Drawing oil containing lecithin

Abstract

The invention relates to a drawing oil, specifically to a drawing oil containing lecithin. The drawing oil is prepared from the following raw materials by weight: 80 to 100 parts of coconut oil, 60 to 80 parts of fluorinated silicone oil, 0.01 to 0.02 part of polyvinylpyrrolidone, 10 to 12 parts of isooctyl oleate, 8 to 10 parts of lecithin, 0.2 to 0.3 part of gallic acid, 2 to 3 parts of glycerin, 0.5 to 0.6 part of zinc naphthenate, 0.4 to 0.5 part of nonylphenol ethoxylate, 0.5 to 1 part of chlorinated paraffin and 2 to 3 parts of an auxiliary agent. According to the invention, temperature-resistant fluorinated silicone oil is added into base oil of the drawing oil, nontoxic and innocuous lecithin is used as an emulsifier, so a good emulsification effect is obtained; through combination of fluorinated silicone oil, lecithin and other additives, the drawing oil provided by the invention has excellent extreme pressure wear resistance and high temperature lubrication performance, does not corrode wire rods in use, has appropriate viscosity, is easy to clean and is applicable to wire drawing and drawing process for a variety of metal materials.

Description

technical field [0001] The invention relates to a drawing oil, in particular to a drawing oil containing lecithin and a preparation process thereof. Background technique [0002] Drawing oil is a kind of important industrial additives. It is used as high-efficiency lubricating oil in the process of metal wire drawing and drawing. It has the functions of lubrication, cleaning, cooling, and antirust. Yield rate, reduce production loss. The existing drawing oils are mainly divided into oily drawing oils and water-based drawing oils. These two types of drawing oils have their own advantages and disadvantages in actual use. For example, oily drawing oils have poor heat dissipation performance, difficult cleaning and chip removal, and difficult degradation of waste liquid. Although water-based wire drawing oil has better heat dissipation performance than oil-based wire drawing oil, its lubricating effect is not satisfactory, and it is difficult to meet the requirements of wire dr...

The existing drawing oils are mainly divided into oily drawing oils and water-based drawing oils. These two types of drawing oils have their own advantages and disadvantages in actual use. For example, oily drawing oils have poor heat dissipation performance, difficult cleaning and chip removal, and difficult degradation of waste liquid. Although water-based wire drawing oil has better heat dissipation performance than oil-based wire drawing oil, its lubricating effect is not satisfactory, and it is difficult to meet the requirements of wire drawing and drawing processes for various metal wires. Therefore, in order to improve the machining level of enterprises and reduce production costs, it is necessary Improve the formula and process of drawing oil to achieve good performance
