Abstract
The invention relates to rare earth grinding fluid.The rare earth grinding fluid is mainly prepared from, by weight, 2%-5% of rare earth, 1%-2% of a softener, 0.1%-5% of a chelating agent, 1%-15% of a surfactant and the balance organic solvent.The rare earth grinding fluid produced through the technical scheme is simple in production technology and free of mechanical impurities, has the high dispersity and adsorptivity and can keep the state stable for a long time; meanwhile, the softener in the components can soften an oxidation film on the surface of a workpiece to enable the oxidation film to be easily removed through grinding, the material on the surface of the workpiece can be converted into a chelate by the chelating agent after being ground off to be inhibited from being attached to the metal surface again, and therefore the grinding precision is improved.
Description
Technical field
The present invention relates to field of surface treatment, specifically rare earth lapping liquid.
Background technology
The mankind are very close with the relation of chemical industry, in the modern life, almost all be unable to do without chemical products whenever and wherever possible, from material lifes such as clothing, food, shelter, row to the cultural life such as culture and arts, amusement, are required for chemical products and service for it.Some chemical products, in human development history, plays epoch-making important function.Their production and application, even represent certain historical stage of human civilization.
Ultra-precision Turning is the production technology that modern sophisticated industry is important, and it does not require nothing more than high accuracy, high-quality, and requires low cost and high repeatability.And ultraprecision grinding polishing is owing to having the process principle of uniqueness and to features such as process equipment, environmental factors are less demanding, the nanoscale even processing of atom level can be realized, become a pith in Ultraprecision Machining, it is achieved the critical material of ultraprecision grinding polishing is precise finiss goods.At present, the removal unit removing material with abrasive particle has reached nanometer or even sub-nanometer scale, reach so high surface smoothness, the lapping liquid containing abrasive material can be used, or use abrasive material to be fixed on the polished film on thin film, the number steps such as corase grind, middle mill, fine grinding, polishing are divided to carry out, it is also possible to lapping liquid and polished film are combined cross-reference.
Polishing refers to and utilizes mechanical, chemical or electrochemical effect, makes workpiece surface roughness reduce, with the processing method obtaining light, flat surface.It is the modification processing utilizing flexible polishing instrument and abrasive grain or other polishing mediums that surface of the work is carried out.Loading steel ball and fur fragment when essence is thrown in wooden barrel, rotation a few hours can obtain the surface of dazzling light continuously.Finished surface is immersed in polishing fluid to carry out by the polishing of precision scale, and polishing fluid is mixed by the chromium oxide micropowder that granularity is W5～W0.5 and emulsion.In addition with methods such as electrobrightenings.Tradition polishing powder complex manufacturing, it is easy to environment is impacted, and the production cycle is long.
There is presently no a kind of production technology simple, what will not environment be impacted can the rare earth lapping liquid that be specifically designed to polishing of mass production.
Summary of the invention
The present invention is just for above technical problem, it is provided that a kind of production technology is simple, and what will not environment be impacted can the rare earth lapping liquid that be specifically designed to polishing of mass production.
The present invention is achieved through the following technical solutions.
Rare earth lapping liquid, is mainly made up of rare earth, softening agent, chelating agen, surfactant, organic solvent, and each Ingredients Weight percentage composition is: rare earth 2%～5%；Softening agent 1%～2%；Chelating agen 0.1%～5%；Surfactant 1%～15%, surplus is organic solvent.Essential element content in rare earth meets claimed below: CaO+MgO≤3%, CeO >=60%, Nd2O3≥0.2%,La2O3≥28%,Pr2O3≥5%.Softening agent is the one in tartaric acid, stearic acid, pyridine, triethylamine.Chelating agen is NTA or EDTA.Surfactant is one or more the mixture in alkylphenol polyoxyethylene, high-carbon fatty alcohol polyoxyethylene ether, polyoxyethylene carboxylate, fatty acid methyl ester ethyl oxide, sorbitan ester.Organic solvent is mainly alkane solvents.
Adopt the rare earth lapping liquid production technology that technical scheme of the present invention produces simple, without mechanical admixture, there is higher dispersibility and adsorptivity, can keeping in stable condition for a long time, meanwhile, the softening agent in component can make surface of the work oxide-film soften, so as to be easily removed, and the agent that can be chelated after being ground by the material of surface of the work is converted into chelate, thus suppressing it to be attached to metal surface again, improves grinding precision.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
Embodiment 1:
First sorbitan ester 50g is added in 1Kg white oil, it is sufficiently stirred for, add 30g rare earth, it is sufficiently stirred for also ultrasonic disperse 10 minutes, then being continuously added into tartaric acid 15g and EDTA10g under stirring and ultrasonic disperse state, in the end namely a component obtains rare earth lapping liquid of the present invention after adding 15 minutes.
Embodiment 2:
First alkylphenol polyoxyethylene 30g is added in 1Kg white oil, it is sufficiently stirred for, add 40g rare earth, it is sufficiently stirred for also ultrasonic disperse 10 minutes, then being continuously added into stearic acid 15g and NTA20g under stirring and ultrasonic disperse state, in the end namely a component obtains rare earth lapping liquid of the present invention after adding 15 minutes.
Adopt the rare earth lapping liquid production technology that technical scheme of the present invention produces simple, without mechanical admixture, there is higher dispersibility and adsorptivity, can keeping in stable condition for a long time, meanwhile, the softening agent in component can make surface of the work oxide-film soften, so as to be easily removed, and the agent that can be chelated after being ground by the material of surface of the work is converted into chelate, thus suppressing it to be attached to metal surface again, improves grinding precision.
Above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this.All equivalences made according to spirit of the invention change or modify, and all should be encompassed within protection scope of the present invention.
