Abstract

The invention discloses a Babbitt metal spinning lubricant composition. The lubricant composition uses an MVI 90 BS base oil and boride phosphate composite as base oil and is supplemented with a plurality of complex additives including an oily agent, a friction modifier, an extreme pressure agent, an antiwear agent, an antioxidant, a metal deactivator, an anti-rust agent, an oxidation and corrosion inhibitor, a tackifier and so on. The lubricant composition provided by the invention has advantages of good diffusibility, fluidity, carrying capacity, lubrication performance, cooling performance, rust prevention property and corrosion resistance and easiness in cleaning.

Description

technical field [0001] The invention belongs to the field of metal processing lubricants, in particular to a white metal spinning lubricant composition. Background technique [0002] White metal was named after the invention of American Babbitt, because of its white color, it is also called Babbitt alloy. Including tin-based bearing alloys and lead-based bearing alloys, are widely used. It has anti-friction properties and is the only material suitable for rotating relative to a low-hardness shaft. Compared with other bearing materials, it has better adaptability and press-fit properties. It is widely used in large marine diesel engines, turbines, alternators, and Other mining machinery and large rotating machinery, etc. Its main alloy components are tin, lead, antimony and copper. Antimony, copper, used to increase the strength and hardness of the alloy. [0003] The characteristics of the structure of Babbitt alloy are that the hard phase particles are evenly distribute...
