High-strength porous ceramic for electronic cigarette and preparation method of high-strength porous ceramic
The invention discloses a high-strength porous ceramic for electronic cigarettes and a preparation method thereof.The preparation method comprises the specific steps that 20-40 parts by weight of aluminum oxide, 30-50 parts by weight of quartz powder, 8-12 parts by weight of glass powder and 5-20 parts by weight of a pore forming agent are subjected to ball milling, and mixed powder is obtained; mixing the mixed powder with 5-20 parts by weight of paraffin, 5-20 parts by weight of polypropylene and 5-20 parts by weight of polyethylene, crushing, performing injection molding, performing heat preservation at 200 DEG C for 1-3h, performing heat preservation at 300 DEG C for 1-3h, performing heat preservation at 400 DEG C for 1-3h, performing heat preservation at 500 DEG C for 1-3h and performing heat preservation at 600 DEG C for 1-3h at a heating rate of 0.5-5 DEG C/min for discharging rubber, then heating to 1000-1300 DEG C at a heating rate of 5-10 DEG C/min, performing heat preservation for 0.5-3h, and performing sintering, so as to obtain the composite material. The high-strength porous ceramic for the electronic cigarette is obtained. The porous ceramic prepared by the method is uniform and stable in pore size distribution, has the characteristics of high porosity, high strength, controllable pore size distribution and the like, and can fully adsorb tobacco tar for atomization, improve the tobacco tar atomization effect and improve the taste.
