Embodiment 1

[0016] Embodiment 1: In the laboratory, using phenylethyl alcohol as a marker, measure its dispersion and release in the polyethylene glycol system, and the polyethylene glycol with molecular weight of 4000-6000 is in the range of 60-80 o C heated until completely melted, cooled to 50-55 o C, add phenylethyl alcohol and polar / non-polar block polymer functional nano-dispersion aids (20% of the total amount) according to 20% by mass, stir thoroughly for 10-20min, then cool to solid state. at -10-25 o C crush into granules in frozen state, sieve, and take granules between 40-60 mesh. Add the obtained polyethylene glycol flavoring granules to cellulose acetate filter sticks at a rate of 400 mg / piece to make binary composite filter sticks, and then machine-roll them to make cigarettes. Take 1g of polyethylene glycol particles containing phenylethyl alcohol and place it in a 250mL ground-mouth Erlenmeyer flask, in a water bath of 60 o C until completely melted, add 50ml of t...

Embodiment 2

[0030] Embodiment 2: This embodiment is the same as embodiment 1, and the difference is that phenethyl alcohol and polar / nonpolar block polymer functional nanodispersion are added in the polyethylene glycol that melts completely As an auxiliary agent, add polyethylene glycol particles containing phenylethyl alcohol to the cellulose acetate filter stick at a rate of 40 mg / piece, and the rest of the steps are the same.

Embodiment 3

[0031] Embodiment 3: This embodiment is the same as embodiment 1, the difference is that in the completely melted polyethylene glycol, add phenylethyl alcohol and polar / non-polar block polymer functional nano-dispersion by 10% by mass Auxiliary, add 100mg / piece of polyethylene glycol liquid containing phenylethanol to the cellulose acetate filter stick, specifically: form a thin stream through the pores, flow into the cellulose acetate filter stick, and after the filter stick solidifies, it can form A thread-like polyethylene glycol scented thread, made into a scented slow-release filter stick.

Abstract

The invention discloses a preparation method of a perfuming filter stick with a perfumed substance released slowly. The preparation method comprises the following steps: A, heating polyethylene glycol with the molecular weight of 4000-6000 at 60-80 DEG C till polyethylene glycol is melted completely, and cooling to 50-54 DEG C, B adding 5-10% by mass of perfumed substance and polar / nonpolar block polymer into polyethylene glycol, sufficiently stirring for 10-20min and cooling to a solid, C, smashing the solid obtained in Step B in a freezing state at -10-20 DEG C into particles, sieving the particles, adding the particles between 40 meshes and 60 meshes into a cellulose acetate fiber filter stick according to the proportion of 40-400mg / cigarette to prepare a binary composite filter stick, and then rolling into a cigarette on a machine. The preparation method is significant in perfuming effect, long in perfume retention period, stable in release amount and simple in processing technique; since polyethylene glycol is a medical material, the preparation method is high in safety, convenient to use, low in environmental pollution and wide in application range, and has low requirements on the perfumed substance.

Description

Technical field: [0001] The invention relates to a preparation method of a fragranced filter stick for sustained release of fragrance substances. Background technique: [0002] With the sharp reduction of tar content in cigarettes, flavoring and re-flavoring cigarettes has gradually become a method of flavoring cigarettes. At present, there are two main methods of flavoring cigarettes, one is directly adding flavor to shredded tobacco, and the other is Class is flavored through cigarette accessories. Among them, direct flavoring of shredded tobacco is the mainstream method, with mature technology and simple processing, but the disadvantages are also obvious. The added flavor substances must directly participate in the combustion, which wastes raw materials, and will cause serious volatilization of low-boiling flavor substances. All kinds of substances are also uncontrollable. Flavoring through cigarette auxiliary materials can well make up for some shortcomings of directly...
