Problems solved by technology

[0002]Cutting fluid is essential in metal cutting. Emulsified cutting fluid has good lubricating and cooling performance. In the past, metal cutting fluid used in turning, grinding and drilling machines has emulsified Oil (containing aromatic hydrocarbons and alcohol harmful gases) has poor rust resistance, poor permeability, odor, and is easy to deteriorate; transparent cutting fluid has excellent cooling and cleaning properties, and has a long service life. The disadvantage is lubrication and rust resistance Poor, and mostly contain chemical substances that damage human health and pollute the environment, such as patent CN87101044A contains sodium nitrite, sodium pentachloride, etc., seriously pollute the environment and endanger the personal health of operators

Abstract

The invention discloses an antirust transparent cutting fluid and a preparation method thereof. The antirust transparent cutting fluid comprises, by weight, 3-8 parts of triethanolamine, 1-5 parts of polyethylene glycol 2000, 0.2-0.8 parts of trisodium phosphate, 0.2-0.6 parts of polyglyceryl fatty acid ester, 0.5-1 part of sodium hyposulfite, 2-6 parts of glycerin, 1-5 parts of sodium carbonate and 80-90 parts of water. The preparation method comprises the following steps of heating water to a temperature of 60-70 DEG C, adding the above components into the water, carrying out stirring dissolution, and cooling the solution to a room temperature so that the antirust transparent cutting fluid is obtained. The antirust transparent cutting fluid has good antirust performances and anticorrosion performances, can prevent a one-grade gray cast iron single sheet from rusting at a temperature of 35+ / -2 DEG C for more than 72h, and can prevent the laminated sheets from rusting for more than 25h. A corrosion test proves that through the antirust transparent cutting fluid, at a temperature of 55+ / 2 DEG C, cast iron rusts after more than 78h and red copper rusts after more than 20h.

Description

technical field [0001] The invention belongs to the technical field of preparation of mechanical protective fluid, and in particular relates to an antirust transparent cutting fluid and a preparation method thereof. Background technique [0002] Cutting fluid is essential in metal cutting. Emulsified cutting fluid has good lubricating and cooling performance. In the past, metal cutting fluid used in cars, grinding and drilling machines has emulsified oil (containing aromatic hydrocarbons and alcohol harmful gases), which has poor rust resistance. , Poor permeability, odor, easy to deteriorate; transparent cutting fluid has excellent cooling and cleaning properties, long service life, the disadvantage is poor lubrication and rust resistance, and most of them contain chemical substances that damage human health and pollute the environment , Contain sodium nitrite, sodium pentachloride etc. as patent CN87101044A, pollute environment seriously, endanger the personal health of op...
