[0002] Aluminum alloy materials have become the most widely used non-ferrous metal structural materials in the industry due to their excellent performance. However, during the cutting process of aluminum alloys, workpiece corrosion, discoloration, short tool life, and substandard surface finish are prone to occur. Large residues on the surface of the workpiece, prone to problems such as built-up edge, especially the die-casting aluminum alloy containing silicon and copper, there are a large number of micropores distributed on the non-processed surface, the structure is relatively loose, the corrosion resistance is poor, and it is prone to discoloration or electrochemical corrosion

Abstract
The invention discloses semi-synthesis cutting liquid for low-phosphorus chlorine-free non-formaldehyde aluminum alloy cutting processing and belongs to the technical field of metal processing mediums. The semi-synthesis cutting liquid is prepared from the following components in percentage by weight: naphthene base crude oil, an extreme pressure lubricant, an oily lubricant, an emulsifier, organic alcohol amine combination, a silicon-containing aluminum corrosion inhibitor, an anti-rust agent, a copper corrosion inhibitor, a sterilizing agent, a coupling agent, water and a defoaming agent. Due to adoption of the combination of the extreme lubricant and the oily lubricant, the lubricating ability of the cutting liquid and the surface smoothness of a workpiece are improved; due to adoptionof the alcohol amine combination, the alkali retaining ability and the pH stability of the cutting liquid and the stability of microorganisms are improved; due to adoption of the silicon-containing aluminum corrosion inhibitor, the aluminum corrosion inhibition performance of the aluminum alloy cutting liquid is realized; due to adoption of a bacteriostatic system, introduction of phosphorus is reduced, the alcohol ether bacteriostatic component is increased and the service life of the cutting liquid is prolonged; and due to adoption of the non-formaldehyde release type sterilizing agent, theadverse influence on a human body and the environment by the cutting liquid is reduced.
