Abstract

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. The raw material composition of the isostearic acid composite metal salt detergent comprises: 0.5-2 parts by weight of isostearic acid, 1.5-3 parts by weight of pentaerythritol tetracaprylate base oil, 0.5-3 parts by weight of calcium oxide, and 0.5 parts by weight of magnesium oxide. -3 parts by weight, 10-30 parts by weight of solvent, 0.2-1 parts by weight of methanol, 1-8 parts by weight of water, and 0.5-4 parts by weight of carbon dioxide. The isostearic acid composite metal salt detergent of the present invention adopts calcium oxide and magnesium oxide as alkaline raw materials, and by carefully screening the raw materials and proportioning of the product, the composite metal calcium and magnesium salt detergent obtained are compared to The single metal magnesium salt detergent in the prior art has the advantages of both calcium salt and magnesium salt detergents, further improves the alkali value of the product, has stronger acid neutralization ability, and at the same time has better 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...
