Embodiment 1

[0081] Weigh 12g of polyvinyl alcohol and dissolve it in 400mL of deionized water at 80°C to obtain a polyvinyl alcohol solution.

[0082] Weigh 3g of polylactic acid particles and dissolve in 30mL of dichloromethane to obtain a polylactic acid solution.

[0083] The polylactic acid solution and propylene glycol were put into syringes respectively, placed on two syringe pumps, connected to the coaxial double-needle reactor, and the flow rates of the two syringe pumps were 5mL / h (the flow rate of propylene glycol), 6mL / h (poly Lactic acid solution), drop into polyvinyl alcohol solution, mechanically stir for 6h, stirring speed is 250r / min, filter the product under reduced pressure, wash with deionized water, and then collect to obtain polylactic acid functional capsules. The particle size of the capsules was measured to be 3.3 mm.

Embodiment 2

[0085] Weigh 12g of polyvinyl alcohol and dissolve it in 400mL of deionized water at 80°C to obtain a polyvinyl alcohol solution.

[0086] Weigh 3.6g of polylactic acid particles and dissolve in 30mL of dichloromethane to obtain a polylactic acid solution.

[0087] Put the polylactic acid solution and deionized water into syringes respectively, place them on two syringe pumps, connect the coaxial double-needle reactor, and the flow rates of the two syringe pumps are 5mL / h (water flow rate) and 6mL / h respectively. h (the flow rate of the polylactic acid solution), drip into the polyvinyl alcohol solution, mechanically stir for 6h, and the stirring speed is 250r / min, the product is vacuum filtered, washed with deionized water, and then collected to obtain polylactic acid-in-water capsules . The particle diameter that measures water-packed capsule is 3.5mm (see image 3 -a).

Embodiment 3

[0089] Compared with Example 2, the main difference is that the PLA solubility of the wall material solution is 0.15g / mL; details are as follows:

[0090] Weigh 12g of polyvinyl alcohol and dissolve it in 400mL of deionized water at 80°C to obtain a polyvinyl alcohol solution.

[0091] Weigh 4.5g of polylactic acid particles and dissolve in 30mL of dichloromethane to obtain a polylactic acid solution.

[0092] Put the polylactic acid solution and deionized water into syringes respectively, place them on two syringe pumps, connect the coaxial double-needle reactor, and the flow rates of the two syringe pumps are 5mL / h (water flow rate) and 6mL / h respectively. (the flow rate of the polylactic acid solution); drip into the polyvinyl alcohol solution, mechanically stir for 6 hours, the stirring speed is 250r / min, the product is filtered under reduced pressure, washed with deionized water, and then collected to obtain polylactic acid water-in-capsules. The particle size of the wat...

Abstract

The invention relates to a heat-not-burn cigarette, which comprises sequentially connected tobacco substance segments and filter tips, the tobacco substance segments are filled with functional capsules; the core material of the functional capsules is a solution containing smoke oil; the The wall material is polylactic acid. The present invention also provides the preparation method of the heat-not-burn cigarette, using the solution containing e-liquid as the core material solution; the organic solvent dissolved with polylactic acid as the wall material solution; and the core material solution through the electrospinning coaxial needle (The present invention can also be referred to as the coaxial needle) The inner hole and the wall material solution are added dropwise to the coagulation liquid through the gap between the inner and outer holes of the electrospinning coaxial needle, and after stirring, the solid-liquid separation, washing, The functional capsules are obtained after drying, and then the existing method is used to assemble the non-combustible cigarettes. In the present invention, the smoke oil component is added in the form of coating, so as to ensure the stability of smoke atomization amount and smoke components.

Description

technical field [0001] The invention relates to the field of tobacco industry, in particular to a wrapping cigarette additive material. Background technique [0002] Low-temperature heating-not-burning cigarettes are one of the important categories of new tobacco products. Generally, satisfaction and part of the tobacco aroma are delivered to consumers through heating-not-burning tobacco substances. Their appearance and consumption methods are also similar to traditional cigarettes. To a certain extent, it adapts and satisfies the physiological and psychological needs of consumers. This "heat not burn" method enables the tobacco to be heated only at a lower temperature (ideal temperature range 250-300°C), avoiding the generation of tar and a large number of harmful compounds caused by the high temperature environment when the tobacco is burned, and because the basic There is no sidestream smoke, no second-hand smoke, and no impact on the public environment, which alleviates...
