Preparation method of LTCC (Low Temperature Co-Fired Ceramic) green tape slurry
The invention discloses a preparation method ofLTCC (Low Temperature Co-Fired Ceramic) green tape slurry. The method comprises the following steps: adding an organic solvent, a dispersing agent and glass ceramic mixed powder into a ball milling tank, and enabling the dosage of the organic solvent to submerge the glass ceramic mixed powder; placing the ball milling tank on a horizontal roller mill, and performing rotary rolling for 120-150 min at the rotating speed of 60 r/min; adding a surfactant and a thixotropic agent into the ball milling tank, and performing rotary rolling for 400-500 min at the rotating speed of 60 r/min; adding a binder and a plasticizer into the ball milling tank, and carrying out rotary rolling at a rotating speed of 60r/min for 5-7h to obtain uniformly mixed slurry; and pouring out the slurry, and defoaming in a vacuum cavity at the vacuum degree of a 635mm mercury column for 10-20 minutes to obtain LTCC (Low Temperature Co-Fired Ceramic) green tape slurry. The invention aims to provide the preparation method of the LTCC green tape slurry. The viscosity of the LTCC green tape slurry obtained by the method is good; the LTCC green tape prepared from the LTCC green tape slurry is low in co-firing temperature, high in dielectric constant and small in signal attenuation, and meets the high requirement for LTCC in the 5G mobile communication technology.
本发明公开了一种LTCC生瓷带浆料制备方法，包括以下步骤：向球磨罐中加入有机溶剂、分散剂和玻璃陶瓷混合粉料，机溶剂用量应淹没玻璃陶瓷混合粉料；将球磨罐置于卧式辊磨机上，以60r/min转速旋辗120‑‑150min；向球磨罐中加入表面活性剂和触变剂，再以60r/min转速旋辗400‑‑500min；向球磨罐中加入粘结剂和增塑剂，再以60r/min转速旋辗5‑‑7h，得到混合均匀的浆料；倒出浆料，在1个真空腔体内以635mm汞柱的真空度脱泡10‑‑20min，获得LTCC生瓷带浆料；本发明的目的在于提供一种LTCC生瓷带浆料制备方法，通过本方法获得的LTCC生瓷带浆料粘度好；通过本LTCC生瓷带浆料制备LTCC生瓷带共烧温度低，介电常数高，信号衰减小，满足5G移动通信技术中对LTCC的高要求。
