Abstract

The invention provides a heat-conducting electronic packaging composite and a preparation method thereof. The preparation method comprises the following steps: mixing nano-alumina, nano-silica, a silane coupling agent KH-551, a gamma-aminopropyltriethoxysilane and water at first, and stirring; drying after filtering; mixing with N-methyl pyrrolidone, pyridine and triphenyl phosphate for reaction; adding lithium chloride and methyl alcohol for further reaction; filtering, flushing with N-dimethyl formamide and drying; re-adding acetone for ultrasonic dispersion; mixing bisphenol A epoxy resin, Neodymium(III) 2,4-pentanedionate and water, heating, and stirring for dissolution; mixing the two mixtures, and stirring while performing ultrasonic treatment; performing water bathing, adding 3,5-diaminobenzoic acid, N-aminoethylpiperazine and trimethyl hexamethylene diamine, stirring, and then conducting vacuum degassing; finally, pouring the mixture into a die for curing to obtain the heat-conducting electronic packaging composite. The heat-conducting electronic packaging composite has excellent heat stability, and meanwhile, has very good heat conductivity and a good heat dissipation effect.

Description

technical field [0001] The invention relates to the field of materials, in particular to a heat-conducting electronic packaging composite material and a preparation method thereof. Background technique [0002] With the rapid development of science and technology, the development of electronic integration and assembly technology is also very rapid, and the electronic devices and circuits are developing towards miniaturization and shrinking continuously. At the same time, its workload is getting bigger and bigger, the frequency is getting higher and higher, and the heat generated is also increasing. In order to make the electronic device work effectively for a long time, it must solve its heat dissipation problem and prevent the temperature from continuously increasing. Increase and reduce its working efficiency and service life. Traditional electronic packaging materials mainly use ceramic packaging materials, but they have disadvantages such as insufficient thermal conduct...
