Embodiment 1

[0081] 12 g of polyvinyl alcohol was weighed and dissolved in 400 mL of deionized water at 80° C. to obtain a polyvinyl alcohol solution.

[0082] 3 g of polylactic acid particles were weighed and dissolved in 30 mL of dichloromethane to obtain a polylactic acid solution.

[0083] The polylactic acid solution and propylene glycol were put into syringes, placed on two syringe pumps, and connected to a coaxial double-needle reactor. The flow rates of the two syringe pumps were 5mL / h (the flow of propylene glycol) and 6mL / h (poly The flow rate of lactic acid solution) was dropped into the polyvinyl alcohol solution, mechanically stirred for 6h, the stirring speed was 250r / min, the product was vacuum filtered, washed with deionized water, and then collected to obtain polylactic acid functional capsules. The particle size of the capsules was measured to be 3.3 mm.

Embodiment 2

[0085] 12 g of polyvinyl alcohol was weighed and dissolved in 400 mL of deionized water at 80° C. to obtain a polyvinyl alcohol solution.

[0086] 3.6 g of polylactic acid particles were weighed and dissolved in 30 mL of dichloromethane to obtain a polylactic acid solution.

[0087] The polylactic acid solution and deionized water were put into the syringes, placed on two syringe pumps, and connected to the coaxial double-needle reactor. The flow rates of the two syringe pumps were 5mL / h (water flow) and 6mL / h respectively. h (flow rate of polylactic acid solution), drop into polyvinyl alcohol solution, stir mechanically for 6h, stirring speed is 250r / min, filter the product under reduced pressure, wash with deionized water, and then collect to obtain water-in-polylactic acid capsules . The measured particle size of the water-filled capsule is 3.5 mm (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; the details are as follows:

[0090] 12 g of polyvinyl alcohol was weighed and dissolved in 400 mL of deionized water at 80° C. to obtain a polyvinyl alcohol solution.

[0091] 4.5 g of polylactic acid particles were weighed and dissolved in 30 mL of dichloromethane to obtain a polylactic acid solution.

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

Abstract

The invention relates to a heated non-burning cigarette. The heated non-burning cigarette comprises a tobacco substance section and a filter which are sequentially connected, and the tobacco substancesection is filled with a functional capsule; a core material of the functional capsule is a solution containing tobacco tar; and a wall material is polylactic acid. The invention further provides a preparation method of the heated non-burning cigarette. The preparation method comprises the steps: the solution containing the tobacco tar serves as a core material solution; an organic solvent dissolved with the polylactic acid serves as a wall material solution; the core material solution and the wall material solution are dropwise added into a solidified solution together through an inner holeof an electrostatic spinning coaxial syringe needle (can also be named as the coaxial syringe needle), and a gap between the inner hole and an outer hole of the electrostatic spinning coaxial syringeneedle correspondingly, after stirring, solid and liquid separation, washing and drying are conducted, and the functional capsule is obtained; and then an existing method is adopted, and the non-burning cigarette is assembled. The tobacco tar component is added in a clad mode, and thus stability of the smoke atomization quantity and the smoke component is guaranteed.

Description

technical field [0001] The invention relates to the field of the tobacco industry, in particular to a coated cigarette additive material. Background technique [0002] Low-temperature heating non-combustion cigarettes are one of the important categories of new tobacco products. Generally, the satisfaction and part of the tobacco flavor are delivered to consumers by heating non-burning tobacco substances. Their appearance and consumption methods are also similar to traditional cigarettes. To a certain extent, it adapts and meets the physical and psychological needs of consumers. This "heat-not-burn" method allows tobacco to be heated only at a lower temperature (ideal temperature range of 250-300°C), which avoids the formation of tar and a large number of harmful compounds caused by the high-temperature environment during tobacco combustion. There is no sidestream smoke, no second-hand smoke will be generated, and no impact on the public environment will be produced, which a...
