Description

A kind of inexpensive environment-friendly preparation method thereof of Nanometer Copper
Technical field
The present invention relates to a kind of inexpensive environment-friendly preparation method thereof of Nanometer Copper, belongs to Nanometer Copper preparing technical field.
Background technology
The development of copper nanoparticle is a key technology that possible bring copper revolutionary variation, has important theory significance and reality With value.The preparation method of industrial superfine cupper powder is mainly atomization and electrolysis.Atomization is that a kind of tradition is easy and effective Preparation method of nano material, but the anti-oxidant problem that the method runs into Nanometer Copper preparation process is difficult to solve always；It is open Number CN101818364A discloses a kind of preparation method of copper nanoparticle, and Nanometer Copper is prepared by electrolysis in this method Powder, and electrolysis high energy consumption, the copper particle being prepared are larger, and intermediate demand adds various organic reagent increase production costs And pollution environment.
Solution phase chemical reduction refer to use with certain reducing power reducing agent, by the bivalent cupric ion in solution also As far as zero-valent state, different-grain diameter rank, uniform powder are obtained by controlling various technological parameters.Liquid phase reduction is prepared and received Rice copper powder has the advantages of its is unique, and such as equipment is simple, technological process is short, easy industrialized production, but is up to the present all difficult to Large-scale industrial production is carried out, is primarily due to add some reducing agents such as formaldehyde, sodium hypophosphite, boron hydride（It is open Number CN101372037A）, hydrazine hydrate（Haitao Zhu et al. Nanotechnology, 2005, 16: 3079）, it is organic Reducing agent（Publication number CN102941350B, CN102586800A）Etc. that can cause, its production cost is too high, while some of which Reducing agent has severe toxicity, and post processing cost is high, and some reducing powers are poor, Cu2+Reduction is not thorough and cannot get pure Nanometer Copper etc..
The hot method of polyalcohol is solvent and reducing agent using polyalcohol, and the presoma for being heated to certain temperature reducing metal salt comes Prepare a kind of method of metal nanoparticle.Crystal nucleation and growth course are separated in this method, can be real by changing Condition is tested to control the size of nano particle and distribution, the polyalcohol for such reaction is usually using ethylene glycol as representative （Journal of Materials Chemistry, 1993, 3(6): 627-632）.The hot method reduction of ethylene glycol prepares nanometer The dominant mechanism of metal simple-substance is that ethylene glycol decomposes generation acetaldehyde at high temperature, and acetaldehyde has strong reducing property, by metal ion also Originally it was metal simple-substance.It is solvent to open the report such as bright with ethanol, adds NaOH and CuSO4, 200OIt is anti-that ethanol heat is carried out under the conditions of C A nanometer Cu should can be prepared（Qinghai Normal University's journal, 2005 (2): 26-28）, but in preparation process, generation Acetic acid sodium crystal, it is unfavorable for mass transfer, hinders reaction effectively to carry out, and be difficult to separate with Nanometer Copper powder, solvent is all ethanol, system Standby cost is high.
The content of the invention
The object of the present invention is to the defects of in order to improve the high pollution of Nanometer Copper traditional preparation methods, high energy consumption, high production cost, The present invention provides a kind of inexpensive environment-friendly preparation method thereof of Nanometer Copper.
The technical scheme that the present invention realizes is as follows：A kind of inexpensive environment-friendly preparation method thereof of Nanometer Copper, methods described pass through Nanometer Copper powder is prepared in the hot method of water-alcohol, and step is as follows：
（1）Using soluble copper salt as raw material, the stirring that is added to the water obtains homogeneous solution, adds a certain amount of small molecular alcohol, Stir, then in the case of stirring, add alkali lye, continue to stir.
（2）By step（1）In obtained liquid and solid be transferred in water heating kettle, 160OC to 200OUnder the conditions of C, water After heat 6 h to 12 h, room temperature is cooled to, is filtrated to get filtrate and brick-red sediment, with distilled water and ethanol by sediment Clean up, 30~60OC is dried in vacuo 12~24 h, obtains Nanometer Copper powder.
Described alcohol is methanol, one kind in ethanol or mixture.
Described soluble copper salt is copper sulphate, copper nitrate, copper chloride, one or several kinds of mixtures of copper acetate.
Described alkali lye is sodium hydroxide, one kind in potassium hydroxide solution or mixed liquor.
The mol ratio of the copper and alcohol is 1/5-1/1, and the volume ratio of alcohol and water is 1/10-1/1.
The concentration of the alkali lye is 0.01-5 mol/L, and the amount ratio of the material of alcohol and alkali is 1/1-1/2.
The vacuum drying temperature is 30-60OC, drying time be：12-36 h.
The invention has the advantages that Nanometer Copper powder is prepared by the hot method of water-alcohol in the present invention, raw material is inexpensively easy , alcohol dosage is few, and main organic product is hydrochlorate corresponding to alcohol, be can be recycled, production cost is low.This method need not Poisonous reducing agent is added, it is green；Product is easily isolated and collected, and preparation method and technical process are simple, easily realizes industry Metaplasia is produced.
