Description

1259173 V. INSTRUCTION DESCRIPTION (1) - [Technical Field to Be Invented by the Invention] The present invention relates to a printing and sintering processing method and a printing material thereof, and in particular to a processing method for printing and sintering applied to a coating technique and Its printed materials. 2. [Prior Art] Traditionally used in the substrate technology, including the common problem of spraying and plating, the particle size of the coating powder has a Millimeter grade to the color, such as color and adhesion, to draw the desired pattern or terracotta glaze. It is too high to draw the high temperature on the substrate to sinter the ceramic glaze, not to mention the new material gold for the outer casing. In addition, the difficulty in production is therefore difficult to draw and time-consuming and process limits such as metal drawing, ceramic glaze or barbecue lacquering. Painting patterns or texts are limited, while conventional particle size micrometers (M i c r ο η) grades are not satisfactory. The effect of the word is relatively good, and the pattern or text needs to be shaped. However, at 100 °C, it is necessary to draw a large amount of ceramic glaze on the substrate, which is far superior to the temperature of, for example, the is alloy, and is maintained at a temperature of 1 ο 〇 or more. Or the painting of the text generally has a surface for about a millimeter on the substrate, and the table is made of ceramic glaze. However, the traditional 1 10000 〇C is a common metal. In view of the above reasons, it is highly desirable to propose a new coating technology to meet the needs of modern coating processing effects and process convenience.

INSTRUCTION DESCRIPTION (2) [Draft] The technical problem to be solved by the present invention is to provide a surface coating processing method and a material thereof which are easy to produce and have good effects. Another technical problem to be solved by the present invention is to provide a surface coating processing method and material thereof which overcomes the particle size limitation of conventional spraying techniques. Another technical problem to be solved by the present invention is to provide a surface coating processing method and material thereof which are low in cost and simple in process.

In order to achieve the above object, the technical means for solving the problem of the present invention employs a printing and sintering processing method comprising the following steps. First, a nano-sized inorganic powder is formed by a grinding method. The inorganic powder is then mixed with an ink to form an ink jet. Next, an ink jet containing a nano-sized inorganic powder is spray-patterned on a substrate by an ink jet printing method (I nk J e t P r i n t i n g). Finally, a sintering process is performed to form a pattern on the substrate. The inorganic powder is preferably a glaze, and the ink must have a high temperature resistance characteristic, and the nano inorganic powder is mixed with the ink to form the above ink jet. In contrast to the effects of the present invention and the prior art, since the printing paste p-junction processing method of the present invention utilizes an inkjet printing method to ink-jet a nanoparticle-containing inorganic powder onto a substrate, it can be relatively low. If the temperature is used for sintering, it is not necessary. For example, traditionally using ceramic glaze to draw patterns or characters on the substrate to sinter up to 1 〇0 〇 °C, not only the process is easy but can be easily applied on the curved surface, the same as 1259173. 3) Since the powder has a nanometer-sized particle size, the surface effect after sintering is good, and there is no problem of the conventional particle size limitation of coating, plating or baking. The above description of the invention and the following embodiments are described in detail as examples and are not limiting. Other equivalent changes or modifications that do not depart from the spirit of the invention are intended to be included within the scope of the invention.

The invention can be implemented by various manufacturing techniques, and only the techniques required to understand the present invention are mentioned herein. Detailed description will be made below in accordance with the accompanying drawings of the present invention, and it is noted that the drawings are in a simple form. In one embodiment of the present invention, the printing and sintering processing method of the present invention forms an ink jet printing method (Ink Jet Print) using an inorganic powder having a nanometer-sized particle diameter to form a pattern on a metal or other substrate.

The above-mentioned granular ink can be made by the grinding method of the grinding method. The mixing of the mixture is specifically carried out in the form of a plane using a jetting machine to form a particle size, and the machine should not be used in a grinding machine. The ink jet diameter of 200 nm is required to form the desired ί-to-temperature ratio to about the printing and printing equipment, and the nanometer-scale inorganic grinding method of the substrate table of 200 nm (or smaller) is preferable, but other can be produced. Nano except. The mechanical polishing method can be carried out by using a milled yarn, which is generally used for forming a nanometer-sized particle size.

The method is simple on the metal substrate, and the subsequent sintering temperature is lower than that of the conventional ceramic glaze at a high temperature of above 100 °C. In addition, the pattern formed by the inkjet printing method can be directly applied to the curved surface, that is, the substrate application surface is not necessarily limited to a plane, the process flexibility is large, the cost is low, and the effect is good.
