Cigarette capsule for packaging water and preparation method thereof

Abstract

The invention relates to a cigarette capsule for packaging water. The cigarette capsule is formed by hydrogel beads and a hydrophobic packaging layer covering the outer side of the hydrogel beads, thehydrophobic packaging layer is a composition of a long-chain lipid material and a reinforcing material, and a melting point is 50-110 DEG C, wherein the reinforcing material is one or more of compounds selected from the following groups: polycaprolactone, ethylene and an acrylic copolymer. Compared with a current cigarette capsule, the beneficial effect of the cigarette capsule is as follows: (1)the provided cigarette capsule for packaging the water can be suitable for extensive water-soluble and alcohol-soluble essence and flavor, and cigarette explosion beads are endowed with other functions, such as improving moisture feeling, reducing dry and stimulated feeling, and reducing a release amount of smoke harmful ingredients; (2) hydrogel is introduced to a cigarette capsule structure, sothe cigarette capsule for packaging the water provided by the invention has the strong maintaining ability to the water, and is capable of improving the water retaining capacity; and (3) polycaprolactone, ethylene, the acrylic copolymer and the like in the hydrophobic packaging layer are capable of improving the strength of waxiness, and improving the machinability resistance of the explosion beads.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and in particular relates to a water-wrapped cigarette capsule and a preparation method thereof. Background technique [0002] In recent years, cigarettes containing tobacco capsules (also known as tobacco popping beads) have become increasingly popular in the cigarette market. Tobacco capsules are added to cigarette filters as a new material for cigarettes. Consumers can crush the capsules when smoking. In this way, the essence with special fragrance is released, so as to enrich the smoke aroma, strengthen the style, and establish interactivity. [0003] In the prior art, cigarette capsules usually use oil-soluble essence and lipid solvent as essence diluent as inner core materials, and animal and vegetable gums such as gelatin, acacia gum, and alginic acid as outer wall materials. During preparation, the aqueous solutions of the inner core material and the outer wall material of the lipid a...

AI Technical Summary

Problems solved by technology

However, there are still some problems in this kind of cigarette capsules: (1) The lipid solvent itself has a certain inherent smell, and there are certain problems in coordinating with the smoke and aroma, which may cover up the fragrance of the added essence to a certain extent

(2) A large part of the existing tobacco flavors and fragrances are water-soluble substances and cannot be dissolved in lipid solvents. Therefore, the types and scope of flavors that can be applied to such tobacco capsules are greatly reduced, and the types of flavors that can be selected and applied are extremely limited , which is not conducive to the promotion and application of tobacco capsules in cigarette brands

(3) The lipid solvent in these cigarette capsules overflows after the capsule is crushed, which easily contaminates the tow of the cigarette filter rod, and even penetrates through the filter rod forming paper and tipping paper, affecting the appearance quality of the cigarette

(4) The functions of these cigarette capsules are relatively single, usually only as a means of flavoring, and the harm reduction function often cannot be integrated in such cigarette capsules

Although the above technology can complete the wrapping, the process is relatively complicated, and the wax strength of the outer layer is not enough, the yield is not high and it is easy to break, so it cannot adapt to industrial production

Patent CN201610513655 uses polymerizable bisphenol A epoxy acrylic resin and other resins as the wall material, and uses the photopolymer of the wall material to form a dense film layer through the coaxial double-nozzle nozzle drop method to prepare water capsules. However, due to the need to use a large amount of The photoinitiator and possible monomer residues have a certain impact on the safety of the water capsule. At the same time, the wall material formed by photopolymerization is usually brittle, which is not conducive to subsequent processing and molding.
