Description
Technical Field
The invention relates to a coating method and a device of metal powder coating, which are suitable for coating application of various powder coatings on various coating production equipment, in particular to coating application of an automatic coating production line.
Background
With the enhancement of global Environmental protection consciousness, the powder coating has the advantages of economy, high efficiency, Environmental protection, Energy Saving and the like (commonly called 4E: Economical, effective, Environmental, Energy Saving), and is developed rapidly, and the powder coating completely replaces liquid coating in many fields. After the 90 s of the 20 th century, powder coatings have been developed in great numbers with the advent of decorative powders. The world powder coating market is rapidly increasing at a rate of 15% to 20% per year. Powder coatings have become an important mainstay in the coatings industry.
The powder coating is a powdery substance prepared by the procedures of high-temperature extrusion and pulverization of raw materials comprising resin, pigment, filler, additive and the like. The most common application method for powder coatings is to spray a fluidized powder using an electrostatic spray gun, where the powder is charged in an ionized layer between the spray gun and the substrate and is attracted to the substrate under the drive of a voltage. And baking the base material adsorbing the powder at high temperature to solidify the powder to form a coating.
The production, coating and application technologies of common powder coatings are well developed, but the metal powder coating technology is still to be perfected. The prior art can not fully meet the production requirement. The metal powder coating is not as stable and reliable as a metal liquid coating, and mainly shows that the metal powder coating is difficult to produce stably, color difference is difficult to avoid during coating, the recycled powder cannot be used, and the like. Moreover, the higher the metallic pigment content, the more problematic.
The reason why the metallic powder coating is difficult to produce is because the metallic pigment and the powder have different charging properties, different compatibility and different geometric shapes. Metallic powder coatings are produced by mixing metallic pigments with powders that have been extruded and comminuted, the metallic pigments not being intimately encapsulated by resin as in liquid coatings but being present alone. When spraying, the metal pigment has different charged performance and different powder spraying capability, so that color difference occurs. In order to improve the powdering condition of the metal pigment, people invent a binding technology, namely, the metal pigment and the powder are adhered by stirring at a high speed to generate heat, so that the difference between the electrification property and the geometric shape of the metal pigment and the powder is relieved. The coating stability of the metal powder coating treated by the binding technology is greatly improved, so that the production of the metal powder coating becomes operable. On the other hand, metal pigment suppliers carry out inorganic or organic coating on the metal pigment, so that the chargeability and the compatibility with resin of the metal pigment are improved, and the metal powder coating is greatly helped to improve the coating stability. However, neither the binding technique nor the metal pigment wrapping technique can completely solve the series problems of metal powder coating, and the metal powder coating is always a difficult task in coating work.
How to solve the series coating problem of the existing metal powder coating is a very urgent technical problem to the whole powder coating boundary. Because the metallic color cannot be coated, the coating of many metallic colors still has to be coated by liquid which is highly polluted and costly. If the problem of color difference of the metal powder coating and the problem that the recycled powder cannot be used can be solved, the method has very positive significance to the powder coating industry.
The most important problem of metal powder coating is the color difference caused by using recycled powder. In fact, whether the metallic pigment is coated or bound, the color of the coating sprayed under certain coating process conditions should be the same. Even if the spraying process fluctuates, the color of the sprayed coating is basically unchanged as long as the coated metal pigment is adopted and the effective binding treatment is carried out. The problem is that the proportion of the metal pigment of the recovered powder is greatly different from that of the original powder in many cases, and the color difference can occur when the recovered powder is mixed into the original powder for spraying. If the content of the metallic pigment is high, the metallic pigment content of the recovered powder is often too high, and in severe cases, the coating does not form a film.
Disclosure of Invention
The invention mainly aims to provide a novel coating method and a novel coating device for metal powder coating, which can solve the problem of color difference of recovered powder, greatly improve the coating stability and reduce the color difference.
The technical means of the invention is as follows: a method for coating metallic powder paint features that the waste powder in the process of spraying paint is recovered and reused, and the paint used in coating the bottom layer is first used and then the surface layer is coated.
When the recovered waste powder is mixed with the new powder for use, the recovered waste powder is directly and simply mixed with the new powder without special proportion calculation and stirring for direct use.
A coating device for metal powder coating comprises a plurality of spray guns, wherein the spray guns are connected with a fluidizing barrel for supplying powder, the fluidizing barrel is divided into a first fluidizing barrel and a second fluidizing barrel, wherein the first fluidizing barrel only contains new powder, and the second fluidizing barrel only contains the new powder and recovers waste powder; the spray gun is divided into a bottom spray gun for spraying the bottom layer and a surface spray gun for spraying the surface layer, the first fluidization barrel is connected with the surface spray gun, and the second fluidization barrel is connected with the bottom spray gun

Detailed Description
Theoretically, the same process coating should result in the same coating color. The problem of color difference of the recovered powder is solved to avoid the color difference caused by the metal content difference of the recovered powder during coating. That is, if only new powder is used for coating, the color difference is easily controlled. It is noted that automatic coating lines often use a plurality of spray guns to coat, and the powder sprayed from the front spray gun is absorbed and then the powder sprayed from the rear spray gun is covered on the top. If the first few guns use powder mixed with recycled powder and the last one or two (one or two) guns use only fresh powder, it is possible to ensure that the colour of the coating surface is uniform.
according to the above idea, a single fluidization tub is provided for supplying powder exclusively to the last or two spray guns, while the recycled powder is poured into the original fluidization tub for supplying powder exclusively to the front several spray guns. The powder blended with the recovery powder, although having a certain color difference, does not affect the color of the surface because it is not on the surface.
The new powder fluidizing barrel can be independently arranged or integrated with the original fluidizing barrel, the part for spraying the new powder is only added with the new powder, and the other part is added with the recovered powder and is supplied to a plurality of guns in front.
The invention relates to a coating method of metal powder coating, which is characterized in that waste powder in the coating spraying process needs to be recycled, and the method is characterized in that coating is firstly used for coating a bottom layer part and then used for coating a surface layer part, wherein the coating for coating the bottom layer part adopts the recycled waste powder and the new powder to be mixed for use, and the coating for coating the surface layer part adopts the new powder completely without adopting the recycled waste powder.
When the recovered waste powder is mixed with the new powder for use, the recovered waste powder is directly and simply mixed with the new powder without special proportion calculation and stirring for direct use. When a fluidizing barrel is adopted originally, waste powder needs to be subjected to strict calculation, mixed in proportion and stirred for a long time, and then the waste powder can be used, so that the whole recycling process is long, the whole coating process is long in time except that the spraying color is influenced, and the working efficiency is relatively low. After the method is adopted, the recovered waste powder is directly mixed with the waste powder simply for direct use without repeated mixing steps, so that the overall smoothness of coating is greatly improved, the working efficiency is improved, the labor intensity of workers is reduced, and the workers do not need to work in a harmful dust space for a long time.
as shown in fig. 1, the present invention provides a coating apparatus for metal powder coating, which has a plurality of spray guns (more than two), wherein the spray guns are connected with a fluidizing barrel for supplying powder, the fluidizing barrel is divided into a first fluidizing barrel 8 and a second fluidizing barrel 9, wherein the second fluidizing barrel 9 only contains new powder, and the first fluidizing barrel 8 contains new powder and recovers waste powder;
The spray gun is divided into a bottom layer spray gun for spraying a bottom layer and a surface layer spray gun for spraying a surface layer, the second fluidization barrel 9 is connected with the surface layer spray gun, and the first fluidization barrel 8 is connected with the bottom layer spray gun.
In this embodiment, the left side and the right side are respectively provided with four spray guns, taking the left side as an example, the first spray gun 4, the second spray gun 5, the third spray gun 6 and the fourth spray gun 7 are arranged in sequence from top to bottom, the same on the right side is not described herein again, and the spray guns are arranged on the spray gun support 2. The construction of the lance here is similar to the prior art construction.
The section bar 1 moves from bottom to top and passes through a fourth spray gun 7, a third spray gun 6, a second spray gun 5 and a first spray gun 4 in sequence, in the embodiment, the fourth spray gun 7 and the third spray gun 6 are defined as bottom layer spray guns, the second spray gun 5 and the first spray gun 4 are defined as surface layer spray guns, the second fluidizing barrel 9 is connected with the first spray gun 4 and the second spray gun 5, and the first fluidizing barrel 8 is connected with the third spray gun 6 and the fourth spray gun 7.
In addition, the definition of the surface layer spray gun and the bottom layer spray gun can be adjusted according to requirements, for example, three spray guns can be used as the bottom layer spray gun, and one spray gun is used as the surface layer spray gun. If the number of the spray guns is large, the spray guns can be flexibly adjusted, for example, ten spray guns are adopted, three surface spray guns, seven bottom spray guns or two surface spray guns and eight bottom spray guns are adopted.
If the amount of the coating sprayed on the surface layer is 5-50% by mass of the amount of the powder to be sprayed, and the amount of the coating sprayed on the lower layer is 50-95% by mass of the powder coating mixed with the recovered waste powder, it is more preferable that the amount of the coating sprayed on the surface layer is 10-30% by mass of the new powder and the amount of the coating sprayed on the lower layer is 70-90% by mass of the powder coating mixed with the recovered waste powder, because the surface layer is too thin and the color difference may be problematic, and also from the viewpoint of cost.
Generally, the metal powder coating contains 0.01 to 30 mass% of a metal pigment (excluding metal pigments). The metal powder paint comprises aluminum powder pigment, pearlescent pigment and other metal pigment. The coating comprises polyester, polyurethane, epoxy, acrylic acid, fluorocarbon coating and the like. Both thermosetting and thermoplastic powder coatings are included.
The following are specific examples.
Example one
The coating equipment is an automatic spraying assembly line, two surfaces in a spraying room are coated, each surface is respectively provided with ten golden horse spray guns which are divided into an upper row and a lower row, and five golden horse spray guns are respectively arranged. The coating workpiece is various aluminum profiles, and the coating linear speed is 5 m/min. The powder coating is silver polyester powder coating with the mass fraction of 6 percent of aluminum powder content.
In the metal powder coating process, powder suction pipes of two spray guns (one spray gun at the upper part and the other spray gun at the last time) of ten spray guns at one side are inserted into a single fluidizing barrel which is called a new powder fluidizing barrel. The recycled powder is not used in the new powder fluidization barrel, and only new powder is added; in addition 8, the powder suction pipe of the spray gun is inserted into the original fluidizing barrel, and the fluidizing barrel receives all the recovered powder coating and continuously adds new powder. The other ten spray guns and powder supplies are also treated as such.
After the method is adopted, the metal color of the coating can be kept uniform in the spraying process for several hours, and the color difference is small.
The color of the product is relatively normal in the first few minutes of production, but changes with the increase in recovered powder, as compared to production without the method.
Example two
As in the first embodiment, the air suction pipes of the last four spray guns (two spray guns above and below) are inserted into a new powder fluidization barrel, and only new powder is added into the fluidization barrel; the other six spray guns insert the powder suction pipe into the original recovered powder fluidization barrel, and the fluidization barrel receives all the recovered powder and adds new powder. The other ten spray guns and powder supplies are also treated as such.
The spraying is carried out for several hours, the metal color of the coating can be kept uniform, and the color difference is small.
Example three example thirteen
In the following schemes, the coating process according to scheme two is adopted. No matter the content of the metal pigment is high or low, the color of the coated product is stable, and the recovered powder can be normally used. Before the process of the invention is adopted, the color difference of the metal powder coating is usually very large, especially the powder coating with high metal content, and the recycled powder can not be used frequently because of the influence on the color difference, the surface coarsening and the like.
Example fourteen
The coating equipment adopts a manual spray gun, and an aluminum veneer or a large aluminum profile is coated in a small spray room. The powder coating adopts PVDF fluorocarbon powder coating with golden pearl content and 4.5 percent of mass percentage. The powder doped with the recovered powder is sprayed, after about three-quarters of the thickness of the powder is sprayed, another spray gun using only new powder is replaced, and a layer of powder is sprayed thinly on the surface. The coating result shows that the surface color of the metal coating is stable, and the larger color difference is avoided.
