Preparation method of ceramic cooling composite material
The invention belongs to the technical field of cooling high-power LED (Light Emitting Diode) lamps, and particularly relates to a preparation method of a ceramic cooling composite material. The preparation method comprises the steps of (1) preparing composite sintering aids; (2) preparing ceramic slurry; (3) forming ceramics. The preparation method has the following beneficial effects that (1) the heat conductivity coefficient of the ceramic cooling composite material is large, the heat resistance is excellent, the bending strength is high, and the phenomena of bending, warping and the like do not occur; (2) a proper sintering method and proper sintering aids are adopted, so that the densification of a ceramic sintering body is realized, and the heat conductivity of ceramic materials is greatly increased; (3) melamine in a formula of the preparation method can generate aluminum nitride and carbon nitride at high temperature, so that the rigidity and surface gloss of the ceramic materials are increased.
