Abstract

A lubricant for extruding lead and lead alloy materials adopts NO.10 industrial white oil as base oil and combines various composite additives. The composite additives comprise an oiliness agent, an anti-wear agent, an anti-foaming agent, an antioxidant and an extreme pressure agent. The lubricant for the extruding lead and the lead alloy materials, provided by the invention, has the properties of low viscosity, high infiltrability and good viscosity-temperature characteristic, and can improve the pulling resistance and crack resistance of punching materials, increase the limit drawing ratio, lower the friction coefficient, improve the punch forming effect, increase surface smoothness, facilitate demoulding and cleaning and reduce extrusion force so as to reduce energy consumption.

Description

technical field [0001] The invention belongs to the field of lubricants for extruding process of non-ferrous metal processing, in particular for extruding lead and lead alloy materials. Background technique [0002] Lead is a bluish, silvery-white heavy metal that is toxic and an extensible main group metal. Melting point 327.5°C, boiling point 1740°C, density 11.34g / cm 3 , hardness 1.5, soft texture, low tensile strength. Lead is prone to rust - oxidize. Lead is often gray because it is easily oxidized by oxygen in the air into gray-black lead oxide in the air, making its silver-white luster gradually dull. An important use of metallic lead is to make batteries. The deformation resistance of lead alloy is small, and the ingot can be made into plates, strips, pipes, rods and wires by rolling, extrusion and other processes without heating, and no intermediate annealing treatment is required. Due to the low shear and creep strength of lead alloys, under certain load and r...
