Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an adhesive for molding electronic ceramics and a preparation method thereof. Background technique [0002] Electronic ceramics refer to ceramic materials with stable mechanical properties, good corrosion resistance and aging properties, especially ceramic materials that can be used in electronics, communications, automobiles, machinery, textiles and other industries because of their excellent electrical properties. For example, piezoelectric materials can generate electric fields due to mechanical deformation, and can also generate mechanical deformation due to the action of electric fields. This inherent electromechanical coupling effect makes piezoelectric materials widely used in engineering, such as drives, energy converters, sensors, frequency control devices, etc., and the new generation of piezoelectric materials also has conditioned reflection and The abili...
