Problems solved by technology

The lubricant uses chlorinated paraffin as the extreme pressure agent, which is easy to cause corrosion to the metal, and the anionic oily agent is easy to generate copper soap, which makes the surface of the steel wire unclean during the wire drawing process, thus affecting subsequent processing

preparation example Construction

[0028] The preparation method of the lubricant is as follows: dissolve the emulsifier, pH regulator, co-solvent, antirust agent, complexing agent, bactericide, and defoamer in the formula amount into the water of the formula amount and stir vigorously to mix evenly, and then add the formula A certain amount of oily agent and extreme pressure antiwear agent are heated to 50-80°C, vigorously stirred and mixed evenly to obtain the lubricant.

[0029] The use method of the lubricant is as follows: the lubricant is diluted with water to 5-10 wt%, and then added into a bath for wet drawing processing of steel cords of automobile radial tires.

Abstract

The invention relates to automobile radial tire steel cord wet-pulling lubricating agent, comprising the following components in percent by weight: 13-30% of oiliness solvent, 1-8% of extreme-pressure antiwear agent, 0.5-5% of emulsifier, 3-10% of pH regulator, 2-7% of cosolvent, 3-14% of antirusting agent, 1.1-4% of complexing agent, 0.1-5% of bactericide, 0.1-2% of defoaming agent and balance of water, wherein the oiliness solvent is a mixture of triethanolamine oleate soap, triethanolamine oleate ester, oleic diethanolamide and castor oil; and the extreme-pressure antiwear agent is a mixture of tri-n-butyl phosphate and zinc dialkyl dithiophosphates. The lubricating agent has good extreme-pressure antiwear performance, and service life of a mould can be effectively prolonged; and all the components of the lubricating agent can be effectively biologically degraded, thus the lubricating agent is environmentally friendly.

Description

technical field [0001] The invention belongs to the field of fine chemicals, in particular to a steel cord wet drawing lubricant and a preparation method thereof. technical background [0002] The rapid development of radial tires in the automotive industry has led to a sharp increase in the demand for its main frame material, steel cord. In the production process of steel cord, the drawing process of steel wire is to plate brass first and then draw. The core material of the drawing die is mostly made of tungsten carbide alloy. The bottom is also badly worn. To make the steel wire draw smoothly, a lubricant must be added between the steel wire and the mold core. Lubricants are divided into solid lubricants (drawing powder), oil-based lubricants (drawing oil) and water-based lubricants (wet drawing lubricants). The main component of drawing powder is soap powder, which is cheap, but the lubricating effect is poor, and the cooling effect is not good, and it is easy to form ...
