Problems solved by technology

[0005] However, the preparation process of the traditional ceramic heating element is relatively complicated, and due to the limitation of the thick film material of the conductive paste coated on the surface, the expansion of the ceramic heating element is severely limited.
[0006] Hong Qunye et al. (Hong Qunye, Li Mei, Zheng Lu, et al. Analysis of domestic e-cigarette patent technology [J]. Tobacco Science and Technology, 2019, 052(003): 74-85.) also believed that the traditional ceramic heating material is made of nano-titanium metal The heating material film is wrapped on the outside of the ceramic base to increase the heating area and improve the heating efficiency; or use double-sided ceramic materials as the heating material, and there are problems such as mixing the heating material as the heating element and causing the smell of e-liquid, carbonization, and pyrolysis. and high power consumption

Embodiment 1

[0039] Weigh 6.3 g of TiBCN powder, 0.6 g of flocculent solid polyvinyl alcohol, and 1.5 g of bio-glass powder, add them to the ball mill according to the ratio of balls to material 10:1, and take them out after ball milling and mixing for 5 hours, and add NH 4 HCO 3 The crystal grains were 6 g, and the mixed powder was obtained by mechanical stirring for 30 min.

[0040] After the mold was lubricated with graphite lubricant, 10 g of the above mixed powder was added to the mold and placed on a hydraulic press to press and form to obtain a molded sample of 25.5 mm × 14.5 mm × 10 mm.

[0041] Put the pressed molded sample into the muffle furnace, heat it to 250°C at a heating rate of 5°C / min, and keep it for 1.5 hours, then quickly heat it up to 1300°C at a heating rate of 100°C / min, and then use The temperature was raised to 1500°C at a heating rate of 20°C / min, and after holding for 2.5 hours, the temperature was naturally cooled and cooled to room temperature to obtain a hig...

Embodiment 2～4

[0050] Various raw materials were prepared according to the dosages in Table 1, and porous conductive ceramic materials for heating electronic cigarettes were prepared according to the method of Example 1. According to the test method in Example 1, the porous conductive ceramic materials prepared in each example were tested, and the specific test results are listed in Table 2.

[0053] Relevant information reports that the hardness of the heating wire material for traditional electronic cigarettes is 190-275HV, and the resistivity is 1.1×10 -6 ~1.5×10 -6 Ω / m. It can be seen from Table 2 that the hardness and resistivity of the porous conductive ceramic material of the present invention are obviously better than those of the traditional heating wire. Moreover, the resistivity of the material prepared by the present invention is one order of magnitude lower than that of the traditional material, which also shows that the heating rate of the porous condu...

Abstract

The invention relates to a porous conductive ceramic material for heating an electronic cigarette set. 4 HCO 3 Crystal grains are used as raw materials, mixed to obtain mixed powder, pressed and formed, and then sintered at a high temperature of 1500 ° C to obtain a porous conductive ceramic material. Using the porous conductive ceramic material prepared by the present invention as the heating material for electronic smoking sets overcomes the conductive form of the traditional electronic smoking set heating material outsourcing the electronic paste, and prepares a high heating rate, controllable porosity, and relatively high corrosion resistance. High-quality, high hardness and compressive strength porous conductive ceramic material for electronic cigarette heating.

Description

technical field [0001] The invention belongs to the technical field of conductive ceramic materials, and relates to a conductive ceramic material with a porous structure, in particular to a conductive ceramic material for heating electronic cigarettes and a preparation method thereof. Background technique [0002] Electronic cigarettes are electronic products that imitate cigarettes. They have the same fogging effect, various flavors and smoking sensations as cigarettes. Even the appearance of electronic cigarettes can imitate the shape of cigarettes. Electronic cigarettes use atomizers to turn pods into vapors for users to smoke. [0003] The heating elements used on the atomizer mainly include metal heating elements and ceramic heating elements. Metal heating elements are further divided into metal heating sheets or heating wires, and the materials include iron-chromium-aluminum, stainless steel, nickel-chromium alloy, pure nickel, pure titanium, etc. It is the simplest a...
