Embodiment Construction

[0007] The technical solution adopted in this specific embodiment is: a potassium borate amide urea antiwear agent with good hydrolysis resistance and compatibility is composed of the following raw materials: potassium hydroxide, boric acid, ethylenediamine, isocyanate, octadecylamine; Potassium+boric acid+ethylenediamine+isocyanate+octadecylamine mol ratio is 1: 2: 1: 1: 1; Its preparation method comprises the following steps: one, make the potassium amide urea antiwear agent of borate of 100kg, first mix 27.6 Add 500kg of lubricating base oil 500SN into the reactor, dissolve 6kg of ethylenediamine and 27kg of octadecylamine, add 15.8kg of isocyanate to react into a paste, add 240kg of boric acid in turn, then add 112kg of potassium hydroxide, and react until Potassium borate amide urea was obtained at 220°C as a medium; 2. Potassium borate amide urea was mixed with potassium tetraborate to obtain a finished potassium borate amide urea antiwear agent.

Abstract

The invention provides a potassium borate amide urea anti-wear agent with hydrolysis resistance and good compatibility and relates to the technical field of anti-wear agent manufacturing technologies.The potassium borate amide urea anti-wear agent is prepared from the following raw materials: potassium hydroxide, boric acid, ethylenediamine, isocyanate and octadecylamine, wherein the mol ratio ofthe potassium hydroxide to the boric acid to the ethylenediamine to the isocyanate to the octadecylamine is 1 to 2 to 1 to 1 to 1; the preparation method comprises the following steps: 1, producing 100 kg of the potassium borate amide urea anti-wear agent; adding 27.6 kg of lubricating oil basic oil 500SN into a reaction kettle; after dissolving 6 kg of the ethylenediamine and 27 kg of the octadecylamine, adding 15.8 kg of the isocyanate and reacting to generate paste; adding 240 kg of the boric acid and 112 kg of the potassium hydroxide in sequence; reacting to 220 DEG C to obtain potassiumborate amide urea as a medium; 2, mixing the potassium borate amide urea and potassium tetraborate to obtain a potassium borate amide urea anti-wear agent finished product. With the adoption of the technical scheme, the potassium borate amide urea anti-wear agent provided by the invention has the beneficial effects that the potassium borate amide urea anti-wear agent is hydrophobic and oleophylicand has relatively strong hydrolysis resisting performance and good compatibility; a manufacturing process is simple, the production cost is relatively low and the cost performance is high.

Description

technical field [0001] The invention relates to the technical field of antiwear agent production technology, in particular to a potassium borate amide urea antiwear agent with good hydrolysis resistance and compatibility. Background technique [0002] Anti-wear agent is a high-tech engine oil (lubricating oil) additive, processed by various technical means, can reduce engine wear and increase engine power, so it is also called engine maintenance agent or powerful repair agent, which can prolong the service life of engine oil. Longer service life, save fuel, improve power. The existing anti-wear agent has low hydrolysis resistance and low compatibility, and the production process is relatively cumbersome and the production cost is high. Contents of the invention [0003] The object of the present invention is to aim at the defects and deficiencies of the prior art, to provide a kind of anti-hydrolysis and good compatibility potassium amide urea anti-wear agent, it is hydro...
