Abstract
The invention relates to a degreasing agent for a permanent magnet material. The water-soluble degreasing agent comprises alkaline materials, a cleaning auxiliary agent and a surface active agent, wherein the alkaline materials are selected from at least two of sodium hydroxide, potassium hydroxide, sodium carbonate, sodium hydrogen carbonate, trisodium phosphate or sodium pyrophosphate; the cleaning auxiliary agent is selected from at least one of organic polybasic phosphonic cleaning auxiliary agents, or a mixture of at least one of the organic polybasic phosphonic cleaning auxiliary agents and at least one of inorganic phosphate cleaning auxiliary agents; and the surface active agent is a low-foam non-ionic surface active agent. According to the invention, the degreasing agent provided by the invention has good wettability, permeability and emulsibility, high degreasing speed, higher grease dirt capacity and long service life, and can prevent grease dirt from being adsorbed again; and meanwhile, by using the non-ionic surface active agent, the foam is little, the washing performance is superior, the water can be softened, and the corrosion of the permanent magnet material in the degreasing agent can be avoided.
Description
Technical field
The present invention relates to a kind of degreaser, particularly a kind of degreaser that is used for permanent magnet material belongs to the surface treatment technology of material field.
Background technology
Can application of neodymium iron boron (NdFeB) permanent magnet material in recent years and development be very rapid, be to be related to one of gordian technique that can Nd-Fe-Bo permanent magnet material apply and effectively protect Nd-Fe-Bo permanent magnet material.Nd-Fe-Bo permanent magnet material mainly is to be prepared from by powder metallurgical technique by elements such as rare earth metal neodymium, iron and boron.As the strongest present magneticsubstance, be widely used in all fields such as electroplating device, machinery, medical treatment, automobile, application prospect is very wide.
The prerequisite of Nd-Fe-Bo permanent magnet material widespread use is to resolve the anticorrosion problem of Nd-Fe-Bo permanent magnet material.As the porous material that a kind of powder metallurgical technique is prepared from, wherein rich neodymium phase, neodymium iron boron principal phase and borderline phase are easy to form intergranular corrosion.Simultaneously, rear earth element nd in the neodymium iron boron powder alloy, character is active, make the corrosion resisting property of whole Nd-Fe-B alloys become very poor, very easily corrosion in damp and hot environment, because of corrosion failure causes the decline or the damage of magnetic property, had a strong impact on the work-ing life of Nd-Fe-B permanent magnet, reduced the stability and the reliability of product.The magnetic property of Nd-Fe-Bo permanent magnet material and its weave construction have very big relation, and wherein, the principal phase of Nd-Fe-B permanent magnet is the main source of magnet magnetic property, and the coercitive relatively contribution of rich neodymium is maximum.After Nd-Fe-Bo permanent magnet material corrodes, the magnetic property of material will be greatly weakened.Therefore, the anticorrosion problem of Nd-Fe-Bo permanent magnet material is to need one of subject matter that solves always.
The anti-corrosion method that is used for Nd-Fe-Bo permanent magnet material at present has a lot.Electronickelling (CN1928163, CN1928163), electro-galvanizing (CN1421547A, CN1056133A, CN1056133) are wherein arranged, electroplate MULTI-LAYER NICKEL, copper facing (CN1514889A), several different methods such as phosphatization, electrocoating paint.
Before all electroplating processes, in order to make coating and matrix good binding, it is a step necessary procedure that material matrix is carried out degreasing degreasing.Degreasing degreasing thoroughly will the very big negative impact to the anticorrosion generation of Nd-Fe-Bo permanent magnet material.
Existing degreaser is primarily aimed at metal or alloy such as ferrous materials or zinc, copper and studies preparation, and the degreaser of obtaining better effects at these material surface energies is used for neodymium-iron-boron permanent magnetic material surface and often can not obtains effect preferably.This be because: neodymium-iron-boron permanent magnetic material surface is loose porous, and the greasy dirt in the space be difficult for to be removed, its corrosion-resistant simultaneously, strong basicity commonly used easily causes the corrosion of material matrix, influences its performance.
