Abstract

The invention discloses a flaky nano metal zinc powder processing method. The flaky nano metal zinc powder processing method comprises the following steps that 1, grinding is performed: nano zinc particles are firstly put in a horizontal type grinding machine, a solvent is added, and grinding is performed for 48 hours under the effect of a grinding medium; 2, staged processing is performed: the formed zinc powder flaky after grinding is separated out; 3, secondary grinding is performed: the nano zinc particles which do not form flakes are returned to the horizontal type grinding machine, the solvent is removed, a hyperdispersant is added, grinding continues for more than 24 hours till it is obviously found that the granular zinc powder is already converted into flaky zinc powder under a microscope; 4, coating is performed: the flaky zinc powder is coated by adopting a surface treating agent, the stacking density of the flaky zinc powder is controlled to be below 1-2 during coating, and flaky nano metal zinc powder is obtained. The flaky nano metal zinc powder prepared by adopting the flaky nano metal zinc powder processing method has the characteristics of good dispersing performance, low stacking density and the like, can locally shield and interfere electromagnetic waves and wireless signals and achieves the effect of gaining the advantages in information competition.

Description

The processing method of flake nano metal zinc
Technical field
The present invention relates to a kind of processing method of flake nano metal zinc.
Background technology
Haze is a kind of natural phenomena of atmospheric pollution, and the granule in haze is generally pm2.5, and that is, particle diameter is 2.5 Micron is following.According to this phenomenon, the materials processing with anti-electromagnetic wave and signal interference can be become particle diameter 1-2 micron Hereinafter, the mist of aeroge by suitable process for treating surface, can be formed in an atmosphere with the air-flow in air and hydrone Haze.Because these granules all have the effect of interference electromagnetic wave, the haze being formed just be provided with desired anti-electromagnetic wave and The effect of signal interference, this can play a role for winning information war.
But at present, the particle dispersion of such artificial haze can be poor, and bulk density is higher, and surface mobility is poor, causes The ability of its anti-electromagnetic wave and signal interference is weaker.
Content of the invention
The purpose of the present invention is can be poor for solving the particle dispersion of artificial haze at present, and bulk density is higher, surface Poor fluidity, causes its anti-electromagnetic wave and the weaker technical problem of ability of signal interference.
In order to solve above-mentioned technical problem, the present invention provides a kind of processing method of flake nano metal zinc, including such as Lower step:
(1) grind: first Nano-Zinc granule is placed in horizontal mill, adds solvent, in the presence of mill is situated between, grinds 48 Hour；
(2) staged care: the zinc powder forming lamellar after grinding is separated；
(3) secondary grinding: the Nano-Zinc granule not forming lamellar returns in horizontal mill, removes solvent, adds oversubscription Powder continues to grind more than 24 hours, until substantially finding that granular zinc powder has turned to zinc flake under the microscope；
(4) coat: using surface conditioning agent, zinc flake is coated, period, by the bulk density control of zinc flake System, in below 1-2, obtains flake nano metal zinc.
Further, hyper-dispersant described in step (3) be acrylic copolymer, the trade mark be ch-10b, ch18, ch-7, Mixture more than one of hyper-dispersant of ch13e, or two of which.
Further, surface conditioning agent described in step (4) is low-carbon (LC) polyhydroxy-alcohol, Long carbon chain unit alcohol, Long carbon chain list First acid, low-carbon (LC) polyhydroxy acid, organic amine surfactant, esters surface active agent, nonionic surfactant, hydroxyl High molecular polymer and one of its esters and carboxylic high molecular polymer and its esters, or more than two of which mixed Compound.
Further, the high molecular polymer of described hydroxyl and its esters be polyethylene glycol 1500, Macrogol 4000, One of polymethyl acrylate, butyl polyacrylate and sodium polyacrylate, or mixture more than two of which；
Described carboxylic high molecular polymer and its esters are polyethylene glycol 1500, Macrogol 4000, polyacrylic acid One of methyl ester, butyl polyacrylate and sodium polyacrylate, or mixture more than two of which.
Further, mill Jie described in step (1) is the ball being made up of zirconium oxide or corundum of diameter 0.5-3 millimeter.
Further, the speed ground described in step (1) is more than 1000 revs/min.
It is good that the flake nano metal zinc being obtained using the present invention has a dispersive property, the low characteristic of bulk density；Then The flake nano metal zinc that these diameters are much smaller than pm2.5 is supplied to aircraft after packing, taking as aircraft Band thing, required overhead or place there is explosion or sprinkling so that these flake nano metal zincs in the air and air Form the guard of a kind of aerosol state or haze, shadow shield and interference are carried out to location electromagnetic wave and wireless signal, reaches The effect getting the mastery in compete in information.
Specific embodiment
Presently in connection with embodiment, the present invention is further detailed explanation, and the application of the present invention is not limited to following Embodiment, any pro forma accommodation that the present invention is done falls within protection scope of the present invention.
