Abstract
The invention discloses a high-weather resistance polyester type powder coating which comprises the following components in percentage by weight: 55%-65% of polyester resin, 15%-22% of titanium dioxide, 12%-16% of barium sulfate, 3%-6% of curing agents, 0.5%-1.5% of leveling agents, 0.5%-1.5% of brightening agents, 0.3%-0.7% of auxiliary agents and 0.3%-0.7% of inorganic pigments. The high-weather resistance polyester type powder coating has the advantages of good heat resisting property and weather resisting property and excellent chemical corrosion resistant property and can be widely applied to the coating of anti-corrosion layers of outdoor structural parts such as metal guardrails, railways and road transport facilities.
Description
Technical field
The present invention relates to art of powder coatings, particularly a kind of high-weatherability polyester type powder paint.
Background technology
Powder coating is a kind of green coating of non-volatile solvent, have solvent-free, low pollution, material use efficiency is high, the advantages such as energy expenditure is low, be widely used in pipeline, metal, the facility fields such as outdoor structural part, after utilizing resin and solidifying agent heating, there is crosslinking reaction in powder coating, form not molten hard coat, temperature is high again, this coating can only be decomposed, and can be not softening as thermoplastic resin coating, thereby there is stronger mechanical property, therefore member out of doors, as metal guardrail, railway, in highway communication facility, the powder coating that adopt as corrosion protection coating more, but the existence of aromatic oxide group in resin, coating is extremely irritated to ultraviolet ray, so that weathering resistance is not high, easily yellowing in baking or solar radiation process, efflorescence, affect its mechanical property and decorate properties, the coating that particularly long-term exposure was exposed to the sun in summer, be more prone to aging.
Develop at present, be applicable to outdoor powder coating and mainly contain 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 coating is that in current powder coating, weathering resistance over-all properties is a kind of preferably, but TGIC has strong skin irritation and potential carinogenicity, forbidden using in coating by some countries, therefore develop a kind of weathering resistance strong, the weathering resistance powder coating that over-all properties is high, it is this area technical problem urgently to be resolved hurrily always.
Summary of the invention
For the problems referred to above, provide a kind of weather resistance strong, the polyester type powder paint that mechanical characteristic is good, is applied to the preservative coat of the outdoor structural parts such as metal guardrail, railway, highway communication facility, and the present invention is achieved in that
A kind of high-weatherability polyester type powder paint, it forms component and weight ratio is: vibrin 55-65%, titanium dioxide 15-22%, barium sulfate 12-16%, solidifying agent 3-6%, flow agent 0.5-1.5%, brightening agent 0.5-1.5%, auxiliary agent 0.3-0.7%, mineral dye 0.3-0.7%.
Preferably, in the present invention, in high-weatherability polyester type powder paint, formation component and weight ratio are: vibrin 60%, titanium dioxide 18%, barium sulfate 14%, solidifying agent 5%, flow agent 1%, brightening agent 1%, auxiliary agent 0.5%, mineral dye 0.5.
Preferably, in the present invention, described solidifying agent is solidifying agent TEFC.
Preferably, in the present invention, described vibrin is the one in vibrin P885, P880, P6800, and described flow agent is the one in flow agent GLP-503, flow agent GLP-504, flow agent GLP-505.
Preferably, in the present invention, described brightening agent is TL701.
Preferably, in the present invention, described mineral dye is the one in molybdenum red, titanium nickel yellow or cobalt green.
In the present invention, when vibrin and solidifying agent TEFC are crosslinked, paint having no volatile substances produces, can make the film of free of pinholes, and system homogeneous, stable, adjustable, there is good heat-resisting and weather resistance, more than the coating artificial accelerated aging time that adopts powder coating of the present invention to prepare can reach 1000h, powder coating of the present invention has excellent resist chemical performance simultaneously, the good stability of powder coating own, nonhygroscopic, do not lump, not with other compositions, as pigment, auxiliary agents etc. react, there is good storage capability, can be widely used in being applied to metal guardrail, railway, during the preservative coat of the outdoor structural parts such as highway communication facility applies.
