Improved antioxidation lubricating oil additive

Abstract

The invention relates to an improved antioxidation lubricating oil additive, which is prepared from the following raw materials by weight: 2-6 parts of calcium hydroxide, 0.3-0.5 part of calcium chloride, 2-6 parts of magnesium alkylbenzene sulfonate, 3-4 parts of paraffin, 20-40 parts of methyl acrylate, 4-12 parts of sulfurized calcium alkyl phenate, 5-6 parts of pentaerythritol, 3-7 parts of calcium alkylbenzene sulfonate, 12-18 parts of T206, 8-13 parts of glyceride acrylate, 7-21 parts of methyl acrylate, 4-8 parts of bis-salicylidene diaminopropane, 3-6 parts of polyisobutylene succinic anhydride, 0.8-1.6 parts of triphenylphosphorothioate, 1-2 parts of a detergent, 0.5-1 part of an antirust agent, 2-6 parts of a viscosity index improver, and 0.8-1.2 parts of an antioxidant. The improved antioxidation lubricating oil additive provided by the invention is conducive to clearing metal powder deposited on friction surfaces and other deposits, has excellent anti-oxidation effects and rustproof and anti-corrosion functions, improves the effect and quality of lubricating oil, and has good protection effect to machines.

Description

technical field [0001] The present invention relates to an improved antioxidant lubricating oil additive. Background technique [0002] Lubricating oil quality is inseparable from additive products. Additives are the main way to improve lubricating oil quality and expand lubricating oil varieties, and also an important means to improve lubricating oil performance, save energy and reduce environmental pollution. Lubricating oil additives have a great influence on the quality of lubricating oil. For example, engines that use fuel oil, kerosene, gasoline, natural gas or artificial gas, liquefied gas, etc. as fuel must use lubricants (such as paraffin-based lubricating oil) to lubricate their Moving parts. The purpose of adding anti-oxidation and anti-corrosion additives to oil is to inhibit the oxidation process of oil, passivate the catalytic effect of metal on oxidation, and prolong the use of oil and protect the machine. However, lubricating oil additives currently on the ...

Problems solved by technology

However, lubricating oil additives currently on the market are generally compound products of a single additive, which is unstable in nature, easily reduces the use effect of lubricating oil, and cannot play the role of prolonging the service life of oil products, and needs to be further improved.
