Abstract

The invention provides a method for improving the mechanical property of a ceramic polymer composite material, and the method comprises the following steps: carrying out plasticizing molding on corundum-type alumina particles and PPS engineering resin to obtain a composite material blank, and carrying out heat treatment to obtain the ceramic polymer composite material. The invention provides a material heat treatment method which is used for carrying out heat treatment on a high-strength ceramic polymer composite material containing ultrahigh-proportion ceramic powder and aims at eliminating static friction force and static pressure stored in the material forming process. The material has the advantages of ceramic and high polymer materials, has the characteristics of good mechanical strength, high thermal conductivity, good high temperature resistance, excellent processability and the like, and is very suitable for being applied to power PCBs (Printed Circuit Boards).

Description

technical field [0001] The invention relates to the field of new materials, in particular to a method for preparing a ceramic polymer composite material. Background technique [0002] The statements in this section only provide background information related to the present disclosure and may not constitute prior art. [0003] Printed Circuit Board (PCB), as a basic and important part of the modern electronics industry, is widely used in almost all electronic devices. [0004] At present, printed circuit boards are mainly prepared by etching. The main principle is to use copper clad laminates as raw materials. By using oxidative etching solution, under the protection of photosensitive resin, the copper foil of unnecessary parts will be removed according to the requirements of circuit design drawings. Etched and removed to form the basic circuit. Multiple such circuits are superimposed, and the substrates of epoxy materials are laminated together to form a multi-layer board ...
