Abstract

The invention relates to a cold rolling lubricating agent for tin and tin alloy foils. No. 5 industrial white oil is adopted as base oil, a variety of compound additives are used for matching, and the compound additives comprise an anti-wear agent, an oiliness agent, an antioxidant, a defoaming agent, a demulsifying agent and a friction modifier. The lubricating agent has the advantages of short carbon chain, low aromatics, low sulfur content, lower viscosity, large heat capacity, strong cooling, cleaning and dispersion capacities, stable composition and performances, no corrosion against metals and equipment, no toxicity and no irritating odor and can be used for simultaneously improving the process lubrication performance, increasing the strength of an oil film in a deformation area and reducing the friction coefficient.

Description

technical field [0001] The invention belongs to the field of lubricant for cold rolling of tin and its alloy foil. Background technique [0002] Tin, metal element, a kind of low-melting metal element with bluish white luster, tin is a silver-white soft metal with a specific gravity of 7.3g / cm 3 , the melting point is low, only 232 ℃, and it will melt into a mercury-like liquid when put into a briquette furnace. Tin is soft enough to cut through it with a knife. Tin is chemically stable and is not easily oxidized at room temperature; therefore, it often retains its silvery luster. Tin is non-toxic, has a low melting point, and has strong plasticity, but its ductility is very poor, and it will break when pulled, and cannot be drawn into filaments. Tin can have various surface treatment processes and can be made into various styles of products. It is still an indispensable key rare metal in modern industry. Machinery, food packaging and other industries. [0003] In the t...
