Anti-shake vertical guide rail oil of CNC machining center and preparation method of anti-shake vertical guide rail oil

Abstract

The invention provides anti-shake vertical guide rail oil of a CNC machining center and a preparation method of the anti-shake vertical guide rail oil, and relates to the technical field of CNC machining center guide rail lubrication.The guide rail oil is prepared from, by weight, 22%-30% of first base oil, 60%-88% of second base oil, 0.5%-0.8% of an antioxidant, 0.1%-0.2% of an anti-wear reagent at extreme pressure, 0.05%-0.06% of a passivating agent, 0.005%-0.02% of a defoaming agent and 0.1%-0.4% of an anti-rust agent, 1-2% of a high-molecular polyisobutene oil solution, 2-4% of high-viscosity complex ester and 0.5-0.6% of a pour point depressant. According to the anti-shaking vertical guide rail oil, the 150SN base oil and the 500SN base oil are mixed, the viscosity can be effectively adjusted, the shaking amplitude of a guide rail can be relieved through the arranged extreme pressure anti-wear agent, the pour point of the anti-shaking vertical guide rail oil can be effectively reduced through the pour point depressant, the sintering load can be effectively improved through the high-viscosity complex ester, and the service life of the anti-shaking vertical guide rail oil is prolonged. And finally, by means of the mixed antirust agent, the rusting speed of the guide rail can be reduced, the liquid-phase rusting performance is enhanced, and actual use is facilitated.

Description

technical field [0001] The invention relates to the technical field of guide rail lubrication for CNC machining centers, in particular to an anti-shake vertical guide rail oil for CNC machining centers and a preparation method thereof. Background technique [0002] Computer numerical control machine tool (abbreviated as CNC) is an automatic machine tool equipped with a program control system, which can logically process and decode programs with control codes or other symbolic instructions, so that the machine tool moves and Processing parts, while the CNC machining center often needs to lubricate the vertical guide rail with guide rail oil when it is working. [0003] Chinese Patent No. CN111349507A discloses a lubricant for CNC machine tools and a preparation method thereof, which mainly consists of the following raw materials in weight percentage: 5-15% of oxygen-containing organic compounds, 2-8% of oxidized polyethylene, 2-8% of acrylic acid, vulcanized 1-3% of lard, 1-...

[0003] Chinese Patent No. CN111349507A discloses a lubricant for CNC machine tools and a preparation method thereof, which mainly consists of the following raw materials in weight percentage: 5-15% of oxygen-containing organic compounds, 2-8% of oxidized polyethylene, 2-8% of acrylic acid, vulcanized 1-3% of lard, 1-5% of extrusion anti-wear agent, 1-5% of antirust agent, 1-6% of dispersant, 0.001-0.005% of nano particle composition, and the balance is base oil for lubricating oil, Although this kind of CNC machine tool lubricant has positive effects such as accelerating the lubrication speed, improving wear resistance, improving wetness, good anti-oxidation effect, and prolonging the service life, it cannot overcome the problem of rust on the guide rail of the CNC machining center. Therefore, it needs to be carried out. Improve

[0004] Chinese Patent No. CN113801718A discloses a lubricant for CNC machine tools. The lubricant oil for CNC machine tools is made of the following raw material ratios by weight: 12-16 parts of sunflower oil, 15-18 parts of corn oil , 11-17 parts of palm oil, 16-40 parts of antioxidant, 7-14 parts of nano-alumina, 12-15 parts of boric acid, 3-6 parts of rust inhibitor, 8-12 parts of dispersant, this kind of lubricating oil for CNC machine tools Although it has good anti-oxidation and anti-corrosion effects, it cannot solve the problem of vibration of vertical guide rails in CNC machining centers, and needs targeted improvement
