Abstract

The invention discloses an oil composition for a sewing machine. The sewing machine oil composition is prepared from the following components in percentage by mass: 0.15 to 0.3 weight percent of alkylated phenyl phosphorothioate, 0.05 to 0.1 weight percent of dialkyl dithiocarbamate, 0.1 to 0.2 weight percent of ionic liquid, 0.2 to 0.3 weight percent of food-grade antioxidant, 0.05 to 0.1 weight percent of hindered amine light stabilizer, 0.02 to 0.04 weight percent of antirust agent, 0.02 to 0.05 weight percent of anti-foaming agent, 0.01 to 0.03 weight percent of demulsifier and the balance of mineral base oil. According to the lubricating oil, additives such as a double-anti-wear system, the food-grade antioxidant, the choline lipoic acid ionic liquid and the light stabilizer are compounded, so that the lubricating oil has good light stability and anti-wear performance and excellent antioxidant performance, is green and environment-friendly, has excellent anti-rust property, demulsification property and the like, and can meet the lubricating requirement of high-speed sewing machine equipment.

Description

technical field [0001] The invention relates to a lubricating oil composition, especially a lubricating oil composition suitable for the lubricating system of a sewing machine. Background technique [0002] The working principle of the sewing machine is that the needle bar reciprocates up and down, and the belt drives the needle to guide the suture through the cloth or leather to complete the sewing process. Sewing machine oil needs to effectively protect transmission components such as bearings, gears, cams, and worm gears. At the same time, it is required to have excellent oxidation stability to reduce or avoid the generation of sludge; the viscosity of sludge is suitable; it has stronger light color stability and will not pollute Discoloration of fabrics; colorless, odorless, does not corrode fiber textiles, etc. [0003] Sewing machine oil is a colorless translucent oily liquid, odorless and tasteless, and has good stability against light, heat, acid, etc. The lubricati...
