Abstract
The invention discloses a high luster and high leveling powder coating which mainly consists of the following raw materials in parts by weight: 50-70 parts of saturated hydroxyl polyester resin, 3.7-5.0 parts of triglycidyl isocyanurate, 0.01-0.03 part of anti-yellowing benzoin, 0.4-1.0 part of leveling agent, 0.5-1.5 parts of wetting promoter, 10-30 parts of filler and 0.3-20 parts of pigment. The invention finally solves the problem of insufficient leveling and luster of the coating by means of coating formula optimization and mutual coordination of different assistants and of the mixed use of the wetting promoter and the leveling agent. According to the formula, the high luster and high leveling powder coating with mirror effect can be prepared and has brighter color. The invention has the same indoor and outdoor effect and improves the weather resistance as well.
Description
Technical field
The present invention relates to the high levelling powder coating of a kind of high gloss.
Background technology
Powder coating is as solventless coatings, economy, environmental protection, efficient, performance is remarkable, is subjected to people's welcome.Along with the increasingly stringent to environmental requirement, powder coating is with numerous advantages such as its low pollution, high-decoration, good combination properties and developed rapidly, and progressively replacing conventional solvent type coating.The present market of powder coating is very extensive, and its range of application contains from automotive industry until toy, propelling pencil, and electrical equipment industry is for fear of using solvent paint also all to transfer the use powder coating to.The widespread use of powder coating has benefited from the R﹠D work that powder coating continues, and the performance of powder coating is being improved always.But existing powder coating aspect plane effect as the aspect bright in luster of levelling property, glossy sharpness and high chroma not as good as traditional paint.
Summary of the invention
The invention provides the high levelling powder coating of a kind of high gloss, solved the insufficient problem of powder coating levelling property and gloss, and color is more bright-coloured.
The present invention has adopted following technical scheme: the high levelling powder coating of a kind of high gloss, and it is applicable to outdoor application, is mainly made by the proportioning raw materials of following weight part: saturated hydroxy polyester resin 50-70 part; Triglycidyl isocyanurate 3.7-5.0 part; Anti-xanthochromia st-yrax 0.01-0.03 part; Flow agent 0.4-1.0 part; Wetting enhancer 0.5-1.5 part; Filler 10-30 part; Colorant 0.3-20 part.The acid number of described saturated hydroxy polyester resin is 20-45mgKOH/g; It also comprises the activated silica coupling agent, and its weight part is 0.5-2.0 part.
The high levelling powder coating of a kind of high gloss, it is applicable to indoor application, is mainly made by the proportioning raw materials of following weight part: saturated hydroxy polyester resin 20-40 part; Resins, epoxy 30-50 part; St-yrax 0.01-0.03 part; Flow agent 0.4-1.0 part; Wetting enhancer 0.5-1.5 part; Filler 10-30 part; Colorant 0.3-20 part.
The acid number of described saturated hydroxy polyester resin is 45-85mgKOH/g; It also comprises the activated silica coupling agent, and its weight part is 0.5-2.0 part.
As other coating, the change of prescription has decisive influence to the performance and the construction technology of powder coating.The major part of powder coating character depends on binder systems for use, and resin is a main component in the binder systems for use.Important parameters is relative molecular mass, functionality, second-order transition temperature, melting viscosity and reactive behavior in the powder coating resin.Yet these parameters are to be mutually related, so resin design is a kind of compromise of influences such as the rheological in powder production technology, the construction application and the mechanical property of coating.The viscosity of resin has influence on extrusion in the production and the coating levelling in the film forming, moistening to granules of pigments during the low-viscosity resin helps to extrude, but the high viscosity resin can promote the dispersion of pigment in resin, therefore has the melting viscosity an of the best.Low-viscosity helps levelling, needs careful design resin but will reach these, considers supporting solidifying agent, and optimizes formulation for coating material.The present invention is by the optimization of formulation for coating material, cooperatively interacting of different auxiliary agents, when using flow agent, added wetting enhancer, finally solved the insufficient phenomenon of paint flow levelling and gloss, can make the high levelling powder coating of high gloss of mirror effect by this prescription, and color is more bright-coloured.The present invention is directed to and indoor and outdoorly all can reach identical effect, not only weathering resistance do not reduced increase on the contrary.
Embodiment
The high levelling powder coating of a kind of high gloss of the present invention, it is applicable to outdoor application, is mainly made by the proportioning raw materials of following weight part: saturated hydroxy polyester resin 50-70 part; Triglycidyl isocyanurate 3.7-5.0 part; Anti-xanthochromia st-yrax 0.01-0.03; Flow agent 0.4-1.0 part; Wetting enhancer 0.5-1.5 part; Filler 10-30 part; Colorant 0.3-20 part.The acid number of described saturated hydroxy polyester resin is 20-45mgKOH/g; It also comprises the activated silica coupling agent, and its weight part is 0.5-2.0 part.
The kind of the composition of polyester, active end group, functionality and relative molecular mass and used solidifying agent and consumption all are important factors of determining the final character of powder coating.TGIC (triglycidyl isocyanurate) coating has outstanding outdoor weatherability, and the use of aliphatic epoxy solidifying agent has reduced the ultraviolet absorption characteristic of coating, thereby has improved weathering resistance.
The high levelling powder coating of a kind of high gloss, it is applicable to indoor application, is mainly made by the proportioning raw materials of following weight part: saturated hydroxy polyester resin 20-40 part; Resins, epoxy 30-50 part; St-yrax 0.01-0.03 part; Flow agent 0.4-1.0 part; Wetting enhancer 0.5-1.5 part; Filler 10-30 part; Colorant 0.3-20 part.
The acid number of described saturated hydroxy polyester resin is 45-85mgKOH/g; It also comprises the activated silica coupling agent, and its weight part is 0.5-2.0 part.
All raw materials are commercially available, wherein saturated hydroxy polyester resin (acid number is 45-85) adopts Shandong Li Bang company to produce, TGIC adopts Niu Tang chemical plant, Changzhou to produce, wetting enhancer adopts the product in Fenghua, the South Sea, Ningbo, and saturated hydroxy polyester resin (acid number is 20-45) adopts and produces association's product.
Production technique: take by weighing filler barium sulfate in proportion earlier and put into a mixing bowl, take by weighing the flow agent butyl polyacrylate of specified amount again, make it to be evenly distributed on the barium sulfate, fully stir, take by weighing the residue component then successively, fully stir again.Emit the material that stirs in a mixing bowl, use three upright twin screw extruders, district's temperature is 120 ℃, and two district's temperature are 100 ℃, melt extrudes and cools off.The use micromill is pulverized, and is 180 purpose steel screen filtrations with the aperture.Use Golden Horse board electrostatic gun, spraying thickness 90-120 micron used the electric heating constant temperature baking-curing 10 minutes then, and solidification value is 200 degree.Test shock-resistantly greater than 30Kgcm, anti-bending is less than 5mm, and sticking power is less than 1 grade, and glossiness is tested greater than 96%.
