The invention provides environment-friendly high-performance cutting lubricating oil as well as a preparation method and application thereof.The environment-friendly high-performance cutting lubricating oil is prepared by taking isooctyl stearate as base oil and adding phosphate amine salt, sulfurized fatty acid ester, refined lard oil and a nano-copper composite anti-wear agent. Compared with the traditional neopentyl polyol ester, the environment-friendly high-performance cutting lubricating oil has the advantages that the cost is reduced by 50-70% under the condition that the formula is optimized, and the environment-friendly high-performance cutting lubricating oil is suitable for the field of high-precision metal processing through biological safety verification.

This invention provides a rust-preventive oil for cold-rolled grain-oriented silicon steel sheets and its preparation method, belonging to the field of metal corrosion and protection. The invention uses isooctyl oleate and / or isooctyl stearate as the base oil of the rust-preventive oil. These are low-viscosity synthetic esters, which, compared to mineral oils, exhibit excellent biodegradability under natural environmental conditions and stronger adsorption, wetting, spreading, and penetration on metal surfaces. This allows for the formation of a thicker and stronger oil film on the surface of grain-oriented silicon steel sheets, achieving more long-lasting and stable rust protection. Furthermore, the rust-preventive oil for cold-rolled grain-oriented silicon steel sheets provided by this invention does not contain barium heavy metal salts and has excellent biodegradability, making it extremely friendly to human health and the natural environment. It is an environmentally friendly rust-preventive oil, solving the pain point of traditional rust-preventive oil systems that cannot simultaneously achieve strong rust prevention and environmental friendliness.

The invention relates to environment-friendly heavy-load gear oil and a preparation method thereof, and relates to the field of preparation of heavy-load gear oil. The environment-friendly heavy-load gear oil comprises a basic component and a functional additive, the basic component is prepared from the following components in percentage by mass: 70 to 90 percent of isooctyl stearate RJ-1651 and 10 to 30 percent of isooctyl adipate RJ-1422; on the basis of the basic component, the functional additive comprises the following components in percentage by mass: 0.3%-0.7% of molybdenum dialkyl dithiophosphate (MoDTP), 1%-2% of zinc dialkyl dithiophosphate (ZnDDP), 1.5%-2.5% of molybdenum disulfide (MoS2) and 0.3%-0.7% of polytetrafluoroethylene (PTFE). Through compounding of the base oil and the synergistic effect of the four functional additives, the maximum Pb value can reach 1000N, the minimum grinding crack diameter is 0.412 mm, the maximum 28-day biodegradation rate reaches 92%, animal safety tests prove that the gear oil is nontoxic, and the problems that traditional mineral oil gear oil pollutes the environment and is insufficient in bearing capacity are fundamentally solved.

The invention discloses chlorine-free, sulfur-free and silicon-free high-speed stamping oil, and belongs to the technical field of stamping oil. The lubricating oil comprises the following components in percentage by weight: 0 to 90 percent of base oil, 0 to 5 percent of trimethylolpropane oleate, 0 to 5 percent of isooctyl palmitate, 0 to 5 percent of isooctyl stearate, 0 to 5 percent of isooctyl oleate, 0 to 5 percent of polyisobutene 1300, 0 to 5 percent of a corrosion inhibitor, 0 to 5 percent of 2, 6-di-tert-butyl-p-methylphenol and 0 to 5 percent of di-n-butyl phosphite. The invention also discloses a preparation method of the chlorine-free, sulfur-free and silicon-free high-speed stamping oil. Compared with the prior art, the cutting fluid provided by the invention has the advantages of high viscosity, good lubricity, corrosion inhibition, wide applicability and strong oxidation resistance, does not contain chlorine, sulfur and silicon, and is more environment-friendly.

The invention belongs to the field of anti-rust oil, and particularly discloses barium-free soft film anti-rust oil as well as a preparation method and application thereof. The anti-rust oil comprises the following components in percentage by mass: 13-25% of a composite barium-free corrosion inhibitor; 0.1% to 0.5% of a polyoxyethylene-polyoxypropylene copolymer; 0.3 to 0.8 percent of dodecenylsuccinic acid; 5-15% of base oil; 59-80% of alkane solvent oil; the composite barium-free corrosion inhibitor comprises calcium dinonyl naphthalene sulfonate, oxidized paraffin butyl ester, oxidized paraffin calcium soap and isooctyl stearate. The anti-rust oil disclosed by the invention can form a layer of uniform, continuous and compact ultrathin oil film on the metal surface by adopting a spraying, brushing and dip-coating method, does not generate a corrosion phenomenon within 132 hours during a salt spray test, can inhibit corrosion of a plurality of corrosive media such as chloride ions, water and oxygen to a metal material, has excellent corrosion resistance, and can be applied to the field of metal products. The method is especially suitable for corrosion prevention of precise steel parts with complex structures.
