Abstract

The invention belongs to the field of metal machining liquid and particularly relates to an aluminum alloy corrosion inhibition composite and a preparation method thereof. The aluminum alloy corrosion inhibition composite specifically comprises oleic soap compounds, fatty acid potassium salt, triethanolamine borate, an auxiliary additive and water. The oleic soap compounds comprise heterogeneous alcohol oleic soap and triethanolamine oleic soap; and meanwhile the invention furthermore provides a method for preparing the aluminum alloy corrosion inhibition composite. By means of the aluminum alloy corrosion inhibition composite and the preparation method thereof, the technical problems that an existing metal machining liquid corrosion inhibitor pollutes the environment and is poor in anti-rust property and corrosion inhibition are solved, and the aluminum alloy corrosion inhibition composite does not contain the phosphorus element and is a green and environmentally-friendly metal machining liquid additive; and meanwhile, the aluminum alloy corrosion inhibition composite furthermore has excellent corrosion inhibition, rust protection and cleaning functions, and the preparation method of the aluminum alloy corrosion inhibition composite is simple in operation and low in cost.

Description

technical field [0001] The invention belongs to the field of metal working fluids, and in particular relates to an aluminum alloy corrosion inhibiting composition and a preparation method thereof. Background technique [0002] Metalworking fluid is a liquid used in metalworking, mainly for lubrication, cooling, rust prevention and cleaning. At present, the pH of metalworking fluids commonly used in the market is between 8 and 9.5. Under this pH value, ferrous metals are easier to rust, and most bacteria cannot survive, which is conducive to the recycling of metalworking fluids, maintaining the performance of processing fluids, Reduce the manufacturer's production cost and use cost. [0003] With the wide application of aluminum alloys in industry, aluminum alloy processing fluids are increasingly concerned by the metal processing industry. Therefore, the requirements for aluminum alloy processing fluids are getting higher and higher, and the requirements for aluminum alloy ...
