Embodiment 1

[0012] A lubricating oil dispersant, comprising the following components: 12 kg of succinimide, 3 kg of polyalphaolefin, 3 kg of phosphorus pentasulfide, 4 kg of dialkyl dianiline, 6 kg of isooctyl phosphate, calcium hydroxide 3 kg, 8 kg of pentaerythritol, 7 kg of borated polyisobutenyl succinimide, 3 kg of trimethylolpropane, 6 kg of hydrogen-containing silicone oil, 5 kg of phosphobisoctyl zinc salt, 4 kg of chlorinated paraffin, naphthene acid 6 kg, sodium sulfite 4 kg, sodium dodecylbenzenesulfonate 4 kg and triethanolamine 5 kg.

[0013] The lubricating oil dispersant provided by the invention has good heat resistance, has a strong solubilizing effect on the initial oxidation product of the lubricating oil liquid state, and has a good peptizing and dispersing effect on solid particles such as carbon deposits and soot. At the same time, it reduces the influence on the low-temperature viscosity of lubricating oil. The low-temperature viscosity is small, and it can effectiv...

Abstract

The invention discloses a lubricating oil dispersing agent comprising the following components in parts by mass: 12-14 parts of succinimide, 3-5 parts of polyalphaolefin, 3-5 parts of phosphorus pentasulfide, 4-6 parts of dialkyl diphenylamine, 6-8 parts of isooctyl phosphate, 3-5 parts of calcium hydroxide, 8-10 parts of pentaerythritol, 7-9 parts of boronized polyisobutenyl succinimide, 3-5 parts of trimethylolpropane, 6-8 parts of hydrogen-containing silicon oil, 5-7 parts of zinc dialkyl dithiophosphate, 4-6 parts of chlorinated paraffin, 6-8 parts of naphthenic acid, 4-6 parts of sodium sulfite, 4-6 parts of sodium dodecyl benzene sulfonate and 5-7 parts of triethanolamine. The lubricating oil dispersing agent has the advantages that jelly and carbon deposits on parts can be effectively cleaned to reduce accumulation, and meanwhile, the lubricating oil dispersing agent has good cleaning and antioxidant effects.

Description

technical field [0001] The invention relates to the technical field of chemicals, in particular to a lubricating oil dispersant. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil is composed of base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil and endow some new properties. An important component of oil. At present, people widely use the method of adding dispersant to lubricating oil. The function of dispersant is to disperse the precursors of sludge, varnish and carbon deposits in the oil, prevent them from forming sludge, varnish and carbon deposits, and prolong oil change ...
