Abstract

The invention discloses a composition of a white alloy cold extrusion processing lubricant. HVIH 14-base oil is adopted as base oil which is compounded with multiple composite additives, including an antioxidant, a metal deactivating agent, an oiliness agent, a friction improver, an extreme pressure agent, a tackifier, an anti-rusting agent, an antioxidant anti-wearing agent, a cooling accelerant, an anti-wearing agent and the like. The lubricant composition disclosed by the invention is good in lubrication, cooling property, extreme pressure loading anti-wearing property, cleaning ability, oxidation and corrosion resistance, adhesion, oil film strength and oil film thickness stability.

Description

technical field [0001] The invention belongs to the field of metal processing lubricants, in particular to a composition of white metal cold extrusion processing lubricants 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 structural characteristics of Babbitt alloy are that hard phase particles are evenly ...
