High-performance calcium-series drawing powder and preparation method thereof

Abstract

The invention discloses high-performance calcium-series drawing powder comprising the following components in percentage by weight: 40-60% of stearic acid, 2-3% of organic molybdenum compound, 1-3% of melamine complex, 1.5-2.5% of organic boron compound, a proper amount of chemical additive and the balance of lime. A preparation method comprises the following steps: melting the stearic acid, then adding the lime, melamine complex, an organic molybdenum compound, an organic boron compound and the proper amount of chemical additive, continuously heating to 150-200 DEG C while stirring continuously, and reacting completely to obtain the high-performance calcium-series drawing powder. The high-performance calcium-series drawing powder is insoluble in water, good in lubricating effect and low in consumption.

Description

technical field [0001] The invention relates to a high-performance calcium-based drawing powder and a preparation method thereof, belonging to the technical field of chemical product processing. Background technique [0002] High-performance calcium-based drawing powder is mainly used for high-carbon steel, such as 70#, 80#, 82B steel, high-strength (tensile strength is generally greater than 1900MPa) steel wire drawing process lubricant, in the production of high-strength, high-carbon steel 1. For steel wires with large wire diameters, high-performance calcium-based drawing powders must be used. Ordinary drawing powders cannot meet the production requirements due to their inability to withstand high temperatures, weak extrusion resistance, and poor adsorption to steel substrates. At present, the high-performance calcium-based drawing powders in the world are mainly German-based, and there is no self-developed high-performance calcium-based drawing powder in China. Content...

Ordinary drawing powders cannot meet the production requirements due to their inability to withstand high temperatures, weak extrusion resistance, and poor adsorption to steel bases.

At present, the high-performance calcium-based drawing powder in the world is mainly German-based, and there is no self-developed high-performance calcium-based drawing powder in China.
