The present invention relates to a functional cigarette filter that can remove the smell of the mouth that may occur during smoking by the microcapsules to the cigarette filter and gives a refreshing, in particular, thousands of micro size in the water macro containing the functional material Microcapsules were incorporated into the cellulose acetate fiber filter to manufacture tobacco filters containing functional microcapsules, preventing microcapsules from being released by the random release of functional substances and releasing functional substances only during or after smoking. It relates to a method for producing a functional tobacco filter used.

Currently, in case of smoking cigarettes, the fragrance of tobacco is used as a fragrance by spraying menthol as a fragrance and spraying it with solvent.

For example, Korean Patent Laid-Open Publication No. 2002-0082202 describes a functional cigarette filter incorporating muscon, mausoleum, or mixtures thereof, and Publication No. 95-005400 contains a scented odor adsorbent. The manufacturing method of the tobacco filter is described,

Korean Patent Publication No. 10-0193377 discloses a method for preparing a particulate composite molecular composition for a cigarette filter.

In this way, there is a problem that the functional material is exposed to the air and the deformation occurs, or the fragrance intensity is weakened over time and over time.

In addition, the Korean Registered Patent Publication No. 10-0301342 (WO1998 / 15197; 1998.4.16) as a product using a capsule in the tobacco filter is a toxic by wet filtration of tobacco smoke by containing a wetting agent such as sodium pyroglutamate in the porous substrate It is used to remove material.

However, these products have a disadvantage in that the service life of the cigarette is determined as the amount of volatilizer is increased.

In order to solve the problems of the prior art, the invention of the present application microencapsulates a functional material (fragrance, natural oil, etc.) into a polymer material or an inorganic material in the size of several microns to several thousand microns by chemical and physical methods When the user wants to impact the microcapsules, the microcapsule wall is destroyed and the active ingredient (fragrance, natural extract oil, etc.) is released to produce a functional cigarette filter incorporating microcapsules to provide a refreshing feeling during or after smoking. It is an object of the present invention to provide a method.

In order to achieve the above object, the present invention dissolves 10 parts by weight of polyvinyl alcohol (polymerization degree 1700) in 60 parts by weight of distilled water, and adds 20 parts by weight of an internal filler, which is a fragrance or natural extraction oil, to 3 minutes at 5000-10000 rpm. After stirring, adding 10 parts by weight of a reactive urea resin to increase the temperature to 60 ℃, and then maintained for 2 hours to prepare a microcapsule;

Separating the prepared microcapsules using a suction filtration apparatus and drying them at room temperature to separate the microcapsule powder; A filter of a functional tobacco filter comprising spraying the prepared microcapsules with cellulose acetate fibers together with activated carbon to form a filter or by filling activated carbon and microcapsules in an adsorbent layer of a triple filter to form a microfilter-filled tobacco filter. It relates to a manufacturing method.

In the manufacturing method, as the functional material to be filled in the microcapsules 1, one or a mixture of natural extracting oils such as fragrance and synthetic oil is used.

In addition, as a method of preparing the microcapsules (1), in-suit polymerization method (selecting oil as the core material, emulsifying it in an aqueous system in which an emulsifier is mixed, and then adding melamine-formaldehyde resin as a wall material, temperature and pH If the conditions are met, the wall material is slowly reacted and grows at the oil interface.The wall material is thermosetting resin, which is stable to heat, and can induce the release of internal materials only by pressure), interfacial polymerization method, and coacervation method ( It can be prepared using a method of forming a wall material by forming an ionic complex between polymers by adjusting a salt, a metal or a pH that a polymer solution can induce a reaction between each other, and a material capable of forming a wall material of a microcapsule. Melamine resin, urea resin, urethane resin, gelatin, starch, cellulose and high boiling point of the sole or mixture thereof The.

As a fragrance substance filled in the microcapsules (1), it is a compound selected from natural and synthetic oils such as lemon, peppermint, lavender, orange, grape, vanilla, geranium, sol, or synthetic oil. It is to use a mixture of 95 parts by weight.

On the other hand, as shown in Figure 2, when the filter is manufactured by mixing the microcapsules (1) with activated carbon, it is easy to manufacture a filter for a cigarette given the functionality, there is an advantage that can adjust the time to exhibit the functionality .

Hereinafter, the method for preparing microcapsules according to the present invention as described above has been described by using a method using melamine as an example, to prepare a functional tobacco filter using the microcapsules.

Hereinafter, the present invention will be described in detail with reference to the following Examples.

After maintaining for a period of time, the resultant was filtered by suction, dried at room temperature, and prepared by preparing microcapsules having various sizes (several to several thousand micros),

2nd process (tobacco filter manufacture)

Functional capsule containing microcapsules by inserting a certain amount of microcapsules into a portion in which activated carbon is injected between the cellulose acetate filter and the filter used to filter the toxic substances and improve the taste of cigarettes when the microcapsules are manufactured in the triple filter. A triple filter was prepared.

Example 2

The microcapsules prepared in the first step of Example 1 were spray-injected into the cellulose acetate fibers, the raw material for the tobacco filter, to prepare a dual-use tobacco filter containing microcapsules evenly in the cellulose acetate fibers.

Example 3

10 g of the microcapsules manufactured in the first step of Example 1 were mixed with 90 g of activated carbon, and a predetermined amount was mixed into the activated carbon inlet of the triple filter to prepare a triple filter for functional tobacco containing microcapsules.

Example 4

10 g of styrene-maleic anhydride (Poly (styrene-maleicanhydride)) was dissolved in 700 g of distilled water in a three-necked flask, 200 g of lemon oil was added, stirred at 10000 rpm for 3 minutes, and 190 g of melamine resin was added to raise the temperature to 60 ° C. Preparing the microcapsules by holding the mixture for 2 hours, and performing suction suction filtration to dry at room temperature to prepare microcapsules containing a functional material;

The prepared microcapsules were spray-injected into the cellulose acetate fibers which are raw materials for the tobacco filter, and microcapsules were evenly contained in the cellulose acetate fibers to prepare functional tobacco filters.

As described above, the present invention is produced when smoking microcapsules containing a functional substance (fragrance, extracting oil, etc.) in the filter portion for filtering toxic substances inhaled, such as smoke during smoking, in the size of several micro to several thousand microns. It can induce an effect that can filter out toxic substances or reduce the smell and rejection of the mouth.
