Description
Technical field
The present invention relates to paint field, and in particular to a kind of transparent powder paint.
Background technology
Powdery paints be it is a kind of prolong born Novel environment-friendlymaterial material based on petrochemical materials, mainly by low molecule
Resin, auxiliary agent, filler etc. are measured, prepared under certain conditions, spray, toasted and formed with certain appearance, gloss, face
Color, and play the film of anti-corrosion and decoration function in object surface.Powdery paints in actual application, such as outdoor gate,
Balcony guardrail etc..After a period of time, film will occur to change to a certain degree, such as gloss decline, colour-darkening or cool white, painting
There is rust spot, crackle etc. in layer surface.
Powdery paints practitioner is in lifting powdery paints weatherability at present, mainly using following several method：1st, select
Suitable polyester resin is selected, fully list is synthesized from weatherability angle, design molecular structure, selection in the building-up process of polyester
Body.2nd, it is modified using different resin alloys, such as Organic fluoride, the cold spelling blending and modifying of organosilicon.3rd, inorganic filler selects, such as organic
The technological means such as the titanium dioxide of silicon coating lift coating weatherability.4th, auxiliary agent is added, UV absorbents is such as added and absorbs 295-350nm
The ultraviolet light of wave band.But these current means are concentrated mainly on the single film in surface.Meanwhile add auxiliary agent or cold spelling
There is certain limitation etc. means, be exposed to the sun in Florida experimentally, migration can be produced, final decay is very big.
The content of the invention
The object of the present invention is to provide a kind of transparent powder paint, transparent powder paint of the invention has high glaze, height
The advantages that hardness, good, resistance to chemical corrosion is good, anti-yellowing property is good, good decorative property transparency, it is various to be that one kind is widely used in
Metal works Lacquer finish transparent powder paint.
The present invention provides a kind of transparent powder paint, and the powdery paints includes following components by weight percent raw material：
Further, the polyester resin is high transparency polyester resin.
Further, the curing agent is TGIC or HAA.
Further, the levelling agent is 486 levelling agent of Troy, and wetting agent is 520 wetting agent of Troy, and defoamer is
Troy defoamer.
Further, the stearic acid is stearic acid 1895.
Further, the dyestuff is high temperature resistant Weather-proof dye.
Further, the delustering agent is acrylic matting agent.
Technical solution of the present invention also provides a kind of preparation method of above-mentioned transparent powder paint, comprises the following steps：
Above-mentioned each raw material is mixed in proportion, by mixing extrusion in extruder, after then tabletting crushes, then by micro mist
Broken machine crushes, sieving, up to the transparent powder paint.
Technical solution of the present invention also provides a kind of application of above-mentioned transparent powder paint, by above-mentioned coating applied metal work
Part.
Further, the coating is sprayed by corona electrostatic.
Transparent powder paint provided by the invention uses high transparency polyester resin as main ingredient, and with good resistance to
Hot, weatherability TGIC or HAA is as curing agent so that transparent powder paint has excellent weatherability, adhesive force and soft
Toughness；4 kinds of auxiliary agents such as levelling agent, wetting agent, defoamer, stearic acid are with the addition of, the addition of above-mentioned auxiliary agent significantly improves polyester
The levelability of resin, wetability so that coating has the advantages that flowing flow leveling, the transparency, the adhesive force of brilliance；It with the addition of
High temperature resistant Weather-proof dye, can recall the transparent powder paint of a variety of colors, be sprayed on various metal hardware workpiece surfaces；This
Outside, acrylic matting agent is also added, the extinction effect of delustering agent is good, can obtain 1-
60% any gloss.The dosage of filler and pigment is reduced in otherwise see-through powdery paints to the greatest extent, has improved as far as possible
Resin ratio shared in transparent powder paint, be conducive to improve the high transparency effect of transparent powder paint, impact resistance,
Pliability and adhesive force.
Compared with prior art, the present invention have the beneficial effect that：
1st, transparent powder paint provided by the invention uses high transparency polyester resin as main ingredient, and with good
Heat resistance, the TGIC of weatherability or HAA are as curing agent so that transparent powder paint have excellent weatherability, adhesive force and
Pliability.
2nd, transparent powder paint provided by the invention is suitable for industrial continuous spraying and application, wide with application range
Advantage, there is provided diversified decorative product.
3rd, product of the invention due to be 100% solid part, without any solvent, not only accumulating is convenient, but also can recycle
Reuse, utilization rate is up to more than 95%.Overcome solvent-borne type luminous paint, due to there is a solvent flashing, a part is waved during use
Hair falls, and a part is attached on coating equipment, and utilization rate only has the shortcomings of 30-40%.
4th, transparent powder paint of the invention has high glaze, high rigidity, the transparency is good, resistance to chemical corrosion is good, resistance to
The advantages that xanthochromia performance is good, good decorative property, is that one kind is widely used in various metal works Lacquer finish transparent powder paints.
