Preparation method of ceramic slurry, ceramic slurry, coated diaphragm and application
The invention discloses a preparation method of ceramic slurry, the ceramic slurry, a coated diaphragm and application of the ceramic slurry, a quaternized silane coupling agent and a surfactant are used for sequentially exchanging ions with porous ceramic, and a core-shell structure is formed by the porous nano ceramic and a flexible long chain, so that the problem that the porous nano ceramic with small particle size is difficult to disperse is solved; meanwhile, the network structure formed by staggering the flexible long chains can well hinder sedimentation of large-particle-size micron ceramic particles. The problem that existing ceramic slurry for coating the diaphragm is low in stability is solved, and the prepared ceramic slurry has good dispersion stability and high solid content flowability.
本申请公开了一种陶瓷浆料的制备方法及陶瓷浆料、涂覆隔膜及应用，通过使用季铵化的硅烷偶联剂、表面活性剂依次与多孔陶瓷离子交换，以多孔纳米陶瓷和柔性长链形成的核壳结构，改善小粒径的多孔纳米陶瓷难分散的问题，同时柔性长链交错形成的网络结构可以很好得阻碍大粒径的微米陶瓷颗粒沉降。本申请解决现有涂覆隔膜的陶瓷浆料稳定性低的问题，由此制得的陶瓷浆料具有较好的分散稳定性和高固含量可流动性。
