Problems solved by technology

However, the pore size distribution of porous ceramic products currently on the market is not uniform, and porous ceramics with uniform pore size and porosity are usually used. When the types of e-liquid are different, the pore size and porosity of the porous ceramics do not match the viscosity of the e-liquid. The atomization effect of the e-liquid is poor, and the taste is poor, which cannot meet the smoking frequency and taste of consumers

preparation example Construction

[0040] The embodiment of the present invention also discloses a preparation method of porous ceramics for electronic cigarettes, please refer to figure 1 , figure 1 It is a schematic flowchart of a method for preparing porous ceramics for electronic cigarettes according to an embodiment of the present invention, and the method includes:

[0041] Step S1: Weigh the ceramic powder, sintering aid, and pore-forming agent according to the formula, place them in a mixing device and mix for at least 5 hours to obtain a mixed powder.

[0042] In step S1, the mixing device includes one of a roller mill, a V-type mixer and a planetary ball mill. Preferably, in this embodiment, the mixing device is a V-type mixer. By mixing the ceramic powder with the sintering aid and pore-forming agent, it is beneficial to increase the contact area between the ceramic powder, the sintering aid and the pore-forming agent, thereby improving the subsequent mixing efficiency and mixing effect.

[0043] S...

Embodiment 1

[0053] Weigh 30% diatomite, 5% glass sand, 10% polystyrene microspheres, 22% glass powder, 28% paraffin and 5% stearic acid, glass powder The softening temperature of the polystyrene microsphere is 480-560 °C, the particle size of the polystyrene microsphere is 10 μm, and the melting point of the paraffin is 58 °C.

[0054] S1: Put the weighed diatomite, glass sand, polystyrene microspheres and glass powder in a V-type mixer and mix for 5 hours to obtain a mixed powder;

[0055] S2: Put the mixed powder, weighed paraffin wax and stearic acid in a wax blender and knead for 5 hours at a temperature of 70°C to obtain a kneaded material;

[0056] S3: placing the mixed material in a hot die casting machine for hot die casting at a temperature of 60° C. and a pressure of 0.2 MPa to obtain a molding material;

[0057] S4: Perform wax removal treatment on the molding material at a temperature from room temperature to 400°C, the temperature rise rate from room temperature to 200°C is ...

Embodiment 2

[0060] Weigh respectively 32% diatomite, 8% quartz sand, 17% polystyrene microspheres, 20% glass powder, 18% paraffin and 5% oleic acid according to mass percentage, the glass powder The softening temperature is 850-950°C, the particle size of polystyrene microspheres is 20 μm, and the melting point of paraffin is 58°C.

[0061] S1: Put the weighed diatomite, quartz sand, polystyrene microspheres and glass powder in a V-type mixer and mix for 5 hours to obtain a mixed powder;

[0062] S2: Mixing the mixed powder with the weighed paraffin wax and oleic acid in a wax mixer at a temperature of 75°C for 5 hours to obtain a mixed material;

[0063] S3: placing the mixed material in a hot die casting machine for hot die casting at a temperature of 60° C. and a pressure of 0.2 MPa to obtain a molding material;

[0064] S4: Perform wax removal treatment on the molding material at a temperature from room temperature to 400°C, the temperature rise rate from room temperature to 200°C is...

Abstract

The invention relates to the technical field of electronic cigarettes. The invention particularly relates to porous ceramic for an electronic cigarette and a preparation method thereof. The porous ceramic for the electronic cigarette is composed of the following components in percentage by mass: 30-60% of ceramic powder, 1-30% of a pore forming agent, 5-40% of a sintering aid, 10-40% of paraffin and 1-10% of a modifier. The ceramic powder comprises at least two of diatomite, cordierite, fly ash, aluminum oxide, zirconium oxide, silicon carbide, silicon nitride, quartz sand, zircon sand, glasssand, kaolin and clay. The porous ceramic prepared by the method is uniform and stable in pore size distribution; the aperture and porosity of the porous ceramic can be adjusted according to the tasteof a user and the characteristics of tobacco tar, so that the tobacco tar can be fully adsorbed and atomized, the tobacco tar atomization rate is greatly increased, the smoke amount is increased, andthe problems of poor tobacco tar atomization effect and poor taste in the current market are solved.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to a porous ceramic for electronic cigarettes and a preparation method thereof. Background technique [0002] With the development of society and the improvement of people's health awareness, consumers have put forward higher requirements for smoking safety. Because smoking is prone to dependence and addiction, it is very difficult to quit smoking in a short time. In order to meet the current market demand, electronic cigarettes have become the first choice for smokers to get rid of their addiction to cigarettes. [0003] As the heating element of the electronic cigarette, the atomizer is one of the important components. Its principle is: through the power supply of the battery to generate heat, the e-liquid stored in the atomizer is volatilized, and a certain amount of smoke is generated, so that consumers can continue to smoke while smoking. When inhaled, the effec...
