Description

Ink for ceramic surface printing and ceramic surface printing method using the same

The present invention relates to a ceramic surface printing ink and a ceramic surface printing method using the same, and more particularly, by printing a ceramic surface by using a ceramic surface printing ink made of a polyester-modified silicone resin, a heat-resistant pigment, etc. The present invention relates to a ceramic surface printing ink and a ceramic surface printing method using the same, which can be printed as well as have excellent adhesion to a printing film.

In general, ceramic products that are applied to various fields such as daily necessities, electronic components, etc., have a labeling or logo on the surface thereof.

In general, the decorative method for marking a logo on the ceramic surface is repeated 2 to 3 times by coating the ceramic ink by the screen printing method, as known in the Republic of Korea Patent Publication No. 10-0302113, and then heating the ceramic coating film After dissolving, the relief of ceramic products is decorated, or before printing, the surface of the ceramic material is processed by uneven method such as casting, laser processing, extrusion molding, etc., and then coating ceramic paint thereon. Labeling or logos are indicated.

However, the above methods are complicated and expensive, and in particular, there is a problem such as causing quality damage of the coated film and limiting color expression.

In particular, when a coating material of an organic modified silicone resin coating material is coated on the surface of a ceramic product, the coating film formed on the ceramic surface is formed of C ₁ to C ₄ , such as methyl, ethyl, propyl, butyl, etc. Low surface activity is formed by the alkyl group, and low surface energy is formed on the surface of the coating film due to floating and adsorption on the surface of the coating film of silane oligomers having low surface energy formed during curing of the film of the coating film.

Accordingly, the surface of the coating film cured by the above methods has a water contact angle of about 70 ° or more, resulting in a low surface energy, thereby degrading wettability of the ink and adhesion after curing.

In addition to the above problems, due to contamination of other organic matter and adsorption of moisture contained in the air, the coating film surface of the organic binder ink causes wettability and deterioration of adhesion.

It is not adhered properly to the wetted area, the bond strength with the coating film is lowered, even when using various kinds of inks, the ink did not have sufficient adhesion even after the dry curing, and this did not apply commercially.

Therefore, the introduction of a printing method using a high heat resistant ink which can be applied at a simpler process and at a lower cost has been required. Specifically, a simple pretreatment method capable of giving good wettability and adhesion and a good wettability on the surface of the coating film after pretreatment There is an urgent need for the development of high heat resistant inks capable of imparting adhesion.

However, due to the properties of the surface of the ceramic coating film, only degreasing or cleaning with a solvent or detergent aqueous solution generally used, sufficiently high coating surface for imparting good wettability and adhesion of the general ceramic ink or high heat-resistant printing ink. Energy (water contact angle of 30 ° or less) could not be obtained, and cleaning with a strong alkali solution of pH 13 or higher, such as special chemicals, or fluorine-containing solvents or chemicals could seriously damage the coating surface of the ceramic coating film. In addition, the process was difficult to apply commercialization was a problem.

Therefore, the present invention can be simply printed on the ceramic surface using the ink for printing the ceramic surface made of polyester modified silicone resin, heat-resistant pigment, etc. as a means for printing the ceramic surface as a solution for solving the problems as described above. In addition, the present invention relates to an ink for printing a ceramic surface and a method of printing a ceramic surface using the same, which can impart excellent adhesion to a printing film.
