Abstract

The invention belongs to the technical field of metal working fluids, and discloses a multipurpose fully-synthetic cutting fluid for processing neodymium-iron-boron materials and a preparation methodof the multipurpose fully-synthetic cutting fluid. The cutting fluid comprises the following components in percentage by weight: 10-20% of organic alcohol amine, 5-15% of organic carboxylic acid, 1-10% of extreme pressure agent, 1-10% of boundary lubricant, 0.5-8% of metal corrosion inhibitor, 0.2-1% of wetting agent, 0.2-1% of settling agent, 0.5-2% of antiseptic bactericide, 0.1-1% of defoamingagent, 0.3-2% of water softener, 0-2% of pH regulator, 2-10% of other assistants and the balance of water. The fully synthetic cutting fluid does not contain substances which are toxic and harmful tohuman bodies, does not pollute the environment, meets the requirements of various processing modes of neodymium iron boron materials, can meet the requirements of lubrication, rust prevention, cleaning and cooling required by neodymium iron boron processing, and improves the recycling economic value of processing scraps.

Description

technical field [0001] The invention belongs to the technical field of metal working fluids, and relates to a water-based fully synthetic cutting fluid used for processing NdFeB magnetic materials and a preparation method thereof. Background technique [0002] NdFeB material is an excellent permanent magnet material. There are three main molding processes: sintering molding, bonding molding, and injection molding. Among them, sintered NdFeB is currently the most widely used NdFeB material. Sintered NdFeB is made by powder sintering, only to obtain a blank, and subsequent machining (mainly slicing, grinding, drilling, etc.) is required to obtain the desired shape of the magnet. [0003] Sintered NdFeB contains rare earth elements, has active chemical properties, is prone to galvanic reaction, and is made by powder sintering. It has typical powder metallurgy characteristics, that is, it has a microporous structure. The use of general water-based cutting fluid can easily lead t...
