Abstract
A metallic powder for powder electrostatic spraying is prepared from the following components by weight: 21.80% of polyester, 19.90% of epoxy resin, 1.90% of an accelerator, 23.32% of barium carbonate, 15.91% of ultrafine barium, 14.41% of titanium dioxide, 0.95% of a leveling agent, 1.14% of a brightener, 0.38% of bronze powder, 0.28% of silver powder and 0.01% of graphene. The metallic powder has simple components in reasonable ratio; the added graphene microchip enhances the electrostatic spraying performance; and after spraying, the powder has good fusion performance, strong absorption and no falling, so as to greatly benefit the quality of spraying and significantly improve product quality.
Description
Technical field
The present invention relates to coating process technical field, be specifically related to a kind of electrostatic powder spraying metal tonerEnd.
Background technology
Electrostatic spraying utilizes high-pressure electrostatic corona field principle. Metal guide flow cup on lance head connects high pressureNegative electricity, is coated with workpiece grounding to form positive pole. Between spray gun and workpiece, form stronger electrostatic field. Work as fortuneGas carrier (compressed air) by powdery paints from powder barrel in the time that duff pipe is delivered to the diversion cup of spray gun, itsProduce intensive electric charge around, negative electrical charge on powder belt, under electrostatic force and compressed-air actuated effect, powderEnd is adsorbed on workpiece uniformly, through heating, powder melts solidify (or plasticizing) become evenly, continuously,Smooth, smooth film.
The factor that affects film performance in Powder Electrostatic Coating Technology is except relevant with spraying parameter, also withPowdery paints characteristic is relevant, and therefore, the selection of powdery paints composition is also most important.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of composition comparatively simple, and spraying effect is goodElectrostatic powder spraying bronze powder.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of electrostatic powder spraying bronze powder, made by the component of following mass percent:
Described Graphene is selected Graphene microplate, and described Graphene microplate is long brilliant in three-dimensional honeycomb modeGenerate, four valence electrons of each carbon atom form covalent bond in bond live, can not form orientationMobile electron stream, so just can not conduct electricity, after generating, Graphene crystal utilizes the nano-milled mode of wet type,Grind with single direction, generation thickness is nanometer, the Graphene microplate that area is micronization.
The invention has the beneficial effects as follows: composition of the present invention is comparatively simple that reasonable mixture ratio increases Graphene micro-Sheet, promotes electrostatic spraying performance, and after spraying, powder fusion character is good, and adsorptivity is strong, and difficult drop-off, to sprayBe coated with quality greatly useful, significantly Improving The Quality of Products.
Detailed description of the invention
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understandSeparate, below in conjunction with specific embodiment, further set forth the present invention.
Embodiment 1
A kind of electrostatic powder spraying bronze powder, made by the component of following mass percent:
Described Graphene is selected Graphene microplate, and described Graphene microplate is long brilliant in three-dimensional honeycomb modeGenerate, four valence electrons of each carbon atom form covalent bond in bond live, can not form orientationMobile electron stream, so just can not conduct electricity, after generating, Graphene crystal utilizes the nano-milled mode of wet type,Grind with single direction, generation thickness is nanometer, the Graphene microplate that area is micronization.
Press powdery paints formula by fully premixed of proportioning raw material → in mixing tank → common by extruderExtrude → compressing tablet → pulverize → grind → sieve → packed products.
More than show and described general principle of the present invention and principal character and advantage of the present invention. One's own professionThe technical staff of industry should understand, and the present invention is not restricted to the described embodiments, above-described embodiment and explanationThat in book, describes just illustrates principle of the present invention, without departing from the spirit and scope of the present invention,The present invention also has various changes and modifications, and these changes and improvements all fall into claimed model of the present inventionIn enclosing. The claimed scope of the present invention is defined by appending claims and equivalent thereof.
