Production method for non-ferrous metal semi-synthetic working fluid

Abstract

The invention provides a production method for a non-ferrous metal semi-synthetic working fluid, belonging to the field of metal working fluids. The non-ferrous metal semi-synthetic working fluid comprises, by weight, 20 to 56% of water, 5 to 20% of triethanolamine, 1 to 10% of a diaminodimethyl pH stabilizing agent, 1 to 5% of benzotriazol (T706), 1 to 20% of a waterborne antirust agent (T485), 1 to 15% of boric acid, 5 to 10% of a dipropylene glycol methyl ether coupling agent, 2 to 10% of a bactericide BK, 5 to 20% of castor oil fatty acid, 1 to 20% of tall oil fatty acid, 1 to 40% of transformer oil No. 10, 1 to 30% of a nonionic surfactant, 10 to 20% of an anionic surfactant and 10 to 20% of sorbitan methyl oleate. The non-ferrous metal semi-synthetic working fluid prepared by the production method has excellent quality and long service life, is green and environment-friendly and can be extensively applied to processing of non-ferrous metal.

Description

technical field [0001] The invention relates to a metal processing fluid, in particular to a method for preparing a nonferrous metal semi-synthetic processing fluid. Background technique [0002] In the process of metal processing, people generally use oil-based machining fluid or emulsion. Oil-based machining fluid has a good lubricating effect. The disadvantage is that oil-based machining fluid has poor cleaning performance, is difficult to clean, and is easy to leave Spots, difficult to degrade, and very serious environmental pollution; the emulsion has good cooling properties, but the disadvantage is that the emulsion needs to be stable in a high pH range, and it is not easy to prevent mildew and antibacterial, so the emulsion is prone to corruption and deterioration. Odor, the emulsion is easy to drift and the oil is unstable, which shortens the processing cycle of the processing fluid. Contents of the invention [0003] The purpose of the present invention is to ove...
