Problems solved by technology

Simple resins can no longer meet the application of copper clad laminates. Therefore, the use of composite technology not only integrates the advantages of organic and inorganic materials, but also matches different organic components. It is hopeful to prepare copper clad laminates that meet industrial applications.

Abstract

The invention relates to an electronic material and a preparation method thereof. The preparation method comprises the following steps: mesoporous silica is modified firstly, then epoxy with monofunctional groups and epoxy with bifunctional groups are prepared, and a glue solution is obtained by mixing; the glue solution, a reinforcing material and metal foil are subjected to hot-press molding, and the electronic material can be obtained. The electronic material has the excellent flame retardance and heat resistance, and requirements for development and application of the electronic material are met.

Description

technical field [0001] The invention belongs to the technical field of electronic composite materials, and in particular relates to an electronic material and a preparation method thereof. The obtained product can be used in the fields of aerospace, signal transmission, and electronic communication. Background technique [0002] The main performance of the PCB board, especially the signal transmission performance, is only determined by the CCL, and the performance of the CCL has a great relationship with the resin matrix. 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. Especially in cutting-edge science and technology fields such as the aerospace industry, the performance requirements of materials are more stringent. For example, they require composite materials to have high sp...
