Ferrocene-modified flake alumina porous ceramic used for LED lamp heat dissipation, and preparation method thereof
The invention discloses a ferrocene-modified flake alumina porous ceramic used for LED lamp heat dissipation. The ferrocene-modified flake alumina porous ceramic is prepared from following raw materials, by weight, 34 to 36 parts of alpha-Al2O3 (particle size ranging from 2 to 8m), 100 to 105 parts of deionized water, 0.2 to 0.3 part of sodium polyacrylate, 2 to 2.3 parts of methylcellulose, 1.6 to 1.8 parts of glycerin, 1.7 to 1.9 parts of copper-plated flake graphite, 0.7 to 0.9 part of nanometer cobalt powder, 0.6 to 0.8 part of ferrocene, 0.6 to 0.8 part of zirconium oxychloride, 4 to 5 parts of nano-aluminium hydroxide, 1.2 to 1.5 parts of nano-copper, and 0.9 to 1.1 parts of PVA binder. Interlayer channels of the ferrocene-modified flake alumina porous ceramic are communicated; transition performance and thermal fatigue resistance are excellent; the ferrocene-modified flake alumina porous ceramic is provided with more metal characteristics and improved heat dispersion performance and toughness via adding of copper-plated flake graphite, nanometer cobalt powder, ferrocene, and zirconium oxychloride; compound performance of the ferrocene-modified flake alumina porous ceramic with metal is excellent, and separation or cracking is not easily caused.
