Embodiment 1

[0015] According to the dosage ratio, add 38% dithiocarbamate and 50% sulfurized olefin cottonseed oil into the reactor, stir for 15 minutes, continue to add 8% barium dinonylnaphthalenesulfonate, and heat to control the temperature at 60-65°C. and stirred for 30 minutes, then added 4% benzotriazole, stirred for 60 minutes, stirred evenly and stood still for 30 minutes to obtain the product. The base oil is stirred and heated to 60°C, and the product is put into the base oil at a dosage of 3% and stirred evenly, which can obtain better lubricity, rust resistance and oxidation resistance, which are significantly better than base oil. The test values ​​are as follows:

Embodiment 2

[0021] According to the dosage ratio, add 30% dithiocarbamate and 44% sulfurized olefin cottonseed oil into the reactor, stir for 15 minutes, continue to add 12% dinonylnaphthalene barium sulfonate, and heat to control the temperature at 60-65°C. And stir for 30 minutes, then add 14% benzotriazole, stir for 60 minutes, stir well and let stand for 30 minutes to obtain the product. The base oil is stirred and heated to 60°C, and the product is put into the base oil according to the dosage of 2% and stirred evenly, and better lubricity, rust resistance and oxidation resistance can be obtained, which are significantly better than base oil. The test values ​​are as follows:

Abstract

The invention relates to a composite functional additive for synthesizing ester-type flame-retardant hydraulic fluid and a preparation method of the composite functional additive and belongs to the technical field of transmission media for coal mining equipment. The composite functional additive is prepared from the following main raw materials in percentage by weight (wt%): 30-38% of dithiocarbamate, 44-50% of sulfurized olefin cottonseed oil, 8-18% of dinonylnaphthalene barium sulfonate and 3-15% of benzotriazole. The preparation method comprises the following steps of adding dithiocarbamate and sulfurized olefin cottonseed oil into a reactor, uniformly stirring, adding dinonylnaphthalene barium sulfonate, heating and stirring at 60-65 DEG C, carrying out thermal reaction for 30 minutes, adding benzotriazole, uniformly stirring for 60 minutes and standing for 30 minutes to obtain the product. The composite functional additive has corrosion-inhibiting, lubricating and anti-oxidant effects, has good solubility in the base oil and is long-term effective.

Description

technical field [0001] The invention relates to a composite additive for synthesizing ester-type flame retardant hydraulic fluid and a preparation method thereof, belonging to the technical field of transmission media for coal mining equipment. Background technique [0002] Synthetic ester-type flame retardant hydraulic fluids usually use organic polyol ester compounds as base oils, and add high-efficiency and multi-functional additives to them, which can have high flash point, high ignition point, low evaporation loss, high viscosity index, corrosion resistance, lubricity and It has excellent material adaptability and other properties, and its service life can be as long as more than 20,000 hours. It is a good replacement product for mineral oil lubricating oil used in underground mines. [0003] At present, foreign countries have started the research and development of synthetic ester-type flame-retardant hydraulic fluids for coal mines, and my country's underground machin...
