A kind of multifunctional cigarette popping ball based on liquid marbles and preparation method thereof

Technical field:

The invention relates to a multifunctional cigarette popping ball, in particular to a multifunctional microcapsule based on liquid marbles and having the characteristics of water retention, moisturizing, disinfection and the like. The multifunctional microcapsules have excellent stability, water retention, disinfection and other properties, can effectively remove harmful components in the inhaled gas of cigarettes and increase the taste of inhalation. The present invention further relates to a preparation method of the multifunctional cigarette popping beads. The invention belongs to the fields of colloid and interface science and micro-nano encapsulation.

Background technique:

It is well known that smoking is harmful to health because there are a large number of polycyclic aromatic hydrocarbons and their derivatives and nitrosamines in tobacco, which are the main carcinogens that induce lesions in smokers. According to the World Health Organization, 5.4 million people die from smoking every year in the world, and this data continues to grow rapidly every year.

Conventional commercially available cigarette filter tips are made of cellulose acetate at present, but the filter tips of these conventional cigarettes only play a partial barrier effect on toxic and carcinogenic substances in tobacco. At the same time, the smoke of conventional cigarettes is relatively dry, which can easily cause dry and itchy throats of smokers. Long-term use also makes smokers susceptible to chronic pharyngitis and other problems. Therefore, how to reduce the content of toxic substances and carcinogens in cigarette smoke is the focus of current research.

Through the patent search of the existing technology, it is found that the methods that have been successfully used to reduce the toxic substances and carcinogens in cigarette smoke mainly include cellulose acetate filter containing disinfectant (Chinese patent, patent number: 97195540.9), internal Functional filter containing microcapsules (US patent, patent number: 08/534,050; Chinese patent, patent number: 97195540.9). However, the preparation process of these existing functional filters is relatively complicated, the cost is high and the stability is poor, and it is generally impossible to realize large-scale batch production. Therefore, how to effectively reduce the toxic and carcinogens in cigarette smoke remains a challenging problem.

detailed description:

The following examples will further illustrate the present invention in conjunction with the accompanying drawings. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation methods and processes are given, but the protection scope of the present invention is not limited to the following embodiments. For the experimental methods without specific conditions indicated in the following examples, the conventional conditions or the conditions suggested by the manufacturer are usually followed.

Example 1:

On the plastic substrate scattered with hydrophobic powder, drop 10 μL of saturated potassium acetate droplet with a microsampler, and then shake the substrate to make the surface of the droplet fully cover the powder to form a liquid marble.

Make a mixture of epoxy soybean oil acrylic resin and diluent at a volume ratio of 1:5, then add 3% of the I-184 photoinitiator by mass fraction, stir and mix evenly, and spray it on the surface of the liquid marbles in a UV light curing machine and solidified for 3 minutes to obtain microcapsules.

Implementation effect of this embodiment: Fig. 1 is a schematic diagram of the preparation route of microcapsules. The hydrophobic powder is used as a stabilizer to prepare liquid marbles by a rolling drop method, and a photocurable coating containing an initiator is sprayed on the outside of the liquid marbles, and cured by ultraviolet radiation to obtain capsules.

Figure 2 is a digital photo of the prepared liquid marbles. As shown in the figure, the prepared liquid marbles have a spherical structure and can stably exist on the surface of the hydrophilic substrate.

Fig. 3 is a digital photograph of the section of the liquid marble in different time periods. It can be seen that the liquid marbles have good water retention and moisturizing properties, and can maintain a good spherical structure even after 90 minutes without collapse, which provides a reliable basis for the subsequent encapsulation process.
