Description

Smoking agent, smoking material and preparation method thereof

Technical Field

The invention relates to the technical field of tobacco materials, in particular to a smoke agent, a smoke material and a preparation method thereof.

Background

With the development of electronic cigarettes and heating non-combustible tobacco products, various novel tobacco products are rapidly emerging. The heating tobacco product heats the tobacco medium at low temperature by a heating appliance, and the tobacco medium is heated and atomized by the appliance to bring the feeling of smoking tobacco to smokers. Compared with the traditional cigarette, the tobacco product which is not combusted by heating has the advantages of low harmful components, mild smoking feeling, low irritation, faint scent when being eaten, and the like. Meanwhile, the electronic cigarette has the characteristics of high electronic cigarette smoke dissipation speed, small side-stream smoke and low harm of second-hand smoke.

In the current tobacco market, the heated cigarettes expand rapidly, and representative foreign products are as follows: iQOS of Felmo International, glo of Enmei tobacco, and Ploom of Nicotiana tabacum. Along with the continuous enhancement of the smoke control supervision, the heated cigarettes are gradually brought into the smoke control supervision, the use places are also limited, the smoke control force is gradually connected with the traditional tobacco, and although the data show that the toxic substances of the heated non-combustible cigarettes are reduced by more than 90 percent compared with the traditional tobacco products, the safety risk also exists in long-term smoking, and the tobacco products with lower harm tend to be generated. The heating temperature of IQOS is about 350 ℃, the heating temperature of Glo is about 250 ℃, and documents report that the release of harmful components in heated cigarettes is reduced along with the reduction of the temperature, and glycerol is mostly adopted as an atomizing agent for heating non-burning cigarettes on the market, the boiling point of the glycerol is 290 ℃, and the heating temperature is more than 200 ℃. In the experimental process, cigarettes on the market which are not burnt during heating are heated at 160 ℃, no smoke exists in the front 5 mouths, water mist can be generated, and only a small amount of nicotine is mixed in water vapor. In order to reduce the heating temperature, a new low-boiling point atomizing agent needs to be researched and developed again, but a cigarette which is not heated and burns and is made of the low-boiling point atomizing agent only has light smoke when being smoked, while a cigarette which is not heated and burns and is made of glycerol and is smoked on the market is thick white smoke, the vision and smoking experience of a smoker are seriously influenced by the fact that the cigarette which is not smoked and the smoke is thin and caused by the low-boiling point atomizing agent, and the psychological satisfaction of the smoker is low.

Therefore, the invention aims to design a smoking material with a moderate smoke amount above, certain physiological satisfaction and obvious tobacco fragrance in a heating temperature range of 120-200 ℃ to meet the demand of people on heating tobacco products with lower harm in the future.

Disclosure of Invention

The invention aims to solve the technical problem of providing a smoke agent aiming at the defects of the prior art, which can ensure that a smoke material meets the requirements of more than medium smoke amount, certain physiological satisfaction and obvious tobacco fragrance in a heating temperature range of 120-200 ℃.

The invention also provides a smoking material prepared by using the smoking agent.

The invention also provides a preparation method of the smoking material.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows:

a smoke agent comprises a fogging solvent with a boiling point of 150-250 ℃, a coordination aid and a solvent, wherein the fogging solvent and the coordination aid are dissolved in the solvent to prepare the smoke agent, and the coordination aid is one or a mixture of more of polyethylene glycol 200-10000.

As is known, polyethylene glycol has a slow-release effect on nicotine. The invention dissolves the fogging solvent with the boiling point of 150-250 ℃ and the polyethylene glycol in the solvent, and the prepared smoke agent can not only adjust the nicotine content, but also increase the smoke amount. The fogging solvent with the boiling point of 150-250 ℃ can also produce thick white fog, thereby improving the vision and the smoking experience of smokers and the psychological satisfaction of smokers.

More preferably, the fogging solvent has a boiling point of 160 to 240 ℃, and even more preferably, the fogging solvent has a boiling point of 180 to 220 ℃.

Preferably, the coordination aid is one or a mixture of 1000-8000 of polyethylene glycol. Further preferably, the coordination aid is one or a mixture of polyethylene glycol 4000-8000.

Preferably, the mass fraction of the fogging solvent is 5% -30%, and the mass fraction of the coordination aid is 1% -10%. Further preferably, the mass fraction of the fogging solvent is 10% -20%, and the mass fraction of the coordination aid is 2% -6%.

Preferably, the fogging solvent is one or a mixture of butanediol, pentanediol, xylitol and propylene glycol. Butanediol, pentanediol, xylitol or propylene glycol can be independently selected, two or three of butanediol, pentanediol, xylitol and propylene glycol can be mixed, and when a mixed fogging solvent is adopted, no special requirement is imposed on the proportion of butanediol, pentanediol, xylitol and propylene glycol.

Preferably, the fogging solvent is 1,3-butanediol, and the safety is high.

1,3-butanediol carries nicotine and other components out of tobacco when forming smoke at 160 ℃, compared with the main atomization agent propylene glycol and glycerol on the market, 1,3-butanediol has higher safety (rat oral acute toxicity: 1,3-butanediol is 29600mg/kg,1,2-propanediol is 20000mg/kg, and glycerol is 26000 mg/kg) and weaker sweet sense (compared with propylene glycol).

Preferably, the smoke agent further comprises a surfactant, and the surfactant is a linear carboxylic acid type surfactant having 11 or more carbon atoms. Specifically, one or more of palmitic acid, stearic acid, oleic acid, linoleic acid and linolenic acid may be used in combination, but not limited to the above examples. Besides the linear carboxylic acid surfactant, tween 80, span 80 and glycerol monolaurate can be selected. When the heating temperature is 120-200 ℃, the surfactant can promote the release of tobacco components under the condition that the smoke amount is not affected.

Further preferably, the surfactant is palmitic acid. Not only can promote the release of tobacco components, but also can not bring other peculiar smell and has harmonious smoke.

Preferably, the mass fraction of the surfactant is 1% to 10%. More preferably, the mass fraction of the surfactant is 1% to 5%. More preferably, the mass fraction of the surfactant is 1% to 3%.

The invention also discloses a smoking material which comprises the smoking agent and a smoking material auxiliary agent, wherein the mass fraction of the smoking agent is 20-40%.

The smoking material can generate moderate or more smoke amount at the heating temperature of 120-200 ℃, has stronger tobacco fragrance and physiological satisfaction, and has the characteristics of lower harm, easy miniaturization of a heating appliance and no need of a cooling means.

Preferably, the mass fraction of the smoke agent is 30-40%.

The invention also discloses a preparation method of the smoking material, which comprises the following steps:

s1, mixing a smoking material auxiliary agent with a smoking agent to prepare a smoking material;

s2, drying the smoking material to obtain the smoking material.

The invention utilizes butanediol, pentanediol or xylitol to form smoke at 120-200 ℃ to carry nicotine and other components out of tobacco. The invention adds the polyethylene glycol into the fogging solvent, solves the problems of small smoke amount and light smoke when smoking the smoking material, and ensures that the fogging solvent with the boiling point of 150-250 ℃ can also produce thick white fog. Meanwhile, the release of free nicotine is excessive, the physiological strength of the free nicotine needs to be reduced, and the polyethylene glycol can inhibit the release of nicotine, but does not influence the release of other components obviously, so that the effects of regulating the nicotine content and increasing the smoke amount are achieved. In order to increase the release of other components in tobacco, surfactants are used as promoters of the release of other components in tobacco.

The smoking material auxiliary agent can adopt the components and the proportion of the existing smoking material auxiliary agent, for example, calcined diatomite, tobacco extract, plant extract, tobacco powder, essence, adhesive and other auxiliary agents can be adopted as the smoking material auxiliary agent. The specific manufacturing method comprises the following steps: adding tobacco extract, plant extract and essence into fuming agent, dissolving, adding diatomite for adsorption, and standing; and mixing the adsorbed diatomite with the tobacco powder, adding an adhesive and other auxiliaries to prepare a smoking material, and drying the smoking material to obtain the tobacco powder.

The invention has the advantages that the smoke generating material generates more than moderate smoke amount, has certain physiological satisfaction and obvious tobacco fragrance in the heating temperature range of 120-200 ℃, and can meet the requirements of people on heating tobacco products with lower harm in the future. The smoking requirement of consumers is met, and at a lower heating temperature, the release of harmful substances in the tobacco is less; the heat insulation requirement of the heating appliance is reduced at lower heating temperature, the appliance is easier to miniaturize, and the portability convenience is enhanced; at a lower heating temperature, the smoke generated by the smoke generating material does not need to be cooled, and the phenomenon of mouth burning during suction is avoided.
