Abstract

The invention provides a cast stone containing lubricating oil and a preparation method of the cast stone. The cast stone containing lubricating oil is prepared from the following ingredients: mineralbase oil, a cast stone, modified zirconite, dimethyl succinate, nonylphenol polyoxyethylene ether, polyvinyl alcohol, methyl carbamate, borate, triethylamine oleate, a friction additive and a surfactant. The prepared lubricating oil is excellent in abrasion resistance, rust resistance, heat stability, anti-foaming property, sealing adaptability and is higher in cleanliness, the requirement of high-strength mechanical equipment on the lubricating oil is met, the adhesive force of the lubricating oil is stronger, the oil is not easily lost rapidly, the preparation method is simple, the industrial production of the lubricating oil is convenient, the cost is low, the defect of poor oxidation stability of the traditional lubricating oil is overcome, and the stability is better.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil production, and in particular relates to a lubricating oil containing cast stone and a preparation method thereof. Background technique [0002] Lubricating oil refers to the liquid lubricant used in various types of automobile transmission, mechanical equipment, and precision instruments to reduce friction and protect machinery and processed parts. It is mainly used to reduce friction between the surfaces of moving parts, and at the same time has cooling, Sealing, anti-corrosion, anti-rust, insulation, power transmission, cleaning impurities, etc. Lubricating oil is a technology-intensive product, which is a mixture of complex hydrocarbons, and its real performance is the combined effect of complex physical or chemical changes. The basic properties of lubricating oil include general physical and chemical properties, special physical and chemical properties and simulated bench tests. Eac...
