Abstract

The invention belongs to the field of chemical engineering, particularly relates to an isostearic acid composite metal salt clearing agent, and further discloses a preparation method of the isostearic acid composite metal salt clearing agent. The isostearic acid composite metal salt clearing agent is prepared from, by weight, 0.5-2 parts of isostearic acid, 1.5-3 parts of pentaerythrityl tetraethylhexanoate base oil, 0.5-3 parts of calcium oxide, 0.5-3 parts of magnesium oxide, 10-30 parts of solvent, 0.2-1 part of methyl alcohol, 1-8 parts of water and 0.5-4 parts of carbon dioxide. The composite calcium / magnesium salt clearing agent is obtained by fine screening the raw material and ratio of the product with calcium oxide and magnesium oxide as the alkali raw materials; compared with a simplex magnesium salt clearing agent in the prior art, the clearing agent has the advantages of a calcium salt clearing agent and a magnesium salt clearing agent at the same time; the alkali value of the product is further increased, the acid neutralization capacity is higher, and meanwhile the product is better in oil solubility.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular to an isostearic acid composite metal salt detergent, and further discloses a preparation method thereof. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of 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. However, during the use of engine lubricating oil, due to factors such as harsh operating conditions, high-temperature oxidation, and the inhalation of nitrogen oxides and sulfur dioxide acid gases from the outside, the lubricating oil is prone to oxidative degradation and a certain amount of acid corrosion. Substances, such as sulfuric acid, nitric acid, acid sludge, etc., will reduce the lubricating effect of lubricating oil and aggravate the corrosion of equipment. Therefor...
