Ceramic rear cover and preparation method
The invention provides a ceramic rear cover and a preparation method. According to the textured ceramic mobile phone rear cover, a casting membrane is obtained through a tape-casting process, then thecasting membrane is laminated, vacuum-packaged and subjected to warm isostatic pressing to obtain a textured ceramic green body, the textured ceramic green body is degreased and sintered to obtain atextured ceramic blank, and the textured ceramic blank is stable in surface texture pattern and color, not prone to discoloration and resistant to scratching. According to the invention, a LOGO is manufactured by using a forming mold with a LOGO forming cavity, one-time molding of textures and the LOGO is realized, and the texture surface is of an intaglio character structure, the LOGO surface isof a relief character structure, and the problem that the appearance effect is affected due to layering, falling, unfilled corners and other defects generated in the demolding, polishing and other processes of the LOGO due to adhesion of the green body and the mold during demolding is solved through the addition of the texture dielectric slice. The development cost of the mold is saved, the development period of a new product is shortened, and the machining efficiency is effectively improved.
本发明提供一种陶瓷后盖及制备方法，本发明的纹理陶瓷手机后盖采用流延工艺得到流延膜片，再将流延膜片叠层、真空包装后经温等静压成型得到具有纹理的陶瓷生坯，经脱脂烧结后得到纹理陶瓷毛坯，而且表面纹理图案及色彩稳定，不易变色，耐刮擦。本发明利用具有LOGO成型腔的成型模具制作LOGO，以实现纹理和LOGO的一次成型，且纹理面为阴文结构，LOGO面为阳文结构，纹理介质片的加入解决了脱模时生坯与模具粘连，造成LOGO处在脱模、抛光等过程产生的分层、脱落、缺角等缺陷，从而影响外观效果的问题。节约了模具的开发成本，缩短了新产品的开发周期，并有效提高加工效率。
