Abstract

The invention discloses nano porous ceramic for an atomizing core and a preparation method. The ceramic is prepared from 1 to 60 parts of nano silicon oxide, 10 to 80 parts of ceramic powder, 1 to 50parts of a pore-forming agent and 1 to 40 parts of a sintering aid. The preparation method comprises the steps of (1) weighing raw materials including nano silicon dioxide, ceramic powder, a pore forming agent and a sintering aid, and putting the raw materials into a ball milling device for mixing and ball milling; (2) baking and drying the ball-milled mixture to obtain mixed powder; (3) heating paraffin to a molten state, adding the mixed powder while stirring, and continuously stirring for 1-8 hours after the addition is finished so as to obtain paraffin slurry; (4) injecting the paraffin slurry into a pre-prepared mold, cooling and molding, and demolding to obtain a wax mold; (5) preheating the wax mold to remove wax to obtain a dewaxed sample; and (6) sintering the dewaxed sample, andcooling to obtain the nano-porous ceramic. The preparation method has the beneficial effects that the problem that the requirements of high porosity and high strength cannot be met simultaneously in the prior art is solved, and the problem that impurities and heavy metals are easy to separate out is solved.

Description

technical field [0001] The invention belongs to the technical field of atomizing cores, in particular to nanoporous ceramics for atomizing cores and a preparation method thereof. Background technique [0002] The atomizing core is mainly used in electronic atomizers to heat and atomize the liquid to be atomized into aerosol, steam, or mist for users to inhale. The liquid to be atomized can be smoke liquid or a solution containing medicine for health care purposes. [0003] At present, the atomizing core includes porous ceramics as the base material as the heating element, and the porous ceramic heating element mainly adopts the sintering process of the porous ceramic matrix, and is sintered at a relatively low temperature. The existing porous ceramic atomizing core and its preparation method use conventional ceramic powders to be ground and mixed as ceramic powder materials, and the method to reduce the sintering temperature is to add glass powder or quartz sand, which has ...
