Preparation process for preparing ceramic mobile phone rear cover through gel casting
The invention discloses a preparation process for preparing a ceramic mobile phone rear cover by gel casting. The preparation process comprises the following steps: preparing raw materials: modified zirconia ceramic powder, a monomer, a cross-linking agent, a dispersing agent, a sintering aid, an initiator, a catalyst and a solvent; putting the modified the zirconia ceramic powder, the monomer, the cross-linking agent, the dispersing agent and the solvent into a ball mill for ball milling to obtain mixed slurry; adding the initiator and the catalyst into the mixed slurry, and carrying out vacuum defoaming to obtain ceramic slurry; injecting the ceramic slurry into a mold, standing, demolding and drying to obtain a ceramic mobile phone rear cover green body; and placing the ceramic mobile phone rear cover green body in a punching machine to be punched and finally coated with a hardened layer; according to the preparation process, the ceramic rear cover is prepared through gel casting sothat the prepared ceramic rear cover is more uniform, and the strength of the prepared ceramic rear cover is improved by adopting the modified zirconium oxide ceramic powder; the preparation processis simplified, the efficiency is improved, and the preparation process has good market promotion value.
本发明公开了一种凝胶注模制备陶瓷手机后盖的制备工艺，其包括以下步骤：原料准备：改性氧化锆陶瓷粉体、单体、交联剂、分散剂、烧结助剂、引发剂、催化剂、溶剂；将改性氧化锆陶瓷粉体、单体、交联剂、分散剂、溶剂置于球磨机中进行球磨得到混合浆料；向上述的混合浆料中加入引发剂、催化剂，进行真空脱泡，得到陶瓷浆料；陶瓷浆料注入模具内并静置、脱模、干燥，得到陶瓷手机后盖生坯；陶瓷手机后盖生坯置于冲压机中进行冲压，最后涂布硬化层；本发明通过凝胶注模制备陶瓷后盖，使得制备的陶瓷后盖更均匀，通过采用改性氧化锆陶瓷粉体的使用有助于增加制备陶瓷后盖的强度；本发明简化了制备工艺，提高了效率，有着良好的市场推广价值。
