Sheet alumina porous ceramic for anti-ultraviolet LED lamp heat dissipation and preparation method thereof
The invention relates to a sheet alumina porous ceramic for anti-ultraviolet LED lamp heat dissipation. The sheet alumina porous ceramic is prepared from the following raw materials in parts by weight: 34-36 parts of alpha-Al2O3, 100-105 parts of deionized water, 0.2-0.3 part of sodium polyacrylate, 2-2.3 parts of methylcellulose, 1.6-1.8 parts of glycerol, 0.2-0.3 part of K2O, 0.9-1.1 part of zirconia aluminosilicate, 0.4-0.6 part of P2O5, 1.3-1.5 part of nano-zinc oxide, 4-5 parts of nano-aluminium hydroxide, 1.2-1.5 parts of nano-copper and 0.9-1.1 parts of PVA adhesive. Porous channels among sheet alumina porous ceramic layers are communicated, the transition is good, and the thermal fatigue performance is good; and the abrasive resistance of the ceramic is improved by using the zirconia aluminosilicate, P2O5 and nano-zinc oxide, so that the ceramic has good anti-ultraviolet performance, the ceramic is beneficial for the health of people, and the service life of the chip is prolonged.
