Abstract

The invention relates to a casting material with high dielectric property. A preparation method comprises the following steps of adding high dielectric filling materials into a bifunctional epoxy system; performing stirring for 20 minutes at 130 DEG C; then, adding a monofunctional epoxy system and nanometer aluminum oxide particles at 95 DEG C; performing stirring for 130 minutes to obtain glue liquid; performing vacuum anti-foaming on the glue liquid; then, adding the materials into a mold; next, performing hot pressing curing to obtain the casting material with high dielectric property. Thecasting material with high dielectric property has excellent flame retardant performance and heat resistant performance, and particularly has excellent dielectric constant.

Description

technical field [0001] The invention belongs to the technical field of electronic composite materials, and in particular relates to a casting material with high dielectric performance. 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 V-0 grade is the exi...
