Diamond particle reinforced alloy melt thermal interface material and its preparation method
The invention discloses a diamond particle reinforced molten alloy thermal interface material and a preparation method thereof. The diamond reinforced molten alloy high-thermal conductivity material comprises the following raw materials in parts by mass: 40 to 100 parts of a molten alloy, 30 to 80 parts of diamond particles, 10 to 20 parts of tungsten metal and 10 to 20 parts of a diluent. The preparation method comprises the steps that diamond particles are subjected to surface treatment sequentially, the surfaces are coated with tungsten layers, the diamond particles are added into a liquidmetal, and the diamond particle reinforced molten alloy thermal interface material is obtained. Through adoption of the technical scheme, on one hand, interface bonding strength of the diamond particle reinforced molten alloy thermal interface material is improved, and on the other hand, the diamond particles are better dispersed in the liquid metal, the heat-conducting property is improved, operation is simple, the thermal conductivity is high, thermal stability is high, and the material can be utilized in the fields of heat dissipation of electric appliances and electronic packaging materials, and the like.
