A formula of a cooling lubricating fluid used for machine tools

Abstract

The invention discloses a formula of cooling lubricating fluid for machine tools. This lubricating fluid is composed of wood pulp tall oil soap, water, diesel oil and non-ionic surfactant. Its composition weight percentage is: wood pulp tall oil soap dry powder or ointment is 20-30, water is 60-70, diesel oil is 10-20, and nonionic surfactant is 2-5. The lubricating fluid has good lubricating performance, low cost and simple processing conditions.

Description

technical field [0001] The invention relates to the field of lubricating fluid, in particular to a formula of cooling lubricating fluid for machine tools. Background technique [0002] There are dozens of varieties of existing lubricating fluids, and saponified oil and CS-3 emulsified oil are commonly used. Saponified oil is processed in a reaction pot using fatty acid, engine oil, a small amount of diesel oil, water and oil essence. Its disadvantage is that it needs to consume a large amount of vegetable oil and other heavy industrial raw materials, so the cost is very high. In addition, it does not have The ability to resist calcium and magnesium; CS-3 emulsified oil is made by stirring rosin, sodium hydroxide, water and diesel oil in a reaction pot and at a certain temperature. The advantage is that the cost is reduced because diesel oil is used instead of vegetable oil. Moreover, the lubricating performance is equivalent to that of saponified oil, but due to the consump...

Saponified oil is processed in a reaction pot using fatty acid, engine oil, a small amount of diesel oil, water and oil essence. Its disadvantage is that it needs to consume a large amount of vegetable oil and other heavy industrial raw materials, so the cost is very high. In addition, it does not have The ability to resist calcium and magnesium; CS-3 emulsified oil is made by stirring rosin, sodium hydroxide, water and diesel oil in a reaction pot and at a certain temperature. The advantage is that the cost is reduced because diesel oil is used instead of vegetable oil. Moreover, the lubricating performance is equivalent to that of saponified oil, but due to the consumption of a large amount of rosin, diesel oil and sodium hydroxide, the cost is still high, and its processing is limited by technological conditions, so it is difficult to popularize and use it under field conditions.
