Thermoplastic powder adhesive spray molding ceramic manufacturing method and ceramic
The invention provides a thermoplastic powder adhesive spray molding ceramic manufacturing method and ceramic, and the method comprises the following steps: providing thermoplastic adhesive powder and ceramic powder, and mixing to obtain mixed powder; the preparation method comprises the following steps: dissolving polyvinyl alcohol powder into deionized water, and then adding polyethylene glycol 400, glycerol and an FS-8 fluorocarbon surfactant to obtain a mixed solution; the mixed solution serves as an adhesive, the mixed powder serves as a base material, and ceramic adhesive spraying manufacturing is carried out; the forming cylinder containing the ceramic biscuit is taken out and dried; carrying out secondary curing, and then naturally cooling the ceramic biscuit; carrying out infiltration treatment in an infiltration solution; and baking and drying, and carrying out high-temperature sintering treatment to obtain the thermoplastic powder adhesive spray molding ceramic. The preparation method solves the problems of low biscuit strength, poor high temperature resistance, poor acid and alkali resistance, poor sintering performance and the like in ceramic adhesive spray molding, and can be used for preparing ceramic products with complex structures and high requirements on precision, strength and porosity.
本发明提供一种热塑性粉体粘接剂喷射成型陶瓷制造方法及陶瓷，所述方法包括：提供热塑性粘接剂粉末与陶瓷粉体并混合，得到混合粉末；将聚乙烯醇粉末溶解至去离子水中，再加入聚乙二醇400、丙三醇和FS‑8氟碳表面活性剂，得到混合溶液；将混合溶液作为粘接剂，混合粉末作为基材，进行陶瓷粘接剂喷射制造；将盛有陶瓷素坯的成型缸取出并干燥；二次固化，而后使陶瓷素坯自然冷却；于浸渗液中浸渗处理；烘烤干燥，并高温烧结处理，获得热塑性粉体粘接剂喷射成型陶瓷。本发明解决了陶瓷粘接剂喷射成型中的素坯强度低、抗高温及耐酸碱能力差、烧结性能差等问题，可用于制备复杂结构以及精度、强度、孔隙率要求高的陶瓷产品。
