Problems solved by technology

Commonly used water-soluble inorganic rust inhibitors include nitrite, phosphate, silicate, borate, molybdate, etc. However, due to the toxicity of nitrite and phosphate, silicate and borate are not easy to dissolve. Molybdate is expensive, so it is not suitable as an anti-rust additive for new water-based lubricants

Embodiment 1

[0027] Embodiment 1: When it is suitable for lubricating sliding bearings, the method of use: when the lubricating fluid is suitable for lubricating sliding bearings, its usage is similar to ordinary lubricating oil. If the sliding bearing is a dynamic pressure sliding bearing, the method of immersing the friction pair in lubricating fluid can be used. When the main shaft rotates, due to the dynamic pressure effect, the lubricating liquid can form a bearing liquid film to ensure the normal and stable operation of the main shaft; if the sliding bearing is static pressure or For the form of dynamic and static pressure lubrication, refer to the specific sliding bearing and restrictor structure, inject a certain pressure into the sliding bearing system, form a bearing liquid film in the bearing gap, and ensure the normal and stable operation of the spindle.

[0028] Prepare 82.6kg of high-purity water in the high-purity water machine, and prepare 8kg of triethanolamine borate, 9kg ...

Embodiment 2

[0031] Embodiment 2: The method of use when it is suitable for hydrostatic guide rails: if it is used for open hydrostatic guide rails, the lubricating liquid enters the single-sided liquid chamber of the guide rail through the throttle at a certain pressure from the liquid pump, and floats the moving parts to make the guide rail When the surface moves, it is in a state of pure liquid friction and forms a bearing liquid film; if it is used in a closed static pressure guide rail, the lubricating liquid is passed through the restrictor by the liquid pump at a certain pressure, and enters multiple liquid chambers on each side of the guide rail to form a bearing liquid film , and ensure that the guide rail can still work normally under the two-way external load.

[0032] Prepare 39.5kg of high-purity water, 15kg of triethanolamine borate, 12kg of triethanolamine oleate, 1kg of triethanolamine sebacate, 32kg of ethylene glycol and 0.5kg of silicone defoamer, and then pour the above ...

Embodiment 3

[0034] Embodiment 3: Under the situation that each component of water-based lubricating fluid has been determined, test the antirust performance of the lubricating fluid, with reference to the national standard GB6144-85 (the regulation of the cutting fluid antirust performance test) as the test standard, adopt the monolithic method and The antirust performance of the lubricating fluid (experimental samples included several groups of lubricating fluids with different antirust ratios; in order to reduce the test time, a 5% diluted aqueous solution was used) was tested by lamination method. The specific test plan is as follows:

Abstract

The invention relates to viscosity-controllable aqueous lubricating liquid and application. The viscosity-controllable aqueous lubricating liquid consists of triethanolamine borate, triethanolamine oleate, triethanolamine sebacic acid, an alcohol viscosifier, an organic silicon defoaming agent and water. The viscosity range is from 0.9 Pa.s to 8 Pa.s. The main component of the water-based lubricating liquid is water, so excellent characteristic, such as fire resistance, of the water and high specific heat are preserved; each component of the aqueous lubricating liquid has low price, no toxicity and high degradability and meets the requirements of environmentally-friendly lubricants; tests show that the aqueous lubricating liquid has high rust resistance; an anti-rusting agent component ofthe aqueous lubricating liquid comprises a polar group with a large adsorption force, so the aqueous lubricating liquid has anti-friction and anti-wear effects on a friction pair and prolongs the service life of equipment; and the viscosity of the lubricating liquid can be adjusted by changing the viscosifier content according to specific engineering requirements, so that the higher rigidity, bearing capacity and heat stability of a processing equipment main shaft and a hydrostatic guideway system are guaranteed.

Description

technical field [0001] The invention relates to a lubricating fluid applied to the main shaft and static pressure guide rail system of mechanical equipment, mainly used for the lubrication of sliding bearings supporting the main shaft and static pressure guide rails supporting moving parts, and provides a viscosity-controllable water-based lubrication liquids and applications. Background technique [0002] Bearings are an important part of rotary processing equipment. The rotation accuracy of the spindle system, shafting stiffness, speed, load capacity, and bearing life directly determine the processing accuracy, work efficiency, maintenance cycle and performance of the final product; the static pressure guide rail is Put pressure oil or compressed air between the two relative moving guide rail surfaces to make the moving parts float, so as to ensure that the two guide rail surfaces are in a state of liquid or gas friction. Fluid sliding bearings or hydrostatic guide rails ...
