The raw materials adopted by the invention are all environment-friendly aqueous media, can be naturally degraded in natural environment and have no pollution to the environment.
Description
Technical Field
The invention belongs to the technical field of antirust grinding fluid, and particularly relates to antirust grinding fluid and application thereof in bonding neodymium iron boron magnets.
Background
After the bonded neodymium iron boron magnet is subjected to compression molding and curing, sharp edges can be generated at the corner edges, and due to the existence of the sharp edges, the corrosion resistance of the magnet is greatly reduced after electrophoresis and roll spraying coating, and the subsequent installation of the magnet and the application after installation are also seriously influenced. In order to avoid the adverse effects, the magnet after being pressed and formed needs to be polished, chamfered and chamfered by brown corundum abrasive, the chamfering process comprises a dry grinding method and a wet grinding method, the dry grinding method is to directly grind the magnet by the brown corundum abrasive without adding grinding fluid, the method can prevent the magnet from rusting, but the chamfering force is not easy to control, the edge and corner of the magnet are easily removed, and the wet grinding method is to add proper aqueous grinding fluid into the brown corundum abrasive, so that the edge and corner of a workpiece can be prevented from being lost in the grinding process, and the workpiece can be prevented from rusting in the grinding process. The traditional method is to add sodium nitrite into the formula of the aqueous grinding fluid for rust prevention, and the sodium nitrite as an aqueous rust inhibitor has good effect, but is carcinogenic and not beneficial to environmental protection.
Disclosure of Invention
The purpose of the invention is as follows: the invention aims to provide the antirust grinding fluid for the bonded neodymium iron boron magnet and the application thereof aiming at the defects of the prior art.
The technical scheme is as follows: the invention relates to an antirust grinding fluid for a bonded neodymium iron boron magnet, which comprises the following components in percentage by mass: 4-6% of triethanolamine borate oleate, 0.6-1.2% of triethanolamine, 640.6-1.2% of polyether L, 0.6-0.8% of trisodium phosphate, 0.1-0.3% of an antifoaming agent, 0.05-0.1% of a preservative and the balance of pure water.
Further perfecting the technical scheme, the paint comprises the following components in percentage by mass: 5% of triethanolamine borate oleate, 1% of triethanolamine, 641% of polyether L, 0.7% of trisodium phosphate, 0.2% of defoaming agent, 0.1% of preservative and 92% of pure water.
Further, the conductivity of the pure water is less than or equal to 10 mu S/cm.
The invention also provides application of the antirust grinding fluid in bonding neodymium iron boron magnets.
Further, the application of the antirust grinding fluid in the bonded neodymium iron boron magnet comprises the following steps: after the bonded neodymium iron boron magnet is pressed, molded and solidified, the rust-proof grinding fluid is added into the brown corundum abrasive, and the corners and edges of the bonded neodymium iron boron magnet are ground by a wet grinding method.
Has the advantages that: compared with the prior art, the invention has the advantages that: the invention does not adopt sodium nitrite as an antirust component, but adopts other various environment-friendly water-based antirust agents to replace sodium nitrite, can be naturally degraded in natural environment, and has no pollution to the environment, thereby achieving the effect of both antirust and environment protection. The rust-proof grinding fluid provided by the invention is used for grinding the corners and edges of the bonded neodymium iron boron magnet, and after multiple uses, the chamfered workpiece corners and edges are verified to be round and smooth, and the rust-proof performance is excellent.
