Problems solved by technology

Now other similar atomizing core nickel paste products mainly use nickel-chromium alloy powder as the main conductive material. This nickel-chromium alloy powder contains chromium, and it is easy to produce peculiar smell with a lot of e-liquid under high temperature heating state, resulting in poor taste, and electronic smoke The metal sintering temperature of the chemical core is relatively high, which requires high sintering process for large-scale industrial production
The width of the circuit line diameter after printing and sintering of this kind of paste is basically 0.3-0.5 mm, and the thixotropy is poor during the printing process, and the height is only 80-100 microns, and it is prone to problems such as virtual printing and disconnection. Small volume of suction mist

Abstract

The invention discloses a nickel slurry for an electronic atomization core and a preparation method thereof. The slurry is suitable for various porous ceramic atomization cores, especially for porous silicon oxide ceramics. The slurry composition and its mass percentage are: 60-80% of nickel powder, 1-10% of titanium hydride powder, 3-16% of glass powder, and 8-30% of organic vehicle. Compared with the current atomization core nickel paste technology, the electronic atomization core nickel paste provided by the present invention has relatively ideal thixotropy, and can continuously print thin lines with very good aspect ratios without virtual printing and broken lines, etc. problem, and has a lower metallization sintering temperature, and the composition does not contain toxic metals such as lead and chromium. It has low requirements for large-scale industrial production and sintering process. , It has a high degree of reduction to the flavor of e-liquid, no peculiar smell and good taste during the atomization process.

Description

technical field [0001] The present invention relates to the technical field of electronic cigarette cores, in particular, to a nickel slurry for electronic cigarette cores and a preparation method thereof. Background technique [0002] With the development of the electronic cigarette industry, the design of various electronic cigarette components is also approaching maturity. Among them, the technology of the electronic cigarette fogging sheet of the metallized porous ceramic atomizing core has also become more and more with the development requirements of the industry. more and more refined. For the heating situation of the matching atomizing core and the e-liquid, the degree of reduction of the flavor matching the atomizing core and the e-liquid is also getting higher and higher. Metal circuits with good line aspect ratio and good continuity have become one of the new technological development requirements. At present, other similar atomizing core nickel slurry products ...
