Abstract

This invention discloses a magnesium board rolling lubricant consisting of additive of 2-10% by weight and base oil of 90-98% by weight; constituents of the additive include C12-C18 alcohol of 40-90%,C12-C18 fatty acid methyl ester of 2-50%, C16-C18 butyl stearate of 2-20%, C12-C16 fatty acid of 1-10%, chemical inhibitor 2, 4, 6, tri-tert-butylphosphine paracresol and metal deactivator hydrotriazole ramification of 0.5-5%; the base oil is narrow fraction kerosene adopting secondary hydrogenation treatment, wherein content of paraffin is 50-80%; hydrocarbon content in the C12 and C13 is 70-80%, and average carbon molecule amount is 12.5-13.5. The lubricant provides a lubricant excellent in performance to coiled rolling of magnesium alloy.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and relates to a metal plastic processing aid, in particular to a lubricant for rolling magnesium strips. Background technique [0002] Magnesium alloy has the advantages of light weight, high specific strength and specific stiffness, good electromagnetic shielding, and easy recycling. It is widely used in aviation, aerospace, transportation, information and other fields, and has become an important engineering structure after steel, aluminum, and copper. Materials have attracted great attention and research and development from developed countries in the world. Since magnesium has only one slip surface, there are few independent slip systems, the plasticity at room temperature is poor, and deformation processing is difficult. The traditional ingot casting-hot rolling-warm rolling method is used to prepare magnesium alloy plates and strips, which has high energy consumption, long production cycle, a...
