Abstract

The invention discloses a composition as well as an anti-leakage oil layer and an atomizing core thereof. The composition comprises the following components: ceramic powder, a sintering aid, a pore forming agent, a plasticizer, a dispersing agent and a solvent. After the composition is prepared into slurry, at least part of the surface of the atomizing core is coated with the slurry to form a leakage-proof oil layer with low porosity and small pore diameter, and the oil leakage-proof capacity of the atomizing core is remarkably improved while the atomizing effect is not reduced.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to a composition, an oil leakage prevention layer and an atomizing core. Background technique [0002] At present, the commonly used tripod-shaped ceramics are generally equipped with embedded heating wires, which generate heat after being energized, or a layer of circuit is printed on the bottom, which heats up and generates heat after energizing to atomize the e-liquid. Due to the porous structure of the atomizing core, oil leakage will inevitably occur during transportation or use. The main reason is that in order to ensure that the oil guide of the atomizing core can keep up with the atomization speed of the e-liquid, the porosity of the atomizing core is required to be relatively high, about 50%, and the pore diameter is generally above 20 μm. As a result, the oil-locking ability of ceramics will be greatly reduced. During transportation, or when the user is using it, if it ...
