Abstract

The invention relates to a heat-conducting electronic material composition which is obtained by mixing N,N'-carbonyldimidazole, tetra-functional epoxy resin, tri-n-butylamine, indoline-2,3-diketone, 2,6-di(4-aminophenoxy) cyanobenzene, a filler, cycloaliphatic epoxide resin, sodium triacetate and acraldehyde. Raw materials in a preparation method disclosed by the invention are wide in source, and the preparation process is simple and controllable, only needs normal operation and is easy to realize industrialization, therefore, the prepared heat-conducting electronic material composition has good heat conductivity and mechanical properties, and development applications of the heat-conducting electronic material composition can be met.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, and in particular relates to a heat-conducting electronic material composition. Background technique [0002] Composite materials are important basic materials for high-tech fields such as information technology, biotechnology, and energy technology, as well as for national defense construction. At the same time, they also play a very important role in transforming traditional industries such as agriculture, chemicals, and building materials. Since the beginning of the 21st century, the global composite material market has grown rapidly, especially in Asia, especially in China. From 2003 to 2008, China's average annual growth rate was 15%, India's was 9.5%, while Europe and North America's average annual growth rate was only 4%. There are many kinds of composite materials and they are widely used. Among them, electronic composite materials are forming a large-scale high-tech industr...
