Technical Field

The invention relates to the technical field of cigarettes, in particular to cigarette paper for improving whiteness of cigarette ash columns and a preparation method and application thereof.

Background

Before 20 years, the cigarette paper only plays a main role, and the cut tobacco is wrapped on a 5000-6000/min cigarette making machine, so that the cigarette becomes a firm and intact cigarette strip. The core indexes of the traditional cigarette are gram weight and air permeability, but the cigarette paper must meet various functions at present, for example, exquisite appearance support must be provided for brand images while the requirement of smoking taste is met, and the developed countries such as America, Europe and the like even require that the cigarette paper must have a certain fireproof function. It can be seen that the cigarette paper not only plays the role of wrapping the cut tobacco, but also bears more functional functions.

In recent years, with the pursuit of improvement of apparent quality of cigarettes by consumers, designers also add more elements to cigarette paper, and the whiteness of cigarette ash columns is one of the elements. The cigarette ash column refers to the columnar ash presented after the cigarette is burnt, and the higher the apparent whiteness is, the feeling of full combustion, clean ash content, high quality and the like can be brought to consumers, so the cigarette ash column also becomes one of the targets of improving cigarette products of each large cigarette enterprise.

At present, the common methods for improving the whiteness of cigarette ash columns from the perspective of cigarette paper mainly comprise: firstly, the gram weight of the cigarette paper is increased, namely the amount of calcium carbonate serving as a filler is increased, but the change of properties such as air permeability and the like of the cigarette paper can be brought about, and finally, various indexes of the cigarette are influenced, the maximum influence is the tar release amount of the cigarette, and the increase of the calcium carbonate can also increase the tar release amount of the cigarette. Secondly, increasing the amount of potassium citrate in the cigarette paper; the potassium citrate is used as a common combustion improver for the cigarette paper, and can improve the whiteness of cigarette ash columns to a certain extent after being added, but the defects that the higher the content of the citrate combustion improver in the cigarette paper is, the higher the smoldering rate of the cigarette paper is, the faster the burning speed of the cigarette is, the less the number of suction openings is, the longer the cigarette cone of the cigarette is under the same burning time, the higher the possibility of the cigarette paper turning outwards is, and the ash performance of the cigarette is poor.

The present invention has been made to solve the above problems.

Disclosure of Invention

The invention improves the whiteness of cigarette ash column and the ash wrapping property of cigarette paper by adding calcium acetate in the cigarette paper manufacturing process, and designs the manufacturing flow, so that potassium citrate/sodium citrate can be normally added as a combustion improver, and the cigarette paper can meet the smoldering state standard.

The ash retention index in the present invention is a value obtained by multiplying the ratio of the area of the cracked portion of ash to the entire area of ash in the wrapper by 100. If the ash crack area is 5.0% of the entire area, the ash index is 5.0. that is, the higher the ash index, the worse the ash wrapping performance of the wrapper.

The invention provides cigarette paper capable of improving whiteness of cigarette ash columns, wherein filler of the cigarette paper comprises calcium acetate and calcium carbonate, and on the basis of mass percentage, the amount of the calcium acetate is 0-30% and is not 0 of the total mass of the calcium carbonate and the calcium acetate.

Preferably, the amount of the calcium acetate is 5-20% of the total mass of the calcium carbonate and the calcium acetate on a mass percentage basis.

In the invention, calcium acetate is added in the cigarette paper manufacturing process to replace part of calcium carbonate as a filler, so that the total mass of the calcium acetate and the calcium carbonate is ensured to be unchanged, parameters such as gram weight, air permeability and the like of the cigarette paper are controlled to be unchanged, and the calcium acetate replacement amount is within 30 percent of the total mass of the calcium carbonate and the calcium acetate. Preferably, the substitution amount of the calcium acetate is 5-20% of the total mass of the calcium carbonate and the calcium acetate, so that the physical indexes and smoke components of the cigarette using the cigarette paper are not obviously deviated. The specific substitution amount can be adjusted according to the actual design requirement of the cigarette.

The second aspect of the invention provides a preparation method of cigarette paper capable of improving the whiteness of cigarette ash columns, wherein in the preparation process of the cigarette paper, after the paper making process, the first drying is carried out, and then calcium acetate is dip-coated; and (3) after finishing dip-coating calcium acetate, carrying out secondary drying, and then carrying out a sizing process, wherein a combustion improver is sprayed in the sizing process.

Wherein, according to the conventional process, calcium carbonate is added in the papermaking process.

The drying process is carried out before and after the calcium acetate is dipped, and the key is that the secondary drying is carried out before the sizing process is carried out after the calcium acetate is dipped, because: and combustion improvers such as citrate can be sprayed in the sizing process, and if the cigarette paper is not dried after being dipped in calcium acetate, the cigarette paper is directly sized, so that the risk of hydrolysis and precipitation of the combustion improvers such as calcium acetate and citrate sprayed in the sizing process can be caused, and the combustion improvers such as citrate are necessary in the cigarette paper and are also necessary conditions for the cigarette using the cigarette paper to meet the smoldering condition standard. Therefore, in order to prevent the risk of hydrolysis and precipitation when the calcium acetate and the citrate or other common combustion improvers are directly mixed, the invention carries out secondary drying after the completion of the calcium acetate dip-coating and before the sizing process.

Preferably, the method for dip-coating calcium acetate is that calcium acetate is dissolved into a certain amount of water according to the required amount and is filled into a material tank; in production, the paper strip conveyed by the roller passes through the solution in the trough, and the calcium acetate is dipped and coated on the paper strip. The concentration of the calcium acetate solution is determined according to the actual required feeding amount and is related to the conveying speed of the paper tape.

In the first drying process and the second drying process, the drying temperature and the drying time are the drying conditions commonly used in the preparation process of the cigarette paper in the prior art, the drying temperature is usually 100-120 ℃, and the drying time is controlled in the way that the time for the paper tape with the length of 1 meter to pass through the drying area is not more than about 1 s.

The third aspect of the invention provides the application of the cigarette paper capable of improving the whiteness of the cigarette ash column, and the cigarette paper can be used in cigarettes to improve the whiteness of the cigarette ash column by 5-20 units and reduce the ash condensation index by 1-3 units.

Compared with the prior art, the invention has the following beneficial effects:

1. the whiteness of the cigarette ash column is obviously improved: the whiteness of ash columns of cigarettes manufactured by using the cigarette paper is detected according to a standard method, and the whiteness of the ash columns can be generally improved by 5-20 units.

2. Improvement of the ash coagulation index: the ash coagulation index of the cigarette manufactured by using the cigarette paper is detected according to a standard method, and the ash coagulation index of the cigarette can be generally reduced by 1-3 units.

3. The physical indexes of the cigarette paper and the cigarettes are not obviously changed: because the substitution amount of calcium acetate is small and the molecular weight of calcium acetate is close to that of calcium carbonate, the physical indexes of the cigarette paper and the cigarette are not obviously changed, and the calcium acetate can be directly replaced and used in industrial products.

4. Cigarette smoke components and sensory quality change are not obvious: 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 instructions may directly replace the existing cigarette paper without any adjustment of other design parameters.

5. In the specific cigarette paper preparation process, the preparation process is adjusted according to the addition of calcium acetate, and after the paper making process flow, the first drying is carried out, and then the calcium acetate is dip-coated; and (3) after finishing dip-coating calcium acetate, carrying out secondary drying, and then carrying out a sizing process, wherein a combustion improver is sprayed in the sizing process. That is to say, all carry out drying process around the dip-coating calcium acetate, the key is, after accomplishing the dip-coating calcium acetate, before carrying out the glueing technology again, carry out the drying for the second time earlier, the reason lies in: and combustion improvers such as citrate can be sprayed in the sizing process, and if the cigarette paper is not dried after being dipped in calcium acetate, the cigarette paper is directly sized, so that the risk of hydrolysis and precipitation of the combustion improvers such as calcium acetate and citrate sprayed in the sizing process can be caused, and the combustion improvers such as citrate are necessary in the cigarette paper and are also necessary conditions for the cigarette using the cigarette paper to meet the smoldering condition standard. Therefore, in order to prevent the risk of hydrolysis and precipitation when the calcium acetate and the citrate or other common combustion improvers are directly mixed, the invention carries out secondary drying after the completion of the calcium acetate dip-coating and before the sizing process.
