Abstract

The invention relates to a metal-film porous ceramic heating element and application thereof, more particularly to a metal-film porous ceramic heating element and application thereof in an electronic cigarette atomizer. A preparation method of a metal-film porous ceramic heating element comprises: electrothermal alloy powder and glass powder are mixed uniformly to obtain a metal powder mixture; terpineol, ethyecellulose, dibutyl phthalate, polyvinyl butyral and oleic acid are mixed uniformly to obtain an organic carrier; the metal powder mixture and the organic carrier are mixed uniformly to obtain a metal paste; and the metal paste is coated on a porous ceramic substrate by screen printing, and sintering is carried out to obtain a metal-film porous ceramic heating element. The process is simple and is easy to control; and large-scale industrial application can be realized conveniently. And the prepared metal-film porous ceramic heating element is especially suitable for an electronic cigarette atomizer.

Description

technical field [0001] The invention relates to a metal-film porous ceramic heating element and its application, in particular to a metal-film porous ceramic heating element and its application in an electronic atomizer. Background technique [0002] Metal-ceramic heating material (MCH) is an important class of heating material, because it has corrosion resistance, high temperature resistance, long life, high efficiency and energy saving, uniform temperature, good thermal conductivity, fast thermal compensation speed, and no harmful Material and other advantages, are widely used in various types of heating equipment and electrical appliances. The preparation method of the metal-ceramic heating material is generally: printing the heating layer of the metal (tungsten paste is often used now) on the ceramic base layer, and then co-sintering the ceramic heating element above 1600°C. For example: the Chinese patent "A Manufacturing Method for a New Type of Heating Element" (appl...
