Description
Technical field
The present invention relates to electronic cigarette micropore ceramics atomization core technical field, specially a kind of combined high-temperature micropore is high-power
Ceramic atomization core and preparation method thereof.
Background technique
At present there are many atomization core is planted, atomization core is most widely used in electronic cigarette industry.The atomization core of electronic cigarette industry
Main construction by: Oil Guide carrier, heater and metal shell form；Oil Guide carrier is mainly porous body, has capillary knot
Then structure and Oil Guide channel, tobacco tar heat through heater by the micro channel of capillary structure and generate aerosol；Heater is metal
Alloy resistance wire or mesh sheet.Present atomization core do Oil Guide carrier have ceramics, also have cellucotton, now using most
Be that cellucotton does Oil Guide carrier, cellucotton is suitable for, and tobacco tar atomization temperature in electronic cigarette industry used below at 180 DEG C
It is 170-250 DEG C, best atomization temperature is 190 DEG C；The electronic cigarette of especially big smog, its proper atomisation temperature need to reach
190 DEG C or more；By using temperature to be limited, the atomization core of Oil Guide carrier is made of cellucotton, in addition to being used temperature limiting, also
Be unable to dry combustion method, if temperature, which is higher than, or dry combustion method occurs by 180 DEG C, cellucotton just will appear peculiar smell or burn out atomization core, be higher than 190 DEG C or
Dry combustion method can also be such that cellucotton decomposes, and it is harmful substance to human body that decomposition product, which has much, endanger user's body health, very not ring
It protects.
The atomization core for making Oil Guide carrier of ceramics at present is with after silicate starting materials and the mixing of pore creating material and organic binder
It is packed into shaping mould as mixing Material, then by heater, is shaped to blank together with mixing Material, then will contain fever again
The blank of body is sintered into ceramic atomization core in 700 DEG C of following temperature；The ceramics being normally made into silicate starting materials, it need to be
1100 DEG C or more of temperature could be burned, but the production of ceramic atomization core at present, be in 700 DEG C of easy fireds below,
The reason is that heater is in the ceramic blank, cofiring together；The heater used by present various atomization cores more than 700 DEG C with
On will generate oxidation, the resistance value of heater also varies widely, thus can only in 700 DEG C of easy fireds below, and
Pore creating material and organic binder inside ceramic body cannot be completely burned off in 700 DEG C of low temperature below, and 700 DEG C with
Ceramic member intensity after lower firing is not well, to cause the existing ceramic atomization core pore-creating because burning incompletely when in use
Agent and organic adhesive object, there is peculiar smell, also because 700 DEG C are not arrived ceramic optimum burning temperature-forming also, until make ceramics not completely at porcelain,
Intensity is caused not enough to fall ceramic powders；And big smog, powerful electronic smoking set can not use this kind of easy fired
Ceramic atomization core.
