Abstract

The invention relates to a preparation method of a glue liquor material with a high dielectric property. The preparation method comprises steps as follows: high dielectric filler is added to a bifunctional epoxy system and stirred at 130 DEG C for 20 min, a monofunctional epoxy system and nano alumina particles are added at the temperature of 95 DEG C, the mixture is stirred for 130 min, and a glue liquor is obtained; the solid content of the glue liquor is adjusted to be 60% with propylene glycol methyl ether acetate, and the glue liquor material with the high dielectric property is obtained.The glue liquor material has excellent flame retardance and heat resistance and particularly has the outstanding dielectric constant.

Description

technical field [0001] The invention belongs to the technical field of electronic composite materials, and in particular relates to a preparation method of a glue material with high dielectric properties. Background technique [0002] With the continuous development of science and technology, the application of polymer matrix composites is becoming more and more extensive. At the same time, various application fields also put forward higher requirements for different materials, such as high temperature resistance, ablation resistance, and high dielectric strength. Due to the further demand for size miniaturization and high energy storage density, giant dielectric constant materials have always been a hot spot in the research of modern electronic devices such as capacitors and filters. With the emphasis on flame retardancy, products are required to have flame retardancy. Flame retardancy has grade requirements, which are UL94 V-2, UL94 V-1 and UL94 V-0 grades, of which UL94 ...
