Technical Field

The invention belongs to the technical field of plastic powder coating, and particularly relates to anti-theft door and profile surface transfer plastic powder.

Background

Plastic spraying is a surface treatment method for spraying plastic powder on parts. The plastic powder is charged by using an electrostatic generator, is adsorbed on the surface of an iron plate or other products, and is then baked at 180-220 ℃ to be melted and adhered on the surface of metal or other objects, the plastic spraying product is mostly used for a box body used indoors, and a paint film has a flat or matte effect. The powder coating is adsorbed on a workpiece by utilizing a corona discharge phenomenon. The process is as follows: the powder coating is fed into the spray gun by means of compressed air gas from powder supply system, and the high-voltage electrostatic generator produces high voltage, and the corona discharge produces dense electric charge near the spray gun, so that when the powder is sprayed out from the gun nozzle, it forms charged coating particles, and under the action of electrostatic force, the charged coating particles are sucked onto the workpiece whose polarity is opposite to that of the powder, and when the sprayed powder is increased, the electric charge is more accumulated, and when it reaches a certain thickness, it can not be continuously adsorbed due to the electrostatic repulsion action, so that the whole workpiece can obtain powder coating with a certain thickness, then the powder is heated, and the powder is melted, leveled and solidified, so that the hard coating film can be formed on the surface of the workpiece.

However, the existing plastic spraying powder has weak adhesive force due to the property problem of the powder, and is easy to fade and fall off, and the prior art has the improvement.

The particle size of the particles is 5-200 μm. The sphere 1 comprises a carboxyl end group and a hydroxyl end group. The acid value of the sphere 1 is 50-55. The curing agent layer 6 is triglycidyl isocyanurate curing agent. The pigment dispersant layer 5 includes polyester, acrylate and urethane. The leveling agent layer 7 is polydimethylsiloxane or polymethylphenylsiloxane.

Through from interior to exterior parcel isocyanate layer 2 in spheroid 1 periphery in proper order, matting agent layer 3, pigment layer 4, pigment dispersant layer 5, curing agent layer 6 and flatting agent layer 7 are constituteed, through set up at spheroid 1 central cavity 8 with set up in flatting agent layer 7 periphery and run through above-mentioned isocyanate layer 2, matting agent layer 3, pigment layer 4, pigment dispersant layer 5, curing agent layer 6 and flatting agent layer 7 communicate to the passageway 9 of spheroid 1 interior cavity 8, cavity 8 in spheroid 1 is covered easily and is connected with adjacent granule through a plurality of passageways 9 that run through the granule when the spraying, increase the joint strength between the granule after the spraying by a wide margin, effectively avoid the condition that turns over look and drop that appear after the plastic powder spraying. Make to react more easily between the component through isocyanate layer 2, it is more abundant to react between each component, the gloss degree on moulding the powder surface is reduced through the flatting agent layer 3 that sets up, reduce illumination reflection efficiency, it is more even to make the color distribute through pigment layer 4 and pigment dispersing agent layer 5, it is better to mould whole impression behind the powder spraying, 6 messenger moulds the powder and have higher intensity after the spraying through the curing agent layer that sets up, extension coating life, it is comparatively level and smooth after the spraying to make through flatting agent layer 7 that sets up.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
