Drawing oil containing talcum powder

Abstract

The invention relates to drawing oil, specifically to drawing oil containing talcum powder. The drawing oil is prepared from the following raw materials, by weight, 120-150 parts of cottonseed oil, 35-40 parts of hydrogenated polyisobutene, 4-5 parts of glyceryl trioleate, 0.5-1 part of polydimethylsiloxane, 1-2 parts of zinc dialkyl dithiophosphate, 10-12 parts of monoglyceride stearate, 1-2 parts of talcum powder, 1-2 parts of alkyl imidazoline quaternary ammonium salt, 0.01-0.02 part of a silane coupling agent KH550 and 2-3 parts of an auxiliary agent. According to the drawing oil, hydrogenated polyisobutene is added into cottonseed oil so as to improve temperature resistance and stability of base oil; with the talcum powder which has undergone surface modification treatment, heat stability of the drawing oil is enhanced; with the combination of other additives, the prepared drawing oil has excellent lubricating property and good fluidity and easily forms a film on a metal surface; and the oil film still can exist stably in a high heat state so as to effectively protect metal wires and dies. The drawing oil can be suitable for a wire-drawing technology of various metal materials.

Description

technical field [0001] The invention relates to a drawing oil, in particular to a drawing oil containing talc powder 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...

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
