Granular nickel-zinc ferrite material and preparation method thereof
The invention discloses a granular nickel-zinc ferrite material and a preparation method thereof. The granular nickel-zinc ferrite material is composed of powder, a binder, a dispersing agent and polyethylene glycol, wherein the powder is composed of ferric oxide, zinc oxide, nickel oxide and copper oxide, and the binder is composed of polyvinyl alcohol, polyvinyl acetate and modified acrylic resin. A green body obtained by carrying out non-isobaric forming on the granular nickel-zinc ferrite material has the advantages of high density uniformity, high plasticity, high strength and the like, and a product obtained by sintering the green body is high in density consistency, high in strength and compact and flat in surface, and can meet high requirements of vehicle-mounted products.
本发明公开了一种镍锌铁氧体颗粒料及其制备方法。本发明的镍锌铁氧体颗粒料由粉料、粘结剂、分散剂和聚乙二醇组成，粉料由氧化铁、氧化锌、氧化镍和氧化铜组成，粘结剂由聚乙烯醇、聚乙酸乙烯酯和改性丙烯酸树脂组成。本发明的镍锌铁氧体颗粒料进行非等压成型得到的生坯具有密度均匀性高、可塑性高、强度高等优点，且烧结得到的制品密度一致性高、强度高、表面致密平整，可以满足车载品的高要求。
