Description
Technical Field
The invention belongs to the technical field of cigarettes, and particularly relates to cigarette paper capable of reducing the ash condensation property of cigarettes and improving the whiteness of ash columns, a preparation method and application thereof.
Background
Twenty years ago, cigarette paper only plays a main role, and cut tobacco is wrapped on a 5000-6000 cigarettes/min cigarette machine, so that the cigarette paper becomes a firm and unbroken cigarette rod. The core indexes of the traditional cigarettes are gram weight and air permeability, but the current cigarette paper must meet various functions, such as meeting the odor absorbing requirement, providing exquisite appearance support for brand images, and even requiring certain fireproof functions in developed countries such as the United states, europe and the like. It can be seen that cigarette paper has not only played the role of wrapping tobacco but also carries more functionalization.
In recent years, as the apparent quality of cigarettes is pursued by consumers, designers fill more elements into cigarette paper, and the ash condensation performance of the cigarettes is one of the elements. The ash condensation refers to the ability of columnar ashes (including external cigarette paper ashes and internal tobacco ashes) present after the combustion of cigarettes to maintain their columnar appearance without fly ash generation. The cigarettes with better ash condensation often bring the quality of consumers to the feeling of riding, and meanwhile, the probability of causing fire because of landing of residual sparks in the cigarette ash can be reduced, so that the cigarettes also become one of the targets of improving cigarette products for various large cigarette enterprises.
At present, the common methods for improving the ash coagulation property of the cigarettes from the viewpoint of cigarette paper mainly comprise the following steps: firstly, increasing the gram weight of the cigarette paper, namely increasing the amount of calcium carbonate serving as a filler, but the change of properties such as air permeability and the like of the cigarette paper is brought, so that various indexes of the cigarette are influenced, the tar release amount of the cigarette is the greatest influence of the indexes, and the tar release amount of the cigarette is increased by increasing the calcium carbonate; in addition, the actual retention of calcium carbonate on cigarette paper is also limited, and excessive use of calcium carbonate may cause problems such as uneven calcium carbonate dispersion. Second, increasing the amount of sodium citrate in the cigarette paper; sodium citrate is used as a common combustion regulator for cigarette paper, and has the main effects of reducing the combustion rate of the cigarette paper, enabling the combustion rate of the cigarette paper to be matched with tobacco shreds, thereby improving the ash wrapping effect, but has the defects of increasing the number of suction ports of the cigarettes and obviously improving the tar content. Thirdly, phosphate is added as a lime setting agent, the effect of the method is most remarkable, but the sensory quality of the cigarette product is greatly affected, and the whiteness of the cigarette ash column is greatly reduced. In addition, the inventors have previously tried to improve the whiteness of the cigarette ash column by adding calcium acetate, see patent CN 2020113549686; however, the method of the patent has no obvious effect on improving the ash coagulation property of the cigarettes, and the production process and equipment are required to be changed, so that the investment cost is high.
The present invention has been made to solve the above problems.
Disclosure of Invention
The soluble calcium salt is added in the cigarette paper manufacturing process, so that the soluble calcium salt reacts with the conventional combustion regulator citrate to a certain extent, the ash condensation property and the ash column whiteness of the cigarettes are improved, and the manufacturing flow is designed to control the reaction degree and prevent the blockage of production equipment.
The ash condensation index in the invention refers to the value obtained by multiplying the ratio of the partial area of ash cracks of the cigarette paper to the whole area by 100. If the ash crack portion area occupies 5.0% of the whole area, the setting index is 5.0. That is, the higher the setting index, the worse the setting property of the cigarette paper.
The technical scheme of the invention is as follows:
in a first aspect, the invention discloses a cigarette paper comprising calcium carbonate, wherein a soluble calcium salt is added simultaneously with a combustion regulator citrate during the manufacture of the cigarette paper; the addition amount of the soluble calcium salt is 0-30% of the total mass of the calcium carbonate and the soluble calcium salt, and is not 0.
Preferably, the soluble calcium salt is one or more of calcium gluconate, calcium lactate and calcium acetate.
Preferably, the soluble calcium salt is added in an amount of 5 to 20% by mass of the total mass of the calcium carbonate and the soluble calcium salt, based on the mass percentage.
Preferably, the citrate is potassium citrate, sodium citrate or a mixture of both salts added in conventional cigarette manufacture.
The second aspect of the invention discloses a method for preparing the cigarette paper, which comprises the following steps in the sizing stage in the cigarette paper preparation process: spraying or dip-coating the combustion regulator citrate according to a conventional flow; the second step is to directly spray the soluble calcium salt directly from another spray head without drying.
The third aspect of the invention discloses application of the cigarette paper to reducing the ash condensation property of cigarettes and improving the whiteness of ash columns, which is characterized in that the cigarette paper can reduce the ash condensation index by 1-3 units and improve the whiteness of the ash columns by 5-20 units.
In the production process of the cigarette paper, citrate and soluble calcium salt are added step by step, and the citrate and the soluble calcium salt react on the surface of the cigarette paper to generate insoluble calcium salt, while potassium and sodium ions in the citrate serving as a combustion regulator are not influenced, so that the combustion characteristic of the cigarette paper is maintained unchanged. Because the amount of insoluble calcium salt generated in the manufacturing process of the cigarette paper can change along with parameters such as temperature, speed, concentration and the like in the manufacturing process, the specific salt solution concentration of the cigarette paper with the same gram weight and air permeability needs to be corrected to a certain extent according to different process parameters, and the relation between the solution concentration and the addition amount needs to be adjusted according to actual conditions.
Because the fiber has better water infiltration effect than the calcium carbonate added in the paper making process, the added citrate and soluble calcium salt are mainly concentrated in the area uncovered by the calcium carbonate, and the subsequent reaction mainly occurs in the area, so that the distribution of the calcium salt on the surface of the paper tends to be even, as shown in figure 2, and the content of calcium element in the paper is increased.
According to the preparation method of the cigarette paper, in the preparation process of the cigarette paper, the sizing stage is divided into two steps, namely, the combustion regulator citrate is sprayed or dip-coated according to the conventional process; then directly spraying soluble calcium salt from another spray head without drying, and then drying to enable citrate and the soluble calcium salt to chemically react on the surface of the cigarette paper to generate part of calcium citrate; meanwhile, potassium and sodium ions serving as combustion regulators are still reserved on the cigarette paper, so that the combustion effect is not affected. Wherein, the addition of the soluble calcium salt is the same as the addition of the citrate, but the addition is needed in two steps. The two-step sizing mode disclosed by the invention is characterized in that a drying link cannot be added between two-step sizing to ensure that the ionic reaction between citrate and soluble calcium salt is smoothly carried out. The reason why the two salts cannot be directly sprayed after being mixed is that the soluble calcium and the citrate can directly generate precipitation in the solution, so that the spray head is blocked, and the production flow cannot be continued. Citrate can be applied by spraying or dipping, while soluble calcium salts are applied by spraying to prevent small amounts of sediment from accumulating in the trough and thus hampering production.
The third aspect of the invention provides an application of the cigarette paper capable of improving whiteness of cigarette ash columns, which can reduce the condensation index by 1-3 units and improve the whiteness of the cigarette ash columns by 5-20 units when used in cigarettes.
Compared with the prior art, the invention has the following beneficial effects:
1. the ash setting index of the cigarette paper is improved: the cigarette manufactured by using the cigarette paper is tested for the setting index according to a standard method, and the setting index is generally reduced by 1-3 units.
2. The whiteness of the cigarette paper roll ash column is obviously improved: the cigarette manufactured by using the cigarette paper is tested for ash column whiteness according to a standard method, and the ash column whiteness can be generally improved by 5-20 units.
3. The physical indexes of the cigarette paper and the cigarette of the invention have no obvious change: because the reaction time is shorter, the production amount of the calcium citrate is not large, and the physical indexes of the cigarette paper and the cigarette are not obviously changed, so that the calcium citrate can be directly replaced in industrial products.
4. The smoke components and sensory quality of the cigarette of the invention have insignificant changes: through standard method detection and sensory evaluation, the cigarette paper replacement product is found to have insignificant changes in smoke components and sensory quality, and the detection data are basically within the allowable error range. The description may directly replace existing cigarette paper without requiring the follow-up of other design parameters.
5. In the specific preparation process of the cigarette paper, the preparation process is adjusted aiming at the addition of the soluble calcium salt, and the preparation process is divided into two steps in the sizing stage, namely, the combustion regulator citrate is sprayed or dip-coated according to the conventional process, then the soluble calcium salt is directly sprayed from another spray head without drying, and then the soluble calcium salt and the citrate are dried, so that the citrate and the soluble calcium salt react chemically on the surface of the cigarette paper to generate part of calcium citrate; meanwhile, potassium and sodium ions serving as combustion regulators are still reserved on the cigarette paper, so that the combustion effect is not affected.

In the cigarette paper manufacturing process shown in figure 1, a mixture of calcium gluconate and calcium acetate is sprayed and added in a sizing stage 2, wherein the mass ratio of the calcium gluconate to the calcium acetate is 2:1, and the adding amount of the mixture of the calcium gluconate and the calcium acetate is controlled to be 15% of the total mass of the calcium carbonate, the calcium gluconate and the calcium acetate; the final cigarette paper produced was 28g/m 2 、70CU。
Replacing conventional 28g/m cigarette paper 2 The 70CU cigarette paper product was made into cigarettes (8 #) and compared to the original cigarettes (7 #) with the following results:
| sample numbering | Lime set index | Whiteness of ash column | Tar release (mg) |
| 7# | 7.2 | 118.1 | 10.0 |
| 8# | 5.2 | 137.6 | 10.0 |
As can be seen from the table, compared with the original cigarette sample, the same standard cigarette paper (gram weight and air permeability) produced by the method has obviously improved ash condensation index and ash column whiteness, and the smoke release amount is basically unchanged. Through sensory evaluation, the smoke sensory quality of the two cigarettes has no obvious difference, and the two cigarettes can be directly replaced.
Example 5
In the cigarette paper manufacturing flow shown in figure 1, a mixture of calcium gluconate and calcium lactate is sprayed and added in a sizing stage 2, wherein the mass ratio of the calcium gluconate to the calcium lactate is 1:1, and the adding amount of the mixture of the calcium gluconate and the calcium lactate is controlled to be 10% of the total mass of the calcium carbonate, the calcium gluconate and the calcium lactate; the final cigarette paper produced was 32g/m 2 、50CU。
Replacing the conventional cigarette paper with the obtained cigarette paper with 32g/m 2 The 50CU cigarette paper product was made into cigarettes (10 #) and compared to the original cigarettes (9 #) with the following results:
| sample numbering | Lime set index | Whiteness of ash column | Tar release (mg) |
| 1# | 6.8 | 126.3 | 11.0 |
| 2# | 5.1 | 142.5 | 11.0 |
As can be seen from the table, compared with the original cigarette sample, the same standard cigarette paper (gram weight and air permeability) produced by the method has obviously improved ash condensation index and ash column whiteness, and the smoke release amount is basically unchanged. Through sensory evaluation, the smoke sensory quality of the two cigarettes has no obvious difference, and the two cigarettes can be directly replaced.
Example 6

Replacing conventional 36g/m cigarette paper 2 The 50CU cigarette paper product was made into cigarettes (12 #) and compared to the original cigarettes (11 #) with the following results:
| sample numbering | Lime set index | Whiteness of ash column | Tar release (mg) |
| 11# | 6.7 | 132.4 | 11.0 |
| 12# | 4.8 | 145.8 | 11.0 |
As can be seen from the table, compared with the original cigarette sample, the same standard cigarette paper (gram weight and air permeability) produced by the method has obviously improved ash condensation index and ash column whiteness, and the smoke release amount is basically unchanged. Through sensory evaluation, the smoke sensory quality of the two cigarettes has no obvious difference, and the two cigarettes can be directly replaced.
