Problems solved by technology

[0002] In order to increase the anti-friction and anti-wear effect of lubricating oil, a small amount of lubricating oil additives are usually added to lubricating oil. Traditional lubricating oil additives are high-sulfur, high-phosphorus or chlorine-containing anti-wear agents. Corrosive and selective, and not environmentally friendly

Abstract

The invention discloses an aliphatic amine ester boride lubricating oil additive and a preparation method thereof. The method comprises the following steps: putting methyl oleate and triethanolamine in a container, reacting under the conditions of the temperature of 90 DEG C and the pressure of 80mmHg for 4-5 hours, adding oleic acid and reacting, and obtaining oleamide; mixing the oleamide and phosphorus pentasulfide and dodecanol, continuously cyclically introducing ammonia gas at high pressure, reacting at the temperature of 170-180 DEG C for 4-5 hours, and obtaining an aliphatic amine ester mixture; mixing aliphatic amine ester and boric acid, reacting under the conditions of the temperature of 100 DEG C and the pressure of 230mmHg for 4-5 hours, reducing the pressure to 30mmHg, and reacting; and reducing the temperature, filtering and obtaining the aliphatic amine ester boride lubricating oil additive. A novel low-sulfur low-phosphorus high-efficiency and boron nitride structure-containing aliphatic amine ester boride lubricating oil additive is prepared through continuous cyclic introduction of ammonia gas in a three-step reaction and a two-step pressure reduction method, and the prepared product has excellent wear resistance, antifriction property and oxidation resistance, the production method is simple, the cost is low, and the product structure is stable.

Description

technical field [0001] The invention relates to a lubricating oil additive and a preparation method thereof, in particular to a borated fatty amine ester lubricating oil additive and a preparation method thereof. Background technique [0002] In order to increase the anti-friction and anti-wear effect of lubricating oil, a small amount of lubricating oil additives are usually added to lubricating oil. Traditional lubricating oil additives are high-sulfur, high-phosphorus or chlorine-containing anti-wear agents. Corrosive and selective, and not environmentally friendly. As for the mechanism of new anti-wear and anti-friction, as early as the mid-1960s, people began to use different experimental instruments and analysis methods to study. Borated fatty amine esters containing B, S, P, and N in the molecular structure, when used in lubricating oils, can greatly improve the anti-wear and anti-friction functions of oil products, ash-free, increase lubricating and dispersing prope...
