Feed for ceramic ferrule forming and preparation method and application thereof
The invention relates to a feed for forming a ceramic ferrule as well as preparation and application of the feed, and belongs to the technical field of ceramic materials. The feed for forming the ceramic ferrule comprises zirconium oxide powder and an additive, wherein the additive comprises polyamide modified phenolic resin, polyvinyl alcohol, polyacrylic acid, oxidized polyethlene wax, microcrystalline wax and an ethylene-vinyl acetate copolymer. According to the invention, by adjusting the additive components in the feed raw material formula and the proportion thereof, the compatibility among the components of the additive is improved, the coating property of the additive on zirconium oxide powder is improved, and the feed prepared by mixing has good fluidity and shape retention; the feed provided by the invention has the characteristics of easiness in molding, small residual stress of a molded blank, small deformation, low molding pressure and the like, and the high-density and high-strength ceramic ferrule is prepared through injection molding, water extraction, glue removal and sintering.
本发明涉及一种陶瓷插芯成型用喂料及其制备和应用，属于陶瓷材料技术领域。所述陶瓷插芯成型用喂料包括氧化锆粉体和添加剂，所述添加剂包括聚酰胺改性酚醛树脂、聚乙烯醇、聚丙烯酸、氧化聚乙烯蜡、微晶石蜡、乙烯‑醋酸乙烯共聚物。本发明通过调节喂料原料配方中的添加剂组分及其配比，提高了添加剂各组分之间的相容性，提高了添加剂对氧化锆粉体的包裹性，通过混炼制备出的喂料具有良好的流动性和保形性；本发明提供的喂料具有易成型、成型坯残余应力小、变形量小、成型压力低等特点，通过注射成型、水萃取、排胶及烧结后制备出高密度和高强度的陶瓷插芯。
