Problems solved by technology

Application number CN201910618056.6 uses coaxial drop molding method, using photocurable resin and paraffin as wall materials to prepare water explosion beads, but when the droplets fall on the surface of the protective liquid, they will be impacted by the liquid surface and deformed. As a result, it is difficult to control the sphericity of the blasting beads, and the falling speed of the droplets cannot be controlled. It is difficult to guarantee the light curing time, which may easily cause the problem of incomplete curing.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and in particular relates to a water popping pearl with high water retention performance and a preparation method and application thereof. Background technique [0002] Cigarette popping beads use natural polymer materials or synthetic polymer materials as wall materials, and wrap various tobacco flavors in a solid, liquid or gas form in a tiny airtight spherical capsule, which is implanted in the filter production process One or more flavor capsules that are easy to pinch and break, realize the artificially controllable characteristic flavor release during cigarette smoking, reduce the influence of the external environment on the flavor and the loss of flavor, so as to increase the humidity of the smoke and improve the quality of the filter rod. The role of the aroma interception effect. At the same time, the aroma components in the capsule are volatilized, which can realize the function of ...
