Description
Technical field
The present invention relates to a kind of use high-energy stirring grinding technique, preparation can be used for the production method of the superfine sheet cu-zn alloy powder that prints, spray, belongs to the metal powder material preparing technical field.
Background technology
The production technology of existing sheet of copper Zinc alloy powder is that behind dry method or wet method roller ball mill, technical process such as surface finish modification again, classification are produced behind high annealing with behind cathode copper, the electrolytic zinc fusing mist projection granulating.Not only production technology is long, flow process is complicated for this technology, and fails the organic additive that volatilizees can generate carbon granule and oxidation on the surface of powder granule in high-temperature annealing process, thereby influences metallic luster, has reduced the quality of sheet of copper Zinc alloy powder.
The name be called " manufacture method of squama stratiform alloy powder (application number 90110391.8) " patent disclosure a kind of technology, this process using is carried out the method for dry ball milling under temperature control, control oxygen, feed circulating dry ball milling system with hot-air, and feeding pure oxygen control alloy powder oxidizability, under 150 ℃～250 ℃ conditions, carry out dry ball milling, coat and obtain the flakey alloy powder through painted processing and last film; This method has been got rid of conventional wet ball milling and annealing treating process, but hot-air feeds relatively poor relatively, the painted processing of temperature control operational stability and last film cladding process is also complicated, and powder and pure oxygen are easy to react in surface treatment process, cause the powder vigorous oxidation and turn black, become waste product.The name be called " nano-grade cu-zn alloy powder and manufacture method thereof (application number 200310110526.7) " patent disclosure a kind of technology that adopts coating method, elements such as copper, zinc are deposited on ultra-thin organic film continuously, remove organic film with solvent again, make the nano-grade cu-zn alloy powder after crushed; This method technical process relative complex, control requires also higher, and the component ratio of sedimentary deposit is difficult to precisely control in deposition of alloy layers, can not guarantee the colour stability of powder, and production cost is too high, is difficult to satisfy market demands.The patent application that name is called " flakey copper-gold powder preparation process under the nitrogen protection atmosphere " (application number is 00125773.0) discloses a kind of ball milling new technology, the nitrogen, the control temperature that pass to 90%～95% purity to ball mill are being moved below 15 ℃, and in grinding system, add auxiliary agent based on stearic acid (adding weight ratio be copper bronze 0.2%～5.0%), reduce oxidation reaction, strengthened the metal sense of copper bronze; This method is being carried out ball milling below 15 ℃, make active very poor based on the auxiliary agent of stearic acid to cause the covered effect variation to powder, is unfavorable for the coating and the modification of powder.The patent application that name is called " manufacture method at a kind of scaled metal powder end " (application number 03135633.8) has proposed a kind of method of using high-energy mills to produce flaky metal powder, controlling grinding temperature by the adjusting cooling jacket water yield is 20 ℃～200 ℃, and the feeding inert gas, prevent that oxygen from entering the oxidation that causes metal-powder in the grinding atmosphere; This method is in accurate, the stable control of ball milling temperature, and it is not enough to adjust the aspect existence of sheet cu-zn alloy powder color, and this technology is at flake metal powder in the anticorrosive paints such as Dacroment, what prepare is non-floating type coating, be difficult to use in printing, especially gravure, and this preparation method does not relate to the color of coating.
Summary of the invention
The object of the present invention is to provide a kind of superfine sheet cu-zn alloy powder high efficiency preparation method, adopt horizontal high energy ball mill, regulate machine rotational speed, regulate by the current temperature control measure of uniqueness and suitable milling atmosphere, thereby the degree of oxidation of control alloyed powder, and then improve the gloss and the sheetization of powder metal, overcome problems such as prior art stable processing technique and efficient are not high, production procedure long, obtain powder body material quality is not high.
Superfine sheet ormolu powder, preparation method thereof provided by the present invention, comprise processing steps such as batching, grinding, modification, classification, packing, with granularity is that the spherical ormolu atomized powder of-100～-500 orders, cupric 70%～95%, zinc 5%～30% is as raw material, 0.1%～6.6% amount of auxiliary by the ball material weight ratio of 5～40:1 and raw meal weight, add steel ball (diameter be 3～10mm) and auxiliary agent and mix after, put into the grinding storehouse that horizontal high-energy stirring secret is closed; By the water in the control feeding mixer cooling jacket or the temperature of oil, make the temperature of grinding process of lapping in the storehouse remain on 15～100 ℃, and in grinding the storehouse, feed inert gas (nitrogen or argon gas), make and grind in the storehouse that oxygen content is 0～10%, nitrogen or argon content be 90～100%(so that control the discharging color), keeping then grinding in the storehouse is malleation, under 200～1800 rev/mins rotating speed, ground 15～150 minutes, obtain being more than 60%-300～-1500 purpose copper bronze products; Press 0.1%～3.5% of alloyed powder weight again and add surface modifier, under same atmosphere and temperature conditions, ground 15～50 minutes with 100～300 rev/mins rotating speeds, disperse to polish modification to grinding the cu-zn alloy powder that obtains premenstruum (premenstrua), obtain being more than 70%-300～-1500 purpose copper bronzes; By sieving and grading, obtain-300～-1500 purpose sheet of copper bronze products at last.The auxiliary agent that is added is one or more the mixture in stearic acid, palmitic acid, the polyethylene glycol, and the percentage by weight of itself and alloyed powder raw material is: stearic acid 0.5%～5%, palmitic acid 0.1%～1%, polyethylene glycol 0.1%～0.6%; The surface modifier that is added is one or more the mixture in aluminum stearate, neopelex, the silica, and the percentage by weight of itself and alloyed powder is: aluminum stearate 0.1%～1.5%, neopelex 0.1%～1%, silica 0.1%～1%.
The present invention adopts dry ball milling, the enormous impact power that produces when the high-speed motion by steel ball, make ormolu powder particle in very short time, reach broken and sheetization, avoided powder and the concavo-convex phenomenon of steel ball repeated multiple times collision generation powder surface in the common roller ball mill; Because the use of organic additive and surface modifier makes the alloy powder particle can access better surface modification targetedly, thereby avoided under higher temperature, to carry out surface modification and the problem that causes the non-oxidizability of cu-zn alloy powder to reduce; By the temperature of water in the constant control water jacket or oil, make the temperature of process of lapping obtain control more accurately, the organic additive that makes the metal-powder surface is surface modification better, has further improved the quality of sheet of copper Zinc alloy powder; Control by to the oxygen content of atmosphere in the ball milling cabin has effectively prevented the oxidation of alloyed powder, has realized the purpose of control sheet cu-zn alloy powder color.
This method has been got rid of the annealing flow process of conventional method, special milled processed technology and parameter have been determined at cu-zn alloy powder, selected effective grinding aid, and controlled the ball milling temperature accurately and stably by the temperature of controlling the water that feeds in the cooling jacket, by oxygen content in the control grinding chamber at 0～10% low concentration, thereby realize the grinding of cu-zn alloy powder and the accurate control of modifying process, control the degree of oxidation of cu-zn alloy powder effectively, adjusted sheet of copper Zinc alloy powder color better.Compared with prior art, it is short that this method has production procedure, production efficiency height, stable technical process, advantage such as alloy powder material quality height, the production cost that obtains is low.
