Binder composition, microwave dielectric ceramic granules, ceramic and ceramic filter
The invention relates to a binder composition for microwave dielectric ceramic injection molding, the composition comprises a main binder, a skeleton binder, a lubricant and a plasticizer, the main binder comprises polyformaldehyde, and the melt index of the polyformaldehyde under the condition of 190 DEG C/2.16 kg is 120-250 g/10 min, preferably 150-220 g/10 min. According to the binder composition provided by the invention, the polyformaldehyde is used as a main binder, and the polyformaldehyde has a relatively high melt index, so that the binder composition can still enable the microwave dielectric ceramic granules to have relatively high flowability under the condition of relatively high addition amount; a green body obtained by injection molding of the microwave dielectric ceramic granules is uniform in texture and high in consistency, so that the quality stability of a microwave dielectric ceramic product can be remarkably improved.
本公开涉及一种用于微波介质陶瓷注射成型的粘结剂组合物，该组合物包括主粘结剂、骨架粘结剂、润滑剂和增塑剂，其中，所述主粘结剂包括聚甲醛，所述聚甲醛在190℃/2.16kg条件下的熔融指数为120～250g/10min，优选为150～220g/10min。本公开提供的粘结剂组合物中以聚甲醛为主粘结剂，该聚甲醛具有较高的熔融指数，因此，该粘结剂组合物能够在添加量较高的情况下仍然使得微波介质陶瓷颗粒料具有较高的流动性，利用这样的微波介质陶瓷颗粒料注射成型得到的生胚体的质地均匀、一致性高，这能够显著提升微波介质陶瓷产品的质量稳定性。
