Problems solved by technology

However, there is a certain performance competition between the lubricating performance of the machining fluid and the rust and corrosion inhibition performance of the metal, and it is difficult to achieve an excellent comprehensive effect at the same time. During the use of the machining fluid, the Ca 2+ , Mg 2+ The enrichment will lead to an increase in the hardness of the machining fluid, which will further aggravate the attenuation of the anti-rust and corrosion inhibition performance of the aluminum alloy machining fluid
[0007] Most of the existing semi-synthetic aluminum alloy processing fluids cannot meet the synergistic effect of high hard water rust resistance and lubricity, and are prone to poor performance in some aspects in actual use, especially in the processing of aluminum alloys with high Mg content. Mg 2+ The accumulation of the processing fluid increases the hardness, which easily leads to the obvious attenuation of corrosion inhibition and rust prevention performance

Abstract

The invention provides a semi-synthetic aluminum alloy processing fluid and a preparation method thereof, wherein the semi-synthetic aluminum alloy processing fluid comprises the following components in parts by weight: 30-50 parts of base oil, 0-12 parts of organic synthetic ester, 7-25 parts of emulsifier, 3-10 parts of corrosion inhibitor, 10-15 parts of pH stabilizer, 2-4 parts of antibacterial agent, 0.1-0.5 part of defoamer, 10-30 parts of deionized water. In the semi-synthetic aluminum alloy processing fluid of the present invention, the emulsifier is composed of at least three kinds of compounds whose HLB value is in the range of 1-15 and presents an approximate equidifferential gradient distribution. Through the compounding of the above-mentioned emulsifiers, the Semi-synthetic aluminum alloy processing fluid has excellent extreme pressure lubrication performance, high hardness water aluminum alloy corrosion inhibition performance and ferrous metal rust prevention performance.

Description

technical field [0001] The invention belongs to the field of metal processing fluids, and in particular relates to a semi-synthetic processing fluid which has high hard water anti-rust corrosion inhibition and lubricity and is suitable for aluminum alloy cutting and grinding. Background technique [0002] In recent years, the output of aluminum products in China has been increasing year by year, surpassing the United States to become the world's largest producer of aluminum products. [0003] In the process of mechanical forming of aluminum products, processing lubricating fluid is a necessary supporting material, and it is also an important factor affecting whether the size, appearance, surface quality, and performance of aluminum alloy products can meet the requirements. Aluminum alloy processing fluid has lubricating, antirust , cleaning and cooling performance, can effectively prevent problems such as knife sticking, rough processing surface, oxidation and loss of gloss ...
