Preparation method of liquid metal heat-conducting paste mixed with high-heat-conductivity particles

The invention discloses a preparation method of liquid metal heat-conducting paste mixed with high-heat-conductivity particles, and particularly relates to the liquid metal heat-conducting paste mixed with the particles, which is prepared by replacing silver powder with silver coated copper powder and adding the high-heat-conductivity particles such as copper powder into liquid metal. Meanwhile, the invention further provides a treatment method of the silver-coated copper powder, namely, the silver-coated copper powder is subjected to surface treatment through a halogen-containing silane coupling agent, the stability of the composite material can be improved through the preparation method, and the performance of the liquid metal heat-conducting paste is improved by increasing the heat conductivity of a base material (liquid metal). Compared with the traditional liquid metal heat-conducting paste, the heat conductivity and the stability are improved. 本发明公开了一种混有高热导率颗粒的液态金属导热膏的制备方法，特别是涉及到将银包铜粉代替银粉、铜粉等高热导率颗粒添加到液态
