Cutting oil composition for glass cutting and preparation method thereof

The invention belongs to the technical field of engineering glass deep processing, and particularly relates to a cutting oil composition for glass cutting and a preparation method. Comprising the following components in percentage by weight: 85-95% of mineral oil, 1-5% of an anti-rust cleaning agent, 3-8% of a lubricating dispersant, 0.5-4% of an antioxidant and 0.5-2% of a coloring agent. According to the technical scheme, the mineral oil is innovatively selected as the base oil of the cutting oil for glass cutting, compared with kerosene cutting oil which is widely applied traditionally, the mineral oil has the characteristic of high viscosity, the viscosity value of the mineral oil can be adjusted according to different compounding proportions in the composition, and the viscosity value of the compound cutting oil composition is not lower than 10 mPa.s. The surface tension of the glass in glass fracture expansion is relatively strong in control, and the glass can bear the extrusion of glass stress without
