Abstract

The invention discloses aluminum alloy semisynthesis cutting liquid and a preparation method thereof. The aluminum alloy semisynthesis cutting liquid is composed by weight of 12%-20% of mineral oil, 9%-15% of surfactant, 8%-12% of antirust agent, 1%-2% of aluminum corrosion inhibitor, 3%-7% of lubricant, 8%-12% of extreme pressure agent, 0.5%-1% of defoamer, 0.5%-1% of fungicide and the balance, water. The preparation method includes sequentially adding the surfactant, the antirust agent, the aluminum corrosion inhibitor, the lubricant, the extreme pressure agent, the defoamer, the fungicide and the water into the mineral oil and evenly stirring and mixing the mixture to obtain the aluminum alloy semisynthesis. The aluminum alloy semisynthesis cutting liquid has excellent performance on aluminum corrosion inhibition performance, corrosion resistance, lubricant performance, anti-rust performance, defoaming performance, use period and the like.

Description

technical field [0001] The invention relates to an aluminum alloy semi-synthetic cutting fluid and a preparation method thereof. Background technique [0002] Aluminum alloy is one of the most widely used non-ferrous metals. It has low density, light weight, high specific strength, good electrical and thermal conductivity and good corrosion resistance. Aluminum alloy has strong chemical activity, soft texture and strong viscosity, and there are many problems in production and processing. The most common problems are cutting oil sticking to the knife and black spots caused by oxidation and discoloration of workpieces during cutting fluid processing. [0003] At present, the domestic water-soluble cutting fluid used in aluminum alloy processing in the machining industry is mainly emulsified oil. The problems with emulsified oil processing are short service life, poor visibility during processing, easy to be corrupted and smelly, and waste liquid is relatively high. Difficult ...
