application of fire-resistant hydraulic oil to a certain extent, and the existing water-based The preparation process of fire-resistant hydraulic oil is mostly direct heating reaction and simple filtration, resulting in low cleanliness of water-based fire-resistant hydraulic oil. [0003] In Europe and Nort...
