High-energy-storage ceramic capacitor dielectric material and preparation process thereof
The invention discloses a high-energy-storage ceramic capacitor dielectric material and a preparation process thereof. The process includes the steps that glass powder is added into polyurethane emulsion, polyurethane particles are attached to the surface of the glass powder after high-speed stirring treatment, then nano ceramic powder subjected to surface treatment is added into the glass powder,filtering is conducted after high-speed stirring and mixing, and the high-energy-storage ceramic capacitor dielectric material is obtained; drying the solid-phase product for the first time to obtaina structure in which polyurethane is used as an adhesive and glass powder and nano ceramic powder are adhered to each other, uniformly dispersing the glass powder and the nano ceramic powder by usingpolyurethane emulsion as a dispersion system, then avoiding agglomeration through ball milling, and roasting the ball-milled product at high temperature to obtain the nano ceramic powder/polyurethanecomposite material. The preparation method comprises the following steps: dissolving the nano ceramic powder in a solvent to decompose a polyurethane component in the nano ceramic powder, and repeatedly roasting and ball-milling to repeatedly form and crush a glass structure coated on the surface of the nano ceramic powder formed by roasting, thereby enhancing the diameter of the particles and the uniformity and coating integrity of the glass layer coated on the surface of the nano ceramic powder.
本发明公开了一种高储能陶瓷电容器介质材料及其制备工艺，该工艺首先将玻璃粉加入聚氨酯乳液中，在经高速搅拌处理后，使聚氨酯颗粒附着在玻璃粉的表面，然后再向其中加入经过表面处理的纳米陶瓷粉料，高速搅拌混合后，过滤，并对固相产物进行第一次烘干，从而得到以聚氨酯作为胶粘剂，玻璃粉与纳米陶瓷粉料相互粘连的结构，利用聚氨酯乳液作为分散体系，使玻璃粉与纳米陶瓷粉均匀分散，然后再通过球磨避免聚团，并将球磨后的产品进行高温焙烧，使其中的聚氨酯成分分解，然后再通过反复多次的焙烧与球磨，使焙烧成型的纳米陶瓷粉表面包覆玻璃结构反复的形成与破碎，提升粒子的直径以及纳米陶瓷粉表面包覆的玻璃层的均匀性与包覆完整性。
