Problems solved by technology

Green lubricating oil requires low toxicity, low pollution, and biodegradable additives, while the traditional molecular design of additives is mainly from the perspective of satisfying the performance of lubricating oil, and seldom considers factors such as environmental protection and health
The addition of additives will affect the biodegradation performance of the base oil itself, especially the active microorganisms or enzymes in the degradation process of the base oil, thus affecting the biodegradation rate of the base oil

Abstract

The invention provides a kind of environment-friendly transformer oil and the preparation method. The invention takes vegetable oil and the leftovers thereof as the materials, and is prepared after alkali refining, dehydration, esterifying alcoholysis, stopping neutralization, washing and refining, decompression and distillation, decolorization filtration; and after mixing 0.1-5.0 wt percent antioxidant and 0.1-5.0 wt percent pour inhibitor in. The high-grade fatty acid monoester content is 5-95 wt percent; the mono-substituted disubstituted, trisubstituted high-grade fatty acid glyceride contents are 5-95 percent. The appearance of the environment-friendly transformer oil is light-yellow transparent liquid, the kinematic viscosity at 50 DEG C is 2-8mm2 / s, the breakdown tension is 40-90KV / 2.5mm, and the specific inductive capacity is 2.3-3.2. The environment-friendly transformer oil does not contain sulfur, is innoxious, has high natural decomposability, and can reduce environmental pollution.

Description

technical field [0001] The invention relates to an environment-friendly transformer oil and a preparation method thereof, in particular to an environment-friendly transformer oil using vegetable oil and leftovers as raw materials and a preparation method thereof. Background technique [0002] Nowadays, except for some of the lubricants used in the world that are normally consumed by machinery and partially recycled, the rest directly flow into the environment. The European Community alone has 600,000 tons of lubricants flowing into the environment every year. The lubricant flowing into the environment seriously pollutes the land, rivers and lakes, which not only causes the loss of natural resources, but also affects the ecological environment and ecological balance. [0003] With the gradual shortage of petroleum resources and the increasingly stringent environmental protection requirements, people have re-emphasized the development and application of animal and vegetable oi...
