本発明は、乾式静電塗装に用いられるフリット組成物の
着色方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for coloring a frit composition used in dry electrostatic coating.

脂を融着させて道っていた。(Prior art) Conventionally, the method for coloring a frit composition used in dry electrostatic coating involves adding a pigment, such as a coloring metal or its oxide, into the frit raw material in advance, mixing and melting the resulting frit, and then pulverizing the resulting frit. The resin was fused to the colored frit powder obtained by the process.

困難であった。(Problems to be Solved by the Present Invention) In the case of frit used in dry electrostatic coating, simply mixing the pigment with the frit powder and the fii[powder] will not solve the problem.
Because the particle size and physical properties of the frit powder, resin powder, and pigment are different, the oversprayed recovered powder and the new powder differ not only in color tone but also in composition. Therefore, when the overspray product is recycled and used, it is necessary to produce a uniform final enameled product. It was difficult to obtain.

であった。本発明はこうした問題に鑑み、最終琺瑯製品
の色感を精密に制御し得る事を目的としている。Furthermore, since the pigments commonly used are colored metals or their oxides, it may be difficult to apply static electricity. Therefore, a resin is fused to a colored frit that has been prepared by adding and melting a pigment into the frit and then using it as a frit composition. Therefore, if the color tone of the final enamel product differs from the desired one after coating and baking the previously prepared frit composition, the colored frit must be recreated, making it impossible to make subtle color tone adjustments. there were. In view of these problems, the present invention aims to precisely control the color appearance of the final enamel product.

Furthermore, if necessary, the stirred media mill is equipped with a jacket and heated and cooled to maintain an appropriate temperature at all times to promote the fusion of the resin powder and pigment to the frit particles.

を効率良く得ることが出来る。(Function) As a method for coloring the frit composition of the present invention, a grinding medium with a diameter of several meters or less is stirred with strong force using a stirring medium mill, and strong shearing and compressive force is applied to each particle of the frit. By acting on the particles to ensure dispersion, mixing, and kneading of the frit powder, resin powder, and pigment, the resin powder and pigment can be fused to the surface of the frit particles and colored in any desired color tone. In addition, heating from the mill jacket,
By cooling, a more uniform product can be efficiently obtained by constantly maintaining a temperature suitable for fusing the resin powder and pigment to the frit particles.

Another advantage is that the color tone of the final enamel product, which tends to change depending on firing conditions, can be precisely adjusted and controlled. In other words, according to the present invention, it is possible to freely add any pigment to the frit powder afterwards, so when mixing the color, check the color tone using a test sample and if there is a problem, finely adjust the proportion of the necessary pigment, It is possible to easily obtain a final enamel product with a color tone of .
