Embodiment 1

[0029] The modified nano-Cu-TiO provided in this example 2 The preparation methods include:

[0030] Under the condition of ice bath at 0°C-5°C, slowly add titanium tetrachloride dropwise to dilute hydrochloric acid with a concentration of 3mol / L until a yellow-green solution is formed, add 5 volume multiples of deionized water to dilute, and stir slowly until A colorless and transparent solution is generated;

[0031] The above colorless and transparent solution was heated in a constant temperature water bath at 75°C and stirred for 3 hours to obtain a white precipitate;

[0032] The above white precipitate was washed three times with distilled water and absolute ethanol, and dried at 90 °C for 24 h to obtain white nano-TiO 2 Powder;

[0033] Nano TiO 2 The powder is added to the solution containing copper chloride, HCHO, EDTA-4Na and C 5 h 5 In the plating solution of N, stir evenly to obtain nano-TiO 2 Mixed solution, wherein the temperature of the plating solution i...

Abstract

The invention provides lubricating type anti-rust oil special for a bearing bush.The lubricating type anti-rust oil comprises lubricating oil base oil, p-hydroxybenzoic aldehyde, tung oil, diazolidinyl urea, allyl polyethylene glycol 2-3, polyethylene glycol, dithio-borate, salicylate, an anticorrosion additive and a coalescing agent, wherein the lubricating oil base oil contains spherical modified nanometer Cu-TiO2.The lubricating oil base oil contains the spherical modified nanometer Cu-TiO2 component, and copper nanoparticles are loaded on the surface of spherical nanometer TiO2 powder, so that a damaged part is effectively filled, and in-situ remediation is achieved on the damaged surface.Meanwhile, the spherical modified nanometer Cu-TiO2 component enables the nanoparticles between friction antithesis faces to be flattened under heavy loads and high temperature to form a sliding system, and therefore friction and abrasion are lowered more easily.It can be seen that the lubricating type anti-rust oil special for the bearing bush has the good anti-rust effect, and the stable and good lubricating effect can also meet the high using requirement for the bearing bush.

Description

technical field [0001] The invention relates to the technical field of bearing pads, in particular to a special lubricating antirust oil for bearing pads. Background technique [0002] The bearing shell is the contact part of the sliding bearing and the journal. It is in the shape of a tile-like semi-cylindrical surface and is very smooth. It is generally made of wear-resistant materials such as bronze and anti-friction alloy. Similar to other metal or alloy products, during the storage and transportation of the bearing pad, water molecules, oxygen molecules, sodium chloride, acid and alkali in the air are easily adsorbed on the surface of the bearing pad, and have physical and chemical reactions with the bearing pad, making the bearing pad Suffer different degrees of corrosion, especially in the rainy season, the high air humidity is likely to cause serious corrosion of the bearing bush, which not only affects the normal use of the bearing bush, but also brings serious econ...
