Problems solved by technology

However, objects with a hard surface such as ceramics, glass, metal surfaces and hard plastics with low ink absorption generally have higher requirements for the printing gap value. The thickness of the pattern layer obtained by this process is only 30-100 Micron, there are rough details in printing, prone to blurred graphics and line deformation, printed matter is easy to be dirty and the surface is prone to defects such as bubbles
[0003] Ceramic surface decoration processes generally include printing and physical vapor deposition (CVD), but these processes have high requirements on the smoothness of the ceramic surface, and the pattern is on the ceramic surface after surface treatment, which has poor abrasion resistance and no layered appearance.
In addition, because the ink used for printing contains a certain amount of solvent, the shrinkage rate after drying is large, and it is not suitable for printing thick films. After printing or physical vapor deposition to form patterns, mechanical processing cannot be performed, and the patterns are easy to wear and fade.

preparation example Construction

[0028] The present invention also provides a preparation method of a ceramic composite material, wherein the preparation method comprises: filling a pattern decoration material on a ceramic base material with a pattern groove, heating the pattern decoration material to solidify the surface of the pattern groove Polished.

[0029] According to the preparation method of the ceramic composite material of the present invention, the ceramic composite material can be prepared according to the following procedures. According to the desired pattern, set a pattern groove of a specific depth on the zirconia ceramic substrate, mix the thermosetting resin and the curing agent, add a specified amount of metal powder and / or metal oxide powder, and mix the obtained slurry Fill it into the pattern groove on the ceramic substrate, let it stand for a period of time to discharge the air bubbles in the slurry, place the filled ceramic substrate in an oven, keep it at the curing temperature for a ...

Embodiment 1

[0034] On a zirconia ceramic sheet with a thickness of 1.5mm, a pattern groove with a depth of 0.6mm is set, and 100 parts by weight of epoxy resin E-51 (purchased from Taizhou Plastic Industry Co., Ltd.), 40 parts by weight of methylhexahydro After phthalic anhydride and 1 weight part of dimethylimidazole are mixed evenly, add 400 parts by weight of silver powder (purchased from Guiyan Platinum Industry Co., Ltd., particle size is 0.1-10 μm) with an average particle diameter of 1 μm, after stirring evenly, put The resulting pattern decoration paste was allowed to stand for 10 minutes. Fill the pattern decoration slurry into the pattern groove on the zirconia ceramic sheet, place it in an oven after scraping, and keep it warm at 120°C for 4 hours to solidify the pattern decoration slurry, cool to room temperature (25°C), and use The polishing machine performs surface polishing on the ceramic sheet. A ceramic composite material 1 was obtained.

Embodiment 2

[0036] A pattern groove with a depth of 0.6 mm is set on a zirconia ceramic sheet with a thickness of 1.5 mm, and 100 parts by weight of epoxy resin E-51 (purchased from Taizhou Plastic Industry Co., Ltd.), 5 parts by weight of methylhexahydro After the phthalic anhydride is mixed evenly, add 500 parts by weight of nickel powder (purchased from Changsha Liyou Metal Material Co., Ltd., particle size is 0.1-10 μm) with an average particle diameter of 5 μm. minute. Fill the pattern decoration slurry into the pattern groove on the zirconia ceramic sheet, place it in an oven after scraping, and keep it warm at 120°C for 4 hours to solidify the pattern decoration slurry, cool to room temperature (25°C), and use The polishing machine performs surface polishing on the ceramic sheet.

Abstract

The invention provides a ceramic composite material. The ceramic composite material comprises a ceramic substrate and a pattern decoration filling material. The ceramic substrate is provided with pattern grooves. The pattern grooves are filled with the pattern decoration filling material. The invention also provides a preparation method of the ceramic composite material. The preparation method comprises filling the pattern grooves of the ceramic substrate with the pattern decoration filling material, heating to cure the pattern decoration filling material and polishing the surfaces of the pattern grooves. The ceramic composite material can form clear patterns and the patterns have stereoscopic sensation and good wear resistance and can be further subjected to machining.

Description

technical field [0001] The invention relates to the field of ceramic surface decoration, in particular to a ceramic composite material and a preparation method thereof. Background technique [0002] Screen printing technology is widely used in China to decorate pottery and other items. Screen printing, also known as screen printing or screen printing, belongs to stencil printing. After the substrate is placed under the screen, ink is applied to the screen. Finally, the ink is beaten and squeezed through the holes of the stencil to the surface of the substrate beneath the screen by pulling the squeegee over the screen. However, objects with a hard surface such as ceramics, glass, metal surfaces and hard plastics with low ink absorption generally have higher requirements for the printing gap value. The thickness of the pattern layer obtained by this process is only 30-100 Micron, there are defects such as rough printing of details, blurred graphics and line deformation, easy...
