Abstract
The open a kind of high-weatherability polyester type powder paint of the present invention, it constitutes component and weight ratio is: polyester resin 55 65%, titanium dioxide 15 22%, barium sulfate 12 16%, firming agent 3 6%, levelling agent 0.5 1.5%, brightener 0.5 1.5%, auxiliary agent 0.3 0.7%, inorganic pigment 0.3 0.7%；This powdery paints has the resist chemical performance that good heat-resisting and weather resistance is excellent, can be widely applied to be applied in the anticorrosive coat coating of the outdoor structures parts such as guardrail wires, railway, highway communication facility.
Description
Technical field
The present invention relates to art of powder coatings, particularly a kind of high-weatherability polyester type powder paint.
Background technology
Powdery paints is the green coating of a kind of non-volatile solvent, has solvent-free, low stain, and stock utilization is high, energy
Amount consumes the advantages such as low, is widely used in the facility fields such as pipeline, metal, outdoor structures part, and powdery paints utilizes resin with solid
Crosslinking reaction after agent heating, form insoluble hard coat, temperature is the highest, and this coating can only be decomposed, without
Softening as thermoplastic resin coating, thus have stronger mechanical performance, component the most out of doors, such as guardrail wires, ferrum
In road, highway communication facility, many employing powdery paints are as corrosion-inhibiting coating, but the existence of aromatic ether group in resin, coating is to purple
Outside line extremely allergy, so that weatherability is the highest, in baking or sunlight irradiation process, easily yellowing, efflorescence, affect its mechanical performance
With decoration performance, particularly it is chronically exposed to the coating being exposed to the sun summer, is more prone to aging.
Develop at present, it is adaptable to outdoor powdery paints mainly has polyester/triglycidyl group isocyanuric acid ester
(TGIC) system, polyester/esters of acrylic acid system, polyurethane system and fluorine-containing, silicon system etc., wherein polyester/TGIC type powder
End coating is that in current powdery paints, weatherability combination property is a kind of, but TGIC has strong skin irritation and dives
Carcinogenecity, forbidden using in coating by some countries, therefore develop a kind of weatherability strong, high weather-proof of combination property
Property powdery paints, is this area technical problem the most urgently to be resolved hurrily.
Summary of the invention
For the problems referred to above, it is provided that a kind of weather resistance is strong, the polyester type powder paint that mechanical characteristic is good is applied to gold
Belonging to the anticorrosive coat of the outdoor structures parts such as guardrail, railway, highway communication facility, the present invention is achieved in that
A kind of high-weatherability polyester type powder paint, it constitutes component and weight ratio is: polyester resin 55-65%, titanium dioxide
15-22%, barium sulfate 12-16%, firming agent 3-6%, levelling agent 0.5-1.5%, brightener 0.5-1.5%, auxiliary agent 0.3-0.7%, nothing
Machine pigment 0.3-0.7%.
Preferably, in the present invention, in high-weatherability polyester type powder paint, constitute component and weight ratio is: polyester resin
60%, titanium dioxide 18%, barium sulfate 14%, firming agent 5%, levelling agent 1%, brightener 1%, auxiliary agent 0.5%, inorganic pigment 0.5.
Preferably, in the present invention, described firming agent is firming agent TEFC.
Preferably, in the present invention, described polyester resin is the one in polyester resin P885, P880, P6800, described stream
Flat agent is levelling agent GLP-503, one in levelling agent GLP-504, levelling agent GLP-505.
Preferably, in the present invention, described brightener is TL701.
Preferably, in the present invention, described inorganic pigment is the one in molybdate red, titanium yellow or cobalt green.
In the present invention, when polyester resin cross-links with firming agent TEFC, paint having no volatile substances produces, and can prepare painting free of pinholes
Film, and system is homogeneous, stable, adjustable, has good heat-resisting and weather resistance, uses coating prepared by powdery paints of the present invention
The artificial accelerated aging time, powdery paints the most of the present invention had the resist chemical performance of excellence, powder up to more than 1000h
The good stability of coating own, nonhygroscopic, do not lump, not with other compositions, as pigment, auxiliary agent etc. react, have good
Storage capability, the anticorrosive coat that can be widely applied to be applied to the outdoor structures parts such as guardrail wires, railway, highway communication facility is coated with
In covering.
