A kind of porous heating film and preparation method thereof

Abstract

The invention discloses a porous heating film and a preparation method thereof. The porous heating film sequentially comprises a base-like layer, a heating layer and a stable catalysis layer, wherein the base-like layer is prepared from at least one of TiN, ZrN and TiC; the heating layer is made of a metal material; and the stable catalysis layer is made of a noble metal material. Compared with a silky heating body, the porous heating film has the advantages that a contact area of the porous heating film and smoke liquid is larger, the heating efficiency is high, and more energy is saved; and after the stable catalysis layer made of the noble metal material is added, for a general thin film material, two effects are achieved: firstly, the stability of a thin film is improved, so that the service life of a sample is prolonged; and secondly, the atomization amount of the sample is increased and a brand-new mode of "low power and great smog" is realized. The materials used by the porous heating film are human body-friendly materials, which are healthier. The preparation process is simple and easy for mass production.

Description

technical field [0001] The invention relates to a heating film and a preparation method thereof, in particular to a porous heating film applied to an electronic atomizer. Background technique [0002] Energy saving, safety, and environmental protection are a theme in today's society, so people are required to reflect this theme as much as possible in practical considerations, application production, etc. As a substitute for cigarettes, electronic cigarettes have been recognized by many countries for their energy-saving, safety, and environmental protection compared with traditional cigarettes. [0003] The main structure of electronic cigarettes includes three parts: lithium batteries, electronic atomizers, and cartridges. As the core component of electronic cigarettes, electronic atomizers have become the key research and development targets of many companies. The first-generation and second-generation electronic cigarette atomizers currently on the market use metal hair ...

AI Technical Summary

Problems solved by technology

Their disadvantages are: 1. It is easy to produce burnt smell; 2. The metal wire is fatigued and easy to break when it is energized; , the amount of atomization can only be increased if the atomization amount is increased, but if so, its life will be greatly reduced; 5. Resistance drift; 6. Short life

[0004] At present, the heating wires used in electronic cigarettes on the market are generally nickel-chromium heating wires. Nickel and chromium have been proved to be harmful to the human body, and there are potential safety hazards in the process of using electronic cigarettes.

In short, traditional heating methods and heating materials are difficult to meet the theme of energy saving, safety and environmental protection in today's era
