Antirust cutting solution for cast iron workpiece of whole diesel engine and preparation method for antirust cutting solution

Abstract

The invention discloses an antirust cutting solution for a cast iron workpiece of a whole diesel engine and a preparation method for the antirust cutting solution. The antirust cutting solution has high cooling performance, lubricating performance, cleaning performance and antirust performance and comprises the following raw materials in percentage by mass: 10 to 14 percent of agent A, 10 to 45 percent of agent B, 1 to 5 percent of sodium oleate, 1 to 7 percent of polyether (2010), 1 to 9 percent of industrial glycerin, 0.5 to 1.0 percent of isothiazolinone and the balance of water, wherein the agent A comprises the following raw materials in percentage by mass: 2 to 6 percent of phytic acid, 8 to 10 percent of normal temperature steel surface treating agent, 1 to 3 percent of ammonium hydrogen phosphate, 3 to 7 percent of triethanolamine, 3 to 5 percent of polyethylene glycol, 0.6 to 1.2 percent of organic silicon antifoaming agent and the balance of water; and the agent B comprises the following raw materials in percentage by mass: 2 to 4 percent of sodium carbonate, 10 to 20 percent of sodium nitrite, 10 to 16 percent of triethanolamine and the balance of water.

Description

technical field [0001] The invention relates to a metal cutting fluid, in particular to a rust-proof cutting fluid for diesel engine cast iron workpieces with good cooling performance, lubricating performance, cleaning performance and antirust performance and a preparation method thereof. Background technique [0002] During the metal cutting process, the friction between the tool and the workpiece will cause the temperature of the workpiece processing area to rise above 1000°C, and the surface load of the part where the tool contacts the uneven surface of the workpiece can reach 5000N / mm 2 , so the workpiece will cause local welding phenomenon when cutting. In order to reduce the cutting temperature and cutting force, cutting fluid must be used in the metal cutting process, and water-based cutting fluid is a commonly used one. [0003] During the processing of cast iron workpieces of diesel engines, it is necessary to change the machine tool several times for cutting proce...

AI Technical Summary

Problems solved by technology

At present, the biggest problem of water-based cutting fluid used in the cutting process is the poor anti-rust ability, so that the cast iron workpiece of the diesel engine is transferred from the front machine tool to the background machine tool, and the surface is rusted before it is machined again.
