preparation example Construction

[0032] The preparation method of an environment-friendly high ignition point transformer oil of the present invention comprises the following steps: heating the high oleic acid rapeseed oil to 50-80°C, adding antioxidants and metal deactivators in sequence, stirring, and mixing for 1-5 hours , after cooling and fine filtration, the product is obtained.

[0033] Specifically, when mixing, the mixing time is 2-4 hours, and when cooling, cool to room temperature.

Embodiment 1

[0035] Heat 50.0Kg of high oleic rapeseed oil to 60°C, add 0.2Kg of antioxidant 2,6-di-tert-butylsulfide phenol derivative (CibaL115) and 0.05Kg of metal deactivator benzotriazole (CibaBTAM) Add it into high oleic rapeseed oil, stir for 5 hours, cool to room temperature, and fine filter to obtain the product.

Embodiment 2

[0037] Heat 50.0Kg of high oleic rapeseed oil to 80°C, add 0.02Kg of antioxidant 2,6-di-tert-butyl-p-cresol derivative (CibaL135), 0.03Kg of antioxidant alkylated diphenylamine (CibaL01) and 0.20 Kg of metal deactivator benzotriazole (CibaBTAM) was added to high oleic rapeseed oil, stirred for 2 hours, cooled to room temperature, finely filtered to obtain the product.

Abstract

The invention discloses environment-friendly type transformer oil with a high ignition point and a preparation method of the transformer oil and belongs to the technical field of lubricating oil. The environment-friendly type transformer oil with the high ignition point comprises components in percentage by weight as follows: 99.5%-99.8% of high-oleic rapeseed oil, 0.1%-0.4% of an antioxidant and 0.1%-0.4% of a metal deactivator. The invention further provides a preparation method of the transformer oil. The preparation method comprises steps as follows: the high-oleic rapeseed oil is heated to 50-80 DEG C, the antioxidant and the metal deactivator are added sequentially, the materials are stirred and mixed for 1-5 h, and the transformer oil is obtained after cooling and refined filtration. The transformer oil adopts a simple process, does not contain harmful substances, is biodegradable and cannot damage the environment and the human body; the performance is stable, good stability is kept between different batches, the ignition point is high, and risks of fire disasters and explosions are effectively reduced; the addition quantity of the antioxidant is low, the service period is long, and the transformer oil has excellent physicochemical and dielectric properties and meets the requirement of national standard.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, in particular to an environment-friendly high ignition point transformer oil and a preparation method thereof. Background technique [0002] Mineral transformer oil has excellent electrical insulation properties, low-temperature flow properties and oxidation resistance, and is widely used in oil-filled electrical equipment such as transformers. It is currently the most widely used liquid insulating material. With the intensification of the energy crisis and the enhancement of human awareness of environmental protection, the disadvantages of mineral oil, such as non-renewable, low flash point and difficult biodegradation, have become increasingly prominent. Therefore, the development of environmentally friendly high flash point liquid insulating media with renewable, high flash point and good biodegradability has become a current research hotspot. [0003] Vegetable insulating oil is an i...
