Problems solved by technology

Antimony is one of the important elements used to strengthen the matrix. It is only partially dissolved in lead and can be used for both solid solution strengthening and aging strengthening. However, if the content is too high, the toughness and corrosion resistance of the lead alloy will be reduced. Bad

Abstract

The invention relates to a cold-rolling lubricant for lead and lead alloy foils, which uses 5# total loss system oil as base oil matched with multiple compounded additives. The lubricant comprises an antiwear additive, an oily agent, an antioxidant, an antifoam agent, a demulsifying compound, a metal passivator and the like. The base oil has the advantages of short carbon chains, low aromatic hydrocarbon content, low sulfur content, low viscosity, high heat capacity and strong cooling and cleaning power; the lubricant can enhance the technical lubricating property, increase the oil film strength in the deformation range and lower the friction factor; and the lubricant has the advantages of stable composition and performance, no corrosion for metals and equipment, no toxicity and no irritating smell.

Description

technical field [0001] The invention belongs to the field of lubricant for cold rolling of lead and its alloy foil. Background technique [0002] Lead is a bluish, silvery-white heavy metal that is toxic and a malleable main group metal. Density 11.3437g / cm 3 , hardness 1.5, melting point 327.502 ° C, boiling point 1740 ° C, soft texture, low tensile strength. Lead without an oxide layer is bright in color, high in density, very low in hardness, and highly extensible. An important use of metallic lead is to make batteries. Its electrical conductivity is relatively low and its corrosion resistance is high, so it is often used as a container for highly corrosive substances such as sulfuric acid. Adding a small amount of antimony or other metals can further improve its corrosion resistance. The tensile strength of lead alloy is 3~7kgf / mm 2 , much lower than most metal alloys. Antimony is one of the important elements used to strengthen the matrix. It is only partially di...
