Abstract
The invention discloses powder paint electrified through friction. The paint comprises the following materials by weight percent: 25 to 27 portions of vibrin; 2 to 3.5 portions of TGIC; 5 to 8 portions of BaSO4; 2 to 4.5 portions of CaCO3; 0.5 to 0.9 portion of TIO2; an appropriate amount of paint; and 1 portion of frictional electrification agent TB1. By comparing the invention with the prior art, the powder paint has excellent triboelectric property by adding the frictional electrification agent in the powder paint; the powder can be sprayed to the positions which are inaccessible so that the film is uniform in the thickness and thin paint can be obtained, thus overwhelming the shielding effect of magnetic fields and reaching the spraying effect. The produced film has excellent scratch and impact resistance, which is as beautiful as metal.
Description
Technical field
The invention belongs to powder coating, belong to friction tape electro-powder coating especially.
Background technology
Traditional powder coating produce the magnetic field shielding effect between the turning of irregular workpiece and slit, thereby it is blocked up to make planar section film, and the corner part does not reach coating thickness, loses provide protection, directly has influence on the quality of product in construction process.
Summary of the invention
Technical problem to be solved by this invention provides a kind of friction tape electro-powder coating that is suitable for irregular workpiece.
The technical scheme of technical solution problem of the present invention is: friction tape electro-powder coating, and described coating contains following material and weight part:
Alkyd resin 25-27
TGIC 2-3.5
BaSO
4 5-8
CaCO
3 2-4.5
TIO
2 0.5-0.9
Pigment is an amount of
Charged dose of TB1 1 rubs.
The acid number scope of described alkyd resin is 35-45MGKOH/G, and softening point range is 100-120 degree, and second-order transition temperature (TG) is greater than 60 degree.
Alkyd resin is formed by polyprotonic acid and polyol condensating, and company limited produces by the refreshing arrow chemical industry in Anhui.
Preparation method of the present invention is:
According to the prescription weighing, add then and carry out pre-mixing in the high speed mixer, mixed material is delivered to the hopper of molten forcing machine, makes each composition melt extrude mixing, is uniformly dispersed, be pressed into thin slice by the cooling tabletting machine again, cool off simultaneously, cooled thin slice is fractured into strip when rolling the rod machine, this strip material is transported to that to carry out fine powder in the air classifying mill broken, is the finished product powder after sieving.
Traditional powder coating produce the magnetic field shielding effect between the turning of irregular workpiece and slit, thereby it is blocked up to make planar section film, and the corner part does not reach coating thickness, loses provide protection because of the defective of himself construction; Frictional electrification powder paint has overcome the magnetic field shielding effect, and has reached spraying effect by add the frictional electrification agent in powder when making powder spraying.
Using method of the present invention: the coating that generates by the electrostatic field that a strength of electric field is 1.0-8.0uA, is coated with negative charge on the strip, is that the positively charged quilt of 0.5-5.0uA is coated with on the workpiece attached to strength of electric field then.
The present invention compared with prior art, by in powder, adding the frictional electrification agent, make powder coating have good triboelectric behavior, powder can permeate in spraying process and arrive the position that is difficult to arrive, make coating thickness even, and can obtain thin filming, overcome the magnetic field shielding effect, thereby reach the spraying effect.Filming of generating has good anti-delineation, anti-collision performance and good metal aesthetic feeling.
